Silk fabric cold pad-batch pretreatment auxiliary

Abstract

The invention discloses a silk fabric cold pad-batch pretreatment auxiliary. The silk fabric cold pad-batch pretreatment auxiliary comprises the following components in parts by weight: 10-25 parts of 8.5% hydrogen peroxide, 10-25 parts of sodium carbonate, 7.5-15 parts of sodium silicate, 40-46 parts of sodium dodecyl benzene sulfonate, 3-5 parts of polyoxyethylene lauryl ether sodium sulfate and 5-10 parts of sodium dodecyl sulfonate. Aiming at the particularity of the silk fabric, the invention provides a cold pad-batch pretreatment auxiliary which is more suitable for the silk fabric. By utilizing the silk fabric cold pad-batch pretreatment auxiliary, the silk fiber damage rate can be reduced to less than 0.6% simultaneously when various sericin impurities are effectively removed.

Description

technical field [0001] The invention relates to a desizing solution for fabric pretreatment. Background technique [0002] Silk is a kind of natural protein fiber. According to the species of silkworm, silk includes mulberry silk, tussah silk, castor silk and cassava silk. Raw silk and its fabrics (called gray silk) contain a large amount of sericin impurities, most of which are inherent sericin (about 20% to 30%) of the fiber material itself, oil wax, ash, pigment, etc. In addition, there are pastes added during silk weaving, coloring dyes applied to identify the twist direction, and various oil stains in the process of operation and transportation. The existence of these natural and artificial impurities not only damages the inherent good quality of silk fabrics and affects the value of clothing, but also makes it difficult for the fabric to be wetted and penetrated by the dye solution, hindering the dyeing and finishing process. [0003] The so-called cold pile pretreat...
