Effect of Yarn Characteristics on Bagging Recovery and Comfort Properties of Warp-Knitted Fabric for Sport and Recreation

Abstract

To investigate the bagging recovery performance of sports and recreation, three types of warp-knitted fabric were produced with polyethylene terephthalate (PET) fiber, Coolmax® fiber, elastic fibers polybutylene terephthalate (PBT) fiber, and Sorona® fiber as raw materials, with a locknit. And their bagging recovery performance was studied. Their moisture management performance, breaking strength, wear resistance, and air permeability were also evaluated. Results indicated that the bagging recovery rate was positively correlated with the elastic recovery rate of the fabric. Elastic fabric recovery decreased as fixed elongation length increased while residual rates increased as fixed bagging height increased, when the fixed elongation length was from 30 to 50%, the warp elastic recovery rate of the three types of warp-knitted fabric was reduced by about 10% and the weft was reduced by about 5%. When the bagging height was from 12 to 18 mm, the residual rate of fabric bagging 20 times increased from 22.5 to 40%. With an increase in the number of bagging, bagging work decreased indicating aggravated fatigue damage leading to reduced fabric recoverability. Fabrics containing Coolmax® had excellent moisture management performance, and each rating index had reached level 4 and above, integrated fabric bagging recovery ability and moisture management ability, fabric warp kitted by Coolmax® and Sorona® was more suitable for use in warp-knitted fabric for sport and recreation.
