IMPROVING PILLING RESISTANCE IN FABRICS USING CELLULOSE ACETATE STAPLE FIBERS

A method of making a pilling-resistant fabric is provided. In one instance, the method comprises (a) blending a cellulose acetate (CA) staple fiber with a non-CA staple fiber to form a blended yarn comprising 20 to 80 wt % of the CA staple fiber and (b) forming a pilling-resistant fabric comprising...

Summary:A method of making a pilling-resistant fabric is provided. In one instance, the method comprises (a) blending a cellulose acetate (CA) staple fiber with a non-CA staple fiber to form a blended yarn comprising 20 to 80 wt % of the CA staple fiber and (b) forming a pilling-resistant fabric comprising the blended yarn. In another instance, the method comprises (a) providing a first yarn comprising at least 20 wt % of a CA staple fiber and (b) forming a pilling-resistant fabric comprising the first yarn and a second yarn comprising a non-CA staple fiber. The CA staple fiber has (i) a round or closed-C cross-sectional shape, (ii) a cut length of 20 to 80 mm, (iii) a crimp frequency of 4 to 24 crimps per inch (CPI), and (iv) a denier per filament (DPF) of 0.5 to 4.0. The pilling-resistant fabric has a higher pilling resistance rating than a fabric made without the CA staple fiber.
