Abstract

The invention discloses a silk degumming method.The silk degumming method comprises the following steps that 1, water is contained in a containing tank, heating is performed to increase the temperature, the temperature is kept at 60 DEG C-90 DEG C, and citric acid and tartaric acid are added; 2, silk or a silk fabric is put into the containing tank, ultrasonic waves are started, the ultrasonic wave frequency is 50-60 KHz, and the treatment time is 20-40 min; 3, washing is performed with water at the temperature of 50 DEG C-70 DEG C and then performed again with water at the temperature of 20 DEG C-30 DEG C.The silk treated through the silk degumming method has the advantages that the breaking strength loss and the breaking elongation loss are both little, and sericin in raw silk is basically removed; the whiteness, glossiness and dyeing property of the silk are improved, and meanwhile the handfeel of the silk is soft and smooth; the silk fabric prepared in subsequent treatment is good in glossiness and handfeel, and the quality of the fabric is improved.

Description

technical field [0001] The invention relates to the field of silk processing, in particular to a silk degumming method. Background technique [0002] Silk is a continuous long fiber formed by the solidification of the silk liquid secreted by cooked silkworms when they cocoon. It is also called natural silk and is a natural fiber. Humans utilized one of the first animal fibers. Silk is the lightest, softest and thinnest natural fiber in nature. It can easily return to its original shape after the external force is removed. The silk quilt is made of high-quality silk, with a novel fiber structure to allow water vapor to circulate freely. Coupled with the unique air permeability and moisture permeability of silk itself, the silk quilt feels smoother, cool but not warm, warm but not dry. Mulberry silk is mainly composed of animal protein, rich in 18 kinds of amino acids necessary for the human body, can promote the vitality of skin cells, prevent vascular sclerosis, long-term...
