About.
최근 아웃도어용품의 수요 및 관심이 증가됨에 따라 다기능성을 가지는 아웃도어용 섬유제품이 다양하게 개발되고 있다. 이러한 아웃도어용 섬유제품에서 요구하는 신축성, 경량성, 통기성, 투습방수, 내구성의 성능을 겸비하는 복합 기능성 아웃도어 개발을 위한 다양한 연구가 진행되고 있으며, 그 일환으로 ①소재(세섬 이형이섬도 고강도 PET 기술), ②니트(고밀도 니트기술) 및 ③나노(친환경 나노 멤브레인 기술)의 융합 기술 개발이 진행되고 있다.In recent years, as the demand and interest of outdoor products increases, various textile products for outdoor use having multifunctionality are being developed. Various researches are being conducted to develop a complex functional outdoor that combines the performance of elasticity, light weight, breathability, moisture permeability, and durability required by these outdoor textile products. PET technology), ② knit (high-density knit technology) and ③ nano (environmentally friendly nano membrane technology) are being developed.
현재 겉옷용 소재로서 다기능성 발현을 위해 직물, 편직물 등과 고기능성 필름을 라미네이팅시킨 라미네이팅 원단이 널리 사용되고 있으며 최근에는 기존 기능성 필름이 가지지 않는 통기성을 가지는 Nano-membrane 필름을 적용하는 기능성 가공제품들이 만들어지고 있다.Currently, as a material for outerwear, laminating fabrics laminated with high-functional films such as fabrics, knitted fabrics, etc. are widely used to express versatility. Recently, functional processed products that apply nano-membrane films that have breathability that existing functional films do not have have been made. have.
상기 기능성 가공제품을 제조하는 종래 기술로는 직물과 편물의 일면에 접착제를 전면 코팅한 후, 그 위에 폴리우레탄 박막 필름을 올려 압착해주는 방법이 사용되었으나, 상기 종래방법은 편물의 일면에 접착제를 전면 코팅하기 때문에 편물과 폴리우레탄 박막 필름 간의 접착강도는 우수하지만 편물이 갖는 우수한 통기성, 촉감 및 드레이프성이 크게 손상되는 문제점이 있었다.As a conventional technique for manufacturing the functional processed product, a method of applying an adhesive on one side of a fabric and a knitted fabric, and then placing a polyurethane thin film on it and compressing it, was used. Because of the coating, the adhesive strength between the knitted fabric and the polyurethane thin film is excellent, but there is a problem in that the excellent breathability, touch and drape properties of the knitted fabric are greatly damaged.
또 다른 종래기술로서는 메쉬로울러 등을 사용하여 직물과 편물의 일면에 접착제를 도트(Dot) 형태로 코팅한 후 그 위에 폴리우레탄 박막 필름을 올려 압착해 주는 방법이 사용되었으나, 상기 종래방법은 도트(Dot) 코팅 방식으로 편물의 일면에 접착제가 도트(Dot) 형태로 코팅되기 때문에 편물이 갖는 우수한 통기성, 촉감 및 드레이프성을 그대로 유지할 수는 있지만, 편물과 폴리우레탄 박막 필름 간의 박리강도가 크게 저하되고 라미네이팅 원단의 형태안정성이 불량해지는 문제가 있었다.As another conventional technique, a method in which an adhesive is coated on one side of fabrics and knitted fabrics in a dot form using a mesh roller, etc., and then a polyurethane thin film is placed thereon and compressed, is used. Because the adhesive is coated on one side of the knitted fabric in a dot form by Dot) coating method, the excellent breathability, touch and draping properties of the knitted fabric can be maintained, but the peel strength between the knitted fabric and the polyurethane thin film is greatly reduced. There was a problem that the shape stability of the laminating fabric became poor.
