The invention relates to a method for producing stretchable and contractible hosiery made of synthetic, multi-ply yarns that are twisted in one direction, heat-set and for the purpose of Generation of a permanent twist tension are turned up in the opposite direction and which are in alternating rows of stitches with S and Z twist are forfeited.

Such hosiery is intended to conform to a wide variety of different leg sizes and preferably also adapt to different foot sizes, but still be very soft, firm and durable. Important is also that such hosiery is highly translucent. Made of elastic, single-thread yarn Manufactured stockings largely leave the desired softness, strength and durability miss, especially if they are made in a known manner from single threads of 15 den with 16 to 20 twists per centimeter to produce a transparent, elastic stocking. Used if synthetic, multi-thread yarns were used to produce hosiery, this was limited so far on the use of those with less than 40 twists per centimeter or with one Total denier of well over 20. To forfeit such yarns with a lively S and Z twist To be able to do so, they had to be glued, stretched or opposite to their direction of rotation by one Coil withdrawn or plied forfeited with an oppositely twisted or untwisted thread will.

The object of the invention is now to produce stretchable and contractable hosiery synthetic multifilament yarns that do not require these additional measures when knitting.

The invention solves this problem in that now multi-thread, from two to four individual threads existing yarns of 15 the total denier and 40 to 60 twists per centimeter in the living state Twist will be forfeited.

In a multi-thread yarn of 15 denier, the individual threads form individual threads when turned Loops, so that with a twist of 40 to 60 turns per centimeter, these loops interlock with one another confuse so much that the yarn, contrary to the previous view, is still without the aforementioned additional measures of gluing, shedding, etc. can be forfeited. With single thread 15 den yarn, on the other hand, is simply looped and in the case of multi-threaded yarn with a high denier, the bulk of the yarn increases its stability and / or its workability.

In this way, stockings are obtained which can be stretched by 20 to 275% or more of their length and then return to their original state. You can use the leg section in this way and manufacture the foot part with the exception of the heel and toe parts of stockings, all of which have been known so far Exceeding expectations placed on elastic, wafer-thin stockings.

The single threads used for each of the yarns should not be stronger than 5 den and in each yarn be about the same.

As already said, the heel and toe part of the hosiery preferably does not consist of the according to the invention used high-twisted yarns, but z. B. from a yarn with the same Titer and the same number of single threads, but with a much lower twist.

The yarn used for the double edge of the stocking can be used in any conventional manner Achieving reinforcement expediently be made from a yarn with several individual threads.
