DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a knitted fabric having two functions of waterproof (water-repellent) and antistatic (antistatic) and a method of knitting the knitted fabric.

[0002]

2. Description of the Related Art It is well known that a chemical treatment such as a waterproofing treatment is applied to the surface of a woven fabric and an antistatic treatment is applied to a back surface of the woven fabric to add functions such as waterproofness and antistaticity to the woven fabric. Generally, a woven fabric is composed of a warp and a weft, and although there are some exceptions, both of them intersect at a right angle and thus have excellent shape retention. Therefore, processing such as waterproofing and antistatic is easy, and many functionalities can be effectively added. On the other hand, since the knitted fabric (knit) is formed by continuous yarn loops, it is generally more porous than the woven fabric, has a larger amount of expansion and contraction, and has poor shape retention. Further, the knitted fabric has many restrictions such as a knitting structure and a composition density (measure), and it is difficult to add a waterproof function and an anti-static function. For this reason, conventionally, waterproof processing or antistatic processing has been performed on the yarn, and knitting of these processed yarns has produced a knitted product having a single function such as waterproofness or antistatic property.

[0003]

An object of the present invention is to provide a knitted fabric having two functions of a waterproof function and an antistatic function, and a method of knitting the knitted material.

[0004]

According to the present invention, in order to achieve the above object, (1) the ratio of the waterproofing yarn to the waterproofing yarn of the knitting yarn comprising the waterproofing yarn and the antistatic yarn is 50 to 75%, and the knitting yarn is flat. Knitting or rubber knitting and plating knitting, and (2) the proportion of the waterproofing yarn of the knitting yarn composed of the waterproofing yarn and the antistatic processing yarn is in the range of 50 to 75%, The knitting yarn is flat knitted or rubber knitted by a flat knitting machine or a knitting machine using a full fashion knitting machine having a two-hole type yarn feeder or a yarn feeder having the same performance as this, and It is characterized by knitting.

According to the present invention, a knitted fabric is provided with two functions of a waterproof function and an antistatic function.
By using two types of yarns, a waterproofing yarn subjected to a waterproofing process and an antistatic finishing yarn subjected to an antistatic treatment, and plating and knitting (additional yarn knitting), one surface, for example, The knitting is such that the outer surface is covered with a waterproof yarn and the other surface, for example, the back line is covered with an antistatic yarn.

[0006] In order to knit a knitted fabric as described above, it is necessary to perform a knitting by plating. For this reason, the structure of the knitted fabric is limited to a flat knit and a rubber knit which can be plated.
Therefore, knitting machines are also limited to the above-mentioned knitting machines capable of flat knitting and rubber knitting. For example, flat knitting machines (flat knitting machines, circular knitting machines, household knitting machines), full-fashion knitting machines and the like are used. Can be

FIG. 1 is a view showing an example of a knitted fabric according to the present invention. FIG. 1 shows an example of a flat knitting, in which (a) shows a front face and (b) shows a back face. As described above, two types of yarns are used for the knitting yarn, namely, the waterproofing yarn 1 and the antistatic yarn 2, and the knitted fabric has the waterproofing yarn 1 as shown in FIG. And the back surface is covered with the antistatic processed yarn 2 as shown in FIG.

FIG. 2 is a view showing a two-hole type yarn feeder 3 used for knitting the knitted fabric. The yarn feeder 3 is mounted on a flat knitting machine, a full fashion knitting machine, etc. The waterproofing yarn 1 and the antistatic yarn 2 are supplied to a knitting machine. The yarn feeder is not limited to the illustrated one, but may be any as long as it has a similar function.

In knitting of a knitted fabric, it is important to use an appropriate yarn count for the gauge of the knitted fabric, or to select a gauge suitable for the yarn count of the knitted fabric, which affects the finished knitted product. The applicant selects a gauge suitable for the gauge within the range of 5 to 16 gauge used for actually making a product of the knitted fabric gauge, and furthermore, waterproofing the thread. The knitted fabric is knitted by using the above-described structure and knitting machine. The voltage was measured.

[0010]

[Table 1]

In Table 1, the yarn used is 70% acrylic,
30% wool blended yarn, actually used 3
Using a waterproof yarn and an antistatic yarn of No. 6 twin yarn (2/36) and No. 40 single yarn (1/40), a practical gauge 5,
7, 12, 14, and 16 show the results of measuring the waterproofness (water repellency) and the charged voltage of a knitted fabric knitted using the above-described structure and machine.

