What is spunbond hydrophobic

Definition and production method of spunbond nonwoven fabric

Spunbond non-woven fabric refers to a non-woven fabric made by bonding loose or thin film textile fibers or fiber aggregates with chemical fibers under capillary action using adhesives. The production method is to first use mechanical or chemical methods to make fibers or fiber aggregates, then mix them with adhesives, and fix them together by heating, melting or natural curing to form non-woven fabric.

Waterproof performance of spunbond nonwoven fabric

The waterproof performance of spunbond nonwoven fabrics varies due to various factors such as fiber composition, fiber length, fiber density, type of adhesive, adhesive dosage, and processing technology. In spunbond nonwoven fabrics, surface treatment methods such as hot air forming, high-pressure water flow, chemical impregnation, and composite are generally used to improve their waterproof performance.

How to choose spunbond non-woven fabric with waterproof function

1. The selection needs to be based on specific application scenarios. For situations with high waterproof requirements, it is recommended to choose products that have been processed through composite methods to improve waterproof performance;

2. Pay attention to the reputation and product reports of product manufacturers, choose products with certain brand awareness and quality assurance, and try to choose well-known brands for products without clear reports;

3. Choose the appropriate weight according to actual needs, as different weights have different waterproof properties;

The difference between hydrophilic and water-resistant spunbond nonwoven fabrics?

When we use spunbond nonwoven fabric, we all know that there are various types. What is the difference between hydrophilic spunbond nonwoven fabric and water repellent spunbond nonwoven fabric?

1. As is well known, ordinary spunbond non-woven fabrics are water repellent. In practical applications, water repellent non-woven fabrics also need to add water repellent masterbatch for better results, and having good water repellent performance is one of their significant characteristics. With this significant feature, we can use it to make some furniture items or shopping bags.

2. Hydrophilic non-woven fabric is a type of fabric produced by adding hydrophilic agents to ordinary non-woven fabric during its production process, or by adding hydrophilic agents to fibers during fiber production. Compared with ordinary spunbond non-woven fabrics, it has more hydrophilic agent functions. Why do we need to add hydrophilic agents? Because fibers or non-woven fabrics are high molecular weight polymers with few or no hydrophilic groups, they cannot achieve the hydrophilic properties required for non-woven fabric applications, so hydrophilic agents are added.

 Beware of purchasing traps

1. Judging the quality of a product based on its appearance is not scientific, and attention should be paid to its main materials and production processes

2. Don’t be misled by the promotional slogans of low-priced products, as they generally overlook important production details, material quality, and other factors, thereby reducing costs;

3. Try to go to regular shopping places to choose branded products, and understand the performance and quality reports of the products to ensure the purchase of suitable products.

Conclusion

In short, the waterproof performance of spunbond non-woven fabric depends on various factors. When choosing, it is necessary to select according to specific application scenarios, cite reliable quality reports and brand information, and avoid misunderstandings in the selection process.
