본 발명은 차양막용 원착폴리프로필렌 직물의 제조방법에 관한 것으로서 안료입자크기가 0.1∼3㎛정도로 미세하고 균제도가 우수한 폴리프로필렌 원착사를 복합하여 원단을 제조하는 방법에 관한 것이다. The present invention relates to a method for producing an original polypropylene fabric for a shading film, and more particularly, to a method for producing a fabric by blending polypropylene raw materials having a fine particle size of about 0.1 to 3 탆 and excellent uniformity.
국내 차양막 원단의 경우 주로 폴리프로필렌 원형 원착사를 이용하여 생산하고 있고 대부분 솔리드(SOLID) 또는 경,위사 방향에 배열을 넣어 만든 원단이 주종을 이루고 있는데, 수요자들은 이러한 원단에 문양을 넣어 새로운 조직의 변화로 제품의 단조로움에서 탈피하여 고품질의 차별화된 차양막용 문양 원단을 요구하고 있다.Domestic shade fabrics are mainly produced using polypropylene round yarns, and most of them are made of solid (SOLID) or a fabric made by arranging in the direction of light and weft. And it is demanding the high quality differentiated pattern for the shading film.
기존에 생산되고 있는 폴리에스터 차양막 원단의 경우 원단 비중이 1.38로 폴리프로필렌)0.91)보다 높아 원단 제품이 무겁고 원단 소요량 증가로 인한 제조원가 상승으로 제품의 가격경쟁력이 저하되고 제품의 오염도가 높은데 반하여, 폴리프로필렌의 경우 수분흡수율이 제로에 가까워 제품의 오염도가 저하되고 유럽 등에서는 친환경 소재로도 주목을 받고 있다. 그러나 기존의 차양막 원단용으로 사용하는 폴리프로필렌 원착사의 경우 M/chip의 안료 입자크기가 5㎛보다 커서 균질성이 떨어지고 색상이 어둡고 둔탁하며, 일광견뢰도 저하에 따른 색상이 탈색되고, 오염도 증가, 내수압 저하, 코팅면의 sticky현상과 chalk mark 발생 등의 문제점을 가지고 있었다.In the case of the conventional polyester shade fabric, the specific gravity of the fabric is 1.38, which is higher than that of polypropylene (0.91). As a result, the price of the product is low and the contamination degree of the product is high due to the heavy fabric product, In the case of propylene, the water absorption rate is close to zero, so that the degree of contamination of the product is lowered, and in Europe, it is attracting attention as an eco-friendly material. But In the case of the polypropylene bonded yarn used for the conventional shingled fabric, the pigment particle size of M / chip is larger than 5 μm, the homogeneity is lowered, the color is dark and dull, the color is discolored due to the decrease in the fastness of daylight, Sticky phenomenon of coating surface and chalk mark generation.
그러므로 본 발명에서는 기존의 문제점을 보완하기 위해 원단의 색상 선명도 향상은 물론, 내광성이 우수해 일광견뢰도가 향상되고, 오염도 저하, 내수압 향상 및 코팅면의 sticky현상과 chalk mark 발생을 방지하고 균제도가 뛰어난 친환경적인 차양막용 원단을 제공하는 것을 기술적과제로 한다.Therefore, in order to solve the problems of the prior art, the present invention has been made to improve the color sharpness of the fabric as well as to improve the color fastness of the fabric, to improve the fastness of daylight, to decrease the pollution degree, to increase the water pressure, to prevent sticky phenomenon and chalk mark on the coated surface, It is a technical object to provide an environmentally friendly shading fabric.
