Description
본 발명은 고신축성을 갖는 투습방수원단 및 그 제조방법에 관한 것으로, 특히 와프 니트(warp knit)원단에 투습방수처리를 하여 기존의 투습방수원단이 갖고 있는 투습성, 방수성 및 방한성을 향상시키면서 고신축성이며 가볍고 착용감을 향상시킨 고신축성을 갖는 투습방수원단 및 그 제조방법에 관한 것이다.The present invention relates to a moisture-repellent waterproof fabric having a high elasticity and a method for manufacturing the same, and in particular, to improve the moisture-permeable, waterproof and cold-resistance of the conventional moisture-repellent waterproof fabric by performing a waterproof waterproof treatment on a warp knit fabric. And it relates to a moisture-repellent waterproof fabric and a method of manufacturing the same having a high elasticity light and improved fit.
일반적으로 투습방수원단은 외부의 빗물 등을 방수하면서 동시에 내부에서 발생하는 땀 등을 외부로 배출하는 원단으로 주로 스포츠용 의류의 제작에 사용되고 있다.In general, the waterproof fabric is a fabric for discharging the external rain water and at the same time to discharge the sweat generated from the inside to the outside is mainly used in the production of sports clothing.
이와 같은 종래의 투습방수원단은 주로 직물 원단상에 습식 폴리우레탄 수지 조성물을 플로팅 나이프(floating knife) 또는 나이프 오버 롤(knife over roll) 방식으로 직접 도포한 후, 건식 또는 습식공정을 거쳐 응고시켜 코팅층을 형성하는 방법을 통해 제조되어 왔다.The conventional water-permeable waterproof fabric is mainly coated with a wet knife (floating knife or knife over roll) method of the wet polyurethane resin composition on the fabric fabric, and then solidified through a dry or wet process coating layer It has been prepared through the method of forming a.
그런데 이와 같은 투습방수원단은 직물 원단을 이용하여 투습방수처리를 하였기 때문에 촉감이 부드럽지 못하고 접힘 소음이 심하며, 드레이프(drape)성이 양호하지 못하였다.However, because the moisture-permeable waterproof fabric was waterproof fabricated using a fabric fabric, the touch was not soft, the folding noise was severe, and the drape was not good.
더욱이 종래의 투습방수원단은 신축성이 거의 없는 직물로 제조되어 있어 이 원단으로 제작된 스포츠 웨어를 입고 격렬한 모션을 취할 경우, 사용자는 큰 구속감을 느끼게 되므로 운동 중 매우 답답한 느낌을 갖게 되었다.In addition, the conventional moisture-repellent fabric is made of a fabric with almost no elasticity, so when the user wears a sports wear made of this fabric to take a vigorous motion, the user feels a great restraint and thus feels very stuffy during exercise.
따라서 이러한 문제를 해결하기 위해 직물원단에 신축성을 발생시킬 수 있는 고무 원사를 혼섬하여 투습방수원단을 제직 생산하고 있으나 이 또한 여전히 직물 조직으로서 갖고 있는 신축성의 한계를 가지고 있었다.Therefore, in order to solve this problem, weaving rubber yarns that can generate elasticity in the fabric fabric, weaving the waterproof moisture-proof fabric, but this also had a limit of elasticity as a fabric structure.
특히, 고무 원사를 혼용함에 따라 일반 직물보다 높은 중량을 갖게 되어 스포츠 웨어 즉, 등산복, 스키복 또는 낚시복 등 장시간 입고 있어야 하는 경우 그 무게로 인하여 사용자의 몸에 무리를 주는 문제점이 있었다.In particular, when the rubber yarn is mixed, it has a higher weight than ordinary fabrics, and thus, when it is necessary to wear sportswear, that is, mountain climbing clothes, ski clothes or fishing clothes for a long time, there is a problem in that the user's body due to its weight.
