Abstract

The invention discloses a blister fastness improver for dyeing polyester and a preparation method of the blister fastness improver. The blister fastness improver comprises the following components in parts by weight: 10-20 parts of a three-terminal allyl cationic monomer, 20-60 parts of an allyl polyether epoxy end cap, 2-6 parts of a cross-linking agent, 0.2-1.0 part of an initiator and 20-50 parts of deionized water. According to the blister fastness improver for dyeing the polyester and the preparation method of the blister fastness improver, the prepared blister fastness improver for dyeing the polyester is a three-dimensional high-molecular cationic polymer with an epoxy active group, is applied to padding and sizing of a dyed polyester fabric, and can improve the blister fastness of the dyed polyester fabric, so that the blister fastness of the dyed polyester fabric is improved, and the service life of the dyed polyester fabric is prolonged. Meanwhile, the polyester fabric is endowed with antistatic property and pilling resistance, and the quality of the polyester fabric is improved.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing auxiliaries, in particular to a water bubble fastness improver for dyeing polyester and a preparation method thereof. Background technique [0002] Polyester is one of the most important types of synthetic fibers. Due to its excellent properties, polyester fiber has become one of the fastest-growing and highest-yielding synthetic fibers. However, at present, polyester is basically dyed with disperse dyes. Since disperse dyes have a relatively simple molecular structure and do not contain ionized groups, sublimation is prone to occur when there is a certain vapor pressure, and the rate of sublimation is proportional to temperature. , which causes the dyed polyester to be affected by the sublimation of disperse dyes when the final product is finalized, and it is prone to serious color fading when the finished polyester fabric is washed with water. Static electricity, often in the settin...
