Embodiment 1

[0035] Two viscose filament bobbins and one recycled noil fiber roving bobbin are used, and the three-axis composite spinning is carried out according to the above composite spinning method. The specific process parameters are shown in the table below. The spun viscose filament double filament clamps and reuses the smooth composite yarn of falling short fiber strands, and 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; Low, indicating good spinnability and high processing efficiency in yarn forming. During the spinning process, there is no obvious fiber loss and fly, and the ring and plate are clean, which proves the effectiveness of this clamping and protecting composite spinning.

Embodiment 2

[0037] Two silk filament bobbins and one wool roving bobbin are used, and the three-axis composite spinning is carried out according to the above composite spinning method. The specific process parameters are shown in the table below. The spun viscose and silk double filaments clamp the smooth and clean composite yarn of recycled wool short fiber strands, 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 efficiency in yarn forming. During the spinning process, there is no obvious fiber loss and fly, and the ring and plate are clean, which proves the effectiveness of this clamping and protecting composite spinning.

Embodiment 3

[0039] Two polyester filament bobbins and one polyester-cotton blended roving bobbin are used, and the three-axis composite spinning is carried out according to the above composite spinning method. The specific process parameters are shown in the table below. The spun viscose and polyester double filaments clamp the smooth composite yarn with short fiber strands, the yarn hairiness index, twist angle, breaking strength, elongation at break and sliver fineness unevenness are shown in the table below listed. 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 efficiency in yarn forming. During the spinning process, there is no obvious fiber loss and fly, and the ring and plate are clean, which proves the effectiveness of this clamping and protecting composite spinning.

Abstract

The invention relates to a smooth composite spinning mechanism, method and application of a short fiber whisker strip clamped by double filaments via unequal tension. The mechanism is composed of a tension disk used for locating a tension filament and controlling tension thereof, a yarn guide hook used for locating a low-tension filament and a holding roller used for keeping the tension. The composite spinning method comprises the steps of: synchronously feeding the tension filament, the low-tension filament as well as the short fiber whisker strip into a front roller to enable the short fiber whisker strip to be wrapped by the two filaments in a traction zone; and forming a three-shafting spinning yarn with the short fiber whisker strip covered by the tension filament from the upside and support by the low-tension filament from the downside, wherein the composite yarn is a smooth composite yarn which is formed by spirally twisting the tension filament and the short fiber whisker strip and externally coating the low-tension filament. The mechanism is light, practical, convenient to install, controllable and adjustable, can produce yarns with steady structure and is suitable for composite spinning of high-count smooth yarns and superfine yarns of short fibers.

Description

technical field [0001] The invention relates to a compound spinning device and method for smooth yarn of short fiber strands clamped by double filaments with unequal tension in the field of ring spinning. Background technique [0002] With the increase of human demand and population, the scarcity of fiber resources and current energy, it becomes necessary to use the existing fiber resources efficiently, low consumption, ecology and recycling. Fiber is a kind of resource. A large amount of short fibers will be produced in textile processing, and a large amount of fiber materials will be discarded in textiles after human use. The reason is that these fibers are relatively short and weak. Traditional spinning cannot solve the recycling of such fibers, let alone high-efficiency, low-consumption, high-quality, ultra-fine spinning. [0003] Both natural fibers and chemical fibers have their own advantages and disadvantages. It is difficult for a single type of fiber and a single ...
