Plant short fiber raw materials come from a wide range of sources and have good future market application prospects.

Plant short fiber is a bio-based composite material made from crop straw short fiber, bamboo short fiber, hemp short fiber, etc. as raw materials, and compounded with bio-based resins such as modified starch, soy protein glue, and polylactic acid. Plant short fiber is a new type of material with the advantages of high strength, light weight, energy saving and environmental protection, wide source of raw materials, and degradability. It can be used as an excellent substitute for plastics, glass, and ceramics.

With the advancement of technology and in-depth research, the types of plant short fibers have been continuously enriched. According to different matrix materials, plant short fibers can be divided into starch-based, soy protein-based, polylactic acid-based, etc.; according to different fiber types, plant short fibers can be divided into flax fiber, bamboo fiber, straw fiber, etc. Plant short fiber raw materials come from a wide range of sources. my country is a large agricultural country with an annual straw output of nearly 1 billion tons. Developing the plant short fiber industry can not only save resources, but also help improve the utilization rate of agricultural waste and protect the environment. In the context of increasingly serious environmental pollution problems, the use of natural materials has become a trend, and the plant short fiber market has good development prospects.

According to the “2022-2026 China Plant Short Fiber Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center At the beginning of the 21st century, plant short fibers were mainly used in disposable degradable tableware. Later, with the development of technology, the compounding of plant short fibers with other materials became the mainstream. Driven by this, plant short fibers have improved performance, quality, appearance, etc. Achieving great improvement, the application has gradually expanded to packaging, automobiles, rail transit, medical equipment, sporting goods, household appliances and other fields.

Under the strategic background of carbon neutrality and carbon peaking, the plant short fiber market has received greater attention, and the types of related products have become increasingly rich. At this stage, enterprises or institutions engaged in the research and production of plant short fibers in my country include Tongji University, Tianjin University of Technology, Sichuan Changsheng New Materials, Bofu Technology Co., Ltd., Huanke Innovation, etc.

Flax fiber is one of the earliest plant short fibers used. Flax fiber has multiple advantages such as strong hygroscopicity, fast heat dissipation, and friction resistance. It is an important raw material in the current textile industry. Flax is an annual herb. Globally, Canadian flax has high quality. my country is one of the major flax producing countries. The planting area in 2021 will reach about 95,000 hectares, mainly distributed in Gansu, Heilongjiang, Liaoning, Hebei and other regions.

Industry analysts said that plant short fibers have the characteristics of light weight, high strength and wide source of raw materials, and can be used as plastics, glass, As an excellent substitute for ceramics, under the strategic background of carbon neutrality and carbon peaking, the plant short fiber market has good development prospects. With in-depth research and technological advancement, plant short fibers and their products are becoming increasingly abundant, and their application fields are gradually expanding. In the future, the development of the industry will continue to improve.
