Optional anti-velvet cloth the right way to bile 
 Overall, as the functional requirements of anti-velvet fabric must first performance, fabric formation, different colors, evenly distributed, without breaking through, weft phenomenon; second requirement feel fine, full soft; also requires a good vapor permeability through wetland functions; and clean cloth, effective width are 1.47 meters. 
 Specifically: 
 1, anti-cashmere performance: the value of its breathable fabric down proof fabric by the meter to detect the low permeability R ≤ 6; anti-drilling Cashmere performance testing, take anti-velvet gall sewing cloth into a square 41cm * 82cm, respectively, filled with down 90% cashmere wool 80g bag made by YG819-type anti-drilling Cashmere tester does not test drilling at 10,000 rpm velvet, and then 20 hours of continuous still no drilling machine washable cashmere phenomenon; with no broken trail, weft phenomenon that is able to guarantee strong performance against velvet. Product density must be chosen ≥ 260T. 
 2, handle: delicate, soft and plump, but must be guaranteed on the basis of cashmere against the pursuit of soft, otherwise the fastness of fabric will be destroyed, and the organization will certainly affect the loose fabric down proof function. The requirements of the hand must be moderate. 
 3, good barrier permeability features: Oil by ASTM E96 BW water vapor permeability testing equipment and testing methods can be tested, the index> 50000g / m * 24h, otherwise they will be too much breath, affecting the appearance and wearing a down jacket comfort. 
 4, oil clean, and effective width are 1.47 meters. Easy to cut, well-used. 
 5, fully meet the above criteria, then choose the number of full-meter, the price for anti-velvet cloth bile wise choice.
