Description

Synthetic textile Product having Moisture movement and Waterproof function and Method of manufacturing the Synthetic textile porduct

The present invention relates to a synthetic fiber product having a moisture-permeable waterproof function and a method for producing the synthetic fiber product.

Fibers are classified into natural fibers and chemical fibers (artificial fibers) according to their constituent raw materials. In addition, fibers made of synthetic polymers synthesized and polymerized from low molecular weight compounds in the chemical fibers are called synthetic fibers.

The synthetic fibers are slightly different in nature depending on the type, but compared to the natural fibers have a strong structure, such as abrasion resistance, strong tensile and friction, tough and difficult to wrinkle. In particular, low hygroscopicity (吸濕性), for example, even in a humid environment does not become heavy and maintains lightness. With the development of textile technology, high-performance synthetic fibers have been actively developed that do not lose their waterproof and windproof properties even under extreme conditions.

As the synthetic fiber products have many functions as described above, especially outdoor clothing, various wears, and equipment are made of synthetic fibers as the main material. In the case of clothing to keep warm, such as wool or down fleece, even if the outer fabric is all treated with synthetic fibers.

1 is a view schematically showing an outdoor jacket 11 as an example of a conventional synthetic fiber product.

As shown, the conventional general outdoor jacket 11, for example, to protect the body from rain and moisture as well as the synthetic fiber fabric 12 having a windproof and waterproof function so as not to become heavy by itself. It is made into the outer fabric. Inside the jacket 11 is a variety of thermal insulation material or other accessories are of course built.

The synthetic fiber fabric 12 is to sew pieces of synthetic fiber fabric cut into various shapes in accordance with the design of the jacket 11, as shown in the plurality of sewing parts 13 on the surface of the jacket 11 Expose The sewing unit 13 is an inevitable portion of the jacket 11 for sewing.

However, the above-described conventional jacket 11, even if the synthetic fiber fabric 12 has a number of cutting-edge functions, the problem of water leakage occurring in the sewing unit 13 to interconnect the synthetic fiber fabric 12 It has the disadvantage of being inevitable. The sewing unit 13 is formed with a fine needle hole through which the sewing needle passed, through which the water penetrates into the jacket 11.

Figure 2 is a cross-sectional view of sewing the outer fabric 15 and the lining using a sewing machine, shown to explain the problems with conventional synthetic fiber products.

Referring to the drawings, it can be seen that the outer fabric 15 and the lining 17 are tied and fixed by the upper and lower sewing threads 19a and 19b intertwined with each other. The sewing thread (19a, 19b) meet in the interior of the needle hole 21 through which the sewing machine needles are entangled to fix the outer fabric (15) and the lining (17).

Both the outer fabric 15 and the lining 17 may be a synthetic fiber fabric 12, the outer fabric 15 may be a synthetic fiber fabric, but anyway the outer fabric 15 and lining 17 The needle hole 21 is formed.

In any case, the needle hole 21 is maintained by the sewing thread (19a, 19b) is opened, in particular, the sewing thread (19a, 19b) serves as a wick to suck water, eventually the sewing portion 13 Water entered into one side passes through the fabric through the needle hole 21 and moves to the opposite side.

Even if the jacket 11 is made of a synthetic fiber fabric having a cutting-edge function, it is not possible to provide a perfect waterproof ability because there is no sewing section (13).

In order to solve this problem, there is a so-called seam sealing method in which a seam tape is adhered to the inner surface of the sewing unit 13. The seam tape is a high-frequency fusion (or thermocompression bonding) along the seam of the sewing unit 13 is a waterproof film for clothing to provide a waterproof to the sewing unit.

3 is a perspective view illustrating a state in which the waterproof seam tape 23 is attached to the sewing unit 13.

As shown, the seam tape 23 is attached along the seam of the sewing portion 13 formed in the synthetic fiber fabric 12. The seam tape 23 is in close contact with the synthetic fiber fabric 12 while covering the sewing unit 13 to block water from passing through the needle hole of the sewing unit 13.

However, the above-described shim sealing method has a disadvantage in that when the fabric 12 is thin, the shape of the shim tape 23 is exposed to the outside of the fabric as it is, and the corresponding portion is stiffer than other parts, which greatly deteriorates the merchandise. In addition, as the water washing or dry cleaning is repeated may be separated from the fabric 12 to fall. The seam tape, which began to peel off from the synthetic fiber fabric 12, proceeds to peel off and eventually becomes tattered, so that it can only be completely removed.

