Embodiment 1）

[0023] The cationic dyeable polyester fabric dyeing and finishing process of this embodiment has the following steps:

[0024] ① Immerse the cationic dyeable polyester fabric in the dye solution, add acid to adjust the pH to 4.5, and then dye it at 120°C for 30 minutes.

[0025] The dye liquor is an aqueous solution containing 1.4g of refined emulsifier, 0.9g of sedimentation preventive agent, 5.0g of sodium sulfate, 2.0g of ultraviolet absorber and 3.2g of cationic dye per liter; and the total weight of cationic dye is 3.2% of the weight of the fabric .

[0026] Among them, the refining emulsifier used is SEM-35N refined emulsifier produced by Shinshou Chemical Co., Ltd., and its main component is polyoxyethylene nonylphenol ether; the precipitation preventive agent is produced by Jiangsu Dewang Chemical Industry Co., Ltd. Preventive agent HT-77, its main component is fatty alcohol polyoxyethylene ether.

[0027] The ultraviolet absorber used is Hipom UV-330 produced by Suz...

Embodiment 2～ Embodiment 5）

[0037] The dyeing and finishing process of each embodiment is basically the same as that of Example 1, and the differences are shown in Table 1.

[0038] Table 1

[0039]

[0040] Among them, the contact cooling coefficient q max With reference to GB / T 35263-2017 "Testing and Evaluation of Textile Cooling Feeling at Instant Contact", the test conditions are: temperature 20±0.2°C, humidity 65±2%, △T=15°C. The evaluation index is ≥0.15J / cm 2 ·s.

Abstract

The invention discloses a cationic dyeable polyester fabric dyeing and finishing process with composite functions of resisting ultraviolet light, having cool touch and repelling mosquitoes. The cationic dyeable polyester fabric dyeing and finishing process comprises the following steps: (1), soaking the cationic dyeable polyester fabric into a dyeing solution, adding acid to regulate the pH valueto 4.0-5.0, and performing dyeing treatment for 20-60 minutes at a temperature of 110-135 DEG C; (2), performing thermal washing, reduction washing and acid neutralizing on the fabric in sequence; and(3) dehydrating and drying the fabric, and padding after-finishing liquor, and finally roasting and shaping. The process selects a special ultraviolet-light absorber for cationic dyeable polyester fabric, simultaneously performs anti-ultraviolet functionalization and dyeing, only performs mosquito repelling and cooling functionalization for finishing link, can obtain relatively good ultraviolet light resistance through a special functional treatment way, and finally enables the cationic dyeable polyester fabric to have three functions of relatively good ultraviolet light resistance, cool touch and mosquito repelling.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a dyeing and finishing process of cationic dyeable polyester fabric with combined functions of anti-ultraviolet rays, cool touch and anti-mosquito. Background technique [0002] With the increasing maturity of the functional processing technology of textile fabrics, the requirements for the functions of textile fabrics are also getting higher and higher. Single-functional textile fabrics can no longer meet the needs of specific fields, and there is a broad market for composite functional textile fabrics. [0003] There are two main ways to functionalize fabrics: [0004] (1) Prepare functionalized fibers first, and then prepare functionalized fabrics. [0005] This approach is mainly applicable to chemical fibers, and has the advantage of better functionalization effect, but the disadvantage of higher requirements for process equipment and higher...
