Description
SPECIFICATION
A web of fabric made up of textured satellite yarn
The present invention relates to a web of fabric made up of multifilament threads which, in turn, consist of substantially divided m ulticomponent fibres of the matrix segment type, having welded points at regular intervals each completely or partially catching the cross-sections of each individual multifilament thread.
Threads made up of individual filaments of the multicomponent matrix segment type are described for example, in German
Offenlegungsschriften Nos. 2803 136 and 28 09 346 and, in this respect, relate to this disclosure. They consist of at least two different polymers with clearly differing shrinkage behaviour. The components can be completely or partially separated by the release of the differing shrinkage.
It has now been found that, under certain conditions, surprising effects can be produced by the false twist texturing of threads of the type described if the processed polymers and the texturing conditions are.correctly chosen. The threads of the type described which are treated by false twist texturing are eminently suitable, for example, for processing into textile cloth, novei and unusual effects being exhibited in the appearance, feel and wear behaviour particularly after processing into woven fabrics.
An object of the present invention is accordingly to prepare a web of fabric composed of false twist textured threads with individual filaments of the multicomponent matrix segment type, which in the finished state has as excellent novel feel, a good appearance and excellent properties in wear.
According to the present invention there is provided a web of fabric composed of multifilament threads which comprise substantially divided multicomponent fibres of the matrix segment type having welded points completely or partially catching the cross-sections of each individual multifilament thread at irregular intervals, wherein the warp and weft of the fabric are made up of threads having substantially the same appearance which each have a thickness of from approximately 35dtex to 1 20dtex and individual filaments of the segment content each of from four to eight times 0.2 to 1 .2dtex, the individual multifilament threads having in the range of from approximately 3 to 80 welded knots which completely or partially catch the crosssection of the respective individual multifilament thread.
The multifilament individual threads used similarly for the warp and the weft advantageously have a thickness of from approximately 40 to 80dtex the individual filaments being filaments of the matrix segment type divided into their matrix and segment components, which have six segments separated by a star-shaped matrix prior to division, the area ratio in the undivided crosssection of the individual filament being from about 1 5 85 to about 45 : 55 for matrix to segment content and the individual thickness of the segment components present between the welded knots lying in the region of from about 0.35 to about 1.1 dtex. The number of welded knots which the individual multifilament threads have, can advantageously lie in the range of from about 10 to about 75 per metre in the finished cloth.
A particularly advantageous embodiment of the invention is a web of fabric of the type described in which the threads processed into the warp and weft consist of individual filaments of the matrix segment type containing 20% of polyamide 6 as matrix and the respective total of 80% of polyethylene terephthalate as segment content, split into six individual segments which are separated from each other by the six-pointed starshaped matrix, the individual thickness of the multifilament threads is dtex 50f 15 and in that the warp has from 30 to 68 threads per cm and the weft from 30 to 44 threads per cm, the density of the succession of welded knots in the finished cloth is from about 5 to 75 knots per metre respectively in the warp threads and the weft threads. The textile fabric is preferably made up in plain weave.In this case, the thread sensity can be from about 30 to 48 threads per cm in the warp and from about 28 to 46 threads per cm in the weft.
Another advantageous textile web of fabric according to the invention has multifilament individual threads of the matrix segment type in the warp and weft, the thickness of the multifilament threads at any time being 76dtex with 20 to 24 individual filaments of the matrix segment type and the thread density in the fabric being from about 28 to 50 threads per cm for the warp and from about 25 to 40 threads per cm for the weft.
Other advantageous combinations include constructions in which threads of the type described above having a thickness of dtex 50f 1 5 for the warp and with a thickness of dtex 76 with 20 to 24 individual filaments for the weft have been used, and in which a thread density of from about 30 to 68 threads per cm in the warp and from about 25 to 40 threads per cm in the weft has proven advantageous. A construction in which threads composed of filaments of the matrix segment type having a thickness of 76dtex with 20 to 24 individual filaments are used in the warp and threads of from about 100 to 11 Odtex in the weft at thread densities of from-about 28 to 50 threads per cm for the warp and from about 22 to 35 threads per cm for the weft has also proven advantageous.In this case, the multifilament individual threads having a thickness of 50dtex made up of 1 5 individual filaments of the matrix segment type can also be replaced, for example, by those made up of from 12 to 20 individual filaments of the matrix segment type.
It has been found that the properties of the finished web of fabric according to the invention are determined essentially by the individual thickness of the individual segment contents and the density, distribution and structure of the welded knots which catch and connect the individual filaments of the matrix segment type, which would otherwise have divided constituents, in the thread assembly over the entire thread cross-section or part of the cross-section respectively. Thus, the individual thread assembly is also essentially held in the finished cloth can advantageously be altered to a great extent by selection of the number of welding knots, and it has been found that the web of fabric according to the invention has a feel very similar to that of silk, particularly in the form which is described as being particularly advantageous.
The number of welding knots occurring during the texturing treatment and remaining in the finished cloth is greatly dependent upon the fixing temperature applied during the texturing process and the residence time on the fixing apparatus as well as on the material used for making up a matrix segment filament. Temperatures of in the range of from about 21 20C to 2250C have been found to be advantageous when using nylon 6 as matrix material and polyethylene terephthalate as segment material, fixing temperatures in the range of from about 214 to 2250C being important, in particular, for processing on fast-operating weaving machines.
Treatment of the cloth with a solvent which reduces the zero shrinkage temperatures of the segment polymer or polymers by at least 1000C and which is preferably methylene chloride, following the production of the textile web of material also plays an important part. The division process of the matrix segment individual filament which begins during the texturing of the individual threads is completed during this treatment.
Moreover, a proportion of the knots which are present during the processing and which simplify the processing due to the thread end obtained and make the sizing or other treatment for obtaining a thread end superfluous, is opened again to achieve adjustment of the advantageous feel and the advantageous features of appearance and wear.
Embodiments of the present invention will be described by way of example with reference to the accompanying drawings figures obtained from photographs produced by a scanning electron microscope and which show an example of the fabric according to the invention before and after treatment with a solvent, for example, methylene chloride.
Figure 1 shows a fabric according to the invention on a scale of 50 :1 before treatment with the solvent; and
Figure 2 shows the same fabric on a scale of
100 :1 also before treatment with the solvent;
Figure 3 shows the same fabric according to the invention on a scale of 50 :1; and Figure 4 shows the same fabric on a scale of
100 1, but after treatment with the solvent.
