Foam dyeing and finishing of Shanghai Yuhui Chemical Co., Ltd.

Processing system

The system has been favored by customers because of its advantages such as energy saving and consumption reduction. The company's order task has been very full this year.

This equipment has won the innovation award of the Ministry of science and technology. At present, the famous dyeing and finishing enterprises such as mainda group, Qing Mao Group, Huafang group and Broadway group have successively applied the equipment.

Compared with traditional rolling methods, foam dyeing and finishing can reduce drying energy cost by about 50%, improve fabric processing speed by 40%, and reduce water consumption by 30%~90%.

Moreover, foam treatment can also reduce the amount of sewage, the sewage treatment cost can be reduced by 50~60%, and the consumption of chemicals can be reduced by 60~70%.

dyeing and finishing

The bottleneck of the development of the processing technology is how to apply the foam evenly to the fabric. The most important factor is the foam applicator.

Shanghai Yuhui Chemical Co., Ltd., aiming at the problems of these foam applicators, has been innovating for several years, and has launched an efficient Neovi-foam foam generator and applicator designed by its own patent.

The Neovi-foam foam finishing system has creatively solved the unstable foam produced by traditional application methods from the following aspects. It is easy to break ahead in advance, the foam stability is too high, and it is difficult to break into the interior of the fabric, causing the color difference of the fabric surface and the trouble of equipment operation and adjustment.

As the distance between the foam outlet and the width of the fabric is uniform at any point, the effect of foam attenuation is consistent, and the dyeing deviation is eliminated.

Wang Xingnan, general manager of Yu Hui Chemical Co., Ltd., told reporters that foam printing and dyeing technology had appeared in the 70s and 80s of last century, but it has not been widely used. The key reason is that the dye foam's lateral evenness is not stable, which is likely to cause uneven dyeing of fabrics.

After four or five years of research and development, Yu Hui has summed up its predecessors' failure experience and invested a lot of money and manpower and material resources to overcome the difficult problem of core technology "horizontal uniform of unstable foam".

The foam finishing system uses air instead of most of the water to carry chemicals or dyes evenly onto the surface or inside of the fabric. The main parameters such as liquid volume and chemical penetration degree can be controlled by computer, which solves the traditional defect of feeding by rolling or spraying.

At present, China's foam dyeing and finishing technology has been applied in textile finishing such as water repellent, oil repellent, hydrophilic, soft, flame-retardant, anti wrinkle, shrinkproof, antibacterial, anti ultraviolet and so on. The printing and dyeing process of denim fabric, pigment dyeing, reactive dyestuff dyeing, foam sizing, foam mercerizing, nonwovens, carpet dipping, glue coating, dyeing and other functional finishing areas have achieved ideal results.

While studying the foam dyeing and finishing equipment, Yu Hui Chemical Co., Ltd. is also exploring the foam dyeing and finishing process, and has confirmed the feasibility of foam sizing, foam printing, foam finishing and other foam processing.

Compared with the conventional rolling method, the Neovi-foam foam finishing system is more energy efficient. Compared with the circular coating and coating method, it has better fastness and handle. At present, the foam finishing system can completely replace the traditional rolling and finishing device.

Yu Hui foam finishing system has many advantages and characteristics. Its ultra low liquid feed volume can be accurately controlled by PLC between 10%~60%, and energy saving can reach over 40%.

The system can also be arranged on one side or double sides with different styles, and can be implemented in low liquid dyeing.

Foam finishing can also replace traditional coating methods to achieve a distinctive coating effect.

The foam finishing technology can be used to replace the traditional solvent type waterproof and moisture permeable coating with waterborne coating.

Practice shows that the low liquid rate foam dyeing and finishing with controllable fabric can not only greatly reduce the cost of drying energy, but also reduce the drying temperature to 65 degrees Celsius.
