Polyester-cotton fabric is of the most popular one of the textile fabrics, with cotton as two-component, taking into account the advantages of two kinds of fiber, has low price, good moisture absorption, Preserving advantaged. However, with different composition, the dyeing process is more complicated, the traditional dyeing process must include the components of pre-treatment of cotton, polyester dyed, cotton dyeing three processes, not only time consuming, and high energy consumption, low efficiency, quality control process points more difficult to control product quality. >> Textile energy saving in action

Justice Wujiadelai Co. SR by new materials used in the processing of polyester fabric, polyester cotton innovative energy efficient refining a kind of dye bath with the new process, shortening the process to achieve energy saving and emission reduction, improve processing efficiency and quality.

Production To cotton knitted fabrics, for example, by SR, glacial acetic acid, high-temperature leveling agent BOF, no foam soap lotion, free fixing agent dispersed dark blue, the temperature reactive dyes and other agents, the light process: SR 40 30min HAC0.5g / L, Disperse x%, BOF operation temperature to 130 10min insulation 40min cooling dyed cotton, reduction cleaning fixing soft soaping stereotypes dehydration drying.

New Technology SR staining the finished product specifications
The SR product new technology with traditional craft dyeing process of the same size fabric at the same time, and the results are as follows:

Color similar to the traditional craft 3.5 level;
Fixation with the traditional process very reactive 70% (according to the type of dye may be);

Washing fastness with the traditional process rather 3 level;
Rubbing fastness with the traditional process rather 2.5 level;
Light fastness with the traditional process rather 3 level;
23 kinds of non-carcinogenic aromatic amines;
Formaldehyde 25ppm; PH value = 4.5 ~ 7.5;
Shrinkage warp, weft 4.5% SR New Technology and Traditional Craft more
Traditional cotton dyeing comparison, SR new process has the following features.
1) the use of free formaldehyde, APEO, easily biodegradable, environmentally friendly raw materials, synthesized by polymerization of new printing and dyeing treatment agents SR, not only environmental, but also has high temperature, electrolyte resistance, wide range of pH values stability characteristics fully meet the dyeing process requirements to ensure consistent quality products, the use of different batches of the same effect. As the processing technology to avoid the traditional base for the use of pre-treatment, the complete elimination of the fabric base cook-for water to wash thoroughly, not the obviousness base cloth to produce alkali spot so hard to fix the flaw; to ensure the stability and repeat process sex.

2) the use of existing plant equipment, rely on effective environmental support for printing new material SR will load in the pre-treatment process after the completion of the dyeing processes, saving pre-treatment process and shorten the baking process, saving time and reducing employment, improve productivity, reduce energy consumption, reduce waste water discharge, reduce production costs for efficient processing of short process, to reduce energy consumption.

3) a decrease of additive type, streamline procurement strength, reduce the storage burden, reduce labor intensity and labor employment, while reducing the large number of pre-treatment agent added to reduce treatment load.

4) This process streamlined operational processes, simple operation, the variable will affect the staining quality factor greatly reduced.

New Technology SR processing costs compared with traditional technology
Production practice proves that the SR can achieve energy saving and reducing consumption of new technology, cleaner production objectives. The actual situation of enterprises in accordance with practice, comparing the old and new technology, equivalent to the processing costs of each treatment 1t material changes as follows:

1) water conservation 50t (liquor ratio 1:10), in accordance with the water price 5 yuan / t basis, can save 250 yuan;

2) to reduce sewage discharge 50t, in accordance with the Sewage Treatment 2 yuan / t basis, can save 100 yuan;

3) save processing time 120min; 4) energy saving 90 degrees, according to the average price was 0.68 yuan / calculation, saving 61.2 yuan;

5) saving steam 2.5t, in accordance with the steam unit 130 yuan / t basis, can save 325 yuan;

6) pretreatment auxiliaries saving cost: 325 yuan;
7) to reduce labor wages: 55 yuan.
SR environmentally efficient new technology as a significant energy saving potential of new technology, it is worth to promote the industry. Dyeing fabric according to the national annual output of 500,000 tons, he may save 25 million tons of fresh water resources, reduce waste water discharge 25 million tons, saving 1.25 million tons of steam, electricity saving 45 million kilowatts, to reduce amount of one million tons of caustic soda, 25% production efficiency , an integrated direct costs per ton of material can reduce the 1116.2 yuan, the annual cost 560 million yuan. This technology can bring the entire printing industry of China’s multi-component fibers, fabrics and cut energy consumption and efficient cleaning, dyeing and finishing, has great market potential and promote the value and the significant economic and social environmental benefits.
