[ Plastic Machinery Network Market Overview
] Today, sustainable development has become an important issue for the development of China's textile industry, and circular economy has become the mainstream of future development. China is a potential producer and consumer of chemical fiber in the world. The huge market demand and production scale call for cleaner and environmentally friendly manufacturing methods.
Wang Huaping, deputy dean of Donghua University Research Institute, pointed out that the sustainable development of fibers is an important attribute in the future. Recycled fibers, bio-based fibers and other fibers with green, low-carbon and recyclable characteristics, functional comfort fibers, and health protection Fibers, ultra-simulative fibers and other categories belong to the current trend and important development direction of fibers.
This requires the establishment of a green evaluation system for the entire life cycle of raw materials, manufacturing, products, and fate. Among them, green raw materials include renewable resources, bio-based resources, and biodegradable raw materials. The product green includes: easy to recycle, easy to degrade, and return to nature. Recycled fibers can improve the utilization of petrochemical resources and prevent the uncontrolled migration of non-degradable plastic products to the natural environment. Therefore, the industry should vigorously develop fiber recycling and degradable technologies.
In the future, there will only be two kinds of fibers, one is a fiber that can be recycled, and the other is a degradable fiber. One generation of materials, one generation of design. At present, designers are not simply designing styles, but integrating functions and materials into design. "Wang Huaping said.
The Huaxin Multi-Colored Colored Fibers and Recycled Functional Fibers Press Conference and China's Fiber Trends and Green Fiber Certified Product Promotion and Exchange Activities "were held in Zhejiang Huaxin New Materials Co., Ltd. (hereinafter referred to as" Huaxin ").
Green fiber refers to the chemical fiber whose raw materials are derived from biomass or recyclable materials. The production process is low-carbon and environmentally friendly. After the product is discarded, it has low pollution to the environment or can be recycled. It is an important green raw material. Huaxin's multi-color colored fiber (original colored fiber) and recycled functional fiber are green fibers.
One of the green fibers-dope colored fiber
The dope colored fiber is still a sub-industry in the chemical fiber industry in China. The annual production capacity, the richness of product specifications and models, the uniformity and stability of fiber colors, and the wide and narrow application fields are all factors. An important factor for measuring the development strength of an enterprise.
Huaxin has an annual capacity of 600,000 tons of polyester chips, colored polyester filaments, embroidery threads, and carpet threads. Among them, it has an annual capacity of 400,000 tons of colored silk, an annual capacity of 250,000 tons of chips, and an annual capacity of 10,000 tons of embroidery threads. The products are widely used in home textiles, clothing, and industrial textiles, and have developed into one of the largest domestic manufacturers of colored polyester filaments and one of the world's largest manufacturers of polyester embroidery threads.
In terms of color silk product specifications, its color silk products cover the range of 50D ~ 600D, with more than 5,000 colors and more than 46,000 products. At present, our color polyester silk color card has become one of the international standard sample cards.
According to reports, of the major scientific and technological achievements that Hua Hin passed the relevant appraisal, there are 8 items that have reached the international advanced level, including multi-functional flexible direct spinning online addition equipment and process technology research, melt direct spinning online color matching equipment and process technology research, Color mother liquor direct spinning color polyester filament technology, in situ polymerized PET
color masterbatch preparation technology, etc.
Through independent research and development, Huaxin has created a multi-color environmental protection new material innovation system model. By qualitatively identifying textile chemical fiber raw materials, replacing traditional white chemical fibers with colored chemical fibers, and replacing the post-dyeing process with dope coloring technology, the textile and chemical fiber industry is moving towards low energy consumption. , Low emissions and even 'zero' emissions, the transformation of the development direction of the low-carbon cycle has contributed its own strength. "
According to relevant calculations, compared to traditional dyeing, the production of colored fiber per ton of raw liquid can save 8300 kWh of electricity, 180 tons of water, and 130 kg of chemical dyeing auxiliary materials. If this is estimated, Huaxin has produced nearly 5 million tons of multi-color environmentally friendly new materials since it was put into production, which is roughly equivalent to a cumulative saving of 50 billion kWh of electricity, a reduction of nearly 1 billion tons of wastewater discharge, and a saving of more than 500,000 tons of chemical dyeing auxiliary materials. Both economic and social benefits are very significant.
Green fiber two-recycled fiber
Recycled chemical fiber (recycled fiber) is another major category of green fiber, which also belongs to green chemical fiber raw materials.
Huaxin deputy general manager Wang Senjun introduced that Huaxin recycles the company's colored waste yarns, uses physical and chemical methods to produce recycled chips, and spins various specifications of recycled polyester filaments; PET clothing fabrics, bottle flakes, etc. can also be used As a recycled raw material, recycled chips are produced. At the same time, Huaxin has passed the GRS system certification of chips and fibers, and established business cooperation with well-known domestic and foreign brands. Its various physical indicators and safety performance of recycled chips and recycled polyester filaments can meet customer requirements.
According to reports, Huaxin's recycling products currently include: pure white, non-ferrous recycled products, cationic recycled products, flame retardant, full extinction recycled products. The process of waste silk recycling regeneration-polymerization process is: waste silk finishing and classification, waste silk cutting, forced feeding (plus auxiliary materials), screw, coarse filter, mixing kettle, pressurization, secondary filtration, thickening, melting Body discharge, final filtration, pelletization, and production of regenerated slices. At present, the company's annual production capacity of recycled polyester chips is 35,000 tons.
The green development of the entire industry chain is the general trend
Against the background of the turbulent global green development wave, it is not only the upstream raw material industry that actively implements green development, how to make green fibers more widely used downstream, and how to better promote the greenness of the entire textile industry chain from the fiber source. Development has become a new issue that the industry needs to face.
Taking home textiles as an example, it has now formed a new position of "creative industry integrating technology and fashion". The characteristics of fashion and technology have become more and more obvious in the home textile industry, and these two characteristics depend to some extent on the use of Green materials to achieve.
Shen Shoubing, director of research and development of Shanghai Mercury 彩乐乐网 Textiles Co., Ltd. pointed out that the development of home textile products currently presents three characteristics: functional, intelligent and ecological. Among them, the ecological concept in home textile product design and material application includes many aspects. In addition to the application of natural fibers, it also includes renewable and naturally degradable fibers, recycled recycled chemical fibers, chemical fiber colored chemical fiber, and natural fiber. application.
"Green environmental protection will become a selling point for future home textile products. Brands will increasingly need to accurately understand and define customer value, to achieve a balance between social responsibility and commercial interests, and to achieve a balance between short-term interests and long-term sustainable development. "Shen Shoubing said.
