Abstract

A method for coating PVC(polyvinyl chloride) on a polyester canvas fabric is provided to suppress the shrinkage of the fabric due to high-temperature drying, by drying the fabric within a chamber of a relatively low temperature, 70-180°C, while reciprocating the fabric. A thermal treatment process is performed by applying heat of 190-200°C to a polyester canvas fabric(2) horizontally moved while both sides of the fabric are pulled. A first PVC resin impregnation process is performed by immersing the fabric after the thermal treatment process in a first PVC resin bath(12) of a normal temperature while the fabric is moved by a roller(11). A first vertical reciprocation heat dry process is performed by drying the fabric after the first PVC resin impregnation process within a first drying chamber(14) of 170-180°C while the fabric is vertically reciprocated. A second PVC resin impregnation process is performed by immersing the fabric after the first vertical reciprocation heat dry process in a second PVC resin chamber(16) of 170-180°C. A second vertical reciprocation heat dry process is performed by drying the fabric after the second PVC resin impregnation process within a second drying chamber(18) of 170-180°C while the fabric is vertically reciprocated. A cooling process is performed by supplying cooling water to the fabric after the second vertical reciprocation heat dry process. In the thermal treatment process, the fabric is horizontally moved at a rate of 25-30 m/min in a thermal treatment chamber of 20-30 m. In all processes except the thermal treatment process, the fabric is moved at a rate of 3-4 m/min. The first drying chamber and the second drying chamber have lengths of 9-11 m.

본 발명은 폴리에스테르 캔바스 원단의 폴리염화비닐(PVC)코팅 방법을 제공한다. 본 발명은, 롤에 감겨진 폴리에스테르 캔바스 원단을 폴리염화비닐(PVC) 코팅하는 방법이다. 본 방법은 도시된 바와 같이 예비 처리 단계로서 열처리 공정(21)을 포함하며, 이 열처리된 원단에 PVC 코팅을 위한 단계들로서, 1차 PVC 수지 함침 공정(22)과, 1차 수직이동 열건조 공정(23)과, 2차 PVC 수지 함침 공정(24)과, 2차 수직이동 열건조 공정(25), 및 냉각공정(26)을 포함한다.The present invention provides a polyvinyl chloride (PVC) coating method of polyester canvas fabric. The present invention is a method of coating polyvinyl chloride (PVC) on a polyester canvas fabric wound on a roll. The method includes a heat treatment process 21 as a pretreatment step, as shown, as steps for PVC coating the heat treated fabric, a primary PVC resin impregnation process 22, and a first vertical transfer heat drying process. (23), a secondary PVC resin impregnation process (24), a secondary vertical transfer heat drying process (25), and a cooling process (26).

본 발명은 100% 폴리에스테르 섬유로 짜여진 직물 시트에 PVC를 코팅한 캔바스를 제조하기 위한 원단을 제조하는 방법에 관한 것이다.The present invention relates to a method of manufacturing a fabric for producing a canvas coated with PVC on a fabric sheet woven from 100% polyester fiber.

일반적으로 폴리에스테르 섬유는 원가 대비 인장력 등 경제성 및 물리적 특성이 우수하다. 또한 대형의 캔바스를 제조하기 위하여, 롤상에 감겨져 있는 원단을 소정 길이로 자르고, 잘라진 것의 가장자리를 예컨대 고주파 가열 방법에 의하 여 서로 이어 붙이는 경우, 폴리에스테르 섬유간 접착력이 좋으므로, 별도의 접착제가 필요없이 단순히 고주파 작업만으로 대형 치수의 캔바스 제품을 제조하기 편리하다는 등의 장점을 제공한다.In general, polyester fibers have excellent economic and physical properties, such as tensile strength, compared to the cost. In addition, in order to manufacture a large canvas, when the fabric wound on the roll is cut to a predetermined length and the edges of the cut pieces are connected to each other by, for example, a high frequency heating method, the adhesive strength between polyester fibers is good, so a separate adhesive is required. It offers the advantage that it is easy to manufacture large size canvas products simply by high frequency operation.

