Abstract

The invention relates to the synthetic fiber field and particularly discloses a preparation method of a modified polyester fiber filament. The preparation method comprises the steps of coating a polyester fiber filament with a modified resin coating, and carrying out curing and thermal treatment, wherein the modified resin coating is prepared by the steps of stirring and mixing epoxy resin with acoating agent in a weight ratio of 100 to (50-100), and adding 2%-10% of quartz sand; and the temperature of the thermal treatment is controlled at 100-180 DEG C, and the time of the thermal treatmentis controlled at 10-30 minutes. The obtained modified polyester fiber filament has the characteristics of low breaking elongation rate, difficulty in deformation and the like; and modified polyesterfiber cloth spun by virtue of the modified polyester fiber filament is specially applied to sea reclamation, the sea 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...
