  • This invention provides a fabric that possesses significantly improved abrasion resistance with minimal weight add on, so that breathability and hand are not significantly impeded
  • the polymeric material on the surface of the fabric is deposited in a manner that does not adversely affect the aesthetic qualities
  • the abrasion is often improved by 50-100% or higher, e g , 1000% or more, with little to no effect on breathability
  • woven or knitted fabrics that are made of yarn, either natural or synthetic, such as wool, cotton, polyamide, polyester, polyolefin, aramid and the like
  • the woven or knitted fabrics could have surfaces that are sanded, embossed, knapped, flocked, fleeced, etc
  • the fabrics used in the invention are water vapor permeable, having a moisture vapor transmission rate of at least 1000 g/m 2 .24 hours
  • the polymeric material applied to the fabric can be a polyurethane, polyamide, polyester, polyolefin, silicone, acrylic or the like
  • the polymer could be water-vapor-permeable, as well This, however, is generally not necessary, provided that the percentage coverage of the fabric surface is not too great to substantially affect the water-vapor-permeability thereof
  • polyurethanes are known to be excellent in resisting abrasion which make them ideal materials for applications requiring a high level of abrasion resistance from the polymer layer
  • they can be formulated to yield a high degree of softness, making them excellent candidates where the handle of the finished composite is of concern
  • the structure of the abrasion resistant layer of this invention will still work to provide a relative level of abrasion resistance
  • Fillers and additives may also be used to enhance other properties or to further increase the abrasion resistance, and may be used in conjunction with any of the aforementioned processes to provide a suitable, or in some instances superior, product
  • polymer selection will also be affected by the type of fabric the abrasion resistant layer is being applied to It is usually best to select a polymer to provide chemical compatibility between the polymer and the fabric,
  • the general process employed to make the products of this invention is to apply a plurality of polymeric fibers to the surface of the fabric
  • Techniques such as heat treating non-woven webs into the fabric surface, as well as melt blowing and fibenzing polymer fibers directly onto the surface, can be used Upon subsequent heat treatment, the polymeric fibers melt, losing their identity
  • the resulting polymeric appearance can be random, interconnected, discrete or the like, depending on the aforementioned heat treatment
  • a benefit of using fine, lightweight non-woven webs is the ability to create structures which minimize the distance between polymer areas, providing for better local abrasion resistance as is needed around cuffs, collars, pocket edges, and generally any folds or creases
  • the web can simply be laid over the fabric and heated to a temperature which melts the polymer but not the fabric Melting of the polymeric filaments destroys the non-woven web structure and causes formation of the discontinuous, randomly disposed polymeric material and adherence to the fabric surface
  • the porous web forming polymer is usually laid down on the substrate in the form of filaments, as shown in Fig 3
  • a subsequent heating step is carried out at a temperature above the softening point of the polymer to cause the filament polymer to flow and spread to form the structures shown in Fig 4, 5 and Fig 6
  • the heating is most conveniently carried out in an oven, e g , hot air or IR
  • the desired structure may form on the fabric without any further application of heat
  • Another process which can be used to create the current invention is by spray fibenzing of low viscosity resins consisting of polymers, prepolymers, or ohgomers (for example, using an apparatus such as the ITW Dynatec's Uniform Fiber Depositor — Hendersonville, TN)
  • This technique is similar to melt blowing, except the viscosities of the resins are generally lower and the resins typically require some post processing to build viscosity
  • spray fibenzing a urethane pre-polymer would require a curing step (for example, heat treatment if it has a blocked isocyanate group) to build molecular weight and hence viscosity and ultimately coating integrity
  • sihcones would require a post heat treatment step, along with a catalyst such as platinum, to initiate polymerization and improve coating integrity, prior to taking up in a roll form
  • Another process that could be employed involves the deposition of meltable discontinuous fibers or powders onto the surface of the fabric followed by subsequent melting of the particulate
  • the percentage coverage of the surface of the fabric by the polymer is in the region 10-90%, more particularly 30-70 It will be appreciated that the spacing between areas of polymer should not be so great as to permit ready access to open areas whereby abrasion of these open areas may occur
  • meltblowing is one preferred method to form a polymeric, porous web on the fabric
  • a fiber forming polymer is extruded from an extruder that can have one orifice or multiple orifices directly into convergent high velocity heated air streams to produce fine filaments
  • the melt blown filaments are deposited on the moving substrate in an entangled, random fashion and are then fused to form a coherent coalesced porous web of filaments
  • the degree of coalescing and the degree of adherence to the substrate can be furthered by subsequent heating above the softening point It is also seen in Figs 4, 5, and 6 that an intermediate temperature of heating displays an intermediate degree of fiber coalescing and adherence to the substrate Heating times may be as little as a few seconds, e g , 3 to 5 seconds, or can be longer, e g , 30 to 60 seconds or more
  • the web forming polymer is preferably chosen to be compatible with the fabric surface so that the web filaments readily adhere to the substrate surface as they are laid down or as later heated
  • thermoplastic elastome ⁇ c polyurethane polymer is one of a number of polymers that are found satisfactory for the formation of filaments in accordance with he present invention It will be appreciated, however, that other polymeric materials can also be used provided their abrasion resistance is satisfactory for their purpose and they are able to be bonded to the fabric with which they are to be used
  • the fabric on the side opposite that on which the polymeric material is adhered, can be laminated to or coated with other layers to form a multi-layered composite
  • the other side of the fabric may be attached or adhered to a water-resistant, water vapor permeable film or membrane, such as a monolithic breathable polyurethane or polyester polyether film or a porous, especially microporous, polyethylene or polypropylene or polyurethane
  • a preferred membrane or film is composed of an expanded polytetrafluoroethylene (ePTFE) membrane as disclosed in US Patent No 3,953,566, which has a porous microstructure characterized by nodes interconnected by fibrils
  • the membrane is resistant to passage of liquid water therethrough but is water- vapor-permeable

  • Samples were evaluated for abrasion resistance, as determined by visual inspection, using a modified universal wear test method The method is based on ASTM standard D3886-92 and consists essentially of abrading a sample with a selected abradant and determining the number of cycles until a hole visually appears through the test sample

Abstract

La présente invention concerne des tissus dotés d'une bonne résistance à l'abrasion. Le tissu utilisé dans cette invention est un tissu tissé ou en mailles réalise à partir d'un filé monobrin ou multibrin. Une très légère application de polymère, par exemple entre 5 et 40 g/m2, est appliquée à la surface du tissu de façon à en améliorer la résistance à l'abrasion, généralement par application d'un voile léger non tissé d'un matériau polymère de fusion-soufflage filé-lié, ou par fusion-soufflage ou pulvérisation d'un matériau polymère directement sur le tissu de façon à former un voile. Après application sur sa surface du polymère, le tissu peut être éventuellement chauffé de façon que les filaments du voile fondent et perdent leur nature fibreuse.
