Abstract
Description
본 발명은 자동차 충돌시에 승객을 보호해주는 에어백을 제조하는데 사용되는 에어백용 포지 및 그 제조 방법에 관한 것이다.The present invention relates to airbags for use in manufacturing airbags for protecting passengers in the event of a car crash and a method of manufacturing the same.
일반적으로 에어백용 포지는 피복제를 코팅하는 도포형포지와 피복제를 코팅하지 않는 비도포형 포지로 대별되는 바, 본 발명은 비도포형 에어백용 포지 및 그 제조방법에 관한 것이다.In general, airbags are classified into coated pouches for coating a coating agent and non-coated pouches that do not coat the coating material. The present invention relates to a pouch for an uncoated airbag and a method of manufacturing the same.
종래의 비도포형 에어백용 포지의 제조방법중에서 미국특허 5093163, 일본특허 공개평 4-121251, 일본특허공개평 4-281062, 한국특허공개 92-16632, 미국특허 4921735등은 평직과 같은 대칭구조로 제직하는 것이고, 또 일본특허공개평 4-281062에서는 고수축사를 사용해서 열수축시킴으로서 고밀도직물을 얻는 방법인 바 상기 방법은 고수축사와 같은 특수한 사를 필요로 하는 결점이 있으며 그 이외의 방법들은 고밀도로 제작하기 위하여 탬플을 사용하거나 강력한 받침에 의존하는 방법이므로 직기에 무리가 가는 결점이 있을뿐만 아니라 절사, 변부늘어짐등 포지상에 결점을 발생시켰다.Among the manufacturing methods of the conventional non-coated airbag forge, US Patent 5093163, Japanese Patent Laid-Open Publication No. 4-121251, Japanese Patent Laid-Open Publication No. 4-281062, Korean Patent Publication No. 92-16632, US Patent 4921735 and the like have a symmetrical structure such as plain weave. In Japanese Patent Laid-Open No. 4-281062, a method of obtaining high density fabrics by heat shrinking using high shrink yarns is a disadvantage that requires special yarns such as high shrink yarns. As it is a method of using a temple or a strong base for manufacturing, it not only has a defect in the loom, but also causes defects on the forge such as cutting and swelling.
또 미국특허 5073418에서는 바스켓직 또는 능직을 사용하고 있으나, 바스켓 직은 평직이나 리브직에 비하여 경사와 위사간에 교차점이 적으므로 조직이 불안정하여서 시간이 지남에 따라 진동에 의하여 기밀성이 낮아지거나 포지에 장력이 걸리대 조직이 변형되는 결점이 있다.In addition, US Patent 5073418 uses a basket weave or a twill weave, but basket weaves have less intersection points between inclined and weft yarns than plain weave or rib weaves, resulting in unstable tissue, resulting in lower airtightness due to vibrations or tension on forge. There is a drawback that the tissue is deformed.
본 발명은 이와 같은 문제점을 해결한 것으로서 이하 상세히 설명하면 다음과 같다.The present invention solves such a problem as described below in detail.
자동차가 충돌하면 고온고압의 질소가스가 에어백을 팽창시키며 이때 약 50KPa 내외의 압력이 에어백내부로 전달되는 바, 이때 에어백이 팽창압력에 의하여 손상되지 않아야만 승객을 안전하게 보호할 수가 있다.When the car collides, the high-temperature, high-pressure nitrogen gas inflates the airbag. At this time, a pressure of about 50 KPa is transferred to the inside of the airbag. At this time, the airbag must not be damaged by the inflation pressure to protect the passengers.
본 발명의 에어백용 포지는 인장강도 400 파운드/ 인치 이상, 인열강도 66파운드 이상, 공기투과도 1.27cmH2O의 압력차에서 0.5cc/cm2초 이하, 내열성(FMVSSForges for airbags of the present invention have a tensile strength of 400 pounds / inch or more, tear strength of 66 pounds or more, air permeability of 1.27 cmH 2 O at a pressure difference of 0.5 cc / cm 2 seconds or less, and heat resistance (FMVSS
-302에 준한 방법)FMVSS :미국연방자동차안정기준) 4인치/분 이하의 물성을 가지며 경리브(wsrp rib)조직으로 된 것이다.Method according to -302) FMVSS: US Federal Motor Vehicle Safety Standard) It has a physical property of 4 inches / minute or less and is made of a hard rib (wsrp rib) structure.
