Inventors: H W Hirschy and C H Rowe Priority begtird / am. September 30, 1954 (USA) The present invention relates to cellulosic products, and more particularly to laminated sheet materials in the nature of drying materials, appearing primarily but not exclusively of absorbent materials, e.g. cellulose wadding, tissue paper and fiber wadding. The sheet material according to the invention may contain layers of paper fiber radar and adhesive binders in various devices or combinations, which do not necessarily contain all said elements and possibly in some modifications contain one or more other elements.

Foreliggande uppfinning hanfor sig till ett arkmaterial som bestar av ett huvudskikt av absorberande material, vilket bar benagenhet att sonderdelas vid gnidning eller torkning, och ett skyddsnat pa ytan av sagda skikt, vilket nat bestir av starkt material, som mot-star brott till foljd av sadan gnidning eller torkning, 'och är av oppen struktur, som till-later endast 'begransad, direkt beroring rnellan sagda materialskikt och en yta, som gnides eller torkas. The present invention relates to a sheet material consisting of a main layer of absorbent material, which had the tendency to be separated during rubbing or drying, and a protective seam on the surface of said layer, which is composed of strong material which resists breakage due to such rubbing or drying, and is of open structure, which allows only limited, direct contact with the said material layer and a surface which is rubbed or dried.

Figs. 8, 9 and schematically show different experimental steps in the manufacture of products or product elements according to the invention.

Det i fig. 1 visade tyget Or en komponent av manga produkter enligt uppfinningen. Det dr ett icke vavt tyg, som bestar av en sats tradar 1, vilka stracka sig i tygets langdriktning, och en andra sats tradar 2, som stracka sig tvars mot tygets langdriktning. Tradarna i vardera satsen Oro lampligen men icke nodvandigtvis parallella med varandra och belagna pa avsevart avstand fran varandra, varyid satsen av tradar 2 ar belagen helt pa den ena sidan am den andra satsen tra.dar 1, varprate tradsatserna aro anordnade sida mot sida och lampligen hopklistrade, dar tradarna i den en.a satsen korsa tradarna i den andra satsen. The fabric Or shown in Fig. 1 is a component of many products according to the invention. There is a non-woven fabric, which consists of a set of threads 1, which extend in the longitudinal direction of the fabric, and a second set of threads 2, which extend transversely to the longitudinal direction of the fabric. The lines in each set are suitably but not necessarily parallel to each other and are spaced at a considerable distance from each other, the set of lines 2 being coated completely on one side of the other set of lines 1, where the line sets are arranged side by side and suitably glued together, where the trades in one batch cross the trades in the other batch.

Olika typer av apparater 'aro kanda for framstallning av tyg av denna icke vavda, korslagda tradkonstruktion. En sadan apparat visas schematiskt i fig. 8, dar en seria parallella tradar 1 ledas tvars Over en klister- 2— — pafOrincrt'svals 3, som roterar i ett klistertrag 4 och fran vilken tradarna ledas till med mellanrum i omkretsled belagna stallen pa. en. langstrackt, cylindrisk dorn 5. Ett styrorgan 6 tjanar delvis till att leda tradarna till dessa i omkretsled med mellanrum belagna stallen pa dornen. Alltefter den anvanda klistertypen kunna atgarder vara vidtagna for att torka eller delvis torka klistret pa tradarna fOr att hindra vatt klister fran att samla sig pa styrningen 6 och dornen 5, .och lampliga anordningar, t. ex. upphettnings- eller fuktningsorgan kunna Tara anordnade for att anyo aktivera klistret vid erforderlig tidpunkt for att Ora klistret anvandbart for sammanbindning av tradarna eller fastande av andra komponenter vid tradarna 1. Tradarna framniatas i sin langdriktning och en roterande ring 7, som uppbar en eller flera tradspolar 8, sveper tradar runt dornen 5 och de darpa befintliga tradarna 1 for att bilda ett ror 9 av tyg, som bestar av en sats langsgaende tradar och en sats tvargaende tradar, som stracka sig runt tradarna 1. lloret uppskares i lfingdriktningen medelst ett lampligt uppskarinngsorgan 10, och tygroret oppnas darpa till en flat, enkelskiktig tygbana 11. Den Iran spolen 8 pftforda traden bildar salunda tvfirtra.darna 2 av tyget i fig. 1, och dessa tvartradar aro fasta yid tradarna 1 medelst det klister, som pafordes medelst valsen. 3. Ett icke visat, lampligt organ, t. ex. en avskrapningskniv, kan vara anordnat i samband med valsen 3 for att reglera tjockleken ay del pa trAdarna av valsen paf5rda klisterskiktet. Various types of apparatus are known for making fabric from this non-woven, crimped wire construction. Such an apparatus is shown schematically in Fig. 8, where a series of parallel wires 1 are guided transversely across an adhesive roller roll 3, which rotates in an adhesive joint 4 and from which the wires are led to circumferentially spaced stalls pa. one. elongate, cylindrical mandrel 5. A guide means 6 serves in part to guide the wires to these circumferentially spaced stalls on the mandrel. Depending on the type of adhesive used, steps may be taken to dry or partially dry the adhesive on the wires to prevent water adhesive from accumulating on the guide 6 and the mandrel 5, and suitable devices, e.g. heating or humidifying means may be provided to activate the adhesive at the required time to make the adhesive usable for bonding the wires or attaching other components to the wires 1. The wires are provided in their longitudinal direction and a rotating ring 7, which carried one or more wire spools 8, wraps threads around the mandrel 5 and the darpa existing threads 1 to form a tube 9 of fabric, which consists of a set of longitudinal threads and a set of transverse threads, which extend around the threads 1. The yarn is cut in the direction of the finger by means of a suitable cutting means. 10, and the fabric tube is opened darpa to a flat, single-layer fabric web 11. The Iran spool 8 pftforda thread thus forms the two-quarter threads 2 of the fabric in Fig. 1, and these cross-threads are fixed to the threads 1 by means of the adhesive applied by the roller. 3. A lamp (not shown), e.g. a scraping knife, may be provided in connection with the roller 3 to adjust the thickness ay part of the threads of the roller applied to the adhesive layer.

Tvartradarna 2 aro effektivt fasta vid de langsgaende tradarna 1, men klisterforstyvning ay det av korslagda tradar besthende tyget undvikes Lida i avsevard grad. Klisterforstyvning ay tyget undvikes fOr det forsta genom att konstruera tyget Tried en sats tradar, tvartrhdarna 2 i detta fall, fria fran klister mellan tradkorsningsstallena, sâ att tvartradarna mycket nara bibehalla hela sin normala biljlighet och mjukhet. Klisterforstyvfling ay tyget undvikes fiven i viss man, &A, sasom i foreliggande fall, de fran klister fria tradarna aro i stand att absorber. och Amen absorbera klister fran de klisteroverdragna tradarna pa korsningsstallena, sa att det pa varje korsningsstalle i sjalva verket finnes en. minskad mangd klister i eller pa de klisteroverdragna tradarna. Detta medfOr, att traden mom ett kort parti vid korsningsstallet fir nagot mera Wig an mom de partier ay traden, som uppbara full mangd klister. Det ma papekas, alt absorptionen ay klister pa detta salt vid tra.dkorsningsstallena icke namnvart paverkar bojligheten ay tvartradarna, som med undantag fOr sadant absorberat klister aro fria Iran klister. The cross threads 2 are effectively attached to the longitudinal threads 1, but adhesive stiffening of the fabric consisting of crossed threads avoids Lida to a considerable extent. Adhesive stiffening of the fabric is avoided in the first place by designing the Tried fabric a set of threads, the crossbars 2 in this case, free of glue between the thread crossing stalls, so that the crossbars very closely maintain all their normal cheapness and softness. Adhesive stiffening of the fabric is avoided in some cases, & A, as in the present case, the non-adhesive threads are able to absorb. and Amen absorb glue from the adhesive coated wires at the crossing stalls, so that at each crossing stall there is in fact one. reduced amount of adhesive in or on the adhesive coated wires. This means that the trades mom a short lot at the crossing stall fir slightly more Wig an mom de parties ay traden, which collect full amount of glue. It must be noted that the fact that the absorption of glue on this salt at the tradsorsingsstallene does not significantly affect the flatness of the transverse wires, which, with the exception of such absorbed glue, are free Iran glue.

