Problems solved by technology

However, the methods used to make silk from colored cocoons are: full cocoon cooking, rotting, rinsing, cooking, dehydration, drying, carding, grading, packaging, but the process of silk made from natural colored cocoons is precisely Due to this conventional method, after several processes such as rinsing and cooking, the color will fall off from the cocoon silk and turn white. How to keep the original color when made from natural colored cocoon silk has become a problem that needs to be solved. technical problem

Embodiment Construction

[0015] The present invention will be further described below.

[0016] Take 100 kilograms of natural colored cocoons, first cut the cocoons to remove the pupae in the cocoons, then boil them in a pot for 3 hours at 100°C, cool to room temperature and then rinse them. After softening, boil for 2 hours, rinse after cooling to room temperature, and then dehydrate, dry, card, classify and pack in sequence.

[0017] Take 100 kg of natural colored silkworm cocoons, cut the cocoon to remove the pupa in the cocoon, then put it in a pot and boil it in water at 100°C for 40 minutes, cool to room temperature and rinse, then add neutral protease when the temperature reaches 40°C and keep it at a constant temperature 1 hour, followed by rinsing, dehydration, drying, carding, grading, and packaging.

Abstract

The present invention discloses a method for making natural color cocoon into spun silk. Said method includes the following steps: cutting cocoon and removing pupa, first water cooking, first cooling, first rinsing, secondary water cooking, secondary cooling, secondary rinsing, dewatering, drying and carding, in which the described secondary water cooking is characterized by that in the water cooking process an alkaline swelling agent and a neutral softening agent are added, the cocoon can be cooked until the surface silk gum of the silk is completely dissolved, and the cocoon layer is completely fluffed and can be opened.

Description

technical field [0001] The invention relates to a processing method for keeping the color on the silk firm, in particular to a processing method for keeping the color on the natural colored cocoon firm. Background technique [0002] At present, spun silk is made of white silkworm cocoons and leftovers as raw materials. The spun silk and fabrics made by traditional "opening technology" need to be dyed in order to obtain colored fabrics. Chemical agents contain harmful substances such as azo, organic chlorine and heavy metals. With the continuous progress of the society and the continuous innovation of technology, a kind of silkworm eggs that form colored cocoons has been cultivated. The articles made of silk made of natural colored silk cocoons do not contain harmful substances to the human body. It became a fashion and a consensus, and people gradually demanded this kind of fabric. However, the methods used to make silk from colored cocoons are: f...
