Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for producing a double-sided raised warp knitted fabric.

[Conventional technology]

Conventionally, in manufacturing a double-sided nap warp knitted fabric, a nap portion made of a pile yarn is provided on one side of a base fabric, and a suitable pile yarn is drawn out to the other side by a pulling thread, thereby obtaining a double-sided nap warp knitted fabric. The method of manufacturing
No. 199114.

In this method of manufacturing a raised knitted fabric, a double Raschel machine having at least seven rows of guide bars is used,
The front base cloth and the rear base cloth composed of the chain yarn and the insertion yarn are connected and knitted by the pile yarns supplied by the single row of the guide bars, and the needles are attached to the guide bars arranged at the forefront and rearmost portions. After knitting a double-sided pile warp knitted fabric by passing the same number of yarns as the number of chain yarns corresponding to the number of yarns and detour knitting the pile yarns for each suitable course, the pile yarns between both base fabrics The center yarn is cut in the knitting direction, then the yarns inserted into the respective base fabrics are pulled out almost vertically, the appropriate pile yarns on one side are pulled out on the other side, and the double-sided napped warp knitted fabric is obtained. Has formed.

[Problems to be solved by the invention]

Such a double-sided raised warp knitted fabric is usually used for a blanket.However, in the above-described yarn drawing step, the same number of yarns as the number of chain yarns constituting the wale of the base fabric are used.
In the back pile unwinder shown in JP-B-48-36716, the arrangement density of the thread removal disk provided between the fabric before thread removal and the fabric winding part after thread removal is the same as the wale density of the warp knitted fabric. Therefore, the gap between the discs is narrow, and when a knot or the like of the drawn thread passes at the time of thread drawing, depending on the thickness and type of the thread, the knot may be wound up without passing through the disc. Problems such as thread breakage and winding around the roller due to thread breakage occurred.

An object of the present invention is to eliminate the inconvenience at the time of the yarn removing step, and to manufacture a double-sided napped warp knitted fabric by a novel method that takes into consideration the way of entanglement and arrangement of the extracted yarn with the ground structure at the time of knitting.

[Means for solving the problem]

In the method for producing a double-sided nap warp knitted fabric according to the present invention, half of the drawn yarn is arranged for every other needle with respect to the chain yarn corresponding to the number of the needles, and the adjacent yarns are sequentially stretched every one to several courses. For each pile yarn to be stitch-formed, the center of a double-sided pile warp knitted fabric knitted while alternately tangling each one of the above-mentioned yarns to an adjacent needle in a yarn-drawing course, and then using a yarn-drawing machine. A desired pile is drawn out from one side of the napping base fabric to the other side to form a double-sided napping.

[Action]

Since the number of yarns to be removed is half of the number of chain yarns, the yarn removal disk at the time of yarn removal may be set to a half gauge of the wale by the chain yarns. In other words, it passes between the discs having extra dimensions, so that even if a large portion of the knot passes between the discs, it does not get caught or jammed.
