SATEEN FABRIC CLOTHS Petrus Isbouts, Eindhoven, Netherlands, assignor to N. V. Brabantse Kunstweverij De Huifkar, Eindhoven, Netherlands, aeompany of .the Netherlands Application February 23, 1955, Serial No. 489,979

4 Claims. (Cl. 139-407) This invention relates generally to improvements in sateen fabric cloths and more particularly relates to the production of .a tape of sateen labels in which the warp threads are parallel to the length of the tape; in which the weft threads are transverse to the length .of the tape; a cloth of woven fabric consisting of parallel rows of labels combining the aforementioned two types of tapes; and a tape or cloth of woven fabric wherein differently interwoven threads of marginal portions of the labels all have a weave of the same count.

In weaving, a distinction is made between close and loose weaves. The closest weave is the so-called plain or calico weave, in which each warp thread is disposed alternately above and below a weft thread. This calico weave is shown in Fig. 1 of the drawing, in which the visible parts of the warp threads are indicated in black and the visible parts of the weft threads indicated in white. The loosest weaves are found in sateen fabrics, in which each warp thread passes over a large number of juxtaposed weft threads and then passes beneath a following weft thread or a small number of following weft threads. An 8-stitch sateen fabric is shown in Fig. 2 in which the visible warp threads are again shown in black and the visible weft threads shown in white. By an 8-stitch fabric is understood that the method of interlacing these threads with one and the same weft thread (the so-called repeat) is repeated after eight adjacently disposed warp threads and vice versa.

The long float of the sateen fabric, that is to say the relatively large intervals over which warp threads and the weft threads are disposed loosely one upon the other, enables many threads per unit of surface area to be provided in the material, whereby a closed material is obtained. By this means, the material becomes soft and is given a high gloss. One disadvantage of the sateen fabric is that the threads are disposed in .a very loose manner in the fabric owing to the small number of interlacings, so that cloths made of sateen fabric fray easily. This occurs more particularly at the edges parallel to the weft threads. For example, if sateen labels are formed by these cloths, the said labels must be hemmed before they can be placed in position. This hemming slows up the production of labelled products. Moreover, it is difiicult to provide an exactly straight hem in such a fabric, so the final result often leaves much to be desired.

The invention has for one of its objects .to eliminate, as far as possible, the disadvantage of the loosening of the fibres and to permit'the production of sateen cloths, for example, sateen labels, from long ribbons or long and wide webs of material without these having to be hemmed. The invention consists in that at least one selvedge which is parallel to the weft threads or to the warp threads in a cloth consisting of sateen material is so woven that the weft or warp threads therein alternately or alternating in groups of a few threads, comprise a tight weave, for example, a plain or calico weave, and a loose weave, for example, a sateen weave. In a fabric having such a selvedge, the tight weaveprevents States, Patent 2,808,078 Patented Oct. 1., r 1957 loosening of the fibres, while the sateen weave facilitates the adaptation of the selvedge to the remaining part of the cloth, which has a sateen weave. Aselvedge solely of a tight weave on a cloth with a sateen weave produces a puckering or buckling fabric, since the threads with a tight weave are disposed further apart than with the loose weave of the sateen fabric.

It is possible to prevent the puckering or buckling of the fabric in the selvedge by different groupings of loose and tight weaves. For a fabric in which the number of warp threads and the number of weft threads per square centimetre are inversely proportional 'to the diameters of the threads, it is possible to use a non-fraying selvedge in which not only the threads parallel to the selvedge, but also those which are at right angles thereto, alternately comprise a tight weave and ,a loose weave, or comprise these weaves in alternating groups of a few threads. With cloths of sateen material where this ratio between the numbers of threads and the diameters thereof does not exist, it is advisable for the threads parallel to the selvedge to be woven in such manner that alternately, or alternating in groups of a few threads, they comprise a tight weave and a loose weave, all threads at right angles thereto being given a weave of the same or substantially the same count. By a weave with a specified count is understood a weave in which a thread is disposed once on the upper side and once on the lower side of the fabric per predetermined number of intersecting threads.

