Abstract

A knitted garment, in which at least one stitch row consisting of two fibres of different types is made, possesses, at least in the case of alternating stitch rows, a stitch row which is made from a synthetic filament yarn (continuous thread), combined with a finished yarn (spun yarn) consisting of a cellulose fibre. The cellulose fibre arranged on the inner surface of the garment possesses, in the raw state, a water retention of at least 80% and a natural crimping which results from the cross-sectional asymmetry therein.

Description

description

The invention relates to knitted or crocheted clothing (hereinafter for the sake of simplicity always referred to as "knitted clothing"), especially underwear (Underwear) such as pantyhose and the like, and a method of manufacturing this knitwear.

Such garments are currently being used for reasons of practicality, Strength, elasticity and the like. Made from synthetic materials that can be regarded as practically hydrophobic, such as in particular filament yarns (Continuous filaments) with polyamide structure, available under the trademark nylon in its various Shapes are known (nylon 6, nylon 66, nylon 11). For high quality clothing an elastane filament yarn is used in it, a fiber that comes under the trademark Lycra is known. Garments of this type, however, generally offer at Do not wear adequate comfort, especially when in close contact with worn on the wearer's skin, and in the place where it is even tighter Come into contact with it, as with the so-called panties in the case of tights or Briefs. The problem you have faced so far has been with these garments to make it more comfortable for the wearer and especially see below for wearing without To make use of a panty suitable; for this problem so far, however no completely satisfactory solution can be found.

It has already been suggested, especially for socks, hydrophobic, hydrophilic and elastic yarns by using special knitting types (meshes) during the knitting or. To incorporate the active process. However, this solution is in unsuitable for the forms in which it has hitherto been proposed and implemented for items of clothing, e.g.

Mainly tights that can cause serious problems In terms of the low weight, the transparency, the good fitting properties (den good fit) and other features that are essential for such garments.

It has now been found that the problem of making clothes or garments of the above type and in particular tights, which are light, precisely fitting, transparent and absolutely comfortable, is solved by that at least part of the clothing or items of clothing in alternating rows of stitches a course of stitches made from a synthetic filament yarn (continuous thread), combined with a finished yarn (spun yarn) made of cellulose fiber, which in their Coarse state a water retention of at least 80%, preferably within the Range from 80 to 95% (determined according to ASTM standard D-2402-69) and one has natural ripple resulting from a cross-sectional asymmetry, this fiber being located on the inner surface of the garment.

It should be noted that compared to those already proposed natural cellulose fibers the retention and absorption reach values which are almost twice as high.

The asymmetry of the cross-section and the curling associated with it are then obtained using known spinning techniques. Appropriate procedures are particularly disclosed in U.S. Patents 2,428,046 and 2,572,936 and in United Kingdom 595,403 and in the article by F.F. Morehead and W.A. Sisson "Skin effect in viscose rayon "in" Textile Research J 15, 443-450 (1945), as well as in the Article by W.A. Sisson and F.F. Morehead "The skin effect in crimp rayon" in "Textile Research J. "23, 152-157 (1953).

This curled fiber preferably has good elastic properties on; therefore, a modal regenerated cellulose fiber which conforms to the ISO standard is preferred 2076-1977, but known as fiber sold under the trademark "PRIMA" in is brought to trade, is ruffled.

With the above two combined yarns (nylon filament and spun cellulose yarn) an elastane fiber can be used for high-quality clothing, such as Lycra, this combination using conventional Procedure can be achieved.

The manufacture of the clothing or items of clothing according to the invention does not lead to any special difficulties and no methods are required those about the skills of a knitting or warp knitting expert.

Below are some examples of the preparation of the invention Clothing or items of clothing indicated, although they were also using conventional methods Method can (can) be knitted or crocheted using circular knitting machines with multiple feed, whereby care must be taken that the cellulose fiber, which has a high level of water retention and absorption on the inside of the slip portion comes to rest while the synthetic filament yarn, especially nylon, on the outside of the same, possibly combined with the elastomeric filament yarn> come to lie.

The invention is described below with reference to tights and the panty part of the same explained in more detail, but it should be noted that it is by no means limited to this, but also applies to others comparable Clothing or garments extends in which the same requirements are met and the same benefits are desired.

