Definitions
- the thread then travels through a distance of 70 cm. in the spinning bath and is withdrawn by a first roller at 23 1n./min.
- the thread then travels through a second bath with 6 g./l. H 80 at a temperature of 90 C. and is withdrawn by a second roller at 46 m./min.; that is to say, it is stretched by 100%.
- the thread travels from 3 l the second roller onto a bobbin and is collected thereon.
- the thread is then rewound, washed, finished and dried. It has the following textile data:
