Definitions

  • the present invention relates generally to a printed loop fabric with improved graphic visibility and clarity which may be used as the female portion of a mechanical closure system.
  • the loop fabric is generally comprised of a knit fabric. More specifically, the fabric is comprised of a warp knit, weft inserted lap side loop pile fabric having adjacent loops in each wale alternate from one direction to the other.
  • the methods employed to create the printed loop fabric having improved graphic visibility and clarity also provide a printed loop fabric that exhibits sufficient hook to loop engagement strength desired for the fabric's end use as the female portion of a mechanical closure system.
  • One method of creating the printed loop fabric includes coating the backside of the loop fabric with a thermoplastic material and then printing the face side of the coated fabric. This method generally eliminates the need to rely upon the "see through” characteristics of the fabric, adhesive, or film comprising the product, in order to see the printed image and results in a printed loop fabric with improved graphic visibility and clarity.
  • the printed loop fabric may be achieved by applying a thermoplastic material to the backside of the loop fabric and printing on the thermoplastic material.
  • This method of obtaining a printed loop fabric relies upon the see through characteristics of the fabric. Accordingly, it may be preferable to use a loop fabric comprised of low loops which provides increased open space between the yarns of fabric. The resulting fabric exhibits improved graphic visibility and clarity of the printed image applied to the backside of the fabric.
  • the printed loop fabric may also be produced by applying a thermoplastic material to the backside of a loop fabric comprised of low loops and laminating a pre-printed film to the thermoplastic material. Again, due to the increased open space between the yarns of the low loop fabric, the printed low loop fabric having a pre-printed film laminated to the thermoplastic material also exhibits improved graphic visibility and clarity when compared with other similarly constructed fabrics.
  • the printed loop fabric of the present invention may be utilized as part of the mechanical closure system for disposable diaper products. It has been generally established that consumer market demands a product printed with patterns, characters, or words for the purpose of landing zone identification, which provides a locator for the hook portion of the closure system, and brand recognition. Accordingly, market advantage may be gained in offering a loop product with the best print visibility and clarity. Currently, most loop fabrics created for this purpose are laminated to pre-printed films and have less print clarity and graphic visibility than the printed loop fabric of the present invention. The current invention discloses a printed loop fabric with improved graphic visibility and clarity and sufficient hook to loop engagement strength, which are important attributes for the fabric's end use as the female portion of a mechanical closure system.
  • the product may reduce the length of the supply chain by eliminating the need for a separate film manufacturer and printer because the printing may be applied directly to the loop fabric without the need for a pre-printed film.
  • the fabric of the present invention may allow for the retention of an unprinted inventory of loop fabric which may be printed on a "print to order" basis, thus, reducing industry run size requirements.
  • FIG. 1 is a schematic representation of the hook fasteners in relation to the printed loop fabric.
  • FIG. 2 is the top view of the lap (technical back) side of the printed loop fabric.
  • FIG. 3 is a point diagram of the action of the guide bars of the knitting machine for one embodiment of the printed loop fabric.
  • FIG. 4 is a point diagram of the action of the guide bars of the knitting machine for another embodiment of the printed loop fabric.
  • FIG. 5 is a point diagram of the action of the guide bars of the knitting machine for the printed low loop fabric.
  • FIG. 6 is a view similar to FIG. 1 showing the printed loop fabric with a thermoplastic material on the backside of the fabric.
  • FIG. 7 is a schematic view of the method for applying a thermoplastic material to the backside of the printed loop fabric.

  • Sample 1 was the control sample, which was not exposed to the high friction roll. Samples 2 through 4 were exposed to the high friction roll, and the direction of the high friction roll was opposite to the direction of the fabric flow through the machine.
  • a printed loop fabric which can readily function as the female member of a hook and loop connection and which exhibits improved clarity and visibility of a printed image when compared with other similarly constructed fabrics.
  • the process of flexographic printing the face of the fabric composite eliminates the need to rely upon the "see through" characteristics of the fabric, adhesive, or film comprising the product, in order to see the printed image, thereby providing improved clarity and visibility of the printed image. Because of the increased openness between the yarns comprising the low loop fabric, the process of printing on the thermoplastic material on the backside of the fabric results in a printed loop fabric having improved graphic clarity and visibility.
  • the printed loop fabric does not readily tear due to the weft inserted yarn that provides stability in the weft direction of the fabric, and backcoating the fabric with a thermoplastic material provides stability to the fabric and does not tie down all of the loops of the fabric thereby preventing the destruction of the retention power or the ease of releasement of the hook and loop connector. Additionally, the printed loop fabric is relatively inexpensive, simple, and straight forward to manufacture.

Abstract

L'invention concerne, d'une manière générale, un tissu bouclé imprimé présentant des visibilité et clarté graphiques améliorées et pouvant être utilisé comme partie femelle d'un système de fermeture mécanique. Le tissu bouclé comprend en général un tissu maille, et plus précisément, un tissu à mailles jetées et à insertion de trames. Un procédé de création du tissu bouclé imprimé consiste à enduire le côté arrière du tissu bouclé, au moyen d'un matériau thermoplastique, puis à imprimer le côté avant du tissu enduit. Dans un autre mode de réalisation, le tissu bouclé imprimé peut être obtenu par application d'un matériau thermoplastique sur le côté arrière du tissu bouclé et par impression sur le matériau thermoplastique. Le tissu bouclé imprimé peut également être produit par application d'un matériau thermoplastique sur le côté arrière d'un tissu à boucles faibles et par stratification d'un film imprimé au préalable sur le matériau thermoplastique. Le tissu peut être fabriqué sans réduire la résistance de la prise des boucles sur les crochets.
