Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a circular knitted fabric having piles used for clothes and materials with a double knit circular knitting machine.

[0002]

2. Description of the Related Art Conventionally, circular knitted fabrics having piles have been manufactured by a sinker pile knitting machine having a sinker in a single knit circular knitting machine having only cylinders, but the sinker pile knitting machine is a dedicated machine. Therefore, the organization is limited, and there is a limit in applications such as variety conversion. In addition, in a normal sinker pile knitting machine, the same course cannot be knitted by a plurality of feeders, and a sinker pile knitting machine capable of this is very inefficient in terms of yarn loss. In order to solve these problems, various ideas have been devised to knit a pile knitted fabric using a double knitting machine.

One example is a latch that uses a special device.
It is an opener method. This method makes it possible to knit a pile knitted fabric by using a device that opens the latch of the knitting needle that is closed, but the same course cannot be knitted by multiple feeders, which results in poor productivity, The pile height is also limited. As another example, a method of knitting a pile knitted fabric using water-soluble vinylon has been proposed,
Even if the gap between the cylinder and the dial is widened and the length of the yarn used is long, it is limited to low pile knitting without being directly connected to the pile height due to winding tension. It is also difficult, and the method of knitting the knitted fabric by combining it with the function of the double knit circular knitting machine has not been developed.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and uses a double-knit circular knitting machine to produce a pile knitted fabric having a high pile height and abundant surface changes. The purpose is to provide a manufacturing method.

[0005]

The present invention, which achieves the above-mentioned object, has the following constitution. That is, the present invention uses a double-knit circular knitting machine having a cylinder and a dial, supplies water-soluble vinylon to one of the cylinder or the dial to knit, and supplies a non-water-soluble fiber for forming a gland to the other. After knitting and knitting on the same fidder as the water-insoluble fibers for forming the ground, tuck or knit on the side where the water-soluble vinylon is knitted, and knitting on the ground side. A gist of the present invention is to provide a method for manufacturing a pile knitted fabric, which is characterized by dissolving a sex vinylon.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is described in detail below.
The water-soluble vinylon used in the present invention is a fiber produced from polyvinyl alcohol as a main raw material and easily dissolved in hot water at 60 to 70 ° C. As an example, Nichibi Co., Ltd. puts Solbron (trademark) on the market. .

In the present invention, the water-insoluble fiber is a fiber which does not dissolve under the condition in which the water-soluble vinylon dissolves. In the present invention, natural fibers such as cotton and wool, synthetic fibers such as polyester and nylon, rayon and the like. Regenerated fibers can be used.

The knitting machine used in the present invention can be applied to any model as long as it is a double knit circular knitting machine having a cylinder and a dial. A plain pile can be knitted with a plain machine, and a jacquard pile knitted fabric can be knitted with a jacquard knitting machine having a needle selection mechanism.

If the gauge of the knitting machine is low, a coarse knitted fabric can be knitted, and if the gauge of the knitting machine is high, a dense knitted fabric can be knitted.
The type of knitting machine may be selected according to the purpose of use.

Next, the basic knitting method of the present invention will be described with reference to FIG. In FIG. 1, the first feeder (F1)
Then, the water-soluble vinylon A is knitted by a dial, the non-water-soluble fiber B for forming the gland and the fiber C for pile forming are supplied to the second feeder, and the water-insoluble fiber for the gland forming B is knitted in a cylinder. The pile forming fibers C are knitted in a cylinder and tucked in a dial for knitting. In this case, the pile forming fibers C may be knitted with a dial or knitted. Further, the ground-forming non-water-soluble fiber B and the pile-forming fiber C may be the same fiber or different fibers.

