Abstract: Abstract In order to explore the ideal apparel fabrics for down jackets and cold resistance clothes that can be used in extremely cold environment and the changes of hand with the temperature decreased. The bending and shearing performances of two types of fabrics are studied by the in-house made test device at 20℃,-5℃,-15℃,-25℃respectively. The structure parameters of the PTT fabric and Nylon fabric are similar. The results show that the hand of the two types of fabrics become more stiff with the temperature decreased. However, Nylon fabric becomes much stiffer than PTT fabric at the same temperature.

Key words: PTT fabric , nylon fabric , cold environmental condition , hand feeling , bending property , shearing property
