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 agriction 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 yarns, in particular to a processing method of kapok yarns with high and high hollow ratios. Background technique [0002] Kapok fiber is the fruit fiber of several plants in the Malvaceae Kapok family. It is a single-cell fiber that is attached to the inner wall of the kapok capsule shell and developed and grown from the inner wall cells. Kapok fiber is generally about 8-32mm in length and 20-45μm in diameter. It is the thinnest, lightest, highest hollow and warmest fiber material among natural fibers. The hollow rate is more than 86%, which is 2-3 times that of ordinary cotton fibers. At the same time, it is smooth, antibacterial, anti-moth, anti-mildew, soft, not easy to tangle, impermeable, non-heat-conducting, ecological, warm, moisture-absorbing and moisture-conducting. And other excellent characteristics, it has a broad development prospect in the textile field. However, during the spinning ...
