[Chemical Knowledge]：Properties, uses, upstream and downstream raw materials, storage methods, characteristics of acrylic fibers

Acrylic fiber properties

Acrylic fiber, also known as polyacrylonitrile fiber, is a synthetic fiber whose chemical structure is mainly polymerized from acrylonitrile monomer. Acrylic has good strength and elastic recovery, the texture is soft and close to wool. It also has good wear resistance and light resistance, and can be exposed to the sun for a long time without aging. Acrylic has good chemical resistance, acid, alkali and other general chemicals have strong resistance. Compared with other synthetic fibers, acrylic also has good thermal properties, so it is often used to make winter clothing and thermal materials.

acrylic fiber use

Due to its unique properties, acrylic fibers are widely used in the textile industry. Acrylic can be used to make all kinds of clothing, especially knitwear, sweaters and sportswear. Because of its wool-like feel, acrylic is also commonly used in the production of various types of blankets, carpets and furniture decorative cloth. Acrylic's high light and weather resistance makes it an ideal material for outdoor tents, awnings and other outdoor products. In addition, acrylic fibers are also used to make filter materials and industrial fibers, which are widely used in environmental protection and industrial production.

Upstream raw materials

Acrylic is the main raw material of acrylonitrile. Acrylonitrile is an important organic chemical raw material, which is mainly produced by propylene ammoxidation. In this process, propylene reacts with ammonia and oxygen in the air under the action of a catalyst to form acrylonitrile, hydrocyanic acid and water. Due to the high requirements for catalysts and reaction conditions in the production process of acrylonitrile, the production process is more complex and has certain technical barriers. In addition to acrylonitrile, the production of acrylic fibers also requires initiators, solvents and other additives. The quality and purity of these chemicals have an important impact on the quality of the final product.

Downstream Products

As a basic chemical raw material, acrylic fiber is widely used in the production of various downstream products. Textiles are the main downstream products of acrylic, covering many fields such as clothing, home textiles and industrial textiles. Due to its excellent warmth and comfort, acrylic fiber occupies an important position in the clothing industry. Acrylic fibers are also widely used in the field of home textiles, such as sheets, blankets and carpets. Acrylic fiber has good chemical stability and wear resistance, so it has also been used in industrial fields, such as filter materials and reinforcing fibers.

acrylic fiber storage method

Acrylic fibers need to be protected from moisture, light and high temperature during storage. Acrylic fiber should be stored in a dry and ventilated environment to avoid mildew or performance degradation caused by moisture. Acrylic should avoid long-term exposure to strong light to prevent ultraviolet rays from aging and strength degradation of the fiber. Acrylic fiber should be stored in a suitable temperature environment to avoid damage to the physical properties of the fiber caused by high temperature. In the actual storage process, acrylic fibers are usually in the form of rolls or packages, and placed in waterproof and dustproof bags to ensure their performance and quality.

acrylic fiber market analysis

In recent years, the market demand for acrylic fiber has grown steadily, mainly due to its wide range of applications and excellent performance. The continuous development of the global textile industry and the increasing demand for high-performance synthetic fibers have promoted the expansion of the acrylic fiber market. With the increasing awareness of environmental protection, the application of acrylic fiber in the field of filter materials and industrial fibers is also expanding. The acrylic fiber market also faces challenges such as fluctuating raw material prices, complex production processes and increasingly stringent environmental regulations. In order to meet these challenges, acrylic fiber manufacturers need to continuously improve their technical level, optimize production processes, reduce production costs, and actively develop new products to meet market demand.

future development trend

Looking ahead, the acrylic market will continue to grow. With the continuous development of the textile industry and the improvement of people's living standards, the demand for acrylic fibers in the field of clothing and home textiles will further increase. The application prospect of acrylic fiber in the field of industrial fiber and filter material is also very broad. With the progress of science and technology, the production process of acrylic fiber will continue to improve, and the research and development of new catalysts and reaction conditions will further improve the production efficiency and product quality of acrylonitrile. Acrylic fiber production enterprises should also actively explore the path of sustainable development, strengthen environmental protection measures, and reduce the environmental impact in the production process.

Conclusion

Acrylic fiber, as an important synthetic fiber, plays an important role in modern industry and life with its excellent performance and wide range of applications. Despite some challenges, with the continuous progress of technology and the increase of market demand, the development prospect of acrylic fiber industry is still broad. In the future, acrylic fiber manufacturers need to continue to innovate and improve production processes and product quality to meet the growing market demand and promote the sustainable development of the industry.
