Pure polyester spinning finisher

Abstract

The invention discloses a pure polyester spinning finisher, which comprises the following components: fatty acid polyglycol ester, sodium dodecyl sulfate, trimethylolpropane tricaprylate, kaolin, sepiolite, ethylhexyl palmitate, 2-mercaptobenzimidazole, polyethylene glycol octadecylene, triethanolamine oleate, dioctyl sebacate, sodium acetate, zinc oxide, N, N-dimethylaniline, diallyl phthalate, and potassium persulfate. By means of the specific components and the weight parts of the components, the pure polyester spinning finisher provided by the invention has improved coating performance to polyester fiber, and the coat rate is as high as 99.5%, the rate of waste silk caused by filament bifurcation and end breakage is reduced to 4.3%, bifurcation, end breakage and other damage situations occurring to the produced yarns is significantly reduced, the quality of the prepared pure polyester is improved, and the cost is reduced.

Description

technical field

[0001] The disclosure generally relates to the technical field of synthetic fiber materials, in particular to pure polyester fibers, and in particular to pure polyester spinning oils. Background technique

[0002] Pure polyester, also known as polyester fiber, is one of the three major synthetic fibers. Because of its relatively cheap price, strong and durable, good elasticity, not easy to deform, corrosion resistance, insulation, crisp, easy to wash and dry, etc., it is deeply loved by people. At present, polyester is the world's largest and most widely used synthetic fiber variety, and polyester accounts for more than 60% of the world's synthetic fiber output. It is widely used in textiles such as clothing, bedding, various decorative fabrics, special fabrics for national defense and other industrial fiber products, such as filter materials, insulating materials, tire cords, conveyor belts, etc. With the continuous and rapid growth of the domestic economy...
