The present invention relates to a fabric fabric having an antistatic function, in particular, a knit fabric for comfortable antistatic having characteristics of breathability, sweat absorption and quick drying.

Various kinds of fibrous fabrics having antistatic function are widely used as various materials and uses in work sites for manufacturing, processing and processing precision parts such as integrated circuit process rooms and clean rooms where static electricity is concerned.

Among them, various configurations are proposed for antistatic clothing, antistatic hair, antistatic socks, etc., which are worn by workers, as antistatic functions to prevent damage caused by static electricity to components to be handled.

What is widely used has been manufactured to impart antistatic function by dispersing polyester filament, which is a synthetic fiber which does not generate its own dust, in a knitting machine and dispersing carbon conductive yarns, copper conductive yarns, and the like.

However, the above-mentioned conventional knitted knits for antistatic clothing have been considered for static electricity, but there are no considerations for the physical condition or health condition of the worker actually wearing and using.

In particular, in a closed room, such as a clean room, the room temperature is controlled so that there is no change in the room temperature. Workers feel pain due to excessive ventilation and non-hygroscopicity.

In addition, such non-absorbent, non-breathable, non-drying property, etc. in the process control, etc. requiring long hours of work has become a problem of serious health risks.

In the case of general fabrics, various materials and methods have been developed under the trade names "Coolmax", "Cullon", "Aerocool", etc., but such considerations are not made in fabrics having antistatic properties.

In order to solve this problem, attempts have been made to increase sweat absorption and quick-drying as an effect of capillary holes in an aggregate of polyester filaments having a heterocross section by weaving a mixture of conductive yarns using a polyester filament having a heterosection section. .

However, the polyester filament having such a sectional cross section does not have bulky yarn, so that a large area of the polyester filament is in contact with and sticks to the skin, resulting in a great decrease in comfort. there was.

In addition, since the carbon yarn is exposed to a continuous shape such as a parallel straight line of FIG. 1 or a square shape of FIG. It has been found that there are disadvantages such as causing optical illusion when worn for a long time, and workability is lowered.

Therefore, one major aspect of the knitted fabric for comfort antistatic of the present invention is that the conductive yarn is not exposed from the outside, so that the elegant design of the work clothes is possible, thereby providing fashion.

The present invention has been made in view of the above problems of the conventional power supply stage, and excellent in antistatic properties and free to choose the color can increase the workability, and economical and sufficient marketability in construction and manufacturing method An object of the present invention is to provide an antistatic coating fabric and a method of manufacturing the same.

Comfort fabric for knitted fabric according to the present invention for achieving the above object;

The antistatic knit fabric (F) is knitted as a double woven (double-sided) knit, and the double woven fabric comprises:

Polyester twisted yarns constituting the inner surface layer FI, which is the contact surface with the body, and the outer surface layer FO, which is the contact surface with the air, are provided in different thicknesses.

While the thickness of the polyester twisted yarn constituting the piece inner surface layer (FI) is selected to be thicker than the polyester twisted yarn constituting the piece outer surface FO,

By disposing the conductive yarn E of warp, weft and warp-weft mixed supply on the polyester twisted yarn which knits the piece inner surface layer FI, the conductive yarn E is concealed by the piece outer surface layer FO. Make up,

The conductive yarns E, which are equally spaced and mixed, of the piece inner surface layer FI are characterized by being continuous geometric bodies such as straight bodies and squares having an equal interval of about 4-10 mm.

The knitted fabric for comfort elimination of the present invention will be described in more detail together with the accompanying drawings.

Figure 4 is a longitudinal cross-sectional view of the fabric showing the configuration of, Figure 4 is a schematic explanatory diagram illustrating the effect of the comfortable antistatic knit fabric of the present invention, Figure 5 is an experiment of the absorption rate of water of the comfortable antistatic knit fabric of the present invention Result table, Figure 6 is a test result chart of the absorption rate compared to the moisture content rate.

The knitted fabric for comfortable antistatic of the present invention is characterized by providing an antistatic fabric having a multilayer structure.

The knitted fabric for comfort elimination of the present invention will be described in more detail with reference to the drawings.

Comfortable antistatic knit fabric (F) of the present invention is knitted and woven as a double woven (double-sided) knit,

The inner surface layer (FI) is knitted with sweat-absorbing fast-drying polyester twisted yarn (PI), and at the same interval of about 4-10 mm, the conductive yarns (E) such as carbon conductive yarn and copper conductive yarn are inclined, weft and inclined-weft. While inserting, knitting is carried out, and the knitting outer surface layer (FO) is knitted using only moisture-absorbing fast drying polyester twisted yarn (PO).

