Abstract
A method for producing a dyed cotton fabric having an improved characteristic salt-and-pepper look and the product thereof. The process includes forming a plurality of individual cotton yarns having a twist multiple value of at least 4.6 and, preferably, subjecting the twisted cotton yarn to exposure to a caustic solution under tension. The yarn then is dyed under tension by exposure to a dye liquor. The treated yarn is used to produce a woven fabric, which after being abraded, has a lighter portion dispersed throughout a darker portion. In the preferred embodiment the twist multiple value of the cotton yarn threads varies within the range of between 4.6 and 10.5.
Claims25
A method of producing a fabric, comprising the steps of:
- (a) forming a plurality of individual cotton yarns having a twist multiplier value of at least 4.6 and varying within the range of between 4.6 and 10.5;
- (b) subjecting said plurality of individual cotton yarns to exposure to a caustic solution under tension;
- (c) dyeing said plurality of individual cotton yarns by exposure to a dye liquor under tension to achieve dyeing of the other periphery of the individual yarns with very little dyeing of their cores;
- (d) utilizing said plurality of individual cotton yarns to produce a fabric;
- and
- (e) abrading at least one surface of said fabric, whereby first and second portions of the surface of said fabric are different shades of color, providing lighter portions dispersed throughout a darker portion, said lighter portions having fractional area value of greater than about 33%.
A method of producing a fabric comprising the steps of:
- (a) forming a plurality of individual cotton yarns having a twist multiplier value greater than 4.6 and varying within the range of between 4.6 and 10.5;
- (b) dyeing said plurality of individual cotton yarns by exposure to a dye liquor under tension to achieve dyeing of the outer periphery of the individual yarns with very little dyeing of their cores;
- (c) utilizing said plurality of individual cotton yarns to produce a fabric;
- and
- (d) abrading at least one surface of said fabric, whereby first and second portions of the surface of said fabric are different shades of color, providing lighter portions dispersed throughout a darker portion, said lighter portions having a fractional area value of greater than 33%.
A method of producing a specialty yarn, comprising the steps of:
- (a) forming a plurality of individual cotton yarns having a twist multiple value of at least 4.6;
- (b) subjecting said plurality of individual cotton yarns to exposure to a caustic solution under tension sufficient to maintain shrinkage at less than 5%;
- and
- (c) dyeing said plurality of individual cotton yarns by exposure to a dye liquor under tension.
A method of producing a fabric, comprising the steps of:
- (a) forming a plurality of individual cotton yarns having a twist multiplier value of at least 4.6.
- (b) tensioning the yarns and subjecting said plurality of individual cotton yarns to exposure to a caustic solution having a concentration value of between 15.degree. and 75.degree. Tw while the yarns are under tension;
- (c) dyeing said plurality of individual cotton yarns by exposure to a dye liquor under tension to achieve dyeing of the outer periphery of the individual yarns with very little dyeing of their cores;
- (d) utilizing said plurality of individual cotton yarn to produce a fabric;
- and
- (e) abrading at least one surface of said fabric, whereby first and second portions of the surface of said fabric are different shades of color, providing lighter portions dispersed throughout a darker portion, said lighter portions having a fractional area value of greater than about 33%.