본 발명에서 경리브직은 종광이 1회 운동할때 2회이상의 바듸침에 의하여 2본이상의 위사를 위입시키는 것이므로 평직 및 능직보다 고밀도의 직물을 얻을 수가 있다.In the present invention, since the light rib weave two or more weft yarns by changing two or more times when heald is a single movement, it is possible to obtain a fabric having a higher density than plain weave and twill weave.
또 경리브직은 경사 및 위사의 밀도조정이 평직, 능직 및 바스켓직에 비하여 용이하여 고밀도로 제직할 수 있을 뿐만 아니라 경, 위사방향에서 강도가 균일한 고강도의 포지를 얻을 수 있는 장점이 있다.In addition, the rigid rib weave can be densely adjusted because the density of warp and weft yarns is easier than that of plain weave, twill weave and basket weave, and has the advantage of obtaining high strength forge with uniform strength in the light and weft directions.
본 발명의 에어백용 포지는 열가소성합성섬유, 즉 나일론 66, 나일론 6, 나일론 46 또는 폴리에스테르 400~450데니어의 원사를 사용하여 경사 및 위사의 밀도가 각각 49~60본/인치, 53~66 본/인치가 되게 경리브직으로 제직한다.The airbag for air bag of the present invention using a thermoplastic synthetic fiber, that is, nylon 66, nylon 6, nylon 46 or polyester 400 ~ 450 denier yarns of 49-60 cases / inch, 53-66 cases of warp and weft yarn respectively Weave in a ribbed fabric so that it will be about an inch.
본 발명에서 경, 위사의 밀도가 이보다 낮으면 인장강도, 인열강도 및 공기 투과도가 본 발명의 기준에 미치지 못하여 에어백용 포지의 기능을 발휘할 수가 없다.In the present invention, when the density of light and weft yarn is lower than this, tensile strength, tear strength, and air permeability do not meet the criteria of the present invention, and thus cannot function as an airbag forge.
이와 같이 제직한 포지를 90~100℃의 온도에서 3~5분간 연속식정련을 행한후 100~150℃로 실린더건조하고 180~200℃로 열고정후 150~200℃의 온도와 50~150㎏f/㎠의 압력으로 카렌더링하여 기밀성을 증가시키며 보다 얇은 에어백용 포지를 제조한다.After weaving the woven fabric in this manner for 3 to 5 minutes at 90 ~ 100 ℃, dry the cylinder at 100 ~ 150 ℃ and heat it at 180 ~ 200 ℃, and fix it at 150 ~ 200 ℃ and 50 ~ 150㎏f. Calendering at a pressure of / cm 2 increases airtightness and produces thinner airbags.
본 발명에서 정련시간이 3분미만일 경우는 정련효과가 충분하지 않으며 5분을 초과하여도 그 이상의 정련효과를 나타내지 않는다.In the present invention, when the refining time is less than 3 minutes, the refining effect is not sufficient, and even when the refining time exceeds 5 minutes, no refining effect is exhibited.
180℃미만으로 열고정하면 형태안정성이 미흡하며 열고정온도가 200℃를 초과할 경우에는 황변현상과 함께 원사의 구조가 변화되어서 물성저하를 수반하게 된다.If the heat setting is lower than 180 ℃, the shape stability is insufficient. If the heat setting temperature is higher than 200 ℃, the yellowing phenomenon and the structure of the yarn are changed, resulting in deterioration of physical properties.
또한 카렌더링할때 온도가 150℃미만일 경우는 에어백으로서의 기밀성이 유지될수 있을 만큼 융착이 되지 못하며 200℃를 초과하면 포지의 강도가 400파운드/인치미만으로 낮아져 에어백용 포지로 사용할 수가 없다.In addition, when the temperature is less than 150 ℃ when the calendering is not fused enough to maintain the airtightness as an air bag, if it exceeds 200 ℃ the strength of the paper is lowered to less than 400 pounds / inch can not be used as air bags for air bags.
또 카렌더링할때 50㎏f/㎠미만의 압력에서는 융착효과가 없으며 150㎏f/㎠초과시에는 포지의 강도가 기준이하로 낮아짐을 확인할 수가 있었다.In addition, when the calendering was less than 50kgf / ㎠ pressure fusion effect and 150kgf / ㎠ exceeded the strength of the forge was confirmed to be lower than the standard.

