Abstract

La présente invention concerne un procédé de fabrication de fil réfléchissant, et un fil réfléchissant fabriqué selon ce procédé. Le fil réfléchissant de la présente invention présente une surface molle et conserve une brillance réfléchissante, par application d'un film transparent sur les parties supérieures et inférieures d'un film réfléchissant, par effilochage du film réfléchissant, par enroulement en spirale d'un film de couverture effiloché autour de la surface du film réfléchissant, et par fabrication du film réfléchissant effiloché. La présente invention comporte quatre étapes générales, à savoir: une étape de préparation (S1) par laquelle on prépare, d'une part un film réfléchissant (10) dans lequel sont incluses des billes de verre (11), et d'autre part un film transparent (20) et un film de couverture, tous deux en résine synthétique; une étape d'application (S2) par laquelle on applique le film transparent (20) sur les surfaces supérieure et inférieure du film réfléchissant préparé (10); une étape d'effilochage (S3) consistant à effilocher dans le sens de la longueur le film appliqué; et une étape de couverture (S4) par laquelle on enroule en spirale le film de couverture (30) effiloché, de façon à recouvrir totalement le pourtour extérieur du fil effiloché. Le fil fabriqué selon le procédé de l'invention évite que la brillance de réflexion du film réfléchissant ne se dégrade, et lui conserve sa brillance de réflexion, parce que, d'une part le film transparent est appliqué sur les surfaces supérieure et inférieure du film réfléchissant, et d'autre part le film de couverture enroulé sur le pourtour extérieur du film est en matière transparente. En outre, l'invention se distingue, d'abord en ce qu'elle convient à des utilisations multiples et notamment à la couture, à la broderie, et analogue, étant donné que la partie effilochée du film réfléchissant obtenu par enroulement du film de couverture sur le pourtour extérieur du film réfléchissant est traité dans une forme semblable à un cercle, et ensuite en ce qu'elle améliore la productivité en faisant baisser la fréquence de remplacement de l'aiguille en évitant l'abrasion du chas d'aiguille grâce au polissage de la surface du fil réfléchissant. De plus, la présente invention améliore la solidité et facilite la couture en renforçant l'ensemble du pourtour extérieur du film réfléchissant grâce à l'utilisation d'une résine synthétique pour la fabrication du film transparent et du film de couverture.
