Question 2: If fluff pulp is not used for sanitary napkins, what should be used instead? Fluff pulp, as the material of most sanitary napkins, not only has good water absorption, but also has low price. It's not that our country can't make safe and healthy sanitary napkins, but that manufacturers deliberately lower costs and make more profits. Just like the millet that has been on fire in recent years, it is a truth that the same configuration is much cheaper.
Now more and more people know the harm of fluff pulp. Unfortunately, there are not many products without fluff pulp on the market, and Dior women's wear is one of them. Let's take a look at the structure of fluff pulp-free sanitary napkins:
Fluff pulp-free, fluorescent and odorless negative ion sanitary napkins can be found in Baidu.
Question 3: What brand of sanitary napkins are not as many as those in fluff pulp, and Philippine pattern is one of them.
Question 4: What is the difference between sanitary napkins with fluff pulp and those without fluff pulp? Fluff pulp is not well absorbed and easily deformed.
Question 5: How to tell that sanitary napkins contain fluff pulp 1? Allergy: The lower the better.
Mesh: As a daily product in close contact with skin (especially thin and sensitive skin parts), the top layer of menstrual towel, that is, mesh, is mainly responsible for sensitization. There are two kinds of mesh surface: 1) cotton mesh surface, which is made of spunlaced non-woven fabric, which is softer and less allergic; 2) Perforated membrane, also known as dry mesh surface. It is made of polyethylene film with small holes, which is more likely to cause allergies. No matter whether it is the mesh surface or the basement membrane (cast film), there should be no peculiar smell, color spots or miscellaneous spots. Try to choose pure natural mesh materials, such as bamboo fiber and cotton.
Essence: Some products like to add essence to attract women's favor. Whether it is natural essence or artificial essence, it will increase the sensitization of products. Therefore, the safety probability of choosing fragrance-free is higher.
Second, the seepage velocity: the sooner the better.
Obviously, the faster the liquid is absorbed by the menstrual towel, the more comfortable the skin will feel. This absorption rate is also the seepage velocity of liquid. Infiltration is completed through a series of structures, so it will naturally be affected by many factors.
Test method: pour the same amount of normal saline on the net surface, record the time, and the fastest penetration is better.
Mesh material: the cotton mesh is very loose and the liquid permeates quickly. The dry net itself is a waterproof material. After the liquid enters the lower layer through the small hole, it is not easy to flow back, so the skin will feel dry.
Diversion groove: after the liquid reaches the net surface, it is first evacuated in all directions of the plane by the concave diversion groove. The depth of diversion groove and the rationality of groove distribution will affect the diversion speed.
Guide bar: after the liquid passes through the surface layer, it needs a layer of guide bar, which is a non-woven fabric with long fibers. Through capillary action, the liquid quickly diffuses along the fiber and continues to penetrate deeper. Not-so-good menstrual towels generally don't notice this detail.
Diameter and length of absorbent cotton core fiber: The main material of menstrual towel core is "cotton core", which is actually not cotton, but pulp fiber-lignocellulose. This is a special kind of pulp, which is made of softwood by chemical bleaching, so it belongs to "chemically bleached softwood pulp" and is mainly used for sanitary products. The fiber is long and soft, with high hygienic grade, which is called fluff pulp (fluffy.
Pulp). Due to the lack of wood in China, it mainly relies on North America (the United States and Canada, mainly international paper industry, etc. ) and northern Europe (Finland and Sweden, mainly Stora)
Enso) import. European cork fiber is thinner and longer, with less elasticity, but it also has better air permeability. Pines in North America grow faster, have thicker fibers, are less breathable, and are more elastic. As a representative of the United States, Hu used North American softwood pulp.
Particle size and mixing uniformity of water-absorbing beads: Water-absorbing beads mixed with "cotton core" are the most commonly used. In fact, they have a special name: SAP.
Polymer), whose main component is polypropylene cross-linked resin, can absorb 500 to 1000 times of its own water (its absorption capacity is affected by the osmotic pressure of liquid, and the amount absorbed by SAP will be greatly reduced, and human hematopoiesis or physiological saline will be used instead when actually testing the water absorption). Water-absorbing beads should be evenly mixed with fibers, and the particle size should not be too fine, otherwise they will partially absorb water and expand rapidly, preventing water from infiltrating into deeper channels. Test method: when pouring a glass of water, a big pimple appears on the surface of the menstrual towel, mostly because of uneven stirring.
Third, water absorption capacity: the bigger the better.
The absorbent capacity of the menstrual towel depends on the absorbent beads and fibers. There is a lot of knowledge in it.
Source of water-absorbing beads: Water-absorbing beads are mainly produced in the United States, South Korea, Japan and Singapore. The main manufacturer in Japan and Singapore is Sumitomo Corporation.
Seika) is the SAP with the strongest absorption capacity, followed by the United States and the weakest in South Korea. As far as I can see before, Sumitomo's sap is spherical after absorbing water, while that of the United States and South Korea is irregular polyhedron. I don't know what the situation is now. Japanese brands generally use Sumitomo. The adsorption beads have strong adsorption capacity, so the product can be made thinner.
Fourth, permeability: the lower the better.
Can the water-absorbing beads lock the water firmly after absorbing water? Under a certain extrusion pressure, infiltration will occur, and high infiltration will certainly be uncomfortable. It also needs a reasonable ratio of water-absorbing beads to slurry to reduce permeability.
Test method: after pouring a certain amount of physiological saline, put the filter paper on the surface of the menstrual towel to see how much liquid it will absorb. & gt
Question 6: Which brands of sanitary napkins do not contain fluff pulp and fluff pulp?
Question 7: Do you know what fluff pulp is in sanitary napkins? High-grade sanitary napkins are made of wood pulp, polymer, puffed paper, absorbent paper and other materials.
Ha ha. . However, there is a difference between ordinary raw materials and high-grade raw materials. The raw materials of high-grade sanitary napkins are generally imported with good materials. . . .
Sanitary napkins are made of fluff pulp (pulp), not cotton.
Question 8: What sanitary napkin does not contain fluff pulp and fluorescent agent? The sanitary towel does not contain fluff pulp and fluorescent agent. Swiss sgs test certificate.
Question 9: It is said that fluff pulp is bad for health, but there is fluff pulp in sanitary napkins on the market. Isn't it necessary? It's not what the landlord said. Sanitary napkins on the market are all made in fluff pulp. 90% sanitary napkins on the market contain fluff pulp. Although it is not accurate to say whether fluff pulp is harmful to human body, recycled bleached materials will not be clean. Even if you don't see any harm now, it will be too late to regret it after a long time. I know that Ms Dior's negative ion sanitary napkin contains no fluff pulp ingredients. The landlord can Baidu it.
Question 10: There is no fluorescent agent on the market at present. What brand of sanitary napkins do you have that do not contain fluff pulp? 10, …Cocolady sanitary napkin is a new product of Dada, with three patent numbers of,, and Ping An Insurance Company. The packaging is disinfection grade, with strong water absorption and patented side leakage prevention. Passed the FDA food certification, more than 90% antibacterial. Many advertisements for sanitary napkins in the market are well publicized, but there are no patents. Cocolady's patent number is printed on the package, including two packages for daily use, one for night use and one for delayed use.
