  Abstract

Polyamide6/polyurethane fabrics (PA6/PU) are the main materials for preparing various tents. To enhance the durability of PA6/PU fabrics exposed to sunlight for a long time, environmental-friendly, harmless to humans and low-cost CaCl2 is chosen as the surface modification agent to etch PA6 fabric during processing tent fabrics in the paper. The properties which are relative to the fabric durability are controlled by the complexation modification of PA6 fabric with CaCl2 ethanol solution. The results show that the roughness of PA6 fiber after CaCl2 modification is increased from 75.686 to 0.207 μm and the warp peeling strength of PA6-CaCl2/PU fabric comes to 5.8N which is 46.5% higher than that of original PA6/PU fabric. At the same time, the loss of tensile strength for PA6-CaCl2/PU fabric is less than that of PA6/PU fabric during heat aging process. On the other hand, Ca2+ presents an obvious effect on UV-C, while PU coating presents notable effect on UV-A and UV-B. The UPF value of prepared PA6-CaCl2/PU fabric increased to about 16 due to the PU coating and the fabric presents improved heat insulation when enduring sunlight irradiation. The durable PA6-CaCl2/PU fabric shows a promising application as tent fabric in textile industry.
