Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a spiral coil yarn,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the production of functional fabric fabrics, and more particularly, to a spiral coil fabric having excellent dimensional stability and durability while having a three-dimensional shape, a fabric thereof, and a manufacturing method thereof.

In the field of synthetic fibers, yarns having various shapes and functionalities such as false wares have already been developed and commercialized and commercialized for various purposes. Most of artificial synthetic fibers have thermoplastic properties. By using these thermoplastic materials, it is possible to maximize characteristics inherent to the material through various heat treatment processes in the state of raw or fabric, and to easily apply new characteristics and deformation.

However, despite the ease of processing the yarn through such heat treatment, it is very difficult to manufacture a processed yarn with excellent shape stability and durability while having a three-dimensional spiral structure.

In other words, the yarn can be temporarily processed into a three-dimensional spiral shape by using the thermoplastic property, but there is no countermeasure for maintaining the spiral shape, so that deformation such as squeezing or depression of the spiral shape in the subsequent process or washing process occurs, It can not function properly as a three-dimensional space.

In some cases, attempts have been made to secure a space in which the eluting material has been placed through elution of the eluting material by a method of mixing the raw material with the main material or making the eluting material into a single fiber by blending the raw material with elution material. However, When the second elution occurs after spinning, the portion occupied by the eluting material temporarily forms a space, but since the shape of the main material is not stable, the space is quickly filled with the fiber material of the main material. There is no sense to secure.

Although spun yarn using natural fiber construction and construction of natural fibers have been developed, the shape of the raw yarn is hollow and the shape of the finished yarn is not a spiral coil shape that forms a three-dimensional space.

Spiral coil yarn is not only excellent in elasticity and elasticity but also can be used to develop excellent functional fabric products suitable for the season because it can manifest ventilation, noticeability, cold sensation, warmth and lightness depending on the composition of raw material .

Therefore, it is desired to develop a spiral type coil having excellent three dimensional shape and excellent shape stability and durability.

Figs. 4 to 6 are photographs of spiral coil yarns and their fabric fabrics according to the first to third embodiments of the present invention. Fig.

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

FIGS. 1 to 3 are schematic manufacturing steps for manufacturing a spiral coil yarn according to the first to third embodiments of the present invention and a fabric end of the same, wherein FIG. 1 shows a spiral coil yarn 16A of type A shown in FIG. FIG. 2 is a view showing a manufacturing process of the first embodiment for manufacturing the spiral coil yarn fiber fabric 20A and the spiral coil yarn fabric 20A. Fig. 6 is a manufacturing process diagram of the second embodiment for manufacturing. 3 is a process diagram related to the third embodiment for manufacturing the C type helical coil yarn 16C and the spiral coil yarn fiber cloth 20C shown in FIG.

In FIGS. 4 to 6, it is to be understood that the A, B and C type helical coil yarns 16A, 16B and 16C are provided with alphabets A, B and C in order to distinguish between the types.

In the present invention, a spiral coil yarn is manufactured. In order to improve shape stability and durability, a low melting point yarn 10 and a discharge yarn 12 are first used as an address material, and a twist yarn 14 is formed using the same.

The low metering point yarn (also referred to as LM yarn or low melting point yarn) 10 used in the present invention is a polyester material and serves as a skeleton of the helical coil yarns 16A, 16B and 16C. The melting temperature of the polyester polyester low melting point yarn 10 used in the present invention is in the range of 120 to 200 DEG C, which is relatively low compared with the melting point of a common polyester yarn. Therefore, the low melting point yarn 10 is melted at the time of heat treatment, then hardened and hardened at the time of heat treatment, and is bonded to the surrounding discharge yarn 12 at the time of fusion. The low melting point yarn 10 used in the present invention has a thickness of 10 to 300 denier and is preferably formed in the form of filament yarn bundles.

The dissolving out yarn 12 used in the present invention plays a role of forming a spiral three-dimensional space by melting and curing the low melting point yarn 10 remaining after melting and escaping by the dissolving solution, Materials include PLA (Poly Lactic Acid), PVA (Poly Vinyl Alcohol), and alkali-soluble CO-PET (CO-Poly ester).

The molten solder 12 is combined with the low melting point yarn 10 to form a helical coil shape, and is dissolved and removed by the molten solution injected after the heat treatment in the post-treatment process. PLA materials are more suitable for commercial and environmental use because they are expensive and PVA (CO-Poly ester) is environmentally polluted wastewater. . PLA material is called "corn fiber" and it is environmentally biodegradable. It is fused at 120 ~ 180 ℃ and easy to dissolve in Alkali solvent. The elution solvent of PVA material has a property of being easy to dissolve in water.

