Novel dyeing and finishing processing technology of micro polyester fabric

Abstract

The invention relates to a novel dyeing and finishing processing technology of a micro polyester fabric. The novel dyeing and finishing process disclosed by the invention is characterized by comprising the following steps of: (1) pretreatment, namely carrying out cold rolling and stacking processing comprising three stages, namely cold stacking, hot alkali treatment and high efficiency washing, on polyester gray fabric; (2) presetting, namely carrying out high temperature tentering and presetting on a pretreated fabric white body by utilizing a setting machine; (3) dyeing, namely dyeing the preset fabric white body by adopting superfine fiber leveling agent; and (4) cleaning, namely carrying out cleaning post-processing on the dyed fabric to remove disperse dyes which are not set after fibres are dyed. According to the novel dyeing and finishing processing technology disclosed by the invention, an environment-friendly and low-energy-consumption cold rolling and stacking pretreatment technology is used for carrying out pretreatment on the micro polyester fabric, on one hand, desizing effect is good and good dyeing and finishing processing conditions are provided for dyeing, and on the other hand, crease mark of the fabric can be effectively reduced; meanwhile, a formula of a dyeing process additive can be adjusted, albafluid U is added to reduce fabric dyeing scratch, and dyeing defects can be prevented from being caused.

Description

technical field [0001] The invention relates to a method for printing and dyeing cloth, in particular to a method for processing polyester imitation silk printed silk. Background technique [0002] Polyester fiber is the most consumed synthetic fiber in the world today. Polyester microfiber is widely used in fashion fabrics. The monofilament linear density of superfine polyester is much lower than that of conventional polyester fiber, which endows it with excellent clothing properties different from conventional polyester fiber, such as moisture absorption, breathability, soft and plump hand feeling , It is full of elasticity, fluffy and elegant, etc., and it is loved by people. However, ultra-fine polyester has the characteristics of small fiber radius, its own structure, especially the irregular shape of the cross section, and the surface is not smooth enough. In addition, during the dyeing process, the friction between the fabric and the mechanical metal parts, the conta...

Problems solved by technology

However, ultra-fine polyester has the characteristics of small fiber radius, its own structure, especially the irregular shape of the cross section, and the surface is not smooth enough. In addition, during the dyeing process, the friction between the fabric and the mechanical metal parts, the contact friction between the fabric and the fabric It is easy to cause fabric wrinkles, and even affect the overall dyeing quality