Klisterf5rstyvning ay tyget kan ytterligare undvikas genom att astadkomma bildande av klistermistor eller klisterfria tra'dpartier 13 mer eller mindre i enlighet med det amerikanska patentet 2 564 689. Detta kan ske genom att sa utforma eller driva klisterpaforingsvalsen 3, att klistret kommer att phfOras de langsgaende tradarna 1 diskontinuerligt. Exempelvis kan valsen 3 vara forsedd med en eller flera urtagningar, som icke komma att fora klister till tradarna, eller ocksà kan valsen hava slat yta och arbeta med en ythastighet, som fir nagot mindre an re,- relsehastigheten ay tradarna 1, sd att klistret far benagenhet att utstrykas langs tradarna 1, da de lamna valsen 3. Detta forhallande kan vara sadant, att klisteroverdragen i sjalva verket komma att gâ sOnder pa olika stallen, varigenom erhallas htminstone korta, klisterfria stycken fangs de langsgaende tradarna 1, sasom antydes yid 13 i fig. 1. Adhesive stiffening of the fabric can be further avoided by providing the formation of adhesive mists or adhesive-free wire portions 13 more or less in accordance with U.S. Patent 2,564,689. This can be done by designing or operating the adhesive pore roller 3 so that the adhesive will fit the longitudinal traders 1 discontinuously. For example, the roller 3 may be provided with one or more recesses which will not lead glue to the threads, or the roller may also have a smooth surface and work at a surface speed which is somewhat less than the speed of the threads 1, so that the adhesive may tend to be spread along the threads 1, as they leave the roller 3. This condition may be such that the adhesive coatings will in fact break apart in different places, whereby at least short, adhesive-free pieces are obtained in the longitudinal threads 1, as indicated by 13 in Fig. 1.

Om sa foredrages,kan klisterphforingsvalsen 3 vara forsedd med ett skruvlinjeformigt eller annorlunda beskaffat spar 3a, som avbryter klisterpafOringen pa sa. salt, att klistermistorna 13 ph varje trad komma att vara forskjutna i fOrhallande till klistermistorna pa intilliggande tradar, sasom antydes i fig. 1. Vid donna anordning är det tamligen sakert, att inga tvartradar 2 komma att ber5ra klistermister pO. intilliggande, klisterforsedda tradar 1, varigenom tillfredsstallande bindning ay tvartradarna 2 vid langstradarna 1 sakerstalles. If so, the adhesive liner roller 3 may be provided with a helical or differently shaped groove 3a, which interrupts the adhesive lining thereon. salt, that the stickers 13 ph each thread will be offset in relation to the stickers on adjacent threads, as indicated in Fig. 1. With this device, it is quite certain that no crosswires 2 will touch the stickers on. adjacent, glued threads 1, whereby satisfactory bonding of the transverse threads 2 to the longitudinal threads 1 is secured.

Vid vissa utforingsformer av apparaten for framstallning av tyg ay korslagda tradar aro de i f5rhallande till varandra korslagda tradarna riktade diagonalt i stallet fOr i langdled och tvarled i forhallande till langden av det framstallda tyget, varvid den erhallna banan da. allmant kan karakteriseras sasom en diagonalrutnatbana. Sadana banor kunna i vissa produkter anvandas i stallet fOr en bana med i langdriktningen och tvarriktningen sig strackande tradar, sasom visas i fig. 1. In certain embodiments of the apparatus for making fabric of crossed threads, the threads crossed in relation to each other are directed diagonally in the stall for longitudinal and transverse in relation to the length of the fabric produced, the resulting web then. can generally be characterized as a diagonal grid path. Such webs can in some products be used in the stable for a web with trades extending in the longitudinal and transverse directions, as shown in Fig. 1.

Tyg med korsvis anordnade tradar hava hittills framstallts av forhallandevis styva, tunga fibrer, sasom glas, hampa osv., fOr att bilda fOrstarkningsbanor, sarskilt vid vissa slags byggnadspapper och tjockt omslagspapper. De salunda formade, harda och styva naten aro icke lampade fOr de hr avsedda produkterna, som i allmanhet skola vara mjuka och bojliga och i stand att bliva vikta och hopkramade liksom mjukt textilmaterial. Fabrics with cross-arranged threads have hitherto been made of relatively stiff, heavy fibers, such as glass, hemp, etc., to form reinforcing webs, especially with certain kinds of building paper and thick wrapping paper. The well-shaped, hard and rigid seams are not suitable for the products intended here, which in general should be soft and flexible and able to be folded and hugged as well as soft textile material.

For aft uppna mjukheten och vissa andra egenskaper hos det av korslagda tradar bestaende tyget ar det lampligt, att tradarna 1 och 2 hava formen ay liten snodd uppvisande, flerfibriga trhdar till skillnad fran vanliga tradar ay spunna fibrer. Dessa flerfibriga tradar kunna vara utforda am rayonsilke, nylonsilke och kontinuerliga fibrer ay andra material, som kunna formas till de 5nskade, mycket bOjliga fibrerna med liten tjocklek. Vid ett utforingsexempel framstalldes de — —3 langsgaende tradarna 1 .av trettio rayonsilkefibrer, som hopfarts till tradar med en tjocklek av 75 den., medan tvartradarna 2 voro framstallda av fyrtio sadana fibrer, som sammanforts till tradar med en tjocklek av 100 den. Alla tradarna hade liten snodd, i det att de langsgaende tradarna hade ungefar 2 1/2 snoddvary per 25 mm och de tvargaende tradarna omkring 4 snoddvarv per 25 mm. I allmanhet bora de flerfibriga tra'darna hava en tjocklek mom omrd.det omkring 30150 den, och bora innehalla 2-150 enskilda silkefibrer med en tjocklek mom omrd.det omkring 1-15 den., varjamte tradarna b5ra hava en mindre snodd an 6 vary per 25 mm. In order to achieve the softness and certain other properties of the fabric consisting of crossed threads, it is appropriate that threads 1 and 2 have the shape of a small twine having, multi-fiber threads unlike ordinary threads of spun fibers. These multi-fiber threads can be challenged with rayon silk, nylon silk and continuous fibers and other materials, which can be formed into the desired, very flexible fibers of small thickness. In one embodiment, the longitudinal threads 1 were made of thirty rayon silk fibers, which were assembled into threads with a thickness of 75 den, while the transverse threads 2 were made of forty such fibers, which were assembled into threads with a thickness of 100 den. All the trades had a small twist, in that the longitudinal trades had about 2 1/2 twist turns per 25 mm and the transverse threads about 4 twist turns per 25 mm. In general, the multi-fiber threads should have a thickness in the range of about 30,150 den, and should contain 2-150 individual silk fibers with a thickness in the range of about 1-15 den., And the threads should have a smaller twist of 6 vary per 25 mm.

