Abstract
Woven fabrics from blends of high and low modulus fibers provide comfort plus high durability to hard surface abrasion.
Claims21
A highly durable woven fabric made from yarns of discrete staple fibers having good textile aesthetics comprising 8-70% high modulus organic staple fibers having a modulus of greater than 200 g/dtex and a linear density of less than 10 decitex per fiber and 30-92% low modulus organic staple fibers having a modulus of less than 100 g/dtex and a linear density of less than 10 decitex per fiber and the fabric having a Specific Wyzenbeek Abrasion Resistance on at least one face of the fabric at least 25% greater than the Specific Wyzenbeek Abrasion Resistance on the same face of a greige fabric of the same basis weight and construction made from 100% of the high modulus staple fibers, the warp yarns of said fabric containing at least 15% of the high modulus organic staple fibers and at least 30% of the low modulus organic staple fibers.
A highly durable woven fabric made from yarns of discrete staple fibers having good textile aesthetics comprising 8-70% high modulus organic staple fibers having a modulus of greater than 200 g/dtex and a linera density of less than 10 decitex per fiber and 30-92% low modulus organic staple fibers having a modulus of less than 100 g/dtex and a linear density of less than 10 decitex per fiber and the fabric having a Specific Wyzenbeek Abrasion Resistance on at least one face of the fabric of greater than 5 cycles g/m.sup.2, the warp yarns of said fabric containing at least 15% of the high modulus organic staple fibers and at least 30% of the low modulus organic staple fibers.
A highly durable woven fabric made from yarns of discrete staple fibers and having good textile aesthetics comprising 8-70% high modulus organic staple fibers having a modulus greater than 200 g/dtex and 30-92% of low modulus organic staple fibers having a modulus of less than 100 g/dtex, the warp yarns of said fabric containing at least 15% of the high modulus organic fibers and at least 30% of the low modulus fibers, said fabric having a fabric tightness greater than 1.0 and a fiber tightness greater than 1.0.
