Sizing Home Cleaning Non-Woven Fabric: Key Process to Improve Performance

In the field of modern household cleaning products, non-woven materials are widely used in rags, wipes, wet wipes and other products due to their lightness, softness, good water absorption and non-linting properties. In order to further improve its strength, wear resistance and adsorption performance, Sizing Home Cleaning Non-Woven Fabric has become an important choice in the production of household cleaning non-woven fabrics.

What is Sizing Home Cleaning Non-Woven Fabric?

"Sizing" was originally a treatment method in the textile industry to enhance yarn strength and reduce the breakage rate. It has also been introduced in the non-woven fabric industry as an important way to improve surface performance. The so-called "sizing of household cleaning non-woven fabrics" refers to the process of applying a certain type of sizing (such as PVA, CMC, acrylic acid, etc.) to the surface of the material during the production or finishing of non-woven fabrics to give it a better performance.

Common household cleaning non-woven fabrics are mostly made by spunbond, hot air, spunlace, etc. Although spunlace nonwovens have certain strength and water absorption, in actual use, users often need them to have stronger friction resistance, better dry and wet strength, and better oil absorption capacity. At this time, sizing treatment can effectively enhance these key properties.

Analysis of the main purpose and advantages of sizing

1. Improve wet strength and wear resistance

Ordinary nonwovens are prone to loose structure and damage in a wet state. Sizing can form a protective film on the fiber surface, effectively preventing structural degradation in a wet environment and extending the service life of the product.

2. Enhance adsorption and cleaning ability

For difficult-to-clean substances such as kitchen oil stains and bathroom scale, use nonwovens that have been sizing. The surface can more easily adhere to fine particles and grease, improve cleaning efficiency, and is not easy to leave residue.

3. Improve the feel and softness

Different types of sizing can adjust the touch of nonwovens, making the product closer to the skin and more elastic, and improving the user experience.

4. Enhance antibacterial and mildew-proof function (optional)

Adding antibacterial agents or silver ions to the slurry can give the product a certain antibacterial ability, which is especially suitable for humid environments such as kitchens and bathrooms to avoid mildew and odor.

Common process flow of household non-woven fabric sizing
The sizing treatment of household cleaning non-woven fabrics can usually be completed at the end of the production line or on the finishing line. The typical sizing process is as follows:

1. Slurry configuration
Prepare suitable slurry according to the purpose of the product. Common compositions are: polyvinyl alcohol (PVA), sodium carboxymethyl cellulose (CMC), acrylic emulsion, nano-silica sol, surfactant, etc.

2. Sizing method
Sizing is carried out by padding, spraying or coating. Among them, padding is the most widely used, which can ensure that the slurry fully penetrates the fiber gap, and the coating method is suitable for focusing on enhancing the single-sided performance.

3. Drying and curing
The sizing non-woven fabric needs to evaporate the water by hot air or infrared drying, and the slurry is evenly cured on the surface.

4. Rewinding and testing
The dried product needs to be tension-controlled, flattened, and automatically wound, and the appearance and performance tests are carried out at the same time to ensure that the product meets the specifications.

By reasonably selecting the type and concentration ratio of slurry, the product functions can be customized to meet the diverse cleaning needs of the family.

With the consumption upgrade of household cleaning products and the change of lifestyle, household cleaning non-woven fabrics are no longer "cheap consumables" but "high-performance home assistants". Sizing treatment, as a key link to improve the performance of non-woven fabrics, is becoming the core of differentiated competition for corporate products.
