Traditional sanitary napkins are difficult to decompose in natural environments due to the presence of non degradable materials such as plastic, which can cause pollution to the environment. The emergence of biodegradable sanitary napkins has to some extent alleviated this problem. Degradable sanitary napkins are usually improved in terms of raw material selection and production processes: Surface layer: The surface layer of biodegradable sanitary napkins is often made of natural plant fibers, such as pure cotton, bamboo fibers, and other biodegradable nonwoven fabric materials. These materials have good skin affinity, keeping the skin dry and biodegradable in natural environments. Absorbent core: Some biodegradable sanitary napkins use biodegradable polymer absorbent resins or natural fibers such as wood pulp as the main raw material, and add some degradation promoting additives to the absorbent core. Natural fibers such as wood pulp can gradually decompose under the action of microorganisms, while biodegradable polymer water absorbing resins can also undergo degradation reactions in specific environments. Backsheet layer: Degradable plastics such as polylactic acid (PLA) and polybutylene terephthalate (PBAT) may be used as the backsheet fillm material. These materials can decompose into harmless substances such as carbon dioxide and water within a certain period of time under specific conditions such as composting.   Production process: During the production process, companies that produce biodegradable sanitary napkins usually use some special processing techniques to ensure that these biodegradable materials can be effectively combined together while ensuring that the performance of the sanitary napkins is not affected. For example, using hot pressing technology instead of traditional chemical glue bonding reduces the use of chemicals and is also beneficial for product degradation.  

Have you ever wondered how sanitary napkins can maintain their absorbency while keeping us dry and comfortable? The secret lies in a small design on sanitary napkins perforated film.   Perforated film sounds like a film with many small holes on the sanitary napkin. Yes, you understand it correctly! It is usually made of polyethylene (PE), a natural and environmentally friendly material. These micropores are designed to be both delicate and practical. They are like small "vents" that allow sanitary napkins to absorb menstrual blood while maintaining breathability and reducing moisture and odor. Imagine that if the sanitary napkin does not have a perforated film, it will be like an airtight "small bag". After the menstrual blood is absorbed, moisture and heat will be "stifled" inside, which will not only make us feel stuffy and uncomfortable, but also easily breed bacteria and affect health. With perforated film, these problems are solved. However, the porosity of perforated film is also a science. If the porosity is too large, the liquid may permeate back to the surface; if the porosity is too small, it will affect the breathability and absorption speed. Therefore, sanitary napkin manufacturers must carefully calculate and design to make sanitary napkins that are both comfortable and safe!   Next time you use a sanitary napkin, think about those tiny and magical perforated films that are silently protecting your dryness and comfort. Although they are inconspicuous, they are an indispensable part of sanitary napkins, making our lives better and more comfortable.    

Diapers are an important part of modern infant and adult care products. The application of hot melt adhesive plays a vital role in their design and manufacturing process.

Spunbond nonwoven fabric, hot air nonwoven fabric and thermal bond nonwoven fabric can all be used as the topsheet materials of diapers, and they each have different advantages and disadvantages. The following is a detailed analysis of these three materials:   1. Spunbond nonwoven fabric Advantages: Spunbond nonwoven fabric has high strength, good elongation at break and tear strength, which makes diapers less likely to break during use. Spunbond nonwoven fabric is relatively thin, which helps to reduce the overall weight of diapers and improve the comfort of wearing. Disadvantages: Compared with hot air nonwoven fabric, spunbond nonwoven fabric is slightly inferior in softness and breathability, which may cause a certain friction to the baby's delicate skin and affect breathability. 2. Hot air nonwoven fabric Advantages: Hot air nonwoven fabric has high fluffiness and elasticity, which makes the surface of diapers fit the baby's skin better and provide better comfort and wrapping. Hot air non-woven fabrics are soft to the touch and will not cause excessive friction on the baby's skin. At the same time, they have good warmth retention and are suitable for use in colder environments. Hot air non-woven fabrics have good air permeability and water permeability, which helps keep the inside of the diaper dry and reduce the risk of red bottom. Disadvantages: Low strength and easy deformation: The strength of hot air non-woven fabrics is relatively low and it is easy to deform during pulling, so more frequent changes may be required to maintain the integrity of the diaper.   3. Thermal bond non woven fabric   Advantages: The production process of thermal bond non woven fabric is relatively mature and the cost is low, so the price is relatively affordable. Disadvantages: Hard feel and average breathability: Compared with hot air non-woven fabrics, thermal bond non woven fabric may feel slightly harder and have average breathability, which may not be suitable for babies with high comfort requirements. (Note: Thermal bond non woven fabric is relatively rarely used on the topsheet of baby diapers, and are more commonly used in the medical and health fields. The reason for mentioning them here is to provide comprehensive information.)   Summary: When choosing the surface material of diapers, you need to consider factors such as the baby's skin condition, activity level, and seasonal changes. If the baby has delicate skin and requires high comfort, you can choose hot-air non-woven fabrics as the surface of diapers; if the baby has a large amount of activity and needs stronger mechanical support, you can choose spunbond non-woven fabrics as the surface of diapers. At the same time, you also need to pay attention to the frequency of diaper changes and cleaning care to keep the baby's skin healthy and comfortable.

