BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a warp-knitted fabric containing elastic yarns and a method for knitting the same.

0002

BACKGROUND OF THE INVENTION Hitherto, high stretch warp knitted fabrics containing elastic yarns are well known and have had considerable commercial success. Various knitted structures are known for imparting superior properties to knitted fabrics, thereby making them suitable for specific applications. For example, jersey knitted fabric, i.e., front lining (this may be abbreviated as FB in this specification) 2-
3, 1-0, rear recess (this may be abbreviated as BB in this specification) 1-0, 1-2 mesh structure has elasticity in two directions and high strength. Very suitable for the clothes you need (eg swimwear). However, jersey knits are not suitable for garments that require dominant stretchability in one direction and low strength, such as medical bandages, underwear (underwear), leisure wear, and outer wear.

[0003] A warp-knitted fabric in which the fiber direction stretches predominately in comparison to the other fiber directions is known from US Pat. No. 4,100,770. Although such knitted fabrics are suitable for some types of bandages and other knitted fabrics that require unidirectional stretch, they are heavy and have high strength, making them unsuitable for leisure or outer wear. U.S. Patent No. 3,552
, No. 154 describes another knitted fabric with unidirectional stretchability. However, this knitted fabric has the problem of "pull-out" of the elastic yarns (during wear, the elastic yarns break and protrude from the surface of the knitted fabric, deteriorating the appearance of the knitted fabric).

[0004] Delaware edition
ch) Structured warp knits have enjoyed considerable commercial success as outerwear and leisure wear due to their light weight, woven appearance and pleasant aesthetics. Such knitted fabrics are described in US Pat. No. 4,020,656. For reference, its full contents are included below, including the standard numbering for lap diagrams.

That is, FIG. 10 shows a set of typical conventional Delaware knitting patterns. In the figure, the position of the knitting needles for each of a number of successive courses is indicated by a row of horizontal dots. The top row shows the course immediately following the course shown by the row directly below it. As shown in this figure, this knitted fabric has an inelastic yarn 10 forming a raised knitting pattern as a whole, and a tufted knitting pattern (single needle o) that overlaps by one stitch.

rn). This figure shows four courses. Each stitch in the same course is formed identically to each other, and the knitting pattern is repeated alternately in every other course. Figure 1
Reference numeral 1 represents a knitting pattern formed by overlapping the front and rear recess patterns shown in FIG. 10 with each other. As seen in this figure, each stitch contains only two loops.

[0006] This knitted fabric consists only of inelastic yarns. Therefore, it has lower stretchability than knitted fabrics containing elastic yarns. An attempt to knit elastic yarn into the Delaware knitted fabric,
It hasn't been completely successful yet. In knitted fabrics made in this way, the displacement of the wale is large, that is, the position of the wale in the knitted fabric is unstable.In ordinary clothing, the wales are not parallel to each other and undulate from side to side. This is because there was a problem in that the appearance deteriorated as a result.

[0007]

[Problem to be solved by the invention] Therefore, this invention solves the following problems:
It is an object of the present invention to provide a warp knitted fabric which improves the above-mentioned Delaware knitting structure, has elastic threads woven into it, and does not have the above-mentioned drawbacks, and a method for manufacturing the same.

[0008]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a warp knitted fabric which contains elastic yarns, has dominant stretchability in the wale direction, and has wales whose positions are stable. The invention also includes an elastic thread,
To provide a warp knitted fabric which has predominant elasticity in the wale direction, has essentially no pull-out of elastic yarns during dressing, and is light in weight.

More specifically, the knitted fabric of the present invention has a predominant elasticity in the wale direction, and is preferably fed from the upper winding beam and the front reed, running between the wales of the knitted fabric, and extending between the wales. A large number of inelastic yarns forming a floating stitch are connected, preferably fed from a lower warp beam and a rear reed, and overlapped by a single stitch (chain stitch).
edleoverlap pillar stitch
It is a warp-knitted fabric consisting of a large number of elastic yarns forming the es). This knitted fabric has a different knitting pattern for each adjacent course, and has a knitting pattern that repeats every four courses at most. Each of these stitches consists of three overlapping loops, one of which consists of the elastic yarn and the other loop of the inelastic yarn.

[0010] In this invention, a knitted fabric having predominant elasticity in the wale direction is produced by using a warp knitting machine having a single row needle bed as follows (
It includes a method of warp knitting by steps including a), (b), and (c). (a) Inelastic yarn is supplied to the knitting machine from the upper warp winding beam and the front reed, (b) Elastic yarn is supplied to the knitting machine from the lower warp winding beam and the rear reed, and (c) the warp knitting machine is actuated to swing the front reed back and forth around the knitting needles in a different needle direction for each successive course and in the same needle direction according to a repeating pattern for up to every four courses; A floating stitch is formed that runs between the wales of the knitted material and connects these wales, and the rear reed is swung around the knitting needles of the warp knitting machine, thereby creating a tuft-like (chain-like) pattern that overlaps for one stitch. ) to form a knitting pattern.

