The Manufacture and Physical Properties of Hanji Composite Nonwovens Utilizing the Hydroentanglement Process

摘要

This study aims to develop the new Hanji paper composite nonwovens that positively affect the antimicrobial activity, deodorization, and comfort functionality of natural materials of cotton and rayon that have high consumer preference and to manufacture new sanitary goods and facial mask sheets utilizing the hydroentanglement process. The results of the study through the evaluation analysis of functionality and properties of the composite nonwovens developed in this study are as follows. The manufactured composite nonwovens have improved functionalities of absorption velocity, antimicrobial activity, and deodorization from the base materials of C45 (Cotton (45 g/m(2))) and R53 (Rayon/PET (53 g/m(2))). Also, physical properties such as tensile strength, breaking extension, and tearing strength have improved significantly. The texture of composite nonwovens of Mulberry 70 %/Pulp 30 %(15) of Hanji paper weight 15 g/m(2) with base material did not show a significant difference compared to the nonwovens of C45 and R53. However, the soft texture of composite nonwovens of Mulberry 70 %/Pulp 30 %(25) of Hanji paper weight 25 g/m(2) with base material showed somewhat of a decrease compared to the nonwovens of C45 and R53. When considering the marketability, the composite nonwovens of Mulberry 70 %/Pulp 30 %+C45 and Mulberry 70 %/Pulp 30 %+R53 were estimated to be a positive development for use in female sanitary products and facial mask sheet products. These newly developed Hanji composite nonwovens could contribute to the development of high value added products that would satisfy the consumers.
