Milk protein fiber or its filament or its blended yarn dyeing method and coloured woven fabric producing method

Abstract

The invention discloses a manufacturing method of milk protein fiber or filament or blended yarn dyeing and yarn-colored product, which is characterized by the following: changing coiling density of yarn; controlling heating temperature; adopting segmented contraction in the cylinder yarn dyeing course; adding self-producing milk protein fiber dyeing specific adjuvant; utilizing polyacrylonitile or polyvinyl acetate alcohol as carrier realize active dyeing technology of milk protein fiber; solving the difficulties of flower color, weak color and bad fastening degree problem to produce excellent washing shrinkage and stable size yarn-dyed product through weaving, shrinking and softening and final disposal.

Description

technical field [0001] The invention relates to a production method of milk protein fiber or its filament or its blended yarn dyed and yarn-dyed products, in particular to a milk protein fiber and its filament and its doubling, twisting, core-spun yarn or its short The invention discloses a method for producing fiber blended yarn dyeing and yarn-dyed products, belonging to the technical field of yarn dyeing and yarn-dyed products production and weaving. Background technique [0002] Milk protein fiber and its filaments are high-grade new fiber materials. It combines the advantages of various natural protein fibers and chemical fibers. Excellent mechanical properties; good spinnability; compatibility with other fibers; not afraid of moths; antibacterial, antibacterial, health care and other properties as one. However, the immaturity of milk protein fiber dyeing technology restricts and hinders its application and promotion in the textile industry. [0003] At present, there...

Problems solved by technology

However, due to the large capacity, small liquor ratio, energy saving, low consumption, and production cost reduction technology used in production, no matter what kind of dye is used for dyeing, it is very easy to have color flower, color difference, low dyeing rate, and color fastness. Degree difference etc.

Therefore, it is not very important to choose the loose fiber dyeing commonly used in the wool spinning industry for problems such as color patterns, color differences, different colors and heat shrinkage of fibers, or add no more than 20% milk protein fibers in a low proportion when blending and then mix with natural fibers. Fiber, regenerated cellulose fiber, synthetic fiber, etc. are blended or interwoven, leaving blank or not considering the dyeing performance of milk protein fiber. The disadvantage of this production process and production method is that it cannot produce high-proportion and pure milk protein fiber products. , cannot fully reflect the excellent performance of milk fiber; seriously affect the color fastness indicators of the product and the brightness of the color, the saturation of the dyeing, the uniformity of the color and the same color; the hand feel cannot be fully utilized, which is easy to cause softness , drapability, and elasticity are very poor

Therefore, no matter what kind of milk protein fiber and which kind of dye is dyed, in addition to choosing a reasonable production process, the occurrence of color flower, color difference, poor color fastness, and unstable size are the dyeing and hindering the application of milk protein fiber in the textile industry.