In Table 1, Example 1 shows a function of a knitted fabric knitted with a practical gauge 5 using a knitting yarn composed of three waterproofing yarns of No. 36 twin yarn and two antistatic processing yarns of No. 36 twin yarn. (Waterproofing degree, charged voltage) are shown. According to the measurement result, the waterproofed degree was 70 and the charged voltage was 2000 V or less.

In Example 2, the function of a knitted fabric knitted with a practical gauge 5 was measured by using a knitting yarn composed of three waterproofed yarns of No. 36 twin yarn and one antistatic processed yarn of No. 36 twin yarn. The results show that the waterproofness was 80 and the charged voltage was 2000 V or less.

In Example 3, the function of a knitted fabric knitted with a practical gauge 7 was measured using a knitting yarn composed of three waterproofed yarns of No. 36 twin yarn and two antistatic processed yarns of No. 36 twin yarn. The results were shown, and the degree of waterproofness was 75 and the charged voltage was 2000 V or less.

In Example 4, the function of a knitted fabric knitted with a practical gauge 7 was measured by using a knitting yarn composed of two waterproofed yarns of No. 36 twin yarn and one antistatic processed yarn of No. 36 twin yarn. The results are shown, and the waterproofness is 80 and the charged voltage is 2000 V or less.

In Example 5, the function of a knitted fabric knitted with a practical gauge 7 was measured by using a knitting yarn composed of three waterproofed yarns of No. 36 twin yarn and one antistatic processed yarn of No. 36 twin yarn. The results are shown, and the waterproofness is 90 and the charged voltage is 2000 V or less.

In Example 6, the function of a knitted fabric knitted with a practical gauge 7 was measured using a knitting yarn composed of two waterproofed yarns of No. 36 double yarn and one antistatic processed yarn of No. 40 single yarn. As a result, the waterproofness was 70 and the charged voltage was 2000 V or more.

In Example 7, the function of a knitted fabric knitted with the practical gauge 12 was measured using a waterproofing yarn of one 36th twin yarn and an antistatic processed yarn of the same number. 75, and the charging voltage was 2000 V or less.

In Example 8, the function of a knitted fabric knitted with a practical gauge 14 was measured using a waterproof yarn of one 36th double yarn and a knitting yarn of one antistatic yarn of 40th single yarn. As a result, the waterproofness was 80 and the charged voltage was 2000 V or less.

In Example 9, the function of a knitted fabric knitted with the practical gauge 14 was measured using a waterproofing yarn of one 40th single yarn and a knitting yarn of the same antistatic finishing yarn. 75, and the charging voltage was 2000 V or less.

In the tenth embodiment, a knitting yarn composed of a waterproofing yarn of one 40th single yarn and an antistatic yarn of the same number is used.
As a result of measuring the function of the knitted fabric with the practical gauge 16,
The degree of waterproofness was 75 and the charged voltage was 2000 V or less.

In order to indicate that a waterproof or antistatic treatment has been added to a knitted product, it is generally necessary in the industry that the criterion be that the degree of waterproofing be 70 or more and the charging voltage be 2000 V or less. All of the knitted fabrics shown in Examples 1 to 5 and 7 to 10 obtained the results satisfying the above reference values. That is, the ratio of the waterproof yarn to the knitting yarn composed of the waterproof yarn and the antistatic yarn is 50 to 7%.
The knitted fabric knitted with a practical gauge of 5 to 16 using the above-mentioned organization and knitting machine has a waterproofness of 70 or more,
It became clear that a function with a charged voltage of 2000 V or less was added. However, as is clear from Example 6, when the ratio of the knitting yarn occupied by the waterproofing yarn is set to 80%, the waterproofing degree becomes 70 and the charging voltage becomes 2,000 or more, so that the determination standard is not satisfied. Thus, if the practical gauge is made smaller, the stitch becomes coarser.
If knitting is performed, both the degree of waterproofness and the charged voltage do not satisfy the criteria. Also, in knitting with a large practical gauge (dense stitches), the knitting ratio is generally about 50% or 50%. It is not practical to use for large knitting. Judging comprehensively from the above, practically, it is preferable to knit with a practical gauge of 5 or more using a waterproof knitting yarn of 50 to 75%.

[0023]

As is clear from the above description, according to the present invention, it is possible to add two functions of waterproofness and antistatic property to a knitted product, and it is most suitable for outdoor sportswear such as golf and fishing. A knitted product can be obtained.
