Abstract
The invention relates to a heel lining for use in the shoe industry comprising a polymer impregnated non-woven having a surface area weight of 180 to 350 g/m2 and a tear strength of > 15 N in a longitudinal and a perpendicular direction. The non-woven consists of melt spun, aerodynamically stretched multi-component endless filaments which are arranged directly to form a non-woven. Said non-woven has a titer of < 2 dtex. The multi-component endless filaments are split and hardened when said filaments have attained a pre-defined strength of 90 % of the supermicro-endless filaments, i.e. a titer of < 0.2 dtex.
Description
Heel Lining for Use in the Shoe Industry Description The invention relates to a heel lining for the shoe industry and to a process for its manufacture.
In the shoe industry, especially abrasion resistant materials are used for the lining of the posterior part of a shoe, the so-called heel cap. These materials are meant to absorb the forces which are exerted by the foot onto the shoe in longitudinal direction, especially during the rolling off movement, while they must on the other hand withstand the friction forces which are caused by the foot moving at least partly up and down in the shoe during walking. In order to prevent an undesired slipping out of the shoe during the rolling off movement, a raw or suede leather material is traditionally used as heel lining which by friction between the foot or the sock of the wearer prevents the sliding out of the shoe.
Synthetic materials are also used, apart from the heel liners made of natural materials. These synthetic materials are needled nonwovens which are dry manufactured by crimping from polyester, polyamide, polypropylene fibers or mixtures of those fibers.
Fibrous naps with a surface weight of up to $00 g/m-' are used and mechanically consolidated by intensive needle punching. This process step alone is very time intensive and therefore relatively cost intensive. A
shrinking of the needled nonwoven by hot air or steam normally follows, which leads to a densification of the material as well as a further consolidation with a view to adjustment of the density desired for the respective purpose. In order to achieve the required strength parameters as well as initial and progressive rupture resistance of the needled nonwoven, the latter is impregnated with a heat coagulating latex binder dispersion such as styrene-butadiene-caoutchouc (styrene rubber - SBR), or nitrite-butadiene caoutchouc (nitril-butadiene rubber -NBR), and subsequently dried. The latex portion is about 30 to 60 % by weight of the impregnated nonwoven. The material so prepared is split into two to four thinner layers. This splitting process was adopted from the leather industry for nonwoven materials in order to increase the productivity in the nonwoven manufacture. The split products can also be buffed for evening out of the surface and for improvement of the optical finish.
Subsequently, a hot melt glue is applied to one of the two sides in order to simplify the further processing.
Disadvantageous in the previously used synthetic heel lining are most of all the very different strength values in longitudinal and transverse direction, the loss of strength occurring because of the splitting of the fiber bundles oriented perpendicularly by the needle punching and the unevenness of the individual layers with respect to the needle penetration and exit sides.
It is an object of the invention to provide a heel lining for the shoe industry which at surface weights of 180 to 350 g/mz has initial and progressive rupture resistance in longitudinal as well as transverse direction of >15N.
It is further an object of the invention to provide a process especially suited for the manufacture of such a heel lining.
In accordance with the invention, this object is achieved with a heel lining which is made of a nonwoven impregnated with a polymer, having a surface weight of 180 to 350 g/m2 and progressive rupture resistance both in longitudinal and transverse direction of >15N, whereby the nonwoven is made of melt spun aerodynamically stretched mufti-component endless filaments immediately laid down into a nonwoven and having a titer of <2 dTex, and the mufti-component endless filaments after a pre-consolidation are split at least to 90% into super-micro endless filaments with a titer of 0.2 dTex and consolidated. These heel linings have higher tension strength and abrasion resistance at a lower surface weight.
The heel lining is preferably one wherein the mufti-component endless filament is a bi-component endless filament of two incompatible polymers, especially a polyester and a polyamide. The mufti-component endless filament thereby has a good splitablility and a favorable ratio of strength to surface weight.
The heel lining is preferably one wherein the polyester portion in the mufti-component fiber is higher than the polyamide portion, especially in the range of the weight ratio of polyester to

