Abstract

Highly elastic hosiery is made from synthetic, multicapiallary textured threads in alternating rows of S and Z turns. The fineness of the worked-in threads amounts to 2 tex and these each consist of two equally strong separate threads. The number of turns/m is 3500, and the hosiery can be stretched to some 500% of its original length in its dyed, unfixed state.

Description

The invention relates to highly elastic hosiery of synthetic, multi-capillary, false twist-shaped yarns in a series of alternating S- and Z-twists.

Known high-elastic hosiery made of shaped, permanently crimped, elastic yarns with three to seven elementary fibers and an overall fineness of about

Although the 2.2 tex exhibits high elasticity, it has considerably greater hiding power and hence less translucency compared to delicate ladies' stockings of inelastic synthetic monofilament yarns of the same thickness.

Also elastic ladies tights are known whose synthetic curly yarns, composed of two to four elementary fibers, have a total fineness of 1.7 tex and a ductility of 4,000 to 6,000 per meter.

This hosiery has improved translucence over such hosiery of three to seven capillary yarns with a total fineness of 2.2 tex, but does not have sufficient usability due to the higher overall fineness.

Hosiery, manufactured according to DE-AS No. 1,273,111, however, achieves only a limited elasticity of about 275 ° / o. In order to achieve higher elasticity, it is used here at a finer chosen one titer of a large number of twists, which β leads to an increasing frequency of breaks due to the increasing axial twist of the yarn, thus setting limits for increasing the number of twists and hence for possible elasticity.

Known fine stockings of inflexible synthetic monofilament yarns with a fineness of 2.2 or 1.7 tex show translucence and elegance, but do not have elastic properties, which has proven to be disadvantageous in wearing and fit.

The purpose of the invention is to provide a highly elastic hosiery which, on the one hand, exhibits, in respect of durability and translucency, the properties of an inflexible ladies' stocking of equally fine synthetic monofilament yarn; has the benefits of a highly elastic stocking in terms of fit and feel when worn.

SUMMARY OF THE INVENTION It is an object of the present invention to produce translucent, high-elastic hosiery which exhibits high elasticity and the best wear and wear properties as well as the highest translucency and elegance using a flexible synthetic yarn shaped in a known manner by false twist.

The problem is solved by the highly elastic hosiery according to the invention, which consists in the fact that the yarns met have a fineness of 2.0 tex, are composed of two equally thick elementary fibers and formed by a number of 3200 twists per meter.

The highly elastic hosiery has a length corresponding to 20 [deg.] / Maximum stretch length in the dyed state in a direction perpendicular to the posts and is unstable.

The fineness of 1.0 tex of the elementary threads of the yarns according to the invention is above the fineness of 0.8 and 0.8, respectively. 0.83 tex of elementary yarn fibers with a fineness of 2.2 tex (3) and / or 1.7 tex (2).

These synthetic yarns of larger diameter elementary fibers, shaped by about 3,200 twists per meter, with an unusual overall fineness in themselves, have an improved crimping capability due to the more favorable ratio between single fiber thickness and total yarn.

Better ratio to mesh size, resp. The length of the yarn per loop, created by the unusual thickness of the yarn itself, reduces the extraordinary mutual extension of the elementary fibers between itself and the yarn in the stitch bond, thereby giving the hosiery an extremely high recovery ability so that of an initial length equal to about 20% of the elongated length. As a result, the hosiery produced according to the invention adapts better to the shape of the body than at the usual yarn thicknesses and prevents unwanted formation of creases for the clamping and instep of the foot. The usability of the hosiery according to the invention improves as a result of the increased durability and exceeds substantially the average values of goods of a comparable kind.

In the stretched state, i.e. on the leg, the hosiery is extremely translucent and achieves, in its representative quality, the values of the monofilament hosiery with greater dullness and elegance due to the structural phenomenon achieved on the yarns.

The invention will now be described in more detail by way of example.

The hosiery according to the invention relates to both stockings and hosiery and is manufactured on a conventional small diameter circular knitting machine according to generally known methods, respectively. in hosiery also according to the ready-to-wear method, wherein the knitted fabric is made from a yarn with a total fineness of 2.0 tex from two equally thick elemental fibers with a fineness of 1.0 tex, shaped according to the well-known false twist method.

In order to achieve a high yarn curling ability and to obtain high hosiery elasticity, it is advantageous for the yarn to obtain about 3 200 twists per meter in the forming process and when the yarn, each having one S- and one Z-twist, entangles in the loops of the yarn. alternating in rows on a knitting machine.

Hosiery now exhibiting a high degree of elasticity is dyeed flat in suitable containers to prevent uneven curling of the overall stitch bond, but improves after recovery, drawing, neither fixation nor shaping, and exhibits only about 20% in this state. % of the length it has in its stretched state, i.e. in use.