The inventors of the present invention have found that both the melting points of the low melting point yarn 10 and the melting point of the leaching yarn 12 have a common melting temperature range within a range of 120 to 200 DEG C , The problem that the low melting point yarn 10 can not be maintained in the coil shape due to melting of the molten yarn 12 due to melting and so forth during the heat treatment of the twist yarn 14 at the heat treatment temperature falling within the common melting range .

First, with reference to FIG. 1, a description will be given of a process of manufacturing an A-type helical coil yarn 16A and its coil yarn fabric 20A as shown in FIG.

In the first embodiment of the present invention, as shown in FIG. 1, a low-melting point yarn 10 and a molten filament yarn 12 having a melting point in a common melting temperature range of 120 to 200 ° C are combined (S1 Step) A twist yarn 14 is obtained.

The twisting / covering can be carried out by any kind of pliers or twisting machines having a pendulum and twisted yarn function, and the combination of the thickness of the low melting point yarn and the twisted yarn 12 can be varied according to the use and characteristics. The degree of twist in the combined yarn is preferably 200 to 4000 TPM (Twist Per Meter), and more preferably 300 to 3000 TPM. In order to obtain the A type helical coil yarn 16A as shown in Fig. 4 (a), the low melting point yarn 10 may be subjected to covering yarn drawing based on the discharged yarn 12.

After obtaining the twist yarn 14 by combining the low melting point yarn 10 and the lean yarn 12 as described above (Step S1 in Fig. 1), the twist yarn 14 is sintered at a temperature of 120 to 200 DEG C at a common melting temperature Melting point yarn 10 is fused to form a spiral skeleton. At this time, the dissolution yarn 12 is also fused in the same manner as the heat treatment to maintain the spiral skeleton (FIG. 1) do.

After the heat treatment is performed, only the leaching yarn 12 constituting the twisted yarn 14 is eluted with the leaching solution which melts the leaching yarn 12 (step S3 of FIG. 1). Therefore, a spiral coil yarn 16A as shown in Fig. 4 (a) is obtained while a space is formed at the position where the discharge yarn 12 has escaped from the twist yarn 14. [

The spiral coil yarn 16A of the type A shown in FIG. 4A has a helical tube type structure, so that the air can be faded, so that it has warmth. As a result of the experiment using the spiral coil yarn 16A of the type A as shown in Fig. 4 (a), it was found that not only the shape stability and the durability were excellent but also the lighter weight ratio was 30% or more, the elongation rate was 40% % Or more.

As described above, if the twisting yarn 14 is post-treated by fusion after heat treatment, it can be directly produced by the A-type helical coil yarn 16A. However, in order to ensure the commercialization and the morphological stability of the helical coil yarn It may be more desirable to obtain a spiral coil yarn fiber fabric 20A after the twisting yarn 14 is woven with the raw yarn support 18 and then subjected to heat treatment followed by elution.

That is, the low melting point yarn 10 and the leaching yarn 12 having a common melting temperature range within a range of 120 to 200 DEG C are jointly twisted to obtain the twist yarn 14 (Step S1 in FIG. 1) (Step S4 of FIG. 1) to obtain a living support section 18 and then heat-treating the living support section 18 (step S20 of FIG. 1) to construct a living support section 18 As shown in Fig. 4 (b), the melting point of the low melting point yarn 10 is made to melt, and the molten filament 12 is eluted with the eluting solution after the heat treatment fusion, The fabric 20A made of the spiral coil yarns by the skeleton structure of the yarn 10 is completed.

Next, with reference to FIG. 2, a description will be given of a process of manufacturing a B type helical coil yarn 16B and its coil yarn fiber fabric 20B as shown in FIG.

The B-type helical coil yarn 16B in the second embodiment of the present invention has a more spirally twisted form than the A-type helical coil yarn 16A, And elasticity is strongly expressed.

Referring to FIG. 2, the low melting point yarn 10 is firstly twisted in one direction (step S0 in FIG. 2). Next, the hot melt discharge yarn 12 having a common melting temperature range within a range of 120 to 200 DEG C and the low melting point yarn 10 previously twisted are combined (step S1 in FIG. 2) So that a twist yarn 14 is obtained. At this time, the low melting point yarn 10 wound in one direction is wound on one side in the opposite direction and is wound around the discharge yarn 12, so that a large bending and a bulkiness are generated. The twist yarn 14 obtained by this twist yarn is called a kabe-twist yarn.

In order to obtain the B-type helical coil yarn 16B directly from the above-mentioned twist yarn 14, the low melting point yarn 10 is fused to the twist yarn 14 through heat treatment (step S2 in FIG. 2) (A) of FIG. 5 in which a space is formed at the position where the discharged filament 12 is removed by eluting the filament 12 with the eluting solution (step S2 of FIG. 2) A spiral coil yarn 16B can be obtained.

