DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
The present invention relates to a knitted sweater or a corresponding garment article, and to a method of manufacturing such a knitwear article.
SUMMARY OF THE INVENTION
A special feature of this article is that it is knitted of a special yarn, viz. preferably indigo dyed cotton yarn, that is the same type of yarn as used in the so-called cowboy or denim cloth, known for being extraordinarily wear resistant, though not particularly soft. The yarn is rather difficult to use in knitting machines, but it may be used, after all, and the product is a knitwear which is softer that the woven fabric and thus well suited for knitted sweaters and the like, which will then similarly be highly wear resistant.
Certain parts of the garment, viz. the collar and the so-called button-bands, i.e. the vertical front side parts in which there is mounted cooperating snap fasteners or provided buttons and button holes, respectively, may advantageously, both stylewise and functionally, be made of the said woven and more rigid denim/jeans fabric. The invention relates to this particular combination, i.e. to a knitwear article having a collar of a rigid character and optionally having button-bands well suited as a mounting base for closure means, all with a harmonic fabric selection with consistent use of extra wear resistant and almost unlimited washable materials.
However, there is a problem in that the knitted fabric will shrink in washing more that the woven fabric, whereby there is a pronounced risk of a forthcoming formation of folds along the woven fabric pieces. It is known that this type of improvement can be made in arranging for the more rigid parts to be stretched by the stitching together with the other parts, just as during the stitching work it is possible to compress the less rigid fabric, but such a technique is unsuitable when, as here, relatively marked differences are in question.
With the invention it is a basic condition that an already indigo dyed cotton yarn is made into fully-fashioned knitwear pieces in flat knitting machinery, and that these pieces are subsequently sewn together for forming the desired knitwear articles. According to the present invention the fully-fashioned knitwear pieces as produced by the flat knitting are made of a relatively loose knitting with a pronounced oversize amounting to some 20-40% and preferably 30-35%, whereafter these pieces are subjected to a washing treatment with a following accelerated drying, preferably by washing in bundles with a subsequent tumbler drying, whereafter the fabric pieces are sewn together, partly with each other and partly with one or more of the said woven fabric parts for the formation of the final product. By this method the knitwear pieces will shrink to suitable sizes and to a suitable rigidity of the knitting, and it is a resulting consequence that the woven fabric pieces can now be stitched on with a minimum of attention and without any special stretching requirements. The knitted fabric pieces will be practically ready-shrunk and `condensed`, such that later on the woven pieces will not get wrinkled. In departing from a pronounced loose knitting the fabric pieces may be so widely deformed that a possible rest shrinkage later on will correspond to a modest shrinking of the woven fabric, and the conditions may be so adapted that the two types of fabric will behave uniformly.
As products, knitwear articles according to the invention are characteristic in that as fresh from the factory products they appear with sewn together, fully-fashioned knitwear pieces assuming a state in which, as a result of a previous washing treatment, they are condensed so as to have a low residual shrinkability also in the areas where the said woven fabric pieces are sewn on, whereby the joining areas can be smooth.
