Description

Knitted fabric

The innovation relates to a knitted fabric, for example for a stocking, a support stocking, a medical compression stocking, a pair of tights, a pair of support tights or a pair of medical compression tights according to the preamble of claim 1.

Knitted fabrics, including those for stockings and tights, have basically been known for a long time.

Support stockings, compression stockings, etc. are used preventively for relief, but also in cases of acute venous diseases or when there is a risk of thrombosis.

0 For the additional treatment of patients wearing such support stockings or compression stockings, it is also necessary under certain circumstances to administer injections.

or to pass electrodes, tubes, etc. through the knit of the stocking.

For this purpose, a hole or slit must be cut into the knit of the stocking and the opening thus created must then be sewn up in order to
To prevent the formation of ladders. This understandably involves a considerable amount of work.

The innovation is based on the task of creating a knitted fabric in which the creation of the aforementioned holes
or slots at specified positions without major effort.

To solve the problem, according to the invention a knitted fabric having the features of claim 1 is proposed.

Advantageous embodiments emerge from the subclaims.

The innovation is explained below with reference to the
The drawing figure explains this, for example. It shows:

area with a water-soluble thread inserted and a second area with a melting thread surrounding this first area.

As can be seen from Fig. 1, a water-soluble thread 13 is incorporated into the usual knitted fabric 10, for example consisting of textile threads 11, in a certain first area 12 instead of the usual thread 11. This is done in a manner known per se with the aid of appropriately controlled thread guides and therefore does not need to be explained further.
10

In a corresponding manner, a melting thread 15 is additionally incorporated around this mentioned first region 12 - with the water-soluble thread 13 - in a second region 14 surrounding this first region 12 with the aid of appropriately controlled thread guides.

This results in an inner first region 12 with the water-soluble thread 13, which is surrounded by a surrounding second region 14 with a melting thread 15.

This means that during the production of the knitted fabric or stockings, etc., a passage in the form of a hole or a slit is prepared at the desired locations.

0 With the help of a targeted heating of the surrounding second area 14, the melting thread 15 in the second area 14 is then heated above the melting temperature at the desired locations. This leads to the formation of a melted

zen and then re-solidified, but elastic border of the first area 12. This prevents the formation of ladder stitches after the subsequent dissolution of the water-soluble thread 13 in the first area 12. 5

In a subsequent washing process, the water-soluble thread 13 located in the first region 12 within the surrounding second region 14 is dissolved and thus removed. 10

The result is a knitted fabric with holes or slits in specified places. Since these are already incorporated during the production of the knitted fabric, the additional effort required is minimal.

Electrodes, electrical cables, supply lines, hoses, etc. can be passed through the holes or slits in the knitted fabric. This makes it possible to continue necessary treatment of the corresponding body parts and diagnostic measures even while wearing the knitted fabric.

The holes and slits can also be provided in knitted fabrics with electrically conductive threads that serve as electrical shielding. Of course, care must then be taken to ensure that the electrically conductive threads 0 are not impaired in their effect by the holes or slits.

In the case of purely precautionary shielding against electromagnetic radiation generally occurring or suspected in the environment, the proportion of conductive threads can be kept relatively low. However, if higher levels of radiation are expected, particularly in the X-ray range, and in particularly hazardous situations, the proportion of conductive threads in the knitted fabric will be higher overall.

The proportion of conductive threads is generally adapted to the requirements.

Silver-coated, untextured threads, in particular silver-coated untextured polyamide 6.6 multifilament threads with a titre of approximately "den70F34/2" can be used as conductive threads.

0 In addition to good electrical conductivity and good skin compatibility, silver also has important antibacterial properties.

In principle, other conductive materials can also be chosen, although the specifics of the individual case must be taken into account.

0 In order to achieve sufficient flexibility of the thread, which may consist solely of conductive material, it can be constructed from a large number of individual wires or filaments, each with only a small individual cross-section.

Within the framework of the given technical and cost specifications, a conductive and skin-friendly thread material suitable for the individual case can be selected.

The "2:2 backed" weave has proven to be particularly advantageous as a knitted weave for the conductive material, as it ensures good durability and the conductive material comes into contact with the skin at as few binding points as possible.

In a "2:2 backed" weave, the conductive thread runs together with one of the basic threads for two stitches and then overlaps two stitches of the basic thread while lying floating.

For the base threads 11, a suitable thread material (titer, number of filaments, degree of crimp) must be selected. Polyamide 6.6 textured dtex 44F34/2 has proven to be suitable here.

A suitable storage feeder is particularly advantageous for compensating for differences in thread tension. This achieves the best results in terms of uniformity of thread tension.

The measures mentioned above can also be used in conjunction with an electrical device incorporated into the knitted fabric 10.
