Abstract

Abstract An elastic dampening roll cover knitted in the form of a tubular sleeve comprising knitted courses and wales of inelastic absorbent yarn, with an elastic yarn interlaced with the courses and wales around the circumference of the tubular sleeve, said inelastic absorbent yarn comprising a substantially inelastic air-bulked yarn having a plurality of substantially continuous filaments which are individually convoluted into coils, crunodal loops and whorls at random intervals along their length and the surface of said yarn having a plurality of crunodal loops irregularly spaced therealong, said elastic yarn comprising an elastic core strand and a wrapping strand associated with the elastic core strand in the form of doubled-back loops wound with false twist for a multiplicity of turns around the circumference of the elastic core strand.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 142 words
An elastic dampening roll cover knitted in the form of a tubular sleeve comprising: knitted courses and wales of inelastic absorbent yarn, said inelastic absorbent yarn comprising a substantially inelastic bulked yarn having a plurality of substantially continuous filaments which are individually convoluted into coils, crunodal loops and whorls at random intervals along their length and having a multiplicity of crunodal loops irregularly spaced along the yarn surface; said inelastic absorbent yarn is an air-bulked filament, core and effect yarn comprising nylon and rayon; and, an elastic yarn interlaced with said courses and wales around the circumference of said tubular sleeve, said elastic yarn comprising an elastic core strand and an absorbent wrapping strand associated with said core strand in the form of doubled-back loops wound with false twist for a multiplicity of turns around the circumference of said elastic core strand.
