海藻纤维腈纶与粘胶纤维腈纶混纺织物吸湿发热性能研究OA

To develop lightweight fabric with moisture absorption and heat generation property,a series of blended yarns were spun by combining natural polysaccharide-based regenerated fibers seaweed fiber and viscose fiber with solid acrylic and bulked acrylic fibers.The blended yarns included viscose/bulked acrylic 50/50,viscose/solid acrylic 50/50,seaweed/bulked acrylic 10/90 and seaweed/solid acrylic 10/90,all with a linear density of 19.5 tex.These yarns were knitted into fabrics.The yarns and fabrics moisture absorption,heat generation,thermal insulation and comfort property were tested.The results showed that the moisture regain of the blended fabrics ranged from 6%to 8%,within 30 minutes,the maximum temperature increase was between 4.7℃and 5.8℃,with an average temperature increase of 2.6℃to 3.5℃.Among them,the seaweed/bulked acrylic 10/90 blended fabric exhibited a thermal resistance value of 0.206 5 m²·K/W,air permeability rate of 372 mm/s and moisture permeability rate of 40.3 g/(m²·h),demonstrating excellent thermal insulation and comfort properties.It is believed that the developed knitted fabrics exhibit significant moisture absorption and heat generation effects,with simple preparation method and provide new insights for enterprises in the development of thermal insulating knitted products.
