In this study, we evaluated warmth retention ability of polyurethane foam (non-laminated and laminated) plying with fabrics. The warmth retention ratio, measured by KES-F7, was used for expressing the thermal property of plied samples. Experimental results revealed that the warmth retention ratio of samples that were plied with fabrics were higher than the foams in plain (i.e. without plying with fabric). For non-laminated foams, the fabrics had generally increased the warmth retention ratio by 10%. For laminated foams, the increase was about 4 to 5% in the warm retention ratio. By comparing the warmth retention ratio between the non-laminated foams and laminated foams, laminated foams have higher heat retention power. Being a close-to-skin garment, the air permeability is an important factor to determine their usage. Thus, we examined the air permeability of the different samples and the results were discussed properly.
The wetting time of fabric-foam-fabric plied materials was measured in this study. The fabric-foam-fabric plied materials were prepared by plying polyurethane foams (non-laminated and laminated) with different fabrics. The plied material would be proposed for making intimate apparel which is a kind of close-to-skin garment. Thus, the wetting ability of the material would affect the comfort behaviour. Therefore, we reported the wetting time values of different plied samples and the results were discussed properly.
During sweating, textile materials would absorption water and then spread. The liquid spreading speed in the textile material would affect the comfort property. In this study, the liquid spreading speed of fabric-foam-fabric plied materials were studied. The plied material is intended to be used in close-to-skin garment such as intimate apparel. Thus, the liquid spreading speed of the material would affect its comfort property. The fabric-foam-fabric plied materials were prepared by plying polyurethane foams (non-laminated and laminated) with different fabrics. Therefore, we reported the liquid spreading speed values of different plied samples and the results were discussed properly.
Moisture management is an important behaviour during engineering of textile material. In case of intimate apparel (which is in close contact with skin), its moisture management property would affect the comfort behaviour during use. Fabric-foam-fabric plied materials are commonly used materials for making intimate apparel. In this study, we prepared different fabric-foam-fabric plied materials by plying polyurethane foams (non-laminated and laminated) with different fabrics. Their performance on absorption rate, accumulative one-way transport capability and spreading speed had been measured objectively in previous works using instrument (moisture management tester) according to AATCC Test Method 195. Based on the data, we can calculate the overall moisture management capability (OMMC) of the piled materials. Therefore, we reported the OMMC values of different plied samples and the results were discussed properly.
Fabric-foam samples were prepared by plying polyurethane foams (non-laminated and laminated) with different fabrics in this study. The fabric-foam plied samples were intended to be used for intimate apparel which is a kind of close-to-skin garment. The comfort requirement of intimate apparel is highly concerned and smoothness, softness, stiffness and drape are the consideration factors. Therefore, we evaluated the mechanical properties of smoothness, softness, stiffness and drape of the different plied samples and the results were discussed properly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
