Abstract

The invention discloses a desizing agent for a synthetic fiber. The desizing agent consists of the following components in parts by weight: 3-6 parts of sodium hydroxide, 10-20 parts of alkylphenol polyoxyethylene, 10-20 parts of ethanol, 1-3 parts of sodium hexametaphosphate, 1-3 parts of potassium chloride, 10-20 parts of fatty alcohol, 5-8 parts of polyvinylpyrrolidone, 1-3 parts of methylcellulose and 120-160 parts of water. Compared with the prior art, the desizing agent has the beneficial effects of good desizing effect, suitability for desizing under various conditions, ready availability of raw materials, simple preparation process and low cost.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing auxiliaries, and more specifically relates to a desizing agent for synthetic fibers. Background technique [0002] The size on synthetic fabrics is usually polyester, polyacrylate, etc., and waxes, mineral oils, esterified oils, and nonionic surfactants are also added. [0003] There are many kinds of polyester and polyacrylate sizing used, and their properties are different, but they can all be hydrolyzed under alkaline conditions. Therefore, the alkali agent is the main component of the desizing agent. Now commonly used desizing agents all have disadvantages such as relatively complicated preparation process, mediocre use effect, and relatively limited use range. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a desizing agent for synthetic fibers. [0005] To achieve the above object, th...