Tra.dar av den antydda konstruktionen med flera fibrer och lag snodd aro mycket bajliga och .mjuka, och till faljd av spolning och annan hantering hava sadana tradar benagenhet att 'antaga en nagot avplattad eller oval form, sasom antydes vid 14 i fig. 2. Da tra.- dar av denna karaktar laggas i kors for att bilda tyget enligt fig. 1, hava fibrerna benagenhet sprida sig vid tradarnas korsningsstallen. sit att det bildas avplattade, okad bredd uppvisande korsningsstallen, sasom framgar av fig. 1. Denna avplattningseffekt itr mycket anskvard och kan akas genom att utava svagt tryck far att pressa tvartradarna 2 till intim beroring med langstradarna 1. Denna airplattningseffekt kan aven okas genom gnidfling, borstning eller annan bearbetning av tradarna antingen mom de lokala tradkorsningsstallena eller hangs tradarnas hela langd for ,att avplatta tradarna utover hela deras langd. Sadan avplattning utover hela langden Sr i allmanhet mycket onskvard, eftersom den minskar tjockleken av den av varandra korsande tradar bestaende banan, set an denna bana kan lattare infarlivas med ett laminerat ark med ett minimum av synliga tee-ken pa narvaron av det av varandra korsande tradar bestagnde tyget i arket. Trades of the indicated construction with several fibers and layers twisted are very flexible and soft, and due to flushing and other handling, such trades have a tendency to assume a somewhat flattened or oval shape, as indicated at 14 in Fig. 2. When threads of this character are laid crosswise to form the fabric of Fig. 1, the fibers tend to spread at the crossing stalls of the threads. As shown in Fig. 1. This flattening effect is very difficult and can be agitated by applying weak pressure to press the transverse wires 2 into intimate contact with the longitudinal wires 1. This air flattening effect can also be increased by rubbing , brushing or other processing of the trades either in the local trade crossing stalls or hanging the entire length of the trades to flatten the trades beyond their entire length. Such flattening over the entire length is generally very inconvenient, as it reduces the thickness of the intersecting threaded web, since this web can be more easily incorporated with a laminated sheet with a minimum of visible signs of the presence of the intersecting web. tradar held the fabric in the sheet.

Ett av tradkorsningsstallena efter utavande ,av latt tryck visas i starre skala i fig. 4, dar langstraden 1 visas avplattad till endast obetydligt ,mera an halften air trd.dens normala tjocklek, medan tvartra.den 2 Sr ,avplattad pa liknande sift •och i sjalva verket Sr forsedd med en fOrdjupning for upptagning av den avplattade langstraden 1. Dada tradarna aro givetvis pressade in i varandra, sit att langstraden 1 i sidoprojektion skulle se ut i huvudsak pa samma salt som tvartraden 2 I fig. 4. Denna avplattning av de korslagda tradarna pa korsningsstillena medf Sr i hog grad undvikande air sadan alltf8r stor tjocklek air 'tyget som vanligen forefinnes i vavda tyger pa tradkorsningsstallena, och den tjanar i viss man till att Oka ingreppsytorna pa de varandra korsande tradpartierna, sit att klisterforbandet mellan sadana partier forloattras och starkes avsevart. Det ,ar .oeksa tydligt, att minskningen av tradarnas tjock- lek pa korsningsstallena medlar 8kad Mpg-het av tradarna mom dessa omraden med minskad tjocklek. One of the wire crossing stalls after exhalation, of light pressure is shown on a larger scale in Fig. 4, where the longitudinal wire 1 is shown flattened to only insignificant, more than half the normal thickness of the wire wire, while the transverse wire is flattened on a similar sieve. in fact Sr is provided with a recess for receiving the flattened longitudinal line 1. These threads are of course pressed into each other, since the longitudinal line 1 in side projection would look essentially on the same salt as the transverse line 2 In Fig. 4. This flattening of the crossed threads on the crossing stilts entail highly avoiding air such as the excessive thickness of the air fabric which is usually found in woven fabrics on the crossing stilts, and it serves in a certain way to increase the engagement surfaces on the intersecting threaded sections, so that the adhesive bond between such abandoned and strong enough. It is also clear that the reduction in the thickness of the trades at the crossing stables means an increased Mpg content of the trades in these areas with a reduced thickness.

Den vid framstallning av tyget enligt fig. 1 begagnade konstruktionen ay vid varandra fastklistrade, lag snoddgrad uppvisande tra- dar medfor ett mycket mjukt men dimensionsstabilt tyg. Emellertid kunna vanliga, spunna trddar anvandas, men de aro forhallandevis harda. Om spunna tradar med liten snoddgrad anvandas for aft uppna mjukhet, bliva tradarna svaga, om de icke utforas med stor diameter. The construction used in the production of the fabric according to Fig. 1 ay glued to each other, having a low degree of twist, results in a very soft but dimensionally stable fabric. However, ordinary, spun threads can be used, but they are relatively hard. If spun threads with a small degree of twist are used to achieve softness, the threads become weak if they are not made with a large diameter.

Det anvanda klistret kan vara av vilken som heist typ, som Sr lampad for det andamal, for vilket tyget Sr framstallt. En klistertyp, som Sr allmant anvandbar fOr framstallning av tyg enligt fig 1 och som Sr sarskilt lamp- lig far paforing mcdelst en paforingsvals, Sr en polyvinylacetatlasning, som innehaller ett mjukningsmedel. Ett exempel pa ett sadant klister kan innehalla 30 % polyvinylacetat, 67 % losningsmedel (kommersiell »Solox», ett preparat med alkoltolhuvudbestandsdel) och 3 % dibutylftalatmjukningsmedel. The adhesive used may be of any type, as Sr lamped for the purpose for which the fabric Sr is made. A type of adhesive which is generally usable for the production of fabric according to Fig. 1 and which is particularly suitable for lining by means of a lining roll, is a polyvinyl acetate seal containing a plasticizer. An example of such an adhesive may contain 30% polyvinyl acetate, 67% solvent (commercial "Solox", a preparation with an alcohol toluene main ingredient) and 3% dibutyl phthalate plasticizer.

For ma'nga andamal bar lampligen klistret vara sadant, att det forblir bojligt och icke intranger djupt i tradarna utan snarare liar benagenhet att forbliva pa tradarnas yta. Klister air emulsionstyp, plastisoltyp eller or- ganisoltyp kunna begagnas liksom varm- smaltningsklister, t. ex. polyeten. Klister, som aro termoplastiska till sin natur, are vanli- gen att foredraga och kunna verksamgoras eller mjukas ph. nytt genom uppvarmning eller genom anvandning av lampliga losnings- model f Sr att tillata tryckinbaddning av den ena satsen tradar i det klister, som uppbares av den andra tradsatsen, och for att under- latta laminering av ,andra material pa den av varandra korsande tradar bestaende banan med tillhjalp air det klister, som uppba.- res air banan. Det .anvanda klistret bar givet- vis valjas med hansyn till den anvandning, som tyget skall hava. I vissa fall bora vatten- fasta klister begagnas, och i andra fall kunna oljefasta klister erfordras. I andra fall kunna vattenfasthet •och oljefasthet vara utan betydelse, medan daremot bOjlighet och styrka air forbandet aro air primart intresse. For many occasions, the adhesive should have been such that it remains flexible and does not penetrate deep into the threads, but rather has a tendency to remain on the surface of the threads. Adhesives air emulsion type, plastisol type or organisol type can be used as well as hot melt adhesives, e.g. polyethylene. Adhesives, which are thermoplastic in nature, are usually preferred and can be applied or softened ph. new by heating or by using suitable unloading models to allow pressure embedding of one batch of wire into the adhesive carried by the other batch, and to facilitate lamination of other materials on the intersecting wire. the web with the aid of air the adhesive, which is collected.- res air the web. The used adhesive should, of course, be chosen with a view to the use which the fabric is to have. In some cases, water-resistant adhesives are used, and in other cases oil-resistant adhesives may be required. In other cases, water resistance and oil resistance may be insignificant, while flexibility and strength of the air connection are of primary interest.

