What is "Cold Sensitive Non-woven"？
"Cold-sensitive non-woven fabric", also called PE matte fabric, was first invented in Japan. However, the habit of wearing face masks is very common in Japan and people often wore masks when they went out even before the Covid. During the hot summer months, people need to wear masks at all times. But wearing the stuffy and non-breathable traditional masks is also a great headache for the public. Cold-sensitive masks came into being.
The emergence of cold-sensitive non-woven fabric allows the general public not to worry about stuffiness and lack of breathability in the hot summer months. This is why it has gained popularity in Japan as soon as it was launched.
The cold-sensitive mask is made by replacing the skin-contacting lining of traditional masks with a cold-sensitive nonwoven fabric. So it will feel very cool after wearing. The coolness felt by human skin is also graded. The higher the Qmax coolness value, the higher the coolness felt. Generally, products made of cold-sensitive non-woven fabric will have Qmax cold-sensitive value marked on the outer box of the mask. The higher the Qmax cold-sensitive value is marked, the cooler the feeling will be after using or wearing.
The manufacturing process of cold-sensitive non-woven fabric is to take the processed PE matte fabric and then submerge it in water, the soaking process will adsorb the cold-sensitive factor which is harmless to human body on the nonwoven fabric, and then dry it to become cold-sensitive nonwoven fabric. Its technological content and manufacturing difficulty is not high, but for the process requirements and cold-sensitive impregnation of the liquid formula, it requires numerous trials to achieve the best cold-sensitive state. Cold-sensitive non-woven is in fact a functional product with deeper application of non-woven fabric, and its development is based on a broad market demand and application scenarios.
This also led to the Covid in China after many manufacturers also began to produce this cold-sensitive non-woven, but the quality and the actual cold-sensitive effect is very different.
For quality cold-sensitive non-woven fabric should have the following characteristics.
Colorless, odorless, cool, smooth, Qmax cold-sensitive value marked with positive and negative deviation of not more than 0.2. The current cold-sensitive non-woven on the market mainly has Qmax cold-sensitive value of 0.2, 0.25, 0.3, 0.35, 0.4, 0.45 these standards, the price is also linked to the cold-sensitive value.
For factories who need to purchase cold-sensitive non-woven fabrics, you can look for some medium and large factories that have certain experience in scale and R&D to cooperate, and send samples to third-party testing institutions for testing before purchasing, and keep samples for inspection.
