Description

Single circular knitting machine and method for manufacturing a single fabric using the same}

The present invention relates to a knitting method of a single fabric and a single fabric manufactured by the same, and in more detail, using a non-covering yarn and a covering yarn such as a special yarn and a general yarn such as a slub yarn or a nepza, the uncovering yarn protrudes upwards. The covering yarn goes down and relates to a single circular knitting machine capable of producing a frying effect when viewed in cross section or in front and a single fabric knitting method using the single circular knitting machine.

Circular knitting machine is a general term for circular knitting machine. Knitting machines for knitting in a tubular shape are divided into a knitting machine (a cutting-only knitting machine for cutting), a molding knitting machine (a garment length or a sweater knitting machine), and a socks knitting machine. Also available are single needle or double needle, single cylinder type and double cylinder type (ribbed, double-sided, double headed).

In single needles, weaving, stripes, and plot jacquards are made. A double jacquard is made in the rib type of the double needle, various jersey structures are made in the double side type, and an uneven pattern is made in the double head type.

Typical types of fabrics vary depending on the weaving, thickness, and elasticity. Common types of fabrics are single, fried, and cotton.

The single can be seen in many underwear or t-shirts and is stretchy in the transverse direction. And the fry is similar to the single fabric, but the elasticity in the transverse direction is pulled to a very good fabric and is less elastic to return to its place when released.

The fries are the same fabric in the front and back, the most seen in autumn and winter children and baby products. Cotton wool is most often found in autumn and winter hooded t-shirts or zip-up jumpers.

On the other hand, the fabric is knitted in a frying method in a circular knitting machine is a form in which irregularities are repeatedly formed up and down the shape of the fabric.

General ling can be served in a fried method, but a special yarn such as slub yarn or Nepsa can not provide a fabric excellent in elasticity due to the nature of the organization does not knit in a fried method occurs.

Below the clearing position 61 of the first-stage cylinder cam is positioned the misposition 63 of the two-stage cylinder cam, and below the misposition 62 of the first-stage cylinder cam is the clearing position 64 of the two-stage cylinder cam. do.

In the clearing positions 61 and 64, the needle is threaded through the yarn that has been fed, but in the mispositions 62 and 63, the needle is passed without the needle.

Yarns applied to the present invention are two types, one of which is an uncovered yarn such as Neb yarn, Slub yarn or ordinary yarn, and the other is a covering yarn.

Neb yarn is a bundle of fibers or cotton balls of different color from the base yarn. Slub yarn is a part that is thicker and has little or no twist. It is.

The covering yarns are shorter in length but relatively smooth and less fluff than other yarns.

In the present invention, the two first needles are moved together along the first stage cylinder cam while paired together, and the second second needles are moved together along the second stage cylinder cam while paired together. The uncovering yarn is supplied to the clearing position 61 of the 1st stage cylinder cam, and the covering yarn is supplied to the misposition 62 of the 1st stage cylinder cam.

Therefore, the uncovered yarn is supplied at the misposition 63 from the two-stage cylinder cam, and the covering yarn is supplied from the clearing position 64.

Hereinafter, a knitting method using a single circular knitting machine according to an embodiment of the present invention.

First, two first needles are supplied with an uncovering yarn while passing through the clearing position 61 of the first-stage cylinder cam.

Then, the first two needles are hooked to form a ring and an elastic part is formed due to the nature of the uncovering yarn. When the first needles pass through the misposition 62, the covering yarn is supplied, but the first two needles are supplied. You pass by not wearing it.

When the second needle passes through the misposition 63, an uncovering yarn is supplied, but the second needle passes through the second needle without passing the second needle, and the second needle passes through the clearing position 64. At this time, the covering yarn is supplied and two second needles are formed to form a ring to form an inelastic portion which is characteristic of the covering yarn.

The cross-section of the present invention, the single fabric knitted as described above is shown in Figure 5, the uncovered yarn is formed by the convex portion 72 is formed a volume, the covering yarn is formed as a flat portion 71 to go down.

If necessary, the first needle may be changed to form three or more pairs, and the second needle may also be changed to form four or more pairs.

In addition, the number of pairs of the first needle and the number of pairs of the second needle may be configured to be different.

The fabric knitted by the present invention knitting method of a single fabric is a shape as shown in FIG.

In the present invention, the knitting method of the single fabric and the single fabric knitted thereby have a convex portion 72 formed on one side of the covering yarn relative to the fabric knitted by the conventional fried method, so that an excellent fit is produced.

And the shape of the front and back is different, the effect can be used as a reversible clothes that can be turned upside down.

In addition, when knitting in a frying method, the weight of 400g per yard is produced. According to the knitting method of the present invention, a single fabric is lightened to 250g per yard, resulting in a lighter weight and a reduction in manufacturing cost.
