Green fiber is increasingly becoming the "darling" of the fiber industry.
On the evening of March 16th, “Shenghong·China Fiber Trends 2016/2017 Conferenceâ€, China Chemical Fiber Industry Association held the “Green Fiber†LOGO, and invited 10 public stars to participate in the opening ceremony. Awarded the first eight companies to receive “green fiber†certification. In the "China Fiber Exhibition Area" of this year's Yarn Show (Spring and Summer), a special "Green Life Theme Exhibition Area" is also set up, including "Recycled Fiber Exhibition Area" and "Bio-Based Fiber Exhibition Area".
Green fiber refers to the raw material derived from biomass and recyclable materials. The production process is low-carbon and environmentally friendly . It is chemical fiber that is environmentally friendly after being discarded. It mainly includes bio-based chemical fiber, recycled chemical fiber, and liquid coloring chemistry. Fiber, etc.
In response to the implementation of the green development concept, the company promoted “green manufacturing†in the whole industry. Since 2013, the China Chemical Fiber Industry Association has begun to launch the “Green Fiber Projectâ€. In 2014, China Chemical Fiber Industry Association applied for the “Green Fiber†certification mark to the State Administration for Industry and Commerce. It was announced on April 20, 2015, and the “Green Fiber†trademark was approved on June 20, 2015.
After approval, the “Green Fiber†logo became the certification mark for the materials of the above three types of green fiber products. After applying, reviewing, inspecting and approving, the enterprise can obtain the right to use the “green fiber†mark and accept the supervision and management of the trademark use process by the China Chemical Fiber Industry Association.
Duan Xiaoping, president of China Chemical Fiber Industry Association, said that through the establishment of the "green fiber" certification system and project promotion, the green certification system for fiber materials will be improved to guide the green development of the industry. While helping products improve technical safety, we advocate green design, green materials and green manufacturing of products, promote environmental protection and public health, and achieve the long-term goal of corporate development and social responsibility.
Duan Xiaoping said that the green fiber certification system includes raw and auxiliary materials procurement, production process, other management systems, fiber product quality and end product quality. The “green fiber†logo can be applied to fibers, yarns, fabrics, garments, home textiles, industrial textiles and other fields.
“The 'green fiber' certification is a very rigorous thing. First, the raw materials and auxiliary materials purchased by the company cannot contain toxic chemicals; secondly, the production process must comply with the national environmental emission and clean production standards; meanwhile, the final product pairs produced The environment and the human body are both friendly and non-toxic. Only when all the links are up to standard can the relevant certification be passed.†Duan Xiaoping emphasized this.
Regarding the long-term significance of implementing the "green fiber" project, Duan Xiaoping said: "Green development, as one of the five development concepts put forward by the Fifth Plenary Session of the 18th Central Committee of China, has become China's new industrialization road, adjustment and optimization of economic structure, and transformation of economic development. The important driving force of the way. As the source of the development of the textile industry chain, fiber's green development process is of great significance to promote the sustainable development of the textile industry and the whole society."
Bio-based fiber: a combination of environmental protection, green and high performance
In this year's Yarn Show (Spring and Summer), there are 9 companies participating in the Bio-Based Fiber Exhibition, including Qingdao Baicao, Shaoxing Jiuzhou, Kaisai Bio, Tangshan Sanyou Group Xingda Chemical Fiber, Nantong Jiuding, Shanghai Quanyu, Henan Longdu Biotechnology, Qingdao Kangtong Marine Fiber and Shanghai Tianzhu Textile Fiber.
Bio-based fiber is a kind of renewable fiber processed from agricultural, forestry, marine waste and by-products. The application of bio-based fibers not only reduces the dependence on petroleum resources, but also effectively combines resource sustainability with scale of production to achieve “three substitutions†(raw material substitution, process substitution, product substitution) and “three combinationsâ€. "Combined with the biochemical industry, combined with energy conservation and environmental protection and waste utilization, combined with functional improvement and application expansion."
Bio-based fibers have great potential for development. First of all, bio-based fiber products have a wide range of properties for conventional chemical fibers, and can be applied to many fields such as textiles, medical materials, health protection, and aerospace military. Secondly, bio-based fibers and their raw materials are recyclable and biodegradable, environmentally friendly, and in line with current and future green environmental trends.
At the same time, bio-based fibers have properties that go beyond conventional fibers. At present, China's bio-based fibers mainly include bio-based new cellulose fibers, bio-based synthetic fibers, and marine bio-based fibers. Bio-based new cellulose fibers are made from conifers, wood scraps, etc., such as Lyocell fibers; bio-based synthetic fibers are produced by fermentation of agricultural and forestry by-products, such as PLA fibers, PTT fibers, etc.; The base fiber is prepared from aquatic products such as algae, shrimp, crab, and the outer shell of arthropods such as insects, such as alginate fibers and chitosan fibers.
