Dryers for other textile applications

Considering that most non-electrically conductive (ie. dielectric) substrates containing water can be dried quickly, uniformly, efficiently and with optimal quality results by means radio frequency, during the years STALAM has developed and supplied specific drying equipment suitable to process a wide range of textile, technical-textile and related products.

Some of these special applications within the textile industry are listed below:

• the drying of bleached hydrophilic cotton fibres for medical, sanitary and cosmetic use;
• the drying of raw or processed / dyed hemp, flax, ramie, coir, jute and sisal fibres;
• the drying of wet-spun linen yarns on spools, either off-line on suitable pin trays or in-line with the spinning frame;
• the low temperature drying of raw silk hanks after the wetting / oiling process, before twisting;
• the drying of silk cocoons and silk wastes after carbonising;
• the drying of dyed elastic bands, narrow fabrics, lace, strings, cords, etc.
• the drying of dyed garments, sweaters, sport socks, leather items, etc. specifically when the tumbling effect is not desired;
• the drying of dyed fishing nets;
• the drying of woollen felts for clothing or industrial use, after impregnation, in the form of sheets and disks;
• the drying and pre-heating of defective or waste synthetic fibres (mainly PA, PES, PP) after washing, to be recycled in pellet form, off-line or in-line with the extrusion equipment;
• the drying of washed and hydroextracted thread waste and rags;
• the drying of short-cut, high-porosity reinforcement fibres (cellulose, aramide, glass, etc.);
• the drying of PU foam after wet casting, for medical use;
• the drying of latex foam mattresses, pillows, sheets, thin webs (LPC), etc. after vulcanisation, washing and hydroextraction;
• the drying of glass fibre and basalt fibre rovings and their derived products.

More details on the drying of foamed polymers and of glass fibres can be found in the “Technical Textiles” section of this web site.