In the above description, it is used as a relative meaning of sweat-absorbing quick-drying, but in the present invention, it is preferable that the polyester twisted yarn of the hetero-monomer is preferable in selecting polyester twisted yarn.

Specifically, the polyester twisted yarn (PI) of the piece inner surface layer (FI) uses a relatively low filament polyester twisted yarn, for example, a yarn with a small number of filaments (coarse yarn) such as 75D / 36F,

Polyester twisted yarn (PO) of the outer surface layer (FO) is continuously knitted using a large number of yarns (thin yarns) having high filament number, such as 75D / 72F.

By adopting each of the polyester twisted yarn (PI) and polyester twisted yarn (PO) described above, and also having a heteromorphic cross section possible, it is possible to greatly increase the sweat absorptivity and quick-drying which are the objects of the present invention.

As such a structure, the inner surface layer FI having the conductive yarns E disposed at equal intervals together with the polyester twisted yarns PI is disposed in a shape coated with a thin polyester twisted yarn PO, so that the conductive yarns E Is not exposed to the outside at all.

Therefore, it is possible to apply aesthetics and a variety of designs, and even more desirable is that the conductive yarn (E) is finely coated with a thick polyester twisted yarn (PO), so that the short circuit of the conductive yarn (E) due to external impact or abrasion, etc. It is possible to prevent the deterioration of the antistatic function due to the above.

The cross-sectional structure of the comfortable static elimination knit fabric of the present invention having the above-described configuration is disclosed in FIG. 3 and will be described together with FIG. 4.

The inner surface layer (FI), which is the body side (B) of the worker along the center line (C), is knitted with a relatively thick polyester twisted yarn (PI) while the electrostatic carbon yarn is uniformly spaced. By inserting conductive yarns (E) such as copper conductive warriors,

The outer surface layer (FO) of the atmospheric side (A) is knitted by using only the sweat-absorbing fast drying polyester twisted yarn (PO) having a thin thickness,

The inter-fiber voids (Oi) between the polyester twisted yarns (PI) of the interlaminar inner surface layer (FI) are due to the difference in thickness than the inter-fiber voids (Oo) between the polyester twisted yarns (PO) of the outer-layer knit fabric (FI). It becomes big.

Therefore, as shown in the schematic diagram of FIG. 4, pores Oi and pores Oo having different cross-sectional areas are formed to form a capillary tube T, and pores Oi having a large cross-sectional area are separated from pores Oi having a small cross-sectional area. Inhaling capillary action is continuously induced.

  In addition to the capillary action, the sweat of the skin of the inner surface layer (FI) is absorbed by the sweat-absorbing fast-drying polyester twisted yarn (PI) on the inner surface and at the same time, the capillary outer layer (FO) has higher absorption capacity due to more capillaries per unit area. It is moved to polyester twisted yarn (PO) and dried in the surface air of the fabric to maintain comfort.

Due to this, sweat or moisture on the body side (B) is easily diverged to the atmosphere (A), so that sweat and quick drying are realized.

In addition, as described above, the conductive yarn E of the piece inner surface layer FI is concealed and the conductive yarn E is protected.

Examples of specific experiments according to the configuration of the present invention are as follows.

Quick Drying

Analysis of sweat absorption and quick drying conducted by Kolon Central Research Institute

-Absorbency measurement method: Wicking test is performed by the Bylek method according to KSK 0815. 5. 27.

-Sample Preparation: 2.5 × 20cm [Inclined × Weft] (3ea)

-Measurement: After dipping 2.5cm for 10 minutes in the weft direction, measure the length and average the value after measuring 3 times.

-Quick drying method; Moisten 50% of the dry sample weight in the sample and measure the quick dryness by weighing the sample at intervals of 10 minutes in a constant temperature and humidity room.

 The water content is calculated by calculating the amount of water remaining over time by converting the amount of water corresponding to 50% of the dry sample weight into 100.

Experimental Results: The average absorption rate is 13.3 cm / 10min, which shows that the absorption rate is considerably higher than that of 4-10 cm / 10min.

In particular, the moisture drying rate compared to the moisture content rate shows that the moisture drying speed increases rapidly at low moisture content, so that a comfortable drying rate is realized for sweating of 60% or less of the normal life sweating.

Surface resistance: 10E6Ω, Friction band voltage: 60V (In case of 200V or higher, internal circuits of fine structure ICs can be destroyed, and more than 500V can cause fatal damage to the IC.)
