Definitions
- the present invention relates to a nonwoven fabric and a patch having excellent water absorption. More specifically, the present invention relates to a water-absorbent nonwoven fabric and a patch suitable for use in contact with the human body, which has excellent adhesion to the human body when water swells and has little physical irritation to the human body.
- water-absorbing fibers have been developed in many fields such as water-stopping materials and building materials, as well as hygiene materials and adhesive materials. Among these uses, it is used to prevent stuffiness caused by sweat, etc., particularly by utilizing the characteristics of water-absorbing fibers, for use in the human body such as sanitary materials and patch materials (see Patent Document 1, for example). Or known as a blood-absorbing material (see, for example, Patent Document 2).
- These hygiene materials and patch materials use water-absorbing fibers to absorb body fluid that flows out from the human body, and do not supply moisture or medicinal ingredients to the skin. Generally used for the human body. For this reason, there was no particular problem with the irritation that the water-absorbing fibers had on the skin or the adhesion to the skin.
- Patent Document 1 Japanese Patent Laid-Open No. 6-207358
- Patent Document 2 Japanese Patent Laid-Open No. 2001-120588
- a water absorbent fiber contains a medicinal ingredient and is brought into contact with the skin to actively supply the active ingredient to the skin.
- a nonwoven fabric containing a water absorbent fiber and a low-temperature shrinkable fiber is used.
- a poultice material is disclosed (for example, see Patent Document 3). The caulking poultice does not require an adhesive, prevents skin irritation, and effectively supplies active ingredients to the skin.
- the short fiber nonwoven fabric made of water-absorbing fibers containing moisture is in direct contact with the skin, the fiber ends will irritate the skin, giving it a strong discomfort, and further damaging the skin. Problems with the use of.
- the swollen water-absorbing nonwoven fabric has the problem that the unevenness with poor adhesion to the skin is large, and the location and movement are intense.
- water-absorbing fibers containing moisture are easy to adhere to the skin, when the non-woven fabric is peeled off, many fiber pieces are detached and remain on the skin. Become.
- Patent Document 3 Japanese Patent Laid-Open No. 7-32640
- the present invention provides a water-absorbing short fiber nonwoven fabric that has little irritation to the skin, excellent adhesion to the human body, and hardly breaks even when it is directly brought into contact with the skin by containing moisture or medicinal ingredients. It is intended to provide.
- the present invention employs the following means in order to solve the problem.
- the water-absorbent short fiber nonwoven fabric according to the present invention has excellent irritation to the skin, moisture, and close contact with the human body, so that it can be used in sensitive areas, areas with large irregularities, and areas where movement is intense. It can be brought into contact with the skin without using an adhesive, etc., and it can supply moisture and medicinal ingredients directly and effectively to the skin. Have.
- the adhesive fiber used in the present invention is preferably 0.5 to 2.7 dtex. 2. If it is 7 dtex or more, the fiber end strongly stimulates the skin, causing discomfort to the user, and may also damage the skin. On the other hand, if it is less than 0.5dtex, it can be used as a patch and move This is because when the fibers are partially broken and the skin strength is peeled off, the non-woven fabric pieces will cause problems such as fiber pieces remaining on the skin. More preferably, it is 0.8 to 2.5 dtex, and most preferably 1.0 to 2. Odtex.
- the water absorbent fiber used in the present invention preferably has a water absorption rate of 200% or more. This is because, within such a range, moisture and medicinal components can be sufficiently contained, and adhesion to the skin can be maintained for a long time. Particularly preferred is 1000% or more, and even more preferred is 10000% or more.
- the medicinal ingredients referred to in the present invention include those used for cosmetics such as keeping healthy skin in addition to those having a health restoring action such as healing of stiff shoulders and sprains.
- the water-absorbing fiber used in the present invention is not particularly limited as long as it satisfies the fineness and water absorption rate described above, but the water-absorbing fiber has a COOX (X: alkali metal or NH) group.
