Description
본 발명은 미끄럼 방지용 타포린 및 그 제조방법에 관한 것으로, 보다 상세하게는, 야적물품의 보호를 위해 사용하는 천막용의 타포린을 제조하는 과정에서, 적어도 한쪽의 표면에 다수의 스플릿 얀을 소정의 간격으로 배열하면서 코팅층을형성함으로써, 표면 마찰력을 증대시켜 미끄럼에 의한 각종 안전사고를 방지할 수 있는 미끄럼 방지용 타포린 및 그 제조방법에 관한 것이다.The present invention relates to a non-slip tarpaulin and a method for manufacturing the same, and more particularly, in the process of manufacturing a tarpaulin for tents used for the protection of yard articles, a plurality of split yarns on at least one surface at predetermined intervals. The present invention relates to a non-slip tarpaulin and a method for manufacturing the same, by forming a coating layer while arranging the same, thereby increasing various surface friction and preventing various safety accidents caused by sliding.
통상적으로, 목재나 철근과 같은 건축자재나 각종 농산물 등을 야적하는 경우에는 강풍이나, 빗물, 눈으로부터 야적 물건을 보호하기 위해 천막을 덮어놓는다. 현재 방수용 천막이나 텐트의 소재로 많이 사용하고 있는 타포린은 직포의 재질에 따라서 PVC(polyvinyl chloride) 타포린과 PE(polyethylene)타포린으로 구분할 수 있다. 이중에서 PVC 타포린은 멀티필라멘트 얀으로 이루어진 PET 직포의 양면에 PVC를 코팅하여 만들며, PE 타포린의 경우에는 고밀도 폴리에틸렌(High-Density Polyethylene, HDPE)필름을 연신하여 직물(woven cloth)로 만든 다음, 이 직물의 양면에 저밀도 폴리에틸렌(Low-Density Polyethylene, LDPE)수지를 적층(laminating)하여 제조하는 것이 일반적이다.In general, in the case of building materials such as wood or reinforcing bars or various agricultural products, tents are covered to protect the objects from strong winds, rainwater and snow. Tarpaulins, which are widely used as waterproof tents and tents, can be classified into PVC (polyvinyl chloride) tarpaulin and PE (polyethylene) tarpaulin depending on the material of the woven fabric. Among them, PVC tarpaulin is made by coating PVC on both sides of PET woven fabric made of multifilament yarn, and in the case of PE tarpaulin, it is made of woven cloth by drawing high-density polyethylene (HDPE) film. It is common to manufacture by laminating low-density polyethylene (LDPE) resin on both sides of the fabric.
이들 천막용 타포린은 대부분 방수처리 되어 있어 서리가 내리거나 비나 눈이 와도 야적되어 있는 물건을 충분히 보호할 수 있으며, 바람이 불어도 쉽게 찢겨지지 않을 정도의 충분한 강도를 지니고 있다.Most of these tarpaulins for tents are sufficiently waterproof to protect items that have been stored in frost, rain or snow, and have sufficient strength not to be easily torn by wind.
그러나, 종래의 천막용 타포린은 방수성이나 강도면에서는 우수하나 표면에 미끄럼 방지처리가 되어 있지 않기 때문에, PE 타포린으로 포장된 제품을 다단으로 적재할 경우에, 도포된 LDPE 재질이 갖는 특성으로 인하여 약간의 외력에 의해서 쉽게 미끄러지는 성질 때문에, 타포린으로 포장된 제품을 다단으로 적재하는 것이 어렵게 된다. 특히, 벌목한 목재를 PE 타포린으로 덮어놓게 되면, 방수에 어려움이 있고 표면이 미끄러워 작업자들이 부상당할 우려가 있다.However, the conventional tarpaulins for tents are excellent in terms of waterproofness and strength, but they are not slippery on the surface. Due to the property of slipping easily due to the external force, it is difficult to load the product packaged with tarpaulin in multiple stages. In particular, when the felled wood is covered with PE tarpaulin, it is difficult to waterproof and the surface is slippery and workers may be injured.
