Abstract: The basic performances of coffee carbon fibers were tested, such as surface morphology, strong stretching property and moisture regain. Coffee carbon fiber, cotton, viscose and modal fiber were selected as the materials and 8 fabrics in two series were woven according to different blending proportions. Fabric wearability was tested and analyzed. The results showed that many nanoscale coffee carbon particles are adhered on the lengthways surface of coffee carbon fibers, and the transverse sections of fibers have obvious cavity structure; the breaking strength, elongation at break and initial modulus of coffee carbon fiber are lower than ordinary polyester fibers, and the moisture regain is increased; the fabrics with 35% coffee carbon fiber and cotton, which the warmth retention property is better than the fabrics with 35% coffee carbon fiber and modal or viscose; the fabrics with 35% coffee carbon fiber and viscose or modal, which the wet comfort and anti-pilling property and drapability are better than the fabrics with 35% coffee carbon fiber and cotton; the fabrics with 35% coffee carbon fiber and modal or cotton, which the crease recovery ability is better than the fabrics with 35% coffee carbon fiber and viscose; the fabrics with 35% coffee carbon fiber and viscose, which the air permeability is better than the fabrics with 35% coffee carbon fiber and modal or cotton.
