The invention discloses quick-moisture-conducting multifunctional composite spunlace nonwoven mask base cloth and a processing process thereof. The base cloth comprises upper, middle and lower layers,a porous PE film is arranged between the middle layer and the lower layer, the upper layer and the middle layer are compounded by spunlace and perforated to serve as quick moisture conducting layers,and the lower layer is honeysuckle fiber and xylitol fiber composite spunlace cloth serving as a bottom layer of the base cloth and is combined with the moisture conducting layers through hot air adhesion. The quick-moisture-conducting multifunctional composite spunlace nonwoven mask base cloth has advantages that by differential capillary effect of the moisture conducting layers, the nutrient solution absorbing rate is greatly increased, high liquid holdup and great moisturizing effects are achieved, antibacterial, heat clearing and detoxicating medical healthcare efficacies are achieved, and great beautifying effects are realized.
