Germany-based circular knitting machinery maker Terrot GmbH reports its patent-pending F132-AJ technology provides a direct spin-knit process comprising a modular air-jet spinning system that can be fitted to all Terrot single- and double-jersey machines.

The system features spinning units in a creel-type arrangement surrounding three sides of the knitting machine. The spinning units contain the roving-to-spinning process, and the yarns are fed to the knitting machine as in a conventional process.



Combed cotton, man-made and blended fiber yarns ranging from Nm 40 to Nm 100 can be produced. According to Terrot, the system can be used for high system densities, diameters up to 120 feeders, and gauges from E20 to E36. The spinning system can be equipped with 24, 32 or 40 spinning heads per unit; and features integrated flyer, fluff removal and monitoring process. Fabrics produced feature a soft hand and good dyeability; and elastane plaiting also is possible, the company reports. The speed factor ranges up to 600 and unfinished fabric production ranges up to 360 kilograms per 24 hours based on operation at 20 revolutions per minute and 30 inches.

In addition, Terrot reports, the F132-AJ system offers the following advantages: space requirements reduced by 33 to 40 percent; energy reduced by up to 50 percent; investment costs reduced by up to 30 percent; and production costs reduced by up to 50 percent.
