Abstract

PURPOSE:To obtain an artificial grass leaf in which wide rachises or many rachises densely project by passing pile yarn through two crochet stitch loops of ground yarn respectively from the left to right or the right to left in one direction and forming the rachises. CONSTITUTION:Ground yarn 13 is used to alternately form S-shaped stitches 14 and Z-shaped stitches 15 and chain stitch loops 11 and crochet 12 loops are formed. One chain stitch loop 11 is engaged with the other crochet stitch loop 12 to construct the stem core 16 connected in the longitudinal direction and rachises 18 are projected from the stem core 16 in the form of tufts so as to pass the two crochet loops 12 and 12' reversed in the longitudinal direction thereof while bending pile yarn 17 in the form of U by changing the direction left and right. Thereby, the pile yarn can be formed into a bound thick yarn bundle in which wide tapes or many yarns are bound.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to sphagnum moss for gardening, aquatic plants for aquariums, seaweed for artificial fish reefs,
This invention relates to artificial grass leaves used for displays and the like.

(Prior art) The present inventor invented artificial grass and leaves, and
(Disclosed in JP-A-60-151352).

The artificial grass leaves according to the above-mentioned invention disclosed by the present inventor are made using a warp knitting machine, and the stem core, which is unified in the length direction, is bent back and forth by alternating the curvature direction into an S-shape and a bi-shape. The chain loops and hook loops of the S-shaped stitches and second-shaped stitches of the ground yarn that are subsequently formed are engaged to form a chain, and the knotted loop of the pile yarn is formed along the chain loop of the ground yarn. It is constructed by inserting both ends into the chain loops of the next ground thread, and the leaf axis protrudes from the stem core.

[Problem that the invention seeks to solve]

In the above-mentioned prior invention, a knotted loop of pile yarn is formed along the chained loop of the ground yarn, and both ends of the knotted loop are passed through the next chained loop of the ground yarn to form a leaf axis. Therefore, even if you try to use a thick tape or a wide tape with many threads tied together for the pile threads that make up the leaf axis, the warp knitting machine will not form knotted loops that follow the chain loops of the thin ground threads. It is difficult to pull out the thread by slipping it through the chain loops of the thread.

Therefore, the thickness of the pearl yarn used is limited, and it is not possible to obtain artificial grass leaves with many densely protruding leaf axes or artificial grass leaves with wide leaf axes protruding.

[Purpose of the invention]

Therefore, an object of the present invention is to obtain an artificial grass leaf in which a wide leaf axis or a large number of leaf axes protrude closely.

[Structure of the invention]

That is, in the artificial grass blade 19 according to the present invention, the ground yarn 13 alternately changes the curve direction in an S shape and a Z shape, and forms a chain loop 11 with the opening facing the front while being curved at the top and bottom of each. , S-shaped stitches 14 and Z-shaped stitches 15 forming hooked loops 12 with openings facing the side are alternately formed on the other side, and the alternating one chain loop 11 and the other hooked loop 12 are formed alternately. The pile yarn 11 connects at least two barbed loops 12 and 12' which extend in the longitudinal direction W in a U-shape. The leaf axis 18 is characterized by bending, changing direction from side to side, passing through the stem core 16, and protruding from the stem core 16 in the shape of a cluster.

As disclosed in the prior invention, the stem core 16 has hook loops 12, 12', 12'', etc. of the stitches 14, 15, 14', . It is also possible to knit by changing the direction of the weft thread 20 in a zigzag pattern to the left and right.
1 and 2), or several rows of stitches 14 and 14' (15 and 151) knitted in parallel with several ground yarns 13 and 13'
) can also form the stem core 16 in the form of a tape (FIG. 2).

The number of hooked loops 12 that the pile yarn 17 passes through is not particularly limited as long as it is 2 or more, but it is generally 5 to 6 (il is the limit, and if the pile yarn has an odd number of hooked loops 12 that it passes through, both ends are at the stem core. Leaf axis divided into 16 left and right sides 1g/181
If the number is even, a pair of leaf axes 18 and 1g-1 will be formed on one side of the stem core 16 (Figs. 3 and 4). .

Of course, this is a matter of specializing the way a single pile yarn dives, and when two pile yarns dive from the left and right sides of the hook loop 12, the leaf axis 18 is formed symmetrically to the stem core 16. be done.

FIGS. 1 to 4 illustrate how the pile yarn 17 goes under. When the pile yarn 17 goes through the three front and rear hooked loops 12, the pile yarn 17 forms an S or two curved shape. and Fig. 2), if you can support the two hooked loops 12 in the front and back, make a U-shape 1@
Figure 1) - 1 front and back 4 hooked loops 12
In order to pass through the area, there will be 3 fi 1 turns in a W shape (Figure 4).

〔Effect of the invention〕

In the present invention, the pile yarn 17 does not pass both ends of a knotted loop formed along a chain loop of the ground yarn through another chain loop of the ground yarn to form a leaf axis. The leaf axis 18 is formed by passing through the two hooked loops 12 and 12' from left to right or from right to left, respectively, and in the process of forming it on the warp knitting machine, it simply passes through the sides of the knitting needles. Since the knitting is done simply by passing the knitting needle between the chain loops of the ground yarn, there is no problem in knitting even if a thick tape made by binding many yarns or a wide tape is used as the pile yarn. ,
Therefore, it is possible to obtain an artificial grass leaf in which a wide leaf axis or a large number of leaf axes are densely protruded, and therefore, by using pile yarns of various forms, a novel artificial grass leaf with a change in the shape of the leaf axis lO can be obtained. I can do it.

The leaf axis 18 does not pass straight through the hook-like loops 12 and is locked to the stem core 16, but instead passes through the hook-like loops 12 of 2 (i1 or more) in the left-right direction and is locked. Therefore, the pile threads 17 will not come off from the hook loop 12 and fall off from the stem core 16 during use, and if the pile yarn 17 is made thicker, it will receive stronger tightening force from the hook loop 12, so the leaf axis 18 will fall off more and more. Therefore, durable artificial grass leaves 19 can be obtained.

Claims (1)

[Claims] The base yarn 13 alternately changes the direction of curvature into an S-shape and a Z-shape, forming a chain loop 11 with the opening facing the front on one side and the opening facing the side on the other side. S-shaped stitch 14 and Z-shaped stitch 15 forming hook loop 12
are formed alternately, and one of the alternating chain loops 11
and the other hooked loop 12 are engaged to form a stem core 16 that continues in a chain shape in the length direction W, and at least two hooked loops 12 and 12' are arranged in front and behind each other in the length direction W of the stem core 16. This artificial grass leaf is characterized in that the pile threads 11 are bent in a U shape, changed direction from side to side, and pass through, so that the leaf axis 18 protrudes from the stem core 16 in a tuft-like shape.
