Problems solved by technology

Vacuum dye sublimation dyeing has problems such as small number of sublimation dyes, difficulty in controlling sublimation speed, serious equipment pollution, and high requirements for dyeing equipment, which greatly limit its popularization and application in the textile industry.
Therefore, a better technology is still waiting to solve the above-mentioned problems in the field of non-polluting textile dyeing.

Embodiment Construction

[0015] The specific process of anhydrous dyeing of polyester fabric with disperse dyes is as follows:

[0016] (1) Preparation of disperse dye coating materials:

[0017] Put the powdered pure disperse dye (Jiangsu Yabang: Disperse Red FB) into a constant temperature oven (BINDER FD 53 300C), and choose 50 ℃ to dry for 20 minutes to remove excess water in the dye.

[0018] (2) Use conventional dyeing pretreatment processes, such as desizing, bleaching, and degreasing, to pre-treat the textile to be dyed. This step is a conventional operation technique in the field, and the requirements to be met by the pretreatment are also normal specifications, so I will not repeat it here.

[0019] (3) Plating of polyester fabric:

[0020] Select 15cm×15cm size degreasing warp knitted polyester white cloth (100% PET, DTY, 50D / 72F, 100g / m 2 ), put the dried disperse dye into the high vacuum resistance evaporation coating machine (Beijing Techno Technology Co., Ltd., ZHD-300M2). Start the coating mac...

Abstract

The invention relates to a water-free dyeing technology for textiles. The method comprises the following steps: taking a textile fabric as a substrate, taking pure dyes as a coating material, depositing the dyes onto the surface of the textile fabric by utilizing physical vapor deposition, and performing fixation on the coated fabric in after-treatment manners such as ageing, heat setting and the like. According to the scheme of the invention, uniform and dense dyes are deposited on the textile surface through the physical vapor deposition technology, the textile dyeing aim is achieved through after-treatment and fixation, the process is simple and convenient, wastewater emission in the whole production process is avoided, the dye utilization ratio is high, the operability is high, and batch production is easily realized.

Description

Technical field [0001] The present invention relates to the technical field of textile printing and dyeing and physical vapor deposition, and more specifically, to a water-free dyeing method for textiles. Background technique [0002] Traditional textile dyeing technology uses water as a carrier and combines dyes with textiles through the action of warming and auxiliary agents to achieve the purpose of textile dyeing. The dyes on the textiles and the dyes in the carrier water maintain a dynamic balance. After the dyeing, a large amount of dyes will remain in the dyeing residue. At the same time, various additives added during dyeing will be partially retained in the dyeing residue; due to the current wastewater The cost of treatment technology is relatively high, and it cannot completely solve the problem of printing and dyeing wastewater. Therefore, the discharge of printing and dyeing wastewater has always been a key and difficult problem for energy saving and emission reductio...