이와 같은 문제점을 해결하기 위한 것으로서, 본 출원인에 의해 2001년 3월 19일 출원되어 2001년 6월 7일 등록된 국내 실용신안등록 제 234912호에는 천막의 표면에 미끄럼 방지 처리된 필름을 부착하고, 필요한 경우에는 미끄럼 방지필름의 표면에 다수의 엠보싱을 형성하여 표면 마찰력을 증대시킨 구성의 미끄럼 방지천막이 개시되어 있다. 즉, 이 미끄럼 방지천막은 PVC나 PE로 만들어진 천막본체와, 이 천막본체의 적어도 일면에 구비되는 것으로 표면에는 마찰 저항력이 증대되도록 미끄럼 방지처리된 미끄럼 방지층으로 이루어져 있다.In order to solve such a problem, domestic utility model registration No. 234912, filed on March 19, 2001 and registered on June 7, 2001 by the applicant, attaches a non-slip film to the surface of the tent, If necessary, a non-slip tent having a configuration in which a plurality of embossings are formed on a surface of an anti-slip film to increase surface frictional force is disclosed. That is, the anti-slip tent is made of PVC or PE tent body, and is provided on at least one surface of the tent body, the surface is composed of an anti-slip layer to prevent slipping so as to increase the frictional resistance.
이러한 구성에 의하면, 타포린 원단의 표면상에 미끄럼 방지 처리된 필름을 라미테이션으로 부착하거나 미끄럼 방지원료를 압출코팅하고 이 미끄럼 방지층의 표면에 다수의 엠보싱을 형성하여 표면 마찰력을 증대시킬 수는 있으나, 표면 마찰력의 증대에 한계가 있으므로, 눈이나 비가 많이 오는 기후 조건에서는 보다 강한 마찰력을 지닌 타포린이 요구된다.According to this configuration, it is possible to increase the surface friction force by attaching the anti-slip film on the surface of the tarpaulin fabric or by extrusion coating the anti-slip material and forming a plurality of embossing on the surface of the anti-slip layer. Since the increase in surface friction is limited, tarpaulins with stronger friction are required in snowy and rainy weather conditions.
한편, 종래의 PE 타포린은 양면을 동일한 재질(LDPE) 및 방법으로 도포하여 코팅하는 것으로서, 그 고유의 용도에 따라서 방수 및 통기성을 최대한 억제하는 것을 그 목적으로 하는 제품이다. 그런데, 동절기에 잔디구장이나 골프장의 그린 덮개용으로 사용할 경우에도 통기성 및 통수성이 낮아 겨울철 잔디보존에 좋지 않은 영향을 미친다.On the other hand, the conventional PE tarpaulin is coated by coating the both sides with the same material (LDPE) and method, it is a product whose purpose is to suppress the waterproofing and breathability as much as possible according to its unique use. However, even when used for the green cover of the grass field or golf course in winter, low breathability and water permeability adversely affects the conservation of grass in winter.
이러한 점을 보완하기 위한 것으로서, 본 출원인에 의해 2002년 1월 3일 출원된 국내 특허출원 제2002-197호에는 통기성 및 통수성과 미끄럼 방지를 위한 타포린이 있다. 이것은 폴리에틸렌을 직조하여 만든 직물층과, 저밀도폴리에틸렌(LDPE) 또는 에틸렌-초산비닐 수지를 주성분으로 하고, 보조성분으로서 하이드리조 디카본 아미드 또는 아조 디카본 아미드를 혼합하여 만든 수지 조성물이 상기 직물층의 일면 또는 양면에 코팅된 다공 코팅층을 포함하되, 적어도 일면의 상기 다공 코팅층에는 다수의 구멍이 형성되어 있는 것을 구성상의 특징으로 한다.As a supplement to this point, Korean Patent Application No. 2002-197, filed on January 3, 2002, by the present applicant, includes tarpaulins for breathability, water permeability, and slip prevention. This is a resin layer made by mixing a woven fabric layer made of polyethylene and a low density polyethylene (LDPE) or ethylene-vinyl acetate resin as a main component, and a hydride dicarbon amide or azo dicarbon amide as an auxiliary component. It includes a porous coating layer coated on one side or both sides, characterized in that a plurality of holes are formed in the porous coating layer of at least one side.
이러한 구성을 지닌 통기성 및 통수성과 미끄럼 방지를 위한 타포린의 경우에는, 타포린의 고유한 기능을 그대로 유지하면서도, 통기성과 통수성을 부여하여 동절기에 잔디구장의 덮개나 골프장의 그린 덮개용으로 사용이 가능하며, 방수성을 지니면서도 미끄럼 방지기능을 부여하여 다단으로 적재해야 하는 제품의 포장용이나 벌목장에서의 목재 보호용 덮개로서 사용할 수 있는 이점이 있다.In the case of tarpaulin for breathability, water permeability, and anti-slip having such a configuration, it can be used as a cover of a grass field or a green cover of a golf course in winter by providing breathability and water permeability while maintaining the unique function of tarpaulin. In addition, it has the advantage that it can be used as a protective cover for packing wood or timber in a product that must be loaded in multiple stages by providing a non-slip function while having waterproofness.
