Abstract

The invention discloses a preparing method of a terylene blended fabric dyeing solution. The preparing method includes the following steps that (1), deionized water is added into mixed powder of cobaltous sulfate, ferrous sulfate and anhydrous sodium sulphate, the mixture is stirred for 0.5-1.5 h while the temperature is kept at 30-55 DEG C; (2), glycerinum is added into the material obtained in the step (1) and mixed uniformly, then 4,4'-oxydiphthalic dianhydride, polyoxyethylene alkyl ether, trimethylolpropane, acetanilide and disodium edetate dehydrate are added and treated for 1.5-4 h while the temperature is kept at 40-65 DEG C; (3), the catalyst, the modifier, the diffusant and the surfactant are added into the material obtained in the step (2), and an ultrasonic reaction is carried out for 0.5-2 h while the temperature is kept at 25-40 DEG C. The dyeing solution prepared through the preparing method is capable of reducing dyeing temperature of terylene blended fabric to achieve low-salt dyeing, improving dye-uptake rate, levelling property and color fastness of the terylene blended fabric and improving the softness, antistatic property, yellowing resistance and bactericidal activity of the fabric.

Description

technical field [0001] The invention relates to the technical field of textile fabric treatment, in particular to a method for preparing dyeing liquid of polyester blended fabric. Background technique [0002] At present, most of the fabrics commonly used in textile fabrics on the market are mainly cotton, polyester, nylon and regenerated cellulose fibers. Although these fabrics can basically meet people's needs, there are also some shortcomings. For example, polyester fabric has good heat resistance, but its hygroscopicity is poor and static electricity is serious, mainly because polyester fiber is a hydrophobic fiber with a tight structure, there is no specific dyeing group in the molecule, and it lacks hydrophilicity. The degree of expansion is low, which brings certain difficulties to dyeing. [0003] In recent years, with the continuous emergence of new fibers, multi-fiber composite fabrics are more widely used, such as polyester and wool, silk, acetate fiber, spandex ...
