Description
본 발명은 인장강도가 보강된 부직포 및 그 보강방법에 관한 것으로서, 보다 상세하게는 지반공사 등과 같은 토목건설 분야에서 토사의 배수 또는 필터링 등의 수리적 용도로 사용되는 부직포의 강도특성을 개선시키기 위한 방법에 관한 것이다.The present invention relates to a nonwoven fabric reinforced with tensile strength and a reinforcing method thereof, and more particularly, a method for improving the strength characteristics of a nonwoven fabric used for hydraulic applications such as draining or filtering soil in a civil construction field such as ground works. It is about.
부직포(Non-woven fabric)란 폴리프로필렌 또는 폴리에에스터 등으로된 미세사를 단독 또는 혼합한 상태로 압착 처리하여 섬유재로 제조한 후 이를 니들펀칭(Needle punching) 등의 방법으로 다수의 통공을 형성시킨 기능성 섬유를 말하는 것으로, 일반적으로 부직포가 갖는 투수기능을 이용하여 지반공사 등과 같은 대규모 토목공사시 토사등과 같은 수분함유 고형물의 배수를 위한 필터링 등의 용도로서 널리 이용되고 있다.Non-woven fabrics are made of a fiber material by compressing the fine yarns made of polypropylene or polyester alone or in a mixed state, and then manufacturing a plurality of through-holes by needle punching. It refers to the functional fiber formed, and is generally used as a filter for drainage of water-containing solids such as soil and sand during large-scale civil engineering works such as ground works by using the permeation function of the nonwoven fabric.
그러나 상기의 부직포는 구조적 특성상 일반 직물섬유와 비교하여 인장강도 등의 물리적 특성이 매우 약할 뿐만 아니라, 신율이 높아서 장기간의 공사 기간을 요하는 대규모의 공사시에는 토사 등과 같은 수분함유 고형물의 자체 하중에 의한 지속적인 응력 인가로 인하여 부직포가 쉽게 이완되어 변형되고, 아울러 부직포에 구성된 통수공의 구경이 확대됨으로서 효과적인 필터링이 이루어지지 못하게 되어 부직포의 기본 기능인 배수기능 등의 수리적 특성이 급격하게 저하되는 현상이 발생하였으며, 이와 같은 부직포의 수리적 특성 저하현상으로 인하여 공사시 설치한 부직포 구조물을 경우에 따라 다수회에 걸쳐 재설치하여하는 번거로움이 발생하였을 뿐만 아니라 공사 기간이 지연되고 공사 비용 또한 크게 증가함과 아울러 궁극적으로는 전반적인 공사품질을 크게 저하시키는 문제점이 있었다.However, the nonwoven fabric is not only weak in physical properties such as tensile strength, but also high in elongation due to its structural characteristics. Due to the continuous stress applied, the nonwoven fabric is easily relaxed and deformed, and the diameter of the water hole formed in the nonwoven fabric is enlarged, so that effective filtering cannot be achieved, and the hydraulic characteristics such as the drainage function, which is the basic function of the nonwoven fabric, sharply deteriorate. In addition, due to the deterioration of the hydraulic properties of the nonwoven fabric, not only has the trouble of re-installing the nonwoven fabric structure installed at a time in many cases, but also delays the construction period and greatly increases the construction cost and ultimately. In the first half The quality of the construction there is a problem that greatly reduced.
본 발명은 상기 언급한 제반 문제점을 해결하기 위한 것으로서, 토목건설분야에서 필터링 및 배수 기능을 수행하는 토목공사용 기능성 섬유중 가장 광범위하게 사용되고 있는 부직포의 강도 특성 및 신율 등의 제반 물성을 크게 개선함으로서, 공사기간이 장기화됨에 따라 외부응력의 작용에 의해 부직포 섬유가 이완됨으로 인하여 부직포 내에 구성된 통수공의 확대에 의한 수리적 특성 저하를 방지할 수 있는 인장강도가 보강된 부직포 및 그 보강방법을 제공함에 그 목적이 있다.The present invention is to solve the above-mentioned problems, by greatly improving the overall physical properties, such as strength characteristics and elongation of nonwoven fabrics most widely used among civil engineering functional fibers performing filtering and drainage in the field of civil construction, The purpose of the present invention is to provide a nonwoven fabric reinforced with tensile strength and a method of reinforcing the same to prevent the deterioration of the hydraulic characteristics due to the expansion of the water hole formed in the nonwoven fabric due to the relaxation of the nonwoven fabric by the action of external stress as the construction period is prolonged. There is this.