- the water-absorbing short fiber nonwoven fabric according to the present invention preferably contains 40% to 95% by weight of water-absorbing fibers. If it is less than 40% by weight, water and medicinal components cannot be sufficiently retained, and further, the adhesion to the skin becomes insufficient and the film is easily peeled off. On the other hand, if it is 95% by weight or more, it becomes difficult to maintain the strength of the nonwoven fabric, and the nonwoven fabric breaks when moved during use, and the nonwoven fabric piece remains on the skin when peeled off.
- the water-absorbing fiber content is 60 wt% to 80 wt%, most preferably 65 wt% to 75 wt%.
- the water-absorbent short fiber nonwoven fabric useful in the present invention has a basis weight of 5 to LOOg Zm 2 before containing water. If the basis weight is less than 5 gZm 2 , the water 'medicinal component cannot be sufficiently retained. Further, if the basis weight is lOOgZm 2 or more, the adhesion to the skin is lowered, and it becomes difficult to use it in a portion having large irregularities or a place where movement is intense. A more preferred basis weight is 10 to 50 gZm 2 , most preferably 15 to 35 gZm 2 .
- the water-absorbing short fiber nonwoven fabric according to the present invention preferably contains an adhesive fiber.
- Short fiber non-woven fabrics such as water-absorbent fibers tend to break when swollen, and can be used for needle punching, etc. This is because according to the fiber entanglement, the nonwoven fabric's fibers break into pieces when attached to the skin and become difficult to remove when exercising in the used state.
- the content of the adhesive fiber is preferably 5 to 60% by weight, more preferably 10 to 50% by weight, and most preferably 25 to 35% by weight.
- the adhesive fiber used in the present invention may be a fiber having a composite fiber (such as a seascore structure) such as PETZPP, PPZPE, PET / PE, PET / PET, PEZPE, and PPZPP.
- a composite fiber such as a seascore structure
- PETZPP polyolefin fibers are preferred because they are highly flexible and have a low irritation on the skin.
- the embossing pattern and conditions of the heat roller are not particularly limited, but the embossed area ratio is preferably 20% to 100%! /. If the embossed area is less than 20%, the fiber piece that remains on the skin will increase. More preferably, it is 50% or more, and most preferably 100% (flat roller).
- the heating conditions with the heat roller should be 10 ° C to 20 ° C higher than the melting point of the adhesive fiber (low melting point component) and the linear pressure should be 10 to 150kg / 2.5m. Is recommended. If the linear pressure is less than 10kg / 2.5m, the short fiber nonwoven fabric containing water will be easily disassembled when the external action is applied during exercise, etc. This is because the problem of adhesion occurs. In addition, when the normal short fiber nonwoven fabric has a linear pressure that is too high, the texture becomes hard and paper-like problems occur. Short fiber nonwoven fabric containing water-absorbing fibers has a linear pressure in a swollen state. The effect on the texture is small, and the upper limit is not particularly problematic.
- the short fiber nonwoven fabric according to the present invention is particularly effective for use in contact with the human body, and can be used for a patch, a poultice material, a cosmetic material, and the like.
- Nonwoven fabric break Select 5 female monitors, swell the sample 15cm X 15cm well with lotion, put it on the waist, leave it for 1 hour, peel off the sample and leave the non-woven fabric piece (gel-like material) on the skin ) was observed and evaluated according to the following criteria.
- the water-absorbing short fiber nonwoven fabric according to the present invention (Examples 1 and 2) is a water-absorbing fiber that has low skin irritation and excellent adhesion, and further, short fiber pieces hardly remain on the skin. It was.
- the water-absorbing short fiber non-woven fabric outside the scope of the present invention has problems such as large skin irritation, poor adhesion, or short fiber fragments remaining on the skin, and is difficult for practical use. .
- the present invention uses a moisture or medicinal component directly in contact with the skin, has little irritation to the skin and excellent adhesion to the human body, and further, the nonwoven fabric is used without breaking and separating. Therefore, it can be used for adhesives, poultices, cosmetics, etc., regardless of the location of the human body, such as joints, soles of the face, and the face, contributing greatly to the industry.