As described above, the twist yarn 14 may be post-treated to be directly made into the B-type spiral coil yarn 16B as shown in FIG. 5 (a), but the commercialization and the morphological stability of the helical coil yarn are more excellent It is more preferable to obtain a spiral coil yarn fiber fabric 20B after the treatment by performing the heat treatment and elution after the weaving support yarn 18 is woven with the twist yarn 14 as a warp yarn.

That is, as shown in FIG. 2, the low melting point yarn 10 is twisted in one direction, and then the discharged yarn 12 having the common melting temperature range is combined with the twisted low melting point yarn 10 Step S1), and twist yarns 14 in the direction opposite to the direction of twist of the low melting point yarn 10 to obtain the twist yarn 14. [ 2). Then, the raw support section 18 is heat treated (step S20 in FIG. 2) to form a living support section 18, Melting point yarn 10 as a thermoplastic material constituting the thermosetting resin 18 is fused and cured and the leaching yarn 12 is eluted from the raw material support 18 with the eluting solution following the heat treatment fusion A fiber fabric 20B made of helical coil yarns 16B by the incorporated low melting point yarn 10 skeleton structure is completed as shown in Fig. 5 (b).

Finally, referring to FIG. 3, a process of manufacturing the C type helical coil yarn 16C and the coil yarn fiber cloth 20C as shown in FIG. 6 will be described.

The C type helical coil yarn 16C in the second embodiment of the present invention may be a helical coil yarn in which a function is added by using a composite material.

Referring to FIG. 3, in the third embodiment of the present invention, a composite material yarn 13 is obtained by first joining a different material yarn and a low melting point yarn 10 together. An example of the heterogeneous yarn 11 is cotton fiber yarn.

Cotton fiber yarn is human friendly and has good sweat absorption, but it is not fast drying. However, in the third embodiment of the present invention, a composite fiber yarn 13 including a cotton fiber yarn may be implemented to be made of a functional fiber yarn capable of quick drying on the characteristics of a cotton fiber yarn.

3, the composite yarn 13 is obtained, and the composite yarn 13 and the yarn introduction yarn 12 (hereinafter, referred to as " composite yarn 13 " (Step S12 in Fig. 3) to obtain the twist yarn 14. The twist yarn 14 is wound around the warp yarns 14a and 14b. This second order twist yarn 14 is also a kind of wall twist.

In order to obtain the C type helical coil yarn 16C directly from the twist yarn 14, the low melting point yarn 10 is fused to the twist yarn 14 through heat treatment (step S2 of FIG. 3) to form a helical skeleton 6 (a), in which a space is formed at the position where the discharged filament 12 is removed by eluting the filament 12 with the eluting solution (step S3 in Fig. 3) A coil yarn 16C can be obtained.

In the spiral coil yarn 16C of Fig. 6 (a), the relatively thin fiber yarn is a skeleton of low-density yarn 10 and the relatively thick yarn is a cotton fiber yarn.

As described above, the twist yarn 14 is post-treated to be directly made into the C type spiral coil yarn 16C as shown in FIG. 6 (a), but it is possible to make the twist yarn 14 more excellent in terms of commercialization and morphological stability of the helical coil yarn It is more preferable to obtain a spiral coil yarn fiber cloth 20C after the heat treatment followed by elution after the weaving support member 18 is woven with the twist yarn 14 as a warp yarn.

That is, as shown in FIG. 3, the composite yarn 13 is obtained by firstly twisting the heterogeneous yarn 11 such as a cotton fiber yarn with the low melting point yarn 10 (step S11 of FIG. 3) (Step S12 in Fig. 3) to obtain the twist yarn 14 by secondary jointing the yarn 13 and the filament yarn 12 (step S12 of Fig. 3). Then, the twisting yarn 14 is woven or knitted to obtain a living support portion 18 (Step S4 in Fig. 3) to heat the living support portion 18 (Step S20 in Fig. 3) Melting point yarn 10, which is a thermoplastic material constituting the support stage 18, is cured. Thereafter, as shown in FIG. 6 (b), the molten resin 12 is eluted from the raw support 18 with the eluting solution after the heat treatment fusion (step S30 in FIG. 3) The fabric 20C made of the spiral coil yarns 16C by the skeleton structure of the yarn 10 is completed.

The fabric fabrics 20A, 20B and 20C made of the spiral coil yarns 16A, 16B and 16C of the present invention formed by the methods of the first to third embodiments as described above have lightweighting rate, elongation rate, , Warmth (cold sensation), air permeability, and shape stability were all good.

The LM yarn as a low-temperature fusion material is combined with the PLA yarn as an eluting material to form a twist yarn 14 as a core part with PLA yarn, and a low-melting yarn is fused through heat treatment to form a skeleton A space is formed at a portion where the elution material (PLA) is eluted so that the yarn of the elution material has been formed, and the skeleton formed by fusion bonding of the LM yarn already has a function of maintaining and stabilizing the shape of the space, This is because spiral coil fiber fabrics are produced through fusion between materials having three-dimensional space and appearance.
