Abstract

The invention relates to the field of synthesized fibers and discloses a preparation method of modified polyester cellosilk. The preparation method comprises the following steps: coating and curing polyester cellosilk with a resin coating; and then carrying out a thermal treatment process. The resin coating is prepared by stirring and mixing epoxy resin with a curing agent in a weight ratio of 100: (50-100). In the thermal treatment, the temperature is controlled at 100-180 DEG C and the time is controlled at 10-30 min. The modified polyester cellosilk has the characteristics of being low in elongation at break, hard to deform and the like. The modified polyester cellosilk is spun to prepare polyester fiber cloth for coastal reclamation, so that the coastal reclamation effect is good and the cost is low.

Description

technical field [0001] The invention belongs to the field of synthetic fibers, and in particular relates to a preparation method of modified polyester fiber filaments. Background technique [0002] Polyester fiber is commonly known as "polyester". It is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol, referred to as PET fiber. It was invented in 1941 and is currently the largest variety of synthetic fiber. It has excellent wrinkle resistance, elasticity and dimensional stability, good electrical insulation performance, sunlight resistance, friction resistance, mildew and moth resistance, good chemical resistance, weak acid and weak alkali resistance. But it does not absorb moisture, is not resistant to high temperature, and has a large elongation at break. [0003] Polyester filaments are used to make polyester fiber cloth. Polyester fiber cloth can be used to hold stones and use them for land recla...
