Description

Textile fabrics of aramid fibers and their use

Description:

The invention relates to a textile fabric of aramid fibers and its use.

Textile fabrics of aramid fibers and their use in the manufacture of e.g. of antiballistically active textile fabrics are known. These fabrics typically contain aramid fibers which have been provided with equipment comprising a polyglycol ester of oleic acid during their manufacture. Such equipment is available under the designation Leomin OR from Clariant, DE. US 4,652,488 describes the equipment of aramid fibers with Leomin OR.

When textile fabrics of aramid fibers are to be processed for the production of an antiballistic article which has to develop its required antiballistic effect even when wet, it is necessary to render the textile fabric made of aramid fibers water-repellent. However, when a fabric of aramid fibers provided with a polyglycol ester of oleic acid is provided with a water-repellent finish, the fabric has only the insufficiently low v ₅₀ values of a non-water-repellent finished fabric comprising aramid fibers when wet. Therefore, it has hitherto been necessary, prior to the application of the water-repellent finish, to the textile fabric of aramid fibers, the equipment comprising a polyglycol ester of oleic acid to a residual content of <0.1% by weight and to mask the remainder of the equipment left over. The necessary procedure consists of the following process steps:

1) installation of the supplied in roll form textile fabric, usually a fabric in a washing machine (jigger);

2) filling the jigger with fresh water;

3) heating the fresh water to 80 ° C;

4) adding a surfactant suitable for washing the equipment;

5) Prewash in 2 passages, with each passage off

5 ₁ ) unwinding the fabric from the roll,

5 ₂ ) passing the fabric through the surfactant / water mixture,

5 ₃ ) winding the fabric on another roll,

5 ₄ ) unwinding the fabric from the further roll,

5 ₅₎ passing the tissue through the surfactant / water mixture, and

5e) winding the fabric on the roll

consists;

6) drain the wash water from the jigger;

7) filling the jigger with fresh water;

8) heating the fresh water to 80 ° C;

9) adding a surfactant suitable for washing the equipment;

10) Wash in 10 passes, each passage from the o.g.

Steps 5i to 5e exists.

1 1) drain the wash water from the jigger;

12) filling the jigger with fresh water;

13) heating the fresh water to 80 ° C;

14) Rinse in 3 passages, each passage from the above mentioned.

Steps 5i to 5e corresponding steps;

15) draining the rinse water;

16) filling the jigger with fresh water;

17) heating the fresh water to 80 ° C; 18) adding an agent to mask the remainder of the equipment remaining on the fabric;

19) 10 masking passages, each masking passage consisting of the above-mentioned. Steps 5i to 5e corresponding steps;

20) draining the masking agent-containing water from the jigger;

21) filling the jigger with fresh water;

22) heating the fresh water to 80 ° C;

23) Rinse in 4 passages, each passage from the above-mentioned.

Steps 5i to 5e corresponding steps;

24) removal of the roll with the fabric from the jigger;

25) passing the tissue through a drying oven at 170 ° C with a tissue dwell time of about 60 seconds;

As already mentioned, in order to achieve the required v ₅₀ values, it has only been possible, after passing through the abovementioned washing and masking process, to provide the textile fabric of aramid fibers with a water-repellent finish, ie the fabric

- to pass through a bath of water and a water-repellent agent,

- to squeeze

- to dry and

- heat treatment.

The o.g. Washing and masking process is not only very expensive in terms of the time, energy and water required, but also requires a considerable amount of quality control. If the quality control after step 15) indicates that the residual content of the equipment is> 0.1% by weight, at least some of the steps 1) to 15) must be repeated until the permitted residual content of equipment of <0.1% by weight .-% is achieved.

Consequently, there is a need to provide the above-described washing and masking method for providing a water repellent application By means of suitable textile fabrics made of aramid fibers, either completely superfluous or at least significantly reduce the processing costs.

Therefore, the object of the present invention is to render the abovementioned washing and masking process either completely unnecessary for providing a textile fabric of aramid fibers which is suitable for the application of a water-repellent agent, or at least significantly reducing the cost of the process.

This object is achieved by a textile fabric made of aramid fibers, which are equipped with a lubricant, wherein the lubricant comprises a carbonic acid polyester.

Surprisingly, the textile fabric according to the invention can be rendered water-repellent directly, ie omitting the 25-step washing and masking process described above, and yet shows similarly good v ₅₀ values not only in the dry but also in the wet state in the case of bullet and shatter bombardment like the fabric described above with aramid fibers with a polyglycol ester of oleic acid comprising equipment, which still has to undergo the above-described 25 washing and masking steps in front of its water-repellent finish.

In the case of fragmentation, the textile fabric according to the invention, which is washed as described in the initially described process with steps 1) to 15), but in step 10) only 6 passages are carried out and in step 14) the fabric is sprayed with water only and not and the masking steps 16) to 24) are omitted, even a v ₅₀ value higher than the v ₅₀ value of a fabric having aramid fibers with a polyglycol ester of oleic acid comprising equipment before its water-repellent finish, all of the above-described 25 wash and mask steps must be completed.

Thus, those skilled in the art, the fabric of the invention is provided, from it

- Produce either a water-repellent finished textile fabric, which has similar good v ₅₀ values as the fabric described above with aramid fibers with a polyglycol ester of oleic acid comprehensive equipment, but before its water-repellent Equipment has to undergo the previously described 25 washing and masking steps,

or, with partial abandonment of the hitherto necessary washing process, in the absence of the hitherto necessary masking process, produce a water-repellent finished textile fabric which has even higher v ₅₀ values than the textile fabric with aramid fibers described at the outset comprising a polyglycol ester of oleic acid-comprising equipment, but before his water-repellent equipment has yet to undergo the previously described 25 washing and masking steps.
