Novel sizing agent for sizing terylene or terylene staple fiber

Abstract

The invention provides a novel sizing agent for sizing terylene or terylene staple fiber. The novel sizing agent comprises the following components in parts by mass: 35 to 40 parts of polyving akohol, 35 to 40 parts of potato starch, 45 to 55 parts of phosphate starch, 10 to 20 parts of crylic acid, 0.5 to 1.5 parts of wax sheets, 1 to 2 parts of antistatic agent and 1 to 2 parts of softening agent. The novel sizing agent has the advantages of easy desizing, stable viscosity, no pollution and low material cost and is beneficial to large-scale production.

Description

technical field [0001] The invention relates to a size used for sizing textiles, in particular to a new type of size for sizing polyester or polyester staple fiber. Background technique [0002] Warp yarns that use chemical fibers as raw materials generally need to be sized, that is, a special adhesive is applied to the surface of the warp yarns to produce a film that does not make the surface of the yarn hairy, so that the hairiness protruding from the yarn around the yarn adheres to the evenness of the yarn. , increase the smoothness of the warp yarn, thereby reducing the breakage of the warp yarn during the weaving process, thereby reducing the number and time of loom stoppages. However, if the warp yarn is too strong, it will increase the breakage rate, because too much size penetrates into the yarn, and when the yarn is subjected to external force, the adhesion between the fibers is too strong, which will cause the yarn to lose its extensibility and elasticity and becom...
