Definitions
- the present invention relates to the technical sector of the clothing industry and relates more particularly to a new type of sheet support used as a conveyor / conveyor element of a mattress made up of a plurality of superposed textile layers and which is intended to be cut. in the form of elementary panels of suitable shape to be subsequently assembled together to produce the final product such as clothing.
- the fabric mattress is placed on a breathable support and the cutting into elementary panels is obtained by creating a depression below said table, so that the stack is kept perfectly pressed during the cutting phase.
- the mattress is covered at its upper part by a film plastic, airtight, which makes it possible to densify said mattress at the time of the cutting phase and prevents any displacement of the elementary layers with respect to each other.
- the support consists of a layer of material into which the tool can penetrate and which has channels or passages, which allows, under the vacuum exerted below the stack, to exert a suction action tending to press the material against the support table.
- the most used solution consists in having relatively rigid papers, perforated by stamping or scratching, below the stack, which have the essential advantage of being relatively low cost.
- the perforation is necessarily performed after the manufacture of the paper and therefore results in the production of waste.
- the object of the invention is to propose using a paper sheet permeable to air as a support element for a stack of fabric on a clothing line, in particular as a support during the cutting phase.
- a paper sheet permeable to air as a support element for a stack of fabric on a clothing line, in particular as a support during the cutting phase.
- Such paper sheets are known per se as is apparent in particular from patents EP-A-616,074, EP-A-483,816 and EP-A-426,288 and have been proposed for producing articles having a high absorption capacity of liquids with a view in particular to using them as wiping materials, hygiene articles, etc.
- a sheet As a paper sheet intended to serve as a support, a sheet will be used which has in its thickness pores or fine perforations distributed over its entire surface, said sheet having a "volume” or "hand” expressed in cubic centimeters per gram, greater than 2.5, making it suitable for allowing the passage of air under the effect of a suction produced below its underside.
- the sheet structure has pores uniformly distributed over its entire surface, said pores having a diameter less than one millimeter and preferably between 50 and 150 microns.
- the pores or fine perforations are distributed in the form of patterns comprising a central area with high air permeability surrounded by a denser fibrous area with lower permeability.
- the pitch between the centers of two consecutive patterns is less than 5 mm and preferably less than 3 mm
- the central zone with high permeability is free of fibers and has a total surface of the order from 1 to 2 mm 2 .
- the invention also relates to a process for obtaining a paper sheet usable as a support element for a stack of fabric on a clothing line, which consists in producing a filter paper directly on a paper machine, without particular adaptation, characterized in that when obtaining said paper: - during the preparation of the pulp, the cellulose fibers (wood pulp) are individualized without refining them too much in order to preserve the maximum permeability;
- the sheet produced is not compressed in the wet part of the machine in order to maintain its permeability.
- the permeability is maximized by subjecting the paper sheet produced, before drying, to a texturing treatment which consists in locally displacing the fibers by means of jets or blades of fluid through a canvas.
- a texturing treatment which consists in locally displacing the fibers by means of jets or blades of fluid through a canvas.
- coarse texture or of a perforated cylinder of the rotary printing cylinder type of screen printing type so as to form patterns comprising a central region of high air permeability surrounded by an area of lower permeability.
- the latter may have the consequence of either leaving only a small minority of fibers in the central part, or possibly achieving a real perforation free of fibers.
- Such a treatment can be carried out on machines of known type, for example of the type which is the subject in particular of FR-A-2 625 937.
- synthetic fibers such as polyester, polyamide, polypropylene, polyethylene, or even artificial fibers such as viscose or even natural fibers such as linen or cotton can be used.
- the optional binders will be chosen from the following elements, possibly combined with one another: - conventional polymers also called “LATEX” in particular of the acrylic, ethylene-vinyl-acetate, vinyl acetate, polyvinyl alcohol, styrene-butadiene type, etc. their polymers associated by co or ter ... polymerization;
- thermobonding fibers
- - Figure 4 is a reproduction, with an enlargement of the order of 200, of a sheet structure in which the pores are distributed uniformly over the entire surface of said sheet and;
- - Figure 5 is, in turn, an enlarged reproduction of the order of 30 of a sheet structure having received a texturing treatment ensuring a reorientation of the fibers.
