The invention belongs to the field of textile material processing, and specifically discloses a viscose dyeing and finishing process, comprising the following steps: S1, placing the viscose base cloth in a cooking pot, mixing water, scouring agent and stabilizer into the cooking pot ; S2, add water to the accelerator to dissolve, inject the accelerator into the cooking pot after fully dissolving, the accelerator is a compound of triethanolamine and sodium carbonate; S3, heat the cooking pot to 50-60°C, inject hydrogen peroxide into the cooking pot In the pot; S4, heating the cooking pot to 80-90°C and running for 50-60min; S5, cooling the cooking pot to 50°C, adding sulfuric acid to the cooking pot to adjust the pH to 6-7. The solution of the present invention can solve the problem that the accelerator NaOH has a strong alkalinity in the traditional process, which will greatly damage the artificial fiber material such as viscose.
Description
Technical field [0001] The present invention belongs to the field of textile material processing, specifically relates to a viscose dyeing and finishing process. Background [0002] Viscose is the main variety of artificial fiber, is made of natural fiber as raw material, alkalizing, aging, sulfonation and other processes to make soluble cellulose xanthanate, and then dissolved in dilute lye to make viscose, made of wet spinning. Viscose is a commonly used non-woven raw material, which has many advantages such as soft feel, smooth and cool, breathable, antistatic and so on. [0003] Dyeing and finishing refers to the textile materials (fibers, yarns and fabrics) to carry out chemical treatment-based process, dyeing and finishing includes pretreatment, dyeing, printing and finishing, of which pretreatment is also known as drifting, the main purpose of which is to remove impurities on textile materials, so that the subsequent dyeing, printing, finishing processing can be carried o...