For manga andamal kan pa en av korslagda tradar be,sta.ende tygbana, sasom visas i fig. 1, vara anbragt ett paldgg 15 av fibrer, t. ex. bomull eller konstfibrer. Detta palagg kan hava formen air en kardad eller pa an- nat salt forenhetligad bana, men far manga andamal kan detta palagg besta av ett mycket tunt, latt och ytterst lattgenomtrangligt skikt av fibrer. For vissa andamal Sr det onskvart med ett fiberskikt eller palagg med en vikt av omkring 1,8 g/m2 av tyget. Ett latt palagg av fibrer av denna karaktar Sr mycket genomtrangligt far vatska och minskar icke .namnvart genomtrangligheten ay — — tradtyget. Trots detta bildar palagget ett halje eller en skarm, som giver tradbanan ett slatt och mjukt grepp. Ett sadant fiberpalagg kan anbringas pa hada sidorna av tradbanan, men det Sr vanligen icke nodvandigt, sarskilt (la banan är av appen natkonstruktion, t. ex. med en maskstorlek av 5 X 5 mm eller t. o. m. 1,4 X 1,8 mm, eftersam nagra av de ph den ena sidan paforda fibrerna vanligen komma att skjuta genom banan i sadan grad, att en slatgaringseffekt är latt iakttaghar pa. bada sidorna av banan. For many purposes, a pile of fibers 15, for example, can be placed on a fabric web standing on one of the crossed threads, as shown in Fig. 1. cotton or man-made fibers. This garment can have the shape of a carded or otherwise salt-unified web, but for many purposes this garment may consist of a very thin, light and extremely easily permeable layer of fibers. For some purposes it is desirable to have a fibrous layer or garment weighing about 1.8 g / m2 of the fabric. A light pallet of fibers of this character is very permeable and does not reduce the permeability of the yarn fabric. Despite this, the pallet forms a veil or a screen, which gives the treadmill a smooth and soft grip. Such a fiber garment can be applied to both sides of the wire web, but it is usually not necessary, especially (the web is of the app night construction, for example with a mesh size of 5 X 5 mm or even 1.4 X 1.8 mm, After some of the fibers on one side of the fibers usually come to slide through the web to such an extent that a slatting effect is easily observed on both sides of the web.

Fibrerna i det icke vavda palagget 15 kun- nafastklistrade md tradbanan, sasom forklaras i det foljande och dessa fibrer hava lampligen sadan langd, att tamp av fibrerna komma att overbrygga intill varandra liggande tradar och stracka sig tvars over de av de varandra korsande tradarna bildade vinklarna for att darigenom fasthalla oeh staga tradarna i deras onskade hopmonteringsforhallande. Denna fiberforbindning av bade parallella och korsande tradar kan upptrada Siren i franvaro ay klisterforbindning mellan fibrerna och tradama, eftersom fibrerna hava en inneboende benagenhet 'att haka fast yid tradarna, men sagda stabiliseringseffekt uppnas formodligen bast, da fibrerna aro fastklistrade vid tradama. The fibers in the non-woven pallet 15 can be glued to the wire web, as explained below, and these fibers are suitably so long that tampons of the fibers come to bridge adjacent wires and extend across the angles formed by the intersecting wires. in order to thereby hold on and stay the traders in their desired assembly relationship. This fiber connection of both parallel and intersecting threads can occur in the absence of an adhesive connection between the fibers and the threads, since the fibers have an inherent tendency to get caught in the threads, but said stabilizing effect is probably best achieved when the fibers are glued to the threads.

Fiberphlagget 15 kan pafaras medelst olika typer av mekanismer, av vilka en visas sasom exempel i fig. 9, dar en vadd 16 av det utvalda fibermaterialet matas i andled mot en rivvals eller ett liknande uppluckringshjul 17, som river sande' madden 16 och ay-giver en strain 18 av fibrer mot en tygbana 19 ay korslagda tradar for att darigenom bilda palagget 15 pa den ,ena sidan av tyget, som Sr bildat ay tvartradarna 2.

The fiber flag 15 can be padded by various types of mechanisms, one of which is shown as an example in Fig. 9, where a batt 16 of the selected fibrous material is fed inwardly against a tear roller or a similar pick-up wheel 17, which tears the sand 16 and ay. provides a strain 18 of fibers against a fabric web 19 in crossed threads to thereby form the pallet 15 on the one side of the fabric formed by the transverse threads 2. The fabric in the crossed threads 19 can be guided to the working zone of the grating wheel 17 directly from the apparatus by means of which the fabric is made so that the adhesive on. the longitudinal trades 1 remain at least somewhat active on. its surface mom the zone where fibers are deposited on the fabric.

Klisterferbandet mellan fibrerna och tradarna och mellan tradarna inbordes kan for-Ultras avsevart genom att leda den med fibrer pa. ytan forsedda, av korslagda trader besta.ende tygbanan genom en kalandervalsanordning 20. Tvartthdarna 2 pressas darigenom in i det av de langsgaende tradama 1 uppburna klistret, °eh tradarna pressas in i varandra for att uppna den tradplattningseffekt, som visas i fig. 4 och. medlar Rad area ay klisterforbandet Indian tradarna. Fiberpalagget pressas aven in i tradtyget, och nagra av fibrerna bringas att mera fullstandigt bliva inbaddade i det am tradarna 1 uppburna klistret far att sakrare fasta fiberpalagget pa den av korslagda trader bestaende banan. Sasom visas i fig. 3, synes fiberpalagget 15 efter att hava blivit pressat mot banan ay korslagda tradar att vara mer eller mindre sammanpressat inom omradena for tradarna, sasom visas mid 21, medan fiberpalagget bibehaller ett fOrhallandevis last tillstand inom omradena for mellanrummen mellan trhdarna i tyget, sasom visas mid 22, dar nagra av fibrerna amen Oro bragta att tranga genom tyget till den sida ay delta, som är motsatt den sida, pa. vilken fibrerna fran borjan anbragts. Omradena for mellanrummen tradarna bilda den overvagande delen ay tygets area, sa att det losa tillsta.ndet am fiberpalagget mom dessa omraden giver en totaleffekt ay luddighet och mjukhet. The adhesive bond between the fibers and the threads and between the threads is embedded can be pre-Ultrated considerably by conducting it with fibers on. surface provided with crisscrossed yarns through a calender rolling device 20. The quadrants 2 are thereby pressed into the adhesive supported by the longitudinal yarns 1, and the yarns are pressed into each other to achieve the yarn plating effect shown in Fig. 4 and . med area Med ay klisterforbandet Indian tradarna. The fibrous garment is also pressed into the yarn fabric, and some of the fibers are caused to become more completely embedded in the adhesive carried in the yarns 1 so that the fibrous garment is more securely fastened to the web consisting of crossed yarns. As shown in Fig. 3, after being pressed against the web of crossed webs, the fiber pallet 15 appears to be more or less compressed within the areas of the trades, as shown in Fig. 21, while the fiber pallet maintains a relatively load condition within the areas of the spaces between the threads. the fabric, as shown mid 22, where some of the fibers amen Oro bragta to push through the fabric to the side ay delta, which is opposite the side, pa. which the fibers from the beginning were applied. The areas for the space threads form the predominant part in the area of the fabric, so that the loose condition of the fibrous garment in these areas gives a total effect on the blur and softness.

Kalandervalsarna kunna vara upphettade far att anyo aktivera termoplastklistret, da sadant anvandes, och del Sr i allmanhet lampligt, att de samverkande kalandervalsar, mellan vilka materialet fares, best& av en stalvale och en bomullsvals for att undvika sonderskarning ay de tvarlagda tradarna mid dessas skarningsstallen.