또한 종래의 또 다른 투습방수원단은 직물원단을 테프론계 또는 불소계 발수제로 선발수처리한 후, 투습방수 필름을 생지 원단에 접착하였기 때문에 직물원단의 표면에 발수제층이 형성되어 있어 필름의 접착력이 저하되었고 이에 따라 필름이 직물 원단으로부터 박리되는 문제점이 있었다. In addition, another conventional moisture-repellent fabric has a water repellent layer formed on the surface of the fabric fabric because the water-repellent treatment of the fabric fabric with a Teflon-based or fluorine-based water repellent, and then adhered to the dough fabric to reduce the adhesion of the film Accordingly, there was a problem that the film is peeled from the fabric fabric.
따라서 상기와 같은 문제점을 해결하기 위해, 본 발명의 목적은 와프 니트원단에 투습방수처리를 하여 기존의 투습방수원단이 갖고 있는 투습성, 방수성 및 방한성을 향상시키면서 고신축성이며 가볍고 착용감을 향상시킨 고신축성을 갖는 투습방수원단 및 그 제조방법을 제공하는 데 있다.Therefore, in order to solve the above problems, an object of the present invention is a high elasticity, light and high elasticity by improving the moisture permeability, waterproof and cold protection that the existing moisture-permeable waterproof fabric has a waterproof breathable treatment to the warp knitted fabric It is to provide a moisture-proof waterproof fabric and a method for producing the same.

이때, 상기 니트원단을 편직하는 단계는 폴리에스터 트리코트 원사 30데니어 24필라의 672콘을 권취하는 단계와, 상기 권취된 원사를 편직장치의 L1에 조직 1-0 1-2로 배열하는 단계와, 상기 권취된 원사를 편직장치의 L2에 조직 2-3 1-0으로 배열하는 단계와, 상기 L1, L2에 배열된 원사를 편직장치에 의해 편직하는 단계로 이루어진다.At this time, the step of knitting the knitted fabric is winding the 672 cones of 30 denier 24 pillar polyester tricot yarn, and arranging the wound yarn in a tissue 1-0 1-2 in L1 of the knitting device; , The wound yarn is arranged in a tissue 2-3 1-0 in L2 of the knitting device, and the yarns arranged in the L1, L2 knitting step by the knitting device.
또한 상기 편직되는 니트원단은 폭이 73인치∼126인치로 이루어지며, 바람직하게는 105인치∼126인치로 편직하는 것이 바람직하다.In addition, the knitted fabric to be knitted is made of 73 inches to 126 inches in width, preferably 105 to 126 inches to knit.
더욱이 상기 니트원단 일면에 도포되는 접착제는 우레탄수지로 이루어지며, 니트원단에 라미네이팅되는 수지필름은 폴리우레탄 수지로 이루어진다.Furthermore, the adhesive applied to one surface of the knit fabric is made of urethane resin, and the resin film laminated on the knit fabric is made of polyurethane resin.
한편, 본 발명에 따른 다른 특징에 의하면, 편직장치를 통해 니트원단과, 상기 니트원단 일면에 도포되는 접착제와, 상기 접착제가 도포된 니트원단에 라미네이팅 처리를 통해 접착되는 수지필름으로 구성된다.On the other hand, according to another feature according to the invention, the knitted fabric through the knitting device, the adhesive is applied to one surface of the knitted fabric, and the resin film is bonded to the knitted fabric coated with the adhesive through a laminating process.

따라서, 상기한 본 발명은 니트원단에 투습방수필름을 라미네이팅처리함에 따라 신축성을 크게 향상시키는 것은 물론 가볍고 유연한 질감을 제공함에 따라 스포츠 웨어를 제작할 경우 뛰어난 착용감을 지닐 수 있으며, 필름이 니트원단으로부터 박리되는 것을 방지하여 제품의 불량률을 저하시킬 수 있다.Therefore, the present invention as described above greatly improves the elasticity by laminating the moisture-permeable waterproof film on the knitted fabric, as well as providing a light and flexible texture can have an excellent fit when producing sportswear, the film peeled from the knitted fabric It can be prevented to reduce the defective rate of the product.
(실시예)(Example)
첨부된 도 1은 본 발명에 따른 고신축성을 갖는 투습방수원단의 제조공정을 나타내는 흐름도이고, 도 2는 본 발명에 따른 제조공정을 통해 생산된 투습방수원단의 구조를 개략적으로 나타내는 단면도이다.1 is a flowchart illustrating a manufacturing process of a highly elastic moisture permeable waterproof fabric according to the present invention, and FIG. 2 is a cross-sectional view schematically illustrating a structure of the moisture permeable waterproof fabric produced through the manufacturing process according to the present invention.
