Description

{WATER-PROOF FABRIC USING INTERLACE THREAD USING INTERLACE YARN}

The present specification relates to a waterproof fabric and a manufacturing method thereof.

In general, a waterproof fabric can mean a fabric that does not allow water to pass through. The waterproof fabric can be applied not only to tents, but also to outdoor clothing such as climbing clothes, ski clothes, outdoors clothes, sleeping bags, and the like, and its application range is widening.

On the other hand, it is possible to consider the use of interlace yarn as a yarn of a waterproof fabric. The manufacturing process of the fabric using the interlaced yarn is superior to that of the elliptical yarn in terms of time and cost because the sizing step can be omitted and the washing step can be simplified in comparison with the manufacturing process of the fabric using the general yarn.

However, since the thickness of the interlaced yarn is not uniform or uniform, the size of the pinhole, which is the spacing space between the yarns, may be larger than the pinhole of the fabric using the normal yarn. Therefore, the fabric using the interlaced yarn may be more vulnerable to the waterproof function than the fabric using the normal yarn.

On the other hand, the carding unit parts 120 and 120-1 may be in a state where the fiber bundles are opened to each other. The overlap portions 110 and 110-1 and the flower weir portions 120 and 120-1 may be alternately and repeatedly arranged.

3, the maximum width W4 of the carding unit 120-1 may be greater than the maximum width W3 of the interlocking portion 110-1 in the interlaced yarn 100-1 before the shape modification. That is, the interlaced yarn 100-1 before the shape deformation may have a periodically curved shape.

The shape-modified interlace yarn 100 may have a uniform thickness in comparison with the interlace yarn 100-1 before the shape deformation. That is, the degree of change in the thickness of the deformed interlace yarn 100 may be smaller than the degree of change in the thickness of the interlace yarn 100-1 before the deformation.

In some embodiments, the shape-modified interlace yarn 100 may have a shape such that the maximum thickness W2 of the carding unit 120 is greater than the maximum thickness W1 of the wedge 110 as in the embodiment of FIG. . The ratio W1 / W2 of the maximum width W1 of the wedge portion 110 to the maximum width W2 of the carding unit 120 is the ratio of the width W1 / W2 of the carded portion 120-1 of the interlaced yarn 100-1 before the deformation, (W3 / W4) of the maximum thickness (W3) of the overlapping portion (110-1) to the maximum thickness (W4) That is, the shape-modified interlace yarn 100 may have a smaller difference in thickness between the interlaced yarn 100 and the interlaced yarn 100-1 than before the shape modification. However, it should be understood that the present invention is not limited thereto.

In some embodiments, the ratio W1 / W2 may be greater than or equal to 0.7 and less than or equal to 1, and the ratio W3 / W4 may be greater than or equal to 0 and less than or equal to 0.5. However, it should be understood that the present invention is not limited thereto.

In some embodiments, the maximum thickness W2 of the carding segment 120 of the deformed interlace yarn 100 is greater than the maximum width W2 of the carding segment 120-1 of the interlaced yarn 100-1 before deformation And may be smaller than the thickness W4.

In some embodiments, the maximum thickness W1 of the wedge portion 110 of the deformed interlace yarn 100 is greater than the maximum width W1 of the wedge portion 110-1 of the interlaced yarn 100-1 before deformation May be larger than the thickness (W3). However, the present invention is not limited thereto.

In some embodiments, the maximum thickness W1 of the wedge portion 110 of the deformed interlace yarn 100 is greater than the maximum width W1 of the wedge portion 110-1 of the interlaced yarn 100-1 before deformation And may be substantially the same as the thickness W3. However, the present invention is not limited thereto.

Although not shown, in other embodiments, the thickness of the deformed interlace yarn 100 may be uniform / constant. That is, the maximum thickness of the bridge portion 110 and the maximum thickness of the carding unit 120 may be substantially the same.

2 and 3, the shape-modified interlace yarn 100 is formed in such a manner that the width of the overlap portion 110 and the number of the carded portion 120, as compared with the interlace yarn 100-1, May be smaller than the area of the area D2 defined by the overlapping portion 110-1 and the columnar portion 120-1.

That is, since the waterproof fabric 10 includes the deformed interlace yarn 100, the spacing between the yarns can be made narrower than the fabric made of the interlaced yarn 100-1 before the shape deformation, Thus, the fabric made of the deformed interlace yarn 100 can be superior in terms of the waterproof function to the fabric made of the interlace yarn 100-1 before the deformation.

In some embodiments, the waterproof fabric 10 may include weft A and warp B. The weft yarn A may refer to the yarn in the width direction of the waterproof fabric 10 and the warp yarn B may refer to the yarn in the length direction of the waterproof fabric 10. [ The width direction and the longitudinal direction may be mutually perpendicular, but are not limited thereto. As in the embodiment of FIG. 1, the weft yarns A and the warp yarns B may be composed of interlaced yarns 100 of a deformed shape. However, the present invention is not limited thereto.

