Method for manufacturing textile products and textile product thus manufactured

Description

[0001] The present invention relates to a method for manufacturing textile products and to the textile product thus manufactured.

[0002] It has long been known to use textile products known as non-woven fabrics, manufactured with systems other than those that interweave the threads by weaving or forming knitting. These non-woven fabrics are substantially constituted by a textile foundation made of fibers or threads which are bonded by means of suitable bonding means, particularly of the chemical type.

[0003] The simplest methods for bonding non-woven fabrics entail impregnating the textile foundation with suitable adhesives, such as latexes of synthetic rubber or acrylic derivatives and the like. Non-woven fabrics are also known constituted by threads which are chemically bonded by hot pressing with powdered binders or with thermoplastic fiber binders.

[0004] The use of thermoplastic fibers, which melt and bind under the influence of the heat, allows in particular to obtain non-woven fabrics composed of a single kind of fiber, for example polyester fibers.

[0005] The items manufactured in this manner are generally rather finely meshed, have a paperlike appearance and are at the same time tough and durable.

[0006] The above-mentioned rigidity and aesthetic characteristics have caused said non-woven fabrics to be used preferably to produce various kinds of padding, for example to strengthen materials in the automotive field.

[0007] Viceversa, the non-woven fabrics have not been used up to now in the clothing field, owing to their rigidity and to their limited resistance to sewing and tearing. The non-woven fabrics are furthermore generally offered in a single color, namely white, without the possibility of dyeing them in the chosen color.

[0008] The aim of the present invention is to solve the above problem, by providing a method for manufacturing textile products of the non-woven fabric type which are soft and sewing- and tear-resistant, so as to allow to use them in the clothing field.

[0009] Within the scope of this aim, an object of the present invention is to provide a textile product which is simple to manufacture and versatile in use, particularly allowing a coloring which is suitable for the intended use.

[0010] This aim, this object and others which will become apparent hereinafter are achieved by a method for manufacturing textile products according to the present invention, characterized in that it entails preparing a textile foundation of non-woven fabric made of thermoplastic fibers; impregnating said textile foundation of non-woven fabric with a spreading of polyurethane; dyeing the resulting product; and finally subjecting the product to a softening wash.

[0011] Further characteristics and advantages of the method according to the present invention will become apparent from the following detailed description of a preferred embodiment of the textile products according to the invention.

[0012] The method for manufacturing said textile products entails first of all preparing a textile foundation made of non-woven fabric formed with thermoplastic fibers, particularly constituted by polyester fibers.

[0013] It should be noted that the textile foundation has a paperlike appearance which resembles in particular parchment and vellum.

[0014] The textile foundation made of non-woven fabric is then impregnated with a slight spreading of polyurethane suitable to assuredly give the product stability and resistance to sewing and tearing.

[0015] The resulting product is preferably constituted by 48% polyester fibers and 52% polyurethane.

[0016] The resulting product is then subjected to a dyeing step in order to obtain the intended color without however concealing the pattern formed by the loose fibers on the surface of the non-woven fabric.

[0017] In order to apply the color it is possible to provide a low-temperature dyeing in the piece, which is suitable to provide a fabric having an uneven color distribution.

[0018] As an alternative, it is possible to provide a so-called "star" dyeing in the fabric which is suitable to give the fabric an opalescent appearance.

[0019] It is also possible to impregnate the fibers with dyed transparent polyurethane, which is suitable to give the material a more uniform appearance without hiding the basic pattern of the textile foundation of non-woven fabric.

[0020] The choice of the dyeing method used clearly depends on the characteristics to be given to the textile product for the intended uses.

[0021] Finally, the textile product is subjected to washing in the piece, which is suitable to give the fabric a suitable softness for use in the clothing field.

[0022] This softening wash is performed in water at the temperature of 30^oC with a pH of 8.

[0023] The described method therefore allows to provide textile products of the non-woven fabric type which have high resistance to sewing and tearing, particularly such as to allow their use in the clothing field.

[0024] The fact should be stressed that the spreading of polyurethane, in addition to providing the required strength, ensures perfect protection against weather such as rain and wind.

[0025] The textile products thus obtained furthermore have the chosen coloring and have a softness which allows them to provide optimum fit in the clothing field.

[0026] In the practical execution of the invention, the shape and the dimensions may be any according to requirements.