The calender rolls may be heated to activate the thermoplastic adhesive when used, and part Sr in general appropriate, that the cooperating calender rolls, between which the material is passed, consist of a steel roll and a cotton roll to avoid special cutting of the overlapping threads between their cutting stalls. Da en ay valsarna, I. ex. The roller 23, made of cotton construction, it is mandatory that the longitudinal members of the fabric 19 be on the side of the fabric which comes into contact with the cotton roller 23 (which is usually somewhat colder than the cooperating steel roller), so that said threads can be able to loosen the transverse threads 2 and the fiber pallet 15 from the roller 23, on which they, otherwise, could be attached. The fiber palaga and the non-stick trades 2 will prevent sticking to the adhesive-bearing, longitudinal trades on the second roller.

The thickness of the fiber pallet 15 can of course be varied with regard to the final anyam: Min: gen ay the material. This thickness tire drills on such variable factors as the speed of movement of the fabric web 19 through the fiber feeding zone, the speed at which the feed 16 is fed to the tear roller 17, and the thickness of the feed 16.

In some cases you need to joke, use glue on. the yarns of the fabric, but instead the yarns can be fitted with either the yarns or the batches of thermoplastic fibers, which. Such fibers can be reactivated by heat from a hot calender roll, e.g. the upper roll in the calender device 20, so that these activated fibers can provide adhesive bonds between the intersecting thread portions, and between the threads and the fiber garment. The fibrous garments also contain a small amount of thermoplastic fibers, which will also be activated as a result of heat from the calender device, s5. that adhesive joints are obtained between these thermoplastic fibers and other fibers in the layer and also between said thermoplastic fibers and adjacent threads of the wire web. Instead of using the habit of activating thermoplastic adhesives or thermoplastic fibers, you should use treatment with solvents or solvents. Likewise, suitable means may be used to activate or partially activate such thermoplastic fibers in the threads of a web 19, immediately before the web passes through the fiber drum 18, so that the fibers immediately become at least slightly solid at the bare web, when the fibers come into contact with this.

Detta material representerar en mycket billig cellulosakomponent av arket. An embodiment of a cellulosic sheet material consisting of the above-described material made of crossed threads is shown in Fig. 5, and this sheet material is in the nature of industrial wiping material to be used as a replacement for ordinary textile wiping pads. The material shown in Fig. 5 consists of a plurality of layers of crepe tissue paper or cotton wool, in the present case six layers 24. These layers are adhered to each other in a plurality of individual or discontinuous rows, or they may also be connected by pressure. within a plurality of small, independent and spaced-apart areas 25, which were more or less uniformly distributed over the entire area of the multilayer web of cotton wool. When used in the wiping industry, the wadding layers can be challenged with a fibrous pulp with a high content of unbleached fibers, as well as a fibrous pulp there formed into a very tufted, easily permeable tissue paper material with only a small water resistance. hog absorption formaga. This material represents a very inexpensive cellulosic component of the sheet.

Pade motsatta sidorna av den flerskiktiga vaddbanan finnas mycket tunna, icke vavda skikt 26 av fibrer, och utanfor dessa fiberskikt finnas nat eller banor 27 av korslagda tradar. Banorna 27 av korslagda tradar och skikten 26 ay fibrer tillforas i form ay banor av korslagda tradar med fiberpalagg av den i fig. 1 visade typen, och dessa kombinerade komponenter levereras sasom pa farhand for- made banor till hopmontering med bundna skikt av vadd.

Om det pa tradbanan anvanda klistret am ay termoplasfnatur, kan det aktiveras pa nytt genom anvandande av atminstone en upphettad kalandervals mid en. tillracklig temperatur f Or att lampligt paverka klistret. On the opposite sides of the multilayer batt, there are very thin, nonwoven layers 26 of fibers, and outside these fibrous layers are nat or webs 27 of crossed threads. The webs 27 of cross-threads and the layers 26 of fibers are supplied in the form of webs of cross-threads with fiber garments of the type shown in Fig. 1, and these combined components are supplied as manually formed webs for assembly with bonded layers of cotton wool. The fiber layers 26 drew • very thin, e.g. have a weight Mom range of 1,87.2 g / m2, are very permeable and allow the adhesive, which is applied to the tangent threads in the fabric component 27, to penetrate the fibrous layers to come into contact with the surfaces of the wadding, so that it adhesive bond is obtained between the wadding and the fabric webs and fibrous layers consisting of crossed trades. This adhesive connection melt = the wadding filling and the ay crossed threads consisting of the fabric pieces as well as the fibrous layer can be secured by applying relatively weak pressure, e.g. by passing the assembled materials between suitably spaced and suitably loaded calender rolls or press rolls. If it uses the adhesive on a thermoplastic nature on the treadmill, it can be reactivated by using at least one heated calender roll in the middle. sufficient temperature f Or to adversely affect the adhesive.

Klisterforbandet mellan tradbanan och huvuddelen av arket medelst Mister, som upp- bares av enbart de langsgaende tradarna, gi- ver en mycket saker forbindning. Ibland är det emellertid lampligt, att alla tradarna fas- tas genom klistring i huvudsak kontinuerligt langs sin langd for att i avsevard grad undamqija mojligheten av fiirekomsten av stal- len, dam tradarna kunna fastna pa grader ,och andra utsprang pa. en artikel, som avtorkas. For detta andamal kan klister spridas pa. sidorna ay den absorberande kroppen, omedelbart innan de fiberbelagda tradbanorna anbringas pa den absorberande kroppen, sa att de skyddande tradbanorna komma att fastklistras langs i huvudsak hela sin ldngd pa vaddkroppen. Saker fastsattning pa detta satt kraver paforing ay en tillracklig mangd klister for genomtrangning ay fiberytskikten 26, men, eftersont dessa ytskikt vanligen aro mycket tunna, sasom namnts, krava de icke pa-boring av en sadan mangd klister, som skulle Ora arket styvt eller hart. Dessutom kan klistret vara ay ett slag, som forblir varaktigt b8jligt, och manga sadana klistertyper finnas.

Klister kan paforas direkt pa ytan ay det av korslagda tradar bestaende tyget eller pa alla de &Alla", varav tyget framstalles, eller oeksa. kunna dessa tradar innehalla en lamplig halt bindefibrer, som mid lamplig behandling komma att foranluas pa den absorberande kroppen. I nagra fall kan Mister tryckas i linjer, punk-ter eller korta streck eller pd andra fran varandra skilda omraden pa ytorna av den absorberande kroppen eller pa de ay korslagda tradar bestaende banorna och bringas att genomtranga fiberpalagget for att astadkomma den. onskade forbindningen mellan den absorberande kroppen och bade det skyddande tracityget och fiberpalagget. The adhesive bond between the wire web and the main part of the sheet by means of Mister, which was supported only by the longitudinal wires, gives a very things connection. Sometimes, however, it is appropriate for all the wires to be fastened by gluing substantially continuously along their length in order to considerably obviate the possibility of the occurrence of the stables, in which the wires can be attached to degrees, and others protrude. an article, which is wiped. For this purpose, glue can be spread on. the sides of the absorbent body, immediately before the fiber-coated wire webs are applied to the absorbent body, so that the protective wire webs will be adhered along substantially their entire length to the batt body. Matters attached to this set require the application of a sufficient amount of adhesive to penetrate the fiber surface layers 26, but, since these surface layers are usually very thin, as mentioned, they do not require the drilling of such an amount of adhesive as would make the sheet rigid or hard. . In addition, the adhesive may be of a type which remains permanently flexible, and many such adhesive types exist. Instead of spraying the adhesive on the surfaces of the absorbent body, the adhesive can also be applied to this body by printing or in some other suitable way. Adhesives can be applied directly to the surface of the fabric consisting of crossed threads or to all the "All" from which the fabric is made, or so on. These threads may contain a suitable content of binder fibers, which by suitable treatment may be imparted to the absorbent body. In this case, Mister can be printed in lines, dots or short lines or in other spaced areas on the surfaces of the absorbent body or on the intersecting webs of existing webs and caused to penetrate the fibrous garment to provide the desired connection between the absorbent body. and both the protective tracity fabric and the fiber palette.