The waterproof fabric 20 according to another embodiment of the present disclosure includes weft A and warp B. [ The weft yarn A may be formed of deformed interlaced yarn 100 and the warp yarn B may be formed of another yarn 200. Here, the other yarn refers to the yarn other than the deformed interlaced yarn 100 as a whole. Needless to say, the interlaced yarn 100-1 may be included before the shape deformation.

The waterproof fabric 30 according to another embodiment of the present invention includes weft A and warp B. [ The warp yarns B may be formed of deformed interlaced yarn 100 and the warp yarns A may be formed of different yarns 200. [ Herein, the other yarns are collectively referred to as the yarn other than the deformed interlaced yarn 1000. It goes without saying that the interlaced yarn 100-1 before the shape modification is included.

Next, a method of manufacturing the waterproof fabric 10 according to the embodiment of the present invention will be described.

6 is a flowchart illustrating a method of manufacturing a waterproof fabric according to an embodiment of the present invention.

Referring to FIGS. 1 to 3 and 6, a method for manufacturing a waterproof fabric according to an embodiment of the present invention can be performed including a series of steps performed in chronological order. First, the interlaced yarn 100-1 The shape is changed by applying tension (S610).

In some embodiments, the step S610 of applying the tension to the interlaced yarn 100-1 to deform the shape (S610) is such that one end of the interlaced yarn 100-1, as in the embodiment of Fig. 7, And pulling the other end of the optical fiber 100-1.

More specifically, one end of the interlaced yarn 100-1 can be fixed by holding the one end of the interlaced yarn 100-1 with the fixing means 710. In this fixed state, Tension can be applied to the interlaced yarn 100-1 through the process of pulling or moving the interlaced yarn 100-1 so that the interlaced yarn 100-1 is tightened while holding the other end of the yarn 100-1.

In some embodiments, the step S610 of applying the tension to the interlaced yarn 100-1 to deform the shape (S610) may simultaneously apply tension to one end and the other end of the interlaced yarn 100-1 . &Lt; / RTI > That is, it can be performed in such a manner that one end and the other end of the interlaced yarn 100-1 are simultaneously pulled.

Specifically, the first moving means 810 moves the interlaced yarn 100-1 while the second moving means 820 moves the interlaced yarn 100-1 while holding the other end of the interlaced yarn 100-1. The tensile force can be applied to the interlaced yarn 100-1 through the process of pulling or moving the first moving means 810 and the second moving means 820 such that the first moving means 810 and the second moving means 820 are stretched. At this time, the moving direction of the first moving means 810 and the moving direction of the second moving means 820 may be opposite directions as shown in FIG. The first moving means 810 can be moved to the left in the drawing of Fig. 8, and the second moving means 820 can be moved to the right in the drawing of Fig. As a result, it is possible to uniformly apply the tension to the interlaced yarn 100-1, thereby uniformly deforming the shape of the interlaced yarn 100-1 as a whole.

In some embodiments, applying the tension to the interlaced yarn 100-1 to deform the shape (S610) may cause the interlaced yarn 100-1 to be deformed at one end of the interlaced yarn 100-1, Applying tension to the interlaced yarn 100-1, and then applying a tension to one end of the interlaced yarn 100-1 in a state where the other end of the interlaced yarn 100-1 is fixed.

8, in a state where one end of the interlaced yarn 100-1 is fixed to the first moving means 810, the second moving means 820 moves the interlaced yarn 100-1 The other end of the interlaced yarn 100-1 is held by the second moving means 820 while the other end is pulled or moved so that the interlaced yarn 100-1 is tightened, The moving means 810 may hold one end of the interlaced yarn 100-1 and perform a process of pulling or moving the interlaced yarn 100-1 so that the interlaced yarn 100-1 is stretched. As a result, it is possible to uniformly apply the tension to the interlaced yarn 100-1, thereby uniformly deforming the shape of the interlaced yarn 100-1 as a whole.

The shape-modified interlaced yarn 100 produced through the execution of the above-described step S610 may be uniform in thickness as compared with the interlaced yarn 100-1 before the shape deformation. When the above-described step S610 is completed, the deformed state of the interlaced yarn 100 can be maintained even if no further tension is applied to the deformed interlaced yarn 100. [

Next, the fabric is woven using the deformed interlaced yarn 100 (S620).

In some embodiments, the fabric comprises yarn A and warp B as in the embodiment of Fig. As in the embodiment of FIG. 1, the weft yarn A and the warp yarn B may be formed of the deformed interlaced yarn 100, but the present invention is not limited thereto. For example, as in the embodiment of FIGS. 4 and 5, A) and the warp yarns (B).

Next, referring to FIG. 6, the woven fabric is washed with water (S630). The present step S630 is a step for removing contaminants such as when the fabric is buried in the steps S610 and S620. Specifically, since the fabric is woven using the interlaced yarn 100-1, the sizing step of feeding the grass or the like may be omitted, so that in this step S630, May not be included. Accordingly, the time and cost can be reduced compared with the washing process of the fabric including the sizing step.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be appreciated that many variations and applications not illustrated above are possible. For example, each component specifically shown in the embodiments of the present invention can be modified and implemented. It is to be understood that all changes and modifications that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
