The present invention is to provide a double fabric having air component properties that can simplify the manufacturing process and lower the manufacturing cost at the time of manufacturing a shock-absorbing final product, such as air bags. In another aspect, the present invention is to provide a double fabric having air component properties that can hardly suppress the air leakage phenomenon when the layer separation portion is expanded by the air harden the fastening portion.
이와 같은 과제를 달성하기 위하여 본 발명의 공기부품성을 갖는 이중직물은, 서로 분리된 2개의 직물층으로 이루어진 층분리부분(A)과 서로 분리된 2개의 직물층들을 접결하는 접결부분(B)을 포함하여 공기부품성을 갖는 이중직물에 있어서, 상기 층분리부분(A)의 조직이 분리된 2개의 평직층을 형성하는 이중직이고, 상기 접결부분(B)의 조직이 경사 또는 위사 방향으로 4올 이상의 폭을 가지는 경리브직 및/또는 위리브직인 것을 특징으로 한다.In order to achieve the above object, the double fabric having the air component of the present invention, the layer separating portion (A) consisting of two fabric layers separated from each other and the connecting portion (B) for joining the two fabric layers separated from each other In the double fabric having an air component, including, the structure of the layer separating portion (A) is a double woven forming two separate plain weave layer, the texture of the connecting portion (B) is inclined or weft direction 4 It is characterized in that it is a light rib and / or a rib rib having a width of more than one.
이하, 본 발명을 첨부된 도면 등을 통하여 상세하게 설명한다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
먼저, 본 발명의 이중직물은 공기주입시 팽창될 수 있도록 서로 분리된 2개의 직물층으로 이루어진 층분리부분(A)과 서로 분리된 상기 2개의 직물층들을 접결시켜주는 접결부분(B)을 포함한다.First, the double fabric of the present invention includes a layer separating portion (A) consisting of two fabric layers separated from each other so as to expand upon air injection, and a connecting portion (B) for joining the two fabric layers separated from each other. do.
또한 패턴의 배치에 따라서는 층분리부분(A), 접결부분(B) 및 접결조직에 의해 폐쇄된 공간 밖의 영역(도 4의 2)으로 구성될 수도 있다. 본 발명의 층분리부분(A)의 조직은 도 1과 같이 분리된 2개의 평직층(도 5의 16,22)을 형성하는 이중직 이다.In addition, depending on the arrangement of the pattern may be composed of the layer separation portion (A), the connection portion (B) and the area outside the space closed by the connection structure (2 in FIG. 4). The structure of the layer separation portion (A) of the present invention is a double weave forming two plain weave layers (16, 22 of FIG. 5) separated as shown in FIG.
한편, 본 발명의 접결부분(B)은 도 3의 (a) 내지 (c)와 같은 경리브직으로 구성된 부분과, 도 3의 (d) 내지 (e)와 같은 위리브직으로 구성된 부분과, 상기 경리브직과 위리브직이 함께 사용된 부분으로 이루어 진다.On the other hand, the connection portion (B) of the present invention is a portion composed of a rigid rib fabric such as (a) to (c) of Figure 3, and a portion composed of a weave rib such as (d) to (e) of Figure 3, The hard rib weave and the weave rib consists of a portion used together.
본 발명의 접결부분(B)을 구성하는 상기 경리브직 및 위리브직은 접결효과를 위해 경사 또는 위사 방향으로 4올 이상의 폭을 갖도록 한다.The rib ribs and weave ribs constituting the engaging portion (B) of the present invention is to have a width of four or more in the inclined or weft direction for the binding effect.
경리브직으로는 도 3의 (a) 내지 (c)와 같은 2/2, 3/3 또는 4/4 조직을 사용할 수 있고, 위리브직으로는 도 3의 (d) 내지 (e)와 같은 2/2, 3/3 또는 4/4 조직을 사용할 수 있다.As the rib ribs, 2/2, 3/3 or 4/4 tissues such as (a) to (c) of FIG. 3 may be used, and as the weave ribs, such as (d) to (e) of FIG. 2/2, 3/3 or 4/4 tissue can be used.
경리브직을 경사방향으로 길게 선상으로 배치하거나, 위리브직을 위사방향으로 길게 선상으로 배치하는 경우에는 2/2, 3/3 및 4/4 조직을 병용하여 사용할 수도 있다.In the case of arranging the light rib in a long line in the oblique direction, or when arranging the weave rib in a long line in the weft direction, 2/2, 3/3, and 4/4 tissues may be used in combination.
이와 같이 본 발명은 접결부분의 조직으로 경리브직과 위리브직을 적절하게 배열하므로서 접결부의 강도를 높여 공기유출을 최대한 억제하고 제직성도 향상시 킴을 특징으로 한다. As described above, the present invention is characterized by improving the strength of the joining portion by maximally arranging the hard rib weave and the weave rib as the structure of the joining portion to suppress air leakage and improve the weaving property.
본 발명에서 접결부분이라 함은 층분리부분(A)의 분리된 두개의 직물층 (22,16)에 있어서, 상단층의 경사(9)가 하단층의 위사(11,12)와 조직점을 형성하거나, 상단층의 위사(23,24)가 하단층의 경사(10)와 조직점을 형성하여 두개의 직물층이 하나의 층을 형성하도록 만들어진 조직점, 조직선 또는 조직면을 의미한다.In the present invention, the joining portion refers to two
또한 조직점이란 경사와 위사가 위아래로 서로 교차되어 직물을 구성하는 부위를 의미한다.In addition, the tissue point refers to the area where the warp and weft cross each other up and down to form a fabric.
