DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a sheet-like mat. More particularly, it relates to a sheet-like mat used independently as a bedding such as a sleeping mat, a quilt, a cushion, a bed for a sick person or the like, or used with a cover such as a bed sheet or the like and capable of providing a comfortable resting environment by absorbing sweat emitted from a body of a user or a moisture in underwear, bedding or the like.
BACKGROUND ART
A bed sheet made of a woven fabric or a knitted fabric of a cotton fiber of the above kind of mat is known. Since cotton fiber has a superior hygroscopicity and water absorption, the cotton fiber can absorb sweat, moisture, blood or the like, to thereby prevent a sticky feeling due to sweat or the like.
However, even if the bed sheet is made of a cotton fiber or the like having superior water absorption properties, a water content which the bed sheet of the woven fabric or the knitted fabric can absorb is relatively low and the fabric is quickly saturated with the water. Therefore, in particular when bedding is used during hot weather, or is continuously used for a long term by a sick person, a problem arises in that the conventional bed sheet of cotton fiber or the like cannot sufficiently absorb the generated water content. Further, another problem arises in that a smell stemming from sweat, blood, water emitted from a human body or the like cannot be removed until the material is washed.
DISCLOSURE OF THE INVENTION
An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a sheet-like mat having a high water-absorbing ability and capable of maintaining a comfortable and dry environment without a stuffy condition caused by sweat and moisture, and less likely to cause bedsores, and if necessary, capable of eliminating bad smells.
The object of the present invention is achieved by a sheet-like mat comprised of a mat cover the inside of which is divided into a plurality of bag-like spaces, and a drying agent packed into a bag and contained in the bag-like spaces in such a manner that the drying agent cannot fall out of the bag-like spaces.
Since the drying agent is contained inside the sheet-like mat in accordance with the present invention, it is possible to provide a comfortable sleeping environment and prolong the bedding life, by absorbing a water content and moisture due to the sweat, blood, urine or the like in the bedding to maintain surfaces of the bedding, underwear or the human skin in a dry condition by suitably selecting a quantity of the drying agent.
It is possible to absorb the smell of sweat, blood or water emitted from the human body by adding a deodorant to the drying agent.
A magnesium sulfate, a high polymer absorbent, a silica gel or the like can be used as the drying agent.
When the magnesium sulfate MgSO.sub.4 .multidot.nH.sub.2 O, wherein 0.ltoreq.n<5, is used, it is possible to obtain a strong drying power, i.e., a strong water absorbing power, compared with silica gel, and a superior effect without a deliquescence. There is little danger of harm when magnesium sulfate is orally inhaled, and the magnesium sulfate can be regenerated, which are advantages obtained by the use of magnesium sulfate.
An activated alumina, a zeolite or an activated charcoal can be used as the deodorant.
When dividing the inside of the mat cover into a plurality of spaces and using the drying agent packed into bags, it is possible to change or regenerate the bags containing the drying agent.
More particularly, when a circumferential edge enclosing bag spaces of the mat cover can be freely opened and closed, insertion and removal of the drying agent are rapidly and easily accomplished.
When increasing the water absorption properties of a covering material of a front side, i.e., an upper side, of the mat cover, and reducing the water absorption properties of a back side, i.e., a lower side, of the mat cover, or using a back side material which is a nonwater absorption, water proof or a nonair permeable m