이하, 첨부된 도 1 및 도 2를 참고하여 본 발명의 고신축성을 갖는 투습방수원단 및 그 제조방법을 설명하면 다음과 같다.Hereinafter, with reference to the accompanying Figures 1 and 2 will be described a moisture-permeable waterproof fabric and a manufacturing method having a high elasticity of the present invention.
본 발명에 따른 투습방수원단은 편직장치 예를 들면, 독일산 칼마이어 HKS53 타입 32G/G 기종에 30데니어 24필라의 마이크로 원사 672본을 권선하여 콘을 형성한다.The moisture-permeable waterproof fabric according to the present invention forms a cone by winding a knitting device, for example, 30 yarns of 30 denier and 24 pillar micro yarns on a Kalmeyer HKS53 type 32G / G model made in Germany.
이어서, 편직장치의 제직바는 2바(bar)로 하고 조직은 L1에 1-0 1-2로 배열하고, L2에 2-3 1-0으로 조직 배열하여 아래 표 1과 같은 니트원단을 편직한다(S1).Subsequently, the weaving bar of the knitting device is 2 bar (bar) and the tissue is arranged in 1-0 1-2 in L1, the tissue is arranged in 2-3 1-0 in L2 to knit the knitted fabric as shown in Table 1 below (S1).
이와 같이 니트원단의 폭은 73인치∼126인치로 이루어지며, 폭이 73인치 이하인 경우에는 신축성이 떨어지고, 폭이 126인치 이상은 복원력이 저하되므로, 바람직하게는 폭을 105인치∼126인치로 형성하는 것이 좋다.Thus, the width of the knitted fabric is made of 73 inches to 126 inches, the width is less than 73 inches elasticity is reduced, the width is more than 126 inches, the restoring force is lowered, preferably formed width 105 to 126 inches Good to do.
이 경우, 편직예 4는 밀도를 편직예 3보다 5.2 EA/cm 적게 설정하여 편직한 것으로 중량은 50 g/y 적으면서도 폭방향 신장률은 2.3% 향상되었으며, 이에 따라 동일한 폭의 니트원단을 편직 시에 밀도를 달리할 경우 중량을 조절할 수 있다.In this case, the knitting example 4 is knitted by setting the density of 5.2 EA / cm less than the knitting example 3, the weight is 50 g / y, while the widthwise elongation is improved by 2.3%, so that when knitting the same width knit fabric If the density is different, the weight can be adjusted.
이후 공정은 도 1 및 표 1에 나타낸 폭 126인치 니트원단을 사용하여 설명한다.The process is then described using the 126 inch wide knit fabric shown in FIG. 1 and Table 1.
상기와 같이 편직장치 효율 80%, 기계회전수 1500rpm으로 운용하여 얻어지는 126인치 폭에 165g/y인 니트원단(1)은 신축성을 부여받도록 약 185℃에서 1차 열처리되어 최대한으로 축소된다(S2).As described above, the knitted fabric 1 having a width of 165 g / y in a 126 inch width obtained by operating at a knitting device efficiency of 80% and a machine speed of 1500 rpm is first heat-treated at about 185 ° C. to be given elasticity and is reduced to the maximum (S2). .
그 후, 축소된 상기 니트원단(1)은 염색공정을 실시하게 되는데 이때 염색 견뢰도를 높이기 위해 염색온도를 50분 동안 상온에서부터 서서히 상승시켜 약 135℃까지 욕중에서 위킹(wiking)처리를 함께 실시한다(S3).Thereafter, the reduced knitted fabric 1 is subjected to a dyeing process, in which the dyeing temperature is gradually raised from room temperature for 50 minutes to increase the color fastness, and the wicking process is performed in a bath up to about 135 ° C. (S3).