도 1은 본 발명의 일 실시예를 나타낸 사시도1 is a perspective view showing an embodiment of the present invention
＜도면의 주요부분에 대한 부호의 설명＞<Description of the code | symbol about the principal part of drawing>
1 : 부직포 2 : 길이방향보강사1: nonwoven fabric 2: longitudinal reinforcement yarn
3 : 폭방향보강사 4 : 봉제사3: width reinforcement yarn 4: sewing thread
상기한 목적을 달성하기 위한 본 발명은 일종 이상의 합성섬유사를 단독 또는 혼합한 상태로 압착한 후 니들펀칭하여 제조된 부직포에 있어서, 1000 데니르(denier)이상의 굵기를 갖는 섬세사로 이루어진 보강사가 부직포의 표면에 일정한 간격으로 연속적으로 봉제(stitching)처리되어 있음을 특징으로 하는 인장강도가 보강된 부직포를 제공한다.The present invention for achieving the above object is a nonwoven fabric manufactured by needle punching after pressing at least one type of synthetic fiber yarn alone or in a mixed state, the reinforcing yarn made of a fine yarn having a thickness of 1000 denier (denier) or more non-woven fabric It provides a non-woven fabric reinforced with tensile strength, characterized in that the surface of the surface is continuously stitched (stitching) at regular intervals.
또한, 본 발명은 일종 이상의 합성섬유사를 단독 또는 혼합한 상태로 압착한 후 니들펀칭하여 제조된 부직포(1)의 표면에 1000 데니르(denier)이상의 굵기를 갖는 섬세사로 이루어진 길이방향보강사(2)를 5 내지 25mm 간격으로 연속적으로 구성한 후, 그 상부에 1000 데니르(denier)이상의 굵기를 갖는 섬세사로 이루어진 폭방향보강사(3)를 5 내지 25mm 간격으로 연속적으로 적층하여 구성한 상태에서 봉제사(4)로 상기 폭방향보강사(3)를 봉제(stitching)처리함을 특징으로 하는 부직포의 보강방법을 제공한다.In addition, the present invention is a longitudinal reinforcing yarn made of a delicate yarn having a thickness of at least 1000 denier (denier) on the surface of the non-woven fabric (1) prepared by pressing a single or more synthetic fiber yarns alone or in a mixed state (needle punching) ( 2) continuously composed at intervals of 5 to 25 mm, and the sewing thread in a state in which a widthwise reinforcement yarn (3) consisting of fine yarns having a thickness of 1000 deniers or more is stacked on the upper portion continuously at intervals of 5 to 25 mm. (4) provides a method for reinforcing a nonwoven fabric, characterized in that the stitching treatment of the widthwise reinforcement (3).
본 발명의 부직포 제조시에 사용되는 섬유사의 원료로는 다양한 종류의 합성섬유사를 단독 또는 혼합하여 사용할 수 있으나, 원료확보가 용이하고 가격이 저렴하며 신율, 강도 등의 측면에서 양호한 특성을 나타내는 폴리프로필렌 또는 폴리에스터로된 섬유사를 혼합 사용함이 바람직하며, 이러한 섬유원료를 통상적인 부직포 제조방법에 의하여 혼합한 후 압착처리하고 니들펀칭 처리하게 되면 다수의 통공이 형성된 부직포를 제조할 수 있는 것이다.As a raw material of the fiber yarn used in the manufacture of the nonwoven fabric of the present invention, various kinds of synthetic fiber yarns may be used alone or mixed, but the material is easy to secure, low in cost, and exhibits good properties in terms of elongation and strength. It is preferable to use a fiber yarn made of propylene or polyester, and such a fiber material may be mixed by a conventional nonwoven fabric manufacturing method and then compressed and needle punched to produce a nonwoven fabric having a plurality of holes.
상기한 바의 일반적인 방법에 의하여 제조된 부직포의 표면에 보강사를 구성한 후 봉제사로 봉제(stitching)처리하게 되는데, 이때 사용되는 보강사는 1000데니르 이상의 굵기를 갖는 섬세사를 통상적인 방법으로 스피닝(spinning)하여 이루어진 합성섬유사로서 재질의 종류에는 무관하나 강도가 높은 것일수록 바람직하며, 섬세사의 굵기가 1000데니르 이하로 되면 섬세사 자체의 강도가 낮아져 이를 스피닝하여 제조되는 보강사의 굵기를 상대적으로 더욱 크게 하여야하는 문제점이 발생한다.After forming a reinforcing yarn on the surface of the non-woven fabric prepared by the general method as described above is stitched with a sewing yarn, the reinforcing yarn used is spinning the fine yarn having a thickness of 1000 denier or more in a conventional manner ( The synthetic fiber yarns made by spinning) are irrelevant to the type of material, but the higher the strength, the more preferable. When the thickness of the fine yarn is less than 1000 denier, the strength of the delicate yarn itself is lowered, so that the thickness of the reinforcement yarn manufactured by spinning the yarn is relatively smaller. There is a problem that must be made larger.
