The hollow cotton yarn has the characteristics of lightness, bulkiness, softness, water absorption, quick drying and warmth; belongs to functional yarn, but the final product has single appearance style and lacks three-dimensional layering, and the requirements of consumers are difficult to meet.
Therefore, how to overcome the above defects of the existing cotton hollow yarn becomes one of the problems to be solved in the field.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a method for manufacturing hollow bunchy yarn, which comprises the specific steps of feeding a cotton fiber semi-finished sliver and a soluble fiber pre-drawing sliver through a bundling device simultaneously, drawing, roving, adding a bunchy yarn device through a spinning process, drafting, twisting, winding and spinning to prepare hollow bunchy towel yarn cop, winding and weaving to prepare grey cloth, and carrying out post-treatment to prepare a final product; the obtained hollow slub towel yarn has the characteristics of softness, fluffiness, water absorption, quick drying and warmness of the hollow yarn, and has the appearance of uneven thickness distribution, and thick and thin nodular slub yarns, short fiber slub yarns, filament slub yarns and the like can be produced by adjusting the slub yarn device process, so that the final product has the advantages of outstanding pattern, unique style and strong stereoscopic impression, and is a comprehensive yarn which has functionality and outstanding appearance style.
The main inventive concept of the present invention is as follows:
cotton is a natural fiber with good water absorption properties and very good skin-friendly properties to the human body, but it is prone to wrinkling, lacks bulk and is heavy in weight, while synthetic fibers are just on the best in these respects, which is one reason why synthetic fibers can be popular, but none of them has skin-friendly properties comparable to cotton. The inventor of the present invention developed hollow slub yarn to overcome the disadvantages of heavy weight and insufficient bulkiness while maintaining the advantages of cotton fiber, as the characteristic of adding synthetic fiber to cotton fiber is a subject of cotton fiber development.
The traditional hollow yarn utilizes a spun yarn hollow yarn device, PVA filament yarn or PVA yarn core yarn and cotton fiber are used as sheaths, and after the yarn is formed, soluble PVA fiber is removed through a fiber removing process to obtain a hollow yarn product. The invention is mainly characterized in that a special bundling device is added in the last process in the spinning process, the central channel of the bundling device is set as a water-soluble fiber professional channel, a cotton fiber channel is arranged around the central channel, a composite yarn spinning process is applied to take water-soluble fibers as yarn cores and cotton as the outer layers of yarns, the initial yarns have a double-layer structure, after spinning, post-processing and dissolving treatment is carried out, the water-soluble fiber yarn cores are dissolved, holes are left in the middle of the yarns, 100% cotton yarns with annular hollow structures are formed, and meanwhile, a slub yarn device is added in the spinning process, so that a cotton fiber yarn with a brand new structure is produced, and the application field of cotton textiles is widened.

Comparative example:
compared with the finished product produced by normal arrangement without a collector, the finished product produced by additionally arranging the special collector on the last pass has the following characteristics:
1. the appearance is unique, the appearance style of the terry after being woven into the towel is greatly different from the appearance style of the traditional conventional terry yarn, the style is unique, the three-dimensional layering is strong, and the appearance is novel and unique;
2. due to the effect of the special collector, the water-soluble fibers are uniformly concentrated in the center of the cotton sliver, so that compared with a product produced without the collector in normal arrangement, the product with the feeding device can reduce the probability that the water-soluble fibers are dispersed on the surface of the yarn, and the final product has a hollow effect. After the water-soluble fiber is removed, the structure of the yarn is changed, a water guide channel is formed along the twisting track of the plied yarn, the water guide channel can not only quickly absorb moisture, but also quickly evaporate and escape the moisture after washing, so that the yarn and the towel manufactured by the invention have the functions of easy wetting and quick drying;
according to the figure 3, the cross section of the finally obtained hollow slub towel yarn is enlarged, the PVA is eccentric, but the cotton fiber is wrapped outside, and the fluffy and water absorption effects are not influenced by the structure after experiments; the yarn obtained by the prior art without the bundling device in the last process has the cross section which is observed at the edge position of the PVA through amplification, and the test shows that the product is soft, fluffy, anti-wrinkle and water absorption effects are far behind those of the PVA obtained by the invention, namely the PVA is an eccentric product:
through tests, the towel made of the yarn absorbs water faster than a conventional towel, a national standard sedimentation method is adopted for testing, and the water absorption of a bunchy yarn towel product produced by a conventional drawing process before washing is generally more than 20 s; the water absorption of the hollow bunchy yarn towel product manufactured in the drawing process after the bundling device is additionally arranged is within 5s, and the towel is dried by a dryer, so that the drying time of the towel can be saved by about 5min compared with the same conventional towel;
3. the hand feeling is good, and the yarn main body can form a hollow structure after the water-soluble fiber is dissolved, so that the hand feeling of the product is more fluffy.
Second, compared with the pure cotton slub yarn, the hollow slub yarn manufactured by the method of adding the soluble fiber has the advantage that the breaking strength of the hollow slub yarn is obviously improved under the condition that the yarn number, the twist coefficient and the slub shape are the same.
