Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for knitting a cylindrical pile warp knitted fabric.

[Conventional technology]

Conventionally, the technology to create pile on one side of a cylindrical warp knitted fabric was
The present applicant has proposed in Utility Model Application No. 1983-2336, and the manufacturing method of the cylindrical pile warp knitted fabric in this proposal includes a course in which the pile yarns to be piled are looped at the same time as the ground warp yarns, and a loop loop. By providing a non-loop course in which no loops occur and actively feeding the pile yarn, the pile yarn is made to bulge out from the surface of the base fabric in the non-loop course.

[Problem that the invention seeks to solve]

However, when forming piles in the above manufacturing method, there is no problem with relatively short piles.

When the pile length becomes long, it is difficult for the formed pile to have a uniform length.

The present invention aims to eliminate the above-mentioned drawbacks and provide a knitting method that can easily knit a cylindrical pile warp knitted fabric with uniform pile length.

[Means to solve the problem]

The method for knitting a cylindrical pile warp knitted fabric according to the present invention uses a double-row warp knitting machine equipped with a front needle row and a rear needle row, and uses a front base fabric in the front needle row and a rear base fabric in the rear needle row. A method for knitting a cylindrical warp knitted fabric by knitting each of the following knittings and connecting knitting of each end of each of the two base fabrics, and for making a pile appear inside the cylindrical warp knitted fabric, wherein the pile on the front side When applying the yarn reed to the rear needle row and the rear pile yarn reed to the front needle row, the pile yarn reed is applied to the holding yarn provided in the knitting direction between the two pile yarn reeds. The knitting method is such that the feeding pile yarns are crossed and the holding yarns are pulled together by the front and rear pile yarns. [Function] The pile yarns are wrapped around the holding yarns arranged between the front and rear needle rows. As a result, it acts like a pin needle in a single row warp knitting machine, and all the pile yarns that are stretched over each other have a constant distance from the base fabric, resulting in a cylindrical pile warp knitted fabric with uniform pile length.

〔Example〕

Next, the knitting method of the present invention will be explained based on one drawing.

FIG. 1 is a schematic side view of the main knitting parts of a double-row warp knitting machine during knitting of a cylindrical pile warp knitted fabric, in which 1 to 8 are ground reeds, 9 is a knitting needle of the front needle row F, and 10 are the knitting needles of rear needle row B,
The ground reeds 1 and 2 are for forming the front base fabric 11, and the ground threads 13 and 14 are passed through the ground reeds 1 and 2, and the pile yarn 15 is threaded through the ground reeds 3. The binding thread 16 is attached to the reed 4, and the ground reed 5
The holding thread 17 is attached to the ground reed 6, the pile thread 18 is attached to the ground reed 7,
゜8 is for forming the rear base fabric 12;
8, the base threads 19 and 20 are threaded according to the number of threads to be threaded, which will be described later. 21 is a front trick plate, and 22 is a rear trick plate.

Next, the knitting will be explained based on the knitting organization chart shown in FIG.

As shown in the threading position at the bottom of Figure 2, the ground yarn 13 is packed in the number of yarns corresponding to the knitting needles corresponding to the knitting width corresponding to the length corresponding to half the circumference of the desired cylindrical pile warp knitted fabric. The ground thread 1 is threaded through the ground reed 1 at the same time, and threaded at the ground reed 2 at the same time.
The front base fabric 11 is knitted using the front knitting needle row F by performing insertion knitting between two needles on the stitch row knitted with the 1×1 tricot structure according to No. 4. Also, using the rear knitting needle row B, for the stitch row knitted with a 1×1 tricot structure using the ground yarn 19 threaded through the ground reed 7 in the general direction, the stitch row is knitted with the ground thread 2o threaded into the general direction through the ground reed 8. Rear base fabric 12 by inserting stitches between two stitches
organize. On the other hand, in the fabric reed 4, which is made by passing one binding yarn 16 through the knitting needles at both ends of the knitting width, stitches are formed alternately by the front and rear knitting needles 9° and 10 at opposite ends. As the binding yarn 16, an elastic yarn or the like is used, and as shown in FIG. 3, the wale Wf and the wale wb at both ends of the front base fabric 11 and the rear base fabric 12 are pulled together after knitting to form a cylindrical shape. be. Then, when the pile yarn 15 reed 3 on the front side is applied to the rear needle row B in the B□ course and again to the rear needle row B in the next B2 course, the pile yarn reed 3 and the pile yarn reed 6, the holding yarn 17 is formed by threading the number of yarns through the base reed 5 in the knitting direction in a number corresponding to the number of pile yarns. However, by crossing the holding thread 17, the pile Pf appears on the front base fabric 11 as a wale direction pile continuous in the wale direction.

At the same time, when the rear side pile thread 18 ground reed 6 is applied to the front needle row F in the F1 course and again to the front needle row F in the next F2 course, it is similarly applied to the holding thread 17. By crossing, the pile PB is made to appear on the rear base fabric 12 as a continuous pile in the wale direction.

At this time, when the front pile yarn 15 and the rear pile yarn 18 are applied to knitting needles on opposite sides to intersect with the retaining yarn 17, the retaining yarn 17 is created in a knitting structure in which the retaining yarn 17 is alternately pulled in opposite directions. do.

At this time, it is necessary to keep the yarn tension of the knitting yarn as the holding yarn 17 high; if it is weak, the pile length tends to be inconsistent and uneven, and it takes time to pull it out.

In the above embodiments, a normal fiber thread is used as the holding thread 17, but instead of this, a water-soluble thread that dissolves in water at a certain temperature or higher or a soluble thread that melts in a specific solution is used. By functioning as a thread, the trouble of removing the stitches can be saved.

In addition, in the above example knitting, pile yarn 15.18
Since both act on the same knitting ale, the pile is continuous in the wale direction, but of course, as shown in Fig. 4, after crossing the pile yarn from one wale to the holding yarn 17, the same - Inter-wale pile SPf, inter-wale pile SP by spanning over adjacent wales in the base fabric
b, or it is also possible to make the pile yarn intersect with two holding yarns 17, thereby forming a dense pile.

The result obtained by the above organization is as shown in Figure 5.
Although it is in a flat state, when the piles are connected by holding threads, by removing them, a cylindrical pile warp knitted fabric with the piles bulging out on the inner surface as shown in Figure 6 is created. It is used by cutting it to the required length depending on the purpose, but by turning it over as shown in Fig. 7, the pile bulges out on the outer surface, which can be used for other purposes.

〔Effect of the invention〕

As described above, in knitting a 1-cylindrical pile warp knitted fabric, the present invention involves connecting the face ends of the front base fabric formed by the front needle row and the rear base fabric formed by the rear needle row with a connecting thread to form a cylindrical shape. Since the pile is formed by knitting the front pile yarn and the rear pile yarn in a state where they are drawn to each other on the holding yarn provided in the knitting direction between the pile yarn reeds, it is possible to form a pile even with long pile lengths. The height of the pile is regulated by the holding thread, so
The result is a cylindrical pile warp knitted fabric with uniform pile length.
