Thermal bonded nonwoven plays an important role in the manufacture of personal hygiene products.  In the manufacture of diapers, it is not only often used as a material for wrapping the core to ensure the stability of the polymer absorbent material, but also as a diaper topsheet material. With its light, thin and soft characteristics, it greatly reduces the friction on the baby's skin. At the same time, its excellent breathability helps prevent diaper rash, and its high strength improves the overall durability of the diaper.  In the field of sanitary napkins, thermal bonded nonwoven also performs well. It can be used as a sanitary napkin topsheet material (sanitary napkin surface material) to provide a soft and skin-friendly touch, effectively prevent side leakage, and because of its excellent moisture absorption and breathability properties, it can quickly Drain menstrual blood and keep skin dry and comfortable.    In addition, the thermal bonded nonwoven fabric that has undergone special antibacterial treatment further reduces the risk of infection during use, and its light, thin and soft characteristics make the sanitary napkin lighter and more close-fitting.  In summary, the application of thermal bonded non-woven fabrics not only significantly improves the safety and comfort of diapers and sanitary napkins, but also effectively enhances the durability and overall performance of the products, becoming an indispensable key material in the manufacture of personal hygiene products.

Thermal bond hydrophilic nonwoven is widely used in diapers, mainly due to its many advantages. First, the physical properties of thermal bonding nonwoven fabric are highly matched with the needs of diapers. The high strength and durability of thermal bonding nonwoven fabric can withstand the weight of urine and the pressure caused by baby's activities. At the same time, its breathability helps to reduce the dampness inside the diaper and improve the baby's comfort. Second, the hydrophilic property makes diaper thermal bond nonwoven excellent in urine management. Through hydrophilic modification, the nonwoven fabric that may be hydrophobic can quickly absorb and disperse urine, reducing the residence time of urine on the surface of the diaper, thereby keeping the baby's skin dry and comfortable, and reducing the risk of skin problems such as diaper rash. In practical applications, diaper thermal bond nonwoven is usually used in conjunction with an absorbent core to ensure effective urine management. At the same time, in order to improve the user experience of diapers, it is necessary to take into account multiple aspects such as breathability, moisture absorption, softness and comfort, which can be achieved by optimizing the production process and material formula. These advantages make thermal bond hydrophilic nonwoven an ideal choice in diaper manufacturing.

As a modern cleaning product, the quality of wet wipes is closely related to the selected wet wipes raw materials. Among them, spunlace nonwoven fabric uses high-pressure water flow to entangle the fibers, combining the softness of textile fabrics with the toughness and water absorption of nonwoven fabrics, making it an ideal material for manufacturing spunlace wipes. Spunlace nonwoven wipes are soft and comfortable, suitable for direct contact with the skin, and their fiber structure ensures rapid water absorption and keeps them moist for effective cleaning. At the same time, the toughness and durability make the wet wipes not easy to break, improve the user experience, and extend the service life. Environmental protection is another highlight of spunlace nonwoven fabrics. No chemicals need to be added during the production process, which is in line with the concept of environmental protection, and the production cost is low, which helps to reduce the price of wet wipes. Spunlace nonwoven wipes are widely used, suitable for household cleaning, personal hygiene, baby care and outdoor travel, etc. They provide a soft and durable wiping surface, effectively clean stains, and have good air permeability to extend the shelf life of the product. However, it is necessary to change it in time to avoid bacterial growth. People with sensitive skin should choose products with reliable quality and safe ingredients.   In summary, the application of spunlace non-woven fabrics in wet wipes has multiple advantages. It not only improves the quality of wet wipes, but also conforms to the concept of environmental protection and reduces costs. In the future, spunlace non-woven wet wipes will play a more important role in daily life, bringing people a convenient, comfortable and environmentally friendly cleaning experience.

In the application of wet wipes, parallel spunlace nonwoven and embossed spunlace nonwoven in spunlace wipes have their own characteristics. Parallel spunlace nonwoven is thin and breathable, with good water absorption, but its water retention ability is relatively weak, and it needs to be frequently replenished. Its delicate and smooth surface feels soft and is suitable for direct contact with the skin, reducing friction and irritation, and improving comfort. In contrast, embossed spunlace nonwoven uses pearl embossing technology, which has better water absorption and water retention. It can quickly absorb water and stains while maintaining moisture, reducing water loss, and providing a lasting cleaning effect. Although it is slightly inferior to parallel spunlace nonwoven in softness, the pearl texture has a certain thickness and elasticity, which improves the wiping fit and wrapping feeling, and cleans more comprehensively. In terms of durability and applicable scenarios, parallel spunlace nonwoven is soft and breathable, but has weaker durability, and is suitable for soft products such as facial wipes. On the other hand, embossed spunlace nonwoven has high strength and durability, can withstand more wipes and heavier stains, and is more suitable for high-intensity cleaning scenarios such as kitchens and bathrooms. In summary, parallel spunlace nonwoven and embossed spunlace nonwoven have their own advantages in wet wipe applications.

