본 발명은 편성물을 기재로 사용하고 촉감이 향상된 인공피혁의 제조방법에 관한 것이다.The present invention relates to a method for producing an artificial leather using a knitted fabric as a base material and improved tactility.
인공피혁은 극세섬유가 3차원적으로 교락되어 형성된 부직포에 고분자 탄성체가 함침되고 표면에 기모를 형성하여 이루어진 것으로, 천연피혁과 유사하게 부드러운 질감 및 독특한 외관을 가져, 신발, 의류, 장갑, 잡화, 가구 및 자동차 내장재 등과 같은 다양한 분야에 널리 이용되고 있다.The artificial leather is made of a nonwoven fabric formed by three-dimensionally entangled microfine fibers, impregnated with a polymer elastomer and brushed on the surface, and has a soft texture and a unique appearance similar to natural leather, and is used for shoes, clothes, gloves, Furniture and automobile interior materials, and the like.
그런데 부직포 기재의 인공피혁은 기재의 가격이 비싸고 제조가 까다로워 제조원가가 상승하며, 부위간 밀도 차이가 발생하여 불균일해지고, 의류용으로 사용하기에 두껍고, 유연성과 신축성이 부족하며, 색의 이염이 발생하는 문제점이 있다. However, the artificial leather of the nonwoven fabric is expensive because of the high cost of the base material, the manufacturing cost is increased, the manufacturing cost is increased, the density difference between the parts is generated and becomes nonuniform, thick for use in clothes, lack flexibility and stretchability, .
이를 해결하기 위해 편성물 기재의 인공피혁이 개발되고 있다. To solve this problem, artificial leather based knitted fabrics are being developed.
대한민국 등록특허 제0813459호의 환편조직의 스웨이드조 인공피혁의 제조방법에 의하면, 용출성분과 섬유형성성분으로 구성되며 용출 후 단사섬도가 0.03∼0.3데니어인 폴리에스터계 해도사 또는 분할사에 20∼30%의 비수 수축율을 가지는 단사섬도 1∼3 데니어의 고수축 폴리에스터 필라멘트를 인터레이스하여 환편하고, 염색을 하고, 건조한 후, 폴리우레탄을 부여하고, 수세 및 탈 DMF, 버핑, 감량, 건조 및 텀블러 공정을 하는 것을 특징으로 하는, 환편조직의 스웨드조 인공피혁의 제조방법이 기재되어 있다. According to the method for producing suede artificial leather of the circular knitting structure of Korean Patent Registration No. 0813459, it is possible to produce a suede artificial leather of 20 to 30 parts by weight, which is composed of an eluting component and a fiber forming component and has a single yarn fineness of 0.03 to 0.3 denier, % Shrinkage ratio, 1 to 3 denier, high shrinkage polyester filaments are interlaced, loosened, dyed, dried, and then subjected to polyurethane treatment, followed by washing with water and de-DMF, buffing, weight loss, drying and tumbling A method for manufacturing a suede artificial leather of a circular knit structure is disclosed.
그런데 인공피혁은 다양한 분야에 사용되므로 외관 품질과 함께 유연성, 탄성, 부드러운 촉감 등과 같은 감성품질도 우수하여야 하며, 신축성 등 기계적 물성 면에서 우수하여야 하여야 한다.However, since artificial leather is used in various fields, it must have excellent sensibility qualities such as flexibility, elasticity and soft touch as well as appearance quality, and should be excellent in mechanical properties such as stretchability.
이에 따라 편성물 기재의 인공피혁에서도 인공피혁이 요구하는 다양한 특성을 향상시키기위한 개발이 필요하다. Accordingly, it is necessary to develop artificial leather of knitted fabrics in order to improve various characteristics required of artificial leather.
본 발명은 상기와 같은 요구에 대응하기 위해, 편성물 기재의 인공피혁에서 편성물을 개량하여 촉감을 향상하는 것을 목적으로 한다.In order to meet the above-mentioned demand, the present invention aims to improve the knitted fabric of artificial leather of knitted fabric base material to improve touch.
