Problems solved by technology

The scouring agents used can be roughly divided into two categories: one is soap or the scouring agent with soap as the main component, but this kind of scouring agent generally has the disadvantages of being not resistant to hard water and easy to yellow; the other is synthetic A scouring agent made of detergent and buffer alkali agent, but this type of scouring agent also has problems such as poor penetration and high foaming

Abstract

The invention discloses a scouring agent for a silk fabric and an application method of the scouring agent. The scouring agent is prepared from the following components in parts by weight: a liquid A, including 100 parts of potassium octyl diphenyl ether disulfonate, 20-40 parts of octadecyl alcohol polyoxyethylene ether, 8-12 parts of sodium diethylhexyl sulfosuccinate, 2-5 parts of a chelating dispersant and 4-6 parts of propargyl alcohol, and a liquid B, including 10 parts of papain and 80-110 parts of a buffering agent. The invention further provides an application method of the scouring agent for the silk fabric. The scouring agent is relatively low in reaction temperature, mild in pH and good in scouring effect. The scouring agent is capable of preventing the fabric from being damaged, and the fabric is capable of maintaining relatively good hand feeling and improving the commercial value of the silk fabric.

Description

Technical field: [0001] The invention relates to the textile field, in particular to a scouring agent for silk fabrics and a using method thereof. Background technique [0002] Silk fabrics need to be scoured before printing and dyeing to remove sericin and other impurities on the surface of the silk, so that the silk can present a white, bright appearance and soft feel. Compared with sericin, the content of other impurities in silk is lower and easy to remove, so the refining process of silk can be regarded as the peptide bond of sericin is broken through hydrolysis or enzymatic reaction, so that sericin can be Dissolving or dispersing in water has achieved the purpose of separating from silk fibroin. [0003] Since sericin is water-soluble but silk fibroin is insoluble in water, under certain physical or chemical conditions, sericin can be dissolved and separated from silk fibroin. At present, the widely used silk scouring methods include water extraction method, soap sc...