이것은 표면의 코팅층에 형성된 다수의 구멍에 의해서 우수한 통기성 및 통수성을 제공할 수는 있으나, 미끄럼 방지면에서는 마찰력이 다소 작은 단점이 있다.This can provide excellent air permeability and water permeability by a plurality of holes formed in the coating layer of the surface, but has a disadvantage that the friction force is rather small in the non-slip surface.
이와 같은 문제점을 해결하기 위한 본 발명은 타포린의 적어도 한쪽 표면을 보다 강력한 마찰력을 제공할 수 있는 구조로 코팅 처리하여, 미끄럼에 의한 각종 안전사고를 미연에 방지할 수 있는 미끄럼 방지용 타포린 및 그 제조방법을 제공하는데 그 목적이 있다.The present invention for solving the above problems is coated with at least one surface of the tarpaulin in a structure that can provide a stronger friction force, anti-slip tarpaulin and a method for manufacturing the same that can prevent various safety accidents due to sliding in advance The purpose is to provide.

상술한 목적을 달성하기 위한 본 발명의 미끄럼 방지용 타포린은 폴리에틸렌을 직조하여 만든 직물층과, 상기 직물층의 일면 또는 양면에 피복된 코팅층을 포함하되, 적어도 일면의 상기 코팅층에는 다수의 연사된 스플릿 얀이 일정한 간격을 두고 배열되어 있는 것을 특징으로 한다.The anti-slip tarpaulin of the present invention for achieving the above object includes a fabric layer made by weaving polyethylene and a coating layer coated on one or both sides of the fabric layer, wherein at least one side of the coating layer has a plurality of twisted yarns It is characterized by being arranged at regular intervals.
또한, 상술한 목적을 달성하기 위한 본 발명의 미끄럼 방지용 타포린의 제조방법은 폴리에틸렌을 직조하여 만든 직물층을 공급하는 단계와, 2가닥으로 꼬은 연사된 스플릿 얀을 일정 간격을 두고 배열되도록 상기 직물층 상에 공급하는 단계와, 직물층 상에 코팅제를 도포한 다음 냉각롤과 가압롤을 통과시켜 압출 코팅하는 단계를 포함하는 것을 특징으로 한다.In addition, the manufacturing method of the anti-slip tarpaulin of the present invention for achieving the above object is a step of supplying a fabric layer made of woven polyethylene, the fabric layer to be arranged at regular intervals twisted twisted yarns twisted into two strands It is characterized in that it comprises the step of supplying a phase, and applying the coating on the fabric layer and then extrusion coating by passing through a cooling roll and a pressure roll.
이하, 첨부한 도면을 참조하여 본 발명의 바람직한 실시예에 따른 미끄럼 방지용 타포린 및 그 제조방법에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a non-slip tarpaulin and a manufacturing method according to a preferred embodiment of the present invention.
천막용 타포린의 고유 기능인 야적물품의 보호성능을 그대로 유지하면서 표면 마찰력을 증대시키기 위한 방안으로 본 발명의 바람직한 실시예에서는 타포린의 일면에 도포되는 코팅층에 연사된 스플릿 얀을 삽입하여 함께 피복하는 방안을 예시하였다.In the preferred embodiment of the present invention, a method of coating the coated yarn with the split yarn inserted into the coating layer applied to one surface of the tarpaulin in order to increase the surface friction while maintaining the protection performance of the yard article, which is a unique function of the tarpaulin for the tent, is provided. Illustrated.
이때, 스플릿 얀은 가령, 고밀도 폴리에틸렌 수지를 여러 갈래의 가닥으로 쪼개어 연신하여 평탄한 테이프 형상의 얀으로 제조한 다음, 얻어진 평탄 테이프 얀에 세로로 다수의 칼집(split)을 내서 스플릿 얀을 제조한다. 다음에, 강도 증가를 위해서 스플릿 얀을 여러번 꼬아서 하나의 연사 형태로 만든다. 이때, 연사된 스플릿 얀은 한가닥을 사용하여도 되지만, 바람직하게는 두가닥을 꼬아서 사용하는 것이 강도와 마찰력 증대면에서 유리하다.At this time, the split yarn is, for example, divided into a plurality of strands of high-density polyethylene resin to prepare a flat tape-like yarn, and then a plurality of splits are vertically cut out to produce a split yarn. Next, the split yarn is twisted several times to form one continuous yarn for increased strength. In this case, the twisted split yarn may use one strand, but preferably two strands are twisted and advantageous in terms of strength and frictional increase.
