Problems solved by technology

However, the spinning and drawing speeds used in this method are as high as 5000-6500 m / min. The equipment technology is complex and expensive, and it is currently controlled by a few foreign companies such as the American HONEYWELL company, the German KOSA company, and the Korean Hyosung company. The conventional domestic industrial spinning equipment with mature technology such as: two-step industrial filament spinning machine model SKV402, drafting machine model VC432A and one-step industrial filament spinning drafting machine model KV452, with ordinary Polyester chips cannot produce high-strength, high-modulus, low-shrinkage polyester industrial yarns, which restricts the production and application of domestic polyester industrial yarns

Abstract

The invention relates to nano SiO2 polyester composite materials and industrial yarn preparation process, wherein the composite material contains 0.2-10 weight portions calculated on solid basis of single particle dispersed spherical nano SiO2 with particle diameter of 9-12 nm in each 100 weight portion of polytetramethylene terephthalate, the inherent viscosity range of the nano SiO2 polyester composite materials is between 0.80-1.10.

Description

technical field [0001] The invention relates to a nano-SiO 2 Industrial yarn made from polyester composite material and its preparation method. Background technique [0002] Polyester material is made of terephthalic acid and ethylene glycol, in the presence of catalysts and stabilizers, through esterification and polycondensation of polyethylene terephthalate, referred to as PET. This ordinary polyester material is a thermoplastic polymer material with excellent performance and low price. It is widely used in the production of packaging materials such as synthetic fibers, films and beverage bottles, and engineering plastics. Although the application of polyester materials has made great progress, this common polyester material itself still has certain defects in terms of crystallinity, heat resistance, gas barrier properties, dimensional stability, etc. Ester industrial yarn, especially to prepare polyester industrial yarn with high strength, high modulus, low shrinkage, ...
