Problems solved by technology

[0005] The above-mentioned related methods, first of all, are spinning for the purpose of changing the yarn style, fancy or high-branching of fibers with excellent spinnability, and are powerless for fibers with poor spinnability or cannot be spun at all. ; Second, it is not suitable for high-branched or even ultra-high-branched spinning of short and weak fibers

Embodiment 1

[0041] The following specific examples 1-3 are for different fibers and their linear densities, i.e. selecting different filaments, different roving slivers and different composite ratios and different composite spinning process parameters, i.e. the tension of the filaments, the spreading rod Speed, spindle speed, front roller speed, spinning twist. Carry out the spinning of the smooth composite spinning mechanism and method of the composite filament spreader smooth composite spinning after the filaments of the present invention are opened and split, and the high count smooth composite yarns are spun. The selected short fibers are all ultra-short and weak fibers, which cannot be carried out by traditional spinning, and the kapok fiber is also easy to shed. Embodiment 1: Spinning recycled cotton / viscose filament composite yarn

[0042] Adopt the composite filament spreader of the present invention that is used for the upper and lower layers after the filaments are unfolded and...

Embodiment 2

[0043] Embodiment 2: spinning kapok / polyester filament composite yarn

[0044]Adopt the composite filament spreader of the present invention for the upper and lower layers to be developed again after the filaments are unfolded and split, the polyester filament bundle is split and spread into the upper cover and the lower support wire mesh according to the above-mentioned split yarn spreading method, and then Twisting and compounding with kapok at the nip of the front roller to form a smooth composite yarn. The specific process parameters are shown in the table below. The spun polyester split-spread yarn clamps the smooth composite yarn wrapped with kapok staple fibers. The hairiness index, twist angle, breaking strength, elongation at break and yarn fineness unevenness of the yarn are as follows listed in the table. 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, indicatin...

Embodiment 3

[0045] Example 3: recycled cashmere+10% down / silk composite yarn

[0046] Adopt the composite silk spreader of the present invention that is used for the upper and lower layers of the filament after the splitting and splitting, the silk is split and spread into the upper cover and the lower support screen according to the above-mentioned splitting and spreading method, and then the front roller The jaws are twisted and combined with recycled cashmere fiber strips mixed with 10% down to form a smooth and clean composite yarn. The specific process parameters are shown in the table below. The spun nylon filament is divided into split and spread yarns to clamp and wrap the smooth composite yarn wrapped with recycled cashmere staple fibers. The hairiness index, twist angle, breaking strength, breaking elongation and yarn fineness of the yarn are different. The uniform rate is listed in the table below. Among them, the spinning rate is very high, which means that there is very litt...

Abstract

The invention relates to a composite filament spreading device and method for re-spreading upper and lower layers of a spread and split filament and application thereof. The composite filament spreading device is composed of a locating filament guiding disk, a primary filament spreading device, a splitter, an upper filament spreading device, a lower yarn guiding hook, a lower filament spreading device and the like, and is mounted on a ring throstle through a fixed frame. The method for re-spreading the upper and lower layers of the spread and split filament comprises the steps of: enabling a single beam of filaments after being located and flattened by the locating filament guiding disk to enter into the primary filament spreading device to be spread symmetrically and splitting the filaments into two filament layers by the wing section shaped splitter; directly upwards feeding one filament layer into the upper filament spreading device to be re-spread to form an upper cover filament mesh to be output; and feeding the other filament layer which is downwards guided and centered by the lower yarn guiding hook without twisting into the lower yarn spreading device to be spread to form a lower support filament mesh to be output, thereby clamping and wrapping short fiber whisker strips. The composite filament spreading device is suitable for spinning of ultra-short, easy chips-dropping and easy flying-producing fiber and shorter and weaker fiber protective type soft, smooth, high-count and superfine-branch composite yarns.

Description

technical field [0001] The invention relates to a filament bundle splitting and spreading protective compound spinning device in the field of ring spinning, a method for using the device and an application of the device. Background technique [0002] With the rapid development of the textile industry, the application of filaments is becoming more and more extensive, especially in the utilization of short fibers. In the textile processing process, short and weak fibers such as noil and noil increase; the fibers obtained from recycled textiles also have a certain gap in length and strength compared with the original fibers; these short and weak fibers The fiber cannot be spun or the spun yarn has low strength and more hairiness. As a result, this type of short and weak fibers cannot be fully utilized. However, the composite yarn of filaments covering staple fibers can make up for this deficiency and improve the utilization rate of staple fibers. [0003] It is difficult for...
