Problems solved by technology

The method of the invention is used to post-treat the mixed yarn of kapok fiber and cotton fiber, which can solve the small sub-yarns caused by the high twist of kapok blended yarn, the hairiness of the yarn is improved, the smoothness is improved, and the customer response is good. increase, the weaving end breaks of downstream enterprises are greatly reduced; however, in this invention, most of the cavity wall of the kapok fiber has been flattened during the spinning process of the cotton kapok yarn, and the shaping process makes the kapok fiber in the process of dyeing, finishing, scouring and finishing In the process, it is not easy to restore the circular cavity wall. In addition, the tension, tightness and yarn shape of the winding are adjusted by the metal pressure piece of the yarn guide device of the winding machine. When the yarn passes through the metal tension piece, it is pressed under the action Increased the crushing and wear of kapok fiber, which cannot solve the problem of kapok fiber loss

Embodiment 1

[0025] The blended yarn count that present embodiment adopts is 40 pounds;

[0026] S1. At 40-50°C, use RFS-222 fatty acid organic amine compound and add water to fully reconcile and evenly prepare a treatment solution containing 10% of the compound;

[0027] S2. Humidification treatment of impregnated blended yarn: Put the upper part of the bobbin downwards into the prepared treatment solution. The upper part is placed upwards, so that the treatment liquid flows into the lower part of the non-impregnated bobbin from top to bottom; the bobbin is formed by winding cotton and kapok blended yarn on the bobbin;

[0028] S3. Cover with a closed plastic film, cover and stew the yarn to fuse with the infiltration solution, and leave it for 6-8 hours; after 6 hours, start to test the humidity and moisture regain;

[0029] S4. Use a portable yarn moisture meter of model YG201B to test the humidity and moisture regain, the two are respectively: 55-75% and 15-22%, and then weave on the ...

Abstract

The invention discloses a cotton and kapok blended yarn and a humidifying and softening pretreatment method thereof. The cotton and kapok blended yarn is formed by blending cotton fibers and kapok fibers, wherein kapok fibers account for 5-20%, and cotton fibers account for 5-20%. 80‑95%; blended kapok fibers and cotton fibers have good compatibility, which can reduce excessive wear and tear during spinning; the pretreatment method uses the dipping method to pretreat the blended yarn before weaving, so The blended yarn has good hydrophilicity and antistatic performance, so that excessive kapok fiber hairiness is not easy to be worn and broken during the weaving process, thereby saving energy consumption.

Description

technical field [0001] The invention belongs to the technical field of blended yarns, in particular to a blended yarn and a pretreatment method thereof. Background technique [0002] Kapok fiber is the fruit fiber of kapok tree. The fiber is attached to the inner wall of the kapok capsule shell and grows from the inner wall cells. It belongs to single-cell fiber like cotton fiber. Kapok fiber is a kind of natural cellulose fiber, which has the characteristics of environmental protection, high hollowness, good warmth retention, natural antibacterial, moisture absorption and moisture conduction. With the improvement of spinning technology, kapok fiber has been widely used. [0003] The surface of kapok fiber is smooth, without turning, thin wall, large hollow, and flat strip after being flattened; the average length of kapok fiber is 16mm, which is much shorter than cotton fiber; kapok fiber is thin and brittle, and it is difficult to test the strength of single fiber.