그러므로 본 발명에 의하면, 폴리프로필렌원착필라멘트를 코어사와 이펙트사로 공급하여 에어텍스쳐링한 에어텍스쳐사를 T/M 100∼300으로 연사하여 경,위사로 공급하여 직물을 제직한 후, Therefore, according to the present invention, air-textured yarn air-textured by supplying a polypropylene original filament to a core yarn and an effect yarn is twisted at a T / M of 100 to 300,
정련 및 발수가공을 한 후, 직물의 표면 또는 이면을 60~80℃로 시레작업을 한 후, After scouring and water-repellent processing, the surface or back of the fabric is sieved to 60 to 80 ° C,
연질 폴리우레탄수지와 경질 폴리우레탄수지를 중량비 35:65~45:55로 혼합한 혼합폴리우레탄 수지 75∼90중량%, 경화제 1∼5중량%, 소광제 1∼5중량%, 잔부로서 톨루엔을 함유한 코팅액으로 상기 직물을 코팅한 후, 건조하는 것을 특징으로 하는 폴리프로필렌 이형단면 원착사를 이용한 내광성이 우수한 차양막용 직물의 제조방법이 제공된다. 75 to 90% by weight of a mixed polyurethane resin obtained by mixing a flexible polyurethane resin and a hard polyurethane resin in a weight ratio of 35:65 to 45:55, 1 to 5% by weight of a curing agent, 1 to 5% by weight of a quencher, The present invention also provides a process for producing a fabric for an ornamental shade having excellent light fastness using the polypropylene cross section cross-linked yarn characterized in that the fabric is coated with a coating solution containing the polypropylene cross-section.
이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명의 차양막용 원착폴리프로필렌 직물은 폴리프로필렌 이형단면 원착필라멘트의 에어텍스쳐사를 연사하여 경,위사로 공급하여 직물을 제직한 후, 정련 및 발수가공을 한 후, 시레작업을 한 후, 혼합폴리우레탄 수지, 경화제, 톨루엔을 함유한 코팅액으로 코팅한 후, 건조하여 제조하게 된다.The present polypropylene fabric for a shading film of the present invention is characterized in that an air texture yarn of polypropylene cross-section seamless filament yarn is twisted and fed into a yarn and a weft yarn to weave the fabric, followed by refining and water repellent processing, A polyurethane resin, a hardener, and a coating liquid containing toluene, followed by drying.
원사는 폴리프로필렌원착필라멘트를 사용하는데, 특히 입경 0.1~3um인 원착안료입자를 함유하고 원사단면이 원형단면, 삼각단면, 오각단면, 육각단면, 팔각단면 중 어느 하나인 폴리프로필렌필라멘트를 사용하는 것이 원단표면의 매끄러움과 균제도가 뛰어나고 광택성이 우수한 차양막용 원단을 제공할 수 있다. 상기 폴리프로필렌원착필라멘트는 방사시 원착안료입자가 균일하게 분산되도록 하여 방사구금이 막히지 않도록 하여야 하며, 필라멘트내에 균일하게 원착안료입자가 분산되어 강도의 저하나 색상의 불균일이 발생하지 않도록 최적의 방사조건으로 방사해야 한다.The yarn uses a polypropylene filament, and particularly uses a polypropylene filament having a circular particle cross-section, a triangular cross section, a hexagonal cross section, an octagonal cross section, and an octagonal cross section with a raw material particle having a particle diameter of 0.1 to 3 urn It is possible to provide a fabric for an orifice film excellent in smoothness and uniformity of the fabric surface and excellent in gloss. The polypropylene-based filament is required to uniformly disperse the raw material particles during the spinning so that the spinneret is not clogged. In order to uniformly disperse the raw material particles in the filament, It should be radiated under irradiation conditions.
상기 폴리프로필렌원착필라멘트는 코어사와 이펙트사로 공급하여 에어텍스쳐링한 에어텍스쳐사를 만들어 사용하게 되는데, 원단제조시 면사와 같은 TOUCH와 벌키성을 지닌 천연색조의 외관(LOOKING)과 감촉을 부여함으로서 고감성의 원단을 제조할 수 있다.The polypropylene original filament is supplied to the core yarn and the effect yarn to produce an air-textured yarn that is air-textured. In the production of the fabric, the appearance and comfort of a natural hue having a TOUCH and a bal- Can be fabricated.
