Embodiment 1

[0026] Step 1: On the dual-zone three-roller drafting mechanism of the ring spinning frame, the wool roving sliver is fed from the bell mouth and drafted by the cradle drafting mechanism; the polyester filament is drawn from the front roller gripper Mouth feeding, merged with the drawn wool roving sliver;

[0027] Step 2: The polyester filament is conveyed by the front roller and fed into the twisting area of ​​the wool roving sliver. The filament is conveyed through a precision-made yarn guide device and aligned with the center of the wool roving sliver. After merging with the wool roving sliver , and enter into the twisting triangle area of ​​ring spinning together for twisting;

[0028] Step 3: Control the tension of the filament through the filament tension control device, and the filament tension value is 30cN; Carry out wool fiber coating twisting to filament for the first time, and the twist coefficient of its coating twisting is 260 respectively, twist direction S;

Abstract

The invention discloses a preparation method of wool fiber core spun yarn. Filaments are mainly taken as core yarn, wool fiber coating is performed on the surface of the core yarn twice, the twisting direction of wool fibers during the first coating is opposite to the twisting direction of the wool fibers during the second coating, the content of filament core yarn in the wool fiber core spun yarn produced through the method is 20%-35%, and the content of wool fibers is 65%-80%. According to the preparation method of the wool fiber core spun yarn, the filament is coated by the wool fibers twice and twisting directions of coating are opposite, so that sliding of the wool fibers on the surface of the filament core yarn is reduced or avoided, exposed filament core yarn on the surface of fabric is reduced, and the coating effect is good.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of wool fiber core-spun yarn. Background technique [0002] Core-spun yarn is generally a yarn made of synthetic fiber filaments with good strength and elasticity as the core yarn, and short fibers such as cotton, wool, and viscose fibers are twisted and spun together. The more common core-spun yarns include polyester-cotton core-spun yarn, which uses polyester filament as the core yarn and outsources cotton fibers; and spandex core-spun yarn, which uses spandex filament as the core yarn and outsources yarn made of other fibers. The disadvantage of these core-spun yarns is that the short fibers are covered only once outside the filament core yarn, and the short fibers in the yarn will slip on the filaments, causing the filaments to be exposed in some segments of the yarn, on the surface of the fabric. Defects occur and the coating effect is poor...