본 발명에 따라, 폴리에스테르 섬유로 짜여진 직물 시트(이하 '원단'이라 한다)는 예비처리로서 열수축을 위한 열처리 공정(21)을 거친다. 열처리 공정(21)은 상기 원단의 양측부를 잡아주면서 수평 이동시키면서 190 ~ 200℃의 열을 가하는 공정이다. 바람직한 실시예에 있어서, 상기 열처리 공정(21)은 25 ~ 30 m/분의 속도로 20 ~ 30 m 길이의 열처리 챔버에서 상기 원단을 수평 이동시키는 것으로 이루어질 수 있다. 이 공정은 원단이 미리 열수축과정을 받도록 하되 일정한 비율로만 수축되도록 처리하는 과정이다.According to the present invention, a fabric sheet woven from polyester fibers (hereinafter referred to as 'fabric') is subjected to a heat treatment process 21 for heat shrinkage as a pretreatment. Heat treatment step 21 is a step of applying a heat of 190 ~ 200 ℃ while moving horizontally while holding both sides of the fabric. In a preferred embodiment, the heat treatment process 21 may be made to horizontally move the fabric in a heat treatment chamber of 20 to 30 m length at a speed of 25 to 30 m / min. This process is to process the fabric to undergo a heat shrink process in advance, but shrink only at a constant rate.

이후 상기 열처리 공정(21)에서 열처리된 원단(2)은 PVC 코팅 공정으로 이송되며, 도 1에서 표시된 바와 같이 다수의 롤러(11)에 의해 한정되는 경로 상에서 이동된다. 열처리된 원단(2)은 1차 및 2차 PVC 수지 함침 공정(22, 24)과, 1차 및 수직이동 열건조 공정(23, 25)과, 냉각공정(26)을 따라 연속으로 처리됨으로써 PVC코팅된 원단(3)으로서 완성되고 권취되어 이후, 최종 캔바스 제품을 완성하기 위한 절단, 이어붙임, 포장 등의 후처리 공정으로 제공될 수 있다.Then, the fabric 2 heat-treated in the heat treatment process 21 is transferred to the PVC coating process, and is moved on a path defined by a plurality of rollers 11 as shown in FIG. The heat-treated fabric (2) is treated by successively following the primary and secondary PVC resin impregnation processes (22, 24), the primary and vertical transfer heat drying processes (23, 25), and the cooling process (26). Finished and wound as a coated fabric (3), it can then be provided in a post-treatment process such as cutting, pasting, packaging, etc. to complete the final canvas product.

1차 PVC 수지 함침 공정(22)은 이동시키면서 상온의 1차 PVC 수지조(12)에 함침시켜 PVC 수지가 상기 원단에 코팅되도록 하는 단계이다. 이 공정(22)에 의해 열처리된 원단(2)의 표면에 일정한 두께의 PVC 수지가 코팅될 수 있다. 코팅되는 두께는 원단의 이송 속도에 따라 결정될 수 있다. 본 발명의 바람직한 실시예에서, 상기 1차 PVC 수지 함침 공정(22) 내지 냉각공정(26) 내내 상기 원단은 약 4 야드/분의 속도, 바람직하게는 3 ~ 4m/분의 속도로 이송된다.The primary PVC resin impregnation process 22 is a step of impregnating the primary PVC resin tank 12 at room temperature while moving so that the PVC resin is coated on the fabric. PVC resin of a constant thickness may be coated on the surface of the fabric 2 heat-treated by this process (22). The thickness to be coated can be determined according to the conveying speed of the fabric. In a preferred embodiment of the invention, the fabric is conveyed at a rate of about 4 yards / minute, preferably 3-4 m / min, throughout the primary PVC resin impregnation process 22 to cooling process 26.

