Abstract

The invention discloses a high-strength low-shrinkage polypropylene filament and a preparation method thereof, and specifically relates to the technical field of the polypropylene filament. A main ingredient used comprises the following ingredient in parts by weight: 60-80 parts of polypropylene. While preparing the polypropylene filament, silica gel particles and color master batch are poured into a raw material, a main material of the silica gel particles is silica gel, after being solved with the polypropylene, hygroscopicity of the silica gel is relatively higher, so the prepared polypropylene filament has certain hygroscopicity, thereby, the polypropylene filament is suitable for a clothing industry, usage range of the polypropylene filament is increased, and the silica gel has bettertoughness, after being solved with the polypropylene, toughness of the polypropylene filament is increased greatly, the polypropylene filament is enabled to be used in more worse environment, whereinthe added color master batch can increase colors needed, types of the color master batch are selected and inside of the color master batch is provided with colorant, so, pigment adsorptivity in the polypropylene is increased, and a situation of color fading is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of polypropylene filaments, in particular to a high-strength and low-shrinkage polypropylene filament and a preparation method thereof. Background technique [0002] The scientific name of polypropylene filament is polypropylene fiber. It melts and shrinks when it is near the flame. It is flammable and burns slowly away from the fire and emits black smoke. The upper end of the flame is yellow and the lower end is blue. The twist is brittle. It is a fiber made from propylene as raw material through polymerization and melt spinning. [0003] The prior art has the following deficiencies: the existing polypropylene filaments mainly use polypropylene as the main material, and the polypropylene produced by polypropylene has poor hygroscopicity, which limits the scope of use of polypropylene. The dyeing process is more difficult. Contents of the invention [0004] For this reason, the...
