Description

농업용 부직포{Agricultural sheet}Agricultural nonwovens {Agricultural sheet}

본 발명은 토양산성화 방지 및 잡초성장억제를 위한 농업용 부직포의 개량에 관한 것으로서, 특히 부직포를 토양상부에 덮어 씌워 잡초의 성장을 억제하되, 부직포의 두께를 가장 이상적인 두께로 하여 원활한 공기유통이 이루어지게 하므로서 토양에 식재된 농작물의 성장을 촉진케 함과 동시에 미생물의 증식을 도와 토양의 산성화현상을 방지할 수 있도록 한 것이다.The present invention relates to the improvement of agricultural nonwoven fabrics for preventing soil acidification and inhibiting weed growth. In particular, the nonwoven fabric is covered with an upper portion of the soil to suppress weed growth, but the nonwoven fabric thickness is the most ideal thickness for smooth air distribution. Therefore, it promotes the growth of crops planted in the soil and at the same time helps the growth of microorganisms to prevent acidification of the soil.

일반적으로 각종 농작물이 식재된 토양 상부에는 여러형태로 제공되고 있는 부직포를 덮어 씌워 잡초의 성장을 억제케 하고, 식재된 농작물은 성장을 촉진케 하는 수단으로 널리 사용되고 있다.In general, cover the non-woven fabric provided in various forms on the top of the soil planted with various crops to suppress the growth of weeds, planted crops are widely used as a means to promote growth.

한예로서 합성섬유 필라멘트사를 이용하여 부직포를 제조하되, 상기 부직포 일측면에 부분적으로 열압착엠보싱 처리되게 한 부직포가 제공된 바 있으나 엠보싱이 일측면에만 처리되어 있을 뿐 아니라 두께가 비교적 두꺼워 원활한 공기유통이 곤란하여 수분함량이 과다하기 때문에 잡초가 녹아 내리고, 농작물의 성장에도 장애가 되며, 특히 공기유통의 곤란성 때문에 각종 미생물의 생장번식이 억제되어 오히려 토양을 산성화시키게 되는 단점이 있었다.As an example, a non-woven fabric is manufactured by using a synthetic fiber filament yarn, but a non-woven fabric is provided that is partially thermocompressed embossed on one side of the nonwoven fabric, but the embossing is not only processed on one side but also relatively thick, so that a smooth air circulation Due to the excessive moisture content, the weeds melt and hinder the growth of crops, and in particular, due to the difficulty of air circulation, the growth and propagation of various microorganisms is suppressed, so that the soil is acidified.

이러한 문제점들을 보완하기 위하여 특허 제248939호 "토양산성화 방지 및 잡초성장 억제용 부직포"로 특허된 부직포가 제공된 바 있다.In order to compensate for these problems, a nonwoven fabric has been provided with a patent No. 248939 "Nonwoven fabric for preventing soil acidification and weed growth inhibition".

즉 2.8∼3.2데니어 합성섬유사 수천가닥을 다소 큰 반경으로 회전시키면서 고른 두께로 분포되게 한 다음 열압착하여 부직포를 구성함과 동시에 부직포 상에 엠보싱처리하되, 엠보싱의 폭은 약0.5mm이고, 각 엠보싱간의 간격은 약1mm 정도로 한 통상의 부직포에 있어서, 부직포에 처리되는 엠보싱은 표면과 이면에 동일한 위치로 형성되게 하고, 부직포의 두께는 약0.8∼1.5mm정도 유지되게 하여서 된 부직포인 것이다.That is, thousands of 2.8 ~ 3.2 denier synthetic fiber yarns are rotated to a rather large radius and distributed evenly, and then thermocompressed to form a nonwoven fabric and embossed on the nonwoven fabric, with an embossing width of about 0.5mm. In a conventional nonwoven fabric having an interval between embossings of about 1 mm, the embossing processed on the nonwoven fabric is a nonwoven fabric which is formed at the same position on the front and back surfaces, and the thickness of the nonwoven fabric is maintained at about 0.8 to 1.5 mm.

