Description
Vynález sa týká sposobu výroby samonosnej koženky s vlasovým povrchom na báze chlórovaných vinylových polymérov, pričom podmienky sú volené tak, že vrstva pasty chlórovaného vinylového polyméru, do ktorej sa vnášajú vlákenné častíce sa nanesie na vrstvu pasty chlórovaného vinylového polyméru, predželatinovanú na separačnej podložke a následné sa celý útvar želatinuje a oddělí od separačnej podložky.The present invention relates to a process for the manufacture of a self-supporting pile-based leatherette based on chlorinated vinyl polymers, wherein the conditions are selected such that a layer of chlorinated vinyl polymer paste into which the fiber particles are introduced is applied to the chlorinated vinyl polymer paste layer pregelatinized the whole body is gelatinized and separated from the separation pad.
Známe je, že pri plastických kožiach s velúrovým povrchom, ktoré majú vzhl'ad prírodnej velúrovej usne, tzv. semišů a podkladový materiál může byť napr. pletenina, vlákenné rúno, polyvinylchloridová folia, plech, tkanina alebo papier je možné velúrový efekt dosiahnúť pomocou chloridu sodného, cukru, uhličitanu amonného alebo iných vodorozpustných krystalických látok. (NSR pat 250 833, franc. pat. 1 118 687).It is known that in plastic leather with a velor surface, which has the appearance of natural velor leather, so-called. and the backing material may be e.g. knitted fabric, fiber fleece, polyvinyl chloride sheet, sheet, fabric or paper, the velor effect can be achieved with sodium chloride, sugar, ammonium carbonate or other water-soluble crystalline substances. (German Pat Pat 250 833, French Pat. 1 118 687).
Podlá CSSR pat. 91 689 sa velúrový efekt dosiahne sypáním kovových kryštálikov rovnomernej velkosti na povrch polyvinylchloridovej pasty. Po želatinách sa kovové častíce odstraňujú pomocou elektromagnetických alebo mechanických sil.According to CSSR pat. 91 689, a velor effect is achieved by pouring metal crystals of uniform size onto the surface of the polyvinyl chloride paste. In gelatin, the metal particles are removed by electromagnetic or mechanical forces.
Podobný efekt sa může dosiahnúť aj vzorováním za použitia valca, opatřeného brusnou vrstvou (franc. pat. 2 217 469).A similar effect can also be achieved by patterning using a roller provided with an abrasive layer (French Pat. 2,217,469).
USA pat. 4 303 706 popisuje spůsob výroby počesanej textilie semišového vzhfadu použitím počesanej textilie s velmi jemných vlákien, na ktoré sa aplikuje emulzia melamínovej živice, ktorá sa suší a tepelne spracuje za účelom vytvrdenia živice v textilii.US Pat. No. 4,303,706 discloses a method of making a combed suede look fabric using a combed very fine fiber fabric to which a melamine resin emulsion is applied which is dried and heat treated to cure the resin in the fabric.
Plastické koze s velúrovým povrchom je možné vytvořit aj povločkovaním, pričom na podkladový materiál, napr. tkaninu, papier, polyvinylchloridovú foliu, koženku je nanesená adhezívna vrstva, do ktorej sa vnesú vlákenné částice (NSR pat. 2 944 063, RD pat. 193 005, franc. pat. 2 207 212, franc. pat. 2 468 682, CSSR pat. 155 435).Plastic goats with a velor surface can also be formed by flocking. fabric, paper, polyvinyl chloride foil, leatherette is applied with an adhesive layer into which fiber particles are introduced (German Pat. No. 2,944,063, RD Pat. 193,005, French Pat. 2,207,212, French Pat. 2 468,682, CSSR No. 155,435).
ČSSR AO 191 373 sa týká syntetickej usne s velúrovou lícovou úpravou, ktorá sa získává spůsobom, že na jednostranné počesanú a postriženú bavlnenú tkaninu sa nanesie polyvinylchloridová pasta, ktorá sa želatinuje a brúsi.ČSSR AO 191 373 relates to a synthetic leather with a velor grain finish which is obtained by applying a polyvinyl chloride paste to a one-sided combed and cut cotton fabric, which is gelatinized and abraded.