상기 과제를 해결하기 위해 본 발명은, 폴리에스테르 해도사 또는 분할사, 및 폴리에스테르계 필라멘트를 합사하여 원사를 제조하는 단계; 상기 원사로 환편 또는 경편 조직의 편성물을 제조하는 단계; 상기 편성물을 유기 용매로 처리하여 고밀도의 수축포를 얻는 수축 단계; 상기 수축포를 수산화나트륨 수용액으로 감량 처리하여 섬유 극세화 편성물을 얻는 감량 단계; 상기 섬유 극세화 편성물에 폴리우레탄을 함침시켜 함침포를 얻는 함침 단계; 상기 함침포의 표면에서 연삭을 하여 기모가 형성된 함침포를 얻는 기모 단계; 및 상기 기모가 형성된 함침포를 염색하는 염색 단계;를 포함한 인공피혁의 제조방법을 제공한다. In order to solve the above-described problems, the present invention provides a method for producing a yarn, comprising the steps of: preparing a yarn by laminating a polyester chart yarn or a split yarn and a polyester- Preparing a knitted fabric of a circular or warp knitted fabric from the yarn; A shrinking step of treating the knitted fabric with an organic solvent to obtain a high-density shrink wrap; A weight reduction step of reducing the water-containing resin by an aqueous solution of sodium hydroxide to obtain a fiber microfine knitted fabric; Impregnating the fiber microfine knitted fabric with polyurethane to obtain an impregnation; A grinding step of grinding the surface of the impregnation so as to obtain an impregnation formed with brushed; And a dyeing step of dyeing the bristle with the bristles formed thereon.
본 발명에 의하면 폴리에스테르 극세사 및 통상의 폴리에스테르사의 합사로 이루어진 편성물을 유기 용매로 수축시킴으로써, 폴리에스테르 원사의 열 이력에 상관없이 편성물이 우수한 수축성을 나타낸다. 이로 인해 편성물 조직의 밀도 향상으로 비침이 억제되어 최종적으로 인공피혁에서 외관품질과 촉감이 향상된다. According to the present invention, a knitted fabric made of a polyester microfiber and a conventional polyester yarn is shrunk with an organic solvent, whereby the knitted fabric exhibits excellent shrinkability irrespective of the thermal history of the polyester yarn. As a result, the nonwoven fabric is suppressed by the improvement of the density of the knitted fabric, so that the appearance quality and feel of the artificial leather are improved finally.
본 발명은, 용출 성분과 섬유형성성 성분으로 구성된 폴리에스테르 해도사 또는 폴리에스테르 분할사, 및 폴리에스테르계 필라멘트를 합사하여 원사를 제조하고, 상기 원사로 환편 또는 경편 조직의 편성물을 제조하여 수축시킨 후, 상기 편성물에 탄성체를 함침시키고 연삭하여 이루어지는, 외관 품질이 향상된 인공피혁에 관한 것이다. The present invention relates to a process for producing a yarn by laminating a polyester chart or a polyester split yarn composed of an eluted component and a fiber-forming component and a polyester filament, and knitting a circular or warp knitted fabric with the yarn, And then the knitted fabric is impregnated and ground with an elastic body to improve the appearance quality.
상기 원사는, 극세화가 가능한 해도사 또는 분할사에 단사섬도 1~5 데니어의 폴리에스테르계 필라멘트를 상호 인터레이스한, 인터레이스사를 사용할 수 있다. The yarn may be an interlaced yarn in which polyester filaments having a single yarn size of 1 to 5 denier are interlaced with sea-bed or split yarn which can be made finer.
상기 극세화에 의한 극세사의 제조형태는 일반적으로 해도형(海島形), 분할형, 직접방사형 등이 있으나, 본 발명에서는 최종적으로 단사 섬도가 0.1~1.0 데니어를 가져 천연 스웨이드 느낌과 부드러운 촉감을 나타내기에 충분한 극세사를 사용할 수 있다. In the present invention, the monofilament fineness is 0.1 to 1.0 denier in the present invention, and a natural suede feeling and a soft touch are exhibited. Microfiber yarn enough to be used can be used.
