Pätová vložka pre obuvnícky priemyselHeel lining for the footwear industry
Oblasť technikyTechnical field
Vynález sa týka pätovej vložky pre obuvnícky priemysel a spôsobu jej výroby.BACKGROUND OF THE INVENTION The present invention relates to a heel pad for the footwear industry and to a process for its manufacture.
Doterajší stav technikyBACKGROUND OF THE INVENTION
V obuvníckom priemysle sa na vyloženie zadnej časti topánky, takzvanej pätovej ochrany, používajú materiály, ktoré sú obzvlášť odolné proti oteru. Tieto materiály majú jednak zachytávať sily, ktoré pôsobia prostredníctvom nohy na topánku, predovšetkým pri odťahovacom pohybe v pozdĺžnom smere, jednak musia odolávať trecím silám, ktoré sú pri chodení v topánke vyvolávané nohou, pohybujúcou sa aspoň čiastočne nahor a dole. Aby sa pri odťahovacom pohybe zabránilo nechcenému vykĺznutiu z topánky, tak sa ako pätová vložka používa tradične hrubá koža alebo koža z divočiny, ktorá trecím stykom s nohou alebo s pančuchou nositeľa zabraňuje vykĺznutiu nohy z topánky.In the shoe industry, materials that are particularly abrasion-resistant are used to lining the back of the shoe, the so-called heel protection. On the one hand, these materials are intended to absorb the forces exerted by the foot on the shoe, in particular during the pulling movement in the longitudinal direction, and on the other hand to resist the frictional forces exerted by the foot moving at least partially up and down. In order to prevent unwanted slipping out of the shoe during the pulling movement, a traditional thick leather or wild leather is used as the heel insert, which by frictional contact with the wearer's foot or stocking prevents slipping of the foot from the shoe.
Okrem pätových vložiek, zhotovených z prírodných materiálov, sa tiež používajú syntetické materiály. Týmito syntetickými materiálmi sú vpichované rúnové textílie, ktoré sa zhotovujú suchou cestou pomocou mykania z polyesterových, viskóznych, polyamidových, polypropylénových vlákien, poprípade zmesí týchto vlákien. Na tento účel sa pokladajú vláknové flóry s plošnou hmotnosťou až 800 g/m^, a intenzívnym vpichávaním sa mechanicky spevňujú. Už samotný tento krok je veľmi náročný na čas, a tým je relatívne drahý. Obvykle nasleduje zrážanie vpichovanej rúnovej textílie horúcim vzduchom alebo parou, ktoré vedie ku zhusťovaniu materiálu, ako aj k ďalšiemu spevňovaniu s ohľadom na nastavenie hustoty, vyžadovanej na daný účel použitia. Aby sa dosiahli potrebné pevnostné parametre, ako je odolnosť vpichovanej rúnovej textílie proti vytrhnutiu a proti ďalšiemu trhaniu, tak sa táto impregnuje pomocou teplom koagulovateľnej disperzie latexového spojiva, ako je styrén - butadién kaučuk (styrény - butadiény - gumy - SRB), alebo nitril - butadién - kaučuk (nitrily - butadiény - gumy - NBR), a následne suší. Podiel latexu je cca 30 až 60 hmotnostných % hmotnosti impregnovanej rúnovej textílie. Takto pripravený materiál sa štiepi do dvoch až štyroch tenších vrstiev. Tento štiepiaci spôsob bol pre rúnové textílie prevzatý z kožiarskeho priemyslu, aby sa zvýšila produktivita pri výrobe rúnovej textílie. Rozštiepené produkty sa môžu za účelom vyrovnania povrchu a zlepšenia optickej konečnej úpravy ešte pribrúsiť. Na záver sa na jednu z oboch strán nanáša tavné lepidlo, aby sa zjednodušilo ďalšie spracovanie. Nevýhodou u dosiaľ používanej syntetickej pätovej vložky sú predovšetkým veľmi rozdielne pevnostné hodnoty v pozdĺžnom a priečnom smere, strata pevnosti vznikajúca štiepením zväzkov vlákien usporiadaných vpichovaním zvislo, a tiež nerovnomernosti jednotlivých vrstiev, podmienené s ohľadom na stranu vpichu a vypichnutia.In addition to the heel inserts made of natural materials, synthetic materials are also used. These synthetic materials are needlepunched nonwoven fabrics which are made dry by carding from polyester, viscous, polyamide, polypropylene fibers or blends thereof. For this purpose, fiber flora with a basis weight of up to 800 g / m @ 2 are laid and mechanically consolidated by intensive stitching. This step alone is very time