따라서 상기한 구성의 부직포는 엠보싱이 부직포의 양측면에 동시에 형성되어 있어 동일한 두께의 부직포와 비교한다면 적당한 강도와 형태유지의 용이성이 있고, 또한 엠보싱의 요철부에 의해 공기와의 접촉면적이 그만큼 커지게 되므로 공기유동이 원활하게 이루어지게 되는 등의 효과가 있으나, 부직포의 두께가 비교적 두꺼운 관계로 최적의 공기유통은 이루어지지 못하게 되는 등의 단점이 있는 것이었다.Therefore, the nonwoven fabric of the above-described configuration is embossed on both sides of the nonwoven fabric at the same time, and compared with the nonwoven fabric of the same thickness, so that the moderate strength and ease of shape maintenance, and the uneven portion of the embossing has a large contact area with air Therefore, there is an effect such that the air flow is made smoothly, but because the thickness of the nonwoven fabric is relatively thick, the optimum air flow was not made.

본 발명은 부직포의 사용목적에 만족하면서 최적의 원활한 공기유통이 이루어질 수 있게 한 부직포를 제공하고자 하는 것이다.It is an object of the present invention to provide a nonwoven fabric capable of achieving an optimal smooth air distribution while satisfying the purpose of use of the nonwoven fabric.

부직포에 있어서 중요한 조건은 부직포의 사용시 토양에 생성된 잡초는 성장을 억제케 하되, 적량의 공기가 유통되어 토양에 잔존하는 미생물이나 식재된 농작물의 번식 및 성장에는 아무런 장애가 되지 않도록 하여야 하는 것이며, 이러한 조건은 부직포의 밀도와 그 밀도에 따른 두께가 이를 결정하게 된다.An important condition for nonwoven fabrics is that weeds produced in the soil when the nonwoven fabric is used should be inhibited from growth, but an adequate amount of air is distributed to prevent the growth and growth of microorganisms or planted crops remaining in the soil. The condition is determined by the density of the nonwoven fabric and its thickness.

실험한 바에 의하면 부직포의 두께가 0.3mm이하일 경우에는 부직포의 두께가 너무 얇아 형상보존 및 잘 찢어지게 되므로 취급에 어려움이 있고, 또한 차광능력이 낮고 과다한 공기유통으로 인하여 잡초의 성장억제에 거의 도움이 되지 못하게 되므로 사용에 문제가 있게 된다.According to the experiment, when the thickness of the nonwoven fabric is less than 0.3mm, the thickness of the nonwoven fabric is so thin that it is difficult to handle because of its shape preservation and tearing, and it is hard to handle the growth of weeds due to low shading ability and excessive air distribution. There is a problem with using it.

반대로 부직포의 두께가 0.6mm이상일 경우에는 부직포의 강도와 형태유지능력이 우수하여 취급성은 양호하나, 두꺼운 관계로 차광능력이 높아 농작물의 잔뿌리가 부직포를 토양으로 오인하여 뿌리를 내리게 되므로 날씨가 건조하게 되면 농작물이 말라 피해를 가중시키게 되며, 또한 공기유통이 미흡하여 토양에 생존하는 미생물의 번식이 억제되어 산성화 현상을 유발케 되므로 역시 문제가 있는 것이다.On the contrary, when the thickness of the nonwoven fabric is more than 0.6mm, the handleability is good because of the strength and shape-keeping ability of the nonwoven fabric, but the weather is dry because the roots of crops are mistaken for the nonwoven fabric as the soil due to its thick shading ability. If the crops dry up, the damage is increased, and air circulation is insufficient, so that the growth of microorganisms that survive in the soil is suppressed, causing acidification, which is also a problem.

본 발명은 이러한 제반 문제점을 시정보완하여 보다 이상적인 최적의 부직포를 제공하고자 하는 것이다.The present invention seeks to provide a more ideal optimum nonwoven fabric by solving these problems.

