Abstract
This invention relates to a latent looped yarn having loops produced by an eddy current treatment and once potentialized therein before a weaving operation and revealed in a fabric, after the yarns are woven therein at least as warp yarns, by heat treatment, to give the fabric a spunlike handling and high yarn density. This invention also provides a manufacturing method for producing the latent looped yarn and high density spunlike fabrics utilizing the latent looped yarn.
Claims17
A high density fabric comprising:
- (a) warp yarns comprising a mixed composite multifilament yarn consisting of synthetic multifilament yarns having opened loops and closed loops on the surface thereof, wherein the cover factor of said warp yarns is more than 1100;
- and
- (b) weft yarns.
A mixed fabric having high density comprising:
- (a) warp yarns or weft yarns comprising mixed composite multifilament yarns consisting of at least a synthetic multifilament yarn having a shrinking function and having fine opened loops and closed loops on the surface thereof;
- and
- (b) weft yarns or warp yarns comprising spun yarns;
- wherein the total cover factor of said warp yarns and said weft yarns is from 2000 to 3500.
A method of manufacturing a fabric having a spunlike feeling and resembling a fabric made of super high length cotton fibers, in which said fabric is woven with mixed composite multifilament yarns made of synthetic multifilaments having a total denier of less than 90d and said composite yarn consists of a filament a having a shrinkage ratio in hot water of more than 12% and a denier of a component filament thereof is more than 1.5d and total denier thereof is less than 60d and a filament b having a shrinkage ratio in hot water of less than 10% and a denier of a component filament thereof is less than 1.0d and total denier thereof is less than 60d, and said composite yarn is further characterized by having more than 30 0ends/m of the loop A, more than 50 ends/m of the loop B, and less than 10 ends/m of the loop C, each of said loop A, loop B, and loop C being defined hereunder, thereafter a shrinking treatment is applied to said fabric to cause a differential shrinkage between said filament a and filament b which results in projecting said opened loops and closed loops of said filament B on the surface of said fabric, wherein each of said loop A, loop B and loop C is defined in such a manner that when each loop is measured under a condition of a yarn speed of 50 m/min and a yarn running tension of 0.1 g/d, by using a photo-electric type fluff measuring device by which the number of loops of a yarn running therethrough is counted, a loop projecting more than 0.15 mm from a yarn surface is defined as a loop A, a loop projecting more than 0.35 mm from a yarn surface is defined as a loop b and a loop projecting more than 0.6 mm from a yarn surface is defined as a loop C.
