Embodiment 1

[0042]refer to figure 1 , a dyeing process of strong-twisted polyester cloth with high color fastness, the polyester gray cloth (hereinafter referred to as gray cloth) is processed in the following steps:

[0043] S1: pre-shrunk. Place the gray cloth in the high temperature and high pressure overflow dyeing machine, and then add caustic soda solution into the high temperature and high pressure overflow dyeing machine for pre-shrinking treatment. The concentration of caustic soda is 5g / L, the temperature is controlled at 120°C, and the duration is 30min. Afterwards, wash 4 times with clean water at room temperature.

[0044] S2: Pre-type. Put the gray cloth pre-shrunk by S1 into the heat setting machine, adjust the temperature in the heat setting machine to 180°C for 5 minutes, and then wait for the gray cloth to cool to 25°C.

[0045] S3: Alkali reduction. The gray cloth after S2 presetting is transported to the alkali weight reduction machine for alkali weight reduction. ...

Embodiment 6

[0055] The difference between Example 6 and Example 1 is that there is no dextran hydroxypropyltrimethylammonium chloride in the raw material of the dye used in S5 dyeing.

[0056] The difference between Examples 7-10 and Example 1 is that the raw materials of the color-fixing agent in S6 washing are as shown in Table 2 in parts by weight: unit: part

Embodiment 11

[0059] The difference between Example 11 and Example 1 is that the raw material of the color-fixing agent in S6 water washing is 40 parts by weight of triethylenetetramine.

[0060] The difference between embodiments 12-15 and embodiment 1 is that the raw materials of the finishing liquid in the S7 setting are as shown in table 3 in parts by weight: unit: part

Abstract

The invention relates to the technical field of polyester fabric processing and discloses a dyeing process of heavy-twist polyester fabric with high color fastness. Gray fabric is treated through steps as follows: S1, preshrinking; S2, pre-setting; S3, alkali peeling; S4, neutralization; S5, dyeing: the gray fabric subjected to neutralization treatment in S4 is dyed, and dye for dyeing is preparedfrom raw materials in parts by weight as follows: 20-30 parts of disperse dyes, 15-25 parts of sodium lignin sulfonate, 200-260 parts of water, 13-17 parts of acetic acid, 17-24 parts of arachidyl glucoside, 10-15 parts of sodium chloride and 60-80 parts of styrene phenol polyoxyethylene ether ammonium sulfate; S6, water washing; and S7, setting: the heavy-twist polyester fabric with high color fastness is prepared after S7 is implemented. Arachidyl glucoside and styrene phenol polyoxyethylene ether ammonium sulfate are added to the dye, so that the color fastness of the dyed polyester fabriccan be improved.

Description

technical field [0001] The invention relates to the technical field of polyester cloth processing, more specifically, it relates to a dyeing process of strongly twisted polyester cloth with high color fastness. Background technique [0002] There are many kinds of polyester cloth, and because of its strong comprehensive performance, it is the most widely used synthetic fiber in textiles. Strong-twisted polyester fabrics have high requirements for the selection of materials, the change of twist and twist direction, the time and temperature of thread setting, the tension and uniformity of weaving threads, etc., and the production has certain technical difficulties. [0003] There are many types of strong-twisted polyester, but they all have common characteristics. One or both sides of the warp and weft combination of polyester fabrics need to add strong twist, and the production method adopts white weaving and half-dyed weaving technology. Gray fabrics require refining, alkal...