In FIG. 2, one long hand and one short hand are alternately arranged on the cylinder and dial, respectively, and the first feeder (F
In 1), the water-soluble vinylon A is knitted with all the needles of the dial, and the second feeder (F2) is supplied with the gland-forming water-insoluble fiber B and the pile-forming fiber C to form the gland-forming water-insoluble water. Fiber B is knitted with the long needle of the cylinder,
The pile forming fiber C is knitted with the long needle of the cylinder and is tucked with the long needle of the dial to be knitted, and the water-insoluble fiber B for forming the ground is knitted with the short needle of the cylinder in the third feeder (F3) to form the pile forming fiber. C is knitted with the short needle of the cylinder and tucked with the short needle on the dial for knitting, and the course is completed by knitting the second feeder and the third feeder.

Further, in FIG. 3, one long hand and one short hand are alternately arranged on the cylinder, and two long and short hands are alternately arranged on the dial. In the first feeder (F1), water-soluble vinylon A is distributed over the entire dial. Knitted with needles, and the second feeder (F2) has a water-insoluble fiber B for forming a ground and a fiber C for forming a pile.
And knit the pile-forming fiber C with the long needle of the cylinder, and knit it with the long needle of the cylinder, and tack it with the long needle of the dial, and knit it with the third feeder (F3). ), The ground-forming water-insoluble fiber B is knitted with the short needle of the cylinder, the pile-forming fiber C is knitted with the short needle of the cylinder, and the dial is tacked with the short needle to knit, and the second feeder and the third feeder are knitted. So the course is completed.

When the knitted fabric thus knitted is treated with warm water to dissolve the water-soluble vinylon, the tack loop of the pile-forming fiber C to the dial is released from the knit loop of the water-soluble vinylon to form a pile. Due to this, the height of the pile increases depending on the size of the gap between the cylinder and the dial. In a normal knitting machine, this gap is about 5 mm, but it is possible to make it larger to make a high pile pile fabric.

In the knitting method in which the water-soluble vinylon is dissolved to form the pile, it is possible to knit the non-water-soluble ground forming fibers B and the pile forming fibers C in different feeders as shown in FIG. , Which has been implemented conventionally,
In this method, the pile forming fiber C is
When the pile is pulled into the knit structure of the water-insoluble fiber B for forming a gland, it is difficult to maintain the height of the pile, and only a low pile is formed. When the gland-forming water-insoluble fiber B and the pile-forming fiber C are supplied to the same feeder and knitted as in the present invention, the winding tension is applied to the knit structure of the gland-forming water-insoluble fiber B to form a pile. Since there is less influence on the working fibers C, it becomes possible to form a high pile according to the size of the gap between the cylinder and the dial.

Since the double knit circular knitting machine has a needle selection mechanism as in the above example, the needle knitting structure of the water-insoluble fiber completes the course with two or more feeders by utilizing this needle selection mechanism. By combining various types of organizations that combine two or more feeders to complete the course and one feeder to complete the course, and by using the jacquard needle selection mechanism,
Further, a pile knitted fabric with a rich surface change can be obtained by knitting the water-insoluble fibers with different types and brands.

Next, the finishing process including the dissolution of the water-soluble vinylon of the knitted fabric knitted as described above will be described. Since water-soluble vinylon is easily dissolved in warm water of 60 to 70 ° C., it is usually carried out at the same time as the refining step and sufficiently washed with water so that no dissolution residue remains. Since the loop pile is formed in this step, when maintaining the loop pile as a product, pay attention to the maintenance of the pile in the subsequent steps. When shirring the pile to process it into velor, be careful not to reduce the appearance of the product such as uncut pile. It is also possible to further raise the pile to make a fleece product.

[0017]

In the present invention, the water-soluble vinylon is supplied to one of the cylinder or the dial to knit it, and the non-water-soluble fiber for forming the ground and the non-water-soluble fiber for forming the pile are supplied and knitted in the same feeder. Therefore, the winding tension is applied to the knit structure of the water-insoluble fiber for forming the gland and the pile forming fiber is less affected. Therefore, when the water-soluble vinylon is removed in the finishing process, the size of the gap between the cylinder and the dial is increased. It becomes possible to form a high pile according to the above.

[0018]

The present invention will be described below in detail with reference to examples. The height of the pile in the examples was measured by taking a photograph of the cross section of the knitted fabric, and the pile density was visually counted in the number of 1 inch square.
