Description

The invention relates to a method zttr Dimensional stabilization of garments by containing an air-permeable, thermoplastic material Insert that is intimately connected to the piece of fabric to be stabilized by ironing, pressing or the like.

It is known to use fabrics for clothing to be made with weft or warp thread from cellulose acetate. The cellulose acetate threads have thermoplastic Character so that they are made using solvents or dissolving agents and by heat and Print can be combined with an outer layer. Such a method has the disadvantage that by the use of solvents or heat, the final composite is non-porous, because in the treatment mentioned the cellulose acetate threads become plastic and at least partially result in a continuous, dense, non-porous structure. Cellulose acetate also has the disadvantage that it is not is boil-proof, becomes brittle when ironed and loses its adhesiveness, and is soluble in cleaning agents is.

It is also known to convert a screen-like perforated film made of thermoplastic material into corresponding Parts, e.g. B. collar, lapel, etc., iron in hot to bring about a stiffening of these parts. With this method, too, the screen-like holes previously provided in the film close because the heated foil comes to the flow. So you get also hereby no porous garment, as it is desired.

It is also known to apply a thermoplastic layer to a fabric by suction of air during the plastic state to make it porous. This procedure is used to make tent tarpaulin etc. impermeable to water on the one hand, and permeable to vapor and air on the other make, because so small pores are formed when air is sucked through that water because of its Surface tension does not penetrate the pores, but air can pass through the pores. Fabrics produced in this way are generally unsuitable for clothing, as they are on one side are provided with a thermoplastic layer. Would such a tissue now on one If the outer fabric are ironed on, the pores would be closed and the composite would lose its breathability.

The invention now has the purpose of providing garments with shape-retaining thermoplastic inserts are provided to be treated in such a way that the garments become porous.

The method according to the invention consists in that during the connection process of the stabilizing material with the fabric to be stabilized across

Air is conveyed to the fabric web. The advantage of this method is that the air conveyed transversely to the fabric web makes the thermoplastic material permeable to air, so that the item of clothing is porous, ie breathable.
In order to allow subsequent shaping processing

a ₅ save, it is particularly advantageous that the ironing and pressing is carried out on documents that correspond to the shape of the garments to be produced. In this method, the garment is given a shape appropriate to the purpose at the same time as the interlinings are connected to the fabric and the stabilizing material is made porous, so that a further operation is saved. Further details of the invention can be seen from the description of the exemplary embodiments shown in the drawing. It shows

The cross-section shown in Fig. 2 through a cut part of a piece of clothing shows a wool outer fabric 1, on which a plastic impregnated or coated, in this case porous fabric insert 2 is attached by surface adhesion (at 4). Various tailored and erfmdungsgegemäß processed cloth parts are in Fig. 2 a, b and c referred to, wherein α an upper sleeve, a back part b and c is a pocket flap with corresponding seam allowance 5 represent. Of course

In this way, the inlays 2 can also extend beyond the seam edges are sufficient.

In Fig. 1 2 warp threads 3 are shown in the fabric insert. Between the fabric insert 2 and the Fabric 1, a porous binding layer 4 is provided. the

Claims (2)

Impregnation or coating of the fabric insert can consist of known, polymerizable plastics, such as. B. polyvinyl chloride, polyvinyl acetate, polyethylene, polyvinylidene chloride or polyvinyl alcohol. The porous fabric insert can be impregnated, coated or provided with the binding layer 4 by prefabrication, the insert shown in this example having obtained its porosity before the hardening of the plastic by the action of a stream of air. To produce the cut part of a garment according to the invention, the procedure is such that the cut outer fabric 1 is covered with the cut, prefabricated, porous fabric insert 2, in this case leaving the seam edge free. The cut outer fabric 1 is then connected to the placed fabric insert 2 by hot ironing, with both parts being given their final shape at the same time by a correspondingly shaped base. Depending on the type of material, temperatures of 60 to 200 ° C and pressures of z. B. 1 to 3 kg / cm2 into consideration. A known air suction device maintains the pores 10 of the preliminary product or the formation of pores in the plastic. Instead of suction air, compressed air can of course also be used. Instead of ironing, the two parts can also be connected by hot pressing with air suction. The procedure is such that between appropriately shaped press die halves, at least one of which is heated and of which the other has an air suction device, the cut fabric 1 is connected to the placed tissue piece 2 by pressing and heating and at the same time is brought into a corresponding shape. The plastic remains or becomes porous as a result of the air suction. In this process, the heated part, the iron or the one press die half, expediently acts on the fabric insert, while the air is sucked off through the outer fabric. The reverse arrangement is also conceivable. The prefabrication can also be completely or partially dispensed with by z. B. at least the binding layer 4 is applied shortly before the heat treatment under pressure and with air suction as a layer on the fabric insert and / or on the outer fabric and then the above-described heat treatment with air suction takes place for the purpose of forming pores. However, the first-mentioned method is more appropriate. The air suction necessary when ironing or pressing to maintain or create the ίο porosity of the binding layer or the insert is carried out by a beech wood or metal base provided with suction channels or by a porous covering of a correspondingly shaped base (ironing pad) or by known supported metal mesh, which with Ironing material can be covered. The cut fabric inlays can also be sewn to the outer fabric before or after ironing or hot pressing. A possible shifting of the insert 2 on the outer fabric blank 1 is avoided during the previous sewing. If necessary, the suture threads can be removed from the upper side after the heat treatment of the cut part. Patent claims: 1.