Sanitary napkin topsheet materials can use a variety of raw materials, the following are some common ones: Dry mesh material: The surface of this sanitary pad is made of polyethylene (PE) film with small holes, also known as perforated film. It has the advantages of fast absorption and long-lasting dry surface. However, because it is a chemical fiber component, it may cause allergic reactions such as itching, redness and swelling for women with sensitive skin.   Cotton surface material: The cotton surface is not pure cotton, but is made of non-woven fabrics such as polypropylene (PP). This material is soft and can give people a touch similar to pure cotton, but it has poor breathability and may make private parts feel stuffy during use. In addition, bleaching may be required during the production process, so most cotton surface sanitary napkins contain additives, but the allergenicity is relatively low. Pure cotton surface material: The pure cotton surface is made of natural cotton fibers interwoven into a uniform, thin and soft non-woven fabric. This material is soft and comfortable, with minimal irritation to the skin, and is suitable for most women. Compared with chemical fiber materials, pure cotton sanitary napkins are more skin-friendly and can reduce allergies. However, pure cotton products tend to turn yellow over time, and are prone to breeding bacteria and mites at a certain temperature of the human body.   In addition to the above materials, some sanitary napkins use high-quality non-woven materials such as hot air non-woven fabrics as the surface layer. These materials are soft, breathable, and not easy to irritate the skin. In general, the choice of sanitary napkin making raw materials depends mainly on personal skin conditions, needs, and budget. For women with sensitive skin, it is recommended to choose sanitary napkins made of natural materials such as pure cotton, silk or bamboo fiber; and for women who pursue a dry experience, dry mesh sanitary napkins may be a good choice.  

ADL nonwoven fabric is a key technology in sanitary products such as diapers. It is located between the surface material of sanitary products and the absorbent core, mainly responsible for guiding and diffusion control, aiming to improve the absorption efficiency of the product and user comfort.     The characteristics of ADL diversion layer are mainly reflected in the following aspects: Firstly, the ADL diversion layer has excellent diversion performance. When urine comes into contact with the surface of the diaper, the ADL flow guiding layer can quickly respond and guide the urine to the absorbent core. During this process, urine is efficiently dispersed throughout the entire core area, thereby improving the utilization rate of the core and reducing the retention time of urine on the surface of the diaper. Secondly, the ADL diversion layer also has a certain liquid storage capacity. Before the urine is absorbed by the core matrix, it can temporarily store a certain amount of urine to avoid rapid penetration into the bottom layer, which can lead to the occurrence of reflux. This feature not only improves the leak proof performance of diapers, but also ensures that the absorbent core can fully exert its water absorbing effect, extending the use time of diapers.     In addition, the ADL flow guide layer also has good breathability and flexibility. It is made of non-woven fabric material with a microporous structure, allowing air and moisture to freely circulate inside the diaper, keeping the baby's skin dry and comfortable. At the same time, the softness of the ADL flow guiding layer ensures that the diaper will not cause excessive friction and irritation to the baby's skin during wearing. Finally, the design of the ADL diversion layer also takes into account environmental protection and sustainability. It is made of biodegradable materials that can be decomposed by the natural environment after use, reducing pollution to the environment. This characteristic is in line with modern people's pursuit of green and environmentally friendly living concepts.
