Embodiment 1

[0016] (1) Using kapok fiber surface coating technology, coating liquid formula: polyurethane 20%, dimethylformamide 72%, fluorine-containing water repellent 3%, stearyl alcohol 5%, the above percentages are all weight percentages; coagulation liquid Formula: water and 20% dimethylformamide; the coating process is: loose fiber→dipping coating→coagulation→washing→drying→finished product, first place the loose fiber in the coating solution and soak for 30 minutes, and then coagulate Soak in the bath for 30 minutes, then wash and dry, and the temperature should be kept at 80°C during drying;

[0017] (2) The friction spinning spinning process for kapok fiber is adopted: open and clear cotton → carding → 1 drawing → friction spinning machine, blending with cotton fiber, the mixing ratio of kapok is 20%, and the friction roller speed is 4000r / min, get kapok yarn.

Embodiment 2

[0019] (1) Using kapok fiber surface coating technology, coating liquid formula: polyurethane 25%, dimethylformamide 70%, fluorine-containing water repellent 3%, stearyl alcohol 2%, the above percentages are weight percentages; coagulation liquid Formula: water and 25% dimethylformamide; the coating process is: loose fiber→dipping coating→coagulation→washing→drying→finished product, first place the loose fiber in the coating solution and soak for 40 minutes, and then coagulate Soak in the bath for 25 minutes, then wash and dry, and the temperature should be kept at 75°C during drying;

[0020] (2) The friction spinning spinning process for kapok fiber is adopted: open and clear cotton → carding → 2 draws → friction spinning machine. It is blended with cotton fiber, the mixing ratio of kapok is 30%, and the rotating speed of the friction roller is 4500 r / min to obtain kapok yarn.

Embodiment 3

[0022] (1) Using kapok fiber surface coating technology, coating liquid formula: polyurethane 28%, dimethylformamide 70%, fluorine-containing water repellent 1%, stearyl alcohol 1%, the above percentages are all weight percentages; coagulation liquid Formula: water and 30% dimethylformamide; the coating process is: loose fiber→dipping coating→coagulation→washing→drying→finished product, first place the loose fiber in the coating solution and soak for 60 minutes, and then coagulate Soak in the bath for 20 minutes, then wash and dry, and the temperature should be kept at 70°C during drying;

Abstract

The invention relates to a processing method of a high hollow ratio kapok yarn. The method is as follows: (1) an elastic film is coated on the surface of the kapok fiber; and (2) friction spinning is performed to the coated kapok fiber, wherein the technology of friction spinning comprises the following steps: opening and picking, performing cotton carding, drawing 1-2 slivers and spinning with a griction spinning machine to obtain the kapok yarn. By adopting the processing method of the invention, the defect that the hollowness of the traditional kapok fiber can not be maintained after spinning process can be overcome, the spinnability of the kapok fiber can be improved, the product development of the kapok yarn can be promoted; and the fabric prepared from the kapok yarn has incomparable and unique warmth retention property and health property and good application prospect.

Description

Technical field [0001] The invention belongs to the field of spinning kapok yarn, and particularly relates to a method for processing kapok yarn with high hollow rate. Background technique [0002] Kapok fiber is the fruit fiber of several plants in the Kapok family of the Malvaceae. It is a single-cell fiber, which is attached to the inner wall of the shell of the kapok capsule and developed and grown by the inner wall cells. Kapok fiber is generally about 8 to 32 mm in length and 20 to 45 μm in diameter. It is the thinnest, lightest, most hollow and warmest fiber material among natural fibers. The void ratio is more than 86%, which is 2-3 times that of ordinary cotton fiber. At the same time, it has smooth, antibacterial, mothproof, mildewproof, gentle, non-entangled, impermeable, non-conductive, ecological, warmth, moisture absorption and moisture conduction. And other excellent characteristics, it has broad development prospects in the textile field. However, due to various...