본 발명에서는, 경사방향으로 접결선을 형성하는 접결부분의 조직은 경리브직으로, 위사방향으로 접결선을 형성하는 접결부분의 조직은 위리브직으로 사용한다. 한편, 접결선이 곡선상으로 형성되는 접결부분(도 4의 3)의 조직으로는 경리브직을 주조직으로 위리브직을 보조조직으로 사용한다.In the present invention, the structure of the connection portion forming the connection line in the oblique direction is used as the rigid rib, and the structure of the connection portion forming the connection line in the weft direction is used as the weave rib. On the other hand, as a structure of the connection portion (3 in Fig. 4) where the connection line is formed in a curved shape, the rigid rib is used as the main structure and the weave rib is used as the auxiliary structure.
본 발명에서는 이중직물의 패턴을 구성할 때 접결부분의 조직으로 경사방향의 패턴은 경리브직을 넣고 위사방향의 패턴에는 위리브직을 넣어서 접결부 조직을 단단하게 하는 것을 특징으로 한다.In the present invention, when forming the pattern of the double fabric, the texture of the connection portion in the direction of the inclined direction put the rib ribs and weave in the pattern of the weft direction is characterized in that the texture of the connection portion is firm.
다시말해, 본 발명에서는 경사방향으로 접결부분이 길게 선상으로 형성되는 경우에는 접결부분의 조직으로 경리브직을 주조직으로 하며, 경리브직을 과다하게 넣을 때에는 당김현상을 최소화하기 위하여 위리브직을 보조조직으로 병용 사용한다.In other words, in the present invention, when the fastening portion is formed in a linear shape in the oblique direction, the hard rib weave is used as the main structure of the fastening portion, and when the excessively hard rib weave is provided, the auxiliary rib is supported to minimize the pulling phenomenon. Use in combination with tissue.
구체적으로 도 4의 7과 같이 경리브직의 폭이 8올 이상인 경우에는 위리브직을 병용 사용한다. 이때 위리브직을 병용 사용하지 않으면 제직시에 접결부 위사 의 굴곡이 심하게 되고 위사에 과다한 당김 현상인 발생하여 위사 절단이 심해져 제직성이 크게 저하될 수 있다.Specifically, as shown in FIG. 4, when the width of the rib rib is 8 or more, we use the rib rib together. At this time, if the weave ribs are not used in combination, the bending of the weft of the weaving part becomes severe during weaving, and an excessive pulling phenomenon occurs in the weft yarn, so that the weft cutting is severe and the weaving property may be greatly reduced.
경리브직이 경사방향으로 8올 이상의 폭을 가질 경우에는 도 4의 7과 같이 위리브직을 함께 사용하여 접결부분을 형성하는 것이 바람직 하다. 위리브직을 병용하지 않고 폭 방향으로 경리브직을 과다하게 배열하는 경우에는 제직시 접결부 위사의 굴곡이 심하게 되고 위사에 과다한 당김현상이 발생하여 위사의 절단으로 인해 제직성이 크게 저하될 수 있다.When the rib rib has a width of 8 or more in the inclined direction, it is preferable to form a joining portion by using the weave rib as shown in FIG. 4. When weaving the ribs excessively in the width direction without using the weave ribs together, the weft of the weft of the connection part becomes severe when weaving, and excessive pulling phenomenon occurs in the weft yarns. .
또한 위리브직이 위사방향으로 8올 이상의 폭을 가질 경우에는 도 4의 6과 같이 경리브직을 함게 사용하여 접결부분을 형성하는 것이 바람직 하다. 경리브직을 병용하지 않고 길이방향으로 위리브직을 과다하게 배열하는 경우에는 제직시 경사에 과다한 당김현상이 발생하여 경사의 절단으로 인해 제직성이 크게 저하될 수 있다.In addition, when the weave ribs have a width of 8 or more in the weft direction, it is preferable to form a joining portion by using the light rib ribs as shown in 6 of FIG. In the case of arranging excessively the weave ribs in the longitudinal direction without using the rib ribs, excessive pulling phenomenon may occur in the warp yarns during weaving and weaving may be greatly reduced due to the cutting of the warp yarns.
본 발명의 이중직물에는 공기통기성을 낮추기 위해 실리콘 고무가 코팅될 수도 있다.The double fabric of the present invention may be coated with silicone rubber to lower air breathability.

In addition, the double fabric of the present invention is not required to sew to simplify the manufacturing process of the final product can be made cheap manufacturing costs.
본 발명에 있어서, 접결부위의 단위길이당 공기배출량(ℓ/분·cm)은 공기압력을 조절하는 레규레이터, 유량계 및 압력계가 부착된 측정장치로 측정한다. 구 체적으로 2.5KPa 압력의 공기를 재단된 이중직물의 층분리부분으로 주입시켜 재단된 이중직물이 완전히 부풀려지게 한 다음, 단위시간(1분) 당 재단된 이중직물을 빠져나가는 전체 공기량을 ℓ단위로 측정한 후, 이를 재단된 이중직물의 전체 접결길이(cm)로 나누어 접결부위의 단위길이당 공기배출량을 구한다.In the present invention, the air discharge amount (l / min · cm) per unit length of the connection part is measured by a measuring device equipped with a regulator, a flow meter, and a pressure gauge for adjusting the air pressure. Specifically, the air of 2.5KPa pressure is injected into the layered part of the cut double fabric to completely inflate the cut double fabric, and then the total amount of air exiting the cut double fabric per unit time (1 minute) After the measurement, divide this by the total stitching length (cm) of the cut double fabric to find the amount of air discharged per unit length of the joint.
