Hot air-turough nonwoven fabric: A soft upgrade for the bottom layer of diapers

Hot air-turough nonwoven fabric uses polymer fibers as raw materials. After being air-laid, hot air is used to penetrate the fiber layer to achieve bonding, without the need for additional adhesives. This process allows the fibers to form a random and uniform distribution in three-dimensional space, creating a fluffy structure. This softness is not a one-dimensional tactile experience, but comes from the loose connection between the fibers. When exposed to external forces, the fibers can produce a certain deformation buffer, thereby reducing the friction on the skin. The integrity of its structure ensures that it is not easy to fall or break during use, taking into account the dual characteristics of softness and durability. ​

Special requirements for the softness of the bottom layer of diapers
Diapers are sanitary products that are in long-term contact with infants and special groups. The touch of the bottom layer material directly affects the use experience and product evaluation. As the first part of the product that consumers come into contact with, the texture of the bottom layer will form a preliminary judgment of the product quality. Infants and young children have delicate skin, a thin stratum corneum, and are more sensitive to external stimuli. Too hard bottom layer materials are easy to rub against the skin during activities, which may cause discomfort or even skin problems. For adult users, the soft bottom layer can improve the comfort of wearing and reduce the foreign body sensation during activities. Diapers need to fit the body curve during use. The soft bottom layer material can better adapt to the body's activities, maintain a good fit, and avoid the risk of side leakage caused by the stiffness of the material.

Hot air-turough nonwoven fabric meets the performance requirements of the bottom layer of diapers
The application of hot air-turough nonwoven fabric in the bottom layer of diapers does not rely solely on a single soft property, but on the precise matching of its comprehensive performance with the functional requirements of the bottom layer. From a structural point of view, its fluffy fiber network can effectively block the back-infiltration after liquid penetration, and at the same time use its own breathability to discharge the hot and humid air, reducing the dampness of the bottom layer in contact with the skin. In terms of softness, as mentioned above, the tactile advantage brought by its unique fiber structure can directly improve the comfort of the product and meet consumers' core demand for "soft and skin-friendly" diapers. Hot air-turough nonwoven fabric has a certain tensile strength and elasticity. It can stretch moderately with the body's movements during the wearing of diapers to avoid affecting the freedom of movement due to material restrictions. The uniformity of fiber distribution during its production process ensures consistent thickness of the bottom layer, avoids local hardness or thinness, and ensures the stability of the overall performance.

The application of hot air-turough nonwoven fabric improves the comprehensive competitiveness of diapers
The improvement of product competitiveness often comes from the precise response to user needs. The application of hot air-turough nonwoven fabric in the bottom layer of diapers is the embodiment of this logic. When consumers buy diapers, in addition to paying attention to absorption performance, they are increasingly sensitive to touch. Products that use hot air-turough nonwoven fabric as the bottom layer can convey a "high quality" signal through the soft experience at the first contact, thus forming a differentiated advantage among similar products. This differentiation is not achieved through complex functions, but by optimizing the user experience from the basic material level, which is easier to gain consumer recognition and trust. Hot air-turough nonwoven fabric has strong processing adaptability. It can adjust parameters such as thickness and gram weight according to product design requirements to meet the production requirements of diapers of different grades, providing companies with flexible material choices in product upgrades or market segmentation layout. The environmental friendliness of its production process is also in line with current consumers' preference for green products, indirectly enhancing the market acceptance of the product.
