Bio-based materials from corn and straw can not only make plastic, but also clothes

Original title: from corn, straw biological-based materials not only to do plastic, but also to make clothes
corn, straw and clothing, home, it sounds irrelevant, but is quietly related. Corn and even straw processed into a new type of biodegradable materials, can be spinning into yarn to make clothes, can also be processed into daily necessities, plates.
Reporters from the 2nd China Bio-based Materials Industry Development Conference was informed that China's enterprises "run through" from corn to poly lactic acid, fiber, and in home textile, clothing and other fields to carry out practice, made into shopping bags, tableware and sportswear. This new material is coming into your life.
limit plastic let this material into the public eye
In early 2020, the National Development and Reform Commission and the Ministry of Ecological Environment issued the Opinions on Further Strengthening the Control of Plastic Pollution, clear a series of plastic limit "timetable". With poly lactic acid materials made from corn and straw processing as the representative, bio-based materials with biodegradable functions quickly enter the public eye.
is a bio-based material? An expert from the China Textile Industry Federation describes it as "from environmental protection to environmental protection". Taking polylectic acid as an example, from corn, fiber extraction, production and application are not only circular economy, but also effectively play the characteristics of material antibacterial.
other particles converted into microplastics, polylectic fiber waste can be degraded to carbon dioxide and water, is completely biodegradable and truly environmentally friendly." Li Zengjun, an expert with the China Chemical Fiber Industry Association, said that the Central Economic Work Conference will make carbon peaking and carbon-mediuming one of the key tasks to be done in 2021, and bio-based materials are of great significance to environmental protection.
the prospects for this? "In 2020, China's synthetic resins increased slightly, in 2019 the five general-purpose resins increased by 7.2% over the previous year, the rapid development of the plastics industry is a major trend." Ma Zhanfeng, vice president of the China Plastics Processing Industry Association, said the ban is not a ban on the entire plastics industry, but rather an alternative to and improvement of some non-degradable parts of the plastics industry through biodegradable materials. To a certain extent, how much industrial space, how much new material space.
experts believe that the daily life of the use of many petroleum-based chemical fiber, membrane products, in the natural environment is difficult to decompose. It is time to promote the standardization and industrialization of bio-based materials.
technology has gradually had the basis of industrialization
the development of bio-based materials represented by polylactic acid, to increase the supply of green products, reduce the dependence on petrochemical resources, etc. have greatly helped, but also once faced with propylene ester generation technology difficulties, high production costs and other issues.
, however, in the relevant departments, scientific research institutions, front-line enterprises in practice, the problem is being solved. Reporters found that some enterprises have begun to lay out, some domestic enterprises through the low-cost production of poly lactic acid raw materials of the whole line of technology.
December 26, Anhui Fengyuan Group's second module annual output of 500,000 tons of lactic acid, 300,000 tons of polylectic acid project started. Previously, the annual output of 50,000 tons of poly lactic acid project has been put into production. In order to strive for a stable supply of raw materials, Shandong Zhengkai new materials, Jiangsu Yueda home textile and more than a dozen enterprises have planned to build a factory near the production base.
"At present, the standardization and industrialization of the bio-based materials industry is advancing rapidly, and recently the country has issued a number of specific terms and product catalogs for the development of bio-based materials products to create market space." Ma Zhanfeng said that these have made bio-based materials gradually have a large-scale industrialization of the basis.
breakthrough in the bio-based materials industry, represented by poly lactic acid, to further promote the high-quality development of China's bio-based materials industry. Wang An, a member of the Chinese Academy of Engineering, said.
market also needs to work together to
industry to develop, the market is critical. Industry experts believe that, on the one hand, to continue to strengthen technology and production, quality and other stability, on the other hand, should also strengthen the market awareness of new materials, so that they enter the market, to withstand the market test.
"In layman's terms, poly-lactic acid materials made of corn and straw are roughly in two directions, one is plastic and the other is cloth." In recent years, the relevant person in charge of the Anhui Municipal Development and Reform Commission told reporters that in recent years, the city has provided support in the fields of policy, capital and platform, and comprehensively promoted the use of recyclable, recyclable and biodegradable membrane bags.
In terms of fabrics, experts believe that poly lactic acid fiber has a weak acidity similar to human skin, in underwear, home textile and other fields of application has advantages, but compared with chemical fiber products, scale is not enough.
" polylactic acid fiber price is higher than the commonly used polyester fiber. Polyester fiber is a thousand tons, polylactic acid is currently several tons. "Li Zengjun believes that it is very important to increase production capacity and reduce production costs.
from the factory into the market, but also to better play the role of policy coordination, standard leadership, and so on, correctly guide the promotion and application of bio-based materials.
" 30 to 40 fibers is equivalent to the weight of a hair, can be seen in the exquisite production process. It is currently extracted from corn, and the next step is to make straw, which also requires upgrading the process. The head of the China Chemical Fiber Industry Association said that the development of new materials should be patient, do a good job of fine layout, and with the help of new business models to better promote to consumers.
