The invention relates the moisture absorption and perspiration blended yarn and preparing method. The yard adopts the fibres possessing different colors and 40%-100% moisture absorption and perspiration fibre. The method uses the ECDP which possesses the honeycomb pore structure as moisture absorption and perspiration fibre, and utilizes the capillary effect to strengthen the effect of moisture absorption and perspiration. Due to adopt cation dye, the yarn possesses the advantages of wide color spectrum, bright color and convenience dyeing, and suits for multi-item-small-lot production. Besides, the energy consumption with the said fiber to dye is lower than the one with the convention moisture absorption and perspiration polyester. The fabrics made with the said yarn possess the good shaped fastness and sublimation fastness. |
