Problems solved by technology

The characteristics of its yarn formation are light, bulky and soft. However, during the sizing process, the water-soluble vinylon will shrink when heated, and the strength of the yarn will be greatly reduced, which will affect weaving.
Especially in the yarn-dyed industry, the yarn must be dyed before weaving. During the dye

Embodiment Construction

[0013] The present invention will be further described below in conjunction with embodiment:

[0014] The technological process of described embodiment is:

[0015] Colored cotton slivers are dyed, dehydrated, dried, packed, plucked, mixed, opened, rolled, and carded to form colored cotton slivers; vinylon fibers are plucked, mixed, sent, rolled, and carded Form vinylon sliver; draw colored cotton raw sliver and vinylon sliver at a quantity ratio of 80:20 to form a mature sliver, mix and draw the sliver, and then produce excellent spinning hollow yarn through roving and spun yarn.

[0016] Treatment of colored sliver: after raw cotton is dyed into black, yellow, blue, green, etc., it is mixed with white cotton according to a certain mixing ratio according to product requirements, and the proportion of colored cotton is 5%-50% to form colored sliver after loose fiber dyeing , dehydration, drying, packing, plucking, mixing, opening, rolling, and carding to form colored cotton s...

Abstract

The invention discloses a method for producing color-spun and hollow yarns, which is novel hollow yarn and color-spun yarn integrated spinning technology. The colored-cotton fibers are subjected to loose stock dyeing, and are coiled by a clear cotton machine, and slivered by a slivering machine; the silvered colored-cotton fibers and the vinylon fibers silvered by carding are folded on a drawing frame, rough yarns are spun by a coarse spinner, and the color-spun and hollow yarns are spun by a spinning frame. In the method, the problem that water-soluble vinylon is heated and shrunk and the strong force of yarns is greatly reduced so as to influence weaving in the process of weaving and starching the hollow yarns is effectively solved.

Description

technical field [0001] The invention relates to a yarn production method, in particular to a production method of colored spinning hollow yarn. Background technique [0002] Hollow yarn is composited with water-soluble fiber (generally vinylon fiber) made by composite spinning technology and solvent wet gel spinning method. Its structure is cotton in the outer layer and water-soluble fiber in the inner layer to form a double layer. structure. After adjusting the spinning process, the water-soluble fiber is effectively and evenly coated on the inner side of the cotton fiber, and then after post-processing (removal), the inner fiber is dissolved to form a ring-shaped hollow yarn. The characteristics of its yarn formation are light, bulky and soft. However, during the sizing process, the water-soluble vinylon will shrink when heated, and the strength of the yarn will be greatly reduced, which will affect weaving. Especially in the yarn-dyed industry, the yarn must be dyed bef...
