Description

[Technical field]

[0001] The present invention relates to a pad, and more particularly to a pad for use on the human body. [Background technology]

[0002] In addition to pregnancy, childbirth, and menopause, the congenital structure of the urinary tract makes women susceptible to urinary incontinence.

[0003] Women who have problems with urinary incontinence often use sanitary pads to prevent their underwear from getting wet.

[0004] For example, Patent Document 1 discloses an absorbent article, which includes a top sheet material, a back sheet material, and an absorbent disposed between the top sheet material and the back sheet material. Both the center area and the side area of ​​the top sheet material have lattice-shaped recesses and protrusions. Although the absorbent article can absorb leaked urine, the problem of urine leakage still brings inconvenience to daily life.

[0005] Meanwhile, problems related to prostate enlargement due to tissue proliferation with age are very common in men.

[0006] In addition, modern people tend to sit too long and are constipated, which causes the blood vessels around the anus to become congested, reducing venous return and increasing the likelihood of developing hemorrhoids.

[0007] Furthermore, patients who are bedridden for long periods of time may develop bed sores due to pressure on the skin and poor circulation.

[0008] These symptoms can cause long-term suffering for patients and can adversely affect their daily lives.

[0009] These diseases are caused by poor blood circulation or muscle relaxation in the tissues around the pelvic cavity, and relieving the discomfort caused by the above diseases is a problem to be solved. [Prior art documents] [Patent documents]

Indeed, the present invention is in no way limited to the methods and materials described.

[0018] The pad of the present invention is a pad to be used on the human body, and includes a sheet member 1 as shown in FIGS.

[0019] The pad of the present invention is primarily used around the pelvic cavity of the human body or placed inside underwear pants, so that the sheet body 1 can be in direct and intimate contact with the skin.

[0020] The sheet body 1 includes a first surface 101 and a second surface 102 that is the opposite surface to the first surface 101, and has a plurality of fibers 11. That is, the first surface 101 and the second surface 102 are on opposite sides to each other.

[0021] In this embodiment, the sheet body 1 is a woven or knitted fabric obtained by spinning and weaving a plurality of fibers 11.

[0022] In another embodiment, the sheet body 1 may be a nonwoven fabric formed by directly bonding the plurality of fibers 11 under high pressure without spinning the fibers 11. In the case of a nonwoven fabric, the plurality of fibers 11 are arranged randomly.

[0023] The shape, size and thickness of the sheet body 1 can be selected according to the part of the human body to be used and the size of the wound, and therefore the present invention does not limit the shape, size and thickness of the sheet body 1.

[0024] Each fiber 11 has a polymer matrix 111 , a plurality of pyroelectric materials 112 distributed in the polymer matrix 111 , and a plurality of coupling agents (not shown) distributed in the polymer matrix 111 .

[0025] In this embodiment, the polymer matrix 111 is an aliphatic polyamide, and the aliphatic polyamide is Nylon 6 (polycaprolactam), which is polar.

[0026] In this embodiment, solid particles of polymerized nylon 6 and powdered pyroelectric material 112 are uniformly mixed in the solid state, and then melt spun in a screw spinning machine 9 to produce a plurality of fibers 11.

[0027] With the weight of each fiber 11 being 100 wt %, the content of the pyroelectric material 112 in each fiber 11 is within the range of 1 wt % to 3 wt %.

[0028] The pyroelectric material 112 in each fiber 11 includes kaolin, forsterite (main component is Mg2SiO4), and bakuhanseki.

[0029] In this embodiment, the weight of each fiber 11 is 100 wt%, the content of the pyroelectric material 112 in each fiber 11 is 1.8 wt%, and the pyroelectric material 112 in each fiber 11 includes kaolin, forsterite, baifan stone, montmorillonite, and tourmaline, and the total weight of the pyroelectric material 112 in each fiber 11 is 100 wt%, the content of kaolin is 50 wt%, the content of forsterite is 20 wt%, the content of baifan stone is 10 wt%, the content of montmorillonite is 10 wt%, and the content of tourmaline is 10 wt%.

[0030] Each pyroelectric material 112 can be a powder, fine flakes or fine particles, and the average surface width or average particle size of each pyroelectric material 112 is 1 μm.