A further object of the present invention is to obtain in a sateen fabric between adjacent labels having a sateen weave marginal portions, which have such a tight weave as to enable the manufacture of the labels to weave a tape or a cloth as a whole comprising a great number of labels and to separate the labels from the tape or cloth by cutting without the difliculty that the edges will fray.

Since sateen weave is very loose and frays terribly, when cut, it becomes necessary to fold over the marginal portions of the label. This is a diflicult operation and expensive. It is therefore another object of the present invention to dispense with the necessity of folding over the marginal portions of the labels, so that when the labels are cut from the tape or cloth they are directly ready to be delivered.

As heretofore stated, it is known that tight weave, such as calico weave, does not fray easily, and that it is not possible to weave a tightly woven fabric directly to a loosely woven fabric. The conventional sateen labels are not provided with a calico or tightly woven marginal portion. Since in tight weave or calico weave each weft thread is interlaced with each warp thread, the weft threadhas to pass between the warp threads of each pair of adjacent threads. Consequently the warp threads cannot lie. close together, they are spaced by the interwoven weft threads. This means that in a tight weave there, will be less threads per square inch when the same type and size of yarn is used than in sateen weave, in which many warp threads .or many weft threads lie close together withont any interlacing with or spacing by the crossing threads. If ya tight weave marginal portion is woven directly toa loose weave label the complete label will have a cockling or bulging appearance.

It is, therefore, still another object of the present .invention to prevent the said cockling.

Applicant has found that when the marginal portion is a compromise between a tight weave-and a loose weave, that is, consisting of groups vof threads, each group of which comprises at least one thread being tightly and at least one thread being loosely interwoven with the crossing threads, this marginal portion does not fray when out and it is easily possible to cope with any cockling or bulging tendency of the complete label.

In the drawings:

Fig. 1 illustrates the normal tight or close weave, the so-called plain or calico weave;

Fig. 2 shows an 8-stitch sateen fabric;

Fig. 3 shows the fabric of the anti-fraying marginal portion of a sateen label according to the invention, in which the anti-fraying portion is provided intermediate two successive labels;

Figs. 4 and 5 illustrate anti'fraying marginal portions according to the invention, and in which the differently interwoven threads of the marginal portions all have a weave of the same county Fig. 6 illustrates a portion of a tape of woven fabric having a plurality of sateen labels arranged in successive spaced relations, according to the invention;

Fig. 7 illustrates a portion of a tape of woven fabric having a plurality of sateen labels arranged in spaced relation one next to the other, according to another embodiment of the invention; and

Fig. 8 illustrates a portion of a tape of woven fabric having a plurality of parallel rows of sateen labels arranged in spaced relation according to a further embodiment of the invention.

Referring now more particularly to the invention, Fig. 1 shows a calico weave in which the visible parts of the warp threads are indicated by the letter 12 and the visible parts of the weft threads are indicated by the letter a.

An 8-stitch sateen fabric is shown in Fig. 2 (indicated by the numerals 1-8, inclusive) in which the visible warp threads are indicated by the numerals 1, 3, 5 and 7 and the visible weft threads are indicated by the

numerals

2, 4, 6 and 8. By an 8-stitch fabric is understood that the method of interlacing these threads with one and the same weft thread (the so-called repeat) is repeated after 8 adjacently disposed warp threads and vice-versa.

Fig. 3 shows the fabric of the anti-fraying selvedge according to the invention, which selvedge alternately contains a sateen weave and a plain or calico weave in both the warp direction and the weft direction. This material is particularly suitable for sateen fabrics in which the aforementioned reciprocity exists between the numbers of the warp and weft threads and the diameters of the said threads. The fabric according to Fig. 3 is obtained by a combination of the fabrics according to Figs. 1 and 2. In Fig. 3, the weave of the bottom weft thread is the same as that of the weft thread indicated by 1 in the 8-stitch material according to Fig. 2, while the third, fifth and seventh weft thread correspond to the third, fifth and seventh weft thread, respectively, of this sateen fabric and these sateen-woven weft threads are separated by weft threads, the weave of which corresponds to that of the weft thread a of the calico-weave fabric according to Fig. 1.

For selvedges of sateen cloths, for example, sateen labels in which the aforementioned ratio between the numbers and diameters of the warp and weft threads does not apply, it is possible with advantage to use fabrics according to Figs. 4 and 5.

