High Speed And Efficient Wet Cloth Mercerizing Process

Dry cloth mercerized and wet cloth mercerization from the dry and wet of the fabric.

Because of the surface mercerization of wet cloth mercerizing, it can not penetrate the core mercerizing and the problem of uneven mercerization.

The reason is that the moisture content of the wet fabric is uneven, and the strong alkali can not penetrate completely and permeate inhomogeneity.

To solve the problem of wet mercerizing, the equipment should focus on solving the problem of the lowest and even consistency of the wet cloth before the alkali concentration.

After wet cloth is inserted, the design of immersion tank and high efficiency re rolling is the key to achieving wet mercerization.

In the leaching tank, the test of light alkali and strong alkali was carried out. Only when the weight of alkali was increased, the value of mercerized barium was the best, and the impregnation tank was divided into layers and gradually impregnated with concentrated alkali. The main condition of wet mercerizing was also improved. The range of pressure adjustment was increased. The smaller the rolling rate, the better the best. The medium and solid roll was used to improve the deflection of the roll, and the uniformity of the rolling ratio between the front and the left was strictly controlled.

Other equipment tackled key problems before the same process.

The technology mainly solves the problem of soaking wet cloth and strong alkali.

The formulation and adjustment of technological parameters are caustic soda concentration - gram rise, penetration agent dosage, and caustic soda temperature, and the production speed is 8 meters.

Mercerizing semi-finished products test: barium value is - - indicating mercerizing.

Attention should be paid to the following problems: in actual production, it is necessary to regularly check the rolling rate and uniformity of the rolling stock before the alkali concentration, and the consistency of the strong alkali. The best combination of driving and bleaching and mercerizing is the best. If the wet cloth is stored before mercerizing, it will cause partial air drying, resulting in uneven evenness.

Analysis of social and economic benefits.

The one-step method is compared with the two step method: the equipment occupies less space and saves land.

The machine is completed from singeing to boiling and bleaching at once, shortening production and delivery time, and achieving short and quick delivery in small batch production.

High speed and high efficiency, increase the speed of the car from rice to 8 meters, improve production efficiency and reduce cost.

Sewage discharge per ton / day falls to tonnes, sewage treatment costs are reduced by half and sewage discharge is reduced by half.

Compared with the wet cloth mercerizing: the three column drying machine is saved, the steam consumption is obvious, and the steam consumption is saved by about ton per day.

After drying and bleaching, it does not dry, and the wash and wash rinse will not be washed away. It will continue to wash away when it is mercerized. It will make up for the insufficient washing. In the process design of the combined machine, it can reduce the design of washing capacity.

If it is dried, it will not expand when it is mercerized. It is not easy to wash away, resulting in poor printing and dyed dyeing and dyed dyes.

The fiber puffing foot is uniform in alkali leaching, uniform in product quality, good in dyeing, high in cloth quality, and high in product qualification rate.

Wet cloth and mercerizing do not produce broken edges.

Wet cloth and mercerizing fall wide.

High speed and high efficiency, because of wet cloth mercerizing through core processing, can improve vehicle speed and improve production efficiency, and reduce the cost of dry cloth mercerizing by about the traditional technology.

The machine is from the singeing, boiling, bleaching and mercerizing, and combined with one process to reduce the intermediate links. The production cycle is short, the efficiency is high, the product quality is high, and it is very suitable for the current cleaner production requirements.

The application of the above technology accords with the policy of circular economy of energy conservation and emission reduction, and has wide social and economic benefits.

The annual production volume of every 10000 production lines per customer can save about 10000 yuan per year because of saving steam, electricity and water. The company can save nearly L8 million yuan annually by sharing the bar production line, bringing huge economic benefits to customers and greatly improving the market competitiveness.

By the Provincial Textile Association of China as the 8 year energy saving and emission reduction excellent enterprise.
