Embodiment 1

[0019] The one-bath dyeing and finishing process of the protein-containing fiber blended knitted fabric described in this embodiment:

[0020] The first step is the refining of silk cotton: since silk cotton contains sericin and fibroin, it is necessary to put the silk cotton in the refining solution, heat it at 2°C / min to 98°C for 60 minutes, and drain the water;

[0021] The second step, glue washing: Since the silk cotton still contains a lot of glue in the aqueous solution after refining, there is still a residue after watering, so it is necessary to remove the remaining glue, so it is necessary to add 80 ~ 90 ℃ to the silk cotton Hot water, then add Pingpingjia O and sodium hexametaphosphate, heat at 2°C / min to 98°C for 25 minutes to release water, the content of Pingpingjia O is 0.8g / L, and the content of sodium hexametaphosphate is 0.5g / L ;

[0022] The third step, neutralization: add 0.3g / ml glacial acetic acid to the above-mentioned silk cotton, heat it to 50°C for 1...

Abstract

The invention discloses a dyeing and finishing technology, and in particular relates to a production technology for dyeing and finishing blended fabrics of protein fibers and plants. The invention aims at providing a single-bath dyeing and finishing process of the blended knitting fabrics containing the protein fibers, which is consistent in dye-uptake rate, good in evenness, and free of flower ash and dyeing effect, and can ensure the color fastness. According to the single-bath dyeing and finishing process of the blended knitting fabrics containing the protein fibers obtained by the invention, silk cotton is dyed by the method, so that the cotton is consistent with real silk in color and has comfortable sensation just as the real silk, and in addition, the cotton has the function of natural moisture absorption, so that the flower ash effect and the uneven phenomenon of a common dye method of the real silk and the cotton are changed; the defect of poor dyeing color fastness of an original process is improved; consumption of water, electricity and gas is greatly reduced; and the single-bath dyeing and finishing process plays roles in saving and reducing emission.

Description

technical field [0001] The invention relates to a dyeing and finishing technology, in particular to a production process capable of dyeing and finishing the blended fabric of protein fiber and plant. Background technique [0002] Silk is a kind of protein fiber, which maintains the nutrition and naturalness of silk fabric. Cotton and flax are plant fibers, which have the characteristics of moisture absorption, breathability and naturalness. Because the two are completely different fibers, the dyeing rate is also completely different. Reactive dyes (vinyl sulfone) are used for one-bath dyeing, so that the cotton fiber and silk protein can achieve the same chroma. [0003] At present, the dyeing rate of ordinary dyeing is not the same, and it is easy to produce colored flowers and gray effects. Through research and development, the dyeing rate of silk and linen cotton can be consistent. Contents of the invention [0004] The purpose of the present invention is to solve the...
