    With the introduction of the new emission standards of the national printing and dyeing industry, the upgrading and upgrading of the printing and dyeing enterprises sewage treatment plants have been put on the agenda. At present, the concentration of desizing and boiling wastewater is the highest among all kinds of wastewater discharged from the printing and dyeing industry, and the desizing wastewater is the key and difficult point of printing and dyeing wastewater treatment because of the large amount of PVA composition of chemical slurry.


    In order to ensure printing and dyeing According to the principle of sewage diversion and source treatment, the success of the pretreatment technology of desizing wastewater has become the restrictive factor and bottleneck for the treatment effect of the whole system.


    So far, there is no engineering case or technical experience for reducing PVA composition of wastewater at home and abroad. It can be seen that the treatment technology of wastewater containing a large number of PVA components is facing great challenges and opportunities.


    Beijing Huaxia Dayu Technology Co., Ltd. has maintained a high degree of concern for printing and dyeing wastewater treatment technology. Since August 2013, the company has designed and developed a set of treatment processes according to the characteristics of the waste water, and has carried out pilot plant experiments on printing and dyeing wastewater for two months at a printing and dyeing enterprise in Shandong, and made breakthroughs.


    The process adopts " DYAR Anaerobic technology +DYOF- aerobic reactor technology, in order to reduce the PVA, pectin and other high molecular pollutants as the core target, with the characteristics of high degradation efficiency, good effluent quality, low operation cost, simple operation and less sludge volume, the removal rate of PVA is above 70%, which is significantly ahead of the average level of the same industry.


    The success of the experiment was filled. Printing and dyeing wastewater The blank of PVA treatment technology provides valuable technical experience and successful case for the treatment engineering of desizing wastewater and printing and dyeing wastewater. It will also promote the extensive application of new technology for the promotion of printing and dyeing industry batik wastewater treatment, and provide strong technical support for the implementation of clean production and pollutant emission reduction in printing and dyeing enterprises.

    The application of functional fiber to home textile industry is an important step in the transformation of home textile enterprises to science and technology. However, as far as price is concerned, it has to form a natural barrier to a certain extent, which hinders the popularization and development of functional home textiles in the terminal.


    Against this background, after the release of three functional products such as Luca, saaras, and onet in 2012, the domestic functional fiber independent R & D agency, blue products technology, released three new products such as Mu Sen, Xian Shu, Visca and so on at the end of 2013. These three new products have continued the advantages of the blue products company in terms of product functionality, but the biggest highlight is the price setting. After studying, the blue goods technology decided to keep the three functional new products and the conventional products near the price, so that they could help the home textile brand enterprises at a lower price, so that the price advantage could be reflected in the terminal, and finally the popularization of functional home textile products in the terminal would be promoted.


    Mu Sen, Xian Shu and Visca three new products choose modified recycled materials as raw materials, and their environmental performance is outstanding. Compared with ordinary fibers, Mosen fiber has higher strength and elongation at break, and its surface is smooth, which can effectively reduce the friction coefficient. It is a product that gives people a sense of lightness and lightness. The fiber has good softness and moisture conductivity, which can make the skin in a dry atmosphere at all times. The fluffiness and resilience of Weiss card fiber are obviously better than that of ordinary fibers. The finished products made of it are smooth, uniform, softly colored and breathable, which is an excellent choice for high quality sleepers.