In Fig. 4 the weaves of the first, third, fifth and seventh weft threads correspond to the weaves of the first, third, fifth and seventh weft threads respectively, of the fabric according to Fig. 2. The second and the sixth weft threads of the fabric according to Fig. 4 are woven in the same manner as the weft thread a of the calico-weave fabric according to Fig. 1 while the fourth and the eighth Weft threads correspond to the weft thread b of the fabric according to Fig. 1. In the fabric according to Fig. 4 therefore, the weft threads alternately show a sateen weave or interlacing and a calico weave or interlacing. On the other hand, the warp threads have a 4-stitch interlacing, in which1one warp thread appears once on the upper side and once on the underside of the fabric in every four successive warp threads.

In the fabric according to Fig. 5 t e first, third and fifteenth weft threads are woven in the same manner as the first, second eighth weft threads respectively, of the fabric according to Fig. 2 While the even num bered weft threads correspond alternately to the weft threads a and b of the fabric according to Fig. 1. Therefore, in this case as well, the weft threads are alternately given a sateen weave and a plain or calico weave, while the warp threads all show a 4-stitch interlacing.

Because the warp threads in the fabrics according to Figs. 4 and 5 are all shortened to the same extent by the Weave, the puckering or buckling of the fabric is completely prevented.

it is possible according to the invention to use many other combinations of tight or loose weaves apart from those shown in the drawing. For example, instead of individual threads, it is also possible for groups of two or more threads to be alternately interlaced by a sateen weave and a calico weave. Other methods of weaving are also possible, the main feature being that the provision of a selvedge with a combined weave or interlacing wholly or substantially eliminates the fraying and the puckering or buckling.

Sateen labels are generally woven in a long ribbon in which the labels are disposed one after the other, or in a web in which the labels are woven alongside one another as well as behind one another. According to the invention, with a ribbon of labels which already have a selvedge on the edges parallel to the warp threads, it is also possible for transverse selvedges to be woven between the labels, in which selvedges the weft threads alternately, or alternately in groups of a few threads, have a tight weave and a loose weave. After a ribbon of this type has been woven, the labels may then be separated from one another by the transverse selvedges being cut in the direction of a weftthread. If the labels are disposed both behind and alongside one another in a web, then it is possible according to the invention for longitudinal selvedges to be woven between the labels in addition to the transverse selvedges as in the ribbon just referred to the warp threads of said longitudinal selvedges alternately, or alternately in groups of a few threads, forming a tight weave or interlacing and a loose weave or interlacing with the weft threads. After the said web has been woven, these longitudinal selvedges may also be cut in the direction of the warp.

Fig. 6 is a portion of a tape of woven fabric in which a plurality of sateen labels are arranged in successive space relation, the warp threads extending lengthwise andthe weft threads extending transverse the length of the tape and portions extending throughout the entire breadth of the tape and being provided intermediate adjacent labels, said portions consisting of a plurality of groups of weft threads, each group comprising at least one weft thread being tightly and at least one weft thread being loosely interwoven with the warp threads.

Fig. 7 is a portion of a tape of woven fabric in which a plurality of sateen labels are arranged in space relation one next to the other, the weft threads extending lengthwise and the warp threads extending transverse the length of the tape and portions extending parallel to the warp threads and being provided intermediate adjacent labels, said portions consisting of a plurality of groups of warp threads, each group comprising at least one warp thread being tightly and at least one warp thread being loosely interwoven with the weftthreads.

Fig. 8 is a portion of a cloth of woven fabric in which a plurality of parallel rows of sateen labels arranged in space relation, the warp threads extending lengthwise and the weft threads extending transverse the length of the cloth, portions extending throughout the entire breadth of the cloth parallel to the weft threads and portions extending throughout the entire length of the cloth parallel to the warp threads, both types of portions being provided intermediate adjacent labels, the first portions consisting of a plurality of groups of weft threads, each group comprising at least one weft thread being tightly and at least one weft thread being loosely interwoven with the warp threads and the second portions consisting of a plurality of groups of Warp threads, each group comprising at least one warp thread being tightly and at least one warp thread being loosely interwoven with the weft threads.
