Problems solved by technology

For polyester fabrics, if the heat setting temperature is too high to achieve the setting effect, the fabric will have yellowing and brittle defects; and when the temperature is lowered, the setting effect of the fabric cannot meet the requirements.

Embodiment 1

[0054] refer to figure 1 , the dyeing process of a kind of polyester cloth disclosed by the invention, comprises the following steps:

[0055]S1: Gray cloth desizing; S2: Gray cloth pre-shrinking, soaking the gray cloth in clean water, and drying at 120-130°C; S3: Smoothing the finished cloth with a skin pass machine. Titanium dioxide hydrosol is added during the leveling process; S4: Pre-setting the flattened fabric. During the pre-setting process, the fabric is imported into the setting machine equipment for pre-setting treatment using a cloth loading machine. The pre-setting temperature is set at 185°C-190°C , the setting time is 45-60s; the first auxiliary agent is added in the process of putting on the cloth, and the first auxiliary agent includes the following components in parts by weight: 20 parts of sodium dodecylbenzenesulfonate; 3 parts of ammonium salt; 15 parts of sodium bicarbonate; 80 parts of water. S5: carry out alkali reduction treatment on the pre-set clot...

Abstract

The invention discloses a polyester fabric dyeing process which includes the steps: S1 gray fabric desizing; S2 gray fabric pre-shrinking; S3 leveling a post-set fabric by a leveler; S4 presetting theleveled fabric, guiding the fabric into a setter by a fabric feeder in the presetting process and performing presetting treatment; S5 minimizing alkali of the preset fabric; S6 performing medium setting treatment on warp yarns of the alkali minimized fabric; S7 dyeing the medium set fabric; S8 performing post-setting treatment on the dyed fabric through setting liquid by the setter to obtain a finished fabric. The setting liquid for setting comprises, by weight, 20-30 parts of softening agents, 30-40 parts of disodium hydrogen phosphate, 70-80 parts of plasticizers, 10-20 parts of glyceryl tristearate and 30-34 parts of polytetrafluoroethylene particles. The polyester fabric dyeing process has the advantage that polyester fabric setting effects are improved.

Description

technical field [0001] The invention relates to the technical field of cloth dyeing, in particular to a dyeing process of polyester cloth. Background technique [0002] After the fabric is formed from weaving, it usually needs to go through a certain process of dyeing and finishing before it can become a finished fabric that can be used to make various daily necessities. Dyeing and finishing is mainly to dye the fabric, adding additives during the dyeing process, so that the fabric can obtain the effect of finishing while dyeing. [0003] The existing dyeing and finishing process mainly includes the steps of gray cloth pre-shrinking, pre-setting treatment, desizing, alkali weight reduction, mercerizing, dyeing, and setting. In the setting step, heat setting is usually used to set the cloth. For polyester fabrics, the heat setting temperature to achieve the setting effect is too high, which will cause the cloth to produce yellowing and brittle defects; and when the temperatu...
