Double jersey machines

Double jersey machines The elastomeric fabrics produced by double-knit machines show distinct face and back stmctures. The fabrics with double or triple layers in some end uses can also be produced by the machines. All double-knit stitches, including double jersey, pique, French pique, ottomans, twills, needle outs, and flat back rib stmctures can be produced using elastic yams. The stitches have width or both width and length stretches using lay in, knit in, or plaiting carrier systems as mentioned above for the elastic yams in bare and covered types. 

The field of industrial plasma engineering has grown in recent years. The uses are motivated by plasma s ability to accomplish industrially relevent results more efficiently and cheaply than competing processes. The research program concerning plasma treatment of textile materials was launched at the Polish Textile Institute in 1973 to improve the soil release properties of double jersey fabrics from textunsed polyester yams. The first experiments with wool date back to 1980 to replace the chlorination in fabric preparation for printing. Tliree machines for continuous plasma treatment of wool top have been developed as follows ...

The two needle beds of the double-jersey flat-bed machine are arranged at an angle of about 90° to one another (Fig. 5.10, left). The needle beds are arranged horizontally to one another on purl-stitch flat-bed knitting machines so that the cams are directly opposite to one another. This allows the transfer of the double-tongue needles from one needle bed to the other (Fig. 5.10, right). Purl or plain stitches appear...
