Embodiment 1

[0051] A kind of processing method of polyester fabric, comprises the following steps:

[0052] (1) Pre-treatment of polyester fabrics for alkali weight reduction: use polyester fabrics, firstly carry out pre-treatment of fabrics for alkali weight reduction. At the same time reduce the amount of sodium hydroxide and reduce the alkalinity of wastewater.

[0053] Process flow:

[0054] Sequentially weigh 15 g of sodium hydroxide, 1 g of Pingping O, 10 g of sodium lignosulfonate, and 25 g of tea saponin, add 949 mL of water, and stir at 300 rpm for 30 min at room temperature to prepare a pretreatment finishing solution. Then put the polyester fabric into the pre-treatment finishing solution and put it in a 40°C constant temperature water bath for 15 minutes, then raise the temperature to 95°C at 3°C / min, continue the treatment for 45 minutes, and finally wash it in water, and then add 2 mL of acetic acid to wash it again. Finally, rinse with cold water twice, and dry at 100°C f...

Embodiment 2

[0076] The preparation method is the same as that in Example 1, the difference is that the amount of sodium hydroxide, sodium lignosulfonate and tea saponin used in the alkali weight reduction treatment process and the treatment time (95°C) are adjusted to test the effect of the amount of additives on the weight reduction of polyester fabrics. The influence of rate and strength is shown in Table 2.

[0077] Table 2. Effect of alkali weight reduction process on fabric properties

[0078]

[0079] As shown in table 2:

[0080] With the increase of sodium hydroxide, sodium lignosulfonate and tea saponin, the reduction rate and strength loss rate also gradually increased. In general, the amount of sodium hydroxide used for polyester fabric alkali reduction treatment is between 5 and 25g / L; as the concentration of sodium hydroxide increases, when the concentration of sodium hydroxide exceeds 20g / L, the strength of the fabric will be greatly damaged. Comprehensive selection: wh...

Embodiment 3

[0082] The preparation method is the same as in Example 1, the difference being: adjust the consumption of the modified copper / polyacrylate emulsion in the modified paste, and test the effects of the K / S value of the fabric, the washing fastness, the color fastness to rubbing, etc., such as Table 3 shows.

[0083] Table 3. Effect of the amount of modified copper / polyacrylate emulsion in the modified paste on the properties of fabrics

[0084] .

[0085] as shown in Table 3:

[0086] Adding the modified copper / polyacrylate emulsion into the modified paste can make the fabric obtain good color and luster, and the fabric has excellent color fastness to washing and color fastness to rubbing.

Abstract

The invention discloses a processing method of a polyester fabric, and belongs to the technical field of silk-like fabric processing. The method is characterized by comprising the following steps of (1) performing polyester fabric alkali decrement pretreatment: adopting a polyester fabric, and firstly carrying out fabric alkali decrement pretreatment; (2) preparing modified paste; and (3) performing thermal transfer printing on the polyester fabric: treating transfer printing paper with the prepared modified paste by adopting a thermal transfer printing process, then performing ink-jet printing on a Yidelaisi pattern to the transfer paper, and performing transfer printing on the polyester fabric to obtain the Yidelaisi silk-like polyester fabric. By improving the alkali decrement pretreatment process and optimizing the configuration and printing process of the modified paste, the prepared polyester fabric has the Yidelaisi silk-like style, can replace the Yidelaisi silk, and has good color, hand feeling and washing fastness.

Description

technical field [0001] The invention relates to a processing method of a fabric, and more particularly relates to a processing method of a polyester fabric. Background technique [0002] Silk fiber has the reputation of "Fiber Queen" and has a history of more than 5,000 years in my country. Silk fiber has a soft feel, elegant luster, and excellent moisture absorption and air permeability; however, silk fiber is expensive, dyed silk products are not washable, have poor washing fastness, high maintenance and maintenance costs, and are prone to aging and yellowing. [0003] Adeles means "tie-dye". It adopts the ancient hand-tied dyeing process in my country. According to the requirements of the pattern, it is tied on the warp yarn and dyed in layers. The warp and silk weaving are bright in color and rich in patterns. A symbol of Xinjiang's ancient civilization, its fabrics are soft to the touch, bright in color and comfortable to wear, and are still the favorite of ethnic minor...
