At the conference, the results of the 2011 environmental friendly sizing active promoters were also announced. The outstanding promoters of 2011 environmental protection sizing were Xiao Wei, general manager of Jingjiang Yufu Textile Co., Ltd. of Jiangsu Yu Lun Textile Group, and Luoyang Baima Group, an active promoter of 2011 environmental protection sizing. Wang Hongtao, deputy general manager of the responsible company, Zhao Zhihua, assistant to general manager of Jiangsu Dasheng Group Co., Ltd., and Wu Qinxia, ​​deputy general manager of Henan Xinye Textile Co., Ltd., gave commendations.
Textile sizing is one of the key processes for reducing consumption and reducing emissions in the cotton textile industry chain. Due to the poor biodegradability of PVA slurries and the difficulty of disposal of desizing waste liquids, it will cause environmental pollution. Therefore, as early as in 1997, the China Cotton Textile Industry Association proposed the use of sizing for the first time at the pulp and sizing technology annual meeting. Do not use PVA's strategic goals. After more than ten years of unremitting efforts, the implementation of PVA-free sizing has become a consensus. Today, under the new situation of energy-saving and emission-reduction, it is of great practical significance to further promote “green sizing†on the basis of “no PVA sizingâ€. The so-called "environmental sizing" on the one hand is that the sizing must use environmentally friendly sizing, and on the other hand sizing must also be environmentally friendly and low-carbon. At the annual meeting, the delegates specifically discussed the definition and testing of environmental protection slurry, and promoted the promotion of environmental protection sizing.
At the annual meeting, Zhu Beina, president of the China Cotton Textile Industry Association, focused on analyzing the status of textile sizing and the direction of cleaner production. In 2011, due to the weakening of the market, the situation of high-priced inventory and low-priced products was serious, and some small-scale weaving enterprises had the phenomenon of stop production and parking. However, overall, the proportion of shuttleless looms and shuttleless fabrics in the weaving industry has continued to increase, and new product categories have increased. During the “Eleventh Five-Year Plan†period, through the adoption of new technologies, new processes, and improving the comprehensive utilization of various energy sources, energy saving, emission reduction, and energy-saving and consumption-reducing effects are more obvious. With the improvement of yarn quality and equipment level, the improvement of the sizing technology level, the continuous availability of new slurry materials, and the growing awareness of corporate environmental protection, the proportion of PVA slurry applications has gradually decreased. However, weaving mills simply seek to reduce the cost of pulp and seek to improve the efficiency of weaving machines. Printing and dyeing factories only pay attention to the cost of raw materials for purchasing grey fabrics, and do not attach importance to the cost of sewage treatment, resulting in non-degradable pulp still occupying the market. She proposed that the implementation of cleaner production is mainly to implement product green design, implementation of the entire production process control, and implementation of material optimization management. The specific requirements for clean production in the sizing process are the use of environmentally friendly slurries, and it is imperative to keep away from PVA and other non-environmentally friendly slurries. She said that in the future, the association will vigorously promote environmental protection sizing work, strive for the government's policy support for clean production, do a good job in the promotion and publicity of environmental protection sizing, and continue to carry out the annual environmental sizing active promoters selection activities. Through the joint efforts of the entire industry, we will actively research new raw materials and new processes, implement clean production, reduce the amount of pollutants generated and emissions, and achieve sustainable development of the industry.
Gao Weidong, vice president of Jiangnan University and director of the Textile Sizing Professional Committee, proposed in his work report that the promotion of environmental protection sizing has come to the forefront. There is still a long way to go to achieve a PVA-free sizing because of the gap between the new type of slurry and the PVA slurry in some aspects. At the same time, the research and practice of energy-saving and environmental-friendly sizing process should be paid attention to.
According to Wan Guojiang, chairman of Shanghai Qi Li Auxiliary Co., Ltd., environmental protection green sizing is a systematic project that is related to yarn, slurry properties, sizing process, and looms type. At present, PVA slurry is still used in large quantities, and there is a lot of room for innovation in acrylic slurry and starch slurry. For the phenomenon that the current industry contains PVA slurry as an environmental protection slurry, he believes that inspection monitoring should be strengthened to combat illegal activities. Through the establishment of a product identification system based on infrared spectroscopy, a scientific feature index test method was established, and monitoring work was conducted through a reputable intermediary agency.
Shandong Demian Co., Ltd. Li Xinshun said that how to use no or less PVA, but does not affect the yarn weavability, does not affect the cloth machine efficiency and cloth quality, this is a systematic problem, only from the slurry company research It is not enough to replace PVA's environmental protection slurry. It is also necessary to start with raw materials, yarn quality, production equipment, and production processes. The use of an environmentally friendly slurry with the same sizing performance as PVA adhesion is an effective way to realize environmental protection sizing.
Around the sizing process, the application of new types of slurry, slurry testing and evaluation, the relevant experts and companies conducted in-depth discussions and exchanges.
Wang Yuqi, secretary-general of the China Cotton Textile Industry Association, stressed in the summary of the conference that it is necessary to increase research and exploration for the production technology that does not use PVA's environmental protection sizing, to get rid of the shackles of the original PVA sizing conservative process, and to boldly innovate and practice energy-saving, environmental-friendly sizing Technology, new process.
This annual meeting is sponsored by the China Cotton Textile Industry Association, and organized by the Textile Sizing Professional Committee, and co-organized by Shanghai Qili Additives Co., Ltd. Zhang Shiping, deputy director of the Ministry of Industry of the China Textile Industry Association, Han Ping, vice president of the Jiangsu Textile Industry Association, and former president of the China Textile University Zhou Yongyuan attended the annual meeting.
How to ensure the sizing quality without using PVA slurry and how can we achieve environmentally friendly sizing? From July 7th to 8th, at the “National Slurry and Sizing Technology 2011 Conference†held in Wuxi, the promotion of environmental protection sizing became the focus of the conference’s representatives. More than 240 textile and pulp industry representatives from across the country attended the conference. The conference focused on the theme of "innovative technology, environmental protection sizing" and conducted discussions in three forms: special report, group discussion, and annual forum.
