Abstract

The invention discloses an uvioresistant type biomass polyester fiber and a preparation method of the uvioresistant type biomass polyester fiber. The uvioresistant type biomass polyester fiber is characterized in that the uvioresistant type biomass polyester fiber is prepared from the following raw materials in percentage by weight: 1-5% of uvioresistant type master batches and the balance of biomass polyester chips. The preparation method comprises the step of performing melt spinning on the uvioresistant type master batches and the biomass polyester chips to obtain the uvioresistant type biomass polyester fiber. The bio-based polyester raw material is prepared from bio-based ethylene glycol and bio-based 1, 3-propylene glycol through biological fermentation and purification, the traditional petroleum base ethylene glycol is replaced, environment protection and sustainable development are facilitated, and nano titanium nitride has small grain diameter and large specific surface area and has the efficacy on ultra violent resistance.

Description

technical field [0001] The invention relates to an anti-ultraviolet type biomass polyester fiber and a preparation method thereof, belonging to the technical field of functional fibers. Background technique [0002] With the development of the global economy, the demand for oil is increasing day by day, while oil resources are decreasing day by day, the contradiction between oil supply and demand is becoming more and more serious, and the war for oil is intensifying. The whole world is working hard to research and explore the inexhaustible biological resources on the earth. Using renewable biomass resources to develop bio-based chemical industry and replace petrochemical products is the only way to solve the resource and energy crisis and an important way for sustainable development. Therefore, the development of raw materials that can reduce or replace petroleum is a very important research direction. [0003] Polyester polyester fiber itself has excellent performance and...