더욱이 상기 니트원단(1)이 위킹처리를 통해 표면의 불순물이 제거된 상태이므로 발수제의 흡습이 용이하도록 종래와 달리 후발수 처리를 하였으며, 이때 상기 니트원단은 위킹처리를 통해 흡습기능이 향상되고 아울러 원단(1) 표면의 불순물이 제거된다.Furthermore, since the surface of the knit fabric 1 has been removed through the wicking treatment, the knit fabric 1 has been subjected to a post-water repellent treatment to facilitate moisture absorption of the water repellent agent, and the knitted fabric has improved hygroscopic function through the wicking treatment. Impurities on the surface of the fabric 1 are removed.
이어서, 유연제 및 기타 불순물에 오염되지 않도록 주의하면서 니트원단(1)을 약 190℃에서 편직장치를 45rpm으로 운영하면서 2차 열처리를 실시하여 58인치에 190g/y 정도로 최대 축소 가공하며(S5), 이때 2차 열처리 중에 니트원단은 폭방향의 양측의 주변을 정리하기 위한 변사 커팅처리를 한다.Subsequently, while processing the knit fabric 1 at about 190 ° C. while operating the knitting apparatus at 45 rpm while being careful not to be contaminated with the softening agent and other impurities, a maximum heat treatment is performed at 58 inches to 190 g / y (S5). At this time, during the second heat treatment, the knit fabric is subjected to a metabolic cutting process to clean up the periphery of both sides in the width direction.
이 경우, 상기 니트원단(1)은 하기에 설명되는 라미네이팅(laminating)처리 시 변사의 말림을 방지하고 동시에 불량률을 최소화하도록 변사 부위는 강수지처리를 한다(S6).In this case, the knitted fabric 1 is treated with a resin part to prevent the curling of lattice during the laminating process described below and to minimize the defective rate at the same time (S6).
그 후, 불순물이 제거된 상태의 니트원단 일면에 접착제 예를 들면, 우레탄수지로 이루어진 접착제(3)를 도포하고 여기에 투습 및 방수성을 갖는 폴리우레탄 수지필름(5)을 접착하는 라미네이팅 처리(S7)를 거쳐 투습방수원단을 완성한다.Thereafter, a laminating treatment for applying an adhesive 3, for example, a urethane resin, to one surface of the knitted fabric in which impurities are removed and adhering the polyurethane resin film 5 having moisture permeability and water resistance thereto (S7). Complete the breathable waterproof fabric through).
이와 같이 이루어진 투습방수원단은 표면에 불순물이 제거된 니트원단(1)에 필름(5)을 접착함에 따라 필름의 접착강도를 상승시킬 수 있고 이에 따라 필름(5)이 니트원단(1)으로부터 박리되는 것을 방지할 수 있다.The moisture-permeable waterproof fabric made in this way can increase the adhesive strength of the film by adhering the film 5 to the knitted fabric 1 from which impurities are removed from the surface, and thus the film 5 is peeled from the knitted fabric 1. Can be prevented.
한편, 상기 우레탄수지 접착제(3)는 일반적으로 친수성을 갖고 있으며, 폴리우레탄 수지필름(5)은 친수성의 물질을 공중합시켜 모세관현상에 의해 미세기공을 통해 투습/방수기능을 갖는다.Meanwhile, the urethane resin adhesive 3 generally has hydrophilicity, and the polyurethane resin film 5 copolymerizes a hydrophilic material to have a moisture permeability / waterproof function through micropores by capillary action.
이에 따라 상기 투습방수원단으로 스포츠웨어를 제작하여 이를 착용한 사용자는 자신의 인체에서 분비되는 수분이 친수성을 띠는 폴리우레탄 수지필름으로 흡수되고, 동시에 모세관 현상으로 인해 우레탄수지 접착제 층으로 신속하게 확산되고 이어서 고무사 원사가 혼섬되지 않은 순수한 폴리에스터 니트원단(1)의 소수작용에 의해 외부로 빠르게 배출되며 아울러 니트원단의 특징인 다공구조조직의 영향으로 빠르게 건조된다.Accordingly, the user who wears the sportswear by using the waterproof fabric is absorbed by the polyurethane resin film having the hydrophilicity of the human body, and at the same time, it rapidly spreads to the urethane resin adhesive layer due to the capillary phenomenon. Then, the rubber yarn yarn is quickly discharged to the outside by the hydrophobic action of the pure polyester knit fabric (1) that is not mixed with the yarn, and also rapidly dried under the influence of the porous structure that is characteristic of the knit fabric.
