Description

Translated fromKorean
멀칭용 부직포 구조체 {NONWOVEN STRUCTURE FOR MULCHING}Nonwoven Structure for Mulching {NONWOVEN STRUCTURE FOR MULCHING}

본 발명은 우수한 액체 비료 투과성 및 자외선 차단성을 나타내는 멀칭용 부직포 구조체에 관한 것으로, 더욱 자세하게는 카딩에 의해 얻어지는 열융착 혹은 니들펀칭 부직포를 다공성 폴리비닐클로라이드(PVC) 접합 필름을 사이에 두고 합포하여 제조된 샌드위치형 부직포 구조체가 적용되어 높은 자외선 차단율을 제공하여 멀칭된 농토에서의 잡초 생장을 효과적으로 억제하며, 액체 비료의 투입이 가능하고, 높은 인장 강도를 보유하여 작물의 생장 기간 동안 찢김에 의한 파손을 방지할 수 있는 멀칭용 부직포 구조체에 관한 것이다.The present invention relates to a non-woven fabric structure for mulching exhibiting excellent liquid fertilizer permeability and UV-blocking properties, and more specifically, a heat-sealed or needle punched non-woven fabric obtained by carding is laminated with a porous polyvinyl chloride (PVC) bonding film interposed therebetween. The sandwich-type nonwoven fabric is applied to provide high UV-blocking rate, which effectively inhibits weed growth in mulched farmland, enables the introduction of liquid fertilizer, and retains high tensile strength. It relates to a non-woven fabric structure for mulching that can prevent.

여러 층의 부직포를 적층하거나 두꺼운 웹으로부터 성형하는 농업용 부직포는 기존 PVC 필름 제품에 비해 그 두께가 두터운 편인데, 경우에 따라 작물이 부직포를 토양으로 인식하여 잔뿌리를 뻗음으로써 가물이 발생하는 경우 쉽게 고사하는 문제점이 있다. (대한민국 특허등록 제 10-0248939호)Agricultural nonwoven fabrics that are laminated with multiple layers of non-woven fabric or formed from thick webs are thicker than conventional PVC film products.In some cases, crops recognize nonwovens as soil and stretch the fine roots, causing easy killing when fraud occurs. There is a problem. (Korean Patent Registration No. 10-0248939)

일반적인 농업용 부직포에 대한 실험 결과로부터 0.3mm 내지 0.6mm 두께의 부직포의 경우 가장 우수한 특성이 나타났으며, 뿌리의 들림 현상에 따른 고사를 방지하면서 적절한 공기 유통을 확보할 수 있다는 보고도 있다. (대한민국 특허등록 제 10-0562856호)From the test results for the general agricultural nonwoven fabrics showed that the non-woven fabric of the 0.3mm to 0.6mm thickness showed the most excellent characteristics, and it is also reported that it is possible to secure proper air circulation while preventing the death due to the lifting of the roots. (Korean Patent Registration No. 10-0562856)

부직포는 비닐 제품과 마찬가지로 산소공급량을 감소시킴으로써 미생물의 배양이 충분히 진행되지 않기 때문에 토양을 산성화시킨다는 보고도 있다. 또한 충분한 통기성이 보장되는 경우에도 태양광 차단이 미흡하여 일광에 의한 광합성을 통해 생장하는 잡초의 성장 억제가 용이하지 않다는 점도 문제로 지적된다. (대한민국 특허등록 제 20-0315780호)Non-woven fabrics, like vinyl products, have been reported to acidify soils by reducing the oxygen supply and not cultivating microorganisms sufficiently. In addition, it is pointed out that even when sufficient breathability is guaranteed, it is not easy to inhibit the growth of weeds growing through photosynthesis by sunlight due to insufficient solar blocking. (Korean Patent Registration No. 20-0315780)

멀칭용 재료로서 PVC 필름의 사용이 대표적인데, 이들 필름은 쉽게 파손되고 수거가 곤란하여 환경적인 문제점을 야기한다는 단점이 있으며, 이들 필름으로 멀칭된 토지에 액체 비료를 공급하는 것이 어려워 작물의 생장이 후반기에 더뎌지는 문제점이 있다.The use of PVC film as a material for mulching is typical, and these films have the disadvantage of being easily broken and difficult to collect, which causes environmental problems, and it is difficult to supply liquid fertilizer to the land mulched with these films, resulting in crop growth. There is a problem of slowing down in the second half.

최근 스펀본딩 폴리프로필렌(PP) 부직포를 적용한 멀칭용 부직포 제품이 시장에 발표되어 있으나, 스펀본드 부직포의 높은 제조 단가에 따른 고가의 제품으로 공급되고 있으며, PVC 필름에 비해 상대적으로 액체 비료의 투과성이 높기는 하지만, 식물의 생장 후기에 있어서의 성장이 더뎌지는 문제에 대해서는 충분한 해결책을 제시하지 못하고 있다.Recently, a mulching nonwoven product using spunbonded polypropylene (PP) nonwoven fabric has been announced on the market, but it is supplied as an expensive product due to the high manufacturing cost of the spunbond nonwoven fabric, and the permeability of liquid fertilizer is relatively higher than that of PVC film. Although high, it does not provide a sufficient solution to the problem of slow growth in later stages of plant growth.