The invention is described below in particular with reference to accompanying drawings and those specified below, which do not limit the invention Examples explained in more detail. The accompanying drawings show: FIG. 1 in schematic form Form the layer of common synthetic filament yarns (continuous threads) in a knitted one respectively. knitted fabric, i.e. in one in which the panty part is made, without introducing the spun which is provided in combination therewith according to the invention Cellulose yarn; Fig. 2 is a cross-sectional view, also in schematic form of the knitted or Knitted fabric stitches with respect to the first feed (Feeding) a conventional circular knitting machine; Fig. 3 in a similar representation as in Fig. 2, the manufacture of the fabric meshes or loops in relation to the second feed (loading) of a conventional circular knitting machine, with additional in addition to the usual synthetic filament yarn (continuous thread) also the spun cellulose yarn is used, so that one arrives at the garment according to the invention; and FIG. 4 shows, in a form similar to that in FIG. 1, a knitting or

Acting according to the invention, in which the usual synthetic filament yarn is combined to produce the pant part. with the spun cellulose yarn, the latter on the side in contact with the wearer's body come to lie.

In the examples described below, reference is made to the above Referred to the illustrated drawing.

Example 1 For the manufacture of tights, the panty part of which is only contains a conventional synthetic filament yarn, and for the production of the invention Tights that combine both a common synthetic filament yarn as well as a special spun cellulose yarn becomes a conventional one Circular knitting machine, especially one with two feeds (feeds), used.

The traditional panties, as shown in Fig. 1, are made by inserting a textured polyamide filament yarn into 1 in the first feed and at 2 in the second feed. The textured polyamide filament yarn, which is the same for both feeds, for example a 40 denier (44 dtex) yarn.

Fig. 2 shows a cross-sectional view of the needles formed from a Yarn 1 and a yarn 2 form existing rows of knitting stitches for the production of the traditional panty part of Fig. 1.

To introduce a spun cellulose yarn, especially one spun yarn (finished yarn) which in its c ob state has water retention of at least 80%, preferably within the range of 80 to 95% (determined according to ASTM standard D-2402-69, namely by immersion in water of 200C and dewatering in a centrifuge with an acceleration of 1000xg)>, enough it according to FIG. 3 that this yarn, indicated by the number 3 in FIG. 3, in which it is shown in dashed lines, along with a textured one Polyamide filament yarn through the same feed, for example the second feed, is introduced. The only precaution known per se that was taken is to use the traditional thread guide with a single hole, through which the "introduced material" is usually passed through an insertion finger with two holes, namely one for the polyamide filament yarn and the other for the special cellulose spun yarn.

The mutual position of the two holes and the slope of the Yarn guides influence the amount of yarn introduced and thus determine on which side of the fabric the special spun cellulose yarn comes to lie on (i.e. either on the inside or on the outside of the panty part). Of the Those skilled in the art are used to the positions of the yarns on a diagram (taken along the needles) as indicated in FIG. 3.

Fig. 4 shows the situation when introducing a spun Cellulose yarn of the type indicated above in combination with the usual polyamide filament yarn in a feed and in the introduction of a polyamide filament yarn alone in the other feed is received.

In Fig. 4, the reference numerals 1 and 2 designate again usual Polyamide filament yarns, while reference number 3 denotes the spun cellulose yarn of the specific type mentioned above. This spun cellulose yarn has preferably a titer within the range from 15 to 10 tex (corresponds to Ne 40'S and 60'S). Instead of polyamide yarns, other synthetic yarns, such as polyester yarns can be used.

Example 2 According to the invention it is also possible to use panties in tights of the restraint type. A solution similar to that in dem'above Example 1 described are applied: In the conventional Restraint-type panty part, a strong elastic effect is achieved by introducing it of a textured polyamide yarn (generally of the dtex 44 / F.T. type) through a Feed and an elastic yarn, for example the one under the designation Known type of elastane (which generally has a titre of 78 dtex)> by the other feeder. According to the invention, in accordance with Example 2 the cellulose spun yarn of the above type with the polyamide filament yarn combined, which, as stated above, forms part of the layer of the restraint panty.

Example 3 One works as in the previous examples, also then if knitting machines or warp knitting machines with 4 or more feeds are used. It will be the same Get results whenever the polyamide filament yarn - in alternating feeds - with the spun Cellulose yarn of the type indicated above is combined.

From the above description in conjunction with the illustration the accompanying drawing shows the advantages of a garment with the structure according to the invention clearly emerges. Regardless of whether it is Tights or a differently knitted or crocheted undergarment, such as T-shirts, stockings (socks) or the like, is supported by the present invention a significant improvement in terms of the transpiration properties and the hygienic properties achieved.
