Abstract: A woven fabric, especially a jeans fabric, with a ground fabric (140) and a laid-in selvedge (135) is produced. In this regard, the end sections (138) of the weft threads (137) are folded over at the edge (147) of the woven fabric and are again guided back into the woven fabric. Thereby the ends (139) of the weft thread end sections (138) can be dispersed over a range a and cause optical disturbance.

Abstract: A selvedge-forming device has a tuck-in needle having, at least in the end part introducible into the shed, a wedge shaped cross-section. The needle also has an elongate yarn entry aperture whose major dimension extends in the direction of the length of the end part of the needle. The end part also has an end face which leads in the direction of entry into the shed and which co-operates with the long side near the reed to form a tip pointing away from the shed apex. The needle can make pivoting movements out of the shed very close to the shed apex so that the weft yarn end is tucked in correspondingly close to the shed apex. Because of the elongate shape of the aperture the weft yarn end can be bent readily and can therefore be threaded into the aperture with a reduced blowing pressure of a threading nozzle.

Abstract: The tuck-in needle of a mechanical selvedge-forming device has a catcher for a yarn end following a needle tip. The catcher is subdivided into an entry zone and a trough screened from the entry zone by a hook disposed towards the trough. In its catching movement the needle is moved only towards the weft yarn so that the yarn moves into the entry zone of the catcher. The weft yarn then slides inclinedly over the outside of the hook until passing by way of the hook tip into the catcher interior. The weft yarn can be drawn into the cloth selvedge in this position. This construction enables the tucking-in to be very simple.

Abstract: A process for forming crepe fabrics on a shuttleless loom is provided which includes temporary stabilization of highly twisted (e.g., 40-70 TPI) filament yarn. To this end, hot melt size is applied at a predetermined temperature in predetermined amounts (e.g., add-on of about 10.5-13.5%) immediately after twisting so as to reduce the liveliness of the yarn and to thereby permit it to be woven. After weaving, the yarn stabilization is reversed by a desizing operation. The fabric is subsequently heat treated to develop crepe characteristics.
