The mixed yarn comprises a composite fiber(A) of an extracting type and a common synthetic fiber(B) that is one with fibrous component of the composite fiber. The fiber A has a fineness of ultra-fine fiber owning a distribution of 0.04-0.7 denier and the occupational area of ultra-fine fiber of 60-90 % against the total cross-section area. The mixed ratio of A and B fiber expressed by the fineness is in the range of 1:1-4:1, and the following condition is required : Abws(the boil shrinkage ratio of A fiber)=7-9 %, Bbws(the boil shrinkage ratio of B fiber)=7-12 %, Afhs(the dry shrinkage ratio of A fiber)=15-20 %, Bfhs(the dry shrinkage ratio of A fiber)=15-20 %, The mixed yarn is produced by a feed rate of the following condition, (Abws+Afhs)=G1.35= Af= (Abws+Afhs), (Bbws+Bfhs)=G0.95= Bf= (Bbws+Bfhs), where Af is a feed rate of A fiber(%) and Bf is a feed rate of A fiber(%).
