Definitions
- the present invention relates to a polyester fabric, all fibers, having elasticity properties in relatively large proportions significant, of the order of 15 to 20%, without the use of materials from the elastomeric type. It relates more particularly to a method of manufacture of such a fabric using polyester fibers bi-compound with bimetal structure capable of developing a helical crimp and spiral. It also relates to a fabric obtained by said process.
- textured threads makes it possible to obtain a polyester fabric with high elasticity but this use of course excludes that it is a all-fiber fabric, textured yarns being by nature continuous yarns.
- the elasticity can be conferred by using a certain proportion of elastomeric fibers, especially elastane.
- fibers bi-composite with bimetal structure i.e. synthetic fibers having two juxtaposed components having characteristics different chemical or physical, these differences causing subsequently a certain crimp of said fibers.
- the RHONE-POULENC FIBERS company presented in 1984 a fiber polyester, called X403, of this type.
- this fiber has a bimetal structure of which the two components, juxtaposed longitudinally, are chemically different polyesters, obtained from two diols different. According to the producer this fiber develops a crimp helical and spiral which gives it a swelling and extensibility, like what is obtained with textured threads, except that spun with fibers, whether pure or mixed, have no extensibility, the crimp and therefore the extensibility being revealed only during dyeing or various heat treatments performed on the fabric.
- RHONE POULENC FIBERS recommended to carry out the following sequence of operations on the unbleached fabric, namely washing, heat treatment at 190 ° C for about 30 seconds, dyeing 130 ° C, skinning after dyeing, drying on reams, brushing / shaving and primer and finishing.
- the goal set by the applicant is to propose a method of manufacturing which overcomes the aforementioned drawback, that is to say which allows obtain a polyester fabric under industrial conditions, all fibers, elastic with a certain proportion of polyester fibers bi-compound with bimetal structure, able to develop a crimp helical and spiral.
- the method comprises operations of preparation of the mixture of fibers, spinning, weaving and various tissue treatments.
- the preparation and spinning leading to a non-extensible yarn and the fabric being strongly decontextured to take into account its potential elasticity we submit the unbleached fabric at a heat pre-treatment, in hot air at a temperature between 180 and 190 ° C under very low voltage, prior to all conventional treatments in a liquid medium, especially washing and dyeing; moreover during all operations subsequent to the heat pre-treatment, the tension of the fabric is limited.
- the first treatment that must undergoing the off-white fabric is a dry heat pre-treatment, any treatment preliminary aqueous in hot water of the washing type being to be avoided in the extent to which this results in a consequent loss of potential extensibility of the bi-composite fibers on the final product.
- This dry heat pre-treatment should be followed by precautions during subsequent treatments to limit tension exerted on the fabric.
- the dry heat pretreatment consists of a rowing for a period of 1 minute to 1.5 minutes approximately at a temperature of the order of 185 ° C.
- the passage in rowing is carried out with a rowing advance of around 15% and a width adjustment in oar output of the order of 9% weaker than the width of the unbleached fabric.
- the operations preparation of the fiber and spinning mixture could be a source of loss of tissue stretch potential.
- Being a fabric polyester / wool conventionally, there are first operations carried out on each type of fiber leading to formation on the one hand woolen ribbons and on the other hand polyester ribbons; the fiber blend is made from these two types of ribbons - called tops - with a repainting operation integrated into the spinning mill.
- the mixture of fibers is produced directly by carding and spinning is free repainting operation.
- the bi-composite fiber with bimetal structure which will be discussed in this description is the polyester fiber sold under the name X403 by the company RHONE-POULENC FIBERS.
- the current invention is not however exclusive of this fiber and can be applied any bi-composite polyester fiber of the same type, able to develop a helical and spiral crimp, approaching the natural crimp of wool.
- polyester / wool of the order of 50/50
- the blend of polyester fibers and wool fibers are made from ribbons, called tops.
- the fibers of wool and polyester are subjected to parallel operations, including carding and combing for wool.
- Mixed tops are, before spinning, repainted before the doubling operations on gills, then the passage on a spindle bench and finally on continuous spinning.
- the circuit above mentioned has been replaced in order to avoid the repainting operation before spinning which, according to the findings of the is likely to thwart the potential for scalability of polyester fibers on the finished fabric, after revealing the crimp.
- the mixture polyester / wool is carded from fibers from a fiber feed mixer.
- the circuit is therefore as follows. We make a premix, in a mixer, from bales of polyester fibers X403 on the one hand and wool fibers on the other. In a specific and preferred example, the mixture is made from two kinds of polyester balls X403, different cuts: some of weighted average height of 80 mm and the others of 105 mm.
- the mixer has means for working the material, for example a beating comb, weighing means and means of transport to supply the cards in the right proportion of polyester and wool fibers. These fibers are subjected to successive carding and combing leading to the formation of tops, then to the operations of doubling on gills, passing on a spindle bench then on continuous spinning.
- the yarn produced at this stage has no extensibility, the crimping of polyester X403 which has not yet been revealed.
- weaving operations must take into account the potential elasticity of the finished fabric. This fabric should be, during weaving, strongly decontextured so as to leave room for the strong withdrawal that will have to operate the threads later, when the crimp is revealed.
- the fabric of plain weave, consisted of wires Nm 2/70 (286dtex) in warp and weft. It included 19.5 picks / cm in the weft (instead of 23 picks / cm usual) and in 3485 thread chain for a width of 180cm (instead of 4100 usual sons). The fabric was therefore decontextured on the order of 17.6% in chain and screen, knowing that the extensibility sought should be in the range of 15 to 17%.
- the ecru fabric Being strongly decontextured, the ecru fabric must be handled with care, especially during unwinding, during operations subsequent.
- This off-white fabric is typically subject to according to the method, a dry heat pre-treatment, in the form of a rowing at a temperature between 180 ° C and 190 ° C, preferably 185 ° C. It is during this heat pre-treatment that develops the helical and spiral crimp of X403 polyester fibers.
- the fabric fits from 6 to 8%.
- the rowing in question was conducted with minimum tension setting, 15% feed and setting width leading to a width of approximately 170cm for the ecru fabric at 156 cm at the end of the train.
- this heat pre-treatment is not preceded by washing the unbleached fabric, it is important to be particularly vigilant to cleanliness during weaving, this pre-treatment can fix certain soiling.
- ream drying at 130 ° C is considered by the applicant as an important step, before the first treatment thermal, to obtain the optimization of the extensibility which is wanted.
- the finished fabric has a width which in the end is of the order of 142-143 cm and an extensibility of 15 to 16% in chain and from 16 to 17% in frame.
- the present invention is not limited to the precise mode of realization which has just been given by way of non-exhaustive example. he can be all-fiber fabrics containing other types of fibers than wool, mixed with bi-compound polyester with bimetallic structure, as well than other mixing ratios.
