Studies on Interlining -The change of the physical properties based on the weight polyethylene resin of the fusible interlining-

심지에 관한 연구(I) -접착심지의 polyethylene 수지량에 따른 물성변화-

This article aims to determine the interrelation among exfoliation strength, the repeated laundry number, the coefficient of friction and the cover factor about the fusible interlining produced by using different amount resin. The practicality of stiffness and warmth of the fusible interling were examined. The results are summarized as follows: 1) As a factor that affecting the exfoliation strength of fusible interlining, the coefficient of friction and the cover factor about the fusible interlining produced by using different amount resin. (2) Regardless of the weight of the resin, the exfoliation strength of fusible interlining declined gradually as the repeated laundry number increased. This tendency arises much more in the case of the filament yarn fabric than in that of the spun yarn fabric. The stability of the exfoliation strength was better, regardless of the increase of the repeated laundry number, when the weight of the weight of the resin was 10 g/$m^2$. (3) The spun yarn fabric, which has more fuzz than the filament yarn fabric, is more suitable for the fabric of fusible interlining. The smaller the cover factor difference between the face cloth and the interlining cloth, the stronger the exfoliation strength. (4) When the stability of the shape is a necessary factor in the consumption of the fusible interlining, a resin weight of 20 g/$m^2$ is the most suitable; however when stiffness and warmth are necessary factors, a resin weight of 10 g/$m^2$ is the most suitable.
