Abstract

The invention discloses pre-oriented polyester yarns and a preparation method thereof and polyester fiber fabrics and a preparation method thereof. Cross sections of the pre-oriented polyester yarns are in shapes of split orange slices, and the pre-oriented polyester yarns are formed by combining fibers with *-shaped cross sections and fibers with orange-slice-shaped cross sections. The fibers with the *-shaped cross sections are prepared from semi-dull polyester and antibacterial masterbatches by the mass ratio of 1 to 0. 02-0.1. The fibers with the orange-slice-shaped cross sections are prepared from water-soluble polyester, wherein the water-soluble polyester accounts for, by mass, 25-75% of the mass sum of the water-soluble polyester and the semi-dull polyester. The pre-oriented polyester yarns are produced into high stretch polyester yarns through elasticity enhancing treatment, the high-profile-degree polyester fiber fabrics with *-shaped cross sections can be obtained through splitting treatment, and further multifunctional polyester fiber fabrics are obtained through silver plating treatment. The multifunctional polyester fiber fabrics have good antibacterial properties, superior radiation resistance performance, good moisture absorption and sweat releasing functions and high fiber cross section profile degree.

Description
