Definitions

  • the present invention relates to printable natural fiber based fabrics and garments. It further relates to a novel method for printing on cotton and other natural fiber based fabrics.
  • Printing on fabrics is one of the most important methods of decoration as well as value addition to the fabrics and garments.
  • roller printing, screen printing, transfer printing etc. When it comes to multi colour photographic printing few techniques such as transfer printing, roller printing and ink jet printing techniques are widely being used.
  • Ink jet printing process is a type of computer printing that directly creates the image on the fabric by propelling droplets of ink.
  • the transfer printing employs a flexible, non-textile substrate as an intermediary.
  • the mirrored image is printed on the substrate and subsequently it gets transferred on to the fabric.
  • One such process of transfer printing is called sublimation printing. This is because the dye which is used for the sublimation printing on the substrate makes the transition between the solid and gaseous state without going through a liquid state.
  • the present invention overcomes the problems, as is seen from the prior art, namely the life of the printing and its viability of printing on the natural fibre based fabrics. It is achieved by introducing a novel approach called Modularly Adaptable Synthetic yarn based Embroidery (MASE). By introducing the MASE technique, it introduces an adequate and efficient substrate for printing multi colour photographic like printing possible on the natural fibre based fabrics (NF fabrics). Furthermore the printing lasts longer which was otherwise almost impossible. Using novel MASE substrates for printing on the NF fabrics also works out to be cost effective in comparison with other techniques found in the prior arts.

  • FIG 12 illustrates the transfer paper 100 as required for another requirement
  • FIG 13 illustrates the printed fabric in accordance with the other requirement.
  • NF fabrics include cotton, jute, hemp and like fibres.
  • the NF fabric also includes any combination of natural fibre rich fabrics wherein the natural fibre content is substantial.
  • holder rings known as hoops Basing on the contour of the picture to be printed, holder rings known as hoops are prepared for the embroidery.
  • synthetic yarns By fixing on to the holder rings, using synthetic yarns, embroidery is done on to the fabric.
  • the synthetic yarns are so selected that it provides for efficient printing and also provides for longer life.
  • polyester yarn is one such synthetic yarn that provides for lasting prints.
  • the density of the embroidery is optimised basing on the pictures to be printed.
  • the density of the embroidery means the degree of sparseness of the embroidery. If the sparseness is more the appeal and effectiveness of true to life reprints reduces. On the other hand, if the sparseness is less, the embroidery is denser and produces good appeal and better reproduction.
  • the present invention is outlined as a flow chart in FIG 1.
  • the flow chart illustrates one embodiment of the process.
  • the fabric to be printed is prepared according to the print to be reproduced. It involves creation of templates basing on the contour of the required print to be reproduced, preparation of holder rings, preparation of the reverse print on the transfer paper also known as sublimation paper printing and other related works.
  • the fabric is held with the help of holder rings and the embroidery is made in accordance with the layout and contours called MASE.
  • the embroidery may be manual and can also be automated.
  • the synthetic yarns used for the embroidery is selected from a group of yarns namely polyester, nylon, rayon, aramids, acrylics, cholorofibres, elasthanes, polyolefins, and others.
  • the synthetic yarns are sized and seasoned prior to embroidery to avoid any shrinkage and other like defects during its service as garments after printing.
  • the embroidered fabric is printed using dispersible dyes using processes like sublimation.
  • Sublimation process involves transfer of already printed dyes from the transfer paper to the other substrate.
  • sublimation means the dyes on the transfer paper gets transferred to the other substrate without the intermittent liquid phase.
  • transfer paper The already prepared paper with reverse print called transfer paper, as explained in the step 10, is placed over the MASE substrate as per the layout and the contour of the print required.
  • a hot press is used to transfer the print on the transfer paper to the MASE substrate.
  • the hot press consist of two platens; one being stationary and the other being movable.
  • the fabric with the transfer paper is placed in the stationary platen of the hot press.
  • the platens of the hot press have the provisions for heating as well as applying pressure during the transfer process. Applying heat and pressure the print from the transfer paper gets transferred to the MASE substrate. The temperature and pressure required to transfer the print depends on the print to be reproduced. It is optimized empirically.
  • the transfer printing can also be made using roller press also known as continuous feed hot press.
  • This roller press can be used for continuous printing on running fabrics as well as for discrete printing on pieces of fabrics.
  • the Roller press employs rotatable rollers. The assemblage of the MASE embedded fabric and the transfer paper is made to pass through the heated rollers. After the transfer process i.e. printing on the MASE, the fabric is removed from the press and allowed to cool at the room temperature for further processing like making required garments and like.

Abstract

La présente invention concerne des tissus et des vêtements à base de fibres naturelles imprimables. L'invention concerne en outre un procédé nouveau d'impression sur du coton et d'autres tissus à base de fibres naturelles. La présente invention surmonte les problèmes rencontrés dans l'état de la technique, à savoir la durée de vie de l'impression et sa viabilité d'impression sur des tissus à base de fibres naturelles. La solution est obtenue par l'adoption d'une approche nouvelle appelée broderie à base de fil synthétique à adaptabilité modulaire (MASE). La technique MASE adoptée utilise un substrat adéquat et efficace pour imprimer une impression de type photographique multicolore sur des tissus à base de fibres naturelles (tissus NF). De plus, l'impression dure plus longtemps, ce qui était autrement quasiment impossible. L'utilisation de substrats MASE nouveaux pour l'impression sur les tissus NF s'avère également économique par rapport à d'autres techniques.
