Abstract

The invention relates to linen composite fiber and a preparation method thereof, and belongs to the technical field of production of textile fiber materials. The linen composite fiber comprises the following components in parts by weight: 5 to 95 parts of polyester fiber or three-dimensional hollow or hot-melt fiber and 5 to 95 parts of linen fiber. The preparation method comprises sieving, mixing, coiling, carding to form a net, thermal treatment, cooling and the like. The linen composite fiber has the advantages of high tensile strength and wearing and compression resistance, excellent water absorption, softness and uniformity and the like. The preparation method is simple in technology, lower in production cost and suitable for industrial production.

Description

technical field [0001] The invention relates to a flax composite fiber and a preparation method thereof, in particular to a fiber material prepared by compounding flax fiber and polyester fiber or hollow three-dimensional or hot-melt fiber, and belongs 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...