Franc. pat. 1191200 popisuje nanášanie krátkých vlákien na rovinný útvar na báze kalandrovaného polyvlnylchloridu povrstveného „nespolymerizovanou“ polyvinylchloridovou pastou.Franc. pat. No. 1191200 describes the deposition of short fibers on a planar body based on calendered polyvinyl chloride coated with a "non-polymerized" polyvinyl chloride paste.
Československé AO č. 240 538 rieši spůsob výroby samonosnej koženky s vlasovým povrchom tak, že vlákenné častíce sa vnesú do jednej vrstvy pasty chlórovaného vinylového polyméru.Československé AO č. No. 240,538 solves a method of making a self-supporting pile leatherette by introducing the fiber particles into a single layer of a chlorinated vinyl polymer paste.
Nevýhodou uvedených spůsobov je, že pri tvorbě velúrového povrchu, prostredníctvom vodorozpustných látok je nutné zařadit stupeň prania, čím sa zvýšia nároky na zariadenie, technologická vodu a jej čistenie, regeneráciu solí a energetické nároky na sušenie.The disadvantage of the mentioned methods is that in the formation of the velor surface by means of water-soluble substances it is necessary to include the washing stage, which increases the demands on the equipment, process water and its purification, salt regeneration and energy requirements for drying.
Dosahovanie velúrového efektu pomocou kovových kryštálikov rovnomernej velkosti vyžaduje speciálně zariadenie na ich odstránenie a zachytávanie.Achieving the velor effect with metal crystals of uniform size requires specially a device for their removal and capture.
Pomocou brusného kotúča sa nedosahuje výrazného velúrového efektu.No significant velor effect is achieved with the grinding wheel.
Pri tvorbě velúrovej koženky metodou povločkovania sa v súčasnosti ako podklad pre povločkovanie používá polotovar alebo hotový výrobok, vyrobený v samostatnom procese, pričom za použitia plastov ako podkladových materiálov sa najčastejšie používajú kaučukové a polyuretanové lepidlá, ktoré spůsobujú hlavně ekologické problémy.In the formation of the velor leatherette by the flocking method, a semi-finished product or a finished product, manufactured in a separate process, is currently used as the flocking substrate, with rubber and polyurethane adhesives most frequently used as plastics, which cause mainly environmental problems.
Nevýhodou známých postupov, v ktorých sa vlákenné častíce ukotvujú do polyvinylchloridovej pasty, je najma získanie nejednoliateho útvaru a zmátkovitosť spůsobená rozměrovou nestabilitou polymérnych fólií. Tieto nedostatky sú odstránené samotnou vrstvou pasty, ale jej hrúbka je limitovaná Teologickými vlastnosťami a dížkou vlákenných častíc.A disadvantage of the known processes in which the fiber particles are anchored in the polyvinyl chloride paste is, in particular, the obtaining of a discrete formation and confusion caused by the dimensional instability of the polymeric films. These drawbacks are eliminated by the paste layer itself, but its thickness is limited by theological properties and the length of the fiber particles.
Uvedené a dalšie nevýhody rieši tento vynález, podlá ktorého samonosná koženka s vlasovým povrchom na báze chlórovaných vinylových polymérov vnášaním vlákenných častíc do povrchu pasty a následnou želatináciou robí tak, že vrstva pasty chlórovaného vinylového polyméru, do ktorej sa vnášajú vlákenné častíce sa nanesie na vrstvu pasty chlórovaného vinylového polyméru, predželatinovanú na separačnej podložke, s výhodou s priestorovým dezénom a následné sa celý útvar želatinuje a oddělí od separačnej podložky.These and other disadvantages are solved by the present invention according to which a self-supporting leatherette with a hair surface based on chlorinated vinyl polymers by introducing fiber particles into the paste surface and subsequent gelation makes the paste layer of the chlorinated vinyl polymer into which the fiber particles are introduced. % of the chlorinated vinyl polymer, pre-gelatinized on a release liner, preferably with a spatial pattern, and subsequently the entire formation is gelatinized and separated from the release liner.
