Problems solved by technology

However, kapok fiber has poor spinnability and is difficult to spin purely. Generally, it is blended with cotton, viscose or other cellulose fibers.
[0007] CN201010560000.9 discloses a manufacturing process of kapok fiber blended yarn. The raw materials include various fibers including kapok fiber. The manufacturing process includes blowing, carding, drawing, roving, and spun yarn to prepare a multi-component blended yarn. yarn, the process is more complicated, and it is easy to have the problem of low spinning tensile strength, which restricts its application; and CN201310189047.2 and CN201310189256.7 respectively disclose a blended yarn of cotton fiber, bamboo fiber and kapok fiber and a The blended yarn of cotton fiber, kapok fiber and acetate fiber is only a simple compound of several fibers, which cannot give full play to the advantages of various fibers

Abstract

The invention relates to a kapok composite fiber and a preparation method thereof and belongs to the technical field of textile material production. The kapok composite fiber comprises the following components in part by weight: 5-95 parts of polyester fiber or three-dimensional hollow or hot-melt fiber and 5-95 parts of kapok fiber. The preparation method of the kapok composite fiber comprises the following steps: screening, mixing, mixing into a roll, carding into a net, heat treatment, cooling and the like. The kapok composite fiber has the advantages of high tensile strength, good wear and pressure resistance, good bulkiness, softness and uniformity, and the like; the preparation method is simple and convenient in process, low in production cost, and suitable for industrial production.

Description

technical field [0001] The invention relates to a kapok composite fiber and a preparation method thereof, in particular to a fiber material prepared by compounding kapok fiber and polyester fiber or hollow three-dimensional or hot-melt fiber, belonging to the technical field of textile fiber material processing. Background technique [0002] Since the 20th century, chemical fibers have been produced with the development of polymer materials. The advent of chemical fibers has changed the history that humans have only used natural fibers as the only textile fiber raw material for thousands of years, and has opened up broad prospects for obtaining new textile fibers with better performance. In the past two decades, my country's chemical fiber industry has achieved rapid development. According to the data from the official website, my country's chemical fiber output was 104 tons in 1985 and 24.57 million tons in 2007. Since the development of natural fibers is limited by natura...
