Definitions

• the invention relates to an inner lining for the shoe industry and a method for producing the same.
• Abrasion-resistant materials are used in the shoe industry for lining the inner part of a shoe, the so-called inner lining.
• these materials are intended to support the transport of moisture through perspiration from the foot to the outside to ensure a dry foot, and on the other hand, they should distribute the forces that arise during the rolling motion over the shoe leather over large areas in order to prevent wrinkles and the associated faster wear avoid.
• the object of the invention is to provide an inner lining for the shoe industry which has a basis weight of 80 to 170 g / m 2 Tear and tear strength in the longitudinal as well as in the transverse direction is> 7 N.
• the invention has also set itself the task of specifying a method which is particularly suitable for producing such an inner lining.
• the object is achieved by an inner lining which has a basis weight of 80 to 170 g / m 2 and tear strength both in the longitudinal and transverse directions> 7 N, the inner lining being melt-spun, aerodynamically stretched and immediately deposited into a nonwoven multicomponent Continuous filaments with a titer of 1.5 to 5 dtex and the multicomponent continuous filaments after pre-consolidation are at least 80% split and solidified to form micro continuous filaments with a titer of 0.1 to 0.8 dtex.
• These linings have high tensile strengths and abrasion resistance with low basis weights.
• no hemming is required due to the endless filaments and there is no unraveling and thickening in the area of the seams and thus possible pressure points are avoided.
• the inner lining is preferably one in which the nonwoven fabric consists of melt-spun, aerodynamically stretched and immediately deposited multi-component filaments with a titer of 2 to 3 dtex, and the multicomponent continuous filaments optionally after pre-consolidation are at least 80% micro-continuous filaments are split and solidified with a titer of 0.1 to 0.5 dtex.
• the inner lining has an isotropic filament distribution in the fleece. It is therefore not necessary to take the machine direction into account when cutting the inner lining.
• the inner lining is preferably one in which the multicomponent continuous filament is a bicomponent continuous filament made of two incompatible polymers, in particular a polyester (PES) and a polyamide (PA). The multi-component continuous filament therefore has good splittability and a very favorable ratio of strength to basis weight.
• the inner lining is preferably one in which the multicomponent continuous filaments have a cross section with an orange-like or also called “pie” structure, the segments alternately each containing one of the two incompatible polymers.
• the multicomponent continuous filament is a "side-by-side" (s / s) segment arrangement of the incompatible polymers in the multicomponent continuous filament is also possible, which is preferably used to produce crimped filaments.
• Such segment arrangements of the incompatible polymers in the multicomponent continuous filament have proven to be very easy to split.
• the inner lining has a very favorable ratio of basis weight to insulation, so that soft and warm inner lining can be produced in particular by subsequent treatment steps such as roughing.
• the inner lining is preferably one in which the from the
• Multicomponent continuous filaments formed pre-consolidation preconsolidation.
• the material therefore has very good thickness uniformity.
• the inner lining is particularly preferred in which at least one of the incompatible polymers forming a multicomponent continuous filament contains an additive, such as color pigments, permanent antistatic agents and / or additives which influence the hydrophilic or hydrophobic properties in amounts of up to 15% by weight.
• an additive such as color pigments, permanent antistatic agents and / or additives which influence the hydrophilic or hydrophobic properties in amounts of up to 15% by weight.
• the inner lining can be positively influenced with regard to its light fastness, the tendency towards static charging, the transport of sweat or the moisture accumulation effect.
• the addition of the color pigments to the spinning mass enables the production of deep and abrasion-resistant colors.
• an inner lining in which the multi-component continuous filament is uncrimped is particularly preferred, since this guarantees the textile handle as a result of the good splittability in micro continuous filaments.
• the inner lining is advantageously one in which one of the sides is provided with a hot-melt adhesive application.
• a hot-melt adhesive application is particularly suitable for further processing on automatic machines.
• the process according to the invention for producing the inner lining consists in spinning multicomponent continuous filaments from the melt, stretching them aerodynamically and depositing them immediately to form a nonwoven fabric, if necessary pre-consolidation by pre-calendering or needling and the nonwoven fabric being consolidated by high-pressure fluid jets and simultaneously in micro- Continuous filaments with a titer of 0.1 to 0.8 dtex, preferably with a titer of 0.1 to 0.5 dtex, is split.
• the products obtained in this way are very uniform in terms of their strength, because there is a largely isotropic thread distribution in the product.
• the products show no tendency to delamination and have high module values as well as tear and tear strength.
• Farther have the inner lining according to the invention very good
• Moisture transport properties that promote the comfort of the shoe provided with it with regard to the water vapor transport and the drying of wet shoes.
• a further advantageous embodiment of the method is that the solidification and splitting of the multicomponent continuous filaments takes place in that the optionally pre-consolidated nonwoven fabric is subjected to high pressure water jets at least once from each side.
• This type of solidification and splitting of the multi-component continuous filaments leads to very dense nonwovens with smooth surfaces.
• the last high-pressure water jet treatment is preferably carried out on a screen support with mesh sizes of 5 to 50 mesh. This additionally strengthens the lining material, makes it more abrasion-resistant and gives it a textile look.
• the impregnated material is preferably subjected to post-treatments such as dyeing, tumbling, grinding and / or sanforizing. These measures can improve the surface quality and the grip of the material obtained.
• a filament pile with a basis weight of 110 g / m 2 is produced from a PES-PA bicomponent continuous filament and alternately subjected to water jet needling with pressures of up to 280 bar from both sides.
• the water jet needling is carried out in a total of four treatment passages, the fourth passage being carried out on a 20 mesh sieve pad.
• This creates a structured and / or perforated Surface is created and the inner lining is given a textile look and a soft feel. Due to the water jet needling, the initial filaments are split to a titer of ⁇ 0.2 dtex.
• the inner lining produced in this way is subjected to jet dyeing and can be used without regard to the machine direction.
• the inner lining obtained has the strength parameters given in the table below and is well suited for the stated purpose.