상기 폴리에스테르계 필라멘트는 필라멘트의 가공처리 여부와 상관없이 폴리에스테르 성분을 포함하는 것을 한정하지 않고 사용할 수 있다. Regardless of whether the filament is processed or not, the polyester-based filament can be used without limitation including a polyester component.
본 발명에 따른 환편(CIRCULAR KNIT) 조직 편성 작업은 상기 인터레이스사를 양면 인터록 또는 양면 이중지 조직으로 환편할 수 있으며, 생지 중량이 150~500g/YD가 되도록 게이지를 조정하면서 편성하여 편성물을 제조할 수 있다. CIRCULAR KNIT knitting operation according to the present invention can be performed by kneading the interlaced yarn into double-sided interlock or double-sided double-sided structure while controlling the gauge weight to be 150 to 500 g / YD, .
이후 상기 편성물을 고온의 유기 용매에 일정 시간 침지하여 수축시키는 수축 공정을 수행할 수 있다. Thereafter, a shrinking process may be performed in which the knitted fabric is dipped in a high-temperature organic solvent for a certain period of time and shrunk.
상기 유기 용매는 바람직하게 디메틸설폭사이드(DMSO, Dimethyl Sulfoxide) 또는 디메틸아세트아미드(DMAc, Dimethyl Acetamide)이다. The organic solvent is preferably dimethylsulfoxide (DMSO) or dimethylacetamide (DMAc).
침지할 때에 70 ~ 100℃, 2 ~ 10 분간의 조건에서 실시하는 것이 수축률이 증대되면서도 편성물의 손상이 발생하지 않을 수 있다. If it is carried out under the conditions of 70 to 100 DEG C for 2 to 10 minutes at the time of immersion, the shrinkage ratio may be increased and the damage of the knitted fabric may not occur.
일반적으로 열수에 의한 폴리에스테르 섬유의 수축 방법은, 폴리에스테르 섬유가 지니는 열 이력에 의해 일정하고 보편적인 수축 거동을 나타내므로, 수축률을 증대하는데 한계가 있다. 또한, 수축률의 증대를 위해서는 더 많은 열 이력을 주어야 하는 문제점이 있다. Generally, the method of shrinking polyester fibers by hot water has a certain and universal shrinkage behavior due to the thermal history of the polyester fibers, and thus there is a limit to increase the shrinkage rate. Further, in order to increase the shrinkage rate, there is a problem that more heat history should be given.
본 발명에서는 폴리에스테르 섬유를 고온의 유기 용매로 처리하여 폴리에스테르 섬유의 열 이력에 상관없이 처리 조건에 따라 수축률을 열 이력 이상의 수준으로 증대할 수 있다. In the present invention, the polyester fiber can be treated with a high-temperature organic solvent to increase the shrinkage rate to a level higher than the thermal hysteresis according to the treatment conditions regardless of the thermal history of the polyester fiber.
이와같은 수축에 의해 편성물의 밀도가 더욱 증가하므로, 비침이 억제되고 표면에서 연삭에 의해 모우 발생의 정도를 조정하여 외관 특성이 다양하게 나타나도록 할 수 있다. 이로 인해 최종적으로 인공피혁에서 외관품질과 촉감이 향상될 수 있다. Since the density of the knitted fabric is further increased by such shrinkage, the non-impression is suppressed and the degree of the occurrence of the kneading can be adjusted by grinding on the surface, so that the appearance characteristics can be varied. As a result, the appearance quality and feel of artificial leather can be improved finally.
이후 상기 편성물을 상압 감량기에서 2% 농도의 수산화나트륨(20g/L) 용액을 사용하여 70~95℃에서 20~40분간 처리함으로써 상기 해도사의 해성분이 용출된 극세화 섬유의 편성물을 얻을 수 있다. Thereafter, the knitted fabric is treated with a solution of sodium hydroxide (20 g / L) at a concentration of 2% in an atmospheric pressure reducing apparatus at 70 to 95 ° C for 20 to 40 minutes to obtain a knitted fabric of microfine fibers eluted from the marine sea component.
