Abstract

The invention discloses a dacron color silk with a photocatalytic degradation function and a preparing method of the dacron color silk. The method comprises the following preparing steps that firstly, photocatalysts are modified and are made into PET (polyethylene terephthalate) master batches containing nanometer TiO2; then, the PET master batches are subjected to mixed fusion spinning with PET slices and color master batches; finally, the obtained nanometer TiO2-PET color silk is subjected to base reducing processing to obtain the dacron color silk with the photocatalytic degradation function. The dacron color silk has the advantages that the process condition is simple; the popularization is convenient; the functional purpose of textiles produces in the subsequent production procedures of the dacron color silk is widened.

Description

technical field [0001] The invention relates to the field of preparation of polyester dyed yarn, in particular to a polyester dyed yarn with photocatalytic degradation function and a preparation method thereof. Background technique [0002] Polyester dyed yarn is usually made of polyester (PET) chips and masterbatches through high temperature melt spinning. Its main features are: (1) It does not require dyeing, shortens the production process of textile products, solves the problem of environmental pollution during the dyeing process, and avoids damage to fiber properties during dyeing. (2) The textile products produced by using colored polyester yarns have good fastness properties such as soaping, sunlight and friction. (3) Polyester dyed yarns of different colors enrich the options of textile processing and are widely favored by end textile products in the market. [0003] Photocatalytic degradation usually refers to the gradual oxidation of organic matter into low-mole...