상기 에어텍스쳐사는 코어사용 공급롤러로 코어사를 오버피드율 5∼35%로 공급하고, 이펙트사용 공급롤러로 이펙트사를 오버피드율 10∼40%로 공급한 후 에어압력 5∼25kg/㎠으로 에어텍스쳐링 하는 것이 바람직한데, 코어사의 오버피드율 5%미만에서는 교락이 잘 되지못하는 문제점이 발생할 수 있고, 35%초과시에는 코어사가 사표면으로 돌출하여 균제도가 저하되는 문제점이 있으며, 이펙트사의 오버피드율 10%미만에서는 모우효과가 잘 발현되지 못한 문제점이 발생할 수 있고, 40%초과시에는 작업성이 좋지 못한 문제점이 발생할 수 있다. The air texture yarn is fed to the core use feed roller at an overfeeding rate of 5 to 35%, and the effect yarn is fed to the effect using feed roller at an overfeeding rate of 10 to 40%, followed by an air pressure of 5 to 25 kg / However, when the overfeed rate of the core yarn is less than 5%, the core yarn may not be satisfactorily intertwined. When the core yarn exceeds 35%, the core yarn is projected to the surface of the core yarn and the uniformity of the core yarn is lowered. If the ratio is less than 10%, a problem of insufficient mowing may occur. If the ratio exceeds 40%, the workability may be poor.
상기 에어텍스쳐사는 T/M 100~300으로 연사하여 경,위사로 공급하여 직물을 제직하게 되는데, 상기 연사된 사를 경사용으로 사용하면 사이징(SIZING)공정이 생략될 수 있고, 사이징공정을 거치더라도 호제를 적게 묻혀도 제직성이 양호하고 정련이 용이하여 원단의 외관상 품질을 높일 수 있고 원단의 탄성을 높혀 원단의 처짐현상 개선과 세척성 향상으로 원단 표면의 오염도를 개선할 수 있다. 위사용으로 연사된 사를 제공하면 원단 상태에서 경사방향 대비 위사방향으로의 인열강도가 상대적으로 낮은 편이라서 원단의 형태안정성면에서 문제점을 지니고 있는데 상기 연사된 사의 T/M 조건을 상기와 같이 조절함으로써 위사방향으로의 인열강도를 보강함으로서 이러한 문제점을 개선할 수 있는 장점이 있다.The air texture yarn is twisted at a T / M ratio of 100 to 300, and is supplied to the yarn and weft yarns to weave the fabric. If the twist yarn is used for light yarn, the sizing process may be omitted, Even if a little foaming agent is buried, it is possible to improve the appearance quality of the fabric by improving the smoothness and refinement of the fabric, and by improving the elasticity of the fabric, it is possible to improve the deflection phenomenon of the fabric and improve the cleanability. Since the tear strength in the warp direction is relatively low in the warp direction, the warp yarn has a problem in terms of the shape stability of the fabric. However, Thereby improving the tear strength in the weft direction, thereby improving the problem.
제직후, 정련 및 발수가공을 한 후, 직물의 표면 또는 이면을 60~80℃로 시레작업을 하여 원단바닥면을 균일하게 하여 균일한 코팅이 되도록 하여 내수압을 향상시켜 후에 있을 코팅공정후 원단의 표리간 색상차가 심하게 발생하는 현상을 방지할 수 있다. The surface or back of the fabric is subjected to a shirring operation at a temperature of 60 to 80 ° C. to uniform the bottom surface of the fabric so as to provide a uniform coating so as to improve the water pressure, It is possible to prevent a phenomenon that the color difference between the front and the back is seriously generated.
