Polyester fiber and polypropylene fiber: performance difference and applicability analysis of piece type printed spunlace nonwovens

In the vast field of modern materials science, nonwovens, as an important nonwoven material, have become an indispensable part of industrial production and daily life with their unique structure and wide application fields. Among them, piece type printed spunlace nonwovens have attracted widespread attention in the market with their exquisite appearance, good air permeability and diverse functionality. In the process of manufacturing such nonwovens, the choice of fiber type plays a vital role. This article will focus on the application of polyester fiber and polypropylene fiber in piece type printed spunlace nonwovens, as well as the performance differences and applicability they bring.

Polyester fiber: synonymous with strength and stability
Polyester fiber, with its excellent physical properties and chemical stability, occupies a pivotal position in the production of piece type printed spunlace nonwovens. Nonwovens made of polyester fibers not only have high strength and elastic modulus, but also can maintain morphological stability during long-term use. This characteristic makes polyester fiber nonwovens perform well in environments with certain pressure and friction, such as medical supplies, electronic product packaging, and automotive interiors. In these applications, non-woven fabrics not only need to have good physical properties, but also need to maintain their original form and function in complex and changeable use environments. Polyester fiber is undoubtedly the best choice.

In addition, polyester fiber also has excellent weather resistance and anti-aging properties, which means that even if used outdoors or in harsh environments, it can maintain its stable performance for a long time. This is especially important for products that need to be exposed to natural factors such as sunlight, wind and rain for a long time.

Polypropylene fiber: the perfect combination of elasticity and wear resistance
Compared with polyester fiber, the application of polypropylene fiber in sheet-printed spunlace non-woven fabrics is more reflected in its elasticity and wear resistance. With its unique molecular structure, polypropylene fiber gives non-woven fabrics good elasticity and recovery, allowing the product to quickly return to its original state after being subjected to external forces. This feature makes polypropylene fiber non-woven fabrics widely used in clothing accessories, furniture packaging, and disposable sanitary products. In these applications, non-woven fabrics need to have a certain degree of elasticity and softness to meet the comfort and functional requirements of the product.

At the same time, polypropylene fiber also has good chemical stability and wear resistance, and can maintain its stable performance in a variety of chemical environments. However, compared with polyester fibers, polypropylene fibers may be more prone to aging and breaking during long-term use. This limits its application in certain high-strength applications, such as environments that require heavy pressure or frequent friction.

Polyester fibers and polypropylene fibers have their own advantages in the application of piece type printed spunlace nonwovens. Polyester fibers are ideal for manufacturing products that need to withstand pressure and friction due to their high strength and stability; while polypropylene fibers shine in areas such as clothing accessories and disposable sanitary products due to their elasticity and wear resistance. When choosing fiber types, we need to make comprehensive considerations based on the specific needs of the product and the use environment to ensure that the performance and applicability of the nonwoven fabric are optimal. With the continuous advancement of materials science and the continuous innovation of technology, I believe that more nonwoven materials with excellent performance and diverse functions will be available in the future, bringing more convenience and beauty to our lives.
