Permeation adjuvant for vacuum permeation cocoon cooking

Abstract

The invention relates to a permeation adjuvant for vacuum permeation cocoon cooking, belonging to the technical field of silk reeling appliances. The invention aims at providing a permeation adjuvant for enhancing the permeation in silkworm cocoon shells. The permeation adjuvant is prepared by mixing the following raw material components in percentage by weight: 60-90% of nonionic fabric softenerand 10-40% of fabric finishing agent silicone oil emulsion. The permeation adjuvant for vacuum permeation cocoon cooking is used for reeling silkworm cocoons. A use method for vacuum permeation cocoon cooking comprises the following steps of: controlling water temperature at 30-60 DEG C, adding the permeation adjuvant with the weight accounting for 0.05-0.5% of permeation water for cocoon cooking, adding dried cocoons with the weight accounting for 5-10% of the permeation water for vacuum cocoon cooking permeation, and continuing for 1-10 min after vacuum pressure reaches -0.1 Mpa. Cocoons subjected to vacuum permeation by using the permeation adjuvant have the advantages of full cocoon shell permeation, uniform reeling and soft and smooth hand feel, and the influence of cocoon quality differences on silk reeling quality is reduced. Under the same process conditions, the quality of cocoon silk can be improved to the quality grade of 0.3-0.5A grade products.

Description

technical field [0001] The invention relates to a osmotic aid for cocoon cooking by vacuum osmosis, which belongs to the technical field of silk reeling products. Background technique [0002] Silk reeling production is commonly known as silk making. Different cocoon cooking techniques and technical measures are used in silk reeling production, which have a great impact on the quality of reeled silk. Only when cocoons are cooked well can silk be reeled well. my country's automatic silk reeling and cocoon cooking process mostly adopts the technology of vacuum infiltration outside the machine and cooking inside the machine. The cocoons are vacuum infiltrated and absorbed water before being cooked, so that the cooked cocoons can be fully infiltrated and cooked evenly, and the cocoons are fully protected. The outer layer and the cooked middle inner layer can reduce roughness and inner layer fall, and meet the technical requirements of automatic silk reeling technology such as si...

Problems solved by technology

However, due to the many cocoon layers of silkworm cocoons, the resistance to water absorption and penetration is large, and the water absorption and penetration effect of the cocoon layer is small. Therefore, it is usually necessary to rely on experience to master the temperature, pressure, time and flow rate during vacuum infiltration and water absorption. If the temperature of the infiltration part is too high If the temperature is too low, it will easily cause white cocoons and insufficient penetration. If the time is long, the steam pressure will be high, and the cocoons will be easily shriveled. If the time is short, the pressure will be low. infiltration

At present, in order to improve the penetration force between the cocoon layers, some manufacturers add a single ionic fabric softener to the permeation water in the vacuum infiltration process of cocoon cooking. Defects of impurity adsorption in subsequent processes such as re-shaking and drying