consuming and thus relatively expensive. Usually there is precipitation of the needled nonwoven fabric with hot air or steam, which leads to densification of the material as well as further consolidation with respect to the density adjustment required for the intended use. In order to achieve the necessary strength parameters, such as the tear-off and further tear resistance of the needled nonwoven fabric, it is impregnated with a thermally coagulable dispersion of a latex binder such as styrene-butadiene rubber (styrene-butadiene-rubber-SRB) or nitrile- butadiene - rubber (nitriles - butadienes - rubbers - NBR), and then dried. The latex content is about 30 to 60% by weight of the impregnated nonwoven fabric. The material thus prepared is cleaved into two to four thinner layers. This cleavage process has been taken from the leather industry for nonwoven fabrics to increase productivity in the nonwoven fabrics. The split products can be further ground to even the surface and improve the optical finishing. Finally, a hot melt adhesive is applied to one of the two sides to facilitate further processing. The disadvantages of the synthetic heel hitherto used are, in particular, very different strength values in the longitudinal and transverse directions, the loss of strength resulting from the splitting of the fiber bundles arranged vertically by stitching, and also the unevenness of the individual layers, depending on the stitching and stabbing side.
Vynález si stanovil úlohu vytvoriť pätovú vložku pre obuvnícky priemysel, ktorá má pri plošných hmotnostiach 180 až 350 g/m^ pevnosť proti vytrhnutiu a proti ďalšiemu trhaniu, a to ako v pozdĺžnom, tak i v priečnom smere, > 15 N.SUMMARY OF THE INVENTION The object of the present invention is to provide a heel pad for the shoe industry which has a tear and tear strength of 180 to 350 g / m @ 2 in both the longitudinal and transverse directions, > 15 N.
Vynález si ďalej stanovil úlohu vytvoriť spôsob, ktorý je obzvlášť vhodný na výrobu takej pätovej vložky.The invention has further set itself the object of providing a method which is particularly suitable for the production of such a pad.
Podstata vynálezuSUMMARY OF THE INVENTION
Podľa vynálezu sa táto úloha rieši pätovou vložkou, ktorá pozostáva z rúnovej textílie, impregnovanej polymérom, o plošnej hmotnosti 180 až 350 g/m2 a pevnosti proti ďalšiemu trhaniu ako v pozdĺžnom, tak aj priečnom smere^ 15 N, pričom rúnová textília pozostáva z taveniny zvláknených, aerodynamický predĺžených a bezprostredne na rúno založených viaczložkových nekonečných filamentov s titrom < 2 dtex, a viaczložkové nekonečné filamenty sú po predbežnom spevnení rozštiepené a spevnené z aspoň 90 % na supermikro nekonečné filamenty s titrom < 0,2 dtex. Tieto pätové vložky majú vysoké ťahové zaťažiteľnosti a odolnosti proti oteru pri nepatrných plošných hmotnostiach.According to the invention, this object is achieved by a heel insert comprising a polymer-impregnated nonwoven fabric having a basis weight of 180 to 350 g / m 2 and a tear strength of both longitudinal and transverse direction 15 15 N, wherein the nonwoven fabric consists of a melt spinned, aerodynamic elongated and immediately web-based multi-component filaments with a titre of < 2 dtex, and multi-component filaments with a pre-consolidation are split and consolidated to at least 90% to supermicro filaments with a titre of < 0.2 dtex. These heel inserts have high tensile load and abrasion resistance at low basis weights.
Výhodne je pätovou vložkou taká, u ktorej je viaczložkovým nekonečným filamentom dvojzložkový nekonečný filament z dvoch nekompatibilných polymérov, predovšetkým polyesteru a polyamidu. Viaczložkový nekonečný filament má tým dobrú štiepateľnosť a veľmi priaznivý pomer pevnosti k plošnej hmotnosti.Preferably, the heel pad is one in which the multi-component filament is a two-component filament of two incompatible polymers, in particular polyester and polyamide. The multi-component endless filament thus has good cleavability and a very favorable ratio of strength to basis weight.
