New Technology Of Cotton Cold Pad Batch Dyeing Is Imperative.

On November 19th, the Great Hall of the people in Beijing was held at the National Textile Science and technology conference.

Over the past 10 years, reporters began to know Wang Limin and watched him step by step from workshop Technician, engineer, deputy director, director, deputy chief engineer, chief engineer and deputy general manager of development center.

At the beginning, when the board of directors of the China spinning and weaving Limited by Share Ltd decided that Wang Limin was the general manager of the listed company, Wang Fangshui, chief engineer of Wang Li Min's Limited by Share Ltd, told reporters: "what a pity! Such a brilliant talent is sacrificed by work."

Wang Tai's words are reasonable.

Since Wang Limin became general manager of China textile, the senior engineer who had papers and scientific research achievements has been disappearing in academic occasions every year. However, China spinning Limited by Share Ltd has gone up to a higher level in terms of technology and equipment, new technology application, product development and energy conservation and emission reduction.

Wang Limin, office of Huafang, Binzhou, Shandong.

The interview was interrupted many times, so that reporters saw Wang Limin as the general manager's busy and helpless.

But by talking with him, reporters basically understood "

"The location is different and the views are changed.

In the past, when working as a general worker, technological research was based on novelty and advancement, and now the general manager's requirements for new technology should be advanced and economic.

Wang Limin told reporters, "cold pad batch dyeing project, because of the use of room temperature cold pad dyeing, saves primer drying, washing machine steaming process and other processes, greatly saving water and electricity consumption.

After our popularization and application, the technical analysis report shows that it can save 15% of water consumption than conventional dyeing process, save 15% of electricity consumption, save more than 20% of steam, save 22% of dyeing and finishing materials, and reduce COD emissions of total effluent by 18%.

At the same time, salt is not used as a promoter, which effectively reduces the burden of sewage treatment.

According to Wang Limin, cold pad batch dyeing has been widely applied in the world for a short time, but it is mainly concentrated in developed countries such as Europe and North America.

Huafang encountered many difficulties in the study of cold pad batch dyeing process.

"Pure bring in doctrine is not feasible in the enterprise, even if the so-called mature technology, in the process of introduction, there will be a highly targeted absorption, digestion and innovation process."

Wang Limin said.

From the introduction of imported equipment, and then to optimize the selection of dyes and auxiliaries, the selection and optimization of the international published cold pad batch dyeing process parameters, spent a lot of time and effort of Huafang stock research team.

In the actual production process, they used loose mercerizing and drying to improve the final effect of the new technology.

After the application of computer technology and modern control system, they finally realized the cold pad batch dyeing process on-line tracking.

"For this technology, it is realized that dyeing process does not require steam, energy consumption is less, dye bath ratio is small, water, steam and electricity consumption is the lowest in all kinds of dyeing processes; cold pad batch reactive dyes dyeing uses less salt auxiliaries, high fixation rate, high dye utilization rate, less waste liquid emission, and the effect of energy saving and emission reduction is particularly obvious."

Wang Limin said, "in addition, the cold pad batch dyeing technology has less investment in equipment, lower capital construction costs, stronger varieties, and better dyeing effect, which can greatly improve the first rate of products."

After that, the reporter visited the series of products developed by China spinning Limited by Share Ltd using cotton cold pad batch dyeing technology.

According to the accompanying engineering and technical personnel, the fabric produced by the new technology is of moderate elasticity, fine and full handle, good drapability, smooth and clean, and has developed two kinds of products, which are high grade and medium grade. They have been pushed to the European and American markets, mainly aiming at two series of fabric purchasers of leisure and tooling. The price of new products is strong in the market and has become a new profit growth point for enterprises.

At the end of the interview, the reporter suddenly remembered two details, one of which was told by Wang Limin after he successfully quit smoking and drinking, "only good technology can make me palpitate."

One is in the academic conference of the industry, a senior expert commented on Wang Limin: "this is a guy who sees green light in the eyes of new technology."

The reporter could not help smiling.
