Description
Technical Field
The invention relates to the technical field of fiber production, in particular to a production device and a production method of an optical ITY fiber.
Background
The FDY terylene product belongs to fully drawn fiber, can be directly used for subsequent weaving, and can produce various fabrics. And the POY fibers and FDY fibers are plied before package forming to produce ITY fibers. Because the contractibility of the POY fiber and the FDY fiber is different, the two fibers can generate unique style hand feeling after being folded, and the fabric can have excellent drapability, velvet feeling and crepe feeling by matching with downstream weaving and dyeing and finishing processes, and the added value of the product is greatly increased.
However, in the current production process, FDY and POY are produced respectively and then are stranded and compounded to form ITY fibers. As in the Chinese patent application: 2011102636380, the technical content is that the produced FDY and POY are fed by a feeding compression roller and a feeding tension control roller, and are drawn, folded and wound to form. The technical scheme is that a plurality of sets of equipment are matched to complete the production, so that the equipment investment for producing ITY fibers is large, and the production efficiency is relatively low.

In order to achieve the purpose, the production device of the optical ITY fiber comprises a spinning assembly, a cooling device and an oiling device, wherein part of the spinning assembly is used for producing FDY fibers, the other spinning assemblies are used for producing POY fibers, a pre-networking device is arranged below the spinning assembly for producing the FDY fibers, a first hot roller, a second hot roller, a third hot roller and a fourth hot roller are arranged below the pre-networking device, a first yarn guide disc and a second yarn guide disc are arranged below the spinning assembly for producing the POY fibers, and a main networking device and a winding mechanism are arranged below the space between the second yarn guide disc and the fourth hot roller.
The cooling device can be a side-blowing cooling mechanism or a circular-blowing cooling mechanism, and the oiling device can be used for oiling the oil nozzle and can also be used in other known oiling modes.
According to the technical scheme, the POY spinning device is transformed on the basis of original FDY production equipment, part of the spinning assembly is used for spinning POY, the first yarn guide disc and the second yarn guide disc are arranged below the spinning assembly for spinning POY, the running direction of POY fibers is changed through the two yarn guide discs, and therefore the POY fibers and the FDY fibers can be folded before entering a main network device, the POY fibers and the FDY fibers are stretched and shaped by four hot rollers in the FDY production process, and the POY spinning device can achieve the special style due to different shrinkage rates after folding.
A method for producing optical ITY fibers by adopting the device specifically comprises the following steps:
s1, spinning FDY nascent fibers by the spinning assembly, cooling the FDY nascent fibers by the cooling device, then feeding the cooled FDY nascent fibers into the oiling device, passing through the pre-networking device, bypassing the first hot roller and the second hot roller, and feeding the FDY nascent fibers into the third hot roller and the fourth hot roller;
s2, spinning POY (polyester pre-oriented yarn) as-spun fibers by a spinning assembly, cooling the POY as-spun fibers by a cooling device, feeding the POY as-spun fibers into an oiling device, and sequentially passing through a first godet and a second godet;
s3, stranding the FDY fibers output from the third hot roller and the fourth hot roller and the POY fibers output from the second yarn guide disc, then feeding the FDY fibers and the POY fibers into a main network device, and finally feeding the FDY fibers and the POY fibers into a winding mechanism for winding and forming to obtain the ITY fiber product with light.
As an optimization: the speed of the first godet is 3500-4500m/min, the speed of the second godet is 3510-4550m/min, and the speed of the second godet is 10-50m/min faster than that of the first godet.
The speeds of the first hot roller and the second hot roller are 1500-2000m/min, the speeds of the third hot roller and the fourth hot roller are 3800-4500m/min, the tows are wound on the first hot roller and the second hot roller for 2-10 circles, and the tows are wound on the third hot roller and the fourth hot roller for 2-10 circles.
The temperatures of the first hot roller and the second hot roller are 75-100 ℃, and the temperatures of the third hot roller and the fourth hot roller are 125-140 ℃.
The winding speed of the winding mechanism is 3800-.
The tension in the POY spinning process is reasonable and stable by controlling the speed difference between the first godet and the second godet, wherein the speed of the second godet is greater than that of the first godet, and the difference is 10-50 m/min.
When the FDY fiber passes through the first hot roller and the second hot roller, the FDY fiber is wound on the first hot roller and the second hot roller for 2-10 circles, preferably 5-8 circles, and the optimal scheme is 6.5 circles, so that the FDY fiber can be fully stretched, the filament bundle cannot slip on the first hot roller and the second hot roller, and the stability is high. The winding of the FDY fiber on the third hot roller and the fourth hot roller can be referred to the winding condition of the FDY fiber on the first hot roller and the second hot roller, and the winding number can be adjusted finely.
The production device and the production method of the bright ITY fiber are improved by depending on the original FDY equipment and are used for producing the bright ITY fiber, namely a folded product of POY fiber and FDY fiber, because the two fibers have different shrinkages, the two fibers can generate unique style hand feeling after being folded, and the fabric can have excellent drapability, velvet feeling and crepe feeling by matching with downstream weaving and dyeing and finishing processes. The production method is suitable for market variation, is not subject to ink conservation and regulation, flexibly and flexibly utilizes the equipment platform, produces the variety required by the customer, and greatly improves the competitive power and the profitability of enterprises.
