Fabric pigment dyeing and roll-drying resist-dyeing process

Abstract

The invention relates to a fabric pigment dyeing and roll-drying resist-dyeing process which comprises the following steps: respectively dipping and rolling a fabric twice on a uniform rolling vehicle by using pigment dyeing liquid, wherein the rolling waste rate is 60%-70%; then drying the fabric by infrared rays or hot air at the drying temperature of 70-80 DEG C; after drying the fabric, dipping and rolling the fabric twice again by using the same pigment dyeing liquid or different pigment dyeing liquid, wherein the rolling waste rate is 60%-70%; then drying the fabric by the infrared rays or the hot air at the drying temperature of 70-80 DEG C; and finally carrying out color fixation for 2-5 min. By using a dipping and rolling resist-dyeing process for replacing the traditional dipping and rolling dyeing process, the invention realizes deep dyeing with low-concentration dyeing liquid, and a flexible bonding agent matched with high-fastness bonding agent is applied to pure cotton and cotton / terylene blended fabrics so that the problems of poor color fastness, roller sticking, hard hand feeling of the dyed fabric and the like appearing in a pigment deep-color dyeing process of the cotton and cotton / terylene blended fabrics. By adopting the process, as the fabric does not need to be modified and washed in water after being dyed, except the condition that the preparation of dyeing liquid and the cleaning of a machine need water in a dyeing process, water is hardly needed, therefore, the problem of dyeing water consumption is fundamentally solved.

Description

technical field [0001] The invention belongs to the technical field of fabric dyeing, and in particular relates to a fabric paint dyeing, pad-drying and over-dyeing process. Background technique [0002] Low-carbon economy refers to an economic model based on low energy consumption, low pollution and low emissions. Its core is the innovation of energy technology and emission reduction technology, the innovation of industrial structure and system, and the fundamental transformation of the concept of human survival and development. Using this standard to measure various industries in my country, there is great pressure to adapt to the requirements of a low-carbon economy, especially the printing and dyeing industry. [0003] At present, 80% of the water consumption and sewage discharge of my country's textile industry come from the printing and dyeing industry, while the annual reuse rate of the discharged water from the printing and dyeing industry is less than 10%.

Problems solved by technology

In recent years, the method of dyeing light colors with paint has developed very well at home and abroad, but in the actual domestic production, there are very few people who use the process of paint dyeing to dye medium and dark colors. The main reason is that paint There are problems such as sticking rolls, poor color fastness and hard hand feeling of dyed fabrics in medium-dark dyeing

In order to improve the dyeing depth of paint, some people have studied the cationic modification dyeing process of cotton fabrics, but after modification or dyeing, water washing is required, which cannot fundamentally solve the problem of large water consumption, and cotton fabrics are likely to cause color differences after modification.

In addition, cationic modifiers also have a certain impact on the biochemical treatment of printing and dyeing wastewater
