Description

Nonslip Just-density textile}

The present invention relates to a non-slip proper density fabric, and more particularly to a non-slip suitable high density fabric setting according to the proper density theory per unit area according to the number of rounds.

As a conventional method of producing a proper density fabric, Japanese Patent Application Laid-Open No. 51-102172 discloses a method of shrinking a fabric. In this method, although the weight of the fabric can be increased, There is a difficult problem.

On the other hand, Japanese Laid-Open Patent Application No. 60-246852, which is an improved patent of Japanese Patent Application Laid-Open No. 51-102172, reduces the knitted fabric by performing a specific chemical treatment so that the specific gravity is 0.8 g / Density knitted fabric having an air volume of less than 35% at the time of calender processing is disclosed. However, this technique is also a suitable technique for increasing the density of the fabric, and it is difficult to ensure the surface friction because of the difficulty in securing the non-slip property .

Recently, there has been known a technique in which a woven fabric woven with synthetic fibers is applied to a non-slip solution separately prepared in order to secure the non-slip property of the fabric. However, since the surface friction force of the fabric varies according to the non-slip solution used, There is a problem that it is difficult to ensure non-slip property.

In addition, the method of using the non-slip liquid has a complicated processing method and a separate production process of weaving and non-slip ensuring that the productivity is lowered and the production cost of the product is increased.

Korean Patent Registration No. 10-0365188. Korean Patent Publication No. 10-1999-0049140.

The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to design an appropriate density per unit area by appropriately designing the number of warp yarns and weft yarn yarn number so as to increase the surface frictional force without separately treating the non- Density fabrics.

The non-slip density density fabric according to the number of yarn counts and the fabric of the present invention which solves the above problems is made of 1/1 plain weave or 2/2 twill, 3/2 twill weave using warp yarns with weft Polyester 50D / 72F and weft Polyester150D / 3 Twill, or 4/4 Twill, and the density per unit area satisfies (Formula 1) or (Formula 2), and the fabric density

(Equation 1) --- Density = a

Where a is a constant and R is the diameter of yarn.

K(Equation 2) --- Density =

Here, K is a constant.

At this time, it is preferable to use polyester yarn yarn of 50d / 72f and twist number of 800 Twist / Meter, and it is preferable to use polyester twist yarn of 150d / 144f, 500 twist / meter.

Describing the above equations (1) and (2) according to the present invention,

As shown in <Figure 1>, the density of fabric is the number of received yarn per unit, which is determined by the diameter of the yarn and is inversely proportional to the diameter.

<Figure 1>

The basic theory of fabric density is as described in <Figure 1> above. However, since the diameter of the yarn can not be measured, in the present invention, the thickness (diameter) of the yarn is derived using the number.

Since the number is expressed in length per unit weight, it should be distinguished from the diameter. Here, the diameter relationship of the yarn using the number will be described with reference to <Fig. 2>.

<Figure 2>

If the yarn is assumed to be cylindrical as shown in <Figure 2> above, the relationship between yarn diameter and yarn number

The count = length (m) / weight (g), this case can be defined as the weight of the volume ratio = ^{= (R / 2) 2 L} . Where R is the diameter of the yarn, L is the length of the yarn, and D is the specific gravity of the yarn.

At this time, if the weight-related expression is substituted into the expression,

Number = Length (m) / Weight (g)

Where R is the diameter of the yarn, and the specific gravity of the yarn is the circumferential rate

The density is proportional to the square root of the number.