상기 목적을 달성하기 위하여 본 발명은 2∼3데니어 굵기의 합성섬유 필라멘트사 수천가닥을 자유낙하시켜 여러겹 고르게 분포되게 한 다음 부직포의 일면 또는 양면에 열압착프레스로 열압하여 일정한 간격으로 엠보싱 처리되게 하되, 부직포의 밀도가 m2당 약55∼65g으로 하고 두께를 약0.3∼0.6mm정도 되게 한 것이다.In order to achieve the above object, the present invention freely falls thousands of strands of synthetic fiber filament yarn of 2-3 denier thickness and distributes them evenly in several layers, and is then embossed at regular intervals by hot pressing on one or both sides of the nonwoven fabric. However, the density of the nonwoven fabric is about 55-65g per m 2 and the thickness is about 0.3-0.6mm.

이하 본 발명의 실시예를 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에서 제공하고자 하는 부직포(2)의 평면구성도로서, 부직포(2)의 본체 상에 프레스롤러로 열압착하여 적절한 간격으로 엠보싱되게 한 상태이고, 도 2는 상기 부직포(2)를 절단한 상태의 개략적인 단면구성도이다.1 is a plan view of the nonwoven fabric 2 to be provided in the present invention, which is a state in which a pressing roller is embossed at an appropriate interval on a main body of the nonwoven fabric 2, and FIG. 2 is the nonwoven fabric 2. Is a schematic cross-sectional view of the cut state.

상기한 구성의 부직포(2)를 제조하는 과장을 상세히 설명하면, 합성섬유 필라멘트사 수천가닥을 자유낙하시켜 고른 밀도를 분포되게 한 다음 프레스롤러로 열압착하여 양면 동일한 위치에 엠보싱(4) 되게 하므로서 상대적으로 엠보싱(4) 되지 아니한 벌키부(6)가 구성되게 한다.When explaining the exaggeration of manufacturing the nonwoven fabric 2 of the above-described configuration in detail, by thousands of strands of synthetic fiber filament yarn freely distributed to distribute the even density, and then heat-compressed with a press roller to be embossed (4) at the same position on both sides The bulky part 6 which is relatively not embossed 4 is made.

이때 부직포(2)에 구성되는 엠보싱(4)의 면적은 부직포(2) 전체면적에 20∼30% 정도 형성되게 하므로서 부직포(2) 상에 적당한 강도와, 형태유지 및 원활한 공기유통이 이루어지게 한다.At this time, the area of the embossing (4) constituted in the nonwoven fabric (2) is about 20 to 30% formed in the total area of the nonwoven fabric (2), so that the appropriate strength, shape maintenance and smooth air flow on the nonwoven fabric (2) is achieved. .

상기에서 부직포(2) 상에 열압착되는 엠보싱(4)의 크기는 가로세로 폭이 0.4∼0.6mm정도이고, 엠보싱(4) 간의 간격은 0.9∼1.1mm정도로 하는 것이 이상적이다.It is ideal that the size of the embossing 4 thermocompressed on the nonwoven fabric 2 is about 0.4 to 0.6 mm in width and width, and the spacing between the embossings 4 is about 0.9 to 1.1 mm.

이때 부직포(2) 상에 처리되는 엠보싱(4)의 형태는 제한받지 아니하나 부직포(2) 전체면적에 약20∼30% 정도 고른 간격으로 엠보싱되게 하면 된다.At this time, the shape of the embossing (4) to be processed on the nonwoven fabric 2 is not limited, but may be embossed at even intervals about 20 to 30% to the entire area of the nonwoven fabric (2).

상기에서 제조되는 부직포(2)의 밀도 및 두께는 밀도가 약55∼65g/m2이고,두께가 약0.3∼0.6mm정도로 하는 것이 최적상태의 공기유통과 동시에 적절한 빛차광이 되어 부직포(2)의 사용목적이 가장 적합한 상태의 제품을 제공받을 수 있게 된다.The density and thickness of the nonwoven fabric 2 prepared above are about 55 to 65 g / m 2 , and the thickness is about 0.3 to 0.6 mm. The purpose of using the product is to provide the product in the most suitable state.

