Embodiment 1
[0038] Embodiment 1: Spinning recycled cotton / polyester filament composite yarn
[0039] Adopt the biaxial system yarn spreader for filament beam splitting of the present invention, carry out splitting and spreading into two silk nets according to the above-mentioned splitting and spreading method of polyester filament bundle, and then separate with two silk nets at the nip of the front roller The bundles are recycled with cotton fiber strands for twisting and compounding to form a smooth composite yarn. The specific process parameters are shown in the table below. The spun polyester filament is split into a smooth composite yarn wrapped with recycled noil short fiber strands. The hairiness index, twist angle, breaking strength, elongation at break and yarn fineness of the yarn are not uniform. Rates are listed in the table below. Among them, the spinning rate is very high, which means that there is very little loss of fiber such as flying flowers, shavings, and broken ends; ...
Embodiment 2
[0040] Embodiment 2: Spinning soil seed wool / nylon filament composite yarn
[0041] Adopt the biaxial system yarn spreader for filament beam splitting of the present invention, carry out splitting and spreading yarn into two silk nets according to the splitting and spreading method of nylon filament bundle, and then separate with two silk nets at the nip place of front roller The strands of soil-grown wool fibers are twisted and composited to form a smooth composite yarn. The specific process parameters are shown in the table below. The spun nylon filament split yarn is a smooth composite yarn wrapped with short fiber strands of soil species, and the hairiness index, twist angle, breaking strength, elongation at break and yarn fineness unevenness of the yarn See list below. Among them, the spinning rate is very high, which means that there is very little loss of fiber such as flying flowers, shavings, and broken ends; Low, indicating good spinnability and high processing eff...
Embodiment 3
[0042] Embodiment 3: Reuse cashmere / silk composite yarn
[0043] Adopt the two-axis silk spreader for filament beam splitting of the present invention, split and spread the silk into two silk nets according to the above-mentioned splitting and spreading method, and then return to the two bundles respectively at the front roller nip. Cashmere fiber strands are used for twisting and compounding to form a smooth composite yarn. The specific process parameters are shown in the table below. The spun silk split yarn is wrapped with cashmere staple fiber and is wrapped with smooth and clean composite yarn. The hairiness index, twist angle, breaking strength, elongation at break and unevenness of sliver fineness of the yarn are as follows listed in the table. Among them, the spinning rate is very high, which means that the fiber loss such as flying flowers, crumbs, and broken ends is very small; the number of hairiness is also very small, which means that the smoothness of the yarn i...
