The core safety issue of proof period underwears' "hygiene" status is being repeatedly ignored by people. Some experts worry that "Proof period underwears are sometimes simply a bacterial bomb carried by women, which can cause a mild or severe disease at any time."

How to "see" the pros and cons of proof period underwears

   In fact, the state has always attached great importance to the quality of proof period underwears. In addition to formulating relevant industry standards, it has also conducted multiple supervision and random inspections. However, these standards only stipulate the proof period underwear production environment and product sanitary quality standards. There are no strict sanitary requirements for the raw materials and auxiliary materials used in the production of proof period underwears. In addition, the "secondary pollution" caused by improper use by consumers, "health" "The threat is still there from time to time around women. Therefore, a comprehensive "standard" protection and the improvement of consumers' self-protection awareness have become very important in this "big palm".

   "Wife lovers" invented proof period underwears

   In 1550 BC, there have been records of putting soft cloths into women’s vaginas to prevent pregnancy. Experts infer that these soft cloths are also used to cope with menstruation, which is probably the first generation of “proof period underwears” we can know.

The modern version of proof period underwears is said to have been invented by an American man who loves his wife very much. He accidentally discovered that clean cotton fibers and absorbent pulp were wrapped in a soft cloth to make a long strip of cotton pad. It can effectively alleviate the pain and inconvenience of the wife during menstrual period. This cotton pad became popular from European and American countries in the 1940s, and gradually developed to be made of disposable materials.

   Manufacturers vary in good and bad

   Since entering the Chinese market in the 1980s, proof period underwears have been quickly accepted by female consumers due to their convenience and ease of use. According to statistics from authoritative departments, there are about 340 million women in the age group that need to use proof period underwears in my country. At the same time, proof period underwears are a relatively stable one-time sanitary product for daily use. There is no difference between off-season and peak season. The consumer market has caused fierce competition among manufacturers. At present, my country has more than 1,000 proof period underwear production plants and nearly 1,400 production lines.

   Due to the difference in price positioning, my country's proof period underwear market is naturally divided into two camps, domestic and international brands. Statistics from the Household Paper Professional Committee of the China Paper Association show that, from the perspective of overall sales across the country, the sales of domestic brands are currently ahead of the international brands, but the domestic brands of proof period underwears are relatively stray, with hundreds of manufacturers producing scales They are of different sizes, and only a few are truly famous and have larger sales.

   In order to be able to take a share of the huge market profits, many manufacturers have made a big fuss on the characteristics of their proof period underwear products. Such as "green", "three-dimensional enclosure", "slim", "silk thin", "dazzling color" and other novel "exclusive concepts" emerge one after another, but these "concepts" are empty shouting gimmicks or really worthy of the name. However, not all of them have been inspected and certified by the relevant departments.

In addition to these numerous names, proof period underwears can be divided into three types according to the shape and structure: no wing type, wing type, and sanitary pad, including various special designs of "lengthening and widening"; according to the surface material, it can be divided into dry mesh surface It can be divided into three categories: ordinary grade, disinfection grade and antibacterial effect according to the hygienic microbiological characteristics.

   The right choice is good

There are more and more brands of proof period underwears in the market, and the advertisements are overwhelming. How to choose the sanitary products that are both affordable and suitable for you? Gynecologists "informed" the majority of female consumers: choosing proof period underwears should be based on time, occupation, place, Factors such as clothes and physique are taken into consideration, and the most expensive is not necessarily the best.

Generally speaking, on the days with the most menstrual flow, you can use dry-mesh proof period underwears with daily-use wing-type proof period underwears (you can switch to cotton-net proof period underwears for people with allergies). Wing-shaped proof period underwears. When the menstrual volume starts to drop, you can switch to a slim proof period underwear for daily use. In the last one or two days of the menstrual period, although the menstrual blood is almost completely drained, there will be a small amount of bleeding. At this time, a thin sanitary pad is undoubtedly the most suitable, which can be changed at any time without soiling the clothes.

   Women's autoimmunity is reduced during menstruation, and they are particularly vulnerable to external bacteria. If the body's resistance is not strong, it is best to choose antibacterial proof period underwears. In addition, if the work requires frequent standing or walking, it is best to choose wing-type proof period underwears. If you need to go out frequently for work, it is recommended to choose high-quality thin, wing-type, or even night-use proof period underwears. If the lady who loves beauty wants to wear a skirt during the "period" period, she can use a thin or ultra-thin proof period underwear. People with allergies should use dry mesh and scented proof period underwears with caution. It is best to consult a doctor before using medicated proof period underwears.

   It has been reported that most domestic women are used to using proof period underwear pads (proof period underwears), thinking that the tampon needs to be directly inserted into the vagina when using the tampon, which feels inconvenient. In fact, whether you use proof period underwears or tampons, there are pros and cons, and you need to choose them according to your personal preference and physical condition. The most important thing to pay attention to when using proof period underwears is to change them frequently, usually every 3 hours, so as to avoid the accumulation of menstrual blood infiltration and easy to emit peculiar smell and infection of Candida albicans.

Are proof period underwears really getting safer?

   An official from the World Health Organization once stated that 50% of patients with gynecological diseases in the world have used unclean sanitary products. As early as 1996, a large-scale statistics in my country showed that 38% of women who use proof period underwears are sick. Although these figures do not directly explain the inevitable connection between proof period underwears and gynecological diseases, the fact that proof period underwears are not "hygiene" has indeed become a serious problem that both producers and users cannot avoid.

