spunbond nonwoven polypropylene fabric

Nonwoven spunbond fabric is widely used in pull-up pants, mainly because of its excellent physical properties and processing characteristics. Pull-up pants are a kind of baby diapers or adult incontinence pants, usually including multiple layers of materials, and the role of nonwoven spunbond fabric in them is mainly reflected in the following aspects: 1. Surface layer (outer layer) Spunbond nonwoven fabric is often used as the outer layer material of pull-up pants. Its main functions are: Softness and comfort: Spunbond nonwoven fabric has good softness, can provide a comfortable touch to the skin, and reduce friction when wearing. Breathability: Spunbond nonwoven fabric has good breathability, which helps to keep dry, reduce moisture accumulation, and avoid problems such as stuffiness or eczema on the skin. Durability: Spunbond nonwoven polypropylene fabric has high strength and can provide sufficient support to prevent pull-up pants from breaking or losing shape during use. 2. Inner layer (water-absorbing layer) Although spunbond nonwoven fabric itself is not absorbent, its application in the inner water-absorbing layer of pull-up pants cannot be ignored. It mainly plays the following roles: Distribute liquid: spunbond nonwoven fabric is usually used as the distribution layer of the water-absorbing layer to help urine be evenly distributed to the water-absorbing material (such as polymer absorbent) on the lower layer, making the water-absorbing process more efficient. Enhance structural stability: By providing a certain strength and support, the water-absorbing layer is more stable, which helps to maintain the overall shape of the pants. 3. Sides and edges Spunbond pp nonwoven material is also commonly used in the side or edge parts of pull-up pants: Sealing and leakproof: It helps to increase the sealing of the pants and prevent urine from leaking from the edges. Especially in the waist and leg design of pull-up pants, spunbond nonwoven fabric can effectively cooperate with elastic materials to increase wearing comfort and leakproof effect. 4. Composite layer During the manufacturing process of pull-up pants, spunbond nonwoven polypropylene fabric may also be used in combination with other materials (such as meltblown nonwoven fabrics, breathable films, etc.): Enhanced comprehensive functions: By combining with other materials, spunbond nonwoven fabrics can play a better comprehensive performance, such as improving breathability and waterproofness, making pull-up pants more suitable for infants or adults. 5. Cost control The production cost of spunbond nonwoven fabrics is relatively low, which can effectively reduce the overall production cost. Therefore, it can balance performance and price in the application of pull-up pants and meet the market's requirements for cost-effectiveness. Summary: Spunbond nonwoven fabrics play a very important role in pull-up pants because of their softness, breathability, high strength, and strong adjustability. It not only provides comfort and breathability, but also helps improve the leakage resistance and structural stability of pull-up pants, and also has certain advantages in manufacturing costs. Therefore, the application of spunbond nonwoven fabrics in pull-up pants is a key factor in its becoming one of the mainstream materials in the market.
