Embodiment 1

[0027] The YLD high-temperature and high-pressure air-flow atomization dyeing machine produced by Wuxi Yilida Chemical Printing and Dyeing Machinery Co., Ltd. is used.

[0028] The printing and dyeing process includes the following steps:

[0029] 1) Pre-treatment: put the cotton fabric in a singeing processor for singeing treatment, the conditions for singeing are: vehicle speed 80±2m / min, wind pressure 10±1mbar, burner through burning, gas pressure 0.11 ±0.01MPa, drying steam pressure is 0.1±0.05MPa, fire extinguishing steam box pressure is 0.02±0.01MPa, rolling car pressure is 0.3±0.05MPa, tension frame pressure is 0.4±0.1MPa, so that the obtained fabric singeing level 4 or more. Afterwards, the fabric is subjected to enzymatic desizing treatment, scouring and bleaching treatment. The working solution of enzymatic desizing treatment is penetrant JFC (Shangyu Chuangyu Chemical Co., Ltd.) and desizing enzyme TF-162D (Transfar Co., Ltd.) aqueous solution. The concentration o...

Embodiment 2

[0033]Basically the same as Example 1, the difference is that in step 3) of this example, before pre-baking, the dyed fabric is first immersed in a silane coupling agent-modified nano-silica deepening agent, dipped into Roll for 5min. The preparation method of the silane coupling agent-modified nano-silica deepening agent comprises the following steps: first dissolving nano-silica with an average particle diameter of 20nm (with a particle diameter range of 10-30nm) in ethanol to obtain nano-silica The weight percentage of silicon is 2.5% nano-silica ethanol dispersion, then add vinyltriethoxysilane (A-151) to the nano-silica ethanol dispersion, the added A-151 and nano-silica The mass ratio of nano-silica in the silicone alcohol dispersion is 10:100, react at 25°C for 24 hours, and obtain a silane coupling agent-modified nano-silica solution. The silane coupling agent-modified nano-silica solution is mixed with water at a mass ratio of 1:40 to obtain a silane-coupling agent-m...

Embodiment 3

[0035] Basically the same as Example 2, the difference is that in step 3) of the present embodiment, before padding in the nano-silica deepening agent modified by silane coupling agent, padding in aqueous solution of crosslinking agent for 5min, crosslinking The aqueous linking agent solution contains 100g / L of crosslinking agent JF-694A (Wujiang Jinfeng Chemical Co., Ltd.) and 50g / L of softener JF-2010 (Jiashan Jiangnan Textile Material Co., Ltd.).

Abstract

The invention discloses a printing and dyeing process which comprises the following steps: (1) preprocessing; (2) dyeing, namely putting a preprocessed fabric into a dyeing solution, heating the dyeing solution to 45-55 DEG C at speed of 1-2 DEG C/min, and keeping the temperature for 20-40 minutes; adding sodium chloride, heating to 60-70 DEG C at the speed of 1-2 DEG C/min, and keeping the temperature for 20-40 minutes; adding sodium carbonate, heating to 80-90 DEG C at speed of 0.2-1 DEG C/min, and keeping the temperature for 20-40 minutes; finally cooling at the speed of 1-2 DEG C/min to finish the dyeing process; (3) post-processing. According to the printing and dyeing process, the dye-uptake rate and the dye-uptake process are adjusted to be optimal through controlling temperature ranges in the dyeing process, so that a printed and dyed product is good in dyeing uniformity and high in color fastness. The printing and dyeing process is simple, can realize large-scale industrialization production and bring good economic benefits to enterprises, and has a wide prospect.

Description

technical field [0001] The invention relates to the field of fabric printing and dyeing, and mainly relates to a printing and dyeing process. Background technique [0002] The textile industry is a traditional pillar industry in my country, including five parts: textile, printing and dyeing, chemical fiber, clothing and textile special equipment manufacturing. With the rapid development of the national economy, my country's printing and dyeing industry has also entered a period of rapid development, the level of equipment and technology has been significantly improved, and the production process and equipment have been continuously updated. The printing and dyeing process refers to the general term for the physical and chemical treatment of various textile materials (yarns, fabrics) during the production process, including the pretreatment, dyeing, printing and finishing processes of textile materials, collectively referred to as the printing and dyeing process. Dyeing is a...
