Textile thread and process for its manufacture

The present invention relates to a textile thread made from a synthetic starting material, characterized in that it comprises a soul which is surrounded by ribs which have notches which are distributed along their entire length.

The invention also relates to the method for producing the textile thread defined above,

JPC / gs / Schenker
(9610)

109842/1810

which is characterized in that the notches at certain intervals in the ribs of the synthetic material starting with a profiled thread.

The invention is distant .- an apparatus for Carrying out said method, characterized in that it comprises at least one knife which is placed around the Thread is driven when it performs a longitudinal displacement so that it is distributed spirally along the thread Notches can be cut into the ribs.

This thread can be used e.g. for the manufacture of ropes of which at least certain twisted threads visible on the surface are those with Notches are provided. This thread can also be used to make curlers or any kind of fabric to serve.

The accompanying drawing shows schematically and by way of example an embodiment of the textile thread according to the invention as well as some of its uses. Show in it:

1 shows a diagrammatic, greatly enlarged view of a section of the textile thread according to the invention,

FIG. 2 shows a cross section of the textile thread along the line II-II of FIG. 1,

FIGS. 5 and 4 show a side view of two design variants this textile thread

199842/1610

Fig. 5 shows a section of a rope using of the thread according to the invention was produced.

With reference to FIGS. 1 and 2, the thread shown is made from a synthetic starting material such as polyamide fiber or from any other material of this type. This thread comprises a core 1 with a basically circular cross-section with a diameter d ". This soul _! is surrounded by ribs 2 , in the embodiment shown there are three. These ribs 2_ extend * along the entire length of this thread and form evenly distributed lobules around the core _1. The circle circumscribed around this lobule 2_ has a diameter d ₁ . The notches J5 are cut into the ribs at regular intervals. In the embodiment shown in FIG. 1, these notches j5 are arranged in a spiral along the thread and around it, for example with a pitch of 0.5 mm. The depth of these notches ji extends practically up to the diameter d ₇ shown in FIG. 2, which is slightly larger than that

Diameter d to avoid weakening the soul, which could break the thread.

The angle of the central plane of each notch can be between 10 and 90 ° with respect to the thread axis. This in FIG. 3 and 4 angles marked with - "<. may actually vary depending on Purpose of the textile thread vary. Fig. 3 shows an embodiment variant in which this angle

1098A2 / 1610

a value of the order of magnitude of 15 ° to form notches with a strong retaining force, while FIG. 4 shows a variant at which this angle is "* -. 90 °, to form notches with poor retention.

Of course, the number of lobes or ribs 2_ which the textile thread will have can vary from two to more than three lobes.

Such a textile thread can be produced after or during the profiling, e.g. with the help of a thread clip can be achieved or by cutting the notches at regular intervals, e.g. using a cutting knife, which is driven around the thread, during the longitudinal displacement of the latter.

This thread can be used in various fields. It can be used for the production of non-slip fabrics and ropes, such as curlers, carpets, brushes, brooms, and filters, are particularly advantageously used will.

FIG. 5 shows the section of a rope of which at least a part of the threads twisted on its surface consists of a thread of this type with notches as shown in FIG. The thread £ has notches 2 , the openings of which are arranged in a certain direction (upwards in Fig. 5), while the adjacent

10 9 842/1610

barte thread ΙΌ has notches j5, the openings of which are directed in opposite directions, namely downwards. Such a rope therefore has excellent anti-slip properties. Of course, it would also be possible to twist such a rope with threads whose notches J> have openings in the same direction, so that this rope would be slippery in one direction and non-slip in the other direction. Such ropes can therefore be used advantageously as a holding rope, in particular on ships. *

It would also be possible to use a rotating milling cutter or a gearwheel, which impresses its teeth in the ribs to form these notches, instead of the rotating cutting knife to design the notches j5 in the lobes of the thread with the core 1. After hot extrusion, this process could take place shortly before the material used to form the thread solidifies. It should be noted that the fabrics made with this thread can be used as scrapers, polishing agents, brooms, brushes, filters or as fabrics for special applications such as non-slip carpets.

The considerable retention capacity of such a thread is due to the large number of those distributed on each thread Notches ^ attributed.

In the manufacture of fabrics, these threads with notches 2 * ^{allow the} disadvantage of the threads slipping against one another

109842/1610

to avoid, which is particularly noticeable when using synthetic textile thread.
