Professional procurement of non-woven fabrics needs to understand this knowledge
November 30, 2021
Spunbond non-woven fabrics are widely used in the manufacture of sanitary materials, agricultural materials, furniture materials, packaging materials, medical materials, industrial materials and other products due to their low price, good physical and mechanical properties and aerodynamic properties.
In addition to the well-known masks and non-woven bags, non-woven fabrics are used in our daily mattresses, sofas, automobiles, and various packaging. There are many downstream manufacturers using non-woven fabrics as raw materials.
So how do manufacturers judge the quality of non-woven fabrics when purchasing non-woven fabrics? When we get a sample of non-woven fabric, we can evaluate from these aspects:
The first thing is to look at the appearance, and pay attention to whether the model has the following problems:
Holes, poor trimming, color difference, lumps, foreign matter, uniformity
Then analyze the internal quality from the following aspects:
Width deviation, weight deviation per square meter, coefficient of variation of mass per unit area, breaking strength, elongation at break
According to different application , the following items can also be selectively tested:
Wear resistance, flame retardancy, PH value, oxidation resistance, UV resistance, hydrophilicity, water resistance, etc.
Of course, in addition to looking at the samples, it is better to go to the manufacturer for on-site inspection if conditions permit. In this way, you can intuitively understand the manufacturer's production scale, whether the operation is standardized, and the quality of service.
