Description

The invention relates to a method for manufacturing a textile article in a tablecloth

  a flock consisting of a substrate, a layer of glue and a layer of short fibers (flocs), and according to which a layer of aqueous glue is deposited on the surface of the substrate and flocked into the entire thickness of the surface of the glue layer, a layer of

  flocs formed by short fibers essentially vertically

  and prepared by electrostatic action, and the flocked sheet article obtained is dried, fixed so that it takes a fixed structure, is subjected to a surface treatment, it is optionally subjected to a finish,

  then rolled up removing the remaining fiber

  flocs, and on the other hand an article in nap-

  soft flocked peel consisting of a substrate, a layer of

  glue and a layer of floc and having characteristics

improved.

  Textile flocked textile articles are known from the textbook "Textile Raw Materials", 6th edition 1981, E. Wagner, page 159, in the form of imitations of suede, velvet, plush and skin and as

  velvet paper and articifiable leather.

  Such a tablecloth textile article is submitted by

  example to a compression process (crash process).

  As auxiliary provisions, it implements loopback means. It is further known to emboss web articles. In order to obtain reasons and

  color effects it is known from the German patent.

  No 832 112, to process a flocked sheet article at

  using air splashes. The inclination of the fibers

  the floc is then modified in different directions.

  The known flocked tablecloth articles are

  of coarse invoice time, not very flexible, and their over-

  face is matte, has no finesse and is rather

  parable to a felt. Their possibilities of use are limited, and this in relation to their resistance to wear, their elasticity and their touch. The known treatments of

  finishing are expensive and increase the price.

  The object of the invention is to create a flocked web article which can be obtained with finishing at a cheap price, and which has a quality and possibilities of use markedly improved by

  compared to flocked flat or flocked products.

  On this subject, for example, bi-elasticity

  quoted, touch, wear resistance, permeability

  in air, insulating action and appearance. The finesse of the sur-

  face of the flock layer must, at choice, present the

  drape, wool piqué or flannel, depending on the purpose of further use. These are qualities that can only be achieved in the textile industry

expensive textile equipment.

  The technical problem underlying the invention consists in improving the process of the type indicated above in that the flocked web article is subjected to a uniform mechanical treatment in order to obtain in this manner, at an attractive price. , a finished flocked tablecloth article

improved features.

  This problem is solved according to the invention by the fact that after flocking, it calender the article in

  a web consisting of a substrate, a layer of aqueous glue,

  se and a layer of flocks. Beforehand, we eliminate

  in sheet form the floc fibers which are in excess. This

  preferably by means of aspiration of the

excess flocks.

  The flocked web article has a flocked surface in a uniformly dense manner and then receives,

  under the effect of calendering, a continuous pressing treatment.

  This pressing treatment exerted using cylinders modulating

  difies the thickness of the layer and performs a uniform folding of the free ends of the fibers forming the flocs

  and performs additional ncrage of the inserted ends.

flocked.

  At the surface of the flocs we obtain a

  uniform sense of the fabric. The fibers forming the flocs

  serve, without modification, this position during the processing

  afterwards by drying and fixing and give

  face a fine or extremely fine aspect presenting the quality

  drape, piqué wool or flannel.

  If the calendering is done when the layer

  glue is in the wet state, the fine surface takes

  silky pect accuses, while when the layer of glue is half wet, this silky aspect is slightly less pronounced. If the calendering takes place while the adhesive layer is air dried or is starting to dry, the flock layer provides a dull subsequent appearance. The degree of surface smoothness and gloss can be further influenced by the choice of calendering

cold or hot.