합성 및 천연섬유 소재의 카딩공정에 의해 제조된 부직포 구조체의 적용성도 검토된 바 있으나, 자외선 차단율이 극히 낮아 멀칭재 하부에서의 잡초의 생장을 충분히 억제할 수 없다는 문제점이 있다.Although the applicability of the nonwoven fabric structure produced by the carding process of synthetic and natural fiber materials has also been examined, there is a problem in that the UV blocking rate is extremely low and the growth of weeds under the mulching material cannot be sufficiently suppressed.

본 발명자는 이제까지 멀칭용 소재의가 갖는 상기의 단점을 해결하고자 액체 비료의 투과도를 높이면서 자외선 투과도를 낮추기 위하여 다공성 PVC 필름을 카딩공정에 의해 제조된 부직포 사이에 위치하고 열압착하여 합포시키는 경우 자외선 차단성과 액체 비료 투과성이 우수한 멀칭용 부직포 구조체를 제조할 수 있음을 알고 본 발명을 완성하였다.In order to solve the above disadvantages of the material for mulching so far, the inventors placed a porous PVC film between non-woven fabrics prepared by a carding process to reduce UV transmittance while increasing the permeability of the liquid fertilizer to block UV rays. The present invention has been completed by knowing that it is possible to produce a non-woven fabric structure for mulching excellent in permeability and liquid fertilizer permeability.

이상의 실시예에서 볼 수 있는 바와 같이 본 발명에 의하여 제조된 멀칭용 부직포 구조체는 우수한 태양광 차단성을 가지며 접합 필름 상하의 부직포 층 두께가 0.6mm 이내로써 뿌리의 들림 현상에 따른 고사를 방지할 수 있을 뿐 아니라 다공성 접착층에 의한 통기성 및 액비 투과성을 확보할 수 있으므로 멀칭용 소재로 사용하기에 바람직하다.As can be seen in the above embodiment, the mulching nonwoven structure manufactured by the present invention has excellent sunscreen property and the nonwoven fabric layer thickness above and below the bonding film can be prevented from being killed due to the lifting phenomenon of the roots within 0.6 mm. In addition, it is preferable to use as a material for mulching because it can ensure the breathability and liquid ratio permeability by the porous adhesive layer.

본 발명은 150 내지 400 g/m2의 PP, PE 및 PET로 구성된 두 장의 부직포 사이에 0.1 내지 2.0 mm의 다공성 PVC 필름을 열압착하여 합포하는 것을 특징으로 하는 멀칭용 부직포 구조체에 대한 것이다.The present invention relates to a non-woven fabric structure for mulching, characterized in that the thermo-compression bonding of the porous PVC film of 0.1 to 2.0 mm between the two non-woven fabric consisting of 150 to 400 g / m2 PP, PE and PET.

이하, 본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 다공성 PVC 접합 필름이 적용된 멀칭용 부직포 구조체의 모식도를 보인 것으로, 합포 후 각 부직포 층 (1)과 (3)은 0.3 내지 0.6mm의 두께를 갖는 것이 바람직하다.Figure 1 shows a schematic diagram of the non-woven fabric for mulching to which the porous PVC bonding film is applied, it is preferable that each nonwoven layer (1) and (3) after the composite has a thickness of 0.3 to 0.6mm.

도 1에 있어 부직포의 합포에 사용되는 다공성 PVC 필름 (2)는 0.1 mm 이상의 두께를 갖는 것이 바람직하였는데, 그 이하의 두께에서는 부직포와의 합포 과정 중에 PVC 필름이 용융되어 자외선 차단을 위한 충분한 면적분포를 이루지 못하였으며, 2.0 mm 이상의 두께에서는 제조된 멀칭용 부직포 구조체의 두께 및 무게가 농업용으로 사용하기에 너무 무겁고 두꺼워 적합하지 않다.In FIG. 1, theporous PVC film 2 used for the nonwoven fabric is preferably at least 0.1 mm thick. At the thickness below that, the PVC film is melted during the process of lamination with the nonwoven fabric to provide sufficient area distribution for UV protection. The thickness and weight of the manufactured non-woven fabric for mulching at a thickness of 2.0 mm or more is not suitable because it is too heavy and thick for agricultural use.

도 1에 있어 다공성 PVC 필름 (2)는 1 내지 5 mm의 홀 크기를 갖는 것이 바람직하였으며, 더욱 바람직하게는 1 내지 3 mm의 홀 크기가 적합하다.In Fig. 1, theporous PVC film 2 preferably has a hole size of 1 to 5 mm, more preferably a hole size of 1 to 3 mm.

본 발명의 합포과정은 80 내지 150의 온도 범위에서 진행되었으며, 더욱 바람직하게는 100 내지 120의 온도 범위가 적합하다.The mixing process of the present invention was carried out in a temperature range of 80 to 150, more preferably a temperature range of 100 to 120 is suitable.

이하, 바람직한 실시예를 참조하여 본 발명을 더욱 상세하게 설명한다. 이하의 실시예들은 본 발명을 설명하기 위한 것으로, 이들 실시예에 의해 본 발명의 범위가 제한되는 것은 아니다.
