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...
