Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the provision of a knitted fabric with double inner and outer layers that is excellent in heat retention, moisture absorption, etc.

BACKGROUND OF THE INVENTION Conventionally, knitted fabrics with inner and outer layers that have heat retention properties, moisture absorption properties, etc. are known. For example, the inner fabric that comes into direct contact with the body is a knitted fabric with through holes formed by tactile knitting, while the outer fabric that faces the outside world is a plain knitted fabric, with a double fabric structure that connects both the inner and outer fabrics. In this case, a space is defined by the tacked holes. However, with this type of structure, in the transparent hole part due to the tactile stitch, other adjacent loops are pulled by the tuck stitch loop, so the hole diameter becomes substantially smaller and a sufficient unevenness is obtained. For this reason, air retention in the space formed by the through holes in direct contact with the body is poor, and there is a major drawback in terms of heat retention.

The present invention relates to an improvement on the conventional double knitted knitted fabric of this kind, and its characteristics are that the outer knitted fabric is knitted into a plain knitted fabric, and the inner knitted fabric is knitted every two wales over the entire surface of the knitted fabric. Between each two wales, through holes are formed by locking the sinker loops of several courses at once to the sinker loops of the next course, and are arranged in rows at short intervals in the wale direction, and The knitted fabric is knitted into a perforated fabric in which the positions of the perforations are staggered in each case, and in each of the several courses of the outer knitted fabric, a connecting loop using a sinker loop is formed every several wales in the same course. , several courses of sinker loops in the perforated knitted fabric are knitted together with a needle loop following the sinker loop to which the two knitted fabrics are integrally dot stitched.

The present invention will be described in detail with reference to the embodiments shown below. Figures 1, 1, and 2 show the external appearance and cross-sectional view of the knitted fabric of the present invention, and A indicates the inner side according to the present invention. The fabric A is a knitted fabric, and as illustrated in Fig. 1, the fabric A has perforations as described below in the wale direction and course direction of the fabric at appropriate intervals over the entire surface of the fabric. The B shown in FIG. 1 is the outer knitted fabric according to the present invention, and the same fabric B
As will be described later, the inner and outer knitted fabrics A and B according to the present invention are formed from the outer knitted fabric B side as shown in the cross-sectional view of FIG. The connecting loop 5c is connected to the inner knitted fabric A.
By knitting it to the side, it is polymerized and integrated as a double knitted fabric, and at this time, the inner knitted fabric A is brought into contact with the body Y, and the outer knitted fabric B is used so as to face the outside world. By maintaining sufficient space between the inner knitted fabric A, which has an uneven shape due to the scattering of through holes A, and the bag-shaped portion B formed between the two fabrics A and B, it is possible to It is designed to provide great heat retention and moisture absorption properties that cannot be obtained with fabrics.Next, the knitting structures of both the inner and outer knitted fabrics A and B will be described in detail.

Figure 3 shows outer knitted fabric B, Figure 4 shows inner knitted fabric A.
Figure 5 shows both fabrics A and B that are integrated.
When knitting the knitted fabric of the present invention, for example, a rib knitting machine or the like is used, and the outer knitted fabric B is knitted by the upper needle side as the lining side, and the outer knitted fabric B is knitted by the lower needle side. As a result, the inner knitted fabric B is knitted as the outer fabric. As shown in Fig. 3, the outer knitted fabric B is a plain knitted fabric with a series of needle loops 5a and sinker loops 5b, and every few wales and courses in the plain knitted structure, the needle loops on the inner knitted fabric A side The connecting loop 5c may be formed of a single loop existing in a dotted manner as shown in the figure, but in some cases it may be formed of several loops. The connecting loop 5c may be formed in a continuous course or in several wells. As shown in Fig. 4, the inner knitted fabric A has two adjacent wales a and b, and although the example shows two courses, several courses of sinker loops 1a, 1b... ,
By locking the outer sinker loops 2a, 2a of the wales a, b in the next course, the needle loops 3a, 4a, 3b on both sides,
4b, 3c, 4c... and even sinker loop 2
By tightening b, 2c..., a through hole A is formed between wales a and b as shown in the figure. two wales c, d
It can also be formed in exactly the same way. Further, as shown in this figure, the previously shown connecting loop 5c on the outer knitted fabric B side is connected to the illustrated wale b, for example.
d, it is knitted integrally as a part of the needle loop on the knitted fabric A side.

