Abstract

The invention provides a preparation method of environment-friendly light-color anti-ultraviolet polyester fabric. The method comprises the following steps: grinding raw vermiculite into powder, and screening out micro raw vermiculite powder; heating and drying the raw vermiculite powder; adding the raw vermiculite powder to a polyester chip, and performing heating and stirring; performing heatingcontinuously and keeping the temperature to obtain molten modified polyester; spinning the modified polyester chip on a spinning machine at high speed to prepare nascent fiber; setting the nascent fiber by a parallel drafting machine to obtain polyester fiber; spinning the polyester fiber into polyester fabric with a conventional method; dyeing the polyester fabric to obtain a finished polyesterfabric product. By use of the special performance and structure of vermiculite and the special fiber preparation method, the polyester fabric with good ultraviolet resistance is obtained, and naturalplant fibers are adopted for dyeing in the following dyeing process, and the preparation method is more environmentally friendly than traditional anti-ultraviolet polyester fabric preparation methods.

Description

technical field [0001] The invention relates to the field of functional clothing fabrics, in particular to a preparation method of an environment-friendly light-color anti-ultraviolet polyester fabric. Background technique [0002] As the most widely used chemical fiber, polyester fiber has good fiber-forming and mechanical properties, high strength, good light resistance, heat resistance and acid and alkali resistance, good processability and spinnability, and can be purely spun or blended and interweave. Polyester fabrics are washable, wear-resistant, non-ironing and wrinkle-resistant, and are widely used in clothing, home textiles, decoration and product applications. However, polyester fiber also has disadvantages such as poor hygroscopicity, non-sweat-absorbing fabric, stuffy feeling when worn, poor anti-static ability, and easy to be stained with dust, which greatly restricts the application and development of polyester fiber. In order to improve the wearing comfort ...
