Problems solved by technology

In comparison, cotton fiber and polyester fiber are easier to dye, so the blended fiber of polyester and cotton is easy to cause color difference between fibers, especially light color is more obvious. The damage to the environment is relatively large, so it is necessary to study a salt-free printing and dyeing auxiliary agent for blended fibers and its preparation method

Abstract

The invention discloses a salt-free printing and dyeing additive applied to a blend fiber. The salt-free printing and dyeing additive comprises ethylene glycol monobutyl ether, sodium carboxymethyl cellulose, alkyl phosphate monoalkyl ester, rhamnose, polyxyethylated alkylphenol and water. When used, the salt-free printing and dyeing additive applied to the blend fiber can completely replace inorganic salt in the printing and dyeing process of natural plant dye, which is beneficial to environmental protection; meanwhile, by adding the alkyl phosphonic acid monoalkyl ester, the salt-free printing and dyeing additive can make the coloring effect of the cotton-polyester blend fiber good and cannot cause the color difference between a cotton fiber and a polyester fiber.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, in particular to a salt-free printing and dyeing auxiliaries applied to blended fibers and a preparation method thereof. Background technique [0002] The basic component of polyester is polyethylene terephthalate, which is called polyester fiber (PET) because of the large number of ester groups on the molecular chain. The relative molecular weight of polyester used for fibers is generally around 18000-25000. Polyester has a lower molecular weight and industrial polyester has a higher molecular weight. In fact, there are also small amounts of monomers and oligomers present. These oligomers have a low degree of polymerization and exist in a cyclic form. Polyethylene terephthalate can be obtained by polycondensation of terephthalic acid (PTA) and ethylene glycol (EG) through direct esterification to obtain ethylene terephthalate (9BHET). [0003] From the perspective of polyester mol...