Regarding the arrangement of the through holes A in the inner knitted fabric A, as shown in Figs.
- relatively short intervals, such as every 3 courses,
Also, the through holes in adjacent wale sets are staggered. In addition, when connecting the connecting loop 5c, as shown in the fourth figure, several courses of sinker loops are knitted as a needle loop following a sinker loop that is locked at once. As a result, a large number of through-holes are formed over the entire surface, and the ground knitting portions between the through-holes are pulled and taut to take on a string-like shape. As shown in FIG. The double knitted fabric of the present invention in which the front and back fabrics A and B are integrated through the connecting loop 5c is obtained. When making and wearing various types of wear including underwear using this knitted fabric, as shown in Figure 2, the inner knitted fabric A is used.
It is used so that it is in contact with the Y side of the body,
It can be widely applied to underwear, pajamas, sportswear, and other wear.

In the knitted fabric according to the present invention, the outer knitted fabric B is a plain knitted fabric to maintain insulation against the outside world and shapeability of the entire double knitted fabric,
In the inner knitted fabric A, the sinker loops were arranged in rows at short intervals by locking the sinker loops of several courses at once between every two wales on the entire surface of the fabric A, and locking them to the sinker loops of the next course. By forming each through-hole, a knitted fabric with an extremely large number of through-holes can be obtained in addition to their staggered arrangement.Moreover, due to the tension of the sinker loop in each through-hole, most of the parts of the knitted fabric other than the through-holes are covered with strings. The fabric surface is taut in a shape, the shape of the holes is clear and the diameter is large, and the capacity of the space created by the group of holes as a whole is also increased. This knitted fabric is used as the inner side, and the sinker loops 5c of every few wales are used as connecting loops in each course at the required intervals on the outer knitted fabric, and these are used as sinker loops to lock the sinker loops of several courses at once. Since it is knitted with needle loops that follow, the two fabrics are integrated by this point-like joint, and the flexible flexibility of both fabrics and the double fabric as a whole is not inhibited.
The total space in which the through hole A and the bag-shaped part B communicate is extremely large, providing a large insulation space and freedom of movement at the same time. It is absorbed and is not exposed to the outside surface, and the contact surface of the knitted fabric A that comes into contact with the skin is extremely small, reducing thermal conductivity and reducing body heat dissipation. It has a great advantage in that it eliminates the hard and heavy feeling that is characteristic of double-layered fabrics and provides a flexible and comfortable wearing feeling.Also, since the binding loop is knitted as a needle loop on the mating fabric side, it is more comfortable than just locking. It is also advantageous in that it ensures reliable and strong connection and does not cause movement or slippage. In this case, the inner knitted fabric A is made of hygroscopic fibers, for example, natural fibers such as cotton wool, or blended yarns of natural fibers and synthetic fibers, and the outer knitted fabric B, which is the front side, is made of a plain knitted fabric and the hygroscopic fibers are used. Alternatively, by using hydrophobic synthetic fibers, underwear, other clothing, sports clothing, etc. that are excellent in moisture absorption, heat retention, and abrasion resistance can be easily obtained.

In addition, the inner knitted fabric A side is made of synthetic fibers with high heat retention and moisture permeability, such as synthetic fiber processed yarn, and the outer knitted fabric B side is made of natural fibers, etc.
If a material with high moisture absorption is used, a material suitable for sportswear etc. can be obtained.If conductive fibers are knitted at the same time on the inner side of the knitted fabric A, antistatic wear can be obtained; By knitting synthetic fibers that generate static electricity, such as Teviron, into the knitted fabric A, healthy underwear that prevents stiff shoulders due to the use of static electricity can be easily obtained.

The knitted fabric according to the present invention is as described above, but its greatest feature is that the front side is an outer knitted fabric B made of a plain knitted fabric, and the back side is made up of several courses of sinker loops in two adjacent wells, which are used for the next course. A large through hole is formed by locking the sinker loop in the inner knitted fabric A, and the knitted surface is made into an uneven knitted surface. It maximizes the space structure between the fabrics, which significantly improves its heat retention, and unlike the conventional heat retention of two layers of thick fabric, it can qualitatively improve heat retention. Moreover, the flat knitting on the front side increases the robustness of the fabric, and the uneven perforated knitting fabric on the inside eliminates adhesion to the skin, providing a comfortable and light feeling of wear and freedom of bending and stretching movements. In addition, in the present invention, when joining the two knitted fabrics A and B, the joining loop 5c is knitted and connected as a needle loop of the fabric A, so that the two fabrics A and B are reliably connected and connected to each other. This is an excellent improvement for inner and outer double-layered knitted fabrics, since it eliminates misalignment and movement of the fabric, ensures the formation of the bag-shaped part B, and does not cause deformation.
