Problems solved by technology

Since polypropylene does not contain chemical groups that can be combined with dyes in its macromolecular structure, dyeing is more difficult and production is more difficult. There are large errors in the appearance and color of different batches of products, and overshooting in dyeing will cause A large amount of waste water, waste gas, waste residue and other three wastes pollute the environment and are not environmentally friendly

Abstract

The invention belongs to the technical field of fiber manufacturing, and in particular relates to a method for producing pre-spinning dyed coarse denier polypropylene ATY fiber used outdoors. The method includes the following steps: (1) preparing pre-spinning dyed coarse denier PP (polypropylene) FDY fiber, to be more specific, using PP slices and colored masterbatch as raw materials for preparingthe pre-spinning dyed coarse denier PP (polypropylene) FDY fiber by precrystallization, drying, mixing, extrusion, filtration, spinning, side blow cooling, oiling and winding, wherein the addition amount of the colored masterbatch is 2- 10% of the weight of the PP slice; and (2) producing of the pre-spinning dyed coarse denier polypropylene ATY fiber, to be more specific, using the pre-spinning dyed coarse denier PP (polypropylene) FDY fiber obtained in the step (1) as a raw material for air deformation and heat finalizing to obtain the pre-spinning dyed coarse denier polypropylene ATY fiber,the color difference is small, and the sun fastness is high, and the production process has no three wastes pollution, and is green and environmentally-friendly.

Description

technical field [0001] The invention belongs to the technical field of fiber manufacturing, and in particular relates to a production method of pre-spinning colored coarse denier polypropylene ATY fiber for outdoor use. Background technique [0002] Polypropylene is a fiber made from propylene as a raw material through polymerization and melt spinning. Polypropylene officially started industrial production in 1957 and is a rising star among synthetic fibers. Because polypropylene has the advantages of simple production process, low price, high strength and light relative density, the development of polypropylene is very fast. At present, polypropylene fiber is the fourth largest variety of synthetic fibers and the lightest fiber among common chemical fibers. The varieties of polypropylene include filaments (including undeformed filaments, space-changing filaments and bulky deformed filaments), short fibers, bristles, split fibers, hollow fibers, shaped fibers, various comp...
