Sanitary napkins generally consist of the surface layer, absorption layer and the bottom three parts, which are mainly considered from the materials and functions of these three parts.
(1) the surface of the sanitary napkins should be selected for the dry and open surface funnel type: the surface dry and cool can make the local skin not suffer from moisture;Funnel type design is superior to bucket design, and infiltration of liquid is not easy to return.
There are pure cotton and PE mesh materials.
(2) the middle to use breathable and high effective gel layer for good: sanitary napkin with high effective gel layer, can condense into compulsive the infiltrating liquid to jelly, not flow back after pressing, and you won't feel sticky on the surface.
The middle layer is made of paper pulp or silica gel
(3) is better to choose breathable materials for the bottom: it can make the gas water molecules pass, so, reach the role of moisture in time, effectively reduce wetness sanitary napkin and body, effectively reduce wetness and sultriness between sanitary napkin and body, keep dry and pure and fresh feeling.
The main constituent material of sanitary towel
PE perforation film:
Commonly known as "dry net surface", it is composed of PE film and special micropore, which can make the menstrual blood not easy to get back and keep the front of the membrane dry.
Macromolecule composite paper:
Polymer composite paper is a polymer of cotton, non-woven fabric and paper pulp, which is used to absorb the menstrual blood.
After bleaching, extraction of organic solvents and other operations of wood pulp, straw pulp.
The sanitary napkin containing the high efficient micellation layer can coagulate the infiltrated liquid into a gel. After compression, it does not return to the seepage. The surface is not sticky, and the material used is the polymer resin.
With special polyethylene (PE) plastic film as the base material, a crosslinked acrylic acid tree ester as adhesive, and then several special auxiliaries to process, waterproof breathable.
Hot melt adhesive:
Polyamide hot melt adhesive is base of polyamide resin.Polyamide resin is a linear thermoplastic resin with many repeated amide groups on the main chain of molecules.Compared with other thermoplastic resins, it has a remarkable characteristic that when it is heated and cooled, the melting and curing of the resin occur within a narrow range of temperature.This characteristic makes the polyamide hot melt glue in the construction, after heating molten coating a little cooling can quickly solidify;It can also make it close to the softening point of temperature and still have good adhesion performance.Because of hydrogen on amide groups of polyamide resin, with another amide groups on the chain segment to electronic carbonyl combined into strong hydrogen bond, the higher melting point of the resin, which has good flexibility, oil resistance and bonding performance.
From the type of paper:
The off-type paper is also called "silicone" paper, or anti-sticky paper.There are three layers of structure, the first layer of paper, the second layer is the film, and the third layer is silicone oil.Function:
(1) gelatine (gelatine) silicone paper
High temperature resistant, moisture resistant, oil proof, generally used in food industry packaging
(2) ordinary off-type paper:
Moistureproof, oil proof, play the segregation of product
The components and properties of sanitary napkins
Sanitary napkin in the process of development gradually evolved out of the product, from sanitary towel body both sides such as wing was born two pieces of stretch body, can have the effect of fixed sanitary napkin, may help prevent blood sliding sideways.
Fan-shaped tail fin:
The end of the sanitary towel has a fan structure, which can effectively prevent the leakage.
Can make the gas water molecules pass, so, reach the role of moisture in time, effectively reduce the effect of sanitary napkin and body moisture, effectively reduce wetness and sultriness between sanitary napkin and body, keep dry and pure and fresh feeling.
Arc line design, make the sanitary towel close to the body, more secure.Anti-leakage ability:
When the two sides of the crotch are pressed, the sanitary towel is compressed into the middle of the original half, the sanitary towel is still no side leakage;If there are concave anti fold line, can prevent the sanitary napkin crease, reduce the chance of side leakage.
Special structure of some sanitary napkins
KMS refreshing factor: KMS healthy recipe is contain menthol, cordate houttuynia, secrete tai, and so on Chinese and western medicine composition by zhongshan medical center and JingXing business development co., LTD. Jointly developed a care formula, these ingredients are anti-inflammatory, detoxification, the effect of heat, so to scent of pomegranate orchid fragrance.Fresh and refreshing when used.Cool and comfortable feeling.You can also neutralize the odor of menstrual blood.This kind of cooling is different from the cold that needs to be avoided during menstruation, so to some extent it inhibits bacterial proliferation and also improves the body's resistance!
Absorber back to 鍖?miao "V" choke uplift and a small cushion of flexible, elastic, soft joint hips in the center of the concave and convex curve, timely stop after flowing through the blood.
Natural stereo elastic protection, can effectively block the menstrual blood, even though the amount of days, also will give you a full range of peace of mind.In the center of the body, the newly added rapid infiltration absorber can absorb all the menstrual blood without recirculation in one second.With complete flexibility, no matter how you move, you will be glued to your body. There is no gap and no worries about leakage.
Instantaneous jie series of unique pioneering magic embossing and breakthrough of the absorptive layer, the absorption rate of two times, can make blood coming into contact with the skin instantly through the surface and absorbing layer is absorbed by efficient absorbent particles AGM molecules rapidly and condenses into gel locked tightly, almost does not flow back.
The newly improved "undistorted absorber" in the center of the body is elastic and can recover quickly after compression.There are double grooveways to support the whole absorber, which is not deformed by prolonged or repeated compression.
The front is evenly distributed large and deep open hole, and dissipated sulking.The back adopts the super - gas breathing film, breathes moisture.
The ultrathin design of the body, more breathable, can give a person relaxed feeling.
Like the wall, the general and the towel body in a certain Angle stand on the sides of the towel body, can help prevent the fluid from the side outflow.
Anion chip can release the average concentration of up to 6000 / cm3 negative ions, negative ions can promote the body enzyme and peculiar smell gas molecules and transformation, so as to improve human self-cleaning ability, the effect of removing odor, effective bacteriostasis.
Silver ion through free movement and breathable absorption, feel fresh and moist, remove odour, 5 seconds working, without damaging the physiological balance, without any stimulation.With the skin soft and soft paste, form a skin care, moisturizing, skin care layer.
Silver ions when in contact with the bacteria, called with the negatively charged active enzyme in coulomb attraction and strong adsorption, and the activity of enzyme protein gene - SH, - NH, which damage cells synthetase activity, prevent cell metabolism, intervention bacteria micro-organisms DNA synthesis, make the loss of division of reproductive capacity and death.
