The invention discloses a one-step
dyeing method of cool
air layer bedding fabric. The method includes following processes: deoiling and washing grey cloth, preparing color paste, soaking and rollingfor three times respectively,
drying, baking, and obtaining a finished produce. Knitted water
ripple jacquard
air layer fabric is of a three-layer jacquard structure, surface filaments are 400D ultrahigh-molecular-weight
polyethylene filaments, bottom filaments are 200D
polyester filaments, 150D
polyester low stretch
yarn is arranged in the middle, jacquard weaving is water
ripple tartans, and thepolyester low stretch
yarn in the middles of the tartans generate concavo-convex sense, so that three-dimensional effect is realized. 400D ultrahigh-molecular-weight
polyethylene is adopted as the surface filaments, so that the fabric is high in heat
conductivity, low in
heat resistance, quick in heat conduction in summer and soft, smooth and cool in surface and is mainly used as cool bedspread fabric in summer. Ultrafine
coating color paste is adopted for rolling and
dyeing, so that
dyeing of ultrahigh molecular-weight
polyethylene filaments on the front and
polyester fiber in the middle andon the back is completed through the one-
step method. The method is short in production process, simple in operation, low in cost, energy-saving, capable of lowering consumption, clean and environment-friendly.
