Abstract

The invention discloses a rare-earth hybrid in-situ polymerized polyolefin / polypropylene blended fine denier and dyeable fiber special resin and a preparation method thereof. The method comprises the following steps: adding Na2S2O3 into an aqueous solution containing a dispersant, then adding a mixture of surface-modified nano-rare earth particles, an initiator and a modified olefin monomer, reacting, aging and then mixing with polypropylene, melt blending, extruding, Rare earth hybrid in-situ polymerization polyolefin / polypropylene blended fine-denier dyeable fiber special fiber resin is obtained, the mass percentage is: polypropylene 92-98%, hybrid modified polyolefin 2-8%. The obtained dyeable polypropylene blended resin has good fluidity and can be melt-spun to obtain fibers with a monofilament fineness of 0.9-2dtex. The prepared fibers have relatively good anti-ultraviolet and anti-aging functions, and can effectively improve Improve the dyeability of polypropylene fibers.

Description

technical field [0001] The invention relates to a dyeable polypropylene blended resin and its preparation. Background technique [0002] Fibers made of ordinary polypropylene are not widely used in the field of clothing because of poor dyeability and poor hygroscopicity as clothing fiber materials. In recent years, due to the development of fine denier and ultra-fine denier (single filament size less than 1 dtex) polypropylene fibers produced by special processing methods, polypropylene fabrics are endowed with significant moisture perspiration and perspiration properties and are widely used in close-fitting clothing, such as high-end Sweatshirts, underwear and spring and autumn clothing fabrics. [0003] Scholars at home and abroad have studied the dyeability of polypropylene fibers. There are usually two types of methods, one is to modify the fiber surface, but the cost of this method is higher; Adding other components to the polypropylene fiber and then blending and spi...
