차양막용 원단의 경우 고내광성을 요구하기 때문에 주로 아크릴이나 폴리에스테르등의 원착사를 이용하여 생산한 원단을 사용하고 있는데, 화재의 위험에 노출되어 있으므로 난연에 대한 소비자의 욕구가 점차 증대되는 추세이다.Since the shade fabric requires high light fastness, the fabric used is mainly made of acrylic or polyester. However, since it is exposed to the risk of fire, the consumer's desire for flame retardation is gradually increasing .
폴리에스테르 원착사의 경우 고내광성은 우수하지만 화재 발생시 난연성이 취약하므로 원단제직후 난연 또는 방염코팅을 하여 취약한 난연성을 보강하고 있다. Polyester base yarn is excellent in high light resistance but is weak in flame retardancy when a fire occurs, so that flame retardant or flame retardant coating is applied immediately after the fabric is finished to reinforce the weak flame retardancy.

Thereby providing a manufacturing method.
그러나 상기 선행기술에 대해 난연성 및 내광성 부여를 하기 위해서는 일반 난연 또는 방염 코팅을 하는 경우 황변현상이 발생하고, 내광성이 취약하고, 방수성이 다소 저하되는 현상이 발생되어 이러한 문제점을 극복하기 위한 새로운 방염코팅의 필요성이 제기되었다. However, in order to impart flame retardancy and light resistance to the prior art, a general flame-retardant or flame-retardant coating causes yellowing phenomenon, weak light resistance, and water resistance to be somewhat lowered.

상기 직물을 방염코팅액으로 코팅한 후 건조하는 방염코팅공정으로 이루어지는 것을 특징으로 하는 내광성이 우수한 차양막용 폴리에스테르난연원단의 제조방법이 제공된다.And a flame-retardant coating step of coating the fabric with a flame-retarding coating liquid and then drying the flame-retarding coating liquid.
이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명의 내광성이 우수한 차양막용 폴리에스테르난연원단의 제조방법은 난연성 폴리에스테르원착필라멘트를 원사로 하여 ATY사를 만들고 연사한 후 제직하여 방염코팅을 하는 것이다.The method for producing a polyester flame retardant fabric for a shining film excellent in light fastness of the present invention is to produce an ATY yarn by using a flame retardant polyester original filament as a yarn, and then spinning the yarn after weaving the yarn.
원사는 난연성 폴리에스테르원착필라멘트를 사용하는데, 공지의 난연성 폴리에스테르원착필라멘트를 원사로 사용하여도 좋다. 특히, 인계난연제, UV안정제 및 안료를 함유한 폴리에스테르칩으로 방사한 폴리에스테르원착필라멘트인 것을 사용하는 것이 내광성발현에 좋다. 상기 난연성 폴리에스테르원착필라멘트에 함유된 인계난연제는 0.2~0.5중량%함유되는 것이 좋고, UV안정제는 3~5중량% 함유되는 것이 좋다.The yarn is a flame retardant polyester origin filament, and a known flame retardant polyester origin filament may be used as the yarn. Particularly, it is preferable to use a polyester-derived filament spun in a polyester chip containing a phosphorus flame retardant, a UV stabilizer and a pigment, which is good for light resistance. The phosphorus-based flame retardant contained in the flame-retardant polyester-derived filament may be contained in an amount of 0.2 to 0.5% by weight, and the UV stabilizer may be contained in an amount of 3 to 5% by weight.
상기 난연성 폴리에스테르원착필라멘트는 원단제조시 면사와 같은 TOUCH와 벌키성을 지닌 천연색조의 외관(LOOKING)과 감촉을 부여하기 위해 ATY공정을 하는데, 심사로 난연성 폴리에스테르원착필라멘트를 피드롤러에 의해 오버피드율 5~15%로 공급하고, 효과사로 난연성 폴리에스테르원착필라멘트를 오버피드율 10~20%로 공급한 후, 에어텍스쳐노즐에서 공기압 5~10㎏/㎠으로 에어텍스쳐를 한 후 사속 30 ∼ 60m/분으로 권취하여 ATY사로 만들게 된다.The flame retardant polyester original filament is subjected to an ATY process in order to give a TOUCH like the cotton yarn and a natural hue having a bulky character and feel during the production of the fabric. The flame-retardant polyester original filament is peeled off by the feed roller Feed rate is 5 to 15%, an effective flame-retardant polyester-based filament is fed at an overfeed rate of 10 to 20%, air-textured at an air pressure of 5 to 10 kg / And wound up at 60 m / min to make ATY yarn.
심사의 오버피드율 5%미만에서는 교락이 잘 되지 못하는 문제점이 발생할 수 있고, 15%초과시에는 원사의 물성이 저하되는 문제점이 있으며, 효과사의 오버피드율 10%미만에서는 cotton-like한 효과가 잘 발현되지 못하는 문제점이 발생할 수 있고, 20%초과시에는 작업성이 좋지 못한 문제점이 발생할 수 있다.If the overfeed rate is less than 5%, the problem of collapse can not be achieved. If the overfeed rate is more than 15%, the properties of the yarn are deteriorated. If the overfeed rate is less than 10%, the cotton- It can not be expressed. If it exceeds 20%, the workability may be poor.