  Thanks to the implementation of the compliant treatment

  the process and constitution of the textile article in nap-

  eg, which has a substrate as the support material and a flock-on layer of glue, improved characteristics for the novel flexible web article, with a fabric and / or a layer of foam or a foil, are certain to be obtained. level of its underside and a layer

  of foam-forming glue as well as the layer of flocs at

  calf of its upper face. The tablecloth article has not only a fine appearance, but is also soft and supple. Until then we had not obtained these results

  in flocked tablecloths. The pre-tableted article

  feels a great resistance to wear. The uniform sense of

  The orientation of the flocs does not vary in the case of superficial friction. The sheet article is lightweight and on the other hand is flexible, bi-elastic and breathable. It has good insulation characteristics and can be treated

  easily and simply as a coating material

is lying.

  Woven products with such characteristics

  This would require comparatively expensive textile equipment, such as linear wool and warping. However in woven products one can not get all the characteristics that are proper

  of the flocked web article previously described.

  According to another embodiment of the invention, it is also possible to emboss or partially emboss the calendered flocked sheet article. Depending on the desired pattern, you can

  obtain for example the following images or drawings:

  donation, cloth or sheet weave of the character

  coarse to fine character, herringbone pattern or

  plaid, striped or line armor or any type of armor

fancy mure.

  The effects of embossing should not be identi-

  clearly defined. They can be apparent only in the case of a variable refraction of light. The effects of embossing can also be predominantly identifiable with a rustic appearance. It can be achieved that the structure extends over the height of the flocs. The gloss of the surface is interrupted differently as a result of the embossing effects so that the surface has

an additional plastic effect.

  Changes can be made in the

  by calendering, drying and embossing by the fact

  instead of embossing immediately after

  firstly, the article is produced by drying the calendered flocked sheet article and then subjecting it only to embossing. As a result the contours of the embossing

  become more clearly visible and this gives the sur-

face a decorative aspect.

  The possibilities of variants are not only

  by the operating steps described in accordance with the

  vention, but also by the use of

  may, however, be chosen for the subsi-

trat, glue and flakes.

  The substrate may consist solely of a type of fabric, a knitted product, a Rachel product or a similar carrier. But it can also be in the form of a two-layer product, for example by being covered with a layer of flexible foam or a flexible sheet. These sheets or layers can be fixed

  by doubling and preferably being applied to the flank.

  Preferably, the adhesive may consist of an aqueous dispersion foam adhesive, especially an adhesive

  polyurethane foam or an adhesive formed of an acrylate

  late, because of the lightness of the structure stability and the air transparency of these materials. These are very suitable for use with flocked tablecloths. They are non-pollutants, formed of cells of large dimensions, light and of a stable structure and

  adhere very well to the substrate and flocks.

  The fibers constituting the flocs influence

  characteristics of the superficial structure, in

  function of the material, the title and the cutting length.

  In the case of flakes made of viscose, with a title

  weak and have an average length, the item in bar.-

  presents a softer feel than in the case of flocs

  of polyester. In the case of polyamide, the fineness of

  for example, between 1.7 and 3.3 dtex. In general, the length of the fibers will preferably be between 0.5 and 1.5 mm and the fineness between 0.9 and 3.3 dtex. In principle, it is possible to use all known types of floc for the insertion of short fibers.

  by flocking in a flocked layer preferably over its entire thickness.

  Other features and advantages of the pre-

  invention will emerge from the description given below.

  after reference is made to the accompanying drawings, in which:

  FIG. 1 schematically represents an installation

  to make a textile article made of fluffy flexible

  qué, comprising a calendering device; FIG. 2 diagrammatically shows another installation used to manufacture a flocked flexible napkin article comprising a calendering device and

an embossing device.

  Figure 3 schematically shows a portion of a variant of the installation of Figure 2; and Figure 4 schematically shows a portion

  another variant of the installation of FIG.

Example 1

  The substrate consists of a product formed of polyamide filaments weighing 100 g / m 2 and which is doubled

  flame by a layer of soft foam of an ester, pos-

  sedant a thickness of 2 mm. A glue is deposited using a doctor blade formed of acrylate, brought in the form of foam air, a weight of 300 g / l over a thickness of 300 gm. In the substrate, polyamide flocks are flocked.

  of 1.7 dtex, cut to a length of 0.7 mm.