Výhodne je pätovou vložkou taká, u ktorej je podiel polyesteru vo viaczložkovom nekonečnom filamente vyšší než podiel polyamidu, predovšetkým je v rozsahu pomeru hmotností podielu polyesteru ku podielu polyamidu 1,1 : 1 až 3:1. Pätové vložky tým majú veľmi textilný ohmat a dobrú odolnosť proti starnutiu.Preferably, the heel pad is one in which the proportion of polyester in the multicomponent filament is higher than the proportion of polyamide, particularly in the range of the weight ratio of polyester to polyamide of 1.1: 1 to 3: 1. The heel inserts thus have a very textile feel and good aging resistance.
Obzvlášť výhodnou je pätová vložka, u ktorej majú viaczložkové nekonečné filamenty prierez s pomarančovou multisegmentovou štruktúrou, pričom segmenty obsahujú striedavo vždy jeden z oboch nekompatibilných polymérov.A heel insert is particularly preferred, in which the multi-component endless filaments have a cross section with an orange multisegment structure, wherein the segments each alternately comprise one of the two incompatible polymers.
Výhodne je pätovou vložkou taká, u ktorej je rúnová textília, vytvorená z viaczložkových nekonečných filamentov, za účelom predbežného spevnenia najprv kalandrovaná. Materiál má tým veľmi dobrú rovnomernosť v hrúbke.Preferably, the heel pad is one in which the nonwoven fabric is formed from multi-component continuous filaments for first consolidation to be calendered. The material thus has a very good uniformity in thickness.
Obzvlášť výhodná je ďalej pätová vložka, u ktorej aspoň jeden z nekompatibilných polymérov, vytvárajúcich viaczložkový nekonečný filament, obsahuje prísady, ako sú pigmenty farieb, trvalé pôsobiace antistatiká a/alebo prímesi ovplyvňujúce hydrofilné alebo hydrofóbne vlastnosti, v množstvách až 15 hmotnostných %. Pätová vložka tým môže byť vzhľadom na svoju svetelnú stálosť, sklon k statickému nabíjaniu, možnosti zvárania, poprípade odolnosti proti vlhkosti, pozitívne ovplyvňovaná. Ďalej umožňuje pridanie pigmentov farieb do zvlákňovacej hmoty vytvorenie hlbších a proti oteru odolnejších farieb.Furthermore, a heel insert in which at least one of the incompatible polymers constituting the multi-component continuous filament comprises additives such as color pigments, sustained-acting antistatic agents and / or additives affecting hydrophilic or hydrophobic properties in amounts of up to 15% by weight is particularly preferred. Due to its light stability, tendency to static charging, welding possibilities or moisture resistance, the heel insert can thus be positively influenced. Furthermore, the addition of color pigments to the spinning material allows the formation of deeper and abrasion resistant colors.
Obzvlášť výhodná je ďalej pätová vložka, u ktorej nie je viaczložkový nekonečný filament zriasený, pretože tým je zaistený textilný ohmat, vyplývajúci z dobrej štiepateľnosti do supermikro nekonečných filamentov.Furthermore, a heel insert is particularly advantageous in which the multi-component endless filament is not shirred because this provides a textile feel resulting from good cleavability into super-micro endless filaments.
Obzvlášť výhodná je podľa vynálezu pätová vložka, u ktorej je rúnová textília s 20 až 50 hmotnostnými % polyméru, vztiahnuté na východiskovú hmotnosť rúnovej textílie, impregnovaná. Pätová vložka má pri porovnateľných stupňoch impregnácie oproti známym syntetickým materiálom pre pätové vložky lepšie pevnostné vlastnosti.According to the invention, a heel insert is particularly preferred, in which a web of 20 to 50% by weight of polymer, based on the starting weight of the web, is impregnated. The heel liner has better strength properties at comparable impregnation degrees compared to known synthetic liner materials.
Výhodne je pätovou vložkou taká, u ktorej je jedna zo strán vybavená povlakom tavného lepidla. Taký materiál je obzvlášť vhodný na ďalšie spracovanie na automatických strojoch.Preferably, the heel insert is one in which one of the sides is provided with a hot melt adhesive coating. Such a material is particularly suitable for further processing on automatic machines.
