Definitions

  • a first embodiment method for forming a hook fastener portion is schematically illustrated in Fig. 1.
  • the method includes first extruding a strip 50 shown in Fig. 2 of thermoplastic resin from an extruder 51 through a die 52 having an opening cut, for example, by electron discharge machining, shaped to form the strip 50 with a base 53 and elongate spaced ribs 54 projecting above an upper surface of the base layer 53 that have the cross sectional shape of the hook portions or members to be formed.
  • the cutter 58 can cut using any conventional means such as reciprocating or rotating blades, lasers, or water jets, however preferably it cuts using blades oriented at an angle of about 60 to 80 degrees with respect to length of the ribs 54.
  • the base 53 of the strip 50 is longitudinally stretched at a stretch ratio of at least 2 to 1, and preferably at a stretch ratio of about 4 to 1, preferably between a first pair of nip rollers 60 and 61 and a second pair of nip rollers 62 and 63 driven at different surface speeds.
  • the strip 50 can also be transversely stretched to provide biaxial orientation to the base 53.
  • the sample was then placed in a 135 degree peel jig.
  • the jig was placed into the bottom jaw of an InstronTM Model 1122 tensile tester.
  • the loose end of the paper leader was placed in the upper jaw of the tensile tester.
  • a crosshead speed of 30.5 cm per minute and a chart recorder set at a chart speed of 50.8 cm per minute was used to record the peel force as the hook strip was peeled from the loop material at a constant angle of 135 degrees.
  • An average of the four highest peaks was recorded in grams.
  • the force required to remove the mechanical fastener strip from the loop material was reported in grams/2.54 cm- width. A minimum of 10 tests were run and averaged for each hook and loop combination.
  • Example and comparative example hook materials were measured using X-ray diffraction techniques. Data was collected using a

Abstract

La présente invention concerne un procédé pour produire une partie en saillie ou un système d'attache polymère unitaire comprenant un support mince résistant et souple, ainsi qu'une pluralité d'éléments de crochet minces espacés, qui font saillie de la surface supérieure du support unitaire. Ce procédé consiste à extruder une résine thermoplastique à travers un plateau matrice conçu pour former une couche de base et des crêtes, des nervures ou des éléments de crochet faisant saillie de la surface de la couche de base. Lorsque la matrice forme les crêtes ou nervures espacées, la forme de la section transversale des éléments de crochet est produite par le plateau matrice et l'épaisseur initiale des éléments de crochet est obtenue par découpe transversale des crêtes à des emplacements espacés sur leur longueur, afin de former des parties de découpe discrètes des crêtes. Un étirage longitudinal ultérieur de la couche de support (dans la direction des crêtes dans la direction de la machine) permet de séparer ces parties de découpe des crêtes, ces parties de découpe formant ensuite des éléments de crochet séparés. Les éléments de crochet extrudés ou les éléments de crochet à nervure découpée sont ensuite soumis à un traitement thermique, ce qui implique le retrait d'au moins une partie d'au moins l'épaisseur de la partie de tête de crochet de 5 à 90 %, de préférence de 30 à 90 %.
