Description
제1도는 본 고안의 평면도.1 is a plan view of the present invention.
제2도는 제1도의 A-A선 절단 단면도.2 is a cross-sectional view taken along the line A-A of FIG.
제3도는 본 고안의 경·위사 교차부분 확대도3 is an enlarged view of the cross section of the weft and weft of the present invention.
본 고안은 방적사 또는 필라먼트사나 스프릿트사를 사용하여 직선상으로 평행된 경사군과 평행된 2조의 위사군을 경사군의 상하에서 서로 반대방향으로 교차시켜서 된 망목상(網目狀) 부직포에 관한 것이다.The present invention relates to a mesh nonwoven fabric made by using a yarn or a filament yarn or a split yarn to cross a parallel group of warp yarns in a straight line and two sets of weft groups parallel to each other in the opposite direction from above and below the warp yarn. .
종래의 부직포는 스테플 화이바를 웨브(web) 상태로 하여 섬유 상호간을 접착제로 접착하여서 제조하거나 실을 경위사가 직교되게 접착하여서 된 것 또는 다수의 세섬유에 의하여 상호 연결된 망상(緖狀)의 연속 평행한 모노필라먼트의 대상(帶狀)의 층 2개를 서로 20°내지 90°의 각도로 중첩시켜 교차점을 열접착하거나(예:일본 공개실용신안공보증 공개번호 소 54-139783) 접착제로 접착 결합하여서 된 부직포 등이 있었으나 스테플화이바로 제조된 부직포는 경·위 방향의 강력이 약할뿐 아니라 접착제로서 섬유 상호간을 결합시켰기 때문에 습윤강도가 약한 결점이 있고, 경·위사가 직교되게 접착하여서 된 부직포는 경·의사 방향으로 칫수 안정성은 있으나, 신축성이 전혀 없어 인장이나 충격에 대하여 경·위사의 교차점이탈리되기 쉬운 결함이 있으며 대상(帶狀)의 모노필라멘트층 2개를 서로 20° 내지 90°의 각도가 되게 하여 중첩하고 그 교차점을 열접착하거나 접착제로 접착 결합한 부직포는 경사상면으로만 위사가 중첩 결합되어 있어서 경사와의 결합상태가 약하여 결국 경·위사가 이탈되기 쉬울뿐 아니라 열융착시에는 경·위사 자체의 용융결착이므로 교차점의 결착표면적이 적어 결착력이 약한 등의 결함이 있었다.Conventional nonwoven fabrics are prepared by adhering staple fibers into a web and bonding the fibers together with an adhesive, or by threaded orthogonal yarns orthogonally, or a continuous series of reticulated nets interconnected by a plurality of fine fibers. Two layers of the object of parallel monofilament are superimposed on each other at an angle of 20 ° to 90 ° to thermally bond the intersection points (e.g., Japanese Utility Model Publication No. 54-139783) There were nonwoven fabrics made by adhesive bonding, but nonwoven fabrics made of staple fibers have weak strength in the light and upper direction, and have weaknesses in wet strength because they bond fibers together as adhesives, and light and weft yarns are bonded orthogonally. The nonwoven fabric has a dimensional stability in the direction of the warp and pseudo yarn, but has no elasticity, and thus has a defect that the intersection point of the warp and the warp yarn is easily detached due to tension or impact. Nonwoven fabrics in which the two monofilament layers of the object are overlapped with each other at an angle of 20 ° to 90 °, and the intersection points are thermally bonded or adhesively bonded with an adhesive are overlapped and bonded to the warp yarn only by the inclined top surface. As the bonding state is weak, the hard and weft yarns are easily separated, and at the time of heat fusion, the hard and weft yarns are melted together.