그러므로 본 발명에서는 Nano-membrane 박막 필름과 편직물을 라미네이팅 하여 기능성 가공제품을 제조할 경우 편물이 갖는 우수한 통기성, 촉감 및 드레이프성은 그대로 유지하면서 편직물에 핫멜트 접착제 패턴을 형성하여 Nano-membrane 박막 필름과 편물의 접착성을 향상시켜 라미네이팅 원단의 형태안정성과 박리강도를 개선시키는 것을 기술적과제로 한다.Therefore, in the present invention, in the case of manufacturing a functional processed product by laminating a nano-membrane thin film and a knitted fabric, a hot melt adhesive pattern is formed on the knitted fabric while maintaining excellent air permeability, touch and drape properties of the knitted fabric. The technical task is to improve the adhesion and improve the shape stability and peel strength of the laminating fabric.
그러므로 본 발명에 의하면, 섬유상기재의 표면에 형성된 핫멜트 접착제 패턴 및 상기 핫멜트 접착제 패턴에 접착된 Nano-membrane 박막 필름을 포함하는 투습방수원단에 있어서, 상기 섬유상기재는 접착력 향상용 폴리우레탄계 접착제가 편면코팅된 환편물이며, 상기 핫멜트 접착제 패턴은 다수의 원형 또는 타원형 도트인 것을 특징으로 하는 박리강도가 우수한 투습방수환편물이 제공된다.Therefore, according to the present invention, in the moisture-permeable waterproof fabric comprising a hot-melt adhesive pattern formed on the surface of a fibrous substrate and a nano-membrane thin film adhered to the hot-melt adhesive pattern, the fibrous substrate is coated with a polyurethane-based adhesive for improving adhesion. It is a circular knitted fabric, and the hot-melt adhesive pattern is provided with a moisture-permeable waterproof circular knitted fabric having excellent peel strength, characterized in that a plurality of circular or elliptical dots.
이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명은 박리강도가 우수한 투습방수원단에 관한 것으로서 섬유상기재의 표면에 형성된 핫멜트 접착제 패턴의 개선을 통해 Nano-membrane 박막 필름의 박리강도를 향상시킨 투습방수환편물에 관한 것이다.The present invention relates to a moisture-permeable waterproof fabric having excellent peel strength, and relates to a moisture-permeable and waterproof circular knitted fabric that improves the peel strength of a nano-membrane thin film through improvement of a hot melt adhesive pattern formed on the surface of a fiber substrate.
본 발명의 박리강도가 우수한 투습방수환편물은 접착력 향상용 폴리우레탄계 접착제가 편면코팅된 환편물의 표면에 다수의 원형 또는 타원형 도트의 핫멜트 접착제 패턴이 형성되고, 상기 핫멜트 접착제 패턴에 Nano-membrane 박막 필름이 접착된 투습방수환편물이다. The moisture-permeable waterproof circular knitted fabric of the present invention having excellent peel strength has a plurality of circular or elliptical dots hot-melt adhesive patterns formed on the surface of a circular knitted fabric coated with a single-sided polyurethane-based adhesive for improving adhesion, and a nano-membrane thin film film on the hot-melt adhesive pattern This is the bonded breathable waterproof circular knitted fabric.
본 발명의 섬유상기재인 상기 환편물은 30~45d/24~72f 폴리에스테르사와 20~30d 스판덱스모노필라멘트를 1:1 ~ 2:1로 공급하여, 루프장 70~100㎜, 환편속도 15~16rpm의 조건으로 30인치/48게이지의 양면환편기로 양면인터록조직으로 환편된 환편물이 바람직하다.The circular knitting material of the present invention is a 30-45d/24-72f polyester yarn and 20-30d spandex monofilament supplied in a ratio of 1:1 to 2:1, and a loop length of 70-100 mm, a circular knitting speed of 15-16 rpm. Under the condition of, a circular knitted fabric with a double-sided interlock structure with a 30 inch/48 gauge double-sided circular knitting machine is preferable.
본 발명의 고밀도환편물의 제조방법에서 사용되는 원사는 30~45d/24~72f 폴리에스테르사와 20~30d 스판덱스모노필라멘트를 사용하는데, 30~45d/24~72f 폴리에스테르사와 20d 스판덱스모노필라멘트를 1:1 또는 2:1로 공급하여 편성하게 된다. The yarn used in the manufacturing method of the high-density circular knitted fabric of the present invention uses 30-45d/24-72f polyester yarn and 20-30d spandex monofilament, 30-45d/24-72f polyester yarn and 20d spandex monofilament 1 It is organized by feeding it in :1 or 2:1.