1차 코팅된 원단은, 1차 수직이동 열건조 공정(23)에 의하여 건조된다. 이 공정(23)은 도 2에 도시된 바와 같이, 대략 직육면체 형태의 건조챔버(14) 내에서 이루어지는데, 이 건조챔버의 길이는 약 10m 즉 약 9 ~ 11m 이고 폭은 원단의 폭에 따라 달라질 수 있는데, 원단의 일반적인 폭이 1m 내지 1.2m 인 경우 건조챔버의 폭은 약 1.8 m 정도인 것이 바람직할 것이다. 건조챔버의 두께는 원단이 한번 왕복이동하기에 충분한 크기이면 되며, 도시된 실시예의 경우 약 1m 정도일 수 있다.The primary coated fabric is dried by a primary vertically moving heat drying process (23). This process 23 is carried out in a drying chamber 14 in the form of a substantially cuboid, as shown in FIG. 2, the length of which is about 10 m or about 9 to 11 m and the width varies depending on the width of the fabric. If the general width of the fabric is 1m to 1.2m it may be preferred that the width of the drying chamber is about 1.8m. The drying chamber may have a thickness sufficient for the fabric to reciprocate once, and may be about 1 m in the illustrated embodiment.

1차 건조 공정(23)은 원단을 수직으로 왕복 이동되도록 하면서 열 건조시키는 과정이다. 즉 170 ~ 180℃의 온도를 유지하는 1차 건조챔버(14) 내에서 상기 1차 PVC 수지 코팅된 원단을 수직으로 왕복 이동시키면서 건조되도록 한다.The primary drying process 23 is a process of thermal drying while allowing the fabric to reciprocate vertically. That is, the primary PVC resin coated fabric is dried while reciprocating vertically in the primary drying chamber 14 maintaining the temperature of 170 ~ 180 ℃.

상기 1차 건조챔버(14)를 통과한 원단의 1차 코팅은 완전히 건조된다. 만약 건조챔버의 온도가 상기 온도보다 낮은 경우에는 건조가 불완전해질 수 있으므로, 이후 2차 코팅 및 2차 건조 공정이 불완전하게 이루어지게 되어 결국 제품 불량이 발생될 수 있다. 만약 건조챔버의 온도가 상기 온도보다 더 높은 경우에는 비록 예비 처리 단계인 열처리 공정(21)에서 더 높은 온도로 열처리된 원단이라 할지라도 열처리 공정보다 느린 속도로 이동하고 있는 원단에 지나치게 많은 열량이 공급될 수 있기 때문에 열수축 현상이 추가로 발생할 수 있다는 단점이 있다.The primary coating of the fabric passing through the primary drying chamber 14 is completely dried. If the temperature of the drying chamber is lower than the temperature, the drying may be incomplete, after which the secondary coating and the secondary drying process may be incomplete, resulting in product defects. If the temperature of the drying chamber is higher than the temperature, too much heat is supplied to the fabric moving at a slower speed than the heat treatment process, even if the fabric is heat treated at a higher temperature in the heat treatment process 21, which is a preliminary treatment step. There is a drawback that additional heat shrinkage may occur.

이렇게 1차로 코팅-건조과정이 완료된 원단은, 상기 1차 코팅-건조과정과 동일한 조건에서 2차 코팅-건조과정을 반복한다. 즉 2차 PVC 수지 함침 공정(24)에서 1차 건조된 원단을 상온의 2차 PVC 수지조(16)에 함침시켜 PVC 수지가 상기 원단에 코팅되도록 하며, 2차 수직이동 열건조 공정(25)에 의해, 170 ~ 180℃의 온도를 유지하는 2차 건조챔버(18) 내에서 상기 2차 PVC 수지 코팅된 원단을 수직으로 왕복 이동시키면서 건조되도록 한다.In this way, the first coating-drying process is completed, and the second coating-drying process is repeated under the same conditions as the first coating-drying process. That is, by impregnating the fabric firstly dried in the secondary PVC resin impregnation process (24) in the secondary PVC resin tank 16 at room temperature so that the PVC resin is coated on the fabric, the secondary vertical transfer heat drying process (25) By the above, the secondary PVC resin coated fabric in the secondary drying chamber 18 to maintain a temperature of 170 ~ 180 ℃ to dry while reciprocating vertically.