이러한 보강사를 부직포의 표면에 일측 이상의 방향으로 일정간격을 두고 반복적으로 다수회에 걸쳐 봉제처리함으로서 부직포의 인장강도 보강효과를 얻을 수 있는 것이며, 이때 부직포의 표면에 구성된 보강사의 간격이 5mm 이하로 조밀하게 구성되면 인장 강도는 크게 증가시킬 수 있으나 부직포의 표면에 구성된 통공의 면적밀도를 감소시켜 부직포가 갖는 통수기능 등의 수리적 특성을 저하시키는 문제점이 발생할 수 있고 25mm이상으로 구성될 경우에는 바람직한 인장강도의 보강효과를 얻을 수 없는 문제점이 있으므로 보강사의 간격은 5 내지 25mm로 함이 바람직하다.The reinforcing yarns are sewn repeatedly several times with a predetermined interval on the surface of the nonwoven fabric in a direction more than one side to obtain the tensile strength reinforcing effect of the nonwoven fabric, wherein the thickness of the reinforcing yarns formed on the surface of the nonwoven fabric is less than 5mm If it is densely constructed, the tensile strength can be greatly increased, but the area density of the pores formed on the surface of the nonwoven fabric can be reduced, which may cause a problem of deteriorating the hydraulic characteristics such as the water permeation function of the nonwoven fabric. Since there is a problem in that the reinforcing effect of strength cannot be obtained, the spacing of the reinforcing yarn is preferably 5 to 25 mm.
상기한 바와 같이 부직포의 표면에 봉제처리되는 보강사는 부직포의 일측 이상의 방향, 예를들면 부직포의 길이방향, 폭방향 또는 대각방향 등의 여러방향으로 중복 구성될 수 있으나, 재료비나 공정비용 등의 생산원가를 고려하여 상기 보강사를 부직포의 길이방향 및 폭방향만으로 교차하여 구성하는 경우에도 소기한 바의 인장강도 보강효과를 얻을 수 있다.As described above, the reinforcing yarns sewn on the surface of the nonwoven fabric may be overlapped in one or more directions of the nonwoven fabric, for example, in the longitudinal direction, the width direction, or the diagonal direction of the nonwoven fabric, but the production of material costs, process costs, etc. Considering the cost, even when the reinforcing yarns are constructed to cross only the nonwoven fabric in the longitudinal direction and the width direction, the desired tensile strength reinforcement effect can be obtained.
즉, 도 1에 도시된 바와 같이 상기 언급된 통상적인 방법에 의하여 제조된 부직포(1)의 표면에 1000 데니르(denier)이상의 굵기를 갖는 섬세사로 이루어진 길이방향보강사(2)를 5 내지 25mm 간격으로 반복적으로 구성한 후, 그 상부에 1000 데니르(denier)이상의 굵기를 갖는 섬세사로 이루어진 폭방향보강사(3)를 5 내지 25mm반복적으로 구성하는 경우에도 인장강도가 현저하게 개선될 수 있는 것이다.That is, as shown in FIG. 1, 5 to 25 mm of longitudinal reinforcement yarn 2 made of fine yarn having a thickness of 1000 denier or more on the surface of the nonwoven fabric 1 manufactured by the above-mentioned conventional method. After repeated configuration at intervals, the tensile strength can be remarkably improved even if the widthwise reinforcing yarn (3) consisting of delicate yarn having a thickness of 1000 denier or more on the top 5 to 25mm repeatedly .
이때 상기 길이방향보강사(2)와 폭방향보강사(3)를 부직포(1)의 표면에 고정시키기 위하여 봉제사로 봉제처리하게 되는데, 길이방향보강사(2) 및 폭방향보강사(3) 모두를 봉제처리할 경우 봉제공정에 소요되는 비용이 상승하여 제조원가가 높아지는 문제가 있으므로, 본 발명에서는 길이방향보강사(2)를 부직표(1)의 표면에 5 내지 25mm 간격으로 반복적으로 구성한 후, 그 상부에 폭방향보강사(3)를 5 내지 25mm 간격으로 반복적으로 적층하여 구성한 상태에서 봉제사(4)로 상기 폭방향보강사(3)만을 봉제(stitching)처리함으로서 보다 경제적인 방법으로 인장강도가 보강된 부직포를 제조할 수 있었다.At this time, the longitudinal reinforcing yarn (2) and the widthwise reinforcing yarn (3) is sewn with a sewing thread to fix the surface of the nonwoven fabric (1), longitudinal reinforcing yarn (2) and widthwise reinforcing yarn (3) In case of sewing all of them, there is a problem that the manufacturing cost increases due to an increase in the cost of the sewing process. In the present invention, the longitudinal reinforcing yarn 2 is repeatedly formed on the surface of the nonwoven table 1 at intervals of 5 to 25 mm. In a state in which the widthwise reinforcing yarns 3 are repeatedly stacked on the upper portion thereof at intervals of 5 to 25 mm, the stitching process is performed by stitching only the widthwise reinforcing yarns 3 with a sewing thread 4 to obtain tensile strength in a more economical manner. It was possible to produce a nonwoven fabric with reinforced strength.
