Description

Moisture absorbing cool cloth and method for preparing moisture absorbing and cooling sensation cloth

The present invention relates to a cloth, and more particularly to a moisture absorbing cool cloth and a method of preparing the moisture absorbing sensation cloth.

As people's demands for the comfort of clothes are getting higher and higher, the characteristics of hygroscopicity, quick-drying and non-sticking of the clothes have become the subject of extensive research, especially when the clothes absorb the moisture generated by a wearer. Or when sweat, the clothes will adhere to the wearer's skin, causing the skin to have a wet sticky discomfort.

In order to improve the discomfort, Taiwan Patent Publication No. 201326491 discloses a structure of a unidirectional moisture wicking fabric comprising a first rayon having a surface immersed in a moisture absorbing agent and a surface immersed or coated with water. a second rayon fiber, wherein the first rayon fiber and the second rayon fiber are interlaced to form a first surface and a second surface, and the second rayon fiber forms a plurality of micro on the second surface contacting the skin Raised structure. The patent utilizes the raised structures to separate the skin from the second surface that has absorbed sweat to achieve a dry, non-sticky effect.

Although the patent can improve the discomfort of wet adhesion, the convex structure causes the wearer's skin to always have the uncomfortable feeling of foreign matter, and the convex structure is absorbed or coated with a water repellent. Since the second fiber is formed, the convex structure does not have a moisture absorbing effect, so that the overall moisture absorption effect of the cloth is not good, and there is a problem that the cooling effect is insufficient.

In addition, in order to improve the feeling of discomfort, Chinese Patent Publication No. 101370978A discloses a morphologically varying fiber cloth comprising a fiber cloth layer and a patterned water-swellable layer provided with protrusions on at least one side of the fiber cloth layer. The water-swellable layer is formed of a water-insoluble water-swellable resin. The fiber cloth is a woven fabric, a woven fabric or a non-woven fabric. The raw material of the fiber cloth is synthetic fiber, recycled fiber, natural fiber, or any combination thereof. The water-insoluble water-swellable resin refers to a resin which is substantially water-insoluble in a use environment and which absorbs water and swells in the presence of moisture or water, for example, a starch-acrylic graft-based resin, polyacrylic acid chloride A resin, a polyvinyl alcohol-based resin, a polyether urethane resin, a polyester urethane resin, or a polyester-polyether urethane resin. The water-swellable layer in the morphological change fiber cloth swells by sweat or condensation generated by exercise or the like, thereby generating a stress, and the fiber cloth layer is driven by the stress to cause a morphological change of the fiber cloth layer, and when drying, The water-insoluble water-swellable resin in the water-swellable layer shrinks, so that the stress disappears, and the fiber cloth layer is restored to the original state. The patent utilizes the water-swellable layer to separate the skin from the sweat-absorbent fiber cloth layer to achieve a dry and non-sticky effect, and at the same time, the skin is absorbed and the sweat is absorbed by utilizing the morphological change of the fiber cloth layer. The contact area of the fiber cloth layer is reduced, and the effect of dryness and non-stickiness is enhanced.

Although the patent can improve the discomfort of wet adhesion, the water-swellable layer causes the wearer's skin to always have the uncomfortable feeling of foreign matter. Moreover, after the morphological change fiber cloth is washed a plurality of times, the water swellable layer is easily detached from the fiber cloth layer, so that the service life of the morphological fiber cloth is not satisfactory.

Accordingly, it is an object of the present invention to provide a absorbent sensation fabric that is at least capable of solving one of the disadvantages described in the prior art.

Accordingly, the absorbent sensation fabric of the present invention comprises a cloth body comprising a plurality of interwoven yarns, and a plurality of hydrogel particles which are pressed between the yarns of the cloth body.

Therefore, the method for preparing a moisture-absorbing and cooling sensation fabric comprises the steps of: (a) mixing a liquid gel matrix with a crosslinking agent to form an emulsion, wherein the liquid gel matrix comprises a precursor hydrogel. And a solvent comprising a plurality of hydrogel particles formed by gelation of the precursor hydrogel with the crosslinking agent; and step (b) printing the emulsion onto a cloth body, The hydrogel particles are caused to be trapped between a plurality of interwoven yarns of the cloth body.

The effect of the present invention is that the hydrogel particles are pressed between the yarns of the cloth body, and when the wearer wears the moisture-absorbing cool cloth, the uncomfortable feeling of foreign matter does not always occur, and when When the hydrogel particles absorb the moisture or sweat generated by the wearer, the surface of the moisture-absorbing sensation fabric is formed with a plurality of spaced-apart protrusions and a plurality of channels are defined by the protrusions. The wearer's skin and the moisture-absorbing and cooling sensation absorbing moisture or sweat are separated by the protrusions to improve the discomfort of wet adhesion, and further, the hydrogel particles have the property of absorbing moisture or sweat and The ventilation effect produced by the equal channel enables the sweat to be quickly absorbed and volatilized and accelerates the absorption of the moisture-absorbing moisture-absorbing cloth to achieve a dry and cool effect.