In addition, for example, when the seam of the sewing portion 13 is curved, it is almost impossible to completely adhere the belt-shaped seam tape 23 along the curved seam, and wrinkles are necessary on one side in the width direction of the seam tape 23. Because it can only occur as, the corresponding part of the fabric is crumpled, not only good aesthetics, of course, it was difficult to reliably seal the sealing.

In addition, since the ventilating work itself requires expensive equipment and advanced technology, manufacturing costs are inevitably high.

The present invention has been created to solve the above problems, despite the absence of ventilating, the perfect waterproof ability is maintained, providing a dry state at all times under any weather conditions, comfortable, good fit in clothing, sim tape It is an object of the present invention to provide a synthetic fiber product having a moisture-permeable waterproof function and a manufacturing method of the synthetic fiber product, as well as the various problems resulting from the.

Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

The method of manufacturing a synthetic fiber product having a moisture permeable waterproof function according to an embodiment of the present invention to be described later, the water-repellent treatment of a variety of synthetic fiber semi-finished products having a synthetic water support end on at least the outer surface (shell), water repellent waterproofing to the semi-finished product It is about the process of giving. Clothing and other products (bags, backpacks, hats, shoes, gloves, tents, etc.) made through the above method have a very strong water repellent effect because both the inside and the outside of the synthetic fiber fabric have water repellency. Have

The semi-finished product is a processing target to be manufactured as a finished product through a subsequent finished productization step. If the finished product is a garment, the zipper is already attached, but it is just before the attachment of any attachments including various ornaments or labels. .

In addition, when the finished product is a tent (41 in FIG. 7), it is a state before fixing an accessory such as a metal ring for fitting a pole into the tent cloth, and in the case of a backpack (45 in FIG. 8) or a glove (47 in FIG. 9). It is a state before all kinds of ornaments and attachments including various labels or a snap button or a velcro tape are applied. In addition, the semi-finished product to be made of the boot (49 in Fig. 10) is a state before the padding of the sole or string hole, the label and the attachment of various rubber materials.

Figure 4 is a flow chart showing the method of manufacturing a synthetic fiber product having a moisture-permeable waterproof function according to an embodiment of the present invention.

As shown, the method of manufacturing a synthetic fiber product having a moisture-permeable waterproof function according to the present embodiment begins with a semi-finished product call step (101). The semi-finished product call step 101 is a basic step, in which the prepared semi-finished product is called to remove various impurities attached to the semi-finished product. For example, it removes silicone or oil components such as wax or oil, other contaminants and dust during dyeing.

The bioprocessing step 103 then proceeds. The bioprocessing step 103 is a process in which the semi-finished product is added to the so-called Enzyme solution to which Enzyme enzyme is applied and washed. In the bioprocessing step, the temperature of the enzyme solution may be maintained at approximately 50 ° C. to 70 ° C., and the washing time is about 20 minutes to 60 minutes. In some cases, the washing time may be extended to 100 minutes.

When the semi-finished product is washed through the bio-processing step 103 as described above, the surface of the synthetic fiber fabric forming the semi-finished product becomes smooth (although the dehydration step is performed). The resin and the like are completely removed, so that the water-repellent solution, which will be described later, is effectively settled on the synthetic fiber fabric, thereby obtaining a firm water-repellent coating layer 25 on both the inner and outer surfaces of the synthetic fiber fabric. Of course, as the coating layer 25 is firmly maintained, the moisture permeable waterproof function of the finished product lasts long.

In addition, by the action of the enzyme, the texture of the synthetic fiber fabric becomes softer, the fiber of the synthetic fiber fabric becomes stronger, and the effect of improving the durability and added value of the finished product can also be obtained. The improvement of the texture and the increase of durability cannot be obtained with general chemical cleaning agents.

After the bioprocessing step 103 is completed, the dehydration step 105 is performed. The dehydration step 105 is performed using a general dehydration device, it is preferable to increase the dehydration rate as much as possible in order to lower the load of the first drying step 107 to be followed.

The primary drying step 107 following the dehydration step 105 is a process for preparing the water-repellent solution immersion step 109 to be completely dried semi-finished product. The drying method applicable to the primary drying step 107 includes steam drying, hot air drying, natural drying and the like.

