Dialogue: Analysis of the application of cellulose fiber in the field of safety protection textiles

With the advancement of science and technology, the environment in which humans can get involved is becoming more and more complex, and their awareness of protection is becoming more and more intense. However, at present, domestic protective textiles are still at a relatively low level, and most of them are used for protection. The fabrics of fabric functional protection textile enterprises also point to foreign countries. The sales of such products are still at a relatively preliminary stage in the domestic market. How will the development of protective textiles develop in the future?

Today, with the theme of “Development Status and Trends of Safety Protective Textiles”, Lanjing Technical Consultant specializes in market research, fiber and technology innovation, product development, standard system construction, downstream application, and intelligent development. In the field, comprehensively interpret the status and trends of textiles for security protection.

Q: Please talk about the application status and development prospects of cellulose fiber in the field of safety protection.

A: I think that the blended fabric made of cellulosic fiber will be used to process protective clothing. This is because most of the intrinsic flame retardant fibers are synthetic fibers, and the fabrics processed with 100% of these fibers are not comfortable to wear. The addition of cellulose fibers can greatly improve wearing comfort. For ordinary clothing, the situation is basically the same. People prefer to wear clothing made of blended fabrics of cellulose fibers such as cotton, viscose, modal and tencel.

Lenzing uses this concept for protective clothing because many users work in hot climates or in difficult conditions or environments, such as the smelting industry (high ambient temperatures, strong thermal radiation) and the building fire protection industry. These industry employees need to be protected with multiple layers of clothing, and thermal stress is a focus of attention.

Q: Safety textiles are highly dependent on specialty fibers that provide protection. As a representative of flame retardant cellulose fibers, what are the technical features and advantages of LenzingTMFR? What types of products can be used to develop?

A: Lenzing has a very clear strategy in providing fibers that can meet a variety of protective functions. First, we need to understand the environment and needs of the user, and then we produce a product that suits their needs, because it is impossible to use a fabric or blend fabric to meet all needs. The main features of the Lenzing flame retardant blend fabric, in addition to increased protection, can also improve the comfort and breathability of protective clothing.

These features can be easily detected using the internationally recognized testing methods introduced by the renowned German Hohenstein Institute. Test results show that LenzingTM FR can help the fabric to increase the release of body heat and the absorption of sweat. By aligning LenzingTM FR with other high-performance fibers in a properly blended fabric with the right blend ratio, the product can be protected against a variety of end applications (including the outer fabric of fire fighting suits).

Note: Test methods refer to the standards DINEN31092 and ISO11092. The higher the Fi value, the stronger the sweat absorption capacity.

Q: What technical services does Lenzing have for downstream customers? Taking LenzingTM FR as an example, what initiatives does Lenzing help downstream customers to better use Lenzing Fiber to develop new products?

A: Lenzing's principle is clear, only to provide fiber to downstream users, not to sell yarn, fabric or clothing to avoid competition with our partners. Lenzing not only provides fiber, but also leverages its strengths and expertise to provide customers with a full range of services and support, including:

· Technical support at all stages of the process;

· The development of new technology products, which was previously tested in Austrian companies, is now tested in Hong Kong (Lanjing provides a full range of technical services in Hong Kong), and then certified by a third party, sometimes funded by Lenzing;

· Develop markets in emerging markets through global networks and long-term experience.

With experience and trust, Lenzing has established close relationships with many heavyweight downstream partners. This business model is forming and working in China. We have many world-class certified products that have entered China and other markets.
