Abstract: Techniques produce intertwining knots in a multifilament thread. In such techniques, an air stream pulse is generated by a nozzle channel opening into a treatment channel periodically with an interval between successive air stream pulses. During an interval, the air stream pulse is directed transversely onto the thread guided in the treatment channel so that a continuous sequence of intertwining knots is produced in the running thread. An auxiliary air stream is generated continuously or discontinuously and the auxiliary air stream and the air stream pulse are blown in together into the treatment channel.

Once the crimp is applied, families of the crimped yarn are utilized as a layer or layered to produce a soft armor form.

Abstract: In this invention, we found unexpectedly that when PTT fiber is drawn,textured and set under certain conditions, the fabrics made from textured fibers by this texturing process possess stretch and hand which is much better than current commercially available PBT and PET stretch fabrics, and better than PTT textured fibers made under similar conditions without the setting step. Specifically, the invention describes the spinning of PTT polymer into yarn with an elongation of 60 to 160% and draw-texturing the yarn using a false-twist draw-textured yarn machine at a draw ratio of 1.02 to 1.6 and a yarn temperature of 120 to 160° C., preferably 130 to 150° C.

Then knitted fabrics are dyed, tentor-set, and finished with fabric softener. This invention is different from the above teachings in that the PTT yarn is draw-textured in a false-twist machine.

The mixed yarn is manufactured by an air jet texturing process.

The invention relates to a new method of manufacture and to an apparatus, or an entire machine, with which the known loop yarn or the new mixed yarn can now be manufactured selectively.