Wet Strength Paper plays a vital role in diapers. As a key component of the absorbent core, carrier tissue, it significantly improves the performance of diapers. Wet Strength Paper is a paper that has been specially processed to maintain high strength in a wet state and is not easy to break or deform. This feature makes it an ideal choice for absorbent products such as diapers. In diapers, carrier tissue plays three main functions: first, it guides urine to quickly penetrate into the core layer, ensures that urine is evenly distributed, reduces surface retention time, reduces re-seepage, and keeps dry; second, it enhances the structural stability of the absorbent core layer to prevent the material from swelling, deforming or rupturing due to water absorption; third, it improves the durability of diapers, so that they remain intact even after multiple uses, extending their service life. Wet Strength Paper is often used in conjunction with absorbent materials such as SAP (super absorbent polymer) and fluff pulp as a supporting structure to ensure that these materials fully exert their performance and jointly build an efficient and stable absorption system. This combination not only improves the absorption speed of diapers and reduces urine retention time, but also significantly enhances dryness, reduces the contact time between baby's skin and urine, and reduces the risk of skin problems such as diaper rash. At the same time, the strength and stability of Carrier Tissue ensure the shape and fit of diapers after multiple uses, improving the wearing comfort of babies. In summary, the application of Carrier Tissue in diapers is crucial. It not only improves the absorption speed, dryness and comfort of diapers, but also enhances structural stability and durability. Therefore, when choosing diapers, consumers should pay attention to whether they contain high-quality materials such as wet-strength paper to obtain a better use experience.

The key to wet strength tissue being resistant to water is its unique manufacturing process and composition. During the production process, wet strength paper is added with a wet strength agent, a chemical additive that can form chemical bonds or physical crosslinks with paper fibers, thereby significantly enhancing the strength of the paper in a wet state. Common wet strength agents include polyamide polyamine epichlorohydrin (PAE) resins, etc., which can prevent the bonding between fibers from being completely destroyed by water, allowing the paper to maintain a certain structural integrity. In addition, the fiber structure of carrier tissue paper has also been optimized, so that the carrier tissue paper part can maintain high strength and toughness after being wet, further improving the durability of the paper. At the same time, multiple processes in the production process, such as calendering and drying, also help to improve the density and smoothness of the paper, making it less likely to break in a wet state. Wet strength paper (including wet strength paper as tissue paper) is widely used in absorbent products such as diapers and sanitary napkins due to its resistant property to water, as well as special-purpose paper (tissue paper) such as map paper and banknote paper that need to withstand a humid environment. These application scenarios have high requirements on the wet strength of paper, and wet-strength paper is the ideal choice to meet these needs.

Fluff pulp plays a vital role in diapers. As one of the core absorbent materials, the characteristics of diaper fluff pulp directly determine the performance of diapers. Its fibers can quickly absorb and disperse urine with excellent moisture absorption, and work together with polymer absorbent resin (SAP) to form a powerful absorption system, ensuring that diapers remain dry for a long time and effectively reducing the baby's discomfort. In addition, the mesh structure of fluff pulp brings good breathability to diapers, helps reduce moisture accumulation, thereby preventing red buttocks and diaper rash, and carefully protecting the baby's delicate skin. At the same time, the softness of fluff pulp makes diapers fit the baby's body better, reduces friction, and further improves the comfort of wearing. In terms of structural stability, fluff pulp is closely combined with other materials such as SAP and non-woven fabrics to form a stable absorption layer. This structure not only effectively prevents the diaper from deforming or bunching up after absorbing water, but also maintains the integrity and high absorption efficiency of the diaper.

Treated fluff pulp (treated wood pulp) and untreated fluff pulp (untreated wood pulp) are significantly different in many dimensions. Fluff pulp, whether it is virgin wood pulp or recycled wood pulp (such as regenerated pulp), has been chemically or mechanically treated, a step designed to remove impurities and improve the purity and separation of fibers. In contrast, untreated fluff pulp is extracted directly from wood without any further treatment, so it contains more impurities and incompletely separated fibers. In terms of performance, fluff pulp shows higher absorption performance, its fiber structure is uniform, its air permeability is good, and it is soft and delicate, all of which help to improve the comfort of the product. At the same time, fluff pulp is more closely integrated with other materials, and its structural stability is strong, which can effectively prevent diapers from deforming or lumping after absorbing water. In contrast, untreated fluff pulp has poor absorption performance, air permeability and softness, and its structural stability is also insufficient. In terms of application and market demand, fluff pulp is widely used in high-end diapers, sanitary products and other fields due to its excellent performance, meeting consumers' demand for product quality and comfort. Untreated fluff pulp is mostly used in low-end or low-cost products, but as consumers' requirements for product quality and environmental protection continue to increase, its market demand may gradually decrease.