[0011] Here, "knitted fabric having elasticity predominantly in the wale direction" refers to the degree of elasticity of the knitted fabric due to hand force along the wale direction, that is, the degree of elasticity of the knitted fabric along the wale direction (lengthwise direction of the knitted fabric). It means a knitted fabric in which the amount of elongation when a force is applied is at least twice the amount of elongation when a force is applied along the course direction of the knitted fabric. What is “elastic thread”?
Capable of being repeatedly stretched to a length of at least twice its original length as defined by ASTM Vol. 7.02 D-3106, and immediately and forcefully approximately It means a thread that returns to its original length. Typical commercially available elastic threads have an original length of 5
It can be stretched ~8 times. Spandex yarn is an elastic yarn and refers to a yarn made from fibers formed of long chain synthetic elastomers consisting of at least 85% linear polyurethane. Commercially available spandex yarns are manufactured by sequentially attaching a plurality of single fibers along their length to form a yarn.

"Non-elastic yarn" means a non-elastic knitting yarn that substantially retains its length when subjected to normal forces during processing and dressing. Typical examples are nylon and polyester fine threads and spun threads. Textured yarns, ie, yarns that, in their relaxed state, do not lie flat but take on a coiled or zigzag shape are also included in this definition of "inelastic yarn." The knitted fabric of this invention is manufactured using a knitting machine having a single needle bed. In the knitting patterns of the examples described later, a single row needle bed is used, and this needle bed includes a large number of warp winding beams and
Yarn is supplied from the front or first reed, and also from the second, third or rear reed.

[0013] This new knitted fabric, according to the invention, has 1
Preferably, it is produced on a tricot, Raschel or similar knitting machine using a row needle bed and at least two reeds, each known as a front reed and a rear reed. Yarn is fed to the knitting machine from an upper warp-wound beam and a lower warp-wound beam. Intermediate warp beams and intermediate reeds may also be used. The needle bed is equipped with knitting needles. The number of knitting needles may vary depending on the specifications of the knitting machine. Each reed has a number of thread retards that corresponds to the number of needles on the needle bed. These reeds can be swung a distance of one stitch or more in the warp direction opposite to the needle bed while adjusting the pattern. The reed can also be swung in the weft direction of the needle bed in order to swing the thread retard between the needles. By combining these rocking movements, the thread is fed to the needles, so that it is possible to knit.

The knitted fabric of the present invention is typical of Delaware knitted fabric in that the yarns of the rear heel are knitted in tufts. Further, each stitch in the course is formed identically. This new knitted fabric has a knitting pattern that repeats according to a repeating pattern of at most every four courses, although it differs between adjacent courses. This means that the knitting pattern repeats immediately after each second, third or fourth course, depending on the type of knitting desired. Each stitch of this new knit contains both elastic and inelastic yarns. Furthermore, each stitch includes three overlapping loops, one of which is made of the elastic yarn and the other loop is made of the inelastic yarn.

The present invention can be modified and changed in many ways with reference to the contents explained above and below. For example, in addition to the knitting pattern diagrams exemplified in this specification, many knitting patterns found in conventional knitted fabrics are possible with reference to the contents of this invention.

[0016]

[Operation] Inelastic yarn is supplied from the upper warp winding beam and the front reinforcement, and this inelastic yarn runs between the wales of the knitted fabric and forms floating knits that connect these wales, and the lower warp winding beam and the rear reinforcement. By supplying elastic yarn from the wafer, using the elastic yarn to form tassel stitches that overlap for one stitch, creating a different knitting pattern between each adjacent course, and repeating the same knitting pattern every four courses at most. , if each stitch is knitted with a triple loop consisting of one loop made of elastic yarn and two loops made of inelastic yarn, one of the triple loops of each stitch will be Since it is made of elastic yarn that forms tassels, it is possible to expand and contract predominantly in the wale direction. In addition, the other two loops are made of inelastic yarn, and this inelastic yarn runs between the wales and forms a floating knit that ties the wales together, thereby firmly fixing the wales. The displacement of the elastic thread is suppressed, and the protrusion (pull-out) of the elastic thread onto the surface of the garment is essentially eliminated. It is also lighter in weight.

[0017]

[Examples] Specific examples and comparative examples of the present invention will be described below. FIG. 1 shows a set of knitting patterns of a first embodiment of the knitted fabric of the present invention. In the figure, the position of the knitting needles for each of a number of successive courses is indicated by a row of horizontal dots. In this figure, elastic threads are designated by the number 13 and inelastic threads by the number 12. The stitches in the same course are formed identically to each other, and the knitting pattern is repeated alternately in every other course. The overlapping knitting pattern of two stitches with inelastic yarn 12 from the front reed running first in one course direction and then in the opposite direction in the next course is clearly shown. Furthermore, a tuft-like knitting pattern made of elastic thread 13 that overlaps by one stitch is clearly shown on the rear reed. This knitting pattern is FB0-2, 3-1; BB1-
0,0-1. FIG. 2 shows a knitting pattern in which the front recess and rear recess patterns of FIG. 1 are knitted one over the other. As can be seen in this figure, each stitch includes three loops, one of which is made of elastic yarn. This state is clearly shown in FIG. 2 at the needle bed position indicated by a thick line circle. That is, in the center of this circle, three ends of thread are shown being fed to one needle. The ends of these yarns are all knitted to form one stitch containing three overlapping loops. One of the three loops consists of an elastic yarn 13 forming a tuft-like stitch, and the other two loops consist of an inelastic yarn 12. Further, in FIG. 2, the wale direction running vertically and the course direction running horizontally are each shown by arrows. These directions apply to all of the knitting pattern figures described below.

