Description

Cloth product capable of absorbing water to store temperature and manufacturing method thereof

The invention relates to a cloth, in particular to a cloth which can absorb water to store temperature.

Various products that cool the body, such as cold towels, are introduced in the market. Most of the structures of these products are made by directly coating the superabsorbent resin particles in the fabric by means of tailoring. When you need to use it, put the product in ice water and soak it, then bring it into contact with the skin, which can produce a cool feeling. However, the superabsorbent resin particles are apt to bleed out from the cloth due to absorption of water, which causes the skin to feel sticky, and the cloth may be uneven after drying, resulting in poor appearance and inconvenient use, and high in the next use. The reduction of the water-absorbent resin particles also has a problem that the cooling effect is lowered.

Accordingly, it is an object of the present invention to provide a fabric which is water absorbing and which is easy to maintain flat and which can absorb water for storage.

Therefore, the present invention provides a cloth material capable of absorbing water for storage, comprising: two layers of hydrophobic non-woven fabric and a water-absorbent non-woven fabric interposed between the two layers of hydrophobic non-woven fabrics, the three layers of non-woven fabric are stacked and the periphery is pressed and fixed. And the inner area surrounded by the periphery is combined by local point pressure. The water-absorbent non-woven fabric contains water-absorbing fibers, and the water-absorbing fibers are fixed in the non-woven fabric, and are not easily lost like the super-absorbent resin particles after water absorption, and the hydrophobic non-woven fabric can effectively block the water-absorbent non-woven fabric from being exposed, and the surface of the cloth can be avoided. Too wet. In addition, the combination of stacking point pressure and pressure will fix the thickness of the water-absorbent non-woven fabric, so that when the water-absorbent non-woven fabric is pulled by external force, even if the fiber is broken, it will be fixed within a certain range without fiber displacement. The overall cloth is partially concentrated and partially uneven and flattened; and the groove formed after the pressure is pressed to make the water more easily absorbed into the absorbent non-woven fabric.

Preferably, the water-absorbent nonwoven fabric contains highly absorbent cotton fibers, polyethylene terephthalate fibers (PET) and polypropylene fibers (PP), and is produced by needle rolling. The choice of hydrophobic polyethylene terephthalate fiber and polypropylene fiber can control the surface of the cloth without feeling too wet, and can strengthen the strength of the high absorbent cotton and avoid the loss caused by external force pulling.

Preferably, the cloth which can absorb water to store temperature further comprises two outer cloths respectively stacked on the outer sides of each of the hydrophobic nonwoven fabrics, each of the outer cloths having an inner surface facing the hydrophobic non-woven fabric, and the inner surface The surface is sanded. Adding a layer of outer cloth can make more visual changes, and the inner surface of the sanded hair will produce hairiness. The capillary phenomenon of the hairiness helps to transfer the moisture inside the outer cloth to the outside.

Preferably, each of the outer sheets further has an outer surface on the opposite side of the inner surface, and the outer surface is printed with a pattern by thermal transfer.

Preferably, the hydrophobic nonwoven fabric is made by processing a polypropylene fiber by a needle punching process.

Alternatively, the cloth that absorbs water to store temperature selects different processing methods, two layers of hydrophobic non-woven fabric and one layer of water-absorbent non-woven fabric sandwiched between two layers of hydrophobic non-woven fabrics, the three layers of non-woven fabric are stacked and needle-rolled. Way to make and combine.

Another object of the present invention is to provide a method for producing a cloth which absorbs water and stores temperature in a water-absorbing and easy-to-smooth manner.

Thus, a method for fabricating a cloth that absorbs water for storage, the method comprising the steps of: preparing a water-absorbent non-woven fabric by mixing high-absorbent cotton fibers, polyethylene terephthalate fibers, and polypropylene fibers; Prepared by needle rolling; preparing two layers of hydrophobic non-woven fabric, each layer of hydrophobic non-woven fabric is made by using hydrophobic needles by water needle needle rolling; the water absorbent non-woven fabric is arranged between the two layers of hydrophobic non-woven fabrics, so that the three layers The non-woven fabric is stacked and hot-melt-bonded in a point-pressing manner; and the three-layer non-woven fabric which is fixed by point pressure is cut, and the peripheral sealing edge is press-fixed by heat fusion.

Preferably, the water-absorptive nonwoven fabric is further subjected to a heating step before it is superposed with the hydrophobic nonwoven fabrics, and the heating temperature only heat-melts the polypropylene fibers therein. After the hot melted polypropylene fiber is solidified, the water absorbent nonwoven fabric will be more tightly bonded.

Preferably, the pressure points formed by the three layers of non-woven dot pressing are arranged in a checkered line. In addition to having a better appearance, the plaid line also has the effect of separating the water-absorbent non-woven fabric into a plurality of ranges, so that when the cloth is pulled by an external force, the fiber of the water-absorbent non-woven fabric is restricted to a certain extent if it is broken. Within the scope, the overall quality of the fabric can be kept even and even.

Preferably, the method for fabricating a cloth that absorbs water for storage further comprises the steps of: preparing an outer cloth, one side of the outer cloth is subjected to sanding treatment; and stacking the outer cloth on each of the hydrophobicity The outer side of the non-woven fabric is oriented with the sanded side facing the hydrophobic non-woven fabric, and is crimped and fixed by hot-melt sealing.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Referring to Fig. 1, a preferred embodiment of the present invention which can absorb water to store temperature can be applied to various cloth products, such as a towel, a vest, a hat, and the like.

