Abstract
Provided is a roll-shaped medical adhesive tape wherein an adhesive layer is formed on one surface of a support medium, which is rolled up into a roll shape. The support medium comprises a nonwoven fabric that is formed from synthetic resin fibers and has a thickness between 50 [mu]m and 200 [mu]m. Using thermic boring, recessed areas are formed in straight lines in the width direction, perpendicular to the direction the tape is rolled in, on the back surface of the support medium, said back surface being the side opposite the adhesive layer. The depth of the recessed areas is between 5% and 60% of the thickness of the support medium, and the spacing between the recessed areas is between 0.5 mm and 1.5 mm. The adhesive tape is rolled into a roll shape such that the adhesive layer contacts the back surface of the support medium.
Description
Technical field
The present invention relates to the web-like medical adhesive tape; In more detail; Relate to be that the medical adhesive tape of supporter is wound into web-like, tearing property of hands (character of tearing with hands), smooth tearing property (the horizontal tearing port of band is collinear probability), the good web-like medical adhesive tape of operability when wearing glove and manufacturing approach thereof not across release liner (being also referred to as " spacer ") with exoskeletal winding with the excellent non-woven fabrics of breathability and retractility.
Background technology
Medical adhesive tape is used for the protection of affected part and/or wound portion and gauze and/or absorbent cotton, conduit, pipe, compress etc. is fixed in skin surface.Usually, medical adhesive tape has the layer formation that is provided with adhesive phase in the one side that with paper, cloth, plastic foil etc. is the supporter of raw material.For example, the flexible vinyl chloride film is because obdurability, stress relaxation property, printing adaptability etc. are excellent and cheap, thus as the supporter of first aid rubber plaster by general.But such plastic foil is insufficient to the adaptability of skin surface, and flexibility, breathability are also insufficient.
Relative therewith, non-woven fabrics is because breathability is excellent and it is stuffy to be difficult for when pasting, thereby is suitable as the supporter of medical adhesive tape.And; In recent years having developed with polyurethane, polyester is the non-woven fabrics of the retractility of raw material; Through using these to have the supporter of the non-woven fabrics of retractility and breathability concurrently as adhesive tape; Thereby can obtain be difficult for to produce macule and/or itch, skin problem such as erythema and can follow the adhesive tape (for example, with reference to patent documentation 1 and 2) of motion of the skin of stickup.Be that the adhesive tape of supporter has as the excellent various characteristics (for example, with reference to patent documentation 3 and 4) of medical adhesive tape particularly with the excellent polyurethane non-woven fabrics of breathability and retractility.
Except above-mentioned various characteristics, the tearing property of hands that medical adhesive tape requires available hands to tear more.About giving adhesive tape, up to the present various report is arranged with tearing property of hands.Improve the example of tearing property of hands as punching on adhesive tape, for example, proposed on binding agent impregnation non-woven, to be provided with perforation or at least 1 direction, become the mode of row that the method (with reference to patent documentation 5 and 6) in hole is set with the end.
In addition, have pair non-woven fabrics to handle with chemical adhesive, thus be provided with incomplete perforation pattern and the instance (with reference to patent documentation 7) of adhesive tape.It can be the pit condition that does not connect that patent documentation 6 has also been put down in writing the hole.
But supporter is that the adhesive tape of non-woven fabrics generally is difficult to tear with hands, even can tear by enough handss, also exists and how to be torn such problem with the irregular state of its tear face (tearing the state of end irregularity).In addition, if on supporter, open perforation, then be difficult to keep the intensity of bonding sheet itself.If with processing non-woven fabrics such as chemical adhesives, then produce the such problem of function, feel that adhesive tape can not utilize non-woven fabrics for the intensity that improves bonding sheet.
On the other hand, have through being that the non-woven fabrics of 0.5～5mm carries out coinging and forms continuously or the depressed part of discontinuous pattern to thickness, thereby improve the instance (with reference to patent documentation 8) of tearing property of hands.This adhesive tape is applied to purposes such as cleaning, the cooking, wiping brush, and is different with the medical adhesive tape technical field, and can not realize that in coinging thickness is desired the tearing property of hands of medical adhesive tape, the smooth tearing property about 50～200 μ m.

The specific embodiment
Web-like medical adhesive tape of the present invention (following only be called sometimes " adhesive tape ") has adhesive layer on the one side at least supporter.This supporter is made up of non-woven fabrics.
Below the preferred implementation of non-woven fabrics of the present invention is described.