상기 폴리에스테르사는 폴리에스테르 DTY사 또는 폴리에스테르 ATY사인 것이 바람직하며, 30~45d/24~72f 폴리에스테르사와 20~30d 스판덱스모노필라멘트를 1:1~2:1로 공급하여 신축회복율 보완을 할 수 있으며, 루프장 및 신축 회복력에 대한 문제로 인해 원단이 늘어난 형태로 변형되는 불량을 방지할 수 있다.The polyester yarn is preferably polyester DTY yarn or polyester ATY yarn, and by supplying 30 to 45d/24 to 72f polyester yarn and 20 to 30d spandex monofilament in a ratio of 1:1 to 2:1, it is possible to supplement the elasticity recovery rate. In addition, it is possible to prevent defects in which the fabric is deformed in an elongated form due to problems with the loop length and elasticity and resilience.
\특히, 본 발명과 같이 고밀도로 편직을 진행시 폴리에스테르사가 앞면과 뒷면, 스판덱스사가 뒷면으로 위치하면서 규칙적으로 편성되어야 결점을 최소화할 수 있기 때문에 yarn carrier를 앞뒤로 조정하여 원사 인입 각도를 조절하고, yarn guide와 바늘 사이 0.3mm의 간격으로 하여야 편직시 원단의 불량이 생기지 않는다.본 발명에서 환편하는 조건은 루프장 70~100㎜, 환편속도 15~16rpm의 조건으로 30인치/48게이지의 양면환편기로 양면인터록조직으로 환편한다. \ In particular, when knitting at high density as in the present invention, the polyester yarn must be regularly knitted while being positioned on the front and back sides, and the spandex yarn on the back side to minimize defects, so the yarn carrier is adjusted back and forth to adjust the yarn entry angle, The yarn guide and the needle must be spaced at a distance of 0.3mm so that there is no defect in the fabric during knitting. The condition for circular knitting in the present invention is a 30-inch/48-gauge double-sided circular knitting machine with a loop length of 70 to 100 mm and a circular knitting speed of 15 to 16 rpm. It is circular knitting with double-sided interlock structure.
본 발명에서 루프장은 편물 제품 형성의 주요 요소로써 동일 조건하에서 루프장이 길수록 원단 밀도가 적어져 루즈(loose)해지고 단위면적당 중량이 낮아지며 원단폭은 넓어진다. 반대로 루프장이 짧을수록 밀도가 많아지며 원단은 타이트(tight)해지고 단위면적당 중량이 높아지며 원단폭이 좁아진다. 따라서 본 발명에서는 루프장을 70~100㎜로 조절하여 최적 편물 루프장을 선정하여 원단 올이 풀리지 않는 깨끗한 표면상태를 유지하도록 한다. 루프장 70㎜미만에서는 실린더와 다이얼간의 좁은 간격으로 루프형성이 어려워 바늘이 연달아 부러져 편직 자체가 불가할 수 있고, 100㎜초과시에서는 원단 비침이 심하고, 올이 나가는 running 현상 및 가공 이후 코스(Couse) 방향으로 줄이 나타나는 위단 현상이 발생할 우려가 있다.In the present invention, the loop length is a major factor in forming a knitted product, and under the same conditions, the longer the loop length, the lower the fabric density, resulting in loose, lower weight per unit area, and wider fabric width. Conversely, the shorter the loop length, the higher the density, the tighter the fabric, the higher the weight per unit area, and the narrower the fabric width. Therefore, in the present invention, by adjusting the length of the loop to 70 to 100 mm, the optimal knitted loop length is selected to maintain a clean surface condition in which the fabric is not loosened. If the length of the loop is less than 70 mm, it is difficult to form a loop due to the narrow gap between the cylinder and the dial, and the needle may break in succession and knitting itself may be impossible. If the length exceeds 100 mm, the fabric is severely reflected, running out, and the course after processing. There is a risk of occurrence of a top-down phenomenon in which lines appear in the direction.