The preferred embodiment is formed by stacking five layers of fabric on each other, and comprises a layer of absorbent non-woven fabric 1, two layers of hydrophobic non-woven fabric 2 and two layers of outer fabric 3 from the inside to the outside. That is, the water-absorbent non-woven fabric 1 is interposed between the two layers of the hydrophobic non-woven fabric 2 and the two outer fabrics 3 are respectively stacked on the outer side of each of the hydrophobic non-woven fabrics 2, wherein the water-absorbent non-woven fabric 1 and the two-layer hydrophobic non-woven fabric 2 are first superposed. After being together, it is superimposed with two layers of outer cloth 3, and the specific production methods are as follows:

Referring to FIG. 2 to FIG. 5, the manufacturing method of the preferred embodiment includes the following steps:

Step 41: A water-absorbent nonwoven fabric 1 was prepared. The water-absorbent non-woven fabric 1 is obtained by mixing high-absorbent cotton fiber, polyethylene terephthalate fiber and polypropylene fiber and then needle-rolling. The ratio of the three kinds of fibers and the density of needle rolling can be made according to the use requirements of the product. Adjustments, for example, to increase the water absorption of the product, can increase the proportion of highly absorbent cotton fibers. Further, the water-absorbent non-woven fabric 1 can be subjected to a heating step, and the heating temperature only heat-melts the polypropylene fibers therein, and after the polypropylene fibers are cooled and solidified, the consolidation effect on the highly absorbent cotton fibers can be enhanced.

Step 42 prepares a hydrophobic nonwoven fabric 2. Each layer of the hydrophobic non-woven fabric 2 is produced by hydro-needle-needle-rolling of the hydrophobic fibers, and the non-woven fabric formed by the hydro-needle-needle rolling has micropores for allowing water to enter and exit. In the present embodiment, the hydrophobic nonwoven fabric 2 is made of polypropylene fibers.

Step 43 stacks the non-woven fabrics 1, 2 and combines them by hot pressing. As shown in FIG. 2 and FIG. 3, the water-absorbent non-woven fabric 1 is placed between two layers of hydrophobic non-woven fabric 2, and the three-layer non-woven fabrics 1 and 2 are stacked and hot-melt bonded by point pressing, as shown in FIG. The formed pressing points 21 may be arranged to form a pattern. In the present embodiment, the pressing points 21 are arranged in a checkered line, but they may be designed to have different patterns. Or, after mixing the high-absorbent cotton fiber, the polyethylene terephthalate fiber, and the polypropylene fiber, directly deposit the hydrophobic non-woven fabric 2 on the upper and lower layers thereof to form a three-layer structure like a sandwich, so that No need to deal with the pressure.

After the step 44 is cut, the periphery is closed and pressed. Referring to FIG. 4, the three-layer non-woven fabric 1 and 2 which are fixed by the point pressure are cut according to the required size, and the peripheral edge seal is press-fixed by hot melt to make the high-absorbent cotton fiber contained in the water-absorbent non-woven fabric 1 It is not exposed, and the inner region surrounded by the periphery is joined by local point pressure, thereby fixing the thickness of the water-absorbent non-woven fabric 1, so that when the water-absorbent non-woven fabric 1 is pulled by an external force, even if the fiber is broken, it is fixed at a certain degree. Within the scope, there will be no fiber displacement, resulting in partial bulging of the overall cloth and unevenness of partial sparse collapse. Furthermore, the groove formed by the pressure point 21 can make the water more easily absorbed into the water-absorbent non-woven fabric. 1 inside. The hot melt bonding method can be performed by ultrasonic hot melt pressing.

Step 45 prepares an outer cloth 3. On the outer cloth 3, the pattern is printed by the sublimation transfer technique, and one side is subjected to sanding treatment to produce a plurality of fine hairiness, which can absorb the water absorbed by the water-absorbent non-woven fabric 1 by means of capillary phenomenon. The portion (after cooling) is quickly brought to the other surface of the outer cloth 3 (as the outer surface of the cloth).

Referring to FIG. 1 together, in step 46, the outer cloth 3 is placed on the outer side of the hydrophobic non-woven fabric 2. The outer cloth 3 is placed on the outer side of each of the hydrophobic non-woven fabrics 2, and the sanded side is directed toward each of the hydrophobic non-woven fabrics 2, that is, the sanded side is the inner surface 31 of the outer cloth 3, on the inner surface. 31 is the opposite side and is printed with the outer surface 32 of the outer cloth 3, and is pressed and fixed by hot-melt sealing, that is, the upper and lower outer cloth 3 and the three-layer non-woven fabric 1 and 2 which have been pressed together. Combined with fixation. In the present embodiment, the outer cloth 3 is a microfiber cloth with a good touch, and the outer surface 32 is printed with a pattern, so that the cloth has a better touch and aesthetics. However, the outer cloth 3 may not be used, and the combination of the water-absorbent non-woven fabric 1 may be used only by the two layers of the hydrophobic non-woven fabric 2, and it may be used as a cloth.

The order of the above steps is only an explanation order used for convenience of explanation. Actually, some steps may be separately performed, for example, step 41, step 42 and step 45 may be separately performed.

In the specific application of the preferred embodiment, the cloth can be immersed in cold water with low temperature to make the water absorbent non-woven fabric 1 swell and swell, and the cloth can be taken out and squeezed out excess water, which can be used in contact with the skin. The skin feels cool by containing moisture with a lower temperature.

In summary, the fibers contained in the water-absorbent nonwoven fabric 1 of the present invention are entangled with each other, are less likely to be lost than the superabsorbent resin particles, and are further sandwiched between the upper and lower layers of the hydrophobic non-woven fabric 2 by point pressure hot-melt bonding. It is possible to prevent the loss of fibers to maintain high water absorption, and to keep them flat and not easily deformed, so that the object of the present invention can be achieved.
