Abstract

Superabsorbent material layers are thermofixed between tissue paper or nonwoven sheets. An absorbent material used during the transport by air of seafood, chemicals, flowers or other products, or in refuse containers, comprises a large amount of superabsorbent material thermofixed between tissue paper or nonwoven sheets, forming a very thin material with a high absorption capacity in relation to the material thickness and weight. Conventional cold or hot nip pressing techniques are used to laminate the layers together. TEXTILES AND PAPER - The superabsorbent layers contain 4-50 (10-20) wt.% binder chosen from polyethylene, polypropylene, EVA or other modified plastics, thermoplastic starches, various synthetic fibres or hot-melt adhesives. Layers of superabsorbent layers are placed between two layers of 100% cellulose to control the spread of liquid between these superabsorbent layers.

Description

.lnl 512 624 Z Uppfinningen beskrivs närmare nedan av bifogad skiss, vilken i fig. 1 visar en schematisk perspektivvy av en absorbent d.v.s. fyra absorbentmaterial lag med omslag av fibertyg eller plast. Omslaget är till för att hålla ihop absorbenten när den stora vätskemängden absorberats. The invention is described in more detail below in the accompanying sketch, which in Fig. 1 shows a schematic perspective view of an absorbent, i.e. four layers of absorbent material with covers of non-woven fabric or plastic. The cover is for holding the absorbent together when the large amount of liquid has been absorbed.

En av teknikerna bygger pà att blanda 40-300 gram/m2 superabsorbenter med ett bindemedel. Blandningen fördelas jämt med ex. en vals på den löpande banan och termofixeras tillsammans med superabsorbenten mellan tvä tissueark,pappersark eller fibertygsark med en hastighet på upp till 400m/min, företrädesvis 10-200 N/min. Bindemedlet består av ett pulver med tennoplastiska egenskaper ex. polyeten, polypropylen, EVA, modifierade plaster eller termoplastisk stärkelse.One of the techniques is based on mixing 40-300 grams / m2 superabsorbents with a binder. The mixture is distributed evenly with e.g. a roller on the running web and is thermofixed together with the superabsorbent between two tissue sheets, paper sheets or non-woven fabric sheets at a speed of up to 400 m / min, preferably 10-200 N / min. The binder consists of a powder with tinoplastic properties e.g. polyethylene, polypropylene, EVA, modified plastics or thermoplastic starch.

Inblandningen av detta bindemedel sker normalt med en andel av 4-50% av superabsorbentvikten, företrädesvis 10-20%. Termofixeringen sker i ett valsnyp med ett linjetryck av 10-l0ON/mm företrädesvis 25-45N/mm med en material-temperatur av 40-220 grader Celsius beroende pà typ av bindemedel.The admixture of this binder normally takes place in a proportion of 4-50% of the superabsorbent weight, preferably 10-20%. The thermofixing takes place in a roll nip with a line pressure of 10-100N / mm, preferably 25-45N / mm with a material temperature of 40-220 degrees Celsius depending on the type of binder.

Den andra tekniken bygger på att tissuen, papperet eller fibertyget innehåller syntetfibrer med en inblandning av 5-50 % företrädesvis 10-20 % som ett bindemedel för superabsorbenten, vilket innebär att superabsorbenten allena eller med en blandning av termoplastisk pulver som ovan nämnts och som fördelas pà den löpande banan och termofixeras som ovan nämnts.The second technique is based on the tissue, paper or nonwoven fabric containing synthetic fibers with a mixture of 5-50%, preferably 10-20% as a binder for the superabsorbent, which means that the superabsorbent alone or with a mixture of thermoplastic powder as mentioned above and distributed on the running track and thermofixed as mentioned above.

Den tredje tekniken bygger på att tissuen, papperet eller fibertyget täckes med en hotmeltfilm pà ena eller båda arken och med en andel av 4-50 % företrädesvis 10-20% av superabsorbentvikten,pà underarket med hotmeltfilmen fördelas superabsorbenten med en ytvikt av 40-300 gram/m2 och arken föres samman med superabsorbenten och bindemedlet mellan arken. Materialet kallpräglas samman i ett valsnyp eller varmpräglas med en materialtemperatur av 40-220 C i ett värmenyp med ovan nämnda linjetryck. Dessa tre tekniker framställer ett material som här kallas för absorbentmaterial (1)The third technique is based on the tissue, paper or non-woven fabric being covered with a hot melt film on one or both sheets and with a proportion of 4-50%, preferably 10-20% of the superabsorbent weight, on the substrate of the hot melt film the superabsorbent is distributed with a basis weight of 40-300 grams / m2 and the sheets are brought together with the superabsorbent and the binder between the sheets. The material is cold embossed together in a roll nip or hot embossed with a material temperature of 40-220 C in a heat nip with the above-mentioned line pressure. These three techniques produce a material known here as absorbent material (1)
