Embodiment 1

[0034] Preparation process of nano-modified slices:

[0035] First, on the continuous polyester equipment, use terephthalic acid (PTA) and ethylene glycol (EG) monomers to continuously and stably meter and feed them into the slurry tank according to the molar ratio of PTA and EG at a ratio of 1:1.25 In beating, add nano-silica, nano-zirconia, and matting agent titanium dioxide in the beating kettle, wherein the molar ratio of nano-silica to terephthalic acid is 5.8%, and the addition of nano-zirconia is the same as that of terephthalic acid. The mol ratio of phthalic acid is 1.5%, and the mol ratio of the addition of matting agent titanium dioxide and phthalic acid is 1.5%;

[0036] Then, the above-mentioned slurry is continuously and stably transported to the esterification-I and esterification-II reactors, and the stabilizer is continuously added to the esterification-II reactors at the same time to control the esterification rate to 98.0%, and the viscosity of the melt is...

Abstract

The invention relates to a method for preparing nano silicon dioxide modified polyester fibers, which comprises the steps of preparing a nano silicon dioxide modified polyester slices and spinning by a blending FDY (Fully Drawn Yarn) technology. The method disclosed by the invention can be completed on conventional spinning equipment. Tows have good evenness. Glossy distribution is uniform. A textile fabric is smooth and flat. The nano silicon dioxide modified polyester fibers have the characteristic of soft gloss, can be widely applied to the clothing field, the decoration field and the industry field.

Description

Technical field [0001] The present invention involves a preparation method for synthetic fibers. Specifically, the invention involves a preparation method for a nano -silicon -to -polyester fiber. Background technique [0002] As one of the three main fibers in synthetic fibers, polyester fibers are widely used in clothing fabrics and other non -clothing areas because of its excellent physical and chemical characteristics.Since its inception, polyester products have also been weaving various types of textiles with good hanging, high intensity, and stiffness as the main textile raw materials.With the economic globalization and the internationalization of the market, people's requirements for clothing are getting higher and higher. Not only must they have comfort, but also functionality. The fabrics develop in light, soft, and functional.It is necessary to continuously improve performance to meet the weaving requirements. [0003] In the past ten years, my country's polyester indus...
