What are the three protections for textiles

2020-12-16

The three protections for textiles refer to waterproofing, oil resistance, and stain resistance. These three effects can be achieved by using the three protections finishing agent on textiles. The so-called three protections finishing agent is a finishing agent that can change the surface properties of textiles and achieve waterproofing, oil resistance, and stain resistance.

The principle of three prevention finishing effect refers to the lotus leaf water repellent principle, which reduces the surface energy of textiles to form water, oil, and dirt repellent effects. For example, water droplets on textile fabrics form a lotus leaf effect, which will not absorb quickly like ordinary fabrics.

Here's to clarify that this three prevention effect is not permanent, and after multiple washes, the three prevention effect will gradually lose.

Before using the three prevention finishing agent to organize the fabric, it is necessary to keep the fabric clean and free from any residual additives. Attention should be paid to the pH value of the fabric, otherwise it will affect the three prevention finishing effect and increase costs.

The three prevention tests for textiles mainly assess the ability of textiles to withstand water, dirt, or oil droplets and dirt under certain conditions. The standards for detecting water resistance include AATCC 22, GB/T 4745, and ISO 4920. The standards for detecting oil resistance include AATCC 118, GB/T 19977, and ISO 14419. The standards for testing stain resistance are GB/T 30159.1-2013, etc.