상기 폴리에스테르사 및 스판덱스모노필라멘트는 사장력 3~5g으로 양면환편기에 공급되는 것이 바람직하다. 본 발명의 고밀도 환편제품은 상기와 같이 세섬사를 원사로 환편됨에 따라 원사 장력이 적합하지 않을 경우 스판덱스사만 절사되어 couse 방향으로 줄이 발생하는 불량이 빈번히 발생되므로 상기와 같이 사장력을 조절하여 정상적 루프를 생성하고 결점을 최소화하여 편직할 수 있어 바람직하다. 사장력 3g미만에서는 정상적 루프 생성이 되지 않아 바늘 구멍등의 결점이 발생하며, 5g초과시에는 편물에 위단이 발생하고, 큰 급사 장력으로 공급시 휠에서의 투입되는 장력과 바늘부분의 장력으로 인한 당김 현상으로 실이 터지는 절사 현상 및 바늘이 부러짐에 따라 편물 결점이 발생할 수 있다. The polyester yarn and spandex monofilament are preferably supplied to the double-sided circular knitting machine with 3 to 5 g of long-lasting force. In the high-density circular knitting product of the present invention, as described above, since fine yarn is circularly knitted into yarn, if the yarn tension is not suitable, only the spandex yarn is cut and a string occurs frequently in the couse direction. It is desirable to create a normal loop and to be able to knit with minimal defects. If the long-lasting force is less than 3g, the normal loop cannot be created, resulting in defects such as a needle hole, and if it exceeds 5g, the knitted fabric has a stomach edge, and when it is supplied with a large sudden yarn tension, it is pulled due to the input tension from the wheel and the tension of the needle. Knitting defects may occur as the thread bursts due to the phenomenon and the needle is broken.
본 발명의 편물의 안정적인 생산성 확보를 위해서는 공급되는 원사의 상기 장력뿐 아니라 최종 편물의 take-up 장력 균형 및 효율적인 편성 속도(rpm)등이 선정되어야 하는데, 편성속도는 15~16 rpm을 유지하여 환편하였으며, 최종 Take-up 장력은 원사의 섬도특성을 고려하여 30~35% 사이로 설정한다. In order to secure stable productivity of the knitted fabric of the present invention, not only the above tension of the supplied yarn, but also the balance of the take-up tension of the final knitted fabric and an efficient knitting speed (rpm) should be selected, and the knitting speed is circular knitting by maintaining 15 to 16 rpm. The final take-up tension is set between 30 and 35% in consideration of the fineness characteristics of the yarn.
본 발명의 상기 섬유상기재는 상기 환편물에 접착력 향상용 폴리우레탄계 접착제가 편면코팅된 환편물인데, 그라비아(Gravure) 로울러를 사용하여 무장력하에서 라미네이팅용 상기 편물의 일면에 접착제를 부분적으로 코팅하고 코팅된 편물을 80~120℃의 챔버와 180℃의 텐더를 30m/분의 속도로 통과시키면서 건조 및 열고정하여 통기성이 우수한 Nano-membrane 박막 필름의 라미네이팅시 안정적으로 편직물에 접착되도록 해주는 것이다. 상기 편직물은 나일론 섬유로 구성된 편물 등이고, 상기 접착력 향상용 코팅제는 폴리우레탄계 접착제를 사용할 수 있다.The fibrous substrate of the present invention is a circular knitted fabric in which a polyurethane-based adhesive for improving adhesion is coated on one side of the circular knitted fabric, and an adhesive is partially coated and coated on one side of the knitted fabric for laminating under no tension using a gravure roller. The fabric is dried and heat-set while passing through a chamber at 80~120℃ and a tender at 180℃ at a speed of 30m/min so that it adheres to the knitted fabric stably when laminating a nano-membrane thin film with excellent ventilation. The knitted fabric is a knitted fabric composed of nylon fibers, and the coating agent for improving adhesion may use a polyurethane-based adhesive.
본 발명에서는 무장력하에서 접착력 향상용 코팅제를 편면코팅한 편직물의 코팅면에 이소시아네이트계 열가소성 접착제를 도포하여 핫멜트 접착제 패턴을 형성하는데, 다수의 원형 또는 타원형 도트를 형성하여 그위에 배치된 Nano-membrane 박막 필름의 박리강도를 향상시킨 투습방수환편물을 제공한다. In the present invention, a hot-melt adhesive pattern is formed by applying an isocyanate-based thermoplastic adhesive to the coated surface of a knitted fabric coated with a single-sided coating agent for improving adhesion under no tension, and a nano-membrane thin film formed thereon by forming a plurality of circular or elliptical dots It provides a moisture-permeable waterproof circular knitted fabric with improved peel strength.
