Textile Based on a Mixture of Abrasion Resistant Technical Fibers

Abstract

The invention concerns a single-layer fabric comprising two yarns, a so-called comfort cellulosic material yarn and a technical yarn with high abrasion and temperature resistance properties, said two yarns being woven or knitted so as to define at least two separate portions in the thickness of the fabric, a first outside portion, with a majority of technical yarn, and a second inside portion, with a majority of comfort yarn, said portions being at least partly entangled. The invention is characterized in that the technical yarn, produced from continuous filaments, whereof the web is coated over at least 75% of its surface with a coating comprising at least partly natural fibers.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a textile based on an abrasion-resistant mixture of cellulose fibers, for example cotton fibers, and technical fibers. [0002] More particularly, the subject matter of the invention is a fabric with the appearance of jeans or more generally having the appearance of cotton cloth which is intended for the manufacture of pants, jackets, including bomber jackets, gloves, and the like. DESCRIPTION OF THE PRIOR ART [0003] Fabrics having qualities during abrasive impacts, for example the impacts experienced by the clothing of a motorcyclist when he falls off, are known in the prior art. These fabrics generally require a minimum of two separate layers: either a comfort lining is positioned, to make it possible to wear next to the skin, or a coating of products with a low coefficient of friction (silicone, polytetrafluoroethylene (PTFE), and the like) is produced on a resistant material (mesh or fabric made of aramids, and th...

Benefits of technology

[0009] Thus, the main aim of the present invention is to provide a fabric which makes it possible to reduce the difference in performances between technical textiles and textiles intended for clothing. More specifically, the aim of the invention is to provide a fabric which makes it possible to solve the technical problems of the fabrics known in the prior art and thus has excellent mechanical properties, in particular of resistance to fire, to high temperatures and to abrasion, which makes possible a hold of the colorants which are applied thereto at a level at least equal to that possessed by fabrics made of natural material, for example cellulose (cotton or flax in particular), and which are as comfortable to wear as these fabrics.

[0012] This fabric has excellent mechanical qualities and textile qualities (in terms of ease of weaving, on the one hand, and of comfort, on the other hand) and it is intended in particular for motorcyclists or users of skateboards, roller skates, bicycles or snowboards, providing them with protection, comfort and a stylish appearance.

[0013] Due to its monolayer design, it is intended for the manufacture of light clothing which can be worn next to the skin and which offers excellent protection from abrasion in the event of falls. Protection is provided by the extreme resistance to abrasion of the technical yarn, which is present predominantly in the outer portion of the fabric.

[0025] It is thus noted that the textiles obtained according to the invention, although they make it possible to retain the external appearance of a 100% cotton fabric, demonstrate much better performances than those of the 100% cotton fabrics of jeans type and, in some cases, performances virtually identical to those obtained with leathers used competitively by the Fédération Française de Motocyclisme.

[0026] The comfort arises from a special construction of “warp effect” type; the warp effect can be obtained by the counts of the yarns employed (for example, thicker in warp than in weft) or else by the weave itself (satins, twills, half plaits, and the like), making it possible to combine the above qualities with a single layer of fabric which protects by virtue of its outer surface and is worn next to the skin by virtue of its hydrophilic inner surface. This fabric also has high-level thermal qualities.

Problems solved by technology

However, the latter solution exhibits two major disadvantages: the discomfort due to the lack of breathability of the complex because of the coating and the “industrial” appearance given by the coating.

In addition, these are fabrics which allow only slight aeration in summer and thus they are rather unpleasant to wear during this season.

The great majority of the other alternatives known in the prior art are polyamides which melt at a temperature of less than 250° C. Moreover, the latter are not self-extinguishing, which represents an obvious additional danger for the wearer of clothing produced with such textiles.

This is because, during an abrasive impact, for example on a motorbike, such materials can rapidly locally reach their melting point and are then in direct contact with the skin of the user, then bringing about lesions and burns which are difficult to treat (the risk of complications is increased in the event of fire).

Polyesters have a degree of resistance to abrasion but do not have satisfactory fire-resistant qualities.

Polyethylene has very good mechanical qualities but its melting point lies in the vicinity of 120° C. Only para- and meta-aramids have mechanical and fire-resistant qualities but their performances deteriorate in the presence of UV radiation.

Ceramics might combine these qualities but their cost is still too high to allow economically viable industrial operation.

In any case, none of these materials has satisfactory textile qualities; they are difficult to dye and have an unpleasant feel for the wearer of the clothing, which corresponds to the feeling of contact of plastic with the skin.

Respective disadvantages exist in each of these cases, in particular in summer (discomfort, lack of breathability and of hydrophilicity, poor appearance, and the like).

The technical yarn thus obtained is only very partially covered at the surface and the part of this yarn made of synthetic material is highly exposed, which does not make it possible to overcome the disadvantages of the textiles based on artificial yarns described above, in particular with regard to the visual appearance and the comfort.

In addition, such a technical yarn does not make it possible to color the fabric obtained as either the colorants are very poorly retained by the synthetic materials used for the technical fibers or use is made of polyester and polyamide, which dye well but for which the feel and the gloss present problems with regard to the look of the fabric obtained and with regard to the technical performances, which are poorer.
