Abstract

The invention relates to a polyolefin composite fiber. The fiber number is between 1.0 and 7.0dtex; the cross section has a round and sheath core structure; polyolefin containing nanometer pearl powder is taken as a surface layer, polyolefin containing attapulgite is taken as a core layer, and a mass ratio of the surface layer to the core layer is 25:75 to 80:20; and the attapulgite in the core layer accounts for 1 to 10 percent of the mass of the core layer, and the nanometer pearl powder in the surface layer accounts for 3 to 20 percent of the mass of the surface layer. The polyolefin composite fiber is prepared by a surface-core type composite melt spinning process. The fiber has skin affinity, antistatic behavior, health-care function, pearly luster and smooth handfeel and has the effects of improving strength and heat resistance of the fiber and removing peculiar smell. In addition, the core layer does not contain the nanometer pearl powder, so that the total using amount of the nanometer pearl powder is low, the production cost is reduced, and the additional value is improved. The polyolefin composite fiber can be used for clothing, medical and hygienic products, bedding products and the like.

Description

technical field [0001] The invention relates to the technical field of functional fibers, in particular to a polyolefin composite fiber. Background technique [0002] Polyolefin fibers (including polypropylene fibers and polyethylene fibers) have excellent properties such as low density, high strength, corrosion resistance, and good resilience, and the raw material production and spinning process is simple, pollution-free, low raw material and comprehensive energy consumption, and low cost. Inexpensive, widely used in clothing, medical and sanitary nonwovens and industrial fibers. However, polyolefin fibers also have many obvious performance defects, such as strong waxy feeling, poor hygroscopicity and dyeability, and easy to accumulate static charges on the fibers. Therefore, the modification of polyolefin fibers has become a research hotspot, and its methods include copolymerization, blending, compounding and surface modification. [0003] Pearl powder contains a lot of ...
