TEXTILE WITH A CONTROLLED ELASTICITY FOR THE FORMING OF ELEMENTS OF GARMENTS, UNDERWEAR, ORTHOSES, AND SEAT ELEMENTS

Abstract

A textile for the forming of elements of underwear, of garments, of orthoses, or of seat elements having a controlled elasticity, integrating, at least in the direction of the main effort, stretch yarns having an elastic characteristic. Said stretch yarns are associated with more highly stretchable yarns, having greater stretching characteristics than those of the stretch yarns, the return force exerted by the low stretch yarns being in the range from 25 to 50% of that exerted by the high stretch yarns.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The foregoing features and advantages of the present invention will now be discussed in the following non-limiting description of a specific embodiment, in relation with the accompanying drawings.

[0023] FIG. 1 is a simplified longitudinal cross-section view of the work and of the positioning of the different types of yarns forming a textile according to the invention.

[0024] FIG. 2 is a perspective representation of the structure of the fabric.

[0025] FIG. 3 is the corresponding weave repeat.

[0026] FIG. 4 is an example representative of a loom threading draft for the forming of an elastic band having a 35-mm width, typically capable of forming a brassiere or sports brassiere strap.

DETAILED DESCRIPTION

[0027] As already indicated, the following embodiment more specifically concerns the forming of a woven band for the manufacturing of a shoulder strap for a brassiere or a sports brassiere, that is, for the forming of an element of a portion of a garment likely to be submitted to significant mechanical efforts, in the case in point, while practicing a sport.

[0028] Such an embodiment uses a conventional loom with a reed density of 10.25 dents per cm. It uses a double weft (T), each formed of a textured polyamide yarn measuring 2/78 decitex, the take-up of the finished fabric being 110 picks per inch.

[0029] Referring to FIGS. 1 and 2 for a better understanding of the fabric structure, the warp yarns comprise the following combination:

[0030] high stretch yarns (A) of covered yarn type, with a maximum 90% stretching, linearly inserted between the face weft and the back weft to favor the elastic return, formed of a 310-decitex elastane core covered with two layers of textured polyamide yarns measuring 2/78 decitex;

[0031] high stretch yarns (A1) of covered yarn type, with a maximum 160% stretching, linearly inserted between the face weft and the back weft to favor the elastic return, formed of a 940-decitex elastane core covered with two layers of textured polyamide yarns measuring 1/78 decitex;

[0032] yarns called core yarns (B), each being formed of a textured polyamide yarn measuring 2/78 decitex worked in a 3/1 rep weave on the two wefts;

[0033] yarns called shuttle threads (C), each being formed of a textured polyamide yarn measuring 2/78 decitex worked in a 3/1 rep weave on the back weft;

[0034] yarns called binder yarns (D), each being formed of a textured polyamide yarn measuring 2/78 decitex worked in a taffetas weave on the two wefts.

[0035] The textile element thus formed has a maximum stretching capacity of approximately 90% with respect to the initial length, and develops a return force for a 30% stretching in the order of 400 cN/cm.

[0036] Advantageously, to obtain the desired result, that is, the comfort on the one hand, and the holding on the other hand, the respective proportion of long stretch yarns and short stretch yarns is close to 50-50; only the elastic yarns on each selvedge are formed with long stretch elastic yarns to ease the forming of the edge.

[0037] Of course, the elastic characteristics of the textile element depend on its final application.

[0038] Thus, in the context of the forming of a shorts or underwear waistband, particularly for a use in sports, a textile structure similar to that previously described, but which this time has a maximum stretching from approximately 120 to 150% with respect to the initial length, in addition to a return force for a 30% stretching typically in the range from 200 to 300 cN/cm, is formed.

[0039] To vary the elastic characteristics of the involved yarns, the size of the core of the covered yarns and the actual covering are varied. Such a control of the stretching and of the consecutively generated return force is perfectly well known and within the abilities of those skilled in the art.

[0040] The described example concerns a woven article.

[0041] The invention also applies to textile structures obtained by knitting or by braiding, the main elements of the invention being kept.

[0042] One can understand the benefits of the present invention, which enables to simply obtain, whatever the envisaged application, a textile structure simultaneously enabling to ensure the function of elastic compression which is mainly required from it, and the comfort, which is desired in case of light effort or of no effort. This is thus particularly true when practicing a sport, although it is not limited to this type of application only.
