Embodiment 1

[0033] Preparation process of nano-calcium carbonate modified slices:

[0034] First, on the continuous polyester equipment, use terephthalic acid (PTA) and ethylene glycol (EG) monomers to continuously and stably meter them into the slurry tank according to the molar ratio of PTA to EG of 1:1.25 Beating, adding nano-calcium carbonate and titanium dioxide in the beating kettle, wherein the mol ratio of the addition of nano-calcium carbonate to terephthalic acid is 5.2%, and the mol ratio of the addition of matting agent titanium dioxide to phthalic acid is 1.7%;

[0035] Then the above-mentioned slurry is continuously and stably transported to the esterification-I and esterification-II reaction kettles, and the stabilizer is continuously added to the esterification-II reaction kettles at the same time to control the esterification rate to about 98.0%, and the viscosity of the melt is controlled to 0.66 ; The esterified product is pumped to the polycondensation section, and the...

Abstract

The invention relates to a preparation method of a nanometer calcium carbonate modified polyester fiber. The preparation method comprises the preparation of a nanometer calcium carbonate modified polyester chip and a process of spinning with a blended FDY (fully drawn yarn) technology. The method of the invention which can be completed with routine spinning equipment allows uniform yarn evenness, uniform color distribution, and smoothness of the fabric to be realized and has the characteristic of soft luster, so the method can be widely applied to the clothing field, the decoration field and the industrial field.

Description

technical field [0001] The present invention relates to a kind of preparation method of synthetic fiber, specifically, the present invention relates to a kind of preparation method of nano calcium carbonate modified polyester fiber. Background technique [0002] As one of the three main fibers in synthetic fibers, polyester is widely used in clothing fabrics and other non-clothing fields because of its excellent physical and chemical properties. Since its inception, polyester products have also been used by downstream users as the main textile raw material to weave various textiles due to their good drapability, high strength and crispness. With the globalization of the economy and the internationalization of the market, people's requirements for clothing are getting higher and higher. Not only must they be comfortable, but they must also be functional. There is a constant need to improve performance to meet weaving requirements. [0003] In the past ten years, my country'...