본 발명에 따른 상기 고신축성을 갖는 투습방수원단은 조직밀도의 조정으로 투습방수원단을 사용하려는 용도에 따라 그 신축성을 조정하는 것이 가능하다.The moisture-permeable waterproof fabric having high elasticity according to the present invention can adjust its elasticity according to the intended use of the moisture-proof waterproof fabric by adjusting the tissue density.
한편, 표 2는 상기와 같은 방법을 통해 얻어진 본 발명의 투습방수원단(시료 1)과 종래의 직물스판(고무사)원단(시료 2) 즉, 고무사를 섞어 편직한 직물원단에 필름을 접착시킨 투습방수원단을 한국의류시험연구원(Korea Apparel Testing and Research Institute, http://www.katri.re.kr)에 의뢰하여 얻은 시험성적서를 바탕으로 각각의 신장률 및 중량을 나타낸 것이다.On the other hand, Table 2 is a mixture of the moisture-permeable waterproof fabric (Sample 1) and the conventional fabric span (rubber yarn) fabric (Sample 2), that is, rubber yarn of the present invention obtained through the method as described above to adhere the film to the knitted fabric fabric The elongation and weight of the moisture-permeable waterproof fabric was obtained from a test report obtained from the Korea Apparel Testing and Research Institute (http://www.katri.re.kr).
(단, 시험조건은 시험편 5×30cm 5매, 파지거리 200 ㎜, 인장속도는 100 ㎜/min이고, 시료 1은 니트원단에 투습방수필름을 부착시킨 본 발명에 따른 투습방수원단, 시료 2는 직물원단에 투습방수필림을 부착시킨 종래의 투습방수원단) (However, the test conditions are 5 × 30 cm 5 specimens, 200 mm gripping distance, the tensile speed is 100 mm / min, Sample 1 is a moisture-permeable waterproof fabric according to the present invention, the sample 2 is attached to the waterproof fabric on the knitted fabric, Conventional moisture-proof waterproof fabric with moisture-proof waterproof film attached to fabric fabric)
동일한 폭과 장으로 이루어진 시료 1 및 2를 시험을 통해 상호 비교한 결과 표 2와 같이 시료 1의 폭방향 신장률은 시료 2에 비하여 약 1.5배 향상되었고, 시료 1의 장방향 신장률은 시료 2에 비하여 9배가 향상되었다.As a result of comparing the samples 1 and 2 having the same width and length through the test, the widthwise elongation of sample 1 was improved about 1.5 times compared to sample 2 as shown in Table 2, and the longitudinal elongation of sample 1 was greater than that of sample 2. Nine times improved.
또한 시료 1의 중량은 시료 2에 비하여 약 0.5배 가볍게 나타났다.In addition, the weight of sample 1 was about 0.5 times lighter than that of sample 2.
한편, 종래 및 본 발명에 따른 투습방수원단의 내수압 및 투습도는 직물원단 또는 니트원단에 의해 결정되는 것이 아니라 상기 수지필름(5)에 의해 차이가 발생하는데, 내수압 및 투습도에 따라 저/중/고기능 수지필름 중에서 내수압이 10000 ㎜H2O이고 투습도가 10000 g/㎡/24h 이상인 고기능 수지필름을 본 발명에 다른 투습방수원단에 사용하여 이에 대한 내수압 및 투습도를 시험을 한국원사직물검사소(FITI TESTING & RESEARCH INSTITUTE, http://www.fiti.re.kr)에 의뢰하였다.On the other hand, the water pressure and moisture permeability of the moisture-permeable waterproof fabric according to the prior art and the present invention is not determined by the fabric fabric or knit fabric, but the difference occurs by the resin film (5), depending on the water pressure and moisture permeability low / medium / high function Among the resin films, a high-performance resin film having a water resistance of 10000 mmH 2 O and a water vapor transmission rate of 10000 g / m 2 / 24h or more is used in another moisture-permeable waterproof fabric according to the present invention.