본 고안은 이와 같은 재결함을 해소하기 위하여 경사군을 중심으로 하여 그 상·하면에 위사군을 사각(斜角)으로 교차시키고 교차 부분을 결착시키되 결착표면적을 크게 함으로써 경·위사의 결착력을 강화하고 또 경사를 직선으로 하여 길이방향으로의 칫수 안정성을 기하고 2조의 위사군은 사각을 형성케 함으로써 다소의 신축성을 갖도록 하여 인장과 충격에 강한 부직포를 고안한 것으로 도면에 따라 더욱 상세히 설명하면 다음과 같다.The present invention reinforces the binding strength of light and weft yarns by intersecting the weft groups squarely on the upper and lower sides of the inclined group and binding the intersecting parts while increasing the binding surface area in order to solve such defects. In addition, the inclination is a straight line to ensure the dimensional stability in the longitudinal direction, and two sets of weft groups have a non-woven fabric that is strong in tension and impact by forming a square to have some elasticity. Same as
제1도는 본 고안의 평면도로서 (1)은 경사이고 (2)(3)은 서로 사교(斜交)하는 위사군이다.1 is a plan view of the present invention, where (1) is inclined and (2) and (3) are weft groups that cross each other.
제2도는 제1도의 A-A선 절단단면도로서 경사(1)의 상·하면에 위사 (2)(3)이 결착되어 있음을 알 수 있다.FIG. 2 is a cross-sectional view taken along the line A-A of FIG. 1, and it can be seen that the weft yarns 2 and 3 are attached to the upper and lower surfaces of the inclination 1. FIG.
제3도는 본 고안의 경·위사가 교차하고 있는 부분의 확대도로서 경사 (1)을 중심으로 위사(2)(3)이 사교(斜交)하고 있음을 알 수 있다.3 is an enlarged view of a portion where the light and weft yarns of the present invention intersect, and it can be seen that the weft yarns 2 and 3 are interlaced with respect to the inclination 1.
본 고안에서는 경·위사 접착방법으로 경사군과 같은 폭의 폴리에칠렌 필름 또는 이와 유사한 열융착가능한 필름 등 저융점 열용융성 접착제를 경사군위 또는 아래에 적층하고 그 위에 위사군을 사교 적층하여 가열 가압하여 접착제를 열융착(도시되어 있지 않음)시킴으로써 실들을 교차부에 견고하게 결착시킴과 동시에, 이때 실과 실의 공간부분에 해당하는 필름은 경, 위사의 교차점을 둘러싸면서 수축 응고되어 실과 실의 결착을 견고히 하였다In the present invention, a low-melting-point hot melt adhesive such as a polyethylene film or a similar heat-sealable film having the same width as the warp warp layer is laminated on or below the warp warp by heat-weft warp, By heat-sealing the adhesive (not shown), the yarns are firmly bound to the intersections, and at this time, the film corresponding to the spaces of the yarns and the yarns shrinks and solidifies around the intersection point of the light and weft yarns to prevent the yarns from being bound. Solidified
필름 접착방법이 아닐 때에는 용제형 접착제 또는 핫트멜트형 접착제를 사용하므로서 습윤 강도를 높일수 있다.When the film is not bonded, the wet strength can be increased by using a solvent adhesive or a hot melt adhesive.
다만, 본 고안에서 저융점 열용융성 접착제라 함은 경, 위사의 융점보다 그 융점이 낮은 것을 말하며, 그럼으로써 접착제 용융시 경, 위사가 열에 의하여 취약화됨을 방지할 수 있게 할 수 있다.However, in the present invention, the low melting point hot melt adhesive means that the melting point is lower than that of the light and weft yarns, so that when the adhesive is melted, it is possible to prevent the wefts from being weakened by heat.
이와 같이 구성된 본 고안은 경사군이 직선상이므로 길이방향으로 칫수 안정성이 우수하고 위사 방향으로는 신축성이 있어 충격강도가 강하며 실 교차부분의 접착표면적을 크게 하였으므로 실 상호간의 접착력이 강하여 전체적인 부직포의 강력이 큰 특징이 있어 본 고안의 단독 사용은 물론 크라프트지에 폴리에칠렌 필름으로 가열 가압 접착하여 시멘트, 비료 등 중포장물의 포장용으로 사용할 수 있고 폴리에칠렌으로 양면 코오팅하면 천막지로서 사용할 수 있는 등 각종 산업용 보강제로서 실용적인 고안이다.Since the inclined group is straight, the present invention is constructed in such a way that the dimension stability in the longitudinal direction is excellent and the elasticity in the weft direction is strong, and the impact strength is increased. It is characterized by its powerful features, and can be used for packing heavy packing materials such as cement and fertilizer by heat and pressure-bonding to a kraft paper with a polyethylene film, and can be used as a tent paper when double-coated with polyethylene. As a practical design.
