Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-faced jacquard knitted fabric,

The present invention relates to a method for producing a double-sided jacquard knitted fabric according to the waxing condition of a human-friendly spinning yarn, and more particularly to a method for producing a double-side jacquard knitted fabric using polyethylene terephthalate and polypropylene to produce a spun yarn, .

Generally, due to economic growth and improvement of living standards of consumers, there is an increasing demand for functional apparel products having diverse functions, and a lyocell which has advantages of natural fibers and man-made fibers is developed and used. Lyocell is a type of regenerated cellulose fiber known as environmentally friendly fiber. It has a high dryness and wet strength compared to natural fiber, which is connected with maintaining a high degree of orientation in crystalline and amorphous regions long and thin in the fiber axis direction. It is widely used because of its many advantages such as hygroscopicity, durability and touch. However, it has a disadvantage that its surface is smooth and the bonding force between yarns is weak.

On the other hand, polyester fibers are widely used for clothing and industrial applications due to their excellent mechanical and chemical properties. However, polyester has a disadvantage that it is stiff due to its high Young's modulus. In addition, since polyester fibers have almost no functional group having polarity in the molecule, they have a problem of insufficient hygroscopicity and can hardly absorb sweat and moisture when used for clothing, which is uncomfortable when worn. Further, there is a disadvantage that it is difficult to exhibit the feel of the natural fiber due to the slippery feeling unique to the synthetic fiber.

To solve these problems, in the textile industry, the cross-section of polyester filaments is spun into a cross-sectional shape such as a triangle or "Y" shape instead of a general circular cross section to improve hygroscopicity and dryness. . Among them, most of them are blended with cotton. However, cotton fibers have many short fibers, and therefore, there is a problem that the uniformity of the yarns is poor.

Because of its excellent mechanical and chemical properties, polyester fibers, which are widely used in clothing and industrial applications, and lyocell fibers, which are known as environment-friendly fibers, can be mixed into yarns to provide yarns with excellent mechanical properties and excellent dyeability and hygroscopicity .

Thus, in the Korean Patent Publication No. 2012-0132600, a mixed yarn obtained by spinning three yarns of polyester yarn with a twist of 300 to 1000 T / M and judging from the micro tencel yarn as a surface yarn, And a core yarn to a sheath ratio of 10 to 30%: 90 to 70%.

The above prior art is a spinning yarn in which a polyester yarn and a Tencel yarn are organized in the form of a sheath core, and the polyester filament yarns of the yarn end part act as wicks so that the knitted fabric made of the yarn has good draftability and a sense of elasticity, Since the twist is formed by the twisted structure as in the examination of the blood, there is a problem that a large number of teeth are generated and the frictional resistance is weak.

This problem is not only a problem of yarn spinning, but also in the case of knitting a knitted fabric with such a composite spinning yarn.

On the other hand, in the prior art, a knitted fabric using a polyester-lyocell air jet mixed yarn capable of knitting with a mixed yarn made of polyester and lyocell fibers and maximizing the performance possessed by the mixed yarn is disclosed.

However, the above-mentioned prior art has a disadvantage in that the functionality is poor.

It is an object of the present invention to provide a knitted fabric which can be produced by spinning yarns made of polyethylene phthalate and polypropylene and knitted using the knitted yarn to be applied to a bedding or the like.

It is an object of the present invention to provide a process for producing a spun yarn by mixing a polyethylene phthalate fiber and a polypropylene fiber, Coating the wax on the surface of the yarn; And a third step of curing the spun yarn to which the wax is applied in the second step. The method for manufacturing the double-side jacquard knitted fabric according to the waxing condition of the human-friendly spinning yarn.

In the first step, the polyethylene phthalate fiber and the polypropylene fiber are mixed at a weight ratio of 80:20.

The second step is characterized in that the wax is applied two to three times.

On the other hand, a knitted fabric using a yarn produced by the above-described manufacturing method, comprising: an inner sheet woven with a wax-coated yarn; An outer sheet woven with a polyethylene phthalate fiber disposed outside the inner sheet; And a heat-insulating filler inserted between the inner sheet and the outer sheet. The two-sided jacquard knitted fabric according to the waxing conditions of the human-friendly spinning yarn can be achieved.

According to the present invention, the woven fabric is waxed with poly (ethylene phthalate) and polypropylene to facilitate the formation of tissues, improve the functionality, and lightweight and antimicrobial properties.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flow chart showing a method for producing a waxed yarn according to the present invention,
2 is a cross-sectional view showing an example of a woven fabric using a waxed yarn according to the present invention.

