Problems solved by technology

[0004] The problem to be solved by the present invention is to provide a polyester-cotton blended yarn sizing device and its process, which solves the problem that the size is difficult to combine with the yarn in hot melt, and uses esterified starch and urea starch instead of PVA to reduce the size of the size. Difficult to handle, the prepared flame-retardant hot-melt adhesive for aluminum-plastic pipes has excellent performance indicators, meeting application requirements and environmental protection requirements

Abstract

The invention relates to a polyester-cotton blended yarn sizing process. The components of the slurry include 50-60 parts by weight of acrylamide grafted starch, 50-60 parts of urea starch, 45-55 parts of ammonium peroxodisulfate viscosity reducer, 1-3 parts of glycerin, 2-3 parts of antistatic agent, by winding the polyester-cotton blended yarn on the guide wheel, using the guide wheel to pull the polyester-cotton blended yarn to the sizing room, so that each section of yarn is in the slurry After dipping for 8 minutes, the ultrasonic generator continues to oscillate, and the impurity removal device is pressed tightly on the polyester-cotton blended yarn, so that each yarn is embedded in the sawtooth depression of the impurity removal part, so as to achieve the effect of removing hairiness on the polyester-cotton blended yarn . The polyester-cotton blended yarn sizing process using acrylamide grafted starch and urea starch has a sizing rate of >14%, and the polyester-cotton blended yarn sizing device is used for production, and the hairiness reduction rate is >90%.

Description

technical field [0001] The invention belongs to the field of adhesive production methods, in particular to a polyester-cotton blended yarn sizing device and a process thereof. Background technique [0002] In the past ten years, the price of raw cotton as natural cellulose is relatively high, while polyester as synthetic fiber is relatively cheap. It is against this background that polyester-cotton fabrics have been produced and developed by leaps and bounds. This type of fabric is often Using PVA as the main slurry, at the same time adding a certain proportion of modified starch and acrylic slurry, and then making a mixed slurry formulation for sizing. Due to the high content of PVA in the mixed slurry formulation, the slurry is easy to crust, foam, and dry. When skeining, the larger resistance of the yarn splitting causes the serosal film to rupture and produce secondary hairiness, which seriously affects the output and quality of the fabric. [0003] The Chinese patent w...
