Description
Technical Field
The invention relates to the technical field of polyester fiber manufacturing, in particular to a processing system and a processing method of polyester ITY composite yarns.
Background
With the further increase of the production energy of the Chinese chemical fiber polyester fiber, the differentiation and functionalization of the polyester fiber product increasingly become the focus of people's attention, and the improvement of the product differentiation rate can improve the technical content of the fiber on one hand, and can meet the quality requirements of high-end markets and customers on the other hand, so that the polyester fiber product is used for developing various garment materials with high added values. The polyester ITY is short for polyester mixed filament yarn, and particularly relates to an ITY composite yarn which is produced by simultaneously producing FDY and POY yarns by adopting two-step mixed fiber equipment or one-step spinning equipment in the production and manufacturing process and finally combining and mixing the fibers through a network device.
However, the current production processes are totally three, specifically as follows:
1. the conventional FDY and POY yarns are combined and mixed in a network device by other grid-connected or fiber-mixed equipment in a two-step method to produce the ITY combined yarn, and the method has high production cost and is gradually replaced by a one-step ITY combined yarn production process.
2. FDY yarns and POY yarns are adopted for simultaneous production, the FDY yarns are stretched through a first group of hot rollers GR1, the POY yarns are not shaped through a second group of hot rollers GR2, and the FDY yarns are directly combined and mixed in a fiber mode from a main network device, wherein the shrinkage of the FDY yarns is controlled through a shaping hot roller GR2, and the shrinkage of the POY yarns cannot be controlled through shaping, so that the ITY composite yarns with specific differential shrinkage are formed.
3. FDY and POY are simultaneously produced, the FDY is stretched through a first group of hot rollers GR1, the POY is shaped through a second group of hot rollers GR2, and the FDY and POY are combined and mixed with the FDY from a main network device, and the shrinkage of the FDY and POY is controlled through a shaping hot roller GR2 because the FDY and POY fibers have different shrinkages, so that the shrinkage of the FDY and POY in boiling water is simultaneously improved or simultaneously reduced, the yarn bundle generates a fluffy feeling, and the ITY composite yarn with different hand feelings and fluffy feelings is produced.
At present, in the production process of ITY yarns, the boiling water shrinkage rate of FDY yarns can be controlled to be 5-12% and the boiling water shrinkage rate of POY yarns can be controlled to be 15-65% under the condition of a setting temperature of 80-100 ℃. In the three production process modes, after the ITY combined yarn is easily woven into the fabric, the shrinkage rate of the FDY yarn on the surface of the yarn bundle is far smaller than that of the POY yarn, after the fabric is dyed and shaped at 80-100 ℃ and shrunk, the FDY yarn protrudes out of the surface, so that white stripes, referred to as white exposure, are formed on the surface of the fabric, and the style and the quality of the fabric are influenced by the white exposure. In order to make the filament bundle or the cloth cover form the effect of POY winding FDY after weaving, dyeing and finishing and shrinking the ITY combined filament yarn, the shrinkage rate of the POY is required to be smaller than that of the FDY, and obviously, the production methods cannot realize the purpose.
