Problems solved by technology

[0002] With the replacement of chemical fiber products, the recycling of various polyester wastes has become a very urgent issue. However, the pretreatment agents used in ordinary recycling processes have weak decomposition capabilities, large fiber losses, poor dispersion capabilities, and The whiteness of the finished chemical fiber obtained is not enough, which leads to the inability to effectively recycle these wastes and obtain high-quality chemical fiber products

Abstract

The present invention discloses a whitening type chemical fiber auxiliary agent, which comprises, by weight, 10-35 parts of an efficient degreasing agent, 5-25 parts of desizing powder, 1-7 parts of amylase, 2-20 parts of a refining agent, 10-40 parts of a chelating dispersant, 15-35 parts of an oxygen bleaching stabilizer, 5-25 parts of soap oil, 2-18 parts of a fluorescent whitening agent, 1-13 parts of a mercerizing penetrant, and 10-25 parts of tartaric acid. According to the present invention, the whitening type chemical fiber auxiliary agent can effectively improve the whiteness of chemical fiber products, can efficiently remove the degrease from polyester waste, and further has advantages of strong alkali resistance, strong permeability, and strong emulsification; and the synergistic effect can be provided by combining the materials, and the obtained whitening type chemical fiber auxiliary agent is particularly suitable for the pretreatment process of polyester waste so as to obtain the high-whiteness and high-quality chemical fiber product.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a whitening chemical fiber auxiliary agent. Background technique [0002] With the replacement of chemical fiber products, the recycling of various polyester wastes has become a very urgent issue. However, the pretreatment agents used in ordinary recycling processes have weak decomposition capabilities, large fiber losses, poor dispersion capabilities, and The whiteness of the finished chemical fibers obtained is not enough, resulting in the inability to effectively recycle these waste materials and thus fail to obtain high-quality chemical fiber products. Contents of the invention [0003] The object of the present invention is to provide a whitening chemical fiber auxiliary agent to solve the deficiencies of the prior art. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a whitening che...
