Definitions
- the present invention relates to an improved method for make a new type of stretch fabric both in the warp direction and in the weft direction, and more particularly a fabric usable as coverings for seats, especially automobile seats.
- the complex shape that the seat and the seat back can have to improve the comfort and support of the driver's body do what we do more and more use of extensible textile structures to realize such coatings.
- the first which makes it possible to obtain articles which can have a very high stretch, up to 40%, involves making the fabric from wrapped, assembled or equivalent yarn, the core of which consists of a thread belonging to the elastofibers class, elastane for example, and whose the coating agent may consist of either a fiber spun or a synthetic yarn, possibly textured in particular by false twist.
- fabrics based on elastomeric yarns also have a major drawback, namely their resulting high price, both of the materials which are part of their composition, only the molding operations necessary to obtaining them and they cause problems during their handling, dyeing especially.
- Such fabrics made from textured yarn can be produced at a price very competitive. From a practical point of view, however, these products are mainly used in the clothing industry and have not found of application in the field of seat coverings. By the way, this guy is generally dyed in pieces, which only allows fabrics plain or semi-plain, and does not allow for colored designs.
- the fabric obtained by the process according to the invention is made from polyester threads fake textured torsion.
- the threads are presented in the form of soft spools allowing retraction of the wire during the dyeing operation, which is preferably carried out in an autoclave at a temperature of the order of 130 ° C.
- Such a fabric can be based on any type of armor, whether it is armor plain, fancy, even Jacquard.
- the density of warp threads and weft yarn is calculated to be approximately 10 to 15% less than the density desired finish in the finished fabric.
- the washing operation is carried out so as not to affect the coloring of the threads, a temperature of 90 ° C. being suitable in the case of polyester yarn previously dyed, the heat treatment of finishing (treatment on oars) being carried out on an installation the interior of which reigns a temperature of 150 ° C, but which, taking into account the speed of passage of the fabric which is of the order of 15 m / minute, makes it only reaches a temperature of the order of 130 ° C.
- Weaving is carried out by keeping the warp threads under tension, the weft being inserted also under tension at the rate of 20 strokes / centimeter.
- the fabric obtained has a width of 152 centimeters and weighs 230 grams / square meter.
- Such an ecru fabric has a 10% long and wide stretch.
- the ecru fabric thus produced is subjected to a treatment making it possible to amplify these extensibility properties, a treatment which consists first of all of an operation washing at a temperature of 90 ° C. carried out on a “Jet” type machine, treatment during which the fabric is kept tensionless both lengthwise and large.
- the washing temperature is such that, on the one hand, it does not affect the qualities of the dye produced on the threads, and do not cause fixing thermal crimping of the wires.
- the fabric is subjected to a drying operation and fixing on a train.
- the ream is at a temperature of 150 ° C
- the speed of passage of the fabric is 15 meter / minute. Consequently, taking into account this speed of the passage, the rise in fabric temperature is limited to around 130 ° C °.
- the train is set so that the fabric is kept in the width obtained after washing, without exerting voltage, and also with an introduction boost.
- a finished fabric having a width of 145 cm and a weight of 255 grams per square meter.
- the density of warp threads is 30.5 threads / centimeter and that of weft of 23.8 threads / centimeter.
- Such a fabric has an elasticity of the order of 20% both in the direction chain only in the weft direction. This elasticity is determined by measurement on a dynamometer according to the test method defined by the automobile manufacturers French in standard D 41029 under a load of 5daN.
- warp and weft threads are made of textured polyester yarn each consisting of three ends having a title 167dtex / 30 strands, the number of warp threads being 4134 threads and the density at also comb of 26 threads / centimeter.
- the weft also consists of a false twist textured polyester thread formed of three pieces of 167 dtex / 30 strands previously dyed, with a reduction of 14 shots / centimeter.
- the fabric When the loom falls, the fabric is 152 centimeters wide and weighs 275 grams / square meter.
- a finishing treatment is carried out under the same conditions as in Example 1.
- Such a fabric has 28.5 threads / centimeter and 15.5 threads / centimeter.
- This fabric is particularly suitable for coating seats, especially for cars, and has very good characteristics of abrasion resistance.

Abstract
Description
- les fils texturés formant la chaíne et/ou la trame sont préalablement teints avant l'opération de transformation en tissu, et ce dans des conditions telles que les fils puissent se contracter pendant cette opération;
- l'armure du tissu est conçue pour que le tissu écru soit décontexturé en chaíne et en trame par rapport à la densité souhaitée dans le tissu fini ;
- l'opération de tissage est réalisée en maintenant les fils de chaíne et de trame sous tension ;
- Chaíne : fils polyester texturés par fausse torsion, chaque fil comportant deux bouts de 167 dtex30 brins, ayant été préalablement teints. La chaíne comporte 4498 fils et est réalisée avec une disposition de couleurs (trois coloris). Le peigne du métier comporte 13 dents/centimètre avec deux fils par dent, soit 26 fils par centimètre.
- Trame : fils polyester texturés FT similaires aux fils de chaíne. Les fils de trame sont également teints.
Claims (3)
- Procédé pour la réalisation d'un tissu extensible à la fois dans le sens chaíne et dans le sens trame et qui présente des effets colorés, utilisable notamment comme revêtements de sièges, les fils de chaíne et les fils de trame étant des fils synthétiques ayant reçu un traitement de texturation par fausse torsion, les rendant à la fois volumineux et extensibles, caractérisé en ce que :les fils texturés formant la chaíne et/ou la trame sont préalablement teints avant l'opération de transformation en tissu, et ce dans des conditions telles que les fils puissent se contracter pendant cette opération;l'armure du tissu est conçue pour que le tissu écru soit décontexturé en chaíne et en trame par rapport à la densité souhaitée dans le tissu fini ;l'opération de tissage est réalisée en maintenant les fils de chaíne et de trame sous tension ;
