Sheath-core die conjugate yarn, knitting fabric, production manner of clothing product, and sheath-core die conjugate yarn

摘要

It possesses the elasticity which is superior, has sufficient strength, transparency is high, gives satisfactory feeling, has moderate failure unit power, the new conjugate yarn is offered. In addition, the clothing product which uses the knitting fabric and that kind of knitting fabric which are formed making use of that kind of conjugate yarn is offered. Furthermore, it possesses the elasticity which is superior, has sufficient strength, the manner where transparency is high, gives satisfactory feeling, has moderate failure unit power, produces the new conjugate yarn is offered. As for the sheath-core die conjugate yarn of this invention, being the sheath-core die conjugate yarn which possesses the core part which includes the polyurethane and the sheath part which includes elastomer, as for the said polyurethane, reacting with poly all and the diisocyanate, reacting with both ends isoshianeto basic prepolymer and poly all and the diisocyanate and the low-molecular quantitative diol which can, reacting with the both ends hydroxyl group prepolymer which can, it can, to be the double prepolymer die polyurethane, fineness 18 - 110dtex, weight proportion 95/5 of the core part/the sheath part - 60/40, the compound spinning doing under conditions of stretching magnification ratio 1.5 - 4.0 times, it can.
