Made from cotton linter, Asahi Bemberg is a unique regenerated cellulosic fiber that features both a degree of "gentleness unique to natural fiber" and the "functionality of a man-made fiber." It is extensively used in diverse fields such as high quality linings and lingerie, as well as in apparel applications. It can also take various forms other than yarn and staple fiber. Among these examples are Bemliese, a binder free spunbonded nonwoven fabric, as well as a hollow fiber for artificial kidneys, each having earned on outstanding reputation in their fields. Asahi Chemical is the sole Asahi Bemberg manufacturer in Japan, and maintains the world's largest outputs. We annually produce 25,000 tons of Asahi Bemberg, filament and staple combined, to meet the ever increasing users' demands of our markets.
Asahi Chemical will continue to develop novel and innovative products to fulfill market needs into the coming 21st century, always keeping "ecologically friendly materials" as a high priority.
The raw material of Asahi Bemberg is linter available from cotton (an annual plant). Cotton linter can be produced at one-year cycles. Therefore, Asahi Bemberg does not contribute to environmental disruption such as deforestation seen in some wood pulp operations (raw material for rayon fiber).
Structure of the Cotton Ball
Cuprammonium rayon is a regenerated fiber well familiar under the brand "Bemberg". While viscose rayon and acetate of the same variety are made from pulp, cuprammonium rayon uses cotton linter at its main material. So "Bemberg" is ecologically safe, being free from environmental contaminants. This is the most suitable material for lining.
Main Characteristics of Bemberg
1. Bemberg is made up of fine denier, circular cross-section filaments, and its soft touch and drape are the closest to silk.
2. Its fine, elegant luster makes Bemberg the most suitable material for high-class fabrics.
3. Its superior moisture absorbing and releasing property and anti-static characteristic provide a refreshing feeling, and the garment does not cling to the body.
4. As Bemberg is a breathing fabric, it leaves you feeling cool and refreshed. That's the secret to its comfort.
Fabric used for linings must have the capacity to absorb moisture. Bemberg exceeds all other fabrics in this capacity. When we consider the ability to release moisture, Bemberg again surpasses other fabrics in the speed of recovering the standard moisture regain.
Ability to Absorb Moisture
Moisture regain of fiber when the temperature and humidity are changed to 30 C(86 F), 100% RH after being kept at 20 C(68 F), 65% RH for 24 hours.
Ability to Release Moisture
Moisture release when the temperature and humidity are changed to 20¢J(68¢K), 65% RH after being kept at 30¢J(86¢K), 100% RH for 24 hours.
Static Electricity
The occurrence of static electricity depends on the moisture regain of the fabric. Bemberg develops a charge of only 500 volts after one minute of rubbing, and this charge soon dissipated. With other fibers, static electricity doesn't dissipate nearly as quickly.
