Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a three-layer knitted fabric that is comfortable to wear and has a beautiful surface.

Conventionally, there has been a strong demand for two-layer or three-layer knitted fabrics with emphasis on wearing performance and functionality as knitted fabrics for sports clothing and cold weather clothing, and various knitted fabrics have been developed.
In order to improve comfort especially when sweating, a reversible knitted fabric with a two-layer structure in which the front side is made of hydrophobic fibers and the back side is made of hydrophilic fibers is generally used. The back side of this knitted fabric, which is in contact with the human body, is made of hydrophilic fibers, so it is very comfortable to wear under normal conditions, and when you sweat a little, the hydrophilic fibers absorb the sweat, so there is no discomfort. However, when sweating increases, the absorbed sweat comes into contact with the human body again, resulting in a so-called sticky feeling, which significantly worsens the feeling of wearing.

In addition, a three-layer knitted fabric is available in which the front and back sides of the reversible fabric are made of hydrophobic fibers in an attempt to eliminate the sticky feeling described above, but the water-absorbing effect is poor, especially the surface that comes into direct contact with the human body is made of hydrophobic fibers. As a result, the feeling of wearing under normal conditions was not pleasant.

The present inventors have arrived at the present invention as a result of various studies in order to compensate for such conventional drawbacks and create a three-layer knitted fabric that is comfortable to wear. When knitting a reversible fabric by knitting with dial needles and cylinder needles and performing tack binding with thin threads, one side of the reversible fabric is knitted with hydrophobic fibers and hydrophilic fibers thicker than the hydrophobic fibers. Moreover, the hydrophilic fibers are produced in a three-layer structure knitted fabric characterized by making the intermediate layer of the reversible knitted fabric using dial needles and cylinder needles take a welt state.

The present invention will be explained in more detail with reference to the drawings.

In FIG. 1, hydrophobic fibers a are knitted at yarn feeder 1 using dial short needles 10, and hydrophobic fibers a are knitted at yarn feeder 2 using dial long needles 20.

At the next yarn feeder 3, the cylinder needles 30 are selected so that the welt state is less than that of the next yarn feeder 4, and the hydrophobic fibers b are knitted. At the yarn feeder 5, which knits with a long welted state by selecting Jiya Guard needles, tuck binding is performed using a thin yarn d.

The hydrophilic fibers used in the method of the present invention include natural fibers such as cotton wool and hemp, as well as fibers that have been imparted with hydrophilicity, water absorbency, hygroscopicity, etc.

Furthermore, it is more effective if the hydrophilic fibers produced by the method of the present invention are as thick as possible than the hydrophobic fibers constituting the same side, but due to knitting problems, the denier difference is 2.
~3 times is good.

As shown in Fig. 2, the three-layer knitted fabric produced by the method of the present invention is reversible, and one side is composed of hydrophilic fibers 6 and hydrophobic fibers 7, and since the hydrophilic fibers 6 are made of thicker yarn, they can be directly applied to the human body. The area in contact with the fabric is naturally covered with hydrophilic fibers, making it comfortable to wear under normal conditions.

Also, when sweating, the sweat is absorbed by the hydrophilic fibers 6, and if the amount increases, it moves in the direction of the arrow, and after absorbing water, the outside air is released through the layer 8 on the front side, so it is very comfortable when sweating.

Furthermore, even when sweating is intense, the hydrophobic fibers 7 can prevent backflow to a large extent and so-called stickiness can be significantly eliminated, making it possible to provide a three-layer knitted fabric that is comfortable to wear under all conditions.

Furthermore, the three-layer knitted fabric produced by the method of the present invention does not require special machines or complicated processes, and can be produced in one step using a conventional knitting machine, making it very economical.

Example 1 Using a 24G double Ja Guard knitting machine, 150 denier polyester false twisted yarn was knitted as the hydrophobic fiber a shown in FIG. 1 using dial short needles and long needles at yarn feeders 1 and 2, respectively. Yarn feeder 3 and 4
Now, we will use a 100 denier polyester false-twisted yarn with a Jiyaguard pattern as shown in Figure 3 as a hydrophobic fabric.
It was knitted using 20/1 c.c. cotton thread as hydrophilic fabric and bound with 20 denier polyester filament. [In Fig. 3, the part marked with an x is cotton thread,
The unmarked portion is polyester false twisted yarn. ] After dyeing and finishing, I made the trepant and when I wore it, I found that it had the cool feel of cotton and was very comfortable to wear, and even when I sweated a lot due to exercise, I didn't feel any stickiness and it was comfortable.

Example 2 Using an 18G double Ja Guard knitting machine, 300 denier polyester false twisted yarn was knitted as the hydrophobic fiber a shown in FIG. 1 using dial short needles and long needles at yarn feeders 1 and 2, respectively. Yarn feeder 3 and 4
Now, the Jiyaguard pattern as shown in Figure 4 is made of hydrophobic fibers b.
150 denier polyester false twisted yarn,
The hydrophilic fiber c was knitted using 1/24M.C wool spun yarn and tack-bound with 30 denier polyester filament. [In Fig. 4, the x mark indicates wool spun yarn, and the unmarked line indicates polyester false twisted yarn. ] After wearing a prototype of the dyed sweatshirt, I found that it was very warm due to the wool on the inside, and was very comfortable with almost no sticky feeling even when I sweated while jogging.
