Abstract

The invention relates to the design and consolidation of the edge in textile fabrics, preferably flocked textile fabrics and floor coverings. The aim and object of the invention is to achieve a decorative design of the edge with simultaneous edge consolidation in textile surfaces that are cropped or divided in their preparation or have a design or strength moderately insufficient degree. According to the invention, an air-drying, moisture-resistant, elastically lasting adhesive is applied to the edge and / or side surface of a textile surface structure and anchored in the not yet cured adhesive flocculants.

Method of edge design of textile fabrics

The invention relates to the design and solidification of the edge of textile fabrics, for example, on textiles and used textiles on flocked textile floor coverings, such as floor coverings.

Textile fabrics are provided with a firm edge to improve the value of use, in order to meet mechanical and decorative requirements.

This is achieved by means of a Kant® "which is designed as a selvedge or knitted edge ©"

Representative good is required, eo a post-treatment is made. Known methods here are edge trimming "bordering by stitching or gluing, the melting of the edges of meltable fully synthetic fibers or fiber mats, the edges of the edges and the vulcanization with rubber.

The disadvantage of the known methods is that the edge of the figure is not in harmony with the structural and color characteristic of the surface of the textiles. They are not applicable to textile fabrics with back coating of synthetic foams only conditionally.

01® Adjustment of the edge attachment to the design of the textile fabric is carried out by similarly stitched sewing thread, held in the same color or pressure hem band and colored adhesive ·

In the case of velor blankets, for example, a band of the same name is used, in the case of woven rug a woven band dyed in the basic tone of the carpet, in carpet knit a knit tape held in the basic tone of the carpet.

Flocked textile fabrics, in particular flocked textile foot coverings with show pieces, are cut on all sides as plain or printed fabric at the edges and during processing into runned goods and the like. The stoS and abrasion-sensitive edges are attached by sewing a thread seam, by stitching, by bonding with border, by fusing or gluing the edge.

Z 4 S U U O

The goal of the Dl® invention is to achieve, by means of a low technological expenditure, a decorative value-enhancing design of the border of textile surface blasts in accordance with the character of the product with simultaneous edge hardening.

^the

The object of the invention is in textlien Flächengehiiden * preferably flocked textlien Flächerigebllden or Schlingpolware «be cut or divided in their preparation or have a design and strength inadequate conclusion to achieve a © decorative design of the edge with simultaneous edge hardening.

The object is achieved in that applied to the edge and / or side surface of a textlien fabric a lufttrocknender, moistresresistsrtter, elastically resistant adhesive and anchored in the not yet cured adhesive flock fibers so that they are only partially detected by the adhesiveβ

The application of the adhesive takes place in an amount of 50 500 g / m, preferably by means of doctor rollers, at the edge and / or on the side surface of a textlien fabric.

Adhesives are based on dispersions of SBR latex, NBR latex, PVac, PAC or solutions of natural rubber in gasoline, polyurethane in halogenated hydrocarbon or elastisch® heat-shrinkable compositions with a melting range between 350 and 450 K.

Prior to curing of the adhesive anchorage of the adhesive Flockfssern in by mechanical, pneumatic UNU / Qu®r electrostatic flocking with a flock fiber layer 30 is - made 500 g / a ·

The flock-fiber overlay is preferably pressed mechanically in the adhesive direction.

Surprisingly, it was found that a curled edge and / or side surface in flat textiles in addition to the Randbefestigungsfunktion a particularly decorative Gestaitungeelaraent largely adapted to the character of the product, which leads to a homogenization of the cross-sectional image especially when using foam backing to the side surface represents a closed unit to the product surface ·

A prerequisite is that flock fibers of the same hue or flock mixtures of different matched hues, which are coordinated with the surface design of the fabric, are applied in a statistically distributed manner.

Secondary flock fibers of different lengths are suitable for the process according to the invention.

After the adhesive has hardened, da® becomes a sheet

cleaned of surplus, non-adhesive flock fibers.

The invention will be explained to Ausführungsbeiispielen

Subsequently, the application of uniformly sand-colored flock fibers to the adhesive layer is carried out by pneumatic duster irradiation

at the cut surface. About 200 g / n flock fibers, a short-flocked or ground-flock mixture with a flock length of 0.2-2.0 mm are partially embedded in the adhesive layer in complete random orientation.

After partial drying, the applied flock layer is pressed by means of a moist rubber roller in a lateral guide *

After complete curing of the adhesive, the flock layer is intimately connected to the edge of the carpet and shows a very good use behavior ·

It is achieved a cut resistant edge of the carpet, which shows a very good optical finish and close to the properties of the surface of the carpet gaps.

After cooling, the flock fibers are anchored very stable and form a visually effective hard-wearing completion of the carpet piece.

A poled piece of carpet (loop or cycle character) is applied to a rigid applicator, e.g. Squeegee coated with a PVC paste on the edge and on the side surface «The side surface of the carpet piece is coated completely and at right angles to this then a marginal width of about · 0.5 cm of the surface (order wet approx. 300 g / m). By electrostatic application flock fibers are introduced into the still plastic adhesive. The adhesive is then gelled by the action of heat and forms a very durable and decorative finish with the flock fibers.

On a carpet edge, a heat-sealable elastomers double-sided coated textile tape is laminated under heat and pressure.

Simultaneously with this Kaschiervorgang flock fibers are applied by electrostatic flocking on the wärmeplaetischs band and fastened with the necessary pressure for laminating evenly in the adhesive. The top shot flock is brushed off and sucked off and can be put to a new use »
