Sizing agent for spun polyester thread

Abstract

The invention discloses a polyester yarn sizing slurry, which is made of the following raw materials in weight ratio: 50-75% of wheat protein powder, 7-10% of casein, 5-20% of hydrochloric acid, and 5-10% of sodium hydroxide %, additives 5-10%. The raw materials used in the present invention are all non-toxic and environment-friendly materials, do not use refractory substances such as PVA, have good biodegradable properties and good film-forming properties, and the mechanical properties of the sizing yarns and fabrics are good, and the sizing effect is excellent. excellent.

Description

technical field [0001] The invention relates to a polyester yarn sizing slurry. Background technique [0002] Sizing aims to reduce hairiness and improve wear resistance by using sizing to treat warp yarns, so as to prevent or reduce warp yarn breakage in the weaving process. It is an essential process in the textile industry. At present, the formula of textile size includes main size and auxiliary size. Taking into account the difficulty of sizing and the cost of sizing, the main size used for polyester yarn sizing is mainly PVA, and the auxiliary size is mainly oil for softness and smoothness. Among them, PVA size has always been the preferred material for sizing polyester and polyester-cotton blended yarns. However, PVA has high requirements for pulping conditions. to get slurry. During the cooking process, the energy consumption is large, and the requirements for the cooking equipment are high. Therefore, developing a new size to replace the PVA size is the focus of a...
