Summary:The present invention relates to a manufacturing method for a loop type Velcro having elasticity using nylon fine denier fiber covering spandex yarn of 20 denier and a loop type Velcro manufactured by the same. The manufacturing method for a loop type Velcro having the elasticity using the nylon fine denier fiber covering spandex yarn of 20 denier comprises: a knitting step (S1) of knitting in a structure in which wrap and weft are knitted by applying polyester filament yarn as the wrap by a knitting device and knitting nylon fine denier fiber covering spandex yarn and nylon monofilament yarn by alternately inputting the nylon fine denier fiber covering spandex yarn and the nylon monofilament yarn; a hot water immersion step (S2) of shrinking the nylon fine denier fiber covering spandex yarn by immersing the knitted fabric in water having a temperature of 70-80°C, wherein a nylon monofilament yarn relatively protrudes in a loop shape; and a dehydrating and drying step (S3) of dehydrating and drying the fabric immersed. The manufacture of the loop type Velcro having the loop on one side is completed. Therefore, the manufactured loop type Velcro is used as an attachment type with a hook type Velcro, and thus the loop type Velcro is used in a minimum length or area based on elasticity thereof. 본 발명은 20데니어의 나일론 세섬 커버링 스판덱스 원사를 활용한 신축성이 있는 루프형 벨크로의 제조 방법 및 그 제조 방법으로 제조된 벨크로에 관한 것으로, 편성기에서 폴리에스테르 필라멘트 원사를 경사로 적용하고, 나일론 세섬 커버링 스판덱스 원사와 나일론 모노필라멘트 원사를 교차로 투입하면서 편성하여, 경사가 위사를 엮는 구조로 편성하는 편성 단계(S1); 편성한 원단을 온도 70∼80℃의 물에 침지하여, 나일론 세섬 커버링 스판덱스 원사가 수축하고, 상대적으로 나일론 모노필라멘트 원사가 루프 형태로 돌출하는 온수 침지 단계(S2); 침지한 원단을 탈수하고 건조하는 탈수 및 건조 단계(S3)으로 일면에 루프가 형성된 루프형 벨크로의 제조가 완료되어, 그 제조한 루프형 벨크로는 후크형 벨크로와 함께 부착용으로 사용되어, 신축성에 의해서 최소 길이나 면적으로 사용할 수 있는 것이다.
