According to market demand, starting from raw material selection, degumming process application, high grade linen production, carding and blending process determination, blending raw material ratio determination, main equipment selection and so on, through the technical tackling of one by one, we successfully developed 72 public branch pure hemp yarn, 50 common ramie viscose yarn and 58 public branch hemp yarn, which can reach 100 public grade high grade pure hemp fabric standard. In addition, through many years of hard exploration, Yuzhu successfully developed its own "silk spinning + wool spinning" combing process. At present, the 04 and 05 hemp strips produced by the Polygonum industry have better overcome the prickle sensation of ramie fabric.

In recent years, the pace of technological transformation of the textile industry has been accelerating, and the investment in advanced technology and equipment has been increasing. Through the upgrading of domestic equipment manufacturing technology and the introduction of foreign advanced technology and equipment, the overall equipment and technology level of the industry has greatly improved. At present, the proportion of linen textile and international advanced equipment has reached over 60%, and the percentage of non spinning head yarn has reached 70% and the shuttle free rate of linen spinning has reached more than 60%. The overall upgrading of the technical level of the hemp spinning equipment has provided a good job for the economic operation and efficiency of the whole industry. Market opportunity And development platform.

Environmental protection is an inevitable trend.

The promotion and application of a series of independent innovative new processes, new products and new technologies, including refined hemp fiber processing, wet spinning, flax coarse yarn yarn project, hemp degumming, and 300 pure ramie fabrics, have effectively increased the added value of linen textile products, expanded exports, enhanced the competitiveness of the international market, and played a positive role in promoting the upgrading of the hemp textile industry.

Changzhou Meiyuan Flax Textile Co., Ltd. has adopted the technology of oxygen bleaching and enzyme treatment instead of the traditional "sub oxygen bleaching" process. It has solved the problem that most enterprises use the chlorine bleaching agent to degum and bleach linen roving to pollute the environment, shorten the technological process and reduce energy consumption. It is estimated that it can save electricity by 450 thousand degrees, save 1750 tons of steam, and save 45 thousand tons, which is equivalent to 288.3 tons of standard coal. The sewage reaches the national three level discharge standard and enters the urban pipe network.

Chongqing Fuling Jindi Industrial Group Co., Ltd. adopts the self-developed JD-1 type ramie degumming assistant for quick degumming, and achieves the purpose of Fast Degumming. The JD-1 drafting machine, which is developed independently, is used instead of the hemp machine to reduce the labor intensity and the degumming uniformity of the workers. By adopting the newly developed new bleaching acid washing oil combined machine technology instead of the old bleaching acid pickling and oil feeding process, it can save 720 thousand tons of water each year, save electricity by 360 thousand degrees, save steam 33000 tons, and replace less than 4650 tons of standard coal.

Technical bottleneck needs breakthrough

The "outline of scientific and technological progress" of the textile industry in 12th Five-Year clearly pointed out that during the "12th Five-Year" period, the key technology to break through in the hemp industry is "advanced, efficient, low consumption and environmental friendly spinning technology and equipment for hemp fibers", mainly in the development of Ramie and leanable flax and stretch cutting technology and equipment.

Dong Chunxing, vice president and Secretary General of China's Textile Industry Association, explained that because of the small scale of the linen textile industry, the development of equipment has long been restricted. In particular, ramie equipment has been in a backward state for a long time. There is no large spinning machine enterprise to focus on development. Basically, it is a transformation of the spinning and weaving enterprises in the cotton spinning, wool spinning and silk spinning equipment, and there is a lack of stereotyped equipment for a long time. Dong Chunxing hoped that domestic textile machinery enterprises could increase their attention to the development and transformation of ramie complete equipment. It is understood that at present, Zhengzhou textile machinery Limited by Share Ltd is striving to make breakthroughs in Ramie equipment.

The length of hemp fiber is longer. In order to facilitate the blending of cotton and other fibers, it is necessary to cut the hemp fibers into a certain length by stretch spinning, so that the cotton spinning equipment can be used for production. Dong Chunxing said that experts from Donghua University had already conducted corresponding research with the enterprises, but there is no stereotyped product at present. It is hoped that the technology optimization and process equipment will be finalized during the "12th Five-Year" period and will be promoted in the industry.

The pollution caused by degumming has always been a major problem restricting the development of the industry. Most enterprises adopt chemical degumming, especially ramie degumming. Dong Chunxing said that the use of biological or biological enzyme technology for degumming in some enterprises has begun to apply, some of the good results, some of the effect is generally, basically still in the pilot or pilot stage, production stability needs to be improved, there is no large-scale promotion and application.

The hemp spinning industry is a typical labor-intensive industry, and the employment of 300~500 million people is much higher than that of other textile industries. This is a prominent contradiction that the industry needs to solve today. Ramie reduction, degumming and rapid degumming are aimed at reducing labor and reducing labor intensity. In addition, as the process shortens, it saves water and electricity, improves efficiency and reduces pollution emissions.

Dong Chunxing believes that as long as the technology of degumming is passed and mature, the equipment can reduce employment and reduce pollution emissions, and enterprises will actively apply it. He hoped that during the "12th Five-Year" period, 10000 yuan employment could reduce 100~200 people on the original basis.