이렇게 연사된 스플릿 얀은 통상의 방법으로 제조된 폴리에틸렌 직물 상에 일정한 간격을 두고 배열하여 코팅하게 된다.The split yarns thus twisted are arranged and coated at regular intervals on a polyethylene fabric produced by a conventional method.
여기에서, 상기 특허출원 제2002-197호에도 상세하게 개시된 바와 같이, 일반적인 PE 타포린의 제조과정을 보면, 타포린의 심재가 되는 고밀도 폴리에틸렌 직물을 직조한 후에, 이 직물을 언와인더(unwinder)에 인출 가능하게 설치한다. 다음에, 언와인더에서 인출된 직물은 제 1압출유닛과 제 2압출유닛의 가압롤로 이송한 후에, T-다이를 통해 코팅제를 공급하면서 직물의 양면을 압출 코팅하게 된다.Here, as disclosed in detail in Patent Application No. 2002-197, in the general manufacturing process of PE tarpaulin, after weaving a high-density polyethylene fabric that is the core of the tarpaulin, the fabric is placed on an unwinder Install it so that it can be pulled out. Next, the fabric taken out of the unwinder is transferred to the pressure rolls of the first extrusion unit and the second extrusion unit, and then extruded and coated on both sides of the fabric while supplying a coating agent through the T-die.
이 과정에서, 본 발명에서는 표면 마찰력의 증대를 위해서 도 1에 도시한 바와 같이 연사된 스플릿 얀을 공급하게 된다.In this process, the present invention is to supply the split yarn twisted as shown in Figure 1 to increase the surface friction force.
즉, 폴리에틸렌 직물을 공급함과 동시에(S10), 크릴 다이로부터 공급된 연사된 스플릿 얀을 폴리에틸렌 직물 위로 공급(S20)한 다음, T-다이를 통해 코팅제를 배출시키면서 코팅(S30)작업이 이루어져 본 발명의 미끄럼 방지 타포린(S40)을 완성하게 된다. 이 과정에서, 코팅을 마친 직물은 냉각공정(S35)을 거쳐 마찰열이 제거된 다음, 타측면의 코팅을 위해 이송된다.That is, at the same time supplying the polyethylene fabric (S10), and then fed (S20) the twisted split yarn supplied from the krill die onto the polyethylene fabric, the coating (S30) operation is made while discharging the coating through the T-die The anti-slip tarpaulin (S40) will be completed. In this process, the coated fabric is passed through the cooling process (S35) to remove the heat of friction, and then transferred for coating on the other side.
도 2에는 이러한 일련의 과정이 도시되어 있다. 크릴 스탠드(10)에는 다수(본 실시예에서는 4개)의 보빈축(12)이 소정의 각도로 고정되어 있으며, 이 보빈축(12)에 회전 가능하게 장착되어 있는 보빈(14)에는 2가닥으로 꼬은 연사된 스플릿 얀(16)이 인출 가능하게 권취되어 있다. 이때, 보빈(14)으로부터 풀려나오는 스플릿 얀(16)의 엉킴을 막기 위해서 적절한 장력을 유지하여야 하는데, 이를 위해서 가이드 롤러(20)와 크릴 스탠드(10)사이에는 텐션 롤러(18)를 배치하였다.2 shows this series of processes. A plurality of bobbin shafts 12 (4 in this embodiment) are fixed to the krill stand 10 at a predetermined angle, and two strands are provided on the bobbin 14 rotatably mounted to the bobbin shaft 12. The split yarn 16 twisted and twisted is wound up so that extraction is possible. At this time, in order to prevent tangling of the split yarn 16 released from the bobbin 14, an appropriate tension should be maintained. For this purpose, a tension roller 18 is disposed between the guide roller 20 and the krill stand 10.
가이드 롤러(20)를 따라 적절한 장력으로 인출되는 스플릿 얀(16)은 간격 조절판(22)을 거치면서 일정한 간격으로 정렬된다. 다음에, 언와인더로부터 공급된 폴리에틸렌 직물 상에 일정한 간격을 두고 길이방향으로 연장 배치되면서 T-다이로부터 인출되는 코팅제에 의해 소정의 압출코팅 작업이 진행된다.The split yarns 16 drawn out at an appropriate tension along the guide roller 20 are aligned at regular intervals while passing through the gap adjusting plate 22. Next, a predetermined extrusion coating operation is performed by the coating material drawn out from the T-die while being longitudinally disposed at regular intervals on the polyethylene fabric supplied from the unwinder.