Subsequent water-repellent liquid immersion step 109, the semi-finished product completely dried through the primary drying step 107, immersed in the prepared water-repellent liquid, so that the water-repellent liquid penetrates the yarn of the synthetic fiber fabric and coated after heat setting At the same time it is a process for filling the needle hole 21 formed in the sewing unit 13 in particular. Further details regarding this will be described later with reference to FIG. 5. The yarn is the warp yarn and the weft yarn of the fabric constituting the semi-finished product.

The concentration of the water repellent liquid used in the water repellent liquid immersion step 109 is, of course, depends on the type and thickness of the synthetic fiber fabric 12 constituting the semi-finished product. In addition, the water-repellent liquid immersion time may proceed to about 30 minutes to 2 hours. The water-repellent liquid immersion time also depends on the concentration of the water-repellent liquid and whether or not addition catalyst is added. Furthermore, if necessary, the water-repellent immersion process may be repeatedly performed two or more times in succession.

The dehydration step 111, which is a subsequent step of the water repellent liquid immersion step 109, is a process of removing the semi-finished product immersed in the water repellent liquid from the water repellent liquid and removing the remaining water repellent liquid coated on the semi-finished product. The dehydration method of the dehydration step 111 also employs a conventional dehydration method.

Subsequently, the secondary drying step 113 proceeds. The secondary drying step 113 is a process of drying the semi-finished product having completed the dehydration step 111 by using a separate drying device, in particular, the semi-finished product is not completely dried, but incompletely dried. Incomplete drying means drying with some moisture remaining in the semi-finished product. Dehydration rate of the semi-finished product through the secondary drying step 113 may be about 50% to 80%. By incomplete drying of the semi-finished product in this way it is possible to increase the efficiency of the subsequent heating setting step (115).

In the heating setting step 115 following the secondary drying step 113, the semi-finished product is heated in a temperature atmosphere of 140 ° C. to 200 ° C. for about 15 to 90 minutes to penetrate, adhere, and coat the semi-finished product. It is a process of fixing the sap to the coated place. As the semi-finished product passes through the curing device, the water-repellent liquid penetrated, adhered to, and coated on the yarn of the synthetic fiber fabric 13 and filled in the needle hole 21 is fixed in place.

A curing device can be used for this heating setting. The curing device is a device for moving a semifinished product to a conveyor and causing a heater disposed around the conveyor to heat the semifinished product. Of course, any other heating means can be applied for the heating setting.

Since the semi-finished product after completing the heat setting step 115 is in a stiff state, the flexible processing step 117 is performed to eliminate such stiffness. The flexible treatment step 117 is a process of, for example, washing the fibrous semi-finished product after the heat setting step in water to which the fabric softener is added in advance to soften its properties.

If the flexible treatment step 117 is completed, the dehydration step 119 is performed. The dehydration step 119 is a process of removing water from the fibrous semifinished product by using a general dehydration means.

The third drying step 121 is performed after the dehydration step 119. The third drying step 121 is a process of completely drying the fibrous semi-finished products by using the drying device used in the first drying step 107.

On the other hand, if necessary, the process from the water repellent liquid immersion step 109 to the third drying step 121 may be repeated two or more times. That is, the above process may be repeated depending on the type and thickness of the synthetic fiber fabric or the purpose of the finished product, or further, to further increase the moisture permeability of the product.

In addition, the water-repellent liquid immersion step 109, the heating setting step 115, the flexible treatment step 117 may be independently performed a plurality of times.

In any case, if the third drying step 121 is performed through the above process, the finished product is finished. The semi-finished product in the state where the tertiary drying step 121 is completed, the needle hole 21 is completely blocked by the water repellent fluid, and both the inner and outer sides of the synthetic fiber fabric is completely coated with the water repellent fluid. Moistureproof waterproof function.

Subsequently, the completed productization step 123 of completing the semi-finished product is performed. The finished product step 123 includes a series of processes for fixing, ironing, and packing any attachments such as accessories, labels, or other ornaments to the semi-finished product after tertiary drying.

It is natural that the processes performed in the finished productization step 123 are different from each other according to the type of semi-finished product. For example, in the case of the shoe shown in Figure 10, the process of fixing the strap hole and the label on the semi-finished upper and fixing the insole and other decorations is the finished product step.

Figure 5 is an enlarged cross-sectional view for explaining the characteristics of the fabric in the synthetic fiber product produced by the method of FIG.

Referring to the drawings, it can be seen that the needle hole (21 in FIG. 2) formed in the synthetic fiber fabric 12 is completely blocked by the water repellent fluid. The water-repellent liquid is a coating layer 25 as a part of the water-repellent liquid immersion step 109 penetrates into the needle hole 21 and is fixed in a state where the needle hole is completely filled to prevent water from passing through the needle hole. do.

