Staple dyeing is a dyeing technique mainly used for natural vegetable fibers (such as cotton, linen, hemp, ramie...), natural animal fibers (such as merino wool, lambswool etc), including the so called natural luxury fibers , that is alpaca, angora, cashmere, mohair, vicuna, silk, lama, camel hair, beaver hair, deer hair…), synthetic fibers (nylon, polyester, acrylic, modacrylic, aramid and meta-aramid fibers also in microfibers, ...), artificial fibers (bamboo, viscose, acetate, triacetate, lyocell, modal...) or feather and down.
Staple dyed fibers are used in different processing techniques in the textile production chain. For instance, after being processed through carding or open end spinning, fibers become yarn and later textiles for clothing or furniture. Other processing techniques for staple dyed fibers are used to make nonwoven fabric, fake fur, felt, needlepunched fabrics, etc.
The staple material for carded spinning can also come from regenerated scrap, cloth and byproducts of other textile productions. The fibers thus recovered, once suitably processed, will be used to make yarn for knitting and clothing. These fibers, generally known as regenerated fibers, have always been a typical product of the PRATO area.
In addition to dyeing, other treatments are carried out, such as:
- Flame-retardant Treatment
- Anti-moth treatment
- Antibacterial Treatments
