Sized Non-woven Fabric: Process Innovation and Application Expansion

Non-woven fabric, an outstanding representative of modern environmentally friendly materials, is gradually becoming an indispensable part of all walks of life with its unique production process and wide application fields. In the production process of non-woven fabrics, the sizing process, as a key link to improve product performance, has injected new vitality into the application expansion of non-woven fabrics.

Sizing is to apply a layer of special slurry on the surface of non-woven fabrics to increase its thickness, stiffness, wear resistance and washability. This process not only enhances the strength of non-woven fabrics, but also improves its durability, allowing non-woven fabrics to maintain stable performance in more severe environments.

The selection of sizing materials is crucial. Commonly used sizing materials include natural starch, synthetic sizing, etc. These materials have good adhesion and film-forming properties, and can effectively adhere to the surface of non-woven fabrics to form a protective film. In the sizing process, a certain concentration of slurry needs to be prepared first, and then it is evenly applied to the surface of the non-woven fabric to ensure that every part is covered. Subsequently, the slurry is solidified into a film through drying treatment, and finally the sized non-woven fabric is inspected and trimmed to ensure the stability and consistency of the product.

Sized Non-woven Fabric not only retains the original characteristics of non-woven fabrics such as moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, but also further improves its performance through the sizing process. The sizing non-woven fabric is stiffer and feels better, and has better wear resistance and washability, making its application in multiple fields possible.

With the increasing awareness of environmental protection, degradable sized non-woven fabrics have gradually become the new favorite of the market. While maintaining the original performance, this type of non-woven fabric can also be quickly decomposed in the natural environment, reducing pollution to the environment, which is in line with global environmental protection trends and market demand.

Sized Non-woven Fabric has a wide range of applications, covering medical and health, household products, industrial materials, packaging materials and other fields.

In the field of medical and health, sized non-woven fabrics are widely used in the production of medical supplies such as surgical gowns, protective clothing, disinfection wraps, and masks. Its good air permeability and moisture resistance ensure the comfort of medical staff during long-term wearing; and its excellent wear resistance and washability extend the service life of medical supplies and reduce medical costs.

In the field of household products, sizing non-woven fabrics also show great application potential. Whether it is bedding, furniture decoration or cleaning products, sizing non-woven fabrics can meet the needs of consumers with their unique performance advantages. For example, sheets and bedspreads made of sizing non-woven fabrics are not only soft and comfortable, but also have good wear resistance and washability, making home life more convenient and beautiful.

In the field of industrial materials and packaging materials, sizing non-woven fabrics also play an important role. Its excellent physical properties and chemical stability make it widely used in roofing waterproofing membranes, asphalt shingle substrates, reinforcement materials, polishing materials, filter materials, etc. In the field of packaging materials, sizing non-woven fabrics have become an ideal choice to replace traditional plastic packaging materials with their environmentally friendly and degradable characteristics.

With the continuous advancement of technology and the continuous changes in market demand, the development prospects of sizing non-woven fabrics will be broader. The introduction of emerging technologies such as nanotechnology and biotechnology will further enhance the performance and application scope of sized nonwoven fabrics. For example, through the application of nanocomposites, sized nonwoven fabrics can have excellent properties such as high strength, high modulus, high toughness, flame retardancy, and antibacterial properties, thereby expanding their application in high-end fields such as aerospace, automobiles, and medical treatment.