It is that 1～20mm, fineness are that the fiber at 1～30 dawn is made that the non-woven fabrics that uses in the adhesive tape of the present invention is to use fiber length.Less than 1mm, the intensity when then forming the sheet of non-woven fabrics is low, grows up in 20mm like fruit fiber like fruit fiber length, and it is many that then interfibrous binding site becomes, the reduction of tearing property of hands.If fineness is less than 1 dawn, then the stiffness of non-woven fabrics is low and operability worsens, if greater than 30 dawn then stiffness becomes really up to the mark, thereby sometimes adhesive tape sticking sense of discomfort when the human body is become big.The weight per unit area of preferred non-woven fabrics is 20～60g/m
2, its thickness is 50～200 μ m.As employed fiber,,, for example can enumerate polyolefin such as polyethylene, polypropylene, PET polyester such as (PET), nylon, polyurethane etc. as its material so long as the synthetic fibers that have the character of heat fusing get final product.Soft in order for example to make, can cooperate wood pulp etc. with arbitrary ratio in these fibers.Under the situation that cooperates wood pulp, preferred synthetic fibers: the ratio of wood pulp is in the scope of 99: 1～70: 30 (weight ratio).
If in adhesive tape of the present invention, use the non-woven fabrics that becomes the net method for making to make through vertical with the horizontal orientation uniform airflow that can make fiber, then can the fiber appropriateness be cut off through hot piercing, tearing property of adversary is favourable.But,, also can use the non-woven fabrics of making through other method for makings as long as fiber, non-woven fabrics satisfy above-mentioned condition.On the other hand, as spun-bonded non-woven fabrics, the non-woven fabrics of making through the infinitely-great in fact method for making of the length that makes fiber since can be through hot piercing appropriate cut staple, so not preferred.
Preferred its weight per unit area of non-woven fabrics of the present invention is 20～60g/m
2, 30～50g/m more preferably
2If weight per unit area is less than 20g/m
2, then operability worsens because the stiffness of non-woven fabrics reduces.If weight per unit area is greater than 60g/m
2, then fiber hot adhesion point each other increases, and it is strong that non-woven fabrics becomes, and tends to the reduction of tearing property of hands.
Preferred its thickness of non-woven fabrics of the present invention is 50～200 μ m, more preferably 80～150 μ m.If thickness, then constitutes the fiber spacing of non-woven fabrics less than 50 μ m from shortening, interfibrous hot adhesion point increases, and it is strong that non-woven fabrics becomes, sometimes the reduction of tearing property of hands.On the other hand, if thickness, then constitutes the fiber spacing of non-woven fabrics greater than 200 μ m from elongated, interfibrous hot adhesion point excessively reduces, and non-woven fabrics tends to die down.The thickness of non-woven fabrics is measured under the pressure status that non-woven fabrics is applied 1kPa according to the JIS L of Japanese Industrial Standards 1096.
Through the non-woven fabrics that uses among the present invention is processed according to the hot piercing that the continuous pattern that is essentially linearity does not connect non-woven fabrics,, tears along straight line easily non-woven fabrics thereby being become.Through the degree of control hot piercing, can control tearing property of hands.The degree of depth of each depressed part that forms through hot piercing is not necessarily wanted evenly, but need be with respect to the thickness of non-woven fabrics in 5～60% scope.If the degree of depth is arranged greater than 60% depressed part, then the tensile strength of adhesive tape significantly reduces, if the depressed part of degree of depth less than 5% is arranged, then is difficult to give tearing property of hands.The degree of depth of perforation is meant the degree of depth apart from the depressed part of non-woven fabrics supporting body surface before the hot piercing.The degree of depth of depressed part is passed through the coiling direction of medical adhesive tape along band cut off, and the photo of the section of shooting depressed part is measured.
Through the scope that is spaced apart 0.5～1.5mm that each depressed part that forms is processed in hot piercing, be preferably the scope of 0.7～1.3mm.If the gap of each depressed part greater than 1.5mm, needs to confirm, selects to tear the position when then hands tears sometimes.If the gap of each depressed part is less than 0.5mm, then adjacent perforation interferes with each other, thereby possibly cross over a plurality of perforation when hands tears and to tear tearing port crooked.Consider from the viewpoint of tearing property of hands, the interval of each depressed part preferably along the coiling direction of band for all uniformly-spaced.The deepest part that the interval of each depressed part is meant adjacent depressed part is each other along the distance of the coiling direction of band.
