Abstract
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.
Claims34
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-m2.
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.
The fabric, according to claim 25, 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%.
A method for producing a fabric comprising:
- a) drawing filaments through an attenuation device;
- b) depositing the filaments onto a collection surface to form a web;
- c) bonding the web together to form a fabric;
- and
- d) coating the fabric with a coating that comprises silicone;
- wherein the fabric has a denier per filament of about 3.5 or less.