이후 상기 폴리에스테르ATY사를 T/M 200~400으로 연사하여 경,위사로 공급하여 제직하는 제직공정을 행하는데, 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 처짐현상의 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.Thereafter, the polyester ATY yarn is twisted at a T / M ratio of 200 to 400 to be weighed by weaving and weaving. The sizing process may be omitted if the twist yarn is used for light yarn. Even if the sizing process is carried out, it is possible to improve the quality of the fabric by improving the quality of the fabric and improving the appearance of the fabric. . 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.
본 발명의 내광성이 우수한 폴리에스테르난연원단의 제조방법에서는 시레공정을 하지 않고 직물을 방염코팅액으로 코팅한 후 건조하는 방염코팅공정을 행하는 것이 특징이다.In the method for producing a polyester flame retardant fabric having excellent light resistance of the present invention, a flame-retardant coating process is performed in which a fabric is coated with a flame-retarding coating solution and then dried.
일반적으로 시레공정을 통해 원단바닥면을 균일하게 하여 균일한 코팅이 되도록 하여 내수압을 향상시켜 후에 있을 코팅공정후 원단의 표리간 색상차가 심하게 발생하는 현상을 방지하고 있으나 본 발명에서는 방염코팅액의 조성을 하기와 같은 조성으로 함으로써 시레공정을 하지 않아도 균일한 코팅을 할 수 있도록 하고 있다.In general, the bottom surface of the fabric is uniformized through a syringe process so as to provide a uniform coating, thereby improving the water pressure so as to prevent a significant difference in color between the front and back of the fabric after the coating process. However, So that uniform coating can be performed even without a sieving process.
상기 방염코팅공정은 연질폴리우레탄수지와 무황변폴리우레탄수지의 혼합수지 30~40중량%, 경질폴리우레탄수지 20~50중량%, 방염제로서 Oligomeric Phosphate Ester 5~15중량%, 경화제 5~10중량%, 톨루엔 10~15중량%로 이루어진 방염코팅액으로 직물을 코팅함으로써 시레가공을 하지 않고도 방수성 향상과 원단 이면의 균일성을 유지할 수 있으며, 일반 난연 또는 방염 코팅의 경우 발생하는 황변현상과 방수도 저하를 방지한다. The flame-retardant coating process is carried out by mixing 30 to 40% by weight of a mixed resin of a flexible polyurethane resin and a non-yellowing polyurethane resin, 20 to 50% by weight of a hard polyurethane resin, 5 to 15% by weight of an oligomeric phosphate ester as a flame retardant, %, And toluene 10 ~ 15 wt%. Thus, it is possible to improve the waterproof property and uniformity of the back surface of the fabric without sieving processing, and the yellowing phenomenon and waterproofing .
상기 연질폴리우레탄수지는 점도 1400~1600 poise/20℃, 탄성계수 100%MD 10~30㎏/㎠인 것을 사용하고, 무황변폴리우레탄수지는 탄성계수 100%MD 20~30㎏/㎠)를 사용하는 것이 원단의 방수성 및 황변성을 방지하는데 효과적이고, 상기 연질폴리우레탄수지와 무황변폴리우레탄수지는 중량비 30:70~50:50으로 혼합하여 혼합수지로 사용하는 것이 좋다. 경질폴리우레탄수지는 점도 1400 - 1600 poise/20℃, 탄성계수 100%MD 80~90㎏/㎠인 것을 사용하는 것이 바람직하다.The flexible polyurethane resin having a viscosity of 1400 to 1600 poise / 20 캜 and an elastic modulus of 100%
연질폴리우레탄수지와 무황변폴리우레탄수지의 혼합수지는 30~40중량%가 함유되고, 경질폴리우레탄수지는 20~50중량%가 함유되는 것이 원단이면의 균일성을 향상시키는데 좋다. 방염제는 Oligomeric Phosphate Ester가 5~15중량%가 함유되는 것이 황변현상방지 및 일광견뢰도 향상에 바람직하다.The mixed resin of the flexible polyurethane resin and the non-yellowing polyurethane resin is contained in an amount of 30 to 40% by weight, and the hard polyurethane resin is contained in an amount of 20 to 50% by weight in order to improve the uniformity of the back surface. The flame retardant preferably contains 5 to 15% by weight of an oligomeric phosphate ester to prevent yellowing and improve light fastness to light.
상기 방염코팅공정 후 건조 온도 160~170℃, 건조 속도 10~30mpm으로 원적외선건조기에서 건조하여 본 발명의 내광성이 우수한 차양막용 폴리에스테르난연원단을 제조하게 된다.After the flame-retardant coating process, the polyester film is dried in a far-infrared ray dryer at a drying temperature of 160 to 170 ° C and a drying rate of 10 to 30 mpm to produce a polyester flame retardant fabric for a shining film excellent in light fastness.
따라서 본 발명에 의하면 시레가공을 하지 않고도 방수성 향상과 원단 이면의 균일성을 유지할 수 있으며, 일반 난연 또는 방염 코팅의 경우 발생하는 황변현상과 방수도 저하를 방지하고 방염효과(LOI 30이상) 및 방수효과(1000이상)와 고내광성을 발현하는 차양막용으로 적합한 원단을 제공할 수 있다.Therefore, according to the present invention, it is possible to improve the waterproof property and uniformity of the back surface of the fabric without sieving, and to prevent deterioration of the yellowing phenomenon and the waterproofing in the case of ordinary flame retardant or flame retardant coating, It is possible to provide a fabric suitable for an effect (1000 or more) and a shining film exhibiting high light resistance.
