The present invention relates to an air texture processing for bag fabric paper, while having the physical properties of the existing nylon fibers, and excellent color fastness and deep color resistance to disperse dyes during dyeing in the air texture processing fabric weaving high-quality handbag fabrics It is about.

In general, the outer shell of a bag including a handbag is made of natural leather or artificial leather, and is manufactured to store various objects therein. The natural leather and artificial leather products are discolored or faded by rain or the like after relatively short periods of time when the pattern is formed by color or printing having a color on the surface, and thus lowers the decorative effect of the product. The same decorative process is not being performed properly.

 Therefore, the handbags that can be seen around these days can only be treated as much as dyeing the same color of the leather as a whole, which has the disadvantage of degrading the product quality or changing various designs.

On the other hand, in the case of the world's luxury brand handbag fabrics that use jacquard fabrics, which have been recently adopted as a bag envelope, demands a high-quality bag fabric with excellent deep color and excellent fastness.

Korean Patent Application No. 1981-0001943 proposes a "manufacturing method of highly durable nylon fuji having a similar appearance and feel to cotton fabrics." And Korean Patent Application No. 1999-0049952, "Manufacture of lightweight heat-resistant polyamide-based fabrics. Method "is introduced. However, the proposed techniques only suggest polyamide based fabrics.

Nylon has a low initial modulus of elasticity, so it has a soft touch, high strength due to the characteristics of the yarn itself, and excellent abrasion resistance, but dyeing fastness when dyeing at high concentrations is performed due to dyeing with acid dyes. There is a problem, and in particular, due to the limitation of expressiveness by printing, there was a problem that the color expression power required for high-quality handbags is insufficient.

Therefore, in the present invention, while having the physical properties of nylon fibers, such as the existing touch and durability, it has a fine loop and excellent strength and excellent uniformity, as well as excellent color fastness and deep color resistance to disperse dyes when weaving and dyeing fabrics. It is a technical task to provide high-quality handbag fabrics capable of expressing city luxury colors.

Therefore, according to the present invention, the polyethylene terephthalate / polytrimethylene terephthalate side-by-side composite spinning filament yarn is supplied to the air texturing apparatus through the first feed roller, and the high-strength polyethylene terephthalate filament yarn is screened by the effect yarn. After supplying together with the air texturing device through a feed roller to interrogate the screening with the effector in the air texturing device, passing through the third feed roller and the heater, passing through the feed roller, the high-colored bag fabric, characterized in that the winding There is provided a method of manufacturing a ground air texture.

In order to provide a high-fidelity bag textile paper air texture processing of the present invention, the first feed yarn of polyethylene terephthalate / polytrimethylene terephthalate side by-side composite yarn filament yarn as the effect yarn (1) as shown in FIG. It is supplied to the air texturing apparatus 5 through the roller 3, and the high-strength polyethylene terephthalate filament yarn is fed together to the air texturing apparatus 5 through the second feed roller 4 by the screening (2). After interweaving the screening effect with the effect yarn in the ring apparatus, the third feed roller 6 and the heater 7 are passed through, the feeding roller 8 is passed through, and wound up by the winding roller 9.

In the present invention, the polyethylene terephthalate / polytrimethylene terephthalate side-by-side composite spun filament yarn having the strength of 3.8 ~ 4.2g / d, 30 ~ 32% elongation, 10 ~ 14% non-shrinkage rate is a fine loop The excellent high strength polyethylene terephthalate filament yarn, which has the strength of 5.0-5.5 g / d, 16-22% elongation, and 2.0-3.5% non-shrinkage ratio, has excellent strength and homogenization of crimp. Can be excellent. In addition, it is possible to express a luxury color when printing with excellent color fastness and deep color for disperse dyes during dyeing after weaving the fabric in harmony with the effect yarn and screening.

The effector is supplied to the air texturing device through the first feed roller, and the screening is supplied together to the air texturing device through the second feed roller to entangle the screening with the effector in the air texturing device. The effector is wound around the outer diameter of the air texture yarn.

In particular, in the present invention, it is important to adjust the overfeed rate before the interweaving of the effector and the examination so that the effector covers the examination uniformly. The overfeed rate given to the effector between the first feed roller and the air texturing device is 0.25. It is -0.30 and it is preferable that the overfeed rate given to the examination between a 2nd feed roller and an air texturing apparatus is 0.10-0.15.

The air pressure in the air texturing device is 10 ~ 12bar is good for the uniform examination cover of the effect yarn, the heater temperature is preferably 180 ~ 200 ℃ in terms of heat setting of the effect yarn. The air texturing yarn made in this way has a higher level of homogenization, but if the air pressure is too high, it is difficult to form a micro loop of the composite yarn filament used as an effect yarn. Therefore, it is necessary to set the above air pressure for optimal loop formation. .

The high-textured bag textile paper air texture processing provided by the present invention is an effect yarn polyethylene terephthalate / polytrimethylene terephthalate side-by-side composite yarn filament yarn and the high-strength polyethylene terephthalate filament yarn screening and air strength and 4.8 ~ 5.0 g / d, elongation 16 ~ 20%, uniformity (U%) 2.01 ~ 2.30%, crimp bacterium (10m%) are provided as 0.30 ~ 0.44. Not only is a microloop formed, but also has a property of expressing a smooth texture while wrapping the screen with shrinkage of the effect yarn by the heat of processing during salt processing.
