Reeling silk compound additive

Abstract

The invention discloses a reeling silk compound additive, which is prepared from a fluorocarbon surfactant, sulfonated castor oil and polyoxyethylenated castor. The disadvantages of the prior art are overcome, the compound additive is applied to a cocoon cooking process, the influences of the compound additive on the silk reeling result and the cohesive force and the strength of a raw silk are compared and analyzed, the silk reeling result is obviously improved, the mean raw silk grade is improved, the cohesion times is increased, the strength property of the raw silk is slightly improved, and the crystal structure of the raw silk is basically kept invariable.

Description

technical field [0001] The invention relates to the technical field of silk reeling production, in particular to a compound auxiliary agent for silk reeling. Background technique [0002] The process of extracting silk from silkworm cocoons is called silk reeling. Silk reeling is usually boiled. On the one hand, the high temperature of water is used to kill the silkworm pupae in the cocoon. On the other hand, because silk is an animal fiber, it contains a large amount of animal glial protein. By heating, most of the colloidal proteins are dissolved in water, so as to achieve the purpose of separating fibers and smoothly extracting silk. In addition to the fibrous silk fibroin and the sericin glued to the periphery of the silkworm cocoon, it still contains a small amount of oils, pigments, inorganic substances, etc. Among them, oils such as primary alcohols, solid fatty acids, waxes, and liquid fatty acids have water-releasing properties. Therefore, it is necessary to add so...

Problems solved by technology

If the cooked state of silkworm cocoons is adjusted by using the acidity and alkalinity of the above surfactants or organic chemical reagents alone, the goal can indeed be achieved, but there are relatively high requirements for conditions such as temperature, pH value, water hardness, and action parts during use. High, poor acid and alkali resistance, poor stability and other disadvantages, it is easy to cause sericin denaturation, structural damage of silk fibroin and silk protein, excessive cocoon cooking and other negative effects
