Not long ago, China Textile Information Center, the National Textile Products Development Center, together with China Chemical Fiber Industry Association, China National Garment Association and China Association of Home Textiles Industry, Jiangsu Xiake Green Color Textile Co., Ltd., Connaught Photoelectric Materials Co., Ltd., Enterprise Co., Ltd. and other 20 companies initiated the establishment of "China Green Dyeless Textile Innovation Alliance", "fiber liquid coloring" and other technologies because of its green and the industry has been valued. Around the current status of the technology and follow-up alliance planning, the reporter and the Union's chief person in charge of the National Textile Development Center Technical Director Chen Baojian launched from the dialogue. Improve the quality of masterbatch is a breakthrough Reporter: Please briefly introduce the development of liquid coloring technology status quo? Chen Baojian: "Stock Coloring" refers to the polyester melt (or slice) before entering the spinning box, after injection of dried, melted, filtered, measured pigment (masterbatch), together with the polyester melt High-efficient static mixer fully and evenly mixed together into the spinning box for spinning. In the melt spinning process, does not produce wastewater, is an anhydrous dyeing process. Dyeing technology is a mature liquid technology, and dyeing and finishing process complement each other. Liquid coloring process has the advantages of cleaner production, energy saving and emission reduction, but also has defects, such as high temperature resistant colorant varieties, incomplete color, add color masterbatch cause instability and other fiber production process. China from the early 70s of last century on the viscose fiber, vinylon liquid stain, nearly 10 years developed a polypropylene fiber eye liquid dyeing, from the beginning of the 1980s the introduction of spinning before the colored polyester fiber production technology, Has been widely used in industrial applications. In recent years, due to the pre-spinning coloring technology has obvious advantages in saving energy and reducing waste. In today's increasingly stringent environmental protection requirements more realistic use value, good prospects for development. Reporter: The formation of "China Green Dyeless Textile Innovation Alliance," the development of liquid coloring technology, which value the technology which can tap the potential? Chen Baojian: As the liquid coloring fiber in the fiber spinning process, by adding online masterbatch for fiber coloring, pollution-free production process, to achieve a cleaner production, the use of liquid raw fiber directly to produce finished fabric fabric, printing and dyeing directly to reduce the link, Reduce the environmental pollution caused by wastewater discharge, thus reducing the use of a large amount of energy, protecting the environment and reducing the production cost, and the color fastness of the fabric is good, including washing and rubbing fastness. Preliminary estimates, the production of plain fabric average cost savings of 5%, sports color bar fabric can save costs 19%. Such products, whether for the community, manufacturing enterprises, the use of business or consumers are very useful. Reporter: The bottleneck of the current technology where? What do you need to do if you want to make a breakthrough? Chen Baojian: High-quality masterbatch is the main bottleneck restricting the development and promotion of polyester raw liquid dyeing technology in our country. As chemical fiber production in the heat and chemical processes greatly restrict and restrict the development of masterbatch, and printing and dyeing, obviously chromatographic incomplete, not bright enough. The masterbatch consists of a colorant, a carrier, and a dispersant. The colorant can be roughly divided into dyes and pigments. The carrier has different choices depending on the type of fiber added. Therefore, breaking the bottleneck of high-quality masterbatch production should start from the following four aspects: First, the coloring agent, efforts to study high-performance dyes and pigments, especially the synthesis of high temperature dyes. The second is dispersant, through the air flow grinding and grinding technology, development and pigment size close to the dispersant. Third, the carrier, research and development of special resin to improve pigment synergies in the masterbatch and dispersion. Fourth, the establishment of high-quality masterbatch model production line to improve the mobility and dispersion of masterbatch. Upstream and downstream alliances core core strength Reporter: Can introduce the key enterprises involved in the Union, what are their advantages in this technology?
