The early wet wipe materials mainly used hot-rolled non-woven fabrics or pulp air-laid non-woven fabrics (dry-laid paper), which have been rapidly replaced by spunlace non-woven fabrics in recent years. Spunlace non-woven fabrics are soft to the touch, have good hygroscopicity, and have a high liquid holding rate, making them ideal raw materials for wet wipes. This article briefly describes the performance and quality requirements of Spunlace non woven fabric for wet wipes.

1. Properties of spunlace nonwovens

The spunlace non-woven fabric has a certain strength and thickness, which can meet the water absorption performance requirements of wet wipes. Spunlace nonwovens are non-toxic and non-irritating, and the pH value is basically guaranteed to be weakly acidic. The pH value of human skin is acidic. In order to protect the baby's skin, the pH value of baby wipes is usually around 4.5~5.5.

2. Raw materials of spunlace non-woven fabrics

There is no chemical reaction process or addition of chemical components in the production process of spunlace nonwovens, only the high-pressure water that has been filtered through multiple channels is used to physically strengthen the fibers. Fiber quality has an important impact on the quality of spunlace nonwovens, and high-quality spunlace nonwovens must require high-quality fiber raw materials. The raw materials of spunlace nonwovens are mostly viscose fibers and polyester fibers. High-quality wet wipes spunlace non-woven fabrics mostly use polyester fibers and high-whiteness viscose fibers for non-woven fabrics, which have cleanliness, spinnability, whiteness and safety (such as odor, PH value, heavy metal content) of the fibers. etc.) performance requirements. For example, the viscose bleaching process requires the use of hydrogen peroxide instead of the usual chlorine bleach to avoid irritating chlorine ions. At the same time, there are strict requirements for the sulfur content of viscose fibers.

3. Microbial content of wet wipes

Microbial content is the most important quality indicator of wet wipes. As one of the most important raw materials of wet wipes, in order to ensure the safety factor of microbial control of wet wipes, it is necessary to monitor the microbial indicators of spunlace cloth. Generally, the total number of bacterial colonies of spunlace nonwovens is required to be less than 300cfu/mL. In the actual production process of spunlace nonwovens, after washing in the spunlace process and drying with hot air above 100°C in the drying process, the total number of bacterial colonies in the spunlace nonwovens is less than 50cfu/mL, generally 0~15cfu/mL between. The main sources of pollution that affect the microbial quality of spunlace nonwovens are air dust in the production environment, work surfaces, operator's palms and clothes, and items that come into contact with spunlace nonwovens. If we have good control of the above pollution sources, under suitable packaging and inventory environment, the total bacterial colony of spunlace nonwovens will still be less than 100cfu/mL even after one year. The spunlace nonwoven packaging material should be non-toxic, harmless, non-polluting, not easy to be damaged, and have certain moisture-proof and dust-proof functions to prevent secondary pollution.

In recent years, spunlace non-woven fabrics have become more and more commonly used in wet wipes. Understanding the performance and quality requirements of Spunlace non woven fabric for wet wipes will help people choose and use wet wipes better.
