Yarn with fluctuations in denier

The innovation concerns a yarn with fluctuations in titre.

Yarns with fluctuations in titre are made from a wide variety of synthetic thread materials known. They are usually produced by either conveying the spinning mass to the nozzle irregularly or by conveying the thread that is created is withdrawn in an irregular manner. Apart from the fact that such threads require a very high technical effort, they are. In the former case, knobs are practically always of the same thickness, while in the latter case they are usually not made of simple thread thickenings, but consist of nodules that are not always wanted. Besides that the irregularity in the order of the thickened threads or knobs must be controlled by corresponding complicated devices so that the periodic recurrence of certain distances and thus the creation of so-called images on the finished product are not avoided can be.

The object of the innovation is to find a thread with fluctuations in titre, which can be produced in a simple manner and which also has the thread thickenings with regard to the distances and the diameter in an ideal statistical distribution and which can be obtained through special conditions when drawing the undrawn material . The object of the innovation is accordingly a yarn with fluctuations in titre, which is characterized in that it is based on an elongation at break of 30 % to 80 %, preferably 35 % to

65% and a boiling shrinkage of 20 to 50 % stretched polyester threads, the number of thickened points 15 to 35, preferably 20 to 30 per meter and the distance between the adjacent thickenings is 0.5 to 8, preferably 0.8 to 6 cm, whereby the thickened and the thin areas can be colored differently.

The innovation is explained in more detail on the basis of the samples provided.

Pattern 1 (74 A i) is a test slide made from the thread according to the innovation. The thread is a polyester yarn with a nominal denier of 45/18.

For the in sections 1, 2, 3 and 4 (by dark horizontal line divided) the following values apply to each processed thread:

Dyeing was done with a red disperse dye (commercially known as RESOLINROT FB).

Pattern 2 (7 ^): This pattern differs from pattern 1 in that a thread with a different titer (68/24 nominal) is used. The associated values are:

It was dyed with the same dye as in sample 1. Thereby The titer fluctuations are significantly more pronounced than with the thinner thread. With a stretching of 1: 3.37 they can still be seen, while in pattern 1 they had already disappeared.

The patterns 3, ^ and 5 show tissue sections, in which in each case Weft the renewal yarn was processed. The titre and draw ratio can be found on the label. The associated other values can be taken from the tables above. The same dye was used for staining.

The fabric samples show the thread according to the innovation only in the weft. Ever however, depending on the desired effect, it can also be used in warp or warp and weft. Also in the manufacture of knitwear the thread can be processed alone or together with other types of threads.
