  • 기존의 얇고 가벼운 기능성 투습방수 film은 각종 등산복이나 육해공군전투복, 경찰복, 소방복 등에 폭넓게 이용되고 있다. 그러나 현재의 이런 제품들은 뛰어난 투습방수성을 나타내지만 눈, 비, 이슬 등과 같은 수분과 만날 경우 필름 고분자 구조의 Swelling으로 표면의 불규칙한 요철현상이 생기며, 이는 제품의 불량으로 문제시 되고 있다. Swelling이 생기지 않는 친수성 Urethane film이 스키복으로 많이 상용되고 있기는 하지만 두께가 두껍고 무거워서 움직임이 불편한 단점이 있다. 본 연구에서는 이러한 문제점들을 보완하여 얇고 가벼운 기능성 비팽윤 투습 방수 필름을 제조하였다. 제조된 비팽윤 투습 방수 필름제품은 기존의 투습 방수 필름과도 다른 독특한 Bead concrete 구조를 형성하고 있으며, 미세입자들이 서로 접합하여 우수한 투습성을 발현하며, 기저층의 모노리스 멤브레인(Monolithic film)의 적층구조로서 형성되어 있어 강도 및 투습도 등의 성능이 제어되고, 수분 흡수에 따른 팽윤현상이 발생하지 않는다.

  • In this study, breathable waterproof materials were prepared by electrospinning. Five kinds of electrospun nanofiber web layered systems with different levels of nanofiber web density, as well as different substrates and layer structures were fabricated, and their mechanical properties (tensile, bending, shear, compression, surface, and thickness & weight) were measured by the KES-FB system and compared with those of conventional breathable waterproof fabrics (densely woven fabric, PTFE laminated fabric and PU coated fabric). The KES-FB measurements demonstrate that the lab-scale nanofiber web layered systems are more flexible and fuller than commercial nanofiber web layered systems, which have a more compact structure than the lab-scale nanofiber web layered systems. Densely woven fabrics and lab-scale nanofiber web layered systems showed lower values of tensile linearity (LT), bending stiffness (B), and shear stiffness (G) than those of PU coated and PTFE laminated fabric. These results indicate that they are more flexible and have less resistance to the shearing movement, corresponding to a more pliable material having a better drape, than PU coated fabrics and PTFE laminated fabrics.

  • Water vapour permeable and water resistant film was laminated to made footwear woven fabric and non-woven fabrics by screen type with thermosetting reactive hot melt adhesive. Optimum conditions of each process were investigated, and the properties of film laminated fabric with optimum conditions are evaluated. The results are as follows. Thermosetting reactive polyurethane hot melt is retain proper heat resistance differently thermoplastic hot melt. Optimum melting adhesive process conditions are as follows ; drum temperature $95^{\circ}C$, hose temperature $97^{\circ}C$, feeding pipe temperature $100^{\circ}C$, screen temperature $105^{\circ}C$, pressure of opposite roller $1kgf/cm^2$, pressure of laminating roller $3kgf/cm^2$, finishing speed 15 m/min, melting temperature $120^{\circ}C$, cooling time 20 s, pressing temperature $130^{\circ}C$, pressing time 30 s. As the thickness of film was increased, the water vapour permeability was decreased but water resistance was increased, and the effect of film is dominant over all the others in the air permeability.

  • Military textiles with breathable waterproof materials are expanding as form of winter clothes. Waterproof moisture-permeable clothes are very important for soldiers to survive in cold weather operations because they prevent loss of body heat from the penetration of water into the human body. Korea military uses the water resistance and moisture permeability to test the performance of waterproof moisture-permeable materials. Moisture permeability is measured according to the amount of evaporated water vapor passing through a fabric under specified temperature and humidity by using acetic acid potassium presented in KS K 0594. However, the test procedure for measuring the moisture permeability in the standard is presented only briefly and the preparation procedures for the test in accredited testing institutions are applied differently, leading to significant deviation of the results. This paper compares the procedures of testing institutions and examines the factors that affect moisture permeability. Finally, we propose a procedure to reduce the deviation of results and apply the proposed procedure in testing institutions. Our analysis results with one-way ANOVA under significant level (0.05) confirm that the deviation of results is reduced.

  • Changes of the properties of waterproof and moisture-permeable nylon fabric were investigated when softener, anti-static agents, anti-biosis agents were added to the polyurethane resin solution, and when they were applied after resin coating. The adding method of finishing agents into polyurethane layer resulted in an increase in water permeability but a severe decrease in peeling strength. It was found that the desired functionality such as softness, anti-staticity, anti-biosis were successfully introduced into waterproof and moisture-permeable nylon fabric by after-treatment of finishing agents.

  • This study investigated fabrics, washing and cares, design, pattern, subsidiary materials, and sewing methods with a focus on the functional outers using moisture-permeable waterproof fabric as a shell; in addition, each element was analyzed for differences depending on fabric type. The characteristics of 34 outers were investigated through labels, online product introductions, visual inspection, observations from two experts with more than 30 years experience and wear tests. Moisture-permeable waterproof fabrics used for the outer were classified into two types; in addition, the shell of the high-density fabric and the 2 & 3-layer fabrics had different characteristics. Various fabrics, detailed designs, and three-dimensional patterns suitable for each part of the human body were used to improve functionality. In addition, various subsidiary materials and sewing methods were used to form an organic relationship. The same washing and cares, patterns and subsidiary materials were used regardless of fabric type; however, the fabric type influenced the detailed design and sewing. The outers with high-density fabric had a loose fit, short placket, e-banded cuffs, lock-stitch, and lock-stitch+binding. However, the outer with 2 & 3 layer fabric had a slim fit, hood width adjustment, zippered pockets, cuffs with tab, seamless adhesive sewing such as laminating, lock-stitch+ seam-sealing, and welding.
