Pulp coolant for cotton spinning and wool spinning fibers

Abstract

The invention provides pulp coolant for cotton spinning and wool spinning fibers. The pulp coolant contains emulsifier TX-40, emulsifier EL-40, fatty alcohol-polyoxyethylene ether, coconut diethanol amide, PEG-6000, methyl acrylate, acrylic acid, acrylamide, ammonium persulfate, potassium peroxodisulfate, water and diethanol amine. The emulsifiers TX-40 and EL-40, the fatty alcohol-polyoxyethylene ether, the coconut diethanol amide, the PEG-6000, the methyl acrylate, the acrylamide and water are mixed and heated to 65 DEG C for 3 hours and then cooled to 30 DEG C, and a target product is obtained by adding the diethanol amine to regulate the PH value to 6-7. The product has excellent permeability and antistatic property, is applicable to cotton spinning and chemical spinning, and is also applicable to all wool and wool blended yarns; weaving performance of thin yarns is improved, flyings, adhesion and skips during the weaving process are reduced, strength of single yarns and strength of under-twisted yarns are improved, the product is convenient to use, contains no APEO or phosphorus and is green, and the product is easy to wash after weaving.

Description

technical field [0001] The invention relates to a sizing material for textile warp yarns, in particular to a high-efficiency cold sizing material suitable for sizing pure wool and wool blended yarns, such as cotton spinning wool spinning chemical fibers. Background technique [0002] The warp yarn is an integral part of the shed. During the weaving process, due to the friction between the warp yarn and the heald, steel reed, and warp stopper (in the process of warping, the friction between the warp yarn and the tension device, the split reed, and the fixed width reed) The repeated friction of other parts, as well as the action of beating-up movement in the shedding movement, bears continuous stretching, impact and twists and turns. The fibers on the warp yarn are easily abraded and hairy, and gather and entangle with each other, resulting in unclear shed opening. , causing warp yarn breakage and increased weaving defects, the purpose of sizing the warp yarn is to reduce hair...

AI Technical Summary

Problems solved by technology

Due to the unique physical and chemical properties of wool fiber itself, wool yarn sizing is different from general cotton yarn sizing. It has the following problems: 1) There are scales on the surface of wool fiber and wool contains oil, plus the wool and wool oil applied in spinning cause wool Wettability is poor, which reduces the affinity between the polymer in the slurry and the macromolecules of the wool fiber, which may easily cause insufficient penetration and shedding of the serous film; 2) The elongation at break of the wool yarn is generally large, and the wool fiber is elastic. The elongation at break of the serous film is small, and the elongation at break of the yarn after sizing is smaller than that of the original yarn; 3) The fineness of wool fiber is relatively thick and the elasticity of wool fiber itself is large, so the hairiness on the surface of wool yarn is not easy to fit when sizing; 4) Wool is a natural protein fiber , is sensitive to high temperature, alkali and strong mechanical action, so it is not suitable to use high-temperature long-term soaking and strong rolling for sizing; 5) If the fabric is not well desized, the fabric will be hard and inelastic, making Woolen fabric loses its original style