Diapers mainly have the following SAP sheet raw materials types: 1.Fleece pulp core: A traditional core made by mixing fluff pulp and polymer absorbent resin. It has good drainage properties, can quickly absorb urine and lock it in through polymer materials, keeping the baby's skin dry. However, the fluff pulp core is prone to clumping and fracturing due to its loose structure and lack of adhesive fixation. 2.Composite core: composed of dust-free paper, non-woven fabric, and polymer absorbent resin, bonded between each layer of material with hot melt adhesive. This type of absorbent core baby diaper is not prone to clumping or breaking, and can maintain its original shape after absorbing water, making it lightweight and comfortable. Although the process is complex and costly, it has stronger absorption and locking power, providing better comfort and absorption efficiency. 3.Full core body: mainly composed of high polymer water absorbing resin, with fast absorption speed, less reverse osmosis, good breathability, but relatively hard. 4.Ultra thin absorbent core: Similar to a full core, but thinner and more lightweight.

Sanitary napkins, as an indispensable item in women's daily life, the choice of sanitary napkins topsheet material is directly related to the comfort and health of use. So, what are the topsheet materials of sanitary napkins? What are their respective characteristics? The most common sanitary napkins topsheet material is nonwoven. Nonwoven fabrics are soft, breathable, and absorbent. They can quickly absorb and disperse menstrual blood, keep the surface dry, and reduce moisture and discomfort. In addition, nonwoven fabrics also have good wear resistance and tear resistance, are not easy to break, and ensure the service life of sanitary napkins. The topsheet of dry mesh sanitary napkins is carefully made of various perforated films treated with special processes as raw materials. These perforated films are covered with fine micropores, so that liquids such as menstrual blood can quickly penetrate through these micropores into the lower absorbent layer and be effectively absorbed. This design not only ensures the dryness of the surface of the sanitary napkin, but also improves the breathability, reduces moisture and discomfort, and provides women with a more comfortable use experience. In recent years, sanitary napkins with a soft cotton topsheet have also appeared on the market. The soft cotton surface is made of natural cotton fiber, which is softer and more comfortable to the touch and less irritating to the skin. At the same time, the soft cotton surface also has good moisture absorption and breathability, which can keep the private parts dry and clean. However, it should be noted that the price of sanitary napkins with a soft cotton surface is relatively high, and in certain special environments (such as high temperature and humidity), it may be more likely to breed bacteria, so more attention should be paid to keeping them clean and dry when using them.

The diaper absorbent core of baby diapers is the core component that realizes its urine absorption function, which mainly relies on the excellent performance of polymer absorbent resin (SAP). SAP can absorb and lock a large amount of water, and its water absorption capacity is so strong that it can reach hundreds or even thousands of times its own weight. In the structure of diapers, absorbent polymer exists in granular form and is mixed with fluff pulp to form the absorbent layer. When urine touches the surface layer of the diaper (usually made of non-woven fabric), the urine will be quickly received and transferred to the diversion layer, which is also made of non-woven fabric to ensure that the urine can be evenly distributed to the absorbent layer. In the absorbent layer, the hydrophilic group of SAP immediately takes effect, quickly attracting and fixing water molecules, causing the SAP particles to swell and fuse with each other, thereby efficiently absorbing urine. SAP itself has the property of being insoluble in water, so it can absorb a large amount of urine without exudation. At the same time, its excellent water retention capacity ensures that the urine is firmly locked inside the diaper, effectively preventing urine backflow or leakage. In summary, the process of urine absorption by polymers in baby diapers is a complex system involving multiple efficient steps such as urine reception, conduction, absorption and locking. This process ensures that diapers can quickly and effectively absorb and lock urine, providing babies with a lasting dry and comfortable experience.

Super absorbent polymer , as the core of sanitary napkin absorbent materials, is undoubtedly a perfect combination of technology and comfort when used in sanitary napkins. SAP has demonstrated the following outstanding effects: Extraordinary water absorption performance: SAP has excellent water absorption capacity, which can quickly absorb and firmly lock a large amount of liquid, such as menstrual blood, to ensure that the sanitary napkin remains dry in the face of turbulent liquid flow, effectively relieving moisture and discomfort.   Stable water retention performance: After absorbing water, SAP will form a stable gel structure, which is difficult to release water molecules even under external pressure. This excellent water retention performance prevents the sanitary napkin from quickly re-seeping after absorbing liquid, thus keeping it dry for a long time. Significant anti-side leakage effect: SAP's water absorption and expansion characteristics form a solid barrier inside the sanitary napkin, effectively preventing the liquid from spreading to both sides, significantly reducing the risk of side leakage.   Improved comfort: SAP is soft and skin-friendly, making the sanitary napkin fit the skin better during use, significantly reducing friction and discomfort, and improving the overall user experience. In summary, super absorbent polymer (SAP), as a key absorbent material in sanitary napkins, plays multiple important roles such as water absorption, water retention, leakage prevention and comfort improvement, bringing women a more comfortable and dry experience during menstruation.
