Abstract

In order to measure the allergen penetration of micropore fabrics, it is necessary to develop a convenient and appropriate experimental method for measuring a pore size of micropore fabrics. In this study, a simple and economical experimental apparatus was developed for the analysis of the pore size of micropore fabrics by measuring the weight reduction rate. In addition, the allergen blocking properties was evaluated by measuring the pore sizes of various fabrics. According to this study, the size of the pores of the microporous fabric could be obtained by measuring the weight reduction rates. In addition, higher weight reduction rate was obtained as the suction pressure passing through the particle permeation device decreased and the suction time was increased. It is expected that the developed experimental method and apparatus can be utilized as an experimental standard for quality control methods to verify the effectiveness of micropore fabrics used for house dust mite blocking bedding.

극세 공극 직물의 알레르겐 투과율을 측정하기 위해서는 극세 공극 직물의 공극을 측정하는 편리하고 적절한 실험 장치의 연구 개발이 필요하다. 본 연구에서는 중량 감소율을 측정하여 극세 공극 직물의 공극 크기를 측정하기 위한 간단하고 경제적인 실험 방범을 개발하였다. 또한, 개발된 미세 입자 투과 장치를 사용하여 다양한 직물의 공극 크기를 측정하여 알레르겐 차단 성능을 평가하였다. 본 연구에 의하면 극세 공극 직물의 공극의 크기는 중량 감소 비율을 측정함으로써 구할 수 있었다. 또한 중량 감소 비율의 값은 입자 투과 장치를 통과하는 흡입 압력이 작을수록, 흡입 시간이 길수록 큰 값을 나타났으며, 이 값으로부터 직선 삽입 방법을 통하여 실험 직물의 공극 크기를 측정 할 수 있었다. 개발된 실험 장치 및 방법은 집먼지 진드기 차단 침구에 사용되는 극세 공극 직물에 대하여 그 효과를 검증하는 품질 관리 방법의 실험 기준으로 사용될 수 있을 것으로 기대된다.
