Chemical fiber texturing and air yarn covering all-in-one machine

Abstract

The invention relates to a chemical fiber texturing and air yarn covering all-in-one machine which comprises a raw filament support device (1), a filament penetrating device (2), a hotbox device (3), a cooling device (4) and a false-twist device (5). The all-in-one machine is characterized in that a spandex unwinding device (6), a spandex drawing roller (7), a covered yarn feed roller (8) and a parallel stranding roller (9) are arranged under the false-twist device (5). The all-in-one machine is quick in machining speed and high in mechanical efficiency, the yarn can be covered on the chemical fiber filament and the spandex at the same time, and the technical disadvantages that the existing air covering machine is slow in machining speed and only can cover the yarn on the chemical fiber filament and the spandex by two equipment can be overcome, and according to a novel chemical fiber texturing and air yarn covering structure, the spandex filament does not need excessive filament guiders, the spandex filament can be directly stranded with the chinlon filament or the dacron filament to avoid broken end caused by the friction between the spandex filament and the ceramic, and the quality of the mechanical product can be improved at the same time.

Description

technical field [0001] The invention relates to a chemical fiber textile machine, in particular to a machine capable of wrapping various fibers such as nylon yarn and spandex yarn, polyester yarn and spandex yarn, polyester yarn and nylon yarn under the condition of machine producing textured yarn at the same time. Chemical fiber texturing machine for yarn covering process. Background technique [0002] At present, to process the stretched covered yarn of nylon and spandex, polyester and spandex, it is necessary to press the nylon POY yarn according to the process of the nylon false-twist texturing machine. Cooling device, false twisting device and winding device are processed into nylon DTY yarn, and then nylon DTY yarn and spandex yarn are wrapped on air wrapping machine. Therefore, two kinds of equipment are required to complete nylon and spandex wrapping yarn. In addition, the air-coated yarn machine unwinds the nylon DTY yarn and wraps the spandex yarn, so the nylon DT...

Problems solved by technology

In addition, the air-covered yarn machine unwinds the nylon DTY silk cake and spandex yarn for covering and plying, the nylon DTY silk cake and the spandex silk cake will not be used up at the same time, and the small roll cannot be used any more, which will cause a lot of consumption

In addition, the existing air-wrapping machine will break ends during the covering and plying process. The higher the speed, the more broken ends, which will cause a lot of consumption. Therefore, the production speed of the air-wrapping machine can only be reduced to reduce broken ends and reduce consumption. , its normal processing speed is 350 meters to 450 meters per minute

Since the textured covered yarn needs two types of equipment to complete the processing, the loss of labor, packaging, materials, power and raw silk in the secondary production will increase a lot, resulting in a lot of waste, which does not meet the requirements of energy saving and environmental protection at all.

[0003] Currently on the market all-in-one texturing and covering yarn machines, the spandex unwinding device is installed on both sides of the first roller of the texturing machine in terms of structure, because the spandex silk path is too long and the corners are too many, the process route is unreasonable, so the spandex The strength requirements are too high, and the spandex must be specially spun, and the cost is also high. The higher the speed in high-speed production, the more broken ends, and the machine efficiency and cost cannot be fully utilized. Therefore, the exploration and research of various manufacturers , have not been able to improve and promote

[0004] Some devices use spandex rollers on the second rollers of the texturing machine, which makes the height of the machine too high and difficult to operate, and has to reduce a spandex roller. Post-process processing, the fabric is not stable, can not reach high quality, and can not meet the use of high-end fabrics