이때, 편성물의 겉보기 밀도는 0.2~0.6g/㎤이 되도록 하는 것이 바람직하다. At this time, the knitted fabric preferably has an apparent density of 0.2 to 0.6 g / cm 3.
이후 상기 편성물을 폴리우레탄 용액에 침지하여 폴리우레탄을 편성물에 함침시켜 함침포를 얻는 탄성체 함침 공정을 실시할 수 있다.Thereafter, the knitted fabric is immersed in a polyurethane solution to impregnate the knitted fabric with the polyurethane to obtain an impregnation step.
폴리우레탄의 함침량은 인공피혁에서 2~30 중량%인 것이 바람직한데, 함침량이 2 중량% 미만이면 인공피혁의 탄력성이 저하하고, 30 중량%를 초과하면 편성물 고유의 스웨이드 효과보다 폴리우레탄에 의한 느낌이 나타나고 딱딱해져서 바람직하지 못하다. If the amount of impregnation is less than 2% by weight, the elasticity of the artificial leather is deteriorated. When the amount of impregnation is more than 30% by weight, the amount of impregnated polyurethane is less than the inherent suede effect of the knitted fabric. Feeling appears and becomes hard and is not desirable.
이후, 상기 함침포의 표면을 샌드페이퍼를 이용하여 연삭하여 기모를 형성하고, 염색 후가공을 거쳐 인공피혁을 제조할 수 있다. Thereafter, the surface of the impregnated cloth is ground using a sandpaper to form a brushed surface, and artificial leather can be manufactured through a post-staining process.

상기 실시예 및 비교예에서 제조된 인공피혁에 대해 하기 평가방법에 따라 그 특성을 평가하여 그 결과를 하기 표 1에 나타내었다. The properties of the artificial leather prepared in the above Examples and Comparative Examples were evaluated according to the following evaluation methods, and the results are shown in Table 1 below.
1. 면적 수축률1. Area Shrinkage
가로 1,500mm, 세로 2,500mm의 원단을 수축시켜 수축 전·후의 면적 변화를 백분율로 나타낸다. Shrinkage of 1,500 mm in width and 2,500 mm in length is indicated by the percentage change in the area before and after shrinkage.
면적 수축률(%) = (수축 전 면적 - 수축 후 면적 ) / 수축 전 면적 × 100Area Shrinkage (%) = (Area before shrinkage - Area after shrinkage) / Area before shrinkage × 100
2. 동마찰 계수 2. Coefficient of friction
인공피혁을 시료로 하여 ASTM D 1894에 따라 동마찰 계수 측정장비를 이용하여 하중 100gf, 인장속도 500 ㎜/분의 조건에서 측정한다. Using an artificial leather as a specimen, it is measured under the conditions of a load of 100 gf and a tensile speed of 500 mm / min using a dynamic friction coefficient measuring instrument according to ASTM D 1894.
동마찰 계수가 작아질수록 시료의 표면에서 매끄러움과 부드러움이 우수해진다. As the coefficient of dynamic friction decreases, the smoothness and softness of the surface of the sample become excellent.
상기 표 1로부터, 본 발명에 따른 실시예에 의한 것이 비교예의 의한 것보다 면적 수축률이 현저히 향상되는 것이 확인된다. It can be seen from Table 1 that the area shrinkage ratio according to the embodiment of the present invention is significantly improved as compared with the comparative example.
이로 인해 실시예에 의한 인공피혁이 비교예의 것보다 동마찰 계수가 현저히 저하하는 것도 확인된다. As a result, it was also confirmed that the artificial leather according to the examples significantly lowered the coefficient of dynamic friction than the comparative example.
이와 같이 동마찰 계수가 저하하므로 본 발명의 인공피혁은 표면에서 매끄러움과 부드러움이 우수해져서 촉감 품질이 향상된 인공피혁의 제공이 가능해진다.
