Abstract

The invention provides a preparation method of an anti-ultraviolet polyester fabric suitable for outdoor operations, which is carried out according to the following steps: the raw vermiculite is ground to a powder state, and the raw vermiculite powder of the micron scale is screened out; The raw vermiculite powder is heated and dried; the raw vermiculite powder is added to the polyester chip, heated and stirred; the heating is continued and the heat is kept to obtain a molten state modified polyester; the modified polyester chip is spun at a high speed on a spinning machine to form a primary fiber; adopt the parallel drawing machine to shape the nascent fiber to obtain polyester fiber; weave the polyester fiber into polyester fabric by conventional method; dye the polyester fabric to obtain the finished polyester fabric. The invention utilizes the special performance and structure of vermiculite and adopts a special fiber preparation method to obtain polyester fabrics with good ultraviolet resistance, and adds ternary copolymerization silicone softener for post-finishing, which can improve the color fixing effect and is suitable for dark colors. The color fixing effect of polyester fabrics is particularly remarkable.

Description

technical field [0001] The invention relates to the field of functional clothing fabrics, in particular to a method for preparing an anti-ultraviolet polyester fabric suitable for outdoor operations. 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 of...