단사섬도 6.2 데니어, 단사장력 7.89g/d, 절단신도 21%의 나일론 66, 420데니어/68필라멘트의 원사를 표 1과 같은 밀도의 경리브직으로 제직하며 95℃에서 3분간 정련, 120℃의 실린더 건조기에서 4분간 건조, 190℃에서 히트셋시킨후 180℃, 80㎏/㎠으로 카렌더링하여 표 1과 같은 결과를 얻었다.Weaving yarns of nylon 66 and 420 denier / 68 filament with single yarn fineness of 6.2 denier, single high tensile strength 7.89 g / d and 21% elongation are stiffened at 95 ° C for 3 minutes, and refined at 95 ℃ for 3 minutes. After drying for 4 minutes in a drier, heat-set at 190 ° C and then calendered at 180 ° C, 80 kg / ㎠ to obtain the results shown in Table 1.

[비교예 1]Comparative Example 1
실시예에 준한 원사로써 밀도 49×49 본/인치의 평직으로 제직한후 실시예에 준하여 정련, 건조 및 히트셋후 통상의 클로로프렌 고무조성물을 코팅하였다.After weaving into a plain weave having a density of 49 × 49 bone / inch as a yarn according to the examples, the conventional chloroprene rubber composition was coated after refining, drying, and heat set according to the examples.
[비교예 2]Comparative Example 2
실시예에 준한 원사로써 밀도 45×72 본/인치의 평직으로 제직한후 실시예와 같은 방법으로 정련, 건조, 히트셋, 카렌더링하였다.After weaving into a plain weave having a density of 45 × 72 bone / inch as a yarn according to the examples, it was refined, dried, heatset, and calendered in the same manner as in the examples.
[비교예 3]Comparative Example 3
실시예에 준한 원사로써 47×47 본/인치의 평직으로 제직한후 실시예와 같은 방법으로 정련, 건조, 히트셋, 카렌더링하였다.After weaving into a plain weave of 47 × 47 bones / inch as a yarn according to the examples, it was refined, dried, heatset, and calendered in the same manner as in the examples.
[비교예 4][Comparative Example 4]
실시예에 준한 원사로써 49×40 본/인치의 위리브직으로 제직한후 실시예와 같은 방법으로 정련, 건조, 히트셋, 카렌더링하였다.After weaving with 49 × 40 bone / inch weave ribs as the yarns according to the examples, it was refined, dried, heatset, and calendered in the same manner as in the examples.
[비교예 5][Comparative Example 5]
실시예에 준한 원사로써 50×50 본/인치의 평직으로 제직한후 실시예와 같은 방법으로 정련, 건조, 히트셋, 카렌더링하였다.After weaving into a plain weave of 50 × 50 bone / inch as a yarn according to the example, it was refined, dried, heatset, and calendered in the same manner as in the example.
[비교예 6]Comparative Example 6
단사섬도 5.9 데니어, 단사강력 8.63g/d, 절단신호 18.5%의 나일론 66 840데니어/140필라멘트를 밀도 24×24본/인치의 평직으로 제직한후 실시예와 같은 방법으로 정련, 건조, 히트셋, 카렌더링하였다.Single yarn fineness 5.9 denier, single yarn strength 8.63g / d, cutting signal 18.5% nylon 66 840 denier / 140 filament was woven into a plain weave of 24 × 24 patterns / inch of density, and then refined, dried, and heat set in the same manner as in Example. And calendered.
표 2에서 알 수 있는 바와 같이 비교예 1에서는 코팅에 의하여 인열강도가 같은 밀도인 비교예 3에 비하여 낮게 나타남을 알 수 있는 바, 이는 코팅가공이 인열강도에 역효과적임을 알 수 있다.As can be seen in Table 2, in Comparative Example 1, it can be seen that the tear strength is lower than that of Comparative Example 3 having the same density by coating, which indicates that the coating process is ineffective for tear strength.
비교예 2~4는 인장강도가 기준에 미치지 못하며, 특히 비교예 4는 위리브직이므로 제직시 경사장력과 위사방향의 수축에 의하여 오히려 평직에 비하여 위사밀도가 낮다.In Comparative Examples 2 to 4, the tensile strength does not meet the standard. In particular, Comparative Example 4 is a weave rib, so weft density is lower than that of the plain weave due to inclination tension and contraction in the weft direction during weaving.
비교예 5에서는 공기투과도가 기준에 미달됨을 알 수가 있고, 비교예 6의 840 데니어의 포지는 강도가 우수하나 기밀성이 낮을 뿐 아니라 포지의 형태안정성이 좋지 못하여 봉제시나 비도포형 에어백으로서 사용시에 제기능을 발휘할 수가 없다.In Comparative Example 5, it can be seen that the air permeability is lower than the standard. The 840 denier forge of Comparative Example 6 has excellent strength but low airtightness and poor form stability of the forge. It cannot function.
