Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a river lace-like lace fabric with good stitching, fineness, and high class, and in particular, a raschel knitting fabric that can be knitted in large quantities in a single time. It is related to the lace area.

[Prior art 1] As is well known, lace fabric is made by twisting, combining, or intertwining threads to create an openwork pattern, and there are two types of lace: handmade lace produced by hand and machine lace produced by various machines. It is broadly classified. Machine lace is
It is superior to handmade lace in that lace fabric of uniform quality can be produced in large quantities, and can be provided at a relatively low cost, and its research and development has progressed at a rapid pace.

Among these mechanical laces, Raschel lace knitted by a Raschel machine is economically extremely advantageous in that a large amount of lace can be produced in a single hour. However, the Raschel lace knitted by this Raschel machine has a warp in the form of a loop, and the back thread is passed through the loop, as shown in Figure 2.
Back thread passed between adjacent warp threads (12) and (12)
13), (l4) are adjacent warps (12), (l2)
This is due to the weaving that moves back and forth between the stitches, and has the drawback of poor stitching and lack of denseness in the horizontal sections (15) and (16) that are stitched back and forth.

On the other hand, river lace knitted by a river lace machine is knitted by intertwining the back threads with the warp threads, and the back threads have good stitching, making it possible to provide a dense and elegant lace. However, the production of river lace by river lace machines is quite expensive and economically extremely disadvantageous, as the speed of the machinery is slow and requires the highest level of technology.

[Problems to be Solved by the Invention] Therefore, the present invention is directed to a lace fabric with a river lace style that has good stitching, is dense, and has a high class quality, and is particularly designed to be knitted using a Raschel machine that can be mass-produced in a single hour. The objective is to provide a lace fabric with raschel knitting.

[A Thousand Steps to Solve the Problem] In achieving the above-mentioned object, the present invention specifically uses a plurality of warp threads and at least two sets of back threads, a first set and a second set. The lace fabric is raschel knitted, and one of the back threads of the first set is arranged from the first warp at equal intervals in the longitudinal direction of the warp between the adjacent first and second warp threads. on the first cross-crossing path toward the second warp, and on the second

and the second warp from the first warp to the second warp, and are knitted into the adjacent first and second warps, and the second set Between the second warp and the third warp adjacent thereto, one of the back threads runs from the second warp to the third warp at equal intervals in the length direction of the warp. and a fourth crossway running from the third warp to the second warp, so that the adjacent second and third warps are knitted, and the second set of The other of the back threads is connected to the adjacent second and third
Between the warp threads, the warp threads are spaced at regular intervals in the length direction of the warp threads, on the third cross-crossing path from the third warp to the second warp, and from the second warp to the third warp. The fourth crossing path crosses the adjacent second
A lace fabric is formed by Raschel knitting, which is knitted on the third warp.

[Embodiments of the Present Invention] Hereinafter, the lace fabric by raschel knitting according to the present invention will be described in detail based on specific embodiments shown in the drawings.

In FIG. 1, the lace fabric by raschel knitting according to the present invention (1) has a plurality of warp threads (2) shown by dashed lines.
and at least two sets of back yarns, for example, as shown in FIG. 3) and a second set of back yarns <4> consisting of the back yarns (4A) shown by thick dotted lines and the back yarns (4B) shown by thick solid lines.The preferred example shown in FIG. According to the above warp (2
), 30 denier nylon thread is used, and one back thread (3A) of the first set and one back thread (3A) of the second set are used.
4A), a 50 denier single-twist nylon thread is used, and the other back thread of the first set (3B>) and the other back thread of the second set (4B) are 30 denier nylon threads. These yarns are not limited to the above-mentioned types of yarns.The above preferred examples are selected to balance the finish of each part organized by the warp and back yarns. Just an example.

To explain the structure of the lace fabric (1) according to the present invention in more detail, first, one (3A) of the first set of back threads (3) is connected to the adjacent first and second warp threads (2A> and (2A)). 2B), first cross paths (5) from the first warp (2A) to the second warp (2B) are spaced at equal intervals {L) in the length direction of the warp (2). upper, and the second warp (2

On the other hand, the other (3B) of the first set of weft yarns (3) is equally spaced in the length direction of the warp yarn (2) between the adjacent first and second warp yarns <2A> and (2B). Every interval (L),
On the first cross path (5) from the second warp (2B> to the first warp (2A), and from the first warp (2A> to the second warp (2B)) It is traversed on the second traversing path (6) towards which the warps are knitted against the adjacent first and second warps (2^), (2).