  After flocking, the flocked web article is removed, the fibers forming the excess flocs and calendering is carried out while the glue layer is wet. The flocked web article is dried in a drying channel, then fixed with additional heat treatment and then the excess flocs are removed and wound. The surface is comparable to a very fine piqué of wool, has a silky and supple appearance. The band is bi-elastic

  transparent in the air, light and flexible.

  Example 2: Flocked sheet goods are analogous to

  case of example 1. After calendering, a gauze is made

  frage of the tablecloth article in the wet state. The effects of

  embossing can be identified by comparison with an

  mure of fabric. The silky reflection is interrupted by the dif-

  fers embossing planes.On gets a solid appearance and relief.

Example 3

  The flocked sheet articles are identical to those of Example 1. In place of the flexible and thin foam formed of an ester, the fabric is fixed by doubling to

  the flame a soft foam of an ester with a thick

  15.5 mm. The surface is fine and has a silky gloss. The web article is flexible, breathable, bi-elastic and provides acoustic insulation and

thermal insulation.

Example 4

  The substrate consists of a flexible sheet of PVC with a thickness of 2mm, on which is affixed to the doctor blade a layer of glue. The flocs are formed by a polyamide of 1.7 dtex, cut to a length of 0.7 mm. The

  flocking is performed electrostatically.

  The superfluous flocs are removed from the nap-

  pe flocked, we begin to lightly dry, then

  the calendering and embossing of the article is carried out. In-

  The final drying of the flocked web article is then carried out, it is fixed, it is cleaned and it is obtained in the form of a flexible article in strips having the fine aspect and

  decoration of a flannel, with a structure in the form of

mature in the direction of the fabric.

  Figure 1 schematically shows an installation

  lation to produce a flocked article in the

  which reference 1 designates the support or transmission cylinders

  port for a substrate 2. Reference 3 designates a doctor blade

  by means of which a glue or glue is deposited

  mant foam in the air 4 on the surface of the substrate. The reference

  electrostatic mode are flocked in the glue layer.

the flock layer 6.

  Reference 9 designates a shell. The flocked article 8 is driven through the gap between the rolls of the shell and is then

  my. Next, that the calendering is done while the

  layer of glue is in the wet state, in the semi-humid state

  from or in the starting drying state, the surface appearance therefore has a silky gloss or is matte, with a fine or very fine uniform sense of the fabric. The surface is

  smooth. The flocked calendered article 10 passes through

  following a drying zone 11, a drying and fixing zone 13, installed downstream, and then cleaned by means of

  of a cleaning device 15 and is wound. The rou-

water is designated 16.

  Figure 2 of the drawing schematically shows another installation for making a flocked web article. This installation is in principle identical to that of Figure 1, but further comprises an embossing cylinder 17. The embossing function can

  also be realized by means of an embossing pattern.

  The calendered flocked article is embossed with a predetermined surface structure as a function of the subsequent, but selectable, purpose of use. If the embossing takes place while the adhesive layer is still in the wet state, in the semi-wet state or in the light drying state, the structure can be fine to very fine or can be made from in order to be noticeable

  in the case of refraction of the light in the finished state.

  A variant can be used by providing a cylinder of

  drying 19 upstream of the calendering device (see FIG.

  3) or a drying zone 21 (see FIG. 4) between the calendering device and the embossing device. The

  calendering or embossing can be achieved when the

  The flocked web article is in the initial drying state or in the predried state. These superficial structures are

  visible in a moderately to strongly charged manner.

  These structures can be realized in a pre-

  with a rustic appearance and are also well

touch sensitive.

  Both the calendered flat flocked tablecloths and the calendered and embossed flocked flexible web articles according to the invention have a surface having a fineness and, in the case of embossing,

  structural finesse, which has never been

  held until then. The fineness, the direction of the fabric and the structure of these surfaces do not vary even in the case of a surface friction. They are also extremely resistant to wear. In addition touch

is very sweet and pleasant.