Among them, PLA filament and staple fiber have good biodegradability and environmental protection properties, as well as good thermal insulation, bacteriostatic, skin-friendly, moisture wicking, flame retardant and UV resistance. PTT fiber combines the softness of nylon , the bulkiness of acrylic fiber, the anti-staining property of polyester , and the elastic recovery ability close to spandex . It combines the excellent properties of various chemical fibers and is the latest hot polymer developed in the international market. One of the materials.
Recycling Fiber: Making Waste “Newâ€
At this year's Yarn Show (Spring and Summer), there are 9 recycling and recycling enterprises participating in the Recycled Fiber Exhibition, including Longfu Huaneng, Youcai Environmental Protection, Haiyan Haili, Hangzhou Advanced Fuchun, Hangzhou Benma, Shandong Gran Germany, Ningbo Dafa, Zhangjiagang Anshun Technology and Hangzhou Huaerli.
Recycled fiber is a fiber made from waste bottle, plastic and waste textiles by chemical or physical means combined with spinning technology. This fiber can continue to be used in various fields such as textiles and materials. For example, waste textiles can be used for weaving gasket materials, covering materials, filter materials, building materials, decorative materials, etc. after being crushed, opened, spunlaced or spunbonded into a web, and deeply molded.
According to statistics, the annual global waste textiles exceed 40 million tons, China accounts for 1/2; the world's waste plastics recycling volume is nearly 200 million tons, and China accounts for 1/5. The comprehensive utilization of these wastes can greatly change the structure of our raw materials and the structure of energy consumption. If we recycle 3000 pieces of T-shirts (about 1 ton) with recycled polyester fiber and original polyester fiber, the recycling process can reduce CO2 emissions by 52% compared with the original products, saving 39%. Energy consumption has good ecological and economic benefits.
During the “Twelfth Five-Year Plan†period, China's recycling and utilization of fiber production capacity and output increased rapidly with an annual growth rate of more than 10%. At present, small batches, multiple varieties, high quality and differentiation have become the mainstream of recycling products. The products cover filament, cotton, wool, filling and non-woven products, mainly used in clothing, home textiles and industrial use. Large class of terminal areas.
Today, when the shortage of resources is further aggravated and environmental pressures are further increased, recycling of fiber is an important practitioner of implementing the national circular economy and building a resource-based society. It is in line with the development model of low-carbon economy and the national strategy for sustainable development.
Raw liquid coloring fiber: both ecological value and economic benefit
At this year's yarn show, a number of companies have demonstrated raw liquid coloring fiber products, such as Fujian Jinxia. During the "Twelfth Five-Year Plan" period, China's raw liquid coloring fibers developed rapidly. In 2014, the output of China's raw liquid coloring fiber was about 4.5 million tons, accounting for 10% of the total chemical fiber production in China. At present, China has formed a relatively complete industrial chain of pigmented fibers.
The raw liquid colored fiber refers to a colored fiber obtained by adding a coloring agent before spinning by a pre-spinning dyeing technique. Since the traditional dyeing and finishing process is omitted, the production of the raw liquid colored fiber can save water and reduce emissions, and meet the requirements of "low carbon". Statistics show that each ton of raw liquid colored fiber can save water consumption of 140 cubic meters, reduce COD emissions by 56 kilograms, and reduce overall energy consumption by 70%.
A reduction in energy consumption also means a reduction in costs. According to the introduction, considering the difference of light color, medium color and dark color, the cost of the colored liquid of the raw liquid is 30% to 50% lower than the cost per ton of the dyed fiber.
Therefore, the raw liquid coloring fiber has very good ecological value and economic benefits. According to estimates, by 2020, if the production of raw liquid coloring fiber can be doubled to 10 million tons/year, it can save 1 billion tons of water, which is equivalent to the water volume of the South-to-North Water Transfer Project.
At the same time, the fabric woven with the raw liquid coloring fiber has the characteristics of uniform coloring, good color fastness, high light fastness, high washing fastness and unique style. At present, the raw liquid coloring fiber has been expanded from the raw liquid colored polyester to the fields of nylon, acrylic, polypropylene, aramid, spandex and the like. Among them, the raw liquid colored polyester is currently ranked first in the raw liquid coloring fiber.
It can be found that the raw liquid coloring fiber with remarkable water-saving and emission reduction effect, low production cost and superior performance has strong competitiveness and vitality in the color spinning industry, and the prospect is very bright.