Spôsob výroby pätovej vložky podľa vynálezu spočíva v tom, že sa viaczložkové nekonečné filamenty zvlákňujú z taveniny, aerodynamický sa predlžujú a bezprostredne skladajú na rúno, pomocou predchádzajúceho valcovania alebo vpichovania sa vykonáva predbežné spevnenie, a rúnová textília sa spevňuje vysokotlakovými lúčmi fluida, a súčasne sa štiepi na supermikro nekonečné filamenty s titrom < 0,2 dtex, a následne sa impregnuje polymérom. Takto vytvorené produkty sú vzhľadom na svoju pevnostnú zaťažiteľnosť veľmi rovnomerné, pretože je v produkte vytvorené veľmi izotropné rozdelenie nití. Produkty nevykazujú žiadny sklon k delaminácii a majú vysoké hodnoty modulu, ako aj pevnosti proti ďalšiemu trhaniu.The method of manufacture of a heel insert according to the invention is characterized in that the multi-component endless filaments are melt-spun, aerodynamically elongated and immediately folded onto a web, pre-consolidation is performed by prior rolling or needling, and the web is reinforced by high pressure and it cleaves into supermicro endless filaments with a titre <0.2 dtex, and is subsequently impregnated with a polymer. The products formed in this way are very uniform due to their strength, because a very isotropic distribution of the yarns is produced in the product. The products show no tendency to delamination and have high modulus values as well as tear strength.
Ďalšie výhodné uskutočnenie spôsobu spočíva v tom, že sa spevnenie a štiepenie viaczložkových nekonečných filamentov vykonáva tak, že sa vopred spevnená rúnová textília viackrát striedavo z oboch strán ostrieka vysokotlakovými vodnými lúčmi. Tento spôsob spevňovania a štiepenia viaczložkových nekonečných filamentov vedie k veľmi hustým rúnovým textíliám s hladkými povrchmi.A further advantageous embodiment of the method is that the consolidation and splitting of the multicomponent filaments is carried out by spraying the pre-consolidated fleece fabric several times alternately on both sides with high-pressure water jets. This method of strengthening and splitting multicomponent filaments leads to very dense fleece fabrics with smooth surfaces.
Výhodne sa spevňovanie a štiepenie viaczložkového nekonečného filamentu vykonáva na agregáte s rotujúcimi sitovými bubnami. Tento druh agregátov umožňuje konštrukciu veľmi kompaktných zariadení.Preferably, consolidation and cleavage of the multi-component continuous filament is carried out on an aggregate with rotating screen drums. This type of aggregate allows the construction of very compact devices.
Obzvlášť výhodným spôsobom sa vykonáva impregnácia rúna, rozštiepeného a spevneného prevažne na supermikro nekonečné filamenty, s vodnou polyuretánovou latexovou disperziou alebo latexovou disperziou NBR. Tým sa odstránia zvyšky riedidiel, a impregnácia polymérom sa vykonáva spôsobom, obzvlášť priaznivým pre okolité prostredie.A particularly preferred method is to impregnate the web, split and consolidated predominantly into supermicro endless filaments, with an aqueous polyurethane latex dispersion or a NBR latex dispersion. This removes diluent residues, and impregnates with the polymer in a particularly environmentally friendly manner.
Výhodným spôsobom sa impregnovaný materiál podrobuje ešte ďalšiemu spracovaniu brúsením alebo zatlačovaním. Vplyvom týchto opatrení sa môže povaha povrchu a ohmat vytvoreného materiálu ešte zlepšiť. Vplyvom mikrofilamentov, obsiahnutých v štruktúre, vzniká pritom obzvlášť jemný a ušľachtilý, koži z divočiny podobný povrch, ktorý sa veľmi blíži prírodnej koži.Preferably, the impregnated material is subjected to further processing by grinding or pressing. As a result of these measures, the nature of the surface and the feel of the material formed can be further improved. Due to the microfilaments contained in the structure, a particularly fine and noble, wild-skin-like surface is obtained which is very close to natural skin.
Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
PríkladExample
Z viaczložkového nekonečného filamentu, pozostávajúceho z 65 hmotnostných % polyetyléntereftalátu a 35 hmotnostných % polyhexametyléndypamidu sa zhotovuje flór rúnovej textílie o plošnej hmotnosti cca 160 g/m^. Východiskové filamenty majú titer cca 1,8 dtex a pozostávajú zo 16 segmentov, pričom sa polyester a polyamidové segmenty striedajú ako pomarančové štrbiny okolo stredovej osi. Z taveniny zvláknené viaczložkové nekonečné filamenty sa aerodynamický predlžujú a nepravidelne skladajú na páse. Takto vytvorený flór rúnovej textílie sa privádza k počiatočnému kalandrovaniu pri teplotách cca 95 °C a tlaku cca 10 MPa (100 bar). Po mechanickom predbežnom spevnení pomocou vpichovania prebieha spracovanie vodným lúčom pri vodnom tlaku cca 10 MPa (100 bar). Následne sa vykonáva štiepenie viaczložkových nekonečných filamentov na supermikro nekonečné filamenty s titrom cca 0,1 dtex, a spevňovanie rúnovej textílie pomocou vysokotlakových vodných lúčov. Spracovanie sa vykonáva vždy dvakrát z oboch strán pri tlakoch vody 25 až 30 MPa (250 až 300 bar) a na sitových podkladoch s 60 až 100 mesh veľkosťou ôk. Rúno sa následne suší a podrobuje impregnácii polymérom pomocou spracovania za sucha do mokra s latexom NBR. Nanáša sa cca 125 hmotnostných % NBR, vztiahnuté na východiskovú hmotnosť rúnovej textílie, a fixuje sušením priA multi-component continuous filament consisting of 65% by weight of polyethylene terephthalate and 35% by weight of polyhexamethylenedypamide is used to produce a fleece web of about 160 g / m @ 2. The starting filaments have a titer of about 1.8 dtex and consist of 16 segments, with polyester and polyamide segments alternating as orange slits around the central axis. The melt-spun multicomponent filaments are aerodynamically elongated and folded irregularly on the belt. The fleece fabric formed in this way is fed to an initial calendering at a temperature of about 95 ° C and a pressure of about 10 MPa (100 bar). After mechanical pre-consolidation by needle punching, the water jet treatment is carried out at an aqueous pressure of about 10 MPa (100 bar). Subsequently, the cleavage of the multi-component filaments into supermicro-filaments with a titre of about 0.1 dtex is performed, and the nonwoven fabric is consolidated using high-pressure water rays. The treatment is carried out twice on both sides at water pressures of 25 to 30 MPa (250 to 300 bar) and on sieves with a mesh of 60 to 100 mesh. The web is then dried and subjected to polymer impregnation by dry-wet treatment with NBR latex. Approximately 125% by weight of NBR, based on the starting weight of the nonwoven fabric, is applied and fixed by drying at
180 °C. Po prebrúsení sa získa pätová vložka o hmotnosti 260 g/m2 a hrúbke 0,75 mm.Mp 180 ° C. After regrinding, a heel pad of 260 g / m 2 and a thickness of 0.75 mm is obtained.
Porovnávací príkladComparative example
Z polyesterových a polypropylénových strižových vlákien sa intenzívnym vpichovaním vytvára rúnová textília a impregnuje pomocou NBR. Vplyvom štiepenia sa získa pätová vložka o plošnej hmotnosti 320 g/m2 a hrúbke 0,85 mm.Polyester and polypropylene staple fibers are used to form a fleece fabric by intensive stitching and impregnated with NBR. Due to the cleavage, a heel pad having a basis weight of 320 g / m @ 2 and a thickness of 0.85 mm is obtained.
Porovnanie pevnostných hodnôt a odolnosti proti oteru je zhrnuté v nasledujúcej tabuľke 1. Odolnosť proti oteru bola pritom zisťovaná spôsobom, že sa do rotačnej upínacej hlavy upne skúšobné teleso o priemere 90 mm, a zaťažuje brusným tlakom 2,8 N/cm2. Uhol natočenia upínacej hlavy je 50 stupňov. Skúšobná vzorka sa testuje proti brúsnemu prvku, ktorý má na svojom povrchu kosoštvorce. Meracia skúšobná vzorka sa zmočí vodou a vystaví cyklickému pohybu sem a tam, pričom jeden brúsny cyklus pozostává z 300 pohybov sem a tam, na ktoré nadväzuje vizuálne zhodnotenie na základe známkovacej predlohy.A comparison of the strength values and the abrasion resistance is summarized in the following Table 1. The abrasion resistance was determined by clamping a test piece with a diameter of 90 mm into the rotary clamping head and applying a grinding pressure of 2.8 N / cm 2. The angle of rotation of the clamping head is 50 degrees. The test specimen is tested against an abrasive element having diamonds on its surface. The test sample is wetted with water and subjected to a cyclic back and forth movement, with one grinding cycle consisting of 300 back and forth movements followed by visual evaluation based on the mark pattern.
