Definitions

• the invention relates to the use of a nonwoven fabric as heel lining for the shoe industry.
• the shoe industry uses particularly abrasion-resistant materials for the Lining the rear part of a shoe, the so-called heel cap, used.
• these materials are intended to absorb the forces caused by the foot on the shoe, especially when rolling in the longitudinal direction on the other hand, they must be subjected to the frictional forces caused by which at least partially moved up and down when walking in the shoe Be called forth, withstand.
• To prevent it from slipping out unintentionally Avoiding out of the shoe during the rolling motion is traditionally one rough or suede-like material used as heel lining, which by a frictional connection with the foot or the stocking of the wearer Prevents slipping out of the shoe.
• a heat-coagulable latex binder dispersion such as styrene-butadiene rubber (styrene-butadiene rubber - SBR) or nitrile-butadiene rubber (nitrile-butadiene rubber). NBR) impregnated and then dried.
• the latex content is approx. 30 to 60% by weight of the impregnated nonwoven weight.
• the material prepared in this way is split into two to four thinner layers. This splitting process was adopted from the leather industry for nonwovens in order to increase productivity in the production of nonwovens.
• the fission products can be sanded to make the surface even and to improve the optical finish.
• a hot melt adhesive is applied to one of the two sides to simplify further processing. Disadvantages of the synthetic heel lining used up to now are, above all, the very different strength values in the longitudinal and transverse directions, the loss of strength due to the splitting of the fiber bundle arranged vertically from needling, and the unevenness of the individual layers with regard to the insertion and removal side.
• Nonwovens with a basis weight of 5 to 600 g / m 2 are known from document US Pat. No. 5,899,785, which consist of continuous composite filaments which can be separated along their longitudinal direction, have a fiber titer of 0.3 to 10 dtex and consist of consist of at least three filaments, which are formed from at least two different polymer materials, each filament having a titer between 0.005 and 2 dtex and the ratio between the cross-sectional area of a filament and the total cross-sectional area of the uniform composite filaments between 0.5 and 90% lies, wherein the composite filaments have a tubular cavity in the direction of their central axis.
• Such nonwovens should be suitable for the production of intermediate layers of shoes or the production of synthetic leather.
• the object of the invention is to use a heel lining for the shoe industry which, at grammages from 180 to 350 g / m 2 , has tearing and tear strength in the longitudinal and transverse directions> 15 N.
• the object is achieved by using a nonwoven fabric consisting of a nonwoven fabric impregnated with a polymer and having a basis weight of 180 to 350 g / m 2 and tear strength in both the longitudinal and transverse directions> 15 N, the nonwoven fabric being made from melt-spun, aerodynamically stretched and multicomponent filaments with a titer of ⁇ 2 dtex deposited directly to a nonwoven and the multicomponent filaments after pre-consolidation are at least 90% split and consolidated into super micro continuous filaments with a titer of ⁇ 0.2 dtex and in which the nonwoven fabric with 20 up to 50% by weight of a polymer, based on the initial weight of the nonwoven, is impregnated as heel lining for the shoe industry.
• the heel lining is preferably one in which the multicomponent continuous filament a bicomponent continuous filament made of two incompatible Polymers, especially a polyester and a polyamide.
• the Multicomponent continuous filament therefore has good cleavage and very favorable ratio of strength to basis weight.
• the heel lining is preferably one in which the polyester content is in Multi-component continuous filament higher than the polyamide content, in particular in the range of the weight ratio of polyester to polyamide 1.1: 1 to 3: 1.
• the heel lining has a very textile handle and a good aging resistance.
• a heel lining in which the multi-component continuous filaments are particularly preferred a cross section with orange-like multi-segment structure have, the segments alternately one of the two incompatible polymers.
• the heel lining is preferably one in which the from the Multi-component continuous filaments formed nonwoven for pre-consolidation is precalanded.
• the material therefore has a very good quality Thickness uniformity.
• a heel lining is also particularly preferred, in which at least one the incompatible polymers that form as a multi-component continuous filament an additive, such as color pigments, permanent antistatic agents and / or the additives influencing hydrophilic or hydrophobic properties in Contains amounts up to 15 wt .-%.
• the heel lining can thereby its lightfastness, the tendency to static charge, the Sweat transport or the moisture retention effect can be positively influenced.
• the addition of the color pigments to the dope enables Production of deep and abrasion-resistant colors.
• a heel lining in which the Multicomponent continuous filament is not crimped because of the textile handle resulting from the good cleavage in super micro continuous filaments is guaranteed.
• the heel lining shows off comparable degrees of impregnation compared to the known synthetic Heel lining materials have superior strength properties.
• the heel lining is advantageously one in which one of the sides has a Hot melt adhesive application is provided.
• a material is especially for suitable for further processing on automatic machines.
• the method according to the invention for producing the heel lining consists in the fact that multi-component continuous filaments are spun from the melt, aerodynamically stretched and immediately laid down to form a fleece, pre-consolidation by pre-calendering or needling and the Non-woven fabric solidified by high pressure fluid jets and at the same time in Super micro continuous filaments with a titer ⁇ 0.2 dtex split as well is then impregnated with a polymer.
• the products so obtained are very even in terms of their strength, because one There is largely isotropic thread distribution in the product. The products show no tendency to delamination and show high module values as well as input and Tear strength.
• Another advantageous embodiment of the method is that the Solidification and splitting of the multi-component continuous filaments takes place that the pre-consolidated nonwoven fabric alternately several times from both High pressure water jets are applied to the sides. That kind of Solidification and splitting of the multi-component continuous filaments leads to very dense nonwovens with smooth surfaces.
• the solidification and splitting of the multicomponent continuous filament is preferred on an aggregate with rotating sieve drums carried out. This form of the aggregates allows the construction to be very compact Investments.
• the impregnated material becomes one more Subsequent treatment by grinding or buffing.
• the structure contained microfilaments creates a particularly fine and noble, nubuck-like surface that is very similar to that of natural leather.
• a non-woven fabric with a basis weight of approx. 160 g / m 2 is produced from a multi-component continuous filament consisting of 65% by weight of poly (ethylene terephthalate) and 35% by weight of poly (hexamethylene adipamide).
• the starting filaments have a titer of approx. 1.8 dtex and consist of 16 segments, with polyester and polyamide segments alternating like orange slits around a central axis.
• the melt-spun, multicomponent filaments are stretched aerodynamically and placed randomly on a belt.
• the nonwoven fabric pile thus obtained is subjected to a pre-calendering at temperatures of approximately 95 ° C. and a pressure of approximately 100 bar.
• a nonwoven fabric is made from polyester and polypropylene staple fibers by intensive needling and impregnated with NBR.
• a heel lining with a basis weight of 320 g / m 2 and a thickness of 0.85 mm is obtained by splitting.
• the abrasion resistance was determined in such a way that a test specimen with 90 mm ⁇ is clamped in a rotary clamping head and loaded with a scouring pressure of 2.8 N / cm 2 .
• the angle of rotation of the clamping head is 50 degrees.
• the test sample is tested against a scouring element that has diamonds on its surface.