상기 시레공정 후에는 연질 폴리우레탄수지와 경질 폴리우레탄수지를 중량비 35:65~45:55로 혼합한 혼합폴리우레탄 수지 75∼90중량%, 경화제 1∼5중량%, 소광제 1∼5중량%, 잔부로서 톨루엔을 함유한 코팅액으로 상기 직물을 코팅한 후, 건조하여 본 발명의 차양막용 원착폴리프로필렌 직물을 완성하게 된다.After the above-mentioned sieving process, a mixed polyurethane resin in which the soft polyurethane resin and the hard polyurethane resin are mixed in a weight ratio of 35:65 to 45:55 is mixed with 75 to 90% by weight, the curing agent is 1 to 5% by weight, , And the remainder is coated with the coating liquid containing toluene, followed by drying, thereby completing the original polypropylene fabric for an evening shade film of the present invention.
상기 연질 폴리우레탄수지는 밀도 15~30㎏/㎥이고, 경질 폴리우레탄수지는 밀도 35~60㎏/㎥인 것을 사용하는 것이 바람직하다. 상기 혼합폴리우레탄 수지는 연질 폴리우레탄수지와 경질 폴리우레탄수지를 중량비 35:65~45:55로 혼합한 것을 사용하는 것이 바람직한데, 연질 폴리우레탄수지가 중량비 35미만인 경우에는 코팅 후 원단에 chalk mark 현상이 발생할 수 있으며, 연질 폴리우레탄수지가 중량비 45초과인 경우에는 코팅면의 sticky현상이 발생할 수 있다. 소광제 1중량%미만에서는 코팅면이 번들거리는 현상이 발생되는 문제점이 발생하며, 5중량%를 초과하는 경우에는 원단 코팅면의 불균일한 문제가 발생할 수 있다. The flexible polyurethane resin preferably has a density of 15 to 30 kg / m 3 and the hard polyurethane resin has a density of 35 to 60 kg / m 3. The mixed polyurethane resin is preferably a mixture of a soft polyurethane resin and a hard polyurethane resin in a weight ratio of 35:65 to 45:55. When the soft polyurethane resin is less than 35 by weight, a chalk mark And when the weight ratio of the soft polyurethane resin is more than 45, the sticky phenomenon of the coated surface may occur. If the amount of the quenching agent is less than 1 wt%, the coated surface may become unstable. If the amount of the quenching agent is more than 5 wt%, unevenness of the coated surface may occur.
상기 혼합폴리우레탄 수지 75∼90중량%, 경화제 1∼5중량%, 소광제 1∼5중량%, 잔부로서 톨루엔을 함유한 코팅액은 차양막의 내수압 증가로 우기시 비가 새는 것을 막아주고 차양막 원단 설치 후 반발력 향상으로 원단의 처짐 현상을 향상시키는 작용을 하며, 일광견뢰도 4.5급 이상(200hrs, 80±3%), 내수압(1,350㎜H2O)의 물성을 가져 방수효과(1000이상)와 고내광성이 우수함을 알 수 있다.The coating liquid containing 75 to 90% by weight of the mixed polyurethane resin, 1 to 5% by weight of a curing agent and 1 to 5% by weight of a quencher as a remainder and toluene as a remainder is used to prevent rain from leaking due to an increase in water pressure in the orifice, It improves the deflection phenomenon of the fabric due to the improvement of the repulsive force. It has a water fastness of more than 4.5 grade (200hrs, 80 ± 3%) and water pressure (1,350㎜H 2 O) It can be seen that it is excellent.
그러므로 본 발명에 의하면, 폴리프로필렌 원착사를 복합하여 새로운 문양의 조직감을 직물에 부여함으로서 원단의 색상 선명도 향상은 물론, 내광성이 우수해 일광견뢰도가 향상되고, 오염도 저하, 내수압 향상 및 코팅면의 sticky현상과 chalk mark 발생을 방지하고 균제도가 뛰어난 친환경적인 차양막용 원단을 제공할 수 있다.Therefore, according to the present invention, it is possible to improve the color clarity of a fabric by imparting a texture of a new pattern to a fabric by incorporating a polypropylene raw yarn, thereby improving light fastness and light fastness, It is possible to provide an environmentally friendly fabric for an ornamental shade which prevents development and chalk mark occurrence and has excellent uniformity.
