Title:
CORE-SHEATH STRUCTURE YARN AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH0813272
Kind Code:
A
Abstract:

PURPOSE: To produce a core-sheath yarn for raised fabric having excellent mottled appearance and raising property by preparing an interlocked core-sheath yarn composed of polyester multifilament yarns having different dyeability and different boiling water shrinkage and subjecting the yarn to a turbulent fluid treatment to get the loop number falling within a specific range.

CONSTITUTION: This core-sheath structure yarn for raised fabric having excellent mottled appearance, raising property, touch and fastness is an interlocked core- sheath yarn composed of ≥3 polyester multifilament yarns consisting of two kinds of filaments having different dyeability. The sheath yarn is composed of a sea-island conjugate yarn A (composed of common polyester and an alkali- soluble polyester) and a filament yarn B (cation-dyeable polyester) having dyeability different from that of the island component of the conjugate yarn A and the core yarn is composed of the conjugate yarn A or a filament yarn other than the yarn A and having a boiling water shrinkage larger than that of the sheath yarn by ≥3%. The number of loops (X) of the yarn A having a loop height of ≥0.1mm after boiling water shrinkage at 98°C for 20min and that of the loops (Y) of the yarn B satisfy the formula X:Y=1:5 to 5:1.
