The present invention relates to a bed sheet having excellent washing durability, and more particularly, to a bed sheet in which laundry durability is added to a sheet having a waterproofing property that absorbs secretions such as sweat or urine and prevents the absorbed moisture from being exuded out of the sheet. .

In general, people who are not free to move, such as infants and patients, the ability to control the urine, etc., depending on the doctor is less common, it is common to exempt from lying down. Therefore, in order to protect the bedding used by the above to some extent from the above wastes, in general, a double sheet of vinyl sheets and linen half sheets are generally used on the bedding.

However, this method is not only troublesome to manage, but also has a disadvantage in that the sheets laid on the vinyl sheet, such as linen half sheets, have low absorbency and thus hardly absorb secretions such as patients and flow out of the sheets to contaminate the other side.

Absorption with high fluid uptake and high fluid retention per weight to solve this problem, i.e., to be preferably used for incontinence pads, diapers, surgical swabs, bed sheets, sanitary napkins (menstrual bands), etc. Sheets have been proposed, for example, the "absorbent sheet" of patent application 1985-0006083 relates to an absorbent sheet product which absorbs liquids rapidly and has a high liquid retention, which is mixed with entangled blown polymer fibers and their extracted polymer fibers. While the absorbent sheet discloses an absorbent sheet comprising a super absorbent liquid absorbent fibers, wherein the superabsorbent fibers have a synthetic urine retention rate of at least about 5 ml / g, the absorbent sheet also has a satisfactory absorbency level. In particular, the sheet has absorbed water, although the absorbency has improved. Not held by drying and breathable as well as therefore good to not feel good to you is a good environment to various pathogens growth is not desirable in a sanitary manner.

In addition, as described above, bedding such as bed sheets, various bacteria such as staphylococcus aureus, pneumococci, Escherichia coli, and mites breed, causing various diseases, atopic dermatitis, and allergies in humans, thereby preventing healthy living. In particular, problems caused by these bacteria can cause serious problems in children, the elderly, patients and the like. However, in the past, as a method of preventing such bacteria, a method of substantially boiling, drying, and brushing sheets was generally used. In order to solve these problems, Korean Patent Application No. 2002-0027051 discloses antimicrobial, insect repellent, and antistatic properties. "Woven pads made of a woven fabric made of interlaced warp and weft yarns, which are excellent in prevention, etc., wherein the fabric pad is selected from polyester, nylon, acrylic, polypropylene, or a mixture thereof. 5 to 15% by weight of gannetite fiber yarn, in which 1 to 12 parts by weight of gannetite powder is dispersed with respect to 100 parts by weight of synthetic resin; 0.5 to copper relative to 100 parts by weight of synthetic resin selected from polyester, nylon, acrylic, polypropylene, or a mixture thereof. 3 to 13% by weight of conductive fiber yarn dispersed 5 parts by weight; copper filament forming a center 2 to 12% by weight of copper fiber yarns, the surface of which is selected from cotton fibers, wool fibers, polyester fibers, nylon fibers, acrylic fibers or blended fibers thereof, and the remaining amount of cotton yarns, polyester yarns, and their Disclosed is a woven pad including any one of ordinary yarns selected from the group consisting of blended yarns, and the gannetite fiber, conductive fiber yarn, and copper fiber yarn are joined together as a single twisted yarn. In addition to the increase in the manufacturing cost of the antimicrobial activity was also not satisfactory.

Accordingly, the present inventors have invented a silver nano-treated bed sheet and a method of treating the same to solve the above problems and filed it with a patent application No. 2005-0000383.

However, the silver nano-treated bed sheet is composed of an absorbent layer of absorbent quick-drying absorbing moisture and a waterproof layer of polyester which prevents the exudation of moisture, and both layers are fused by heat to produce public, such as hospitals, nursing homes and hotels. The demanding repeated washing conditions of the facility are weak, and the waterproofing layer is damaged even after tens of washings.

Accordingly, an object of the present invention is to provide a bed sheet that can be used more permanently by improving the durability of the laundry on the bed sheet having an antimicrobial activity as well as absorbency and waterproofness to solve the above problems. will be.