En modifikation ay anordningen i fig. 5 Askadliggores i fig. 5A, dar vaddskikt 24 aro forbundna medelst en serie langsriktade, fastklibbade bartradar 28. Dessa tradar foras genorn ett bad av klister eller belaggas pa annat lampligt satt med klister omedelbart fore deras matning till ldge mellan respektive intill varandra belagna vaddskikt 24.

A modification of the device of Fig. 5 is made ashes in Fig. 5A, where wadding layers 24 are connected by a series of longitudinal, glued barbed wires 28. These wires are passed through a bath of adhesive or otherwise conveniently coated with adhesive immediately prior to feeding them to the bed. between respective adjacent wadding layers 24. The adhesive can be applied to such trolleys in a quantity which is sufficient for the adhesive to penetrate the nearest adjacent and nearest dart following layers of the wadding body, said. that all the wadding layers are glued together. The adhesive coated wires 28 serve not only as an adhesive papering medium but also as reinforcing means for providing tensile strength of the absorbent tissue layer in the longitudinal direction of the llama. The outsides ay, the aggregate of the wadding layer can be tacked with wire cloth with fibrous garments, as shown in Fig. 5A, these tacking fabrics being glued to the outside of the wadding assembly in the manner described above.

I vissa fall kan forbandet mellan de olika elementen ay det beskrivna arket forbattras genom att i antingen tyartradarna .eller 'dugstradarna och i fiberpalagget infora termoplastfibrer, som kunna aktiveras pa nytt yid kalandrering eller annan behandling, som lampligt aktiyerar fibrerna pa nytt och bringa dem att bliva fastklistrade vid intilliggande komponenter ay arket. In some cases, the connection between the various elements of the sheet described can be improved by inserting into either the thyrar threads or the fabric threads and into the fiber pallet thermoplastic fibers, which can be reactivated by calendering or other treatment which conveniently reactivates the fibers and causes them to be glued to adjacent components of the sheet.

For att uppnd extra starkt f8rband mellan den absorberande kroppens -vaddskikt kan klister lampligt paforas ett 'eller flera ay de lure vaddskikten ay den absorberande kroppen, t. ex genom sprutning eller tryckning, varyid klistret pafores i sadan mangd, att det kommer att genomtranga de onskade yaddskikten for att hopklistra dem med yarandra och med skikt pa motsatta sidor av det eller de skikt, pa vilka klistret paftires. Den O.- lunda paforda klistermangden kan giyetvis regleras for att begransa den utstrackning, i vilken klistret kommer att genomtranga andra skikt, och pdforingen ax klister foretages lampligen pa ett sadant satt, att paforingen sker i ett flertal enskilda omraden utoyer skiktet i stallet for sasom en kontinuerlig hinna utover hela ytan av skiktet, varigenom forstyyning ay produkten forhindras. In order to obtain an extra strong connection between the wadding layer of the absorbent body, adhesive can be suitably applied to one or more of the lure wadding layers in the absorbent body, for example by spraying or printing, the adhesive being applied to such an extent that it will penetrate the desired the yadd layers to glue them together with yarandra and with layers on opposite sides of the layer or layers on which the glue is paftires. The amount of adhesive applied can be adjusted to limit the extent to which the adhesive will penetrate other layers, and the application of adhesive is suitably made in such a way that the application takes place in a number of individual areas outside the layer instead of such. a continuous film over the entire surface of the layer, thereby preventing distortion of the product.

Sasom ett alternatiy till anyandandet ax banor ax korslagda tradar pi utsidorna kan man begagna ett natoverdrag, som bestar ax en serie parallella, med mellanrum anordnade tradar 29 (fig. 6), som stracka sig tvars mot arkmaterialets langdriktning, och en se-Tie parallella, med mellanrum belagna klisterlinjer 30, som stracka sig i materialets langdriktning eller tyars mot de tvargaende tradarna. Tradarna kunna vara klisteroverdragna och darigenom fasta vid del absorberande vaddskiktet genom fibersldktet 26, eller ock- sAtradarna yara fria frin klister och forbundna rued det absorberande skiktet genom de tyargaende klisterlinjerna. As an alternative to the use of paths and paths of crossed threads on the outside, one can use a night cover, which consists of a series of parallel, spaced apart rows 29 (Fig. 6), which extend transversely to the longitudinal direction of the sheet material, and a se-Tie parallel , spaced adhesive lines 30, which extend in the longitudinal direction of the material or are stretched towards the transverse threads. The threads may be adhesive coated and thereby attached to the absorbent wadding layer through the fibrous layer 26, or the threads may be free of adhesive and bonded to the absorbent layer through the thick adhesive lines.

Likasa kan natOyerdraget besta ay en serie parallella, med mellanrum belagna tradar, seam stracka sig i arkets langdriktning, och en serie parallella, med mellanrum anordnade klisterlinjer, som stracka sig tyars mot tradarna. Similarly, the natOyerdraget may consist of a series of parallel, spaced-apart threads, seams extending in the longitudinal direction of the sheet, and a series of parallel, spaced-apart adhesive lines extending towards the threads.

I vissa fall kan det skyddande nat5yerdraget besta enbart ay med mellanrum belagna klisterlinjer, som stracka sig i en eller flera riktningar utoYer arkets yta. Ayenledes kan tryckning med klister begagnas i samband med natliknande tyger for att skydda ytorna ax arket. Sadan tryckning tjanar icke blott till att bilda ett natverk for att skydda underliggande material utan awn till att forbattra forbandet mellan tradnatet och det underliggande materialet. In some cases, the protective coating may only consist of spaced adhesive lines extending in one or more directions beyond the surface of the sheet. Similarly, printing with adhesive can be used in conjunction with night-like fabrics to protect the surfaces of the sheet. Such printing not only serves to form a network to protect the underlying material but also to improve the bond between the wire and the underlying material.

I andra fall kan natyerksytskyddet best& ay tre eller flera satser tradar, som stracka sig i olika vinklar tyars Over ytan ax arket for att darigenom giva okad draghallfasthet i ett motsyarande okat antal riktningar med motsyarande okning ay arkets stabilitet.

In other cases, the natural sheet protection may consist of three or more sets of threads, which extend at different angles and are stretched over the surface of the sheet to thereby provide increased tensile strength in a correspondingly increased number of directions with a corresponding increase in the stability of the sheet. Although it is usually most appropriate for the threads in the protective surface seams to be assembled in a normal, straight condition, there may be cases in which the threads can be paforas in a yag-shaped or ripple form for obtaining ay nat, which can be stretched to a limited extent in the thread. - the longing of the days.

A web 19 of fabric of crossed threads is guided through an operating zone of a mechanism which a - applies the desired layer of fibers to the crossed threads. the existing fabric, which can then be calendered by means of a suitable calender device 20 to provide the fibrous web 27 for the same side of the product.

En rulle 35, som bestar ay sex eller ett annat erforderligt antal silkespappersbanor eller flock och silkespapper, hopbundna pA det utvalda sattet, t. ex. sasom ,o-van beskrivits i — —7 samband med fig. 5, 6 och 7, Or lampligt uppburen, och den darifran ,aygivna banan 36 an- bringas oyanpa den pa ovan angivet satt tramstallda tackbanan 27. En annan rulle 38 av tackmaterial, som framstallts pa samma satt men lindats till en. forradsrulle, är limpligt uppburen, och den darifran kommande banan 39 anbringas ovan:pa vaddskiktet 36. Aggregatet utsattes darpa for tryck mellan ett par tryckvalsar 40, som kunna yara upphettade for att any° aktivera termoplastklister, som uppbares av de langsgaende tradarna av tyget i tackbanorna, for -att darig-enom astadkomma klisterforband mellan tackbanorna ,och det absorberande vaddskiktet pa det redan beskrivna Sattet.

