Abstract

The invention relates to the patterning of flocked textile Flaechengebilden which for outerwear, furniture upholstery fabrics, decorative fabrics, wallpaper u.a.m. are suitable. The object of the invention is to achieve by mechanical action with simple technical means an optically effective, durable pattern of flocked textile surface formations. According to the invention, this object is achieved by the fact that the textile fabric in the flocked state or as a carrier material, independently of the processing state, is stranded, compressed or shaped stranded by a single or multi-stage squeezing device, e.g. a padder, with variable contact pressure, is guided. The pattern formed after opening the textile fabric is fixed by heat.

Description

Title of the invention:

Method of patterning flocked textile fabrics

Field of application of the invention;

The invention relates to a method for producing patterns on flocked textilien fabrics. It is particularly suitable for the production of patterned flocked fabrics, the z. B. for outerwear, furniture fabrics, textile wallpaper u.a. are provided.

Characteristic of the known technical solutions :

It is known that textilien fabrics can be transferred by color printing pattern. For example, DT-OS 2 133 541 describes a method for producing patterns on textile fabrics by means of textile color printing machines. In DT-OS 2 349 194 a pattern by means of template or profiled brush is specified, which causes a stroke or by special design of the template patterning. Dessinierwalzen are offered by various companies to obtain patterned textile fabrics. Furthermore, GB-PS 1 279 814 describes a strip-shaped dyeing with the aid of a groove-shaped projection.

described direction. In US Pat. No. 3,899,292 Knautschen is mentioned together with the dye liquor by a section of reduced cross-section. It is also known that so-called tumblers are used to achieve a crushing effect and thus to obtain a pattern. Thus, additional technical devices are required by the known technical solutions or they are directly connected to another refining process, especially the dyeing process.

In addition, DD-PS 129 569 has already been proposed to achieve patterning in the context of electrostatic flocking, but this requires the use of profiled fabrics as Flockungsträger and thus limits the application.

Aim of the invention ;

The aim of the invention is to supplement the known variants and methods for producing patterns on flocked textile fabrics and thereby to dispense with the required in the prior art use of additional devices such as Dessinierwalzen and / or color printing machines and the pattern even without other requirements How to make profiled fabrics for flocking or the combination with the dyeing process, economically favorable and in appealing quality.

Explanation of the essence of the invention :

The invention is based on the object by mechanical action with simple technical means an optically effective, durable pattern of flocked

textile fabrics.

Erfindungsgernäß the object is achieved in that the fabric in the flockedüi condition or as a carrier material, regardless of the processing state, stranded, compressed or shaped, optionally with additional dry or moist heat, by a single or multi-stage Abquetsclworrichtung, e.g. a Foulard, with variable contact pressure, is performed. The resulting after opening the textile fabric on this pattern is fixed by heat in a tensioned state with the possible addition of known fixatives

 At the same time, the drying of the textile fabric can be carried out.

In the treatment of carrier material. After the process according to the invention is then carried out on one side of the adhesive application, the electrostatic flocking and the treatment for curing of the adhesive.

The fabrics produced according to the invention have a very high resistance of the achieved patterning effect.

The invention will be explained in more detail in the following examples:

Embodiment 1 ;

A flocked fabric, consisting of a textlien carrier made of cotton, an adhesive layer based on polyacrylate and PA short fibers of fineness of 1.7 dtex, 0.5 mm cut length is after condensation of the adhesive layer and leaving the dryer, a moistening of the material means Water ahead

taken, subsequently in strand form, passed through a 3-Walzenfouiard at a pressure of 0.5 MPa and dried over a drying frame in a strained form at 175 ⁰ C and fixed. The result is a flocked textile fabric with a discreet irregular pattern.

Embodiment 2 :

A roughened Polyamidkettengewirke is moistened with water of 98 ⁰ C, which additionally contains 150 g / l of benzyl alcohol as a swelling and fixing agent, and stranded together by a 2-roll pad with a contact pressure of 0.4 MPa out. This is followed by the treatment at 104 ⁰ C in a Dämpfkanal, open and • drying as a web on a Spannfixierrahmen and fixing at 180 ⁰ C. Subsequently, a polyacrylate adhesive with 0.2 mm overlay, then PA short fiber with a conventional flocking system 1.7 dtex, 0.5 mm applied in the electrostatic field and cured.

The result is a flocked textile fabric with a discreet irregular individual pattern.

Embodiment 3 :

A Polyamidseidengewirke, made of PAS 4.4 tex 2 is placed in rope form and treated in a liquor consisting of 8 parts of water and 2 parts of benzyl alcohol at 85 ⁰ C and then treated in a 3-roll pad at a contact pressure of 0.6 MPa. Subsequently, the Polyamidseidengewirke is opened and dried under the action of hot air in the tensioned state as a web and fixed at 180 ⁰ C. This is followed by the application of a 0.15 mm thick polyacrylate-based adhesive layer on one side. The electrostatic flocking is performed with 3.3 dtex, 0.5 mm PA short fiber.

taken and cured the adhesive. The result is a sheet with subtle individual patterning.

Embodiment 4 ;

A flocked textile fabric, consisting of a textile polyester silk fabric, a polyacrylate-based adhesive layer and PA short fibers of fineness of 6 dtex 1.0 mm cut length is pressed after condensation of the adhesive layer in strand form under Heißlufvonvvirkung of 195 ⁰ C at 0.6 MPa. Subsequently, the material is moistened and dried in a stretched state as a web with hot air of 200 ⁰ C and post-fixed.

The result is a subtle pattern of the flocked textile fabric.

O u rd e s t i o n s ρ i e 1 5:

A flocked sheet, analogously to Example 4, is extruded in a dry state under saturated steam action stranded and pressed on the pad with a contact pressure of 0.4 MPa and fixed for 10 min, then treated as a web in the tensioned state at 150 ⁰ C with hot air.

The result is a sheet with a discreet, irregular, individual pattern.

Embodiment 7 ;

A flocked fabric of Example 4 is transversely compressed in the wet state to the web, in a press at l _f 5 MPa pressed and treated under wet heat exposure at 120 ⁰ C at 0.25 MPa, then dried at 185 C in the tensioned state with hot air and fixed ,

It is a sheet with a discreet, irregular, stripe-shaped pattern achieved.
