Abstract

The invention provides a preparation method of polypropylene short fibers without peculiar smells, belonging to a field of the preparation method of the polypropylene fiber. The method comprises: adding polypropylene slices into a fusion screw A and a fusion screw B as a surface layer and a core layer, adding the surface layer and the core layer into a metering pump of a spinning machine with a mass percent of 40-60 : 40-60, cladding a tasteless oil agent on surfaces of the fibers after the fibers are molded, obtaining fiber bundles through passing an oiling stick of an oil agent groove, a three-step drawing machine, a setting machine, a crimper, a smell removing groove and a second setting machine, and cutting the fiber bundles by using a cutter to obtain the polypropylene short fibers without the peculiar smells, wherein a fusion index of the polypropylene slices added into the fusion screw A is 32 g / 10 min, a fusion index of the polypropylene slices added into the fusion screw B is 28 g / 10 min, and a temperature of the smell removing groove is 135-145 DEG C. The obtain polypropylene short fibers is free of the peculiar smells.

Description

technical field [0001] The invention belongs to the field of polypropylene fiber preparation methods, and in particular relates to a preparation method of polypropylene staple fibers without peculiar smell. Background technique [0002] At present, most of the materials used for automobile decoration and home decoration are non-woven fabrics made of ordinary polypropylene staple fibers. Spinning finishes are generally used. The main components of these spinning oils are: alkylphenol polyoxyethylene ethers, pentaerythritol fatty acid esters, sorbitol fatty acid esters, alkyl phosphates, alkyl alcohol amides, etc. (Chemical Industry Press, Liu Cheng, Surface Active Agent Application Handbook, Second Edition P467-475,). However, after these spinning oils are attached to fibers and made into non-woven fabrics, they will slowly release the smell of oils, which is harmful to human health. Contents of the invention [0003] The purpose of the present invention is to provide a ...
