Abstract

The invention discloses a preparation method of a non-ironing finishing agent for chemical fiber fabric, and relates to the technical field of processing of chemical fiber fabric. The preparation method of the non-ironing finishing agent for the chemical fiber fabric comprises the following steps: (1) putting polyester type polyurethane into a ball mill and performing ball milling; (2) mixing acrylic acid, bisphenol A type epoxy resin, fatty acid diethanolamide and poly(p-phenylformamide) uniformly, performing ultrasonic treatment, shifting to a magnesium chloride solution, performing ultrasonic treatment, cleaning and drying; (3) mixing benzoyl peroxide, sucrose fatty acid ester and pentaerythritol fatty acid ester uniformly, sintering, cooling and performing treatment under saturated vapor pressure; (4) mixing the prepared mixtures uniformly, adding into a mixed solution of ethanol and water, adding sodium sulphite, sodium secondary alkyl sulfate and ammonium hydrogen carbonate, mixing uniformly and adjusting PH to prepare the non-ironing finishing agent. The non-ironing finishing agent can achieve the non-ironing effect, can maintain the original strength, hand feeling comfortability as well as moisture absorbing and air-permeable properties of the chemical fiber, and guarantees the wearing comfortability.

Description

Technical field: [0001] The invention relates to the technical field of chemical fiber fabric processing, in particular to a preparation method for a non-ironing finishing agent for chemical fiber fabrics. Background technique: [0002] Cellulose fiber fabrics are more and more popular due to their good hygroscopicity and wearing comfort. However, due to its own characteristics, cellulose fibers are prone to wrinkling, unevenness and unsightly appearance during wearing and washing. Therefore, after each washing, ironing is required to keep it smooth and crisp, which brings great benefits to people's daily life. A lot of inconvenience came. In order to overcome this shortcoming, people improve by carrying out non-ironing processing to fabric. The usual method is to first impregnate the entire fabric with resin on the tenter frame, and then bake it at a high temperature of 130°C-160°C or stack it at normal temperature to achieve the purpose of non-ironing. After non-ironing...
