Abstract:

Extraordinary soft and fluffy knitted products may be obtained by a technology of weft-knitt-ed fabrics which we have developed and manufactured with the use of circular open-top-knitting machines. The knitting features obtained in this way raise the level of the clothing’s comfort of usage. This advantageous effect is the result of working-in a stream of untwisted fibres instead of the traditional yarn into the knitted fabric. The fibre stream, intended for the manufacture of the knitted fabric, is obtained as the result of roving which is drawn immediately before being fed into the knitting-zone of the knitting machine. This is done by using a drawing device which we have specially designed and constructed. The devices are mounted in each working zone of the knitting machine. Considering the decrease in machine efficiency caused by using the new technology, the manufacturing costs are higher than those for the classical technology. However, on the other hand, the possibility of using cheaper raw material than common yarn raises the economical effectiveness.
