In order to explain in detail to the extent that those skilled in the art can easily practice the technical idea of the present invention, the most preferred embodiments of the present invention will be described with reference to the accompanying drawings.

First, in adding reference numerals to components of each drawing, it should be noted that the same components have the same numerals as much as possible even if they are displayed on different drawings.

In addition, in describing the present invention, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description will be omitted.

Hereinafter, with reference to FIGS. 1 to 3, a method for manufacturing a muffler according to a first embodiment of the present invention will be described.

1 is a flow chart showing a muffler manufacturing method in time series according to a first embodiment of the present invention, and FIG. 2 is a flow chart showing in detail the fabric weaving step shown in FIG.

1 and 2, in the muffler manufacturing method (S100), first, a fabric is woven with spun yarn according to a preset width of the muffler (S110).

More specifically, yarns for weaving the fabric are selected (S111), and warp and weft yarns are selected and sequentially weaved with the selected yarn (S112).

In the first embodiment of the present invention, a fabric is woven with silk yarn having a thickness of 80/2 denier or 60/2 denier.

It is preferable that the warp yarn is a silk yarn of 60/2 denier and a density of 72 yarns/in, and the weft yarn is a silk yarn of 80/2 denier and 102 yarns/in.

This is because, if the number and thickness of warp yarns are smaller than the above-mentioned values, the restoring force of the fabric is reduced, and the desired size cannot be obtained because the fabric is torn or contracted severely during the raising process described later.

Here, the fabric may be woven in a double weave.

More specifically, the double weave is woven with two sets of warp yarns and two sets of weft yarns, and the fifth warp yarn is entangled between the two fabrics, so that the front and back colors of the fabric can be woven differently, and the aesthetics and warmth can be improved.

Thereafter, the fabric is softened. (S120)

More specifically, the softening treatment is a process for imparting flexibility to the fabric, and the softening agent is applied and proceeds, and acts to increase the electrical conductivity of the fabric, minimize static electricity, and reduce the stiffness of the fabric, and may form a coating layer on the fabric. .

Figure 3 is a flow chart showing the brushing step shown in Figure 1 in detail.

Thereafter, the fabric is brushed. (S130)

More specifically, when an appropriate amount of napping is formed on the surface of the fabric, it is possible to reduce pushing and improve warmth retention. shearing) proceeds sequentially.

In napping, a roll surrounded by needles on the outer circumferential surface rotates and scratches the surface of the fabric moving in one direction to create thin fibers on the surface of the fabric (S131).

Shearing can change the length of the thin fibers on the surface of the fabric by partially cutting off the length of the thin fibers that occur on the surface of the fabric as the napping progresses. Fibers can be cut. (S132)

Thereafter, contamination of the fabric is removed and OB processing is performed. (S140)

More specifically, OB (Open Blowing) processing is a very high-density cotton fabric, so-called "rabba" fabric, wound the fabric together in a cylinder, applies steam to the fabric for a certain period of time, and then unwinds the fabric from the cylinder. Pressing and matt effect can be obtained.

Thereafter, the fabric is heat treated. (S150)

More specifically, as a heat set process for stabilizing the shape of the muffler by heat treatment of the fabric, after wet heat treatment for shrinkage, heat set treatment is performed with dry heat to stabilize the shape of the fabric. The dry heat treatment temperature is 160 It is preferably ~180°C.

This is because when the treatment temperature exceeds 180 ° C., there is a risk of yellowing and damage of the yarn, and the tactile expression of the used spun yarn is also an obstacle, so that the entire fabric may become severely stiff and the tactile feeling may be poor.

In addition, when the treatment temperature is less than 160 ° C., it is difficult to proceed with the next processing step because the stability of the napped portion is incomplete.

As an example of heat treatment, a large amount of steam is supplied to the inside of the steamer to keep the inside of the steamer in a high temperature and high humidity atmosphere, and the fabric is put into the steamer to perform wet heat treatment, the temperature is treated at 90 ° C, and a tenter is used for heat setting Dry heat treatment may be performed at 180 ° C.

Thereafter, the fabric is preshrunk. (S160)

More specifically, preshrunk processing is a processing to prevent shrinkage when washing, drying, or exposure to heat as a dimensional stabilization process for fabrics. It can swell and contract to relax between fibers, reducing its size.

Therefore, shrinkage can be prevented by densely pushing the weft yarns and pressing them together through pre-shrinking.

As an example of pre-shrinking, a compression shrinkage method may be applied.

That is, the fabric can be stretched and relaxed by passing through a plurality of rollers, and the heated roller and the roller for forming tension in the fabric can be disposed on both sides of the heated roller, respectively.

In the first embodiment of the present invention, surgery may be formed on the fabric.

More specifically, the surgical forming process may be performed after the weaving process of the fabric, and first collects about 10 warp yarns on the woven fabric to form S twist (accidental), and then two yarns that form S twist again. By secondarily twisting with a Z twist (left edge) to balance the twist, surgery with a rich sense of volume and soft and beautiful characteristics can be formed.

Hereinafter, a method for manufacturing a muffler according to a second embodiment of the present invention will be described with reference to FIGS. 1 to 5 .

FIG. 4 is a flow chart showing a method for manufacturing a muffler according to a second embodiment of the present invention time-sequentially, and FIG. 5 is a flow chart showing the washing step shown in FIG. 4 in detail.

1 to 5, in the muffler manufacturing method (S200), first, a fabric is woven with spun yarn according to a predetermined width of the muffler (S110).

More specifically, yarns for weaving are selected (S111), and warp and weft yarns are selected and sequentially weaved (S112).

In the second embodiment of the present invention, 80/2 denier silk yarn and 40/2 denier viscose spun yarn are mixed in a ratio of 50:50 to create a fabric.

It is preferable that the warp yarn is a viscose spun yarn of 40/2 denier and a density of 72 yarns/in, and the weft yarn is a silk yarn of 80/2 denier and 102 yarns/in.

As in the first embodiment described above, the fabric may be woven in a double weave.

Then, the fabric is washed with water (S210).

More specifically, the fabric is washed by passing through the washing device, and a plurality of rollers are sequentially disposed inside the washing device so that the fabric can be moved, and the washing device presses the fabric moving along the rollers. Impurities are first separated from the fabric by spraying water (S211).

Washing water is accommodated inside the washing device and the fabric is immersed, and high-temperature steam or water is sprayed into the washing device to form a vortex in the washing water. More secure. (S212)

Then, the fabric immersed in the washing water is taken out and pressurized water is sprayed again to separate impurities from the fabric secondarily (S213), and further, the washed fabric is dried by spraying air (S214).

That is, the washing effect can be further enhanced by performing multiple water washings of the fabric through the high-pressure pressurized water and the washing water in which vortexes are formed.

Thereafter, as in the first embodiment described above, softening treatment (S120), brushing processing (S130), OB processing (S140), and heat treatment (S150) may be performed.

Also, in the second embodiment of the present invention, surgery may be formed on the fabric as in the first embodiment.

As described above, the muffler manufacturing method according to various embodiments of the present invention and the muffler manufactured through the method can obtain a touch of cashmere material by weaving a fabric using silk yarn or viscose yarn and forming naps on the surface of the fabric. It can lower the product cost.

In addition, by adjusting the thickness and density of the silk yarn or viscose yarn, it is possible to prevent the fabric from being damaged by tearing during the raising process.

As described above, the optimal embodiment has been disclosed in the drawings and specifications. Although specific terms have been used herein, they are only used for the purpose of describing the present invention and are not used to limit the scope of the present invention described in the claims. Therefore, those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