The heel lining is preferably one wherein the mufti-component endless filament is a bi-component endless filament of two incompatible polymers, especially a polyester and a polyamide. The mufti-component endless filament thereby has a good splitablility and a favorable ratio of strength to surface weight.
The heel lining is preferably one wherein the polyester portion in the mufti-component fiber is higher than the polyamide portion, especially in the range of the weight ratio of polyester to
2 polyamide of 1.1 : 1 to 3 : 1. The heel linings thereby have a very textile hand a good abrasion resistance.
Especially preferred is a heel lining wherein the multi-component endless filaments have a cross-section with orange type multi-segment structure, whereby the segments alternatinaly respectively include one of the two incompatible polymers.
The heel lining is preferably one wherein the nonwoven formed from the mulit-component endless filaments is pre-calendared for a pre-consolidation. The material thereby has a good thickness consistency.
Especially preferred is furthermore a heel lining, wherein at least one of the two incompatible polymers forming the mufti-component endless filaments includes an additive such as color pigments, permanently active anti-statics and/or additives influencing the hydrophilic or hydrophobic properties, in amounts of up to 15% by weight. The heel lining can thereby be positively influenced with respect to its light fastness, the tendency to statically charge, the sweat transport or the humidity accumulation action. Furthermore, the addition of color pigments into the spinning matter allows for the manufacture of deeper and abrasion resistant colors.
In another especially preferred heel lining the mufti-component endless filament is uncrimped, since the textile hand resulting from the good splittability into super-micro endless filaments is thereby guaranteed.
In accordance with the invention, a heel lining is especially preferred wherein the nonwoven material is impregnated with 20 to 50% by weight of a polymer, relative to the starting weight of the nonwoven material. Relative to the known synthetic heel lining materials, the heel lining has superior strength characteristics at comparable impregnation rates.
Preferably, one of the sides of the heel lining is provided with a hot melt adhesive. Such a material is especially suited for the further processing on automated machinery.

3 In the process in accordance with the invention for the manufacture of the heel lining the multi-COIllp017ent endless filaments are spun from the melt, aerodynamically stretched and immediately deposited into a nonwoven, a pre-consolidation by pre-calendaring or needle punching is carried out, and the nonwoven material is consolidated by high pressure fluid jets and simultaneously split into super-micro endless filaments with a titer of <0.2 dTex and subsequently impregnated with a polymer. The products obtained are very even with respect to their strength capacity, since a widely isotropic thread distribution exists in the product. The products do not show any tendency to delamination and have high module values as well as initial and progressive tear resistance.
In a further embodiment of the process the consolidation and splitting of the multi-component endless filaments is carried out in that the pre-consolidated nonwoven material is repeatedly subjected alternatingly from both sides to high pressure fluid jets. This type of consolidation and splitting of the multi-component endless filaments leads to very dense nonwoven materials with smooth surfaces.
The consolidation and splitting of the mufti-component endless filaments is preferably carried out on a machine with rotating sieve dorms. This type of machines allows the construction of very compact installations.
In an especially preferred manner, the impregnation of the nonwoven predominantly split into super-micro endless filaments and consolidated is carried out with an aqueous polyurethane or NBR-latex dispersion. Solvent residues are thereby avoided and the impregnation carried out with a polymer in an especially environmentally friendly manner.
In a preferred manner, the impregnated material is still subjected to an after treatment by grinding or buffing. The surface consistency and hand of the material obtained can still be improved by these measures. An especially fine and noble nubuk type surface is generated by the micro filaments contained in the structure, which is very similar to that of natural leather.

4 Example A nonwoven nap with a surface weight of about 160 yJ!m' is produced from a multi-component endless filament consisting of 65% by weight of polv(ethylene terephthalate) and 35% by weight of poly(hexamethylene adipamide). The starting filaments have a titer of about 1.8 dTex and consist of 16 segments, whereby polyester and polyamide segments alternate about a central axis like orange wedges. The melt spun mufti-component endless filaments are aerodynamically stretched and randomly deposited onto a belt. The nonwoven nap obtained is guided to a pre-calendaring at temperatures of about 95 °C and a pressure of about 100 bar. After a mechanical consolidation by needle punching a water jet treatment is carried out at about 100 bar water pressure. The splitting of the mutli-component endless filaments into super micro endless filaments with a titer of about 0.1 dTex and a consolidation of the nonwoven material is subsequently carried out with high pressure water jets. The treatment is respectively carried out twice from both sides at water pressures of 250 to 300 bar and on sieve supports with a mesh width of 50 to 100 mesh. The nonwoven is subsequently dried and subjected to an impregnation with a polymer by way of a dry-in-wet treatment with NBR-latex. 125% by weight of NBR are applied relative to the starting weight of the nonwoven material and fixed by drying at 180°C. A
heel lining of a weight of 260 g/m'- and a thickness of 0.75 mm is obtained after the grinding.
Comparative Example A nonwoven material is produced by intensive needle punching from polyester and polypropylene staple fibers and impregnated with NBR. A heel lining with a surface weight of 320 g/mz and a thickness of 0.85mm is obtained by splitting.
A comparison of the strength parameters and the abrasion resistance is summarized in the following Table 1. The abrasion resistance was determined by clamping a sample with 90mm diameter and loaded with a scrubbing pressure of 2.8 N /cm2. The rotation angle of the clamping head is 50 degrees. The test sample is tested against a scrubbing element having diamond shapes on its surface. The measurement sample is wetted with water and cyclically reciprocated, whereby a scrubbing cycle consists of about 300 reciprocations, which is followed by a visual evaluation by way of a grading guide.
