Embodiment 1

[0023] A refined method of mechanism of a mechanism of no oxygen, including the following steps:

[0024] (1) Preparation of Jingjing Liquid: Weigh the calculated amount of sodium carbonate, dissolved in water, formulated aqueous solution of sodium carbonate is 0.70 g / L, add a quantity of surfactant JFC, so that the surfactant JFC in the solution The concentration was 0.05% to obtain a refinement.

[0025] (2) Silk silk

[0026] Heat the escaps to 100 ° C and insulation, press 1: 150 bath ratio to the mandies, and continuously heat treatment for 40 min.

[0027] (3) Cleaning

[0028] The silk monsoon was taken out from the refinery, and the first cleaning was carried out with water at a temperature of 80 ° C, and the second cleaning of water was 70 ° C, and finally washed with normal warm water until the pH of the washing liquid tend to neutralize. After drying, get refined silk.

[0029] (3) According to the weighing grant, the refinement rate is measured, and the reference sta...

Embodiment 2

[0037] A refined method of mechanism of a mechanism of no oxygen, including the following steps:

[0038] (1) Preparation of Jingjing Liquid: Weigh the calculated amount of sodium carbonate, dissolved in water, formulated aqueous solution of sodium carbonate is 1.0 g / L, add 0.02% fluorocarbon surfactant, mix well and uniformly .

[0039] (2) Silk silk

[0040] Heat the escaps to 98 ° C and insulation, press 1: 100 bath ratios to the silk, continuous heating treatment of 35 min.

[0041] (3) Cleaning

[0042] The silk monsoon was taken out from the refined liquid, and two cleaning was carried out with water at a temperature of 75 ° C, and finally was cleaned with normal warm water until the pH was neutral drying, and the refined silk was obtained.

[0043] (4) Test the whiteness of the silk stone in the RGB mode in Photoshop.

[0044] As a contrast, the commercially available products such as the same unit (Zhejiang Tongxiang Zhejiang Silkworm Home Textile Co., Ltd.) will be prov...

Embodiment 3

[0050] A refined method of mechanism of a mechanism of no oxygen, including the following steps:

[0051] (1) Preparation of Jingjing Liquid: Weigh the calculated amount of sodium carbonate, soluble in water, formulated aqueous solution of sodium carbonate to 1.50 g / L, add 0.1% surfactant JFC, and mix well after mixing.

[0052] (2) Silk silk

[0053] Heat the escaps to 95 ° C and heat premium, and put the silk tabs ratio of 1:50, continuous heating treatment for 30 min.

[0054] (3) Cleaning

[0055] The silk monsoon was taken out from the refined liquid, and the water was cleaned with water at a temperature of 80 ° C, and then washed with normal warm water to be neutral.

[0056] (4) Determination of refinement rate according to the weighing grant, refer to standard GB / T 24252-2019 "Silk is" Appendix D "Filler Compressed Back Elastic Test Method", test silk-moving compression backlays.

Abstract

The invention provides a hydrogen peroxide-free machine-made silk floss refining method which comprises the following steps: (1) silk floss refining: putting silk floss pieces into a refining solution, heating, keeping the temperature at 90-100 DEG C, treating for 30-40 minutes, and taking out; the refining liquid contains 0.7-1.5 g / L of sodium percarbonate and a surfactant with the mass concentration of 0.01%-0.1%. (2) cleaning: firstly cleaning with hot water at 70-80 DEG C, and then cleaning with normal-temperature water until the pH value is neutral; the prepared silk floss is high in whiteness, soft and fluffy in hand feeling and excellent in compression resilience; hydrogen peroxide does not need to be used, potential safety hazards of hydrogen peroxide in the transportation and use process are avoided, pollution to the environment is reduced, and the safety of silk floss production is improved.

Description

Technical field [0001] The present invention relates to a refined process of silk, and more particularly to a mechanism-made wireless conventional method without having a hydrogen peroxide. [0002] technical background [0003] Monclain is a melody that is processed with a shelf under the foot (such as the coat, spit, cockroaches), double palace, secondary or ordinary silkworm cocoons. Often as a quilt, the filler of the clothes, with excellent warmth, breathable hygroscopic, anti-mildew resistance, flexibility, human affinity, etc. Silcone is used as a raw material with natural silk fibers, and it is hand-made, and the fibers are formed between the fibers, the intrinsic structure is extremely air, the thermal conductivity is extremely small, the heat-insulating performance is good, the gas permeability is twice the down. The warmth is 3 times higher than that of cotton and chemical fiber, water vapor and carbon dioxide can be freely circulated, comfortable and comfortable, and r...
