Embodiment 1

[0051] A processing method for polyester fabrics, including the following steps:

[0052] (1) Polyester fabric alkali reduction pretreatment: the use of polyester fabric, the first fabric alkali reduction pretreatment, alkali reduction pretreatment process, the addition of tea saponin and sodium lignosulfonate, in order to ensure a certain amount of alkali reduction at the same time to reduce the amount of sodium hydroxide, reduce the alkalinity of wastewater.

[0053] Process:

[0054]In turn, 15g of sodium hydroxide, 1g of O1g, 10g of sodium lignosulfonate, 25g of tea saponin, add 949mL of water at room temperature under 300 rpm / min stirring for 30min to prepare the pretreatment finishing solution. Then put the polyester fabric into the pre-treatment finishing solution and put it into a 40 °C constant temperature water bath pot for 15 min, then heat up to 95 °C at 3 °C / min, continue to process for 45 min, and finally clean in water, add 2 mL of acetic acid to clean again, and ...

Embodiment 2

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

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

[0078]

[0079] As shown in Table 2:

[0080]With the increase in the use of sodium hydroxide, sodium lignosulfonate and theophynosin, the rate of reduction and loss of strength also gradually increased. In general, the amount of sodium hydroxide is between 5 and 25g / L in polyester fabric alkali reduction treatment; with the increase of sodium hydroxide concentration, after the concentration of sodium hydroxide is greater than 20g / L, the strong damage to the fabric is larger. Comprehensive selection: When the NaOH concentration reaches 15g / L, sodium lignosulfo...

Embodiment 3

[0082] The preparation method is the same as Example 1, the difference is: adjust the amount of modified copper / polyacrylate emulsion in the modified paste, test the K / S value of the fabric, wash fastness, friction color fastness and other properties, as shown in Table 3.

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

[0084]

[0085] As shown in Table 3:

[0086] The addition of modified copper / polyacrylate emulsion to the modified paste allows the fabric to obtain good color, while the fabric has excellent washability and friction color fastness.

Abstract

The invention discloses a processing method of polyester fabric, which belongs to the technical field of imitation silk fabric processing, and is characterized in that it comprises the following steps: (1) pre-treatment of polyester fabric for alkali weight reduction: using polyester fabric, firstly carry out pre-treatment of fabric alkali weight reduction Treatment; (2) Preparation of modified paste; (3) Thermal transfer printing of polyester fabric: using thermal transfer printing process, the prepared modified paste is used to treat the transfer printing paper first, and then inkjet printing the pattern of Adeles Transfer printing to the polyester fabric on the transfer paper to obtain the polyester fabric imitating the Adelaide silk style; the present invention improves the pre-treatment process of alkali weight reduction, optimizes the configuration of the modified paste and the printing process, and prepares the polyester fabric , has the style of imitating Idle Lace, can replace Idle Lace, and has good color, hand feeling and washing fastness.

Description

Technical field [0001] The present invention relates to a processing method of a fabric, more particularly to a processing method of a polyester fabric. Background [0002] Silk fiber has the reputation of "fiber queen" and has a history of more than 5,000 years in China. Silk fiber has a soft feel, elegant luster, while moisture absorption and breathability is excellent; but silk fiber is expensive, dyed silk products are not resistant to washing, poor washing fastness, high maintenance and maintenance costs, easy to age and yellow. [0003] Adlais means "tie-dye", using China's ancient hand-tied warp dyeing process, according to the requirements of the pattern, in the warp knot, layered dyeing, warp, weaving, bright colors, rich patterns, is the symbol of Xinjiang's ancient civilization, its fabric feels soft and smooth, colorful, comfortable to wear, is still the favorite of ethnic minority women in Xinjiang. Traditional handmade Adelex silk has the problems of complicated pro...
