The invention offers a different contraction blending fiber useful for grey yarn of textile and knitting, whose effective element is superfine multifilament, and inside is a potentially high contraction multifilament, having good sense of touch. Being single yarn fineness 0.5 denier or less, using polyamide, polyester, and so on, and a mixture of polyester and terephthalic acid as an outer part, different contraction blending fiber produces with the inside fiber a potentially high contraction fiber.