이때, 바람직한 코팅제로서 저밀도 폴리에틸렌 혼합수지를 이용할 수 있다. 즉, 건식 혼합기 내에서 일정시간 동안 혼합되어 균일화된 저밀도 폴리에틸렌 혼합수지를 제 1압출유닛의 호퍼 내로 공급한 다음, 압출기에 의해 용융, 혼련한다. 다음에, T-다이(26)를 통과하면서 고온의 유동성 있는 필름 상태로 압출된 수지는 언와인더로부터 이송된 폴리에틸렌 직물의 일측면에 도포된 상태에서 제 1압출유닛의 냉각롤(24)과 가압롤 사이를 지나면서, 일정한 압력으로 가압 접촉되어 코팅이 완료된다.At this time, a low density polyethylene mixed resin can be used as a preferable coating agent. That is, the low-density polyethylene mixed resin which is mixed for a predetermined time in the dry mixer is fed into the hopper of the first extrusion unit, and then melted and kneaded by an extruder. Next, the resin extruded in the state of high temperature fluid film while passing through the T-die 26 is applied to one side of the polyethylene fabric conveyed from the unwinder and the cooling roll 24 of the first extrusion unit. Passing between the pressure rolls, the pressure is contacted at a constant pressure to complete the coating.
이 상태에서 제 2압출유닛으로 이송된 다음에, 동일한 방식으로 공급된 저밀도 폴리에틸렌 혼합수지가 직물의 타측면에 공급되어 압축 코팅됨으로써, 미끄럼 방지용 타포린이 완성되며, 완제품은 와인더에 롤형태로 권취된다.After being transferred to the second extrusion unit in this state, the low-density polyethylene mixed resin supplied in the same manner is supplied to the other side of the fabric and subjected to compression coating, whereby the anti-slip tarpaulin is completed and the finished product is wound in a roll in a winder. do.
도 3에는 이러한 과정을 거쳐 제조된 본 발명의 미끄럼 방지용 타포린의 평면사진이 도시되어 있다.3 is a plan view of the anti-slip tarpaulin of the present invention prepared through this process.
여기에 도시된 바와 같이, 폴리에틸렌 직물 상에는 다수의 연사된 스플릿 얀이 일정한 간격을 두고 배치되어 있으며, 이 스플릿 얀의 직경만큼 직물 상에는 다수의 돌출부가 제공됨으로써 표면 마찰력을 극대화시킬 수 있다. 이때, 연사 형태의 스플릿 얀은 약 2200데니어 정도가 바람직하며, 본 실시예에서는 2가닥을 꼬아서 만들기 때문에 44OO데니어의 굵기를 갖게 된다. 이와 같이, 천막의 길이방향을 따라서 일정한 간격을 두고 다수의 연사된 스플릿 얀이 함께 코팅되어 있으므로, 스플릿 얀의 직경만큼 높이가 높아짐으로써 매끈한 표면에 비해서 마찰력이 증대되는 결과를 가져온다.As shown here, a plurality of twisted split yarns are arranged at regular intervals on the polyethylene fabric, and a plurality of protrusions are provided on the fabric by the diameter of the split yarns to maximize the surface friction force. At this time, about 2200 denier is preferable for the twist yarn-shaped yarn, and in the present embodiment, since two strands are twisted, the yarn has a thickness of 44OO denier. As such, since a plurality of twisted split yarns are coated together at regular intervals along the longitudinal direction of the tent, the height of the split yarn is increased by the diameter of the split yarn, resulting in an increase in frictional force as compared to a smooth surface.
이상으로 설명한 본 발명에 의하면, 천막용으로 사용하는 타포린의 적어도 한쪽의 표면에, 2가닥의 스플릿 얀이 일정한 간격을 두고 길이방향을 따라 연장 배열되어 있어 다수의 돌출부를 제공하게 되며, 그로 인해 표면 마찰력이 증대되어 미끄럼에 의한 각종 안전 사고를 충분히 방지할 수 있는 이점이 있다.According to the present invention described above, on the surface of at least one of the tarpaulin used for the tent, two split yarns are arranged in the longitudinal direction at regular intervals to provide a plurality of protrusions, thereby the surface Increased friction has the advantage of being able to sufficiently prevent various safety accidents caused by sliding.