본 발명의 기재인 편직물의 경우 직물보다 조직의 조밀성이 떨어지는 특성 때문에 그 위에 Nano-membrane 박막 필름을 접착하는 경우에는 일정한 접착성을 확보하기 어려운 문제가 발생할 수 있는데, 이러한 문제점을 해결하기 위해 다음과 같은 핫멜트 접착제 패턴을 형성하게 된다.In the case of the knitted fabric, which is the base material of the present invention, due to the characteristic of having less dense structure than the fabric, when a nano-membrane thin film is adhered thereon, it may be difficult to secure a certain adhesiveness. The same hot melt adhesive pattern is formed.
상기 핫멜트 접착제 패턴은 이소시아네이트계 열가소성 접착제로 이루어지고 각 도트의 지름이 0.6~0.7㎜이고, 도트의 총면적이 전체 환편물면적의 22~28%인 도트형 패턴의 고상 핫멜트 접착제 패턴인 것이 바람직한데, 지름이 0.6㎜미만인경우에는 접착제가 고르지 못한 편직물 표면의 움푹 들어간 부분으로 스며들기 때문에 일정한 접착력을 얻기 어려운 문제점이 있으며, 0.7㎜를 초과하는 경우에는 과다한 접착제 사용에 의한 편직물의 touch가 hard 해지는 문제점이 있다. 또한 도트의 총면적이 전체 환편물면적의 22%미만인 경우에는 편직물과 film의 결합력이 약해지는 문제점이 있으며, 28%를 초과하는 경우에는 투습력이 저하되는 문제점이 있다.The hot melt adhesive pattern is preferably made of an isocyanate-based thermoplastic adhesive, each dot has a diameter of 0.6 to 0.7 mm, and a dot-shaped solid hot melt adhesive pattern having a total area of 22 to 28% of the total circular knit area, If the diameter is less than 0.6mm, there is a problem that it is difficult to obtain a certain adhesive strength because the adhesive penetrates into the recessed part of the uneven knitted fabric surface, and if it exceeds 0.7mm, the problem that the touch of the knitted fabric becomes hard due to excessive use of adhesive. have. In addition, when the total area of the dots is less than 22% of the total circular knitted area, there is a problem that the bonding strength between the knitted fabric and the film is weakened, and when it exceeds 28%, there is a problem that the moisture permeability decreases.
이렇게 접착력 향상용 코팅제가 편면코팅된 편직물의 코팅면에 핫멜트 접착제 패턴이 형성된 편물을 Nano-membrane 박막 필름과 라미네이팅 하여 투습방수환편물을 제조하는데, 전처리된 편직물의 코팅면에 이소시아네이트계 열가소성 접착제를 도포하고 그위에 Nano-membrane 박막 필름을 배치하여 가열 및 가압함으로써 편물이 갖는 우수한 촉감 및 드레이프성은 그대로 유지하면서 Nano-membrane Film이 가지는 우수한 통기성을 유지하며 Nano-membrane 박막 필름과 편직물 원단의 접착성이 우수하여 투습방수환편물의 형태안정성과 접착강도를 개선해 준다.In this way, a knitted fabric with a hot-melt adhesive pattern formed on the coated surface of a knitted fabric coated with a single-sided coating agent for adhesion improvement is laminated with a nano-membrane thin film to produce a water-permeable and waterproof circular knitted fabric. An isocyanate-based thermoplastic adhesive is applied to the coated surface of the pretreated knitted fabric. By placing a nano-membrane thin film on it, heating and pressing it, it maintains the excellent touch and drape properties of the knitted fabric, while maintaining the excellent breathability of the nano-membrane film, and has excellent adhesion between the nano-membrane thin film and the knitted fabric. It improves the shape stability and adhesive strength of the moisture-permeable and waterproof circular knitted fabric.