Výhodou tohoto vynálezu je jeho 1'ahká technologická uskutečnitelnost a zabezpečenie pevného ukotvenia vlákenných častíc v chlórovanom vinylovom polymere. V případe použitia separačnej podložky s priestorovým dezénom sa zabezpečí vytvorenie útvaru, ktorý je obojstranne vzorovaný.The advantage of the present invention is its easy technological feasibility and ensuring a firm anchoring of the fiber particles in the chlorinated vinyl polymer. In the case of using a spatial tread separation pad, a formation is provided that is patterned on both sides.
Zvolený spůsob dvojvrstvovej polyvinylchloridovej základné pre vlasová koženku, dovoluje široké variácie v hrúbke vytvořeného útvaru, ako aj možnost rozdielneho zloženiá oboch polymérnych vrstiev, čím sa dosahuje variabilita vlastností celého útvaru.The chosen method of bilayer polyvinyl chloride base for pile leatherette allows wide variations in the thickness of the formed formation, as well as the possibility of different composition of the two polymer layers, thus achieving variability of the properties of the whole formation.
Okrem týchto· výhod má spůsob výroby podlá vynálezu bezpečnostně, ekologické a ekonomické přednosti voči doposíal1 používaným systémom.· In addition to these advantages, the process for making the present invention, safety, environmental and economic benefits to the hitherto used one system.
Ako separačnú podložku je možné použit’ papierovú podložku impregnovaná hydrofilnými pojidlami, s povrchovým poivlakom silikónovej emulzie ako separačného- činidla, impregnovaná tkaninu alebo ocelový nekonečný pás.A paper substrate impregnated with hydrophilic binders, with a surface coating of silicone emulsion as a release agent, an impregnated fabric or a steel endless belt may be used as a release liner.
Pod pojmom pasta chlórovaného vinylového polyméru sa rozumie viskózna suspenzia tvořená homopolymérmi a/alebo kopolymérmi, najma vinylchloridu, zmákčovadlami, plnivami a stabilizátormi, regulátormi viskozity a pod.By chlorinated vinyl polymer paste is meant a viscous suspension consisting of homopolymers and / or copolymers, in particular vinyl chloride, wetting agents, fillers and stabilizers, viscosity regulators and the like.
K príprave krátkých vlákenných častíc můžu byť použité všetky známe vlákna na báze prírodných a syntetických polymérov, ako aj anorganických vlákien, najmá polyamidových, viskózových, atď. Dížka aplikovaných častíc sa pohybuje v rozmedzí 0,1 až 15 mm<a jemnosť 0,05 až 80 dtex, len výnimočne je potřebné uplatnit rozměry.All known fibers based on natural and synthetic polymers as well as inorganic fibers, especially polyamide, viscose, etc., can be used to prepare short fiber particles. The length of the applied particles ranges from 0.1 to 15 mm <and the fineness is from 0.05 to 80 dtex, exceptionally the dimensions need to be applied.
Vlákenné částice je možné nanášať běžnými známými postupmi, ako napr. mechanicky, pneumaticky, elektrostaticky alebo ich kombináciou.The fibrous particles may be deposited by known methods, such as e.g. mechanically, pneumatically, electrostatically, or a combination thereof.
Pojmom želatinácia sa rozumie prevádzanie polyméru a zmákčovadla do· homogénneho stavu posobením tepla.By gelation is meant to bring the polymer and the wetting agent into a homogeneous state by heat absorption.
Vytvořený útvar po vnesení vlákenných častíc sa želatinuje pri už uvedenej teplote 135 až 220 °C po dobu 1 až 50 minút.The formed formation after the introduction of the fiber particles is gelatinized at the aforementioned temperature of 135 to 220 ° C for 1 to 50 minutes.
