Abstract

The present invention relates to a kind of preparation method of wear-resisting and soft polyester bulky filament, and the method comprises the following steps: a. Preparation of talcum powder masterbatch: dry modified superfine talcum powder, carrier, compatibilizer, Dispersants, antioxidants, and transesterification inhibitors are added to a high-speed mixer for mixing, melted and blended by a twin-screw extruder, and granulated; b. Spinning: polyethylene terephthalate or polyethylene terephthalate One of the propylene glycol formate is mixed with polybutylene terephthalate chips, dried, and then mixed with the dried talcum powder masterbatch, and added to the feed screw of the BCF spinning unit at the same time, and the polyester is spun in one step Type bulky filament. Compared with pure polyester fibers, the two kinds of bulked filaments obtained by this method have abrasion resistance increased by more than 30%, and the PBT / PET bulked filaments have high resilience and soft hand feeling similar to PBT-BCF. The fiber properties and the thermal stability of the physical form are significantly improved; the obtained PTT / PBT bulked filament has similar fiber properties to PTT-BCF, and the cost of raw materials is reduced.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber spinning processing, and in particular relates to a preparation method of mixed polyester bulky filaments containing ultrafine inorganic powder. Background technique [0002] Carpet has long been an essential product for high-level architectural decoration, such as widely used as ground decoration materials for residences, hotels, gymnasiums, exhibition halls, vehicles, ships, airplanes, etc. It is a traditional arts and crafts with a long history in the world. One of the categories. [0003] Chemical fiber carpets have the characteristics of light weight, wear resistance, bright colors, comfortable feet, high elasticity, simple laying, and low price. With the continuous innovation of chemical fiber spinning technology and spinning raw materials, the output of chemical fiber carpets in the world has accounted for more than 100% of carpets. If the service life of the carpet is significantly...
