Problems solved by technology

[0003] As CN104611771B discloses a kind of mulberry silk fiber oil-removing and glue-preserving process, the sericin residual rate is about 4.8%, the breaking strength is about 3.47-4.66cN / dtex, and the oil content is about 0.42-0.48%, but the higher sericin content , it will affect the luster of silk fibroin and the processing of silk fiber, and the oil, wax and other impurities contained in sericin will bring certain difficulties to post-processing. In addition, in order to facilitate silk degumming, silk fibroin is generally The sericin in the outer layer is pre-soaked with sodium carbonate solution to expand the sericin, and then the subsequent degumming is carried out. The technical scheme disclosed in CN104611771B requires pre-soaking for 12 hours, and subsequent steps are required to remove oil and protect the gum. The processing steps are cumbersome

Abstract

The invention proposes a mulberry silk refining agent and a processing method of mulberry silk. The mulberry silk refining agent comprises the following raw materials in parts by weight: 0.8-1.8 parts of sodium carbonate, 3.3-4.8 parts of sodium lignosulfonate, 0.6-1 part of Isotridecanyl ethoxylate, 0.2‑0.6 part of citric acid and 0.05‑0.15 part of silica with a particle size of 30‑50 nm. The invention not only retains relatively low residual glue rate and residual oil rate, but also ensures good mechanical strength and bulkiness of silk.

Description

technical field [0001] The invention relates to the technical field of mulberry silk processing, in particular to a mulberry silk refining agent and a processing method for mulberry silk. Background technique [0002] In the printing and dyeing process of mulberry silk, in order to maintain the smooth touch and high quality of mulberry silk, the mulberry silk fabric must be refined for the purpose of degumming. The composition of sericin mainly includes the following components: silk fibroin 70-80%, sericin 25-30%, plain color, wax, carbohydrate 0.7-1.5% and inorganic matter 0.5-0.8%, among which sericin is composed of three layers Or composed of four layers of sericin with different solubility. Pigment, oil wax and inorganic substances mainly exist in sericin. When silk is degummed, if the degumming is excessive, it will damage the silk fibroin, resulting in insufficient pulling force of the silk, and the silk is brittle and easy to break. The advanced silk degumming proce...
