The PLA / Ingeo fiber is a staple fiber with a round cross-section and is obtained from natural, abundant, environmentally friendly and extremely sustainable raw material such as corn (corn starch). The corn fiber provides an excellent handling and easy processability as well as a high UV resistance.
The fibers have very good elasticity, crimp and form-stability, like polyester fibers, but they have a lower density. Additionally, the flammability is lower and the fibers are washable and biodegradable.
Lyocell fibers like viscose fibers belong to the cellulose fibers. Cellulose is gained from the naturally growing raw material timber. The lyocell fibers (Tencel) are manufactured with a natural spinning process which was delevoped by the Lenzing company.
The fibers have excellent dry and wet strength as well as absorbing properties which are even better than those of cotton. The fibers are soft and comfortable. The smooth structure feels almost like silk. Lyocell fibers are 100 % natural, breathable and biodegradable. Tencel is allergy-friendly because it is not an animal fiber and it attracts less dust than cotton.
Polyester nonwovens are characterized in particular by the fact that they are soft, light, supportive, elastic, have a high rebound force, are washable and suitable for tumble drying. Furthermore, polyester nonwovens have elastic and supporting properties and a high strength recovery.
In our company, we produce exclusively thermally bonded polyester nonwovens. Based on the process, which we use since 1992, chemical spray bonding can be completely abandoned. Therefore, we ensure that our nonwovens do not contain any harmful substances and materials that are dangerous to health. During the thermal-bonding process, the nonwoven is heated to 130° Celsius and is therefore hygienically safe. Polyester nonwovens are especially recommended for products which are used by people with allergies.
Besides the standard staple fibers we have polyester fibers without optical brighteners, low antinomy polyester, siliconized hollow fibers and special polyester fibers with an antibacterial or flame-retardant finish.
One of these special fibers is Trevira CS with its flame-retardant finish. Even after several washes, the flame-retardant properties remain. Besides the flame-retardance, the textiles need to fulfill the testing standards of DIN 4102 (B1 standard).