A roll 35, consisting of six or another required number of webs of tissue or flock and tissue, bonded together in the selected manner, e.g. As described in connection with Figs. 5, 6 and 7, it is suitably supported, and the web 36 provided therefrom is placed on top of the trampled web 27 placed above. Another roll 38 of roofing material , produced in the same way but wound into one. supply roll, is glue-supported, and the resulting web 39 is applied above: to the batt layer 36. The assembly is subjected to pressure between a pair of pressure rollers 40, which may be heated to activate any thermoplastic adhesive carried by the longitudinal threads of the fabric in the gratings, to thereby provide adhesive bonds between the gratings, and the absorbent batt layer on the set already described. Others used to assemble the components Inuma is of course used, and the described method is only intended to be an exemplary embodiment.

En typisk metod for framstallning ay konstruktionen enligt fig. 6 bestar i att kontinuerligt mata tre vaddskikt till lage ovanpa varandra och astadkomma avsattning av det -erforderliga fiberytskiktet 26 pa den ena sidan av detta yaddaggregat. Klister eller bindefibrer i fiberytskiktet kunna lampligen begagnas fOr att forbinda fiberytskiktet med vaddaggregatet, om ett sadant fOrband onskas. Det fiberbelagda aggregatet, som betecknas med 41 i fig. 10, kan darph formas till ett ror runt dornen 5 av en korslaggningsapparat av sarnma natur, som den i samband med fig. 8 beskriyna. En lampligt listf5rsedd tryckvals 42 kan begagnas for att trycka klisterlinjer 30 pa ytan av det -aggregat, ph yilket tvartradar skola anbringas, och denna tryckning sker, medan aggregatet forblir i den flata formen, sasomTract, sasom antydes vid 43, kan darpa svepas runt roret, vilket darefter uppklippes, sasoin visas vid 44, mitt for de mot varandra stotande kanterna av banan 41. Det uppslitsade roret kan darpa utbredas till ett plant ark, sasom visas yid 45, och traden 43 kommer da att bilda tvartrad:arna 29 i fig. 6. For ett lamellerat ark med sex skikt silkespapper, sasom visas i fig. 6, bildar det treskiktiga, med fibrer belagda materialet °eh dess skyddsnat av tradar och klisterlinjer, framstallt ph det just beskrivna sattet, halften ay arkets tjocklek. Tva. sadana treskiktskonstruktioner matas sedan till lage ovanpa varandra, och klisteruppbarande tradar 28 matas mellan dessa konstruktioner for att fullborda hopmonteringen. For aggregat med fler eller lane an sex silkespappersskikt gores lamplig modifikation vid tillverkningen av de preliminara aggregaten och i antalet och 10- gena av skikten ay klisterharande tradar. Andra satt att hopmontera elementen kunna Oven begagnas. A typical method of manufacturing the structure of Fig. 6 consists in continuously feeding three batt layers to layer on top of each other and providing deposition of the required fiber surface layer 26 on one side of this surface aggregate. Adhesives or binder fibers in the fibrous surface layer can suitably be used to connect the fibrous surface layer to the calf assembly, if such a dressing is desired. The fiber-coated assembly, designated 41 in Fig. 10, can be formed into a tube around the mandrel 5 by a crossover of the same nature as described in connection with Fig. 8. A suitably striped pressure roller 42 may be used to print adhesive lines 30 on the surface of the assembly to which the transverse wire is to be applied, and this printing takes place while the assembly remains in the flat shape so that the tract, as indicated at 43, can be swept around the tube. , which is then cut, is shown at 44, opposite the abutting edges of the web 41. The slotted tube can be spread on a flat sheet, as shown yid 45, and the line 43 will then form the transverse line 29 in FIG. 6. For a laminated sheet of six layers of tissue paper, as shown in Fig. 6, the three-layer, fibrous material formed by its threads and adhesive lines, made in the manner just described, forms half the thickness of the sheet. Two. such three-layer constructions are then fed into layers on top of each other, and adhesive-bearing threads 28 are fed between these constructions to complete the assembly. For units with more or less than six layers of tissue paper, an appropriate modification is made in the manufacture of the preliminary units and in the number and 10-gen of the layers of adhesive threads. Others sat to assemble the elements can Oven be used.

Ett exempel ph vaddmaterial, framstallt enligt fig. 5A, har sex skikt oblekt krappsilkespapper, framstallt i huvudsak av oblekt tramassa, varvid de enskilda skikten hava en grundvikt a-v omkring 11,5 g/m2. De klisteruppliarande tradarna besta av mycket tunna, flerfibriga rayontradar med lag snodd, innehallande trettio fibrer med en snodd av om- kring 1 vary per cm, yarvid de erhallna tradarna hava en tjocklek av 75 den. Dessa tra- dar overdragas med poly-vinylacetatklister med .ovannamnda sammansattning. Vikten ay klistret p0 tradarna per m2 av tyget Or ran- kring 2,5-3,5 g. Det av korslagda tradar besthende tyget hade maskor med dimensionerna 2,5 X 5 mm och bestar av silkerayontradar med lOg snodd, bildande i huvudsak ratvinkel med varandra ph sa satt, att den ena satsen tradar stracker sig i den fardiga produktens langdriktning, medan den andra tradsatsen stracker sig i produktens tvarriktning. De tvargaende tradarna hava en grovlek ay 100 den. och innehalla fyrtio fibrer, medan de i maskinriktningen sig strackande tradarna hava en grovlek ay 75 den. och innehalla trettio rayonfibrer. An example ph wadding material, prepared according to Fig. 5A, has six layers of unbleached kraft paper, made mainly of unbleached pulp, the individual layers having a basis weight a-v of about 11.5 g / m2. The adhesive-expanding threads consist of very thin, multi-fiber rayon threads with a thin twist, containing thirty fibers with a twist of about 1 vary per cm, while the obtained threads have a thickness of 75. These threads are coated with poly-vinyl acetate adhesives of the above composition. The weight of the adhesive on the threads per m2 of the fabric is around 2.5-3.5 g. The fabric consisting of crossed threads had meshes with the dimensions 2.5 X 5 mm and consists of silk rayon threads with a 10 twist, forming mainly a steering angle. with each other ph so sat, that one set of trades extends in the longitudinal direction of the finished product, while the other set of trades extends in the transverse direction of the product. The two trades have a roughness of 100 den. and contain forty fibers, while the trades extending in the machine direction have a coarseness ay 75 den. and contain thirty rayon fibers.

Den sist beskrivna produkten har en tjocklek av omkring 0,75-1,00 mm och -Or trots sin lamellkonstruktion mycket -mjuk och bojlig och kan hopkramas till en sudd for aytorkning. Produktens mjukhet Or .sadan, att den kan bringas att mycket nara ansluta sig till oregelbundna ytor, skarpa horn och urtagningar. Materialet Or visserligen icke utfort av vattenfast eller i -van tillstand starkt papper men kan dock vatas och hopkramas till en avtorkningssudd liksom en aytorkningstyglapp saint darefter utbredas i flat form, torkas °eh anyandas pa nytt antingen torr eller vat. Det polyvinylacetatklister, som anvandes for hopfastning av de av korslagda tradar bestaende tygerna med ,aggregatet av vaddskikt Or i huvudsak fuktighetsfast och hindrar avlagsnande av tradbanor fran aggregatet av vaddskikt, sa att tradbanorna bilda varaktiga skyddsytoverdrag f Or vaddskikten. The last described product has a thickness of about 0.75-1.00 mm and -Or despite its lamella construction very -soft and flexible and can be squeezed into a wipe for surface drying. The softness of the product is such that it can be made to adhere very closely to irregular surfaces, sharp horns and recesses. Although the material is not made of waterproof or in some cases strong paper, it can still be watered and compressed into a wiping wipe as well as a cloth wiping cloth and then spread out in a flat form, dried or otherwise re-dried either wet or wet. The polyvinyl acetate adhesive used to bond the fabrics of the cross-linked yarns together with the batt layer aggregate is substantially moisture-resistant and prevents the removal of wire webs from the batt layer assembly, so that the wire webs form permanent protective surface coatings for the batt layers.

