Coated fabrics with increased abrasion resistance
View Patent ↗A silicone coating is applied to fabrics to increase the abrasion resistance while enhancing the natural absorbency and breathability. These fabrics can be used for a variety of applications such as components for shoes, inkjet receptive media, automotive air bags, facing for insulation, tapes and other uses.
1. A coated fabric with a denier per filament of 3.5 or less that:
has a reduced air permeability that is no lower than 25% of the air permeability compared to the uncoated fabric of the uncoated fabric;
passes the SATRA TM 31: Method A: 2003 Martindale Abrasion test for 51,200 dry revolutions and 12,800 wet revolutions; and
has a water vapor transmission above 250 g/day-m 2 .
2. The fabric, according to claim 1 , with a stiffness level below 2 Lb f .
3. The fabric, according to claim 1 , wherein the coating comprises silicone.
4. The fabric, according to claim 1 , where the uncoated fabric is a nonwoven fabric wherein the filaments are made from polyesters, polyamides, polyimides, polypropylene, polyethylene, polystyrene, TEFLON®, fiberglass, polybutylene terephthalate, polytrimethylene, polylactic acid, polycarbonates, polyester terephthalate polybutylene terephthalate, acrylic, or polyvinyl alcohol polymers or a combination of these polymers.
5. The fabric, according to claim 4 , where the nonwoven fabric is a spunbonded fabric.
6. The fabric, according to claim 5 , where the spunbonded fabric is a nylon nonwoven fabric.
7. The fabric, according to claim 6 , where the nylon fabric is made from nylon 6; nylon 6,6; nylon 11; nylon 12; or a combination or copolymer of these nylons.
8. The fabric, according to claim 5 , where the spunbonded fabric is a polyester nonwoven fabric.
9. The fabric, according to claim 1 , where the uncoated fabric is made of multicomponent fibers made from at least two polymers from polyesters, polyamides, polyimides, polypropylene, polyethylene, polystyrene, TEFLON®, fiberglass, polybutylene terephthalate, polytrimethylene, polylactic acid, polycarbonates, polyester terephthalate polybutylene terephthalate, acrylic, or polyvinyl alcohol polymers or a combination of these polymers.
10. The fabric, according to claim 1 , where the denier per filament is two or less.
11. The fabric, according to claim 1 , where the uncoated fabric has been printed.
12. The fabric, according to claim 1 , where a metallic coating has been applied to the uncoated fabric prior to applying the silicon coating.
13. The fabric, according to claim 6 , where the nylon spunbonded fabric is thermally bonded.
14. The fabric, according to claim 6 , wherein the nylon spunbonded fabric is autogenously bonded and has a smooth surface without a bond pattern.
15. The fabric, according to claim 1 , further comprising at least one of the group selected from antimicrobial, fungicides, and fire retardants.
16. A fabric comprising a plurality of filaments, wherein the fabric has a denier per filament of about 3.5 or less, and wherein the fabric is coated with a coating that comprises silicone.
17. The fabric, according to claim 16 , wherein the fabric passes the SATRA TM 31: Method A: 2003 Martindale Abrasion test for 51,200 dry revolutions and 12,800 wet revolutions.
18. The fabric, according to claim 16 , wherein the fabric has a water vapor transmission of at least about 250 g/day-m 2 .
19. The fabric, according to claim 16 , wherein the stiffness level of the fabric is about 2 Lb f or less.
20. The fabric, according to claim 16 , wherein the fabric is further coated with a metallic coating.
21. The fabric, according to claim 16 , wherein the fabric is a spunbonded nonwoven nylon fabric.
22. The fabric, according to claim 16 , wherein the fabric is a nonwoven fabric, and wherein the filaments comprise polyesters, polyamides, polyimides, polypropylene, polyethylene, polystyrene, TEFLON®, fiberglass, polytrimethylene, polylactic acid, polycarbonates, polyester terephthalate, polybutylene terephthalate, acrylic, polyvinyl alcohol polymers, or blends or copolymers thereof.
23. The fabric, according to claim 22 , wherein the filaments comprise polyethylene, and wherein the polyethylene has a melt index between about 5 grams/10 minutes and about 200 grams/10 minutes, and wherein the polyethylene has a density between about 0.85 grams/cc and about 1.1 grams/cc, and wherein the concentration of the polyethylene is between about 0.05% and about 20%.
