Method for producing kapok scribbled by ring spinning

Abstract

The present invention discloses a method for producing kapok scribbled by ring spinning, in which the mixed raw materials of kapok fibers and other fibers are subjected to the processes of opening and scutching, carding, drawing, roving, spinning, etc., and a device of guiding cotton sliver is provided after a carding procedure, wherein the said spinning adopts a double-short-apron drafting mode, the said carding is performed twice, and the said drawing is performed twice. The blended yarns produced according to the inventive method have the superior technical indexes in terms of the single yarn breaking tenacity, single yarn elongation at break, etc. which are better than the industrial standard of cotton berber yarn. And the shell fabric produced from the product of the invention has the superior technical indexes in terms of the fabric heat retention, fabric moisture vapour transmission, fabric touching cold-warm feeling, fabric bulking intensity, fabric compressive elastic recovery ratio and fabric soft draping property, etc. which are better than those of the similar products such as the pure cotton and polyester cotton, etc.

Description

TECHNICAL FIELD[0001]The present invention relates to a process for producing scribbled with kapok as raw material, especially to a method for producing kapok scribbled by ring spinning.BACKGROUND ART[0002]The kapok fiber is the fruit fiber of a woody plant. But the kapok fiber is difficult to be processed into yarn since it has a hollow volume percentage of over 80%, thin cell wall, a short length, a high rigidity, and an extra small specific gravity. However, the kapok fiber is super-fine and soft so that the face fabric made of the kapok fiber has the super softness like cashmeres. In addition, the kapok fiber has the same chromaticity as that of pure cotton, and good moisture absorbent, moisture conductive, antibacterial, anti-acarid, hollow and warm-keeping properties. Therefore, the kapok fiber is a textile material having good prospect of being exploited.[0003]The spinning processes have been studying since 80's of the last century in our country and much researches have been...

AI Technical Summary

Benefits of technology

[0006]The said spinning process adopts a double-short-apron drafting mode which can effectively reduces the roller gauge, and a method of the nose bar and support is adopted to effectively improve slivering of the resultant yarns.

[0013]Twice drawing: is to reduce the heterogeneity of the cotton slivers in weight, mix the fibers adequately and increase the straightness and parallelism of fibers.

[0014]Roving: by drafting and twisting, to further improve the dissociation degree and straightness of fibers, and reduce the areal weight of cotton slivers to be prepared for spinning, wherein the Roller-cradle drafting process with two drafting fields and a front adjustment field is employed so as to effectively reduce the roller gauge, improve silvering of roves and reduce flaws.

[0016]The spinning adopts a double-short-apron drafting mode which can reduce the roller gauge effectively. And a lower-pin-upper-bracket mode is adopted to effectively improve the slivering of resultant yarn.

[0018]The warm-keeping underwear made by knitting or tatting with the product prepared according to the method of the invention has good warm-keeping effect which is 1.56 times higher than that of the common warm-keeping underwear. And its heat conduction resistance is 20% higher than that of the pure cotton underwear; and heat convection resistance is 2˜3 times as that of the pure cotton underwear. Moreover, this underwear is soft and warm for touching, and has the properties of moisture absorbent, moisture conductive, comfortable for wearing, antibacterial and anti-acarid etc.

Problems solved by technology

But the kapok fiber is difficult to be processed into yarn since it has a hollow volume percentage of over 80%, thin cell wall, a short length, a high rigidity, and an extra small specific gravity.

The spinning processes have been studying since 80's of the last century in our country and much researches have been done by the researchers in the textile industrial, however, a progress has been made only in the open-end spinning process, and no breakthrough have been made in other mass production spinning processes, especially in the ring spinning process.
