Problems solved by technology

The traditional two-bath two-step process has complicated procedures, long process time, energy consumption such as water, electricity, coal, and high cost of additives. More importantly, the caustic soda/sulfuric acid used in the R/C reduction cleaning process after dyeing and washing, Non-green and environmentally friendly, and extremely unfavorable to wastewater treatment
Specifically speaking, sodium hydrosulfite has the following disadvantages: (1) hydrosulfite will spontaneously ignite, especially after absorbing moisture, it will naturally heat up and burn, and the warehouse where the hydrosulfite is placed repeatedly burns to form a fire, which brings serious safety hazards to the fa

Abstract

The invention discloses a polyester fibre and blended dye cleaner and application, which comprises the following parts: castor oil oxirane condensate, isomeric tridecaliphatic alcohol polyoxyethylene ether, Na2SiO3, polycarboxylate derivative, PVP and citrate. The invention can realize one-bath dyeing, detergent and washing to save manufacturing time, water, energy, steam and adjuvant, which improves the thermal transition washing staining fastness by 1-2 grade to improve the product quality.

Description

technical field [0001] The invention relates to a detergent, in particular to a detergent for polyester and its blended dyes. Background technique [0002] During the printing and dyeing process of disperse dyes used in dyeing polyester and its blended fabrics, blended fabrics (cotton, nylon, spandex) are often stained and dyes are thermally migrated at high temperature, and the washing fastness is obviously reduced, which is extremely troublesome in the dyeing and finishing industry. problem. [0003] The traditional dyeing process of T / C blended fabrics is: disperse / reactive dye two-bath two-step process. That is, first use disperse dyes to dye polyester under weak acidic conditions, and after dyeing polyester, use caustic soda / sulfur powder to reduce and clean, destroy and clean the floating color on the surface of polyester fibers and disperse dyes stained on cotton components, and improve the washing fastness. Degree, then neutralize caustic soda with acetic acid, dye...