- a paper which can be used in accordance with the invention as a support element for a stack of fabrics on a clothing line from a conventional paper composition consisting of 77% unbleached Kraft pulp of the southern pine type, and 8% unbleached fluff pastry.
- Binders consisting of 5% pregelatinized cationic starch and 10% vinyl acetate latex are incorporated, these binders being incorporated by any conventional technique such as padding, spraying or printing or “size press” and in the present case, a "size press”.
- the finished product After drying and crosslinking, the finished product is wound to the width desired by the user and has a structure as illustrated in Figure 4.
- a paper sheet is produced which can be used in accordance with the invention as a support for a stack of fabrics by proceeding, before addition of the binder as in Example 1, to a texturing treatment by passage over a conventional blade treatment machine or conventional fluid jets of the type sold by the company ICBT PERFOJET.
- a paper pulp comprising, as in Example 1:. 77% unbleached kraft pulp of the southern pine type and;
- the whole dough is defibrated / refined at only 15 degrees Schopper-Riegler at around 30 g / liter of water.
- Example 2 As in Example 1, a sufficient supply of water is produced on the circuit to obtain a final dilution of less than 1 g / liter, in this case 0.3 g / liter, which ensures uniformity. fiber dispersion.
- the fibrous web still wet thus formed receives a microperforation treatment by blade or jet of fluid on a conventional installation of the type PERFOJET, with perforated cylinder or through an open structure fabric with a water pressure of 5 to 80 bars.
- a microperforation treatment by blade or jet of fluid on a conventional installation of the type PERFOJET, with perforated cylinder or through an open structure fabric with a water pressure of 5 to 80 bars.
- a treatment makes it possible to locally obtain a partial or total displacement of the fibers according to the design of the cylinder or the mesh of the canvas.
- the treatment is carried out with a blade of water at 9 bars.
- binders are added by any appropriate means, padding, spraying, printing or “size press”, these binders being based on a composition comprising 5% pregelatinized cationic starch and 10% vinyl acetate latex.
- the finished product After drying and crosslinking, the finished product is wound to the desired width for the intended use, having a structure as illustrated in FIG. 5.
- Example 1 Compared to Example 1, a paper is obtained which has a significantly higher permeability than previous papers and which, compared to the product produced according to Example 1, makes it even more suitable as a support for a stack of fabrics. on a clothing line.
- Example 3 Example 2 is repeated except that incorporating reinforcing fibers into the paper pulp.
- the aqueous composition comprises 72% of unbleached kraft pulp of the southern pine type and 9% of unbleached fluff pulp.
- the whole dough is fiberized / refined at only 18 degrees Schopper-Riegler and 5% polyester fiber, 1.7 decitex - cut 18 mm is incorporated.
- the mixing in water is carried out at a rate of approximately 15 to 20 g / liter.
- a wet resistance agent consisting of 0.7% of polyamide epichlorohydrin resin is added.
- the addition of water to the circuit is carried out in such a way that a final dilution is obtained of less than one gram / liter, making it possible to ensure the homogeneity of the dispersion of the fibers, which in this example is 0 , 3 g / liter.
- the wet fibrous web thus formed is textured in a similar manner to Example 2, the fluid pressure being 11 bars and the water layer having been replaced by jets of fluid, at the rate of approximately 100 jets / needles per meter of width making it possible to obtain a structure similar to that of Example 2 and which emerges from FIG. 5.
- a complementary bonding is carried out by depositing a composition of 5% pregelatinized cationic starch and 10% vinyl acetate latex.
- Such paper is also perfectly suited to serve as a support element for a stack of fabrics on a clothing line.
- the uniformity of the sheet ensures better sliding on the cutting surface without fouling of the latter; • such a sheet being perfectly flat, this eliminates practically all risks of marking on the surface of textiles, in particular in the case of fine textiles; . due to its uniformity, such a sheet ensures a more homogeneous thickness of the mattress, thereby ensuring better cutting of the textile; . the uniformity of the sheet also ensures a generally reduced thickness due to the absence of bumps and hollows, which allows consider increasing the number of layers of fabric in the mattress and; . finally and above all, it is possible to use such a support whatever the type of fabric entering the stack, whereas, previously, it was appropriate to use ranges of perforated paper having different characteristics.
