  • the twist coefficient of each cotton spun yarn was controlled in the range of 4.0 to 4.8 so that the strength of the warp was higher than that of the weft.
  • the Raschel knitting machine is used as in the above Example 1, and the lap net having the knitting structure shown in FIG. 3 (two adjacent independent chain knits are two wefts). Connected net) was organized.
  • the knitting density of the lap net knitted in Example 2 is 2 courses/2.54 cm, and chain stitches (independent chain knitting) that are continuous in the length direction of the knitted fabric and adjacent chain stitches (independent chain knitting) was about 1.7 cm (about 1 inch). Further, the interval (Y2 in FIG. 4) between the connecting points in one chain stitch (independent chain stitch) was 1.3 cm (about 2/3 inch).
  • the characteristics of the lap net made of a cellulosic fiber that solves the problems of the conventional wrap net made of the slit yarn of the general-purpose synthetic resin are maintained, and the cut wrap net is used. It is possible to provide a wrapping net which does not get entangled in the unwinding roll of the wrapping machine without converging the end of the wrapping.

Abstract

L'invention concerne un filet d'emballage qui maintient les caractéristiques d'un filet d'emballage constitué d'une fibre cellulosique et qui élimine les inconvénients des filets d'emballage classiques faits de fils de film coupé en résine synthétique à usage général, et pour lequel les extrémités de rouleau coupées du filet d'emballage ne se regroupent pas ni ne s'emmêlent sur le rouleau d'enroulement d'une machine d'emballage. La présente invention est caractérisée en ce qu'elle est composée d'un tissu tricoté obtenu par formation de plusieurs points de chaînette indépendants dans lesquels des fils de chaîne constitués de fibres cellulosiques et disposés dans des rangées parallèles dans le sens de la longueur du tissu sont chacun réalisés en boucles continues dans le sens de la longueur du tissu, et par liaison de chaque boucle d'un point de chaînette indépendant avec une autre boucle d'un autre point de chaînette indépendant par l'intermédiaire d'un fil de chaîne fait à partir d'un tissu cellulosique ; et en ce qu'elle obtient chacun des multiples points de chaînette indépendants en formant en alternance une ou plusieurs boucles fermées et une ou plusieurs boucles ouvertes.