De sagda av korslagda tradar bestaende banorna giva icke blott avsevard draghallfasthet 'at pappersskiktaggregatet utan Oven ett ytskydd, som i avsevard grad hindrar brist- ningpappersskikten till foljd av gnid- el- ler torkverkan pa materialets yta. Tradarna i den av korslagda tradar bestaende banan tillsammans med de ,omedelbart darunder liggande, :lake vayda ytskikten av fibrer synas verka sasom skarmar, som hindra direkt beroring med det fOremal, som avtorkas, och pappersskikten, sa att de senare icke skadas I namirvard grad. Foljaktligen Or pappersskiktkomponenten effektivt skyddad mot skador genom rivning eller gnidning, som nor-malt Or mycket .nedbrytande pa mjukt silkespapper, sarskilt d papperet Or vatt. Denna vaddskyddsfunktion av de med fibrer bclagda, av korslagda tradar besthende banorna kan givetvis okas genom anyandning ay mindre glest, natliknande tyg eller tjockare tradar och tjockare fiberpalagg. De utskjutande 8— — tradhanorna eller skyddsnaten aro emellertid, da de framstallts pa ovan beskrivet salt och sarskilt (la de framstallts av flerfibriga tradar med liten snodd, tillräekligt mjuka °eh glesa f8r att de icke skola naranvart paverka det sammansatta materialets grepp. Foljaktligen hr greppet av det sammansatta materialet i huvudsak bestamt av stomm.en av pa varandra lagda skikt av krappad vadd. Denna stomme ãr mjuk, bojlig och sammanpressbar, sa ati den tilldelar produkten ina.nga av egensks.perna hos textilhanddukstyg och textiltorkduk. The said paths of crossed threads give not only considerable tensile strength to the paper layer assembly but also a surface protection which to a considerable extent prevents the bursting paper layers as a result of rubbing or drying action on the surface of the material. The trades in the web of crossed trades together with the, immediately below, lake vayda surface layers of fibers appear to act as scars, which prevent direct contact with the object being wiped, and the paper layers, so that the latter are not damaged to a degree. . Consequently, the paper layer component is effectively protected against damage by tearing or rubbing, which is normally very degrading on soft tissue, especially when the paper is wet. This wadding function of the webs covered with fibers, made of crimped threads can of course be increased by using less sparse, night-like fabric or thicker threads and thicker fiber garments. The protruding 8 - - thread cocks or protective seams, however, when they are made of the salt described above and especially (let them be made of multi-fiber threads with a small twist, are sufficiently soft and sparse so that they do not have to affect the grip of the composite material). the grip of the composite material is mainly determined by the body of superimposed layers of crimped wadding. This body is soft, flexible and compressible, so that it imparts to the product some of the properties of textile towel fabrics and textile cloths.

Fiberpalagget ãr ett mycket -viktigt element samband med skydd av vadden, i det att palagget liar benagenhet att bilda ett skikt i natur av en mycket genomtranglig skarm, som ar slat och avsevart mindre rivande an vadden. Denna skarm ãr sa pords, att den icke erbjuder namnvart motstand mot absorption av vatskor medelst den absorberande kroppen, oak den slata och icke rivande karaktaren av skarmen underlattar rorelse av materialet utover en yta vid avtorkning. Denna slathet dr emellertid icke av en sadan natur som en kontinuerlig hinna, att den stOr uppfangningen av smuts och annat frammande material fran en yta, varvid ma papekas, att de fataliga fibrerna I fiberpalagget, som giver he; genomtranglighet, Sa.S0111 redan aven antyder sadana mellanrum mellan fibrerna, att fickliknande utrymmen erhallas, i vilka smuts eller annat frammande material kan ansamlas under avtorkningsoperationen. The fibrous garment is a very important element in connection with the protection of the batt, in that the garment tends to form a layer in nature of a very permeable screen, which is smooth and considerably less tearing than the batt. This screen is said to offer no resistance to the absorption of water shoes by means of the absorbent body, nor does the smooth and non-tearing nature of the screen facilitate movement of the material beyond a surface during wiping. This smoothness, however, is not of such a nature as a continuous film, that it interferes with the capture of dirt and other foreign material from a surface, whereby it must be pointed out that the fatal fibers in the fiber garment, which gives he; permeability, Sa.S0111 already also suggests such gaps between the fibers, that pocket-like spaces are obtained, in which dirt or other foreign material can accumulate during the wiping operation.

For vissa avtorkningsandamal är det lampligt, att de tradar, sona anvandas i skyddsoverdragen, dro sa tunna, att de komma att ga sonder, am de haka fast vid en grad eller nagot annat utsprang i stallet for att dragas ut ur tyget till fOljd av r5relse av materialet tvars Over ett sadant utsprang.

For certain wiping purposes, it is appropriate that the threads used in the protective covers be drawn so thin that they come to give probes, if they are hooked to a degree or something else protrudes in the stable to be pulled out of the fabric as a result of movement. of the material across such a protrusion. The strength of the threads should for delta andamal of course be determined atnainstone partly in view of the strength of the adhesive bond present between the threads and the absorbent body, so that the adhesive bandage will retain the threads and cause the threads to give probes under the above conditions.

I stallet far wit utforma fiberbanan 15 pa tradtyget pa det i fig. 9 visade sattet kunna fibrerna pa fOrhand formas till en bana, t. ex. genom kardning eller genom andra metoder, varpa den fardigformade fiberbanan hopmonteras med de andra komponenterna pa nagot lampligt salt. Instead, the white web 15 can be formed on the wire fabric in the manner shown in Fig. 9, the fibers can be pre-formed into a web, e.g. by carding or by other methods, the prefabricated fibrous web is assembled with the other components on some suitable salt.

Prey visa, att i handeln forekommande, tyattade aytorkningsdukar av vayt tyg med dimensionerna 34 X 38 cm och vikten 38,8 g kunna absorbera ungefar 4,4 ganger sin vikt vatten, medan avtorkningslappar, som tillverkats pa det sist beskrivna sattet och hava dimensionerna 23,0 X 41 cm, kunna absor bera omkring 17 ganger sin vikt vatten. sa, dana a.vtorkningsdukar av textilvav skulle absorbera omkring .6 ganger sin vikt olja, medan den beskrivna produkten skulle absorbera omkring 10,8 ganger sin vikt olja. Prey show that commercially available thick fabric wipes with dimensions of 34 x 38 cm and a weight of 38.8 g can absorb approximately 4.4 times their weight of water, while wipes, made in the last described manner and having the dimensions 23 .0 X 41 cm, able to absorb about 17 times its weight of water. Thus, textile fabric wiping cloths would absorb about .6 times their weight of oil, while the product described would absorb about 10.8 times its weight of oil.

The described, improved, disposable, but not necessarily only once usable wipes are very advantageous in comparison with wipes air yavt fabric in question of softness and shape to snuggle after objects, and they act very much like cloth wipes. The surface properties of the material cause the product to slide much across a surface to be wiped, and the high absorbency and rapid absorption of paper cotton wool makes it possible for wiping means made of the described sheet material to catch and absorb water lint and dirt or other material. on a favorable salt in comparison with the effect of commercially available cloth wipes.
