Hereinafter, the technical structure of the present invention will be described in detail with reference to preferred embodiments shown in the accompanying drawings.

However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Like reference numerals designate like elements throughout the specification.

1 is a flow chart of a fabric manufacturing method comprising a flame retardant yarn and a low fusion yarn according to a first embodiment of the present invention.

Referring to Figure 1, the fabric manufacturing method comprising a flame retardant yarn and a low fusion yarn, first to prepare a mixed yarn using a flame retardant yarn and a low fusion yarn (S100), and then prepare a general yarn and the mixed yarn (S200) By using the dual weaving method to prepare a fabric fabric (S300). Thereafter, the fabric is heat-treated (S400) consists of a process of fusion of low-fusion yarns.

The flame retardant yarn is not particularly limited as long as it is a fiber of a material that does not easily burn or burn, and various fibers may be used, and the low-melting yarn has a low melting point compared to the flame retardant yarn and the general yarn, and when the flame retardant yarn and the general yarn are melted It is not particularly limited as long as the fiber is fused to various fibers can be used.

The general yarn is a fiber mainly constituting the fabric, and may be a fiber mixed with natural fiber, synthetic fiber, or natural fiber and synthetic fiber.

The double woven weaving method is a weaving method for weaving the fibers and the back surface of the fabric so that the weaving is different, and thus a detailed description of the method will be omitted.

The heat treatment process is a process of melting only the low-melting yarn having a lower melting point than the ordinary yarn and the flame retardant yarn by heat, and is performed at a temperature between the melting point of the general yarn and the flame retardant yarn and the melting point of the low-fused yarn. That is, it is performed between the temperature below the melting point of the ordinary yarn and the flame retardant yarn and the temperature above the melting point of the low-melting yarn. Therefore, only the low fused yarn is melted through the heat treatment to form a structure fused to the general yarn and the flame retardant yarn.

On the other hand, the test results of the process according to the invention, the heat treatment process is preferably carried out at a temperature of 150 to 200 ℃, among them found that the optimal heat treatment process is performed at approximately 190 ℃.

2 is a schematic cross-sectional view of a woven fabric using the double weave method.

Referring to FIG. 2, a double-weaving method produces a fabric formed of a mixed yarn including a first yarn 102 of general yarns and a second yarn 104 of flame retardant yarns and low fusion yarns. When processing the fabric to produce a variety of products, the first layer 102 where the general yarn is located is a surface yarn layer (the layer of the outward side of the product), the second layer where the blended yarn is located ( 104 is formed of a backside yarn layer (the layer on the opposite side of the surface yarn layer). That is, the layer in which the ordinary yarn is located is exposed to the outside of the product.

Figure 3 shows a schematic view of a woven fabric using a blended yarn in the general yarn, weft yarn on the warp.

Referring to Figure 3 together with Figure 2, weaving the fabric using a blended yarn 120, including the general yarn 110 in the warp yarn, flame retardant yarn and low fusion yarn in the weft yarn, the detailed structure is not shown in the figure Using a weft double weaving method, the surface yarn layer is mainly exposed to the general yarn (110), the backside yarn layer is mainly woven so that the mixed yarn (120).

4 is a schematic diagram of a structure for manufacturing a blended yarn by the air texture (Air texture) method.

Referring to FIG. 4, the flame retardant yarn 122 is positioned at the central portion of the mixed yarn 120, and the low fusion yarn 124 is positioned to surround the outer portion of the flame retardant yarn 122. The mixed yarn 120 is manufactured using an ATY (Air textured yarn) processing apparatus, using a flame retardant yarn 122 as a core yarn, and using a low-melting yarn 124 as an effect yarn to the pressure of the air Use a method of mixing by tapping continuously.

On the other hand, the method of mixing the flame retardant yarn and the low fusion yarn may be used in addition to the air texture (Air texture) method, a variety of methods, for example, the interlacing (Interracing) method of pulling the yarn and the thread under the pressure of air Various methods can be used without being limited, such as a joint method of twisting a thread and manufacturing.

In Table 1, the division item means the sample name, and the same material was used for the warp yarn as the general yarn. In the weft item, the composition of the core yarn (C) and the effect yarn (E) is specified. For example, 'C: flame retardant 100/36 * 3P' has three thicknesses of flame retardant yarns having 100 thicknesses and 36 strands. It means that the core used. In addition, 'e: LMP75 / 24 * 3p' means that three low-fusion yarns having a thickness of 75 and 24 strands were used as effect yarns.

In addition, bark strength means the strength of tearing by pulling after sewing on the fabric, and bark fatigue means the degree of sewing holes stretched when pulling the fabric, and bow decay strength means that the thread of the fabric is pulled. When the thread is about the strength of falling out. Therefore, the higher the bark strength and the derailment strength, the higher the strength of the fabric, and the lower the bark fatigue, the higher the strength of the fabric.

Referring to Table 1, it was confirmed that all of the test items of bark strength, bark fatigue, and bow decay strength exhibited strengths above a predetermined standard. In addition, it was confirmed that by properly adjusting the ratio of flame retardant yarn and low fused yarn to the fabric, it is possible to manufacture a fabric having further improved strength of necessary items.

In addition, it was confirmed that all three samples had sufficient flame retardancy through the flame retardancy test. 'SE' in Table 1 indicates that combustion is stopped at a position of 50 mm or less from the ignition point when the fabric is lit in accordance with the US flame retardant material standard, that is, the test method of FMVSS 302, or combustion is performed within 60 seconds from the ignition time. It means it has been stopped.