이와 같이 구성된 본 발명의 부직포(2)는 각종 농작물이 식재된 토양 상부에 덮어 씌워 잡초의 성장을 억제하고, 적절한 공기유통이 이루어지게 하여 토양에 잔존하는 미생물의 증식을 도와 산성화 현상을 방지하고, 또한 농작물의 뿌리에도 적당량의 공기를 유동시켜 성장을 촉진케 한다는 것은 종래와 같으나 본 발명에서 제공하는 부직포(2)는 부직포(2)의 본체 표면에 적절한 비율로 엠보싱(4)이 구성되게 하면서 밀도가 약55∼65g/m2, 두께가 약0.3∼0.6mm정도로 유지케 하므로서 부직포의 사용목적을 충족하면서 최적상태의 공기가 유통되게 하여 이상적인 부직포(2)를 제공받을 수 있게 된다.Nonwoven fabric (2) of the present invention configured as described above is covered with the top of the soil planted with various crops to suppress the growth of weeds, and to make the appropriate air distribution to help the growth of microorganisms remaining in the soil to prevent acidification phenomenon, In addition, to promote growth by flowing an appropriate amount of air to the roots of the crop as in the prior art, the nonwoven fabric 2 provided in the present invention has a density while allowing the embossing 4 to be formed at an appropriate ratio on the surface of the main body of the nonwoven fabric 2. It is maintained at about 55 ~ 65g / m 2 , the thickness of about 0.3 ~ 0.6mm, while meeting the purpose of use of the nonwoven fabric to ensure that the air in the optimum state can be provided to the ideal nonwoven fabric (2).

즉 부직포의 두께가 0.3mm이하일 경우에는 강도가 취약하여 취급과 사용이 곤란할 뿐 아니라 빛의 차단이 미흡하고, 공기유통이 과다하여 잡초성장억제에 도움이 되지 못하게 되며, 반대로 부직포의 두께가 0.6mm이상일 때에는 빛의 차단이 과다하여 잡초성장억제효과는 있으나 공기유통이 미흡하여 토양에 존재하는 미생물의 번식을 억제하게 되므로 토양의 산성화 현상을 가중시키게 되며, 특히 농작물의 잔뿌리가 부직포에 내리게 되어 가뭄시 작물이 말라죽는 현상이 심화되나, 본 발명에서와 같이 부직포의 밀도가 약55∼65g/m2, 두께가 약0.3∼0.6mm정도 유지케 하므로서 잡초의 성장을 효과적으로 억제하면서 적량의 공기가 유통케 하므로서 토양에존재하는 미생물의 배양에도 아무런 문제가 없게 되므로 산성화 현상을 방지하고, 동시에 작물의 뿌리에는 충분한 산소공급이 이루어지게 하여 이상적인 작물재배가 이루어질 수 있게 된다.In other words, when the thickness of the nonwoven fabric is less than 0.3mm, the strength is weak, which makes it difficult to handle and use, and the light blocking is insufficient, and the air flow is excessive to prevent weed growth. When abnormal, blockage of light is excessive, weed growth suppression effect is ineffective, but air circulation is insufficient, which inhibits the growth of microorganisms present in soil, which increases acidification of soil. The dryness of the crop is intensified, but as in the present invention, the nonwoven fabric has a density of about 55 to 65 g / m 2 and a thickness of about 0.3 to 0.6 mm, thereby effectively suppressing the growth of weeds while allowing an appropriate amount of air to flow. Therefore, there is no problem in cultivation of microorganisms existing in the soil, thus preventing acidification and at the same time Is able to be an ideal crop to be a sufficient supply of oxygen carried.

따라서 본 발명은 농업용 부직포를 구성함에 있어서 밀도가 약55∼65g/m2, 두께가 약0.3∼0.6mm정도로 구성되게 하므로서 부직포의 사용목적을 충족하면서 최적상태의 공기가 유통되게 하여 보다 이상적인 부직포를 제공받을 수 있게 되는 등의 효과가 있는 것이다.Therefore, in the present invention, the agricultural nonwoven fabric has a density of about 55 to 65 g / m 2 , and a thickness of about 0.3 to 0.6 mm, while satisfying the purpose of using the nonwoven fabric so that the air in an optimal state is circulated, thereby providing a more ideal nonwoven fabric. The effect is that it can be provided.
