Abstract

The invention discloses a method with steady production process for producing a composite combined filament yarn with steady quality. The method comprises the steps of: fusing dry slices of a PTT (Polytrimethylene Terephthalate) material accounting for 60%-90% of the total weight to form a spinning PTT material melt; fusing dry slices of a PA6 (polyamide 6) material accounting for10%-40% of the total weight to form a spinning PA6 material melt; extruding the PTT material melt and the PA6 material melt after passing through respective spinning melt channels by an eight-shaped spinning component; then cooling, oiling and forming the composite combined filament yarn after the melt passes through a spinning channel, a pre-networking device and a hot roller drawing device; then enabling the composite combined filament yarn to pass through an NaOH solution with a percentage by weight of 0.5-10% in a boiling water state; and thereby separating the composite combined filament yarn into the combined filament yarns for spinning. According to the composite combined filament yarn and the method for producing the combined filament yarn for spinning by utilizing the composite combined filament yarn, disclosed by the invention, the production process of the combined filament yarn is simplified, and output and quality of the combined filament yarn are improved greatly.

Description

technical field [0001] The invention relates to a compound mixed fiber yarn and a method for manufacturing the mixed fiber yarn for textile by using the composite mixed fiber yarn. Background technique [0002] For example, the patent specification of application number: 200510039169.9 discloses a polyester-based mixed fiber yarn, which is ejected from cationic dyeable polyester and polyethylene terephthalate through different spinneret holes of the same spinneret. coiled. It must be affected by the different drawing and processing properties of two groups of separate fibers during spinning, and the production in the spinning process is unstable and the production speed is low. [0003] For example, the patent No.: 00803097.9 discloses a method for manufacturing polyester-based mixed fiber yarns. After the same polymer is extruded in the same component, the tow is divided into two strands, and one of the tows is in the fiber-opened state. And carry out non-contact heat tre...
