The invention relates to silk weaving blending fabric. Binba yarns and real silk yarns are weaved by a circular knitting machine. The density PA of the fabric is not smaller than 80 vertical lines/5CM, and PB is not smaller than 65 transverse lines/5CM. According to the fabric provided by the invention, the moisture absorption characteristic of Binba yarns similar to cotton fibre is maintained, so that the fabric is strong in sweat absorption, and is always dry and comfortable, therefore, the deficiency that pure real silk products attached to the human body are bonded to skins during sweating is overcome, and meanwhile, the fabric combines the elasticity of Binba yarns and flexibility and smoothness of real silk, so that the fabric is comfortable to wear.