[0031] In this embodiment, the polymer matrix 111 and the plurality of pyroelectric materials 112 are inherently polarized and are further polarized by the high voltage electric field 91 .

[0032] In this embodiment, the polymer substrate 111 and the plurality of pyroelectric materials 112 all have a pyroelectric effect and therefore release a negative charge when heated.

[0033] The plurality of pyroelectric materials 112 have a peak at 1460 cm in the infrared spectrum. -1 , 1165cm -1 , 1090cm -1 , 968cm -1 and 720cm -1 It has an infrared absorption peak.

[0034] In this embodiment, the polymer substrate 111 is nylon 6, which belongs to the highly crystalline linear polymer, and has a peak at 720 cm -1 ~980cm -1 Since nylon 6 has an infrared absorption peak in the range of 0.1 to 1.0 mm, it has polar amide groups (CO-NH) in its molecular chains, and hydrogen bonds are formed between the molecular chains, giving it a dipole moment. When it is polarized by a high-voltage electric field 91, the strength of the dipole moment can be increased.

[0035] In other embodiments, the polymer substrate 111 may employ polyethylene terephthalate (PET) or polypropylene (PP).

[0036] Figure 4 is a Fourier transform infrared spectroscopy (FTIR) spectrum of kaolin, Figure 5 is a Fourier transform infrared spectroscopy spectrum of forsterite, Figure 6 is a Fourier transform infrared spectroscopy spectrum of bakufanseki, Figure 7 is a Fourier transform infrared spectroscopy spectrum of montmorillonite, and Figure 8 is a Fourier transform infrared spectroscopy spectrum of tourmaline.

[0037] As shown in Figs. 4 to 8, in the infrared spectrum, kaolin and bakuhanseki have a peak at 1460 cm -1 and bakuhan stone has an infrared absorption peak of 1165 cm -1 The infrared absorption peaks of montmorillonite, bakufanseki and tourmaline are 1090 cm -1 and forsterite has an infrared absorption peak at 968 cm -1 and the infrared absorption peak of bakuhanseki and tourmaline is 720 cm -1 It has an infrared absorption peak.

[0038] The manufacturing process of the pad of the present invention will now be described.

[0039] First, the raw material of the pyroelectric material 112 (i.e., a mixture of kaolin, forsterite, bakufanseki, montmorillonite, and tourmaline) is pulverized in a pulverizer to obtain multiple coarse powders with an average surface width of 5 μm. Then, a magnetic separator is used to magnetically separate the powders at a magnetic flux density of 1.5 Tesla (T). The magnetically separated coarse powders are further pulverized in a fine pulverizer to obtain multiple fine powders (i.e., pyroelectric material 112) with an average surface width or average particle diameter of 1 μm. Then, a 1.2×10 8 After polarizing the fine powder in a high voltage electric field of 1000 V / m, the polarized fine powder is washed with water and finally dehydrated and dried.

[0041] Then, the dried fine powder (i.e., pyroelectric material 112) and the polymerized nylon 6 particles (i.e., polymer substrate 111) are mixed uniformly in a solid state, while a coupling agent is added and mixed. Since the dried fine powder and nylon 6 particles are mixed in a solid state, there is no influence of viscosity, and the uniformity of the mixture is improved.

[0042] Then, as shown in FIG. 3, the mixed pyroelectric material 112 and polymer substrate 111 are heated, melted, and spun in a screw spinning machine 9 to produce a plurality of fibers 11, each of which contains a plurality of pyroelectric materials 112 and a polymer substrate 111.

[0043] As shown in Figure 3, 3.0 × 10 6 V / m~7.0×10 6 By poling with a high-voltage electric field 91 of 7.0×10 V / m, the dipole moments of the multiple fibers 11 are regularly arranged parallel to the electric field direction, which increases the strength of the dipole moments to obtain a more pronounced hysteresis loop and increases the energy of discharging the charge. In this embodiment, the strength of the high-voltage electric field 91 is 7.0×10 6 V / m.

[0044] That is, the fibers 11 are melt spun and have a diameter of 7.0×10 6 It is a mixture of a solid polymer matrix 111 and a solid pyroelectric material 112 poled by a high voltage electric field 91 of 100 V / m.
