Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raised fabric in which a raised yarn constitutes a part of a knitted fabric structure.

[0002]

2. Description of the Related Art Conventionally, napped fabrics made of knitted fabric such as velour, corduroy, suede, and fleece have been manufactured using polyester, nylon, rayon, cotton yarn, etc. It has maintained a stable market scale for textiles. Regarding these raised fabrics, JP-A-11-152662 and JP-A-10-1
No. 5,895,3 has been proposed. These are proposed mainly for items related to wrinkles caused by bending of the fabric, pilling at the raised portion, and appearance and durability.

Since these raised fabrics are excellent in heat retention,
Most of them are worn in winter when the humidity is low, and of course there is the problem of static electricity. However, the current situation is that no countermeasures against static electricity problems have been proposed. In particular, in the case of synthetic fibers, which have lower water absorption and hygroscopicity than natural fibers, static electricity is easily generated. Naturally, with respect to the napped fabric whose main constituent fibers are synthetic fibers, the fact is that no measures are taken at all, although measures have been taken.

Static electricity is generated in any substance, but when the generated voltage is high, clinging occurs in the case of clothes,
Not only does it feel uncomfortable when you wear it, such as "pimples" caused by the generated static electricity, but stains also tend to adhere. In addition, there is a possibility that a flammable substance may catch fire due to static electricity, and in the field of work clothes, the problem of static electricity is important in the current situation where synthetic fibers with an antistatic function are used. Can be said.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention has a friction charge voltage of 3.0 k.
A raised fabric for clothing having an antistatic function, which is characterized by being v or less.

That is, in a raised fabric using a knitted fabric such as velour, corduroy, suede, and fleece as a base fabric,
The mainstream is knitting such as circular knitting and warp knitting. A characteristic that the friction withstand voltage is 3.0 kv or less can be imparted by knitting these anti-static synthetic fibers and conductive synthetic fibers in these knitted fabrics.

Here, as the antistatic fiber, a fiber provided with an antistatic agent can be applied. Fibers with this antistatic agent are
Generally, the antistatic agent is applied to the fabric by post-processing, and the method of kneading at the time of spinning is common. As an antistatic agent,
Hydrophilic polymers can be used, generally polyalkylene glycol polymers. By using antistatic fiber, it absorbs moisture in the atmosphere and disperses electric charge by ionic conduction to suppress static electricity.

Similarly, as the conductive fibers, there are metal fibers, carbon fibers, and fibers in which a conductive component is contained, and the conductive fibers have higher conductivity than fibers other than the conductive fibers other than synthetic fibers. . Static electricity is discharged by corona discharge due to the high conductivity of the conductive fiber. As the conductive component to be added to the fiber, there are vapor-deposited metal component on the surface, and a substance having high conductivity such as carbon black kneaded into the fiber. The yarns of the fibers may be long fibers or short fibers, and in the case of short fibers, staple-shaped conductive fibers can be mixed and spun. If the specific resistance of the yarn is within the following range, it can be said that the yarn is an antistatic fiber or a conductive fiber.

Although the definition of antistatic fiber and conductive fiber is not clear, generally, the specific resistance of the fiber is 10 ⁷ Ω · cm.
The level below is called conductive fiber, and 10 ⁸ to 10 ¹² Ω · cm is called antistatic fiber. General synthetic fibers are 10 ¹⁴ -10 ¹⁶
Ω · cm.

Generally, in knitted fabrics, whether one-sided or double-sided,
After knitting, the surface of the knitted fabric can be subjected to a physical nap treatment with scratched fluff. In a fleece which has been popular recently, the sinker loop of the single-sided circular knit is made long and made into a pile, so that the knitted fabric becomes thicker, and as a result, a higher raised height than that obtained by the raising process after knitting can be obtained.
As described above, the method of lengthening the sinker loops and raising the hairs can be knitted regardless of whether they are circular knitting or warp knitting. in this case,
The conductive fiber knitted as a yarn can be used in both the pile portion and the ground yarn portion, but it is preferable to mix the conductive fibers on the ground yarn side instead of the pile portion.
When it is used for the ground yarn, when it is seen in the final product, it is actually hidden by the pile and becomes difficult to see from the front side. In particular, in the case of conductive fibers containing carbon black, even if dyed, it is black due to the effect of carbon black and the color is difficult to see,
When viewed directly from the front, it is inferior in aesthetics. Therefore, the amount of conductive fibers used is preferably 10% by weight or less. Further, in order to impart an antistatic function, it is preferable to use 2% by weight or more. Of course, even if it is used for the pile portion, the antistatic function can be sufficiently maintained, so that there is no problem in the antistatic function even when used in the pile.

When the antistatic fiber is knitted, the antistatic effect is lower than that of the conductive fiber, and therefore the knitting rate is preferably 20% by weight or more. In this case, unlike conductive fibers, because no metal or carbon black is used,
Even if dyed, there is little concern that the aesthetics will deteriorate.

The frictional electrification voltage for evaluating the amount of generated static electricity is measured by the method described in JIS L1094.

The method of incorporating the antistatic fiber and the conductive fiber also includes a laminate and the like.

EXAMPLES The present invention will be specifically described below based on examples.

Example 1 A 24-gauge single circular knitting machine was used for knitting, using a polyester multifilament yarn of 110 decitex, 24 filaments for the ground yarn, and a 30% spun yarn of 100% polyester for the pile portion. At this time, conductive fibers made of polyester monofilament containing 22 decitex carbon black were aligned on five ground yarns at intervals of one and knitted. The mixing ratio of the conductive fibers was 5% by weight. The frictional electrification voltage at this time was 1.6 kv. The results are shown in Table 1.

The frictional electrification voltage at this time was 3.3 kv. The results are shown in Table 1.