FIG. 3 shows an example of a warp knitting machine having two reeds suitable for producing the knitted fabric of the present invention. The inelastic yarn 12 is fed from the upper warp-wound beam 20 to the front or first reed 24 . The yarn 12 is fed in a conventional manner through a stationary reed 22 which serves to keep the yarn separated. Each thread is passed from the reed through the thread guide to the reed 2.
4 and onto the needle bed 26. The elastic thread 13 is
It is supplied from the lower warp winding beam 21 to the needle bed 26 via the fixed reed 23 and the rear reed 25.

When using a warp knitting machine with two reeds as shown in FIG. 3, the inelastic yarn is fed from the upper warp winding beam through the first reed. When the knitting machine is started and the first reed is swung around the needles in the form of a two-needle overlapping pattern, when knitting inelastic yarns, each yarn wraps around two adjacent needles. to form a double loop. As a result, each inelastic yarn becomes two stitch components in adjacent wales in the course. In this way, per stitch (of inelastic yarn)
Two loops are formed. As soon as this two stitch overlap floating stitch is completed during the forming course, the yarn
Go to the next course. In this next course, the yarn is either knitted by the same needle in opposite directions (e.g. 0-2, 2-0), overlapping by two stitches, or floats towards the adjacent needle and then in the opposite direction. It is knitted with two stitches of overlap (
For example, 0-2, 3-1, see Figure 1), or two needles are knitted one on top of the other in the opposite direction by floating toward the two adjacent needles (
For example, 0-2, 4-2), or they may float toward three adjacent needles and overlap by two needles in the opposite direction (for example, 0-2, 5-3). In each example, the inelastic yarn connects adjacent wales of the knitted fabric by the weft, and in some embodiments, the inelastic yarn connects adjacent wales of the knitted fabric, and in some embodiments, connects the stitches of the current course or adjacent courses or both courses.
Tie with diagonal thread (float). The illustration shows open stitches, but to make one of these new knits,
Closed eyes may also be used. The pattern mentioned above, i.e., a two-needle overlap followed by a float on the next course, is called ``2-needle overlap''.
It is called "overlap" pattern. Typical knitting patterns for the front reel are 0-2, 2-0; 0-2, 3-
1; 0-2, 4-2; 0-2, 5-3; 2-0, 2-0
; 2-0, 1-3; 2-0, 2-4; 2-0, 3-5.

Elastic yarn is fed to the knitting machine from the lower warp beam and the rear reed. The knitting machine is operated, and the rear reed is swung around the needles while adjusting the pattern so that a tuft-like (chain-like) knitting pattern that overlaps by one stitch is formed. The stitches of this tassel stitch may be open or closed. The elastic yarn contained in the knitted fabric of this invention does not bind the wales of the knitted fabric. The knitting pattern of the rear reel is 1-0, 0-1; 0-1,
1-0; 1-0, 1-0; 1-0, 0-0, 0-1, 1

The inelastic yarn 12a is fed from the upper warp-wound beam 20a to the front or first reed 24a. The yarn 12a is fed in the usual manner through a fixed reed 22a which serves to keep the yarn separated. Each thread is threaded from the reed through a thread guide into the reed 24a and onto the needle bed 26a. The yarn 14a is supplied from the warp winding beam 27 to the needle bed 26a via a fixed reed 28 and an intermediate reed 29. The elastic yarn 13a is passed from the lower warp winding beam 21a to the needle bed 26a via the fixed reed 23a and the rear reed 25a.

The top row 25b represents the thread path of the rear reed. The middle row 29a represents the thread path of the intermediate reed. The bottom row 24b represents the thread path of the front reed. Particularly useful thread patterns when using the device shown in Figure 7 are:
In FIG. 8, which represents the thread path through which the thread is passed, a diagonal line drawn through a specific circle (thread path) is shown. As shown in the figure, only some thread paths in the middle and rear reeds have yarn passing through them, and all other thread paths in these reeds are empty. The thread paths through which the threads have passed are shifted every other row between rows 25b and 29a.

FIG. 9 represents a knitting pattern that can be used to produce one of the knitted fabrics of this invention. For clarity, only two ends of the elastic yarn 30 from the middle reed and the elastic yarn 13b from the rear reed and one end of the inelastic yarn 12b are shown in this figure.