   However, the core safety issue of proof period underwears' "hygiene" status is being repeatedly ignored or even deliberately avoided. This is because women themselves find it difficult to express themselves and do not want to talk too much about the problems caused by this; men do not know what is wrong with this simple little thing because they do not understand it; although the producer knows it, it is very I have no choice but to mention it, because the problem of autogenous bacterial contamination when proof period underwears are used is a worldwide problem, and proof period underwears made of traditional raw and auxiliary materials cannot be solved at all.

   In fact, the state has always attached great importance to the quality of proof period underwears. In addition to formulating relevant industry standards, it has also conducted multiple supervision and random inspections. However, these standards only stipulate the proof period underwear production environment and product hygienic quality standards, and do not have strict sanitary requirements for the raw materials and auxiliary materials used in the production of proof period underwears, such as the packaging plastic bags of proof period underwears, and the paper printed matter in the bags. Such auxiliary products are not produced by proof period underwear manufacturers themselves, and they are not restricted by strict sanitary standards. There are many opportunities for bacterial contamination in the process of transportation, storage, and sales. As a result, even the products of first-class companies cannot guarantee that they will not be contaminated by raw materials containing harmful bacteria. In addition, some small companies import "foreign garbage" from foreign manufacturers in order to reduce costs, and use fluff pulp removed from waste diapers, diapers, and proof period underwears to produce proof period underwears, and sell them at an average 50% lower than those of regular manufacturers. When the price is put on the market, it is more difficult to guarantee the hygiene index.

   What is more worthy of consumers’ attention is that proof period underwears should be avoided as much as possible from "secondary pollution" during use. Human hands have a lot of bacteria. When opening the proof period underwear, try not to touch the surface of the proof period underwear with your hands. It is best to wash your hands before using it. Proof period underwears must be replaced in time during menstruation to prevent a large amount of menstrual blood from becoming a "hotbed" for the proliferation of microorganisms. It is best to buy individually packaged proof period underwears to prevent harmful bacteria in the air from being "taken advantage of."

  Inspection products have "marks" to follow

  According to the information provided by the National Paper Quality Supervision and Inspection Center, the performance indicators of proof period underwears implement the national standard gb8939-1999 "Proof period underwears (including sanitary pads)". The performance indicators required by the standard are mainly: deviation, permeability, water absorption rate, ph value, adhesive strength and delivery moisture, of which permeability and ph are mandatory clauses, and the rest are recommended indicators. The sanitary indicators of proof period underwears implement the mandatory national standard gb15979-2002 "Sanitary Standards for Disposable Sanitary Products". The required indicators are mainly: the total number of bacterial colonies, coliforms, pathogenic suppurative bacteria and fungal colonies.

   Sanitary indicators Sanitary indicators refer to the total number of bacterial colonies, coliforms, pathogenic pyogenic bacteria (including Staphylococcus aureus, Pseudomonas aeruginosa, and Streptococcus hemolyticus), and the total number of fungal colonies. Proof period underwear products are sanitary products, and unqualified sanitary indicators may directly endanger human health.

  Deviation Total length deviation, full width deviation, and bar quality deviation indicate the uniformity of the product. Products of the same specification should be uniform, and should not be different in length, width, or thickness, otherwise it will affect the use. The standard requires that the full-length deviation, full-width deviation, and bar quality deviation of qualified products are ±10%, ±10%, and ±20%, respectively.

  Permeability Permeability includes the amount of penetration and the width of the front lateral penetration, which indicates the absorption performance of the product and whether it is easy to use. The small infiltration amount and the large width of the front lateral infiltration indicate that the product has poor absorption performance. The liquid cannot be absorbed during use, and side leakage will occur, which will affect the use effect. The standard requirements for premium, first-class and qualified products are ≥3.9g, ≥2.9g and ≥1.9g respectively.

   water absorption rate Water absorption rate is also an indicator of absorbency. It indicates the amount of water that can be absorbed in a certain period of time. The larger the water absorption rate, the better the water absorption performance of the product. The standard requires proof period underwears to be ≥9.0 times and sanitary pads to be ≥3.5 times.

   ph value ph value indicates the acidity and alkalinity of the product. Proof period underwears and sanitary pads are in direct contact with the human body. The acidity and alkalinity are neutral and have the least irritation to human skin. The standard requirements for superior products, first-class products and qualified products are 5.5 to 8.0, 5.3 to 8.2, and 5.3 to 5.3. 8.2.

   Adhesive strength standards only make qualitative requirements. Adhesive strength of the back adhesive refers to the condition that the adhesive of proof period underwears is firmly pasted. If the adhesive strength of the back adhesive is too large or too small, it is not conducive to use. It is easy to tear off when peeling off.

   Delivery moisture Delivery moisture refers to the moisture contained in proof period underwear products. Too much moisture will cause mildew on the raw materials and breed bacteria. The standard requirement is ≤10%.

   Consumers can compare the above index parameters one by one to check whether the product is truly "qualified".

  How to "see" the pros and cons of proof period underwears

   The outer packaging of proof period underwears should have the following marks: sanitary license number, production date, shelf life or validity period, implemented standard number (gb8939-1999, gb15979-2002), manufacturer's name and address, etc.

   Consumers should choose proof period underwears with full marks and try their best to choose proof period underwears newly produced.

  The sealing of each outer package and individual small package should be smooth and free of air leakage; a good proof period underwear should have a clean surface, uniform thickness, and no damage to the sealing.

   In addition, from the perspective of hand feel, a good proof period underwear is made of fluff pulp with strong absorption and good fluffiness, so it is light and soft. If the proof period underwears are mixed with other pulp, leftovers, etc., they will be heavy and hard.
