American company cooperates with Lenzing to develop new blended flame-retardant textile materials
PBI Fiber Materials Company of the United States and Austrian Lenzing Company cooperated to develop a blended chemical fiber fabric-type fire-proof fabric material mainly composed of Tencel, called PBI Base Guard™. This material can be made into lightweight and comfortable underwear as well as durable High temperature and flame resistant gas station work clothes.
PBI High Performance Fibers, located in Charlotte, North Carolina, USA, produces fire-resistant fiber polybenzimidazole (PBI) that can be used to protect astronauts, firefighters, first responders, military personnel, as well as petrochemical and equipment workers and have been producing this product continuously for 40 years. PBI fiber was created in the 1960s. The fiber has superior properties, and PBI can find the best solutions in areas that other plastics cannot achieve. Compared with other plastics used in this field, PBI is lighter in weight, can withstand high temperatures and strong fires, does not melt, has minimal thermal shrinkage, does not burn or break, and does not release harmful gases when the flame is extinguished. In addition, it is acid and alkali resistant, flame resistant and self-extinguishing, and has good mechanical and electrical insulation properties. It has good sensitivity and breathability, has the same shrinkage rate as cotton, and has good humidity control capabilities, and can be used in underwear manufacturing. PBI Base Guard is a recently developed blended chemical fiber fabric product that uses 20% PBI, 70% Lenzing FR® and 10% Tencel®, so it has attracted industry attention. They take advantage of Lenzing’s fire resistance and the softness of the other two fibers, hoping to make it the world’s best choice for underwear fabrics. PBI High Performance Fiber Company is a century-old company in the United States that specializes in yarn-woven fabrics and has also developed numerous T-shirts, underwear and polo shirt brand products.
It is said that PBI Base Guard can be applied to military uniform fabrics. It is low-cost, highly fire-resistant and comfortable. The company found that arc flash testing showed that PBI Base Guard has good protective performance. Compared with other fire-resistant products, it is particularly comfortable to wear, and more and more areas can use this material. Now, they are also starting to attract investment from all over the world to push it into other markets, such as industry and utilities.
This is a yarn jointly developed by the company and Farfang Yarn Company. It is also a good product of fiber blended chemical fiber fabrics. Falfang Yarn Co., Ltd. understands and is good at manufacturing fibers. It has excellent fiber technology for blended chemical fiber fabrics, which can ensure a uniform and appropriate amount of each fiber and a high pass rate for spinning yarn tests.
Farspun Yarn Company and PBI Company are jointly committed to solving the problem of spinning yarn finishing. Its technology ensures that the product can withstand 50 cleanings without changing its performance. Knitted fabrics include lightweight casual shirts and heavier cotton fabrics suitable for polo shirts and gas station T-shirts. In addition to being used in the military, first aid, firefighting and industrial markets, their products are also expected to enter the racing workwear market.