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

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. It does not mean anything.

In addition, the sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation, and the terms defined specifically in consideration of the configuration and operation of the present invention may vary depending on the intention or custom of the user, operator It should be noted that the definitions of these terms should be made on the basis of the contents throughout this specification.

FIG. 1 is a flow chart showing a method for producing a waxed yarn according to the present invention, and FIG. 2 is a sectional view showing an example of a woven fabric using a waxed yarn according to the present invention.

As shown in FIGS. 1 and 2, a method of manufacturing a waxed yarn according to the present invention includes a first step S1 of mixing a polyethylene phthalate (PET) fiber and a polypropylene (PP) fiber to produce a yarn; (S2) of applying and coating wax on the surface of the yarn; And a third step (S3) of curing the spun yarn coated with the wax in the second step (S2).

In the first step (S1), polyethylene filament fiber and polypropylene fiber are mixed to produce a yarn.

Polyethylene phthalate is a long fiber having antibacterial, deodorizing and flame retarding properties.

In the embodiment of the present invention, the mixing ratio of the polyethylene phthalate fiber to the polypropylene fiber is selected to be approximately three.

That is, the polyethylene phthalate fiber and the polypropylene fiber are mixed at a weight ratio of 70 to 90: 10 to 30.

(Example)

a) If the weight ratio of the polyethylene phthalate fiber and the polypropylene fiber is 70: 30, the formation of the structure becomes difficult.

b) When polyethylene terephthalate fiber and polypropylene fiber are used in a weight ratio of 80:20, the formation of the structure is easy and the functionality can be improved. Therefore, knitting is the easiest.

c) When polyethylene terephthalate fiber and polypropylene fiber are used in a weight ratio of 90:10, the formation of the structure is easy, but the functionality is deteriorated.

Therefore, it is most preferable to prepare the yarn by setting the weight ratio of polyethylene phthalate fiber and polypropylene fiber to 80:20.

After the polyethylene phthalate fiber and the polypropylene fiber are mixed, a spun yarn is obtained through air jet spinning.

For example, the polyethylene phthalate fiber has a fiber fineness of 1.0 to 2.0 dtex, a fiber length of 35 to 40 mm, a strength of 3.5 to 5.0 g / dtex, and an elongation of 20 to 40%.

The polypropylene fiber has a fiber fineness of 1.0 to 2.0 dtex, a fiber length of 35 to 40 mm, a strength of 3.5 to 4.5 g / dtex, and an elongation of 10 to 20%.

Accordingly, the present invention is able to obtain a knitted fabric having a uniform pattern by repeatedly knitting a yarn having physical properties of a polyethylene phthalate fiber and a polypropylene fiber mixed yarn.

(Example)

Polyethylene phthalate fibers and polypropylene fibers were used to select the blend ratio with the highest functionality and then mixed with polyethylene terephthalate fiber and polypropylene fiber using a Murata Vortex spinneret using a ceramic nozzle. .

This mixed yarn is produced by mixing yarn fibers cut to a predetermined length and mixing them to produce a sliver. After softening the yarn, drafting is performed to reduce the fineness of the sliver. Murata Vortex, equipped with an air nozzle, And then supplied to a spinning machine to form a spinning yarn.

Polyethylene phthalate fibers and polypropylene fibers are cut into filaments and cut into tows.

In the second step (S2), wax is applied to the spun yarn prepared above twice or three times and waxed.

If waxing is done more than 3 times, it becomes difficult to knit and refining process becomes difficult, so wax only 2 ~ 3 times.

The knitted fabric is woven using the yarn produced by the above-described manufacturing method.

Woven knitted fabrics are mainly applied to bedding because they are light and have antibacterial properties.

As shown in FIG. 2, the knitted fabric using the yarn produced by the above-described manufacturing method according to the present invention,

An inner sheet 100 woven with a wax-coated yarn;

An outer sheet (200) woven with a polyethylene phthalate fiber disposed on the outside of the inner sheet;

And a heat insulating filler 300 inserted between the inner sheet and the outer sheet.

The inner sheet 100 is produced by weaving yarn spun yarn, and the yarn spun yarn is made by mixing polyethylene phthalate fiber and polypropylene fiber at a weight ratio of 80:20.

Then, wax is applied to the surface of the spinning yarn two or three times and waxed.

Therefore, a certain amount of the thermosetting filler material 300 is filled in the space between the inner sheet 100 and the outer sheet 200 to provide a warmth, and the sanitary knitted fabric can be provided with excellent antibacterial properties.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
