Problems solved by technology

[0002] In the weaving process of textiles, the warp yarns must be sized. The sizing of cotton and polyester-cotton fabrics is generally polyvinyl alcohol (PVA) and its mixture. The water solubility of polyvinyl alcohol (PVA) commonly used for sizing is very poor. Agglomeration is prone to occur, therefore, neither hot water desizing nor light alkali desizing can obtain good results

Abstract

The invention discloses a multifunctional oxidizing desizing agent. The multifunctional oxidizing desizing agent is prepared by the following components in parts by weight: 3 to 5 parts of potassium peroxodisulfate, 1 to 3 parts of sodium bromite, 4 to 6 parts of sodium alkyl sulfate, 10 to 20 parts of fatty alcohol-polyoxyethylene ether, 1 to 3 parts of lauryl sodium sulfate, 1 to 3 parts of zinc stearate, 5 to 8 parts of polyacrylic acid, 1 to 3 parts of hydroxymethyl cellulose, 3 to 6 parts of phosphorous acid, and 80 to 100 parts of water. The multifunctional oxidizing desizing agent disclosed by the invention has a good effect of desizing, is suitable for various sizes, has a desizing effect on a plurality of mixing sizes, and is high in desizing efficiency; and the multifunctional oxidizing desizing agent has favorable stability to strong base bath.

Description

Technical field [0001] The invention belongs to the technical field of textile printing and dyeing auxiliary agents, and more specifically relates to a multifunctional oxidizing desizing agent. Background technique [0002] In the weaving process of textiles, warp yarns must be sizing. Cotton and polyester-cotton fabrics are generally sizing with polyvinyl alcohol (PVA) and their mixtures. Polyvinyl alcohol commonly used for sizing has poor water solubility. Agglomeration is easy to occur, therefore, neither hot water desizing nor light alkali desizing can achieve good results. [0003] The use of PVA and oxidizing agent can cause oxidative degradation of macromolecules into low-molecular compounds that are easily soluble in water, with high removal efficiency and rapid operation, thereby achieving the effect of desizing. Summary of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a multifunctional oxidizing de...
