High-Temperature Dyeing of Hollow Polyester Fiber Knit Fabric

This paper briefly introduces some common dyeing methods of polyester fiber fabric,and using orthogonal test to ensure the optimal high-temperature dyeing of hollow polyester fiber knit fabric: dye depth 2 %(o.w.f),bath ratio 1∶20,dyeing temperature 130 ℃,dyeing time 60 min,mass concentration of additive 1 g/L.The bursting strength,warmth retaining property and air-permeability of both dyed and non-dyed fabrics are tested,it finds that the dyed fabrics strength unchanged,warmth retaining property increased and air-permeability decreased slightly.
