Abstract

The invention discloses a process for treating knitted fabric flat laid on an ironing table for direct pressing and ironing, and relates to the technical field of clothing fabric treatment. The specific process comprises a step (1) of mixing organosilicon monomers with deionized water to obtain organosilicon microspheres through reaction in alkaline environment; a step (2) of adding the organosilicon microspheres to deionized water to react with ammonia and KH560 separately to obtain organosilicon microspheres coated with epoxy functional groups; a step (3) of placing silica sol in a container, and adding the KH560 after regulation of pH, adding water-based polycarbonate and the organosilicon microspheres coated with the epoxy functional groups after reaction to obtain a required fabric treatment emulsion; a step (4) of dipping the knitted fabric in the fabric treatment emulsion, taking out and curing the knitted fabric at constant temperature, and performing hot-press compounding. According to the process, through treatment to the knitted fabric, the defect of easy deformation of the fabric during high-temperature ironing is overcome, and damage to the fabric structure elasticityduring direct ironing is reduced; and the ironing efficiency is improved, and the process has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of clothing fabric treatment, and in particular relates to a knitted fabric treatment process that can be flatly laid on an ironing table and directly pressed and ironed. Background technique [0002] At present, the textile surface used for garment processing is divided into three categories, woven fabrics, knitted fabrics and non-woven fabrics. The first two types of fabrics are processed by weaving yarns or filaments, and the latter type of fabrics are processed by textile fibers through bonding, fusion or other mechanical and chemical methods. Knitted fabrics are formed by forming loops of yarn or filaments with knitting needles, and then interlocking the loops. Due to the coil structure of knitted fabrics, there is more yarn stored per unit length, so the elasticity is better, but the fabrics of knitted fabrics are not easy to take care of. After wearing, they need to be dried at high temperature or ir...