6 is an example of a synthetic fiber product having a moisture-permeable waterproof function manufactured by the manufacturing method described with reference to FIG. 4, and illustrates a top 31 and a bottom 33 of a garment.

As shown in the figure, a coating layer 25 is formed on the surface of the yarn 35 constituting the synthetic fiber fabric 12 forming the top 31 and the bottom 33. The coating layer 25 completely protects the yarn 35 as a water repellent liquid penetrated and fixed to the yarn 35.

In particular, when the yarn 35 itself constituting the yarn 35 of the synthetic fiber fabric 12 is hygroscopic, the coating layer 25, for example, so that rain water does not penetrate into the interior of the fabric 12 to flow directly To prevent the top and bottom (31,33) from getting wet.

In addition, even when the yarn 35 is hydrophobic, rain water flows more quickly to provide a more reliable waterproofing function, and also prevents oxidation of the yarn in a state in which the yarn 35 is wrapped to prolong the life of the yarn 35. Let's do it.

In addition, since the needle hole of the sewing portion 13 formed in the upper and lower portions 31 and 33 is also filled with the water-repellent liquid, no matter how much the wind blows, there is no fear of water leaking into the garment.

Reference numeral 39 is a moisture vapor space. The moisture-permeable space 39 is a passage for discharging moisture or heat generated from the body. That is, since only the yarns are water-repellent coated and the gap and the gap of the fabric tissue are not coated, it can be seen that the coating layer 25 is formed so as not to fill the moisture permeable space 39.

FIG. 7 is a view illustrating a tent 41 made by the manufacturing method described with reference to FIG. 4.

Referring to the drawings, it can be seen that the coating layer 25 is laminated on the yarn 35 of the synthetic fiber fabric 12 constituting the tent 41. The coating layer 25, so that the water droplets such as rain or dew dropped in the tent can immediately roll down without staying on the tent (41).

In addition, since the needle hole of the sewing portion 13 formed in the roof of the tent 41 is also blocked by the coating layer 25 as described with reference to FIG. 5, even if a rainstorm is driven, the inside of the tent is opened through the needle hole. There is no worry of water seeping into it.

8 to 11 illustrate, for example, a backpack 45, gloves 47, shoes 49, and a hat 51 among various synthetic fiber products that can be manufactured by the manufacturing method described with reference to FIG. 4. Drawing.

As shown, the coating layer 25 is laminated on the yarn 35 of the synthetic fiber fabric 12 forming the outer surface (envelope) of the backpack 45, the gloves 47, the shoes 49, and the hat 51. It is. Thus, since the coating layer 25 of the water repellent is formed on the synthetic fiber fabric 12, even if rain, raindrops bounce off as it can be always kept dry.

In addition, since the needle hole of the sewing portion 13 formed in the glove 47 or the shoe 49 is also completely blocked by the water repellent liquid, water does not penetrate into the glove 47 or the shoe 49. The waterproof efficiency is good. The shoes 49 also include ugg boots, children's thermal boots, etc., which are popular in recent years.

In the case of gloves 47, no matter how much you touch the snow (snow) in winter, for example, it is more convenient in the ski resort. Shoes are also waterproof, so they won't seep in when it's raining or when you're walking around (like boots). Similarly, the hat 51 does not have moisture inside the hat 51, and at least there is no fear that the hairstyle will be damaged by moisture.

On the other hand, the quality inspection report attached below is a test report performed by the Korea Textile Technology Institute in accordance with the Japanese quality standards, showing the water repellent capacity of the synthetic water support constituting the synthetic fiber products according to the present invention.

As shown in the report, the specimen 1 and the specimen 2 were cut into three pieces, and after the water repellency test, all three pieces of specimen 1 received grade 3 (3 3 3). In all cases, all three pieces received a rating of 3 (3 3 3).

In the water repellency test according to the Japanese test standard (JIS L 1092), which is stricter and more stringent than Korea, the highest grade is grade 4, the upper grade is classified into three grades, and the second grade has passed the Japanese testing criteria.

In addition, all three pieces of each sample received the same grade (grade 3), which means that the water repellency of the fabric is uniform. That is, some parts of the same fabric have high water repellency and others have relatively low water repellency, but all three pieces have uniform water repellency. This disproves the uniformity, reproducibility and stability of the machining effect.

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, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
