Embodiment 1）

[0024] The cationic dyeable polyester / polyester / spandex fabric dyeing and finishing process of this embodiment has the following steps:

[0025] ① Soak the cationic dyeable polyester / polyester / spandex fabric in the dye solution, add acid to adjust the pH to 4.5, and then dye at 120°C for 30 minutes.

[0026] The dyeing solution is an aqueous solution containing 1.4g of refined emulsifier, 0.9g of precipitation preventive agent, 5.0g of sodium sulfate, 2.5g of water-absorbing processing agent, 2.0g of ultraviolet absorber and 2.55g of cationic dye per liter; and the total weight of cationic dye 2.55% of the weight of the fabric.

[0027] 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 eth...

Abstract

The invention discloses a dyeing and finishing process for a cationic dyeable terylene / terylene / spandex fabric with an anti-ultraviolet, moisture-absorbing and quick-drying and anti-crease combined function, which comprises the following steps: (1) a fabric is soaked in dye liquor, acid is added to regulate pH to 4.0 to 5.0, and dyeing treatment is then carried out under 110 DEG C to 130 DEG C; (2) the fabric sequentially undergoes hot water washing, reduction cleaning and acid neutralization; (3) the fabric is first dewatered, then impregnated with post-finishing solution and finally cured tobe shaped. According to the method disclosed by the invention, anti-crease functionalization is only carried out in the step of post-finishing, while anti-ultraviolet functionalization and moisture-absorbing functionalization are carried out along with dyeing, moreover, aimed at the fabric disclosed by the invention, special moisture absorption processing agent and ultraviolet light absorber areadopted, the special functionalization method can particularly achieve a good anti-ultraviolet function and moisture-absorbing and quick-drying function, and ultimately, the cationic dyeable terylene / terylene / spandex fabric can simultaneously possess the anti-ultraviolet, moisture-absorbing and quick-drying and anti-crease functions with good effects.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a cationic dyeable polyester / polyester / spandex fabric dyeing and finishing process with combined functions of anti-ultraviolet, moisture absorption and quick-drying, and anti-wrinkle. Background technique [0002] With the increasing maturity of textile functional processing technology, the requirements for textile functions are also getting higher and higher. Single-functional textiles can no longer meet the needs of specific fields, and there is a broad market for composite functional textiles. [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 product...
