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 cloth dyeing process, comprising the following steps: S1: gray cloth desizing. S2: Gray fabric pre-shrinking; S3: Use a leveling machine to level the finished fabric; S4: Pre-set the leveled fabric, and use a cloth loading machine to import the fabric into the setting machine during the pre-setting process. Pre-setting treatment, the used sizing liquid during setting includes the following parts by weight: 20-30 parts of softening agent; 30-40 parts of disodium hydrogen phosphate; 70-80 parts of plasticizer; 10-30 parts of glyceryl tristearate 20 parts; 30-34 parts of polytetrafluoroethylene particles; S5: carry out alkali reduction treatment on the pre-shaped cloth; S6: carry out the finalizing treatment on the cloth after the alkali reduction is completed; The cloth is dyed; S8: use a setting machine to perform a post-setting treatment on the dyed cloth with a setting liquid; obtain the finished cloth through the above eight steps. The invention has the advantage of improving the setting effect of the polyester cloth.

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...
