What tests do nonwovens usually do?

Non-woven fabrics are also called non-woven, needle-punched cotton and needle-punched non-woven fabrics. , is made of polyester fiber and polyester fiber (abbreviated as PET) through needle punching process, which can be made into different thicknesses, handfeel, hardness and so on. Non-woven fabrics tested by Zhongke generally do these projects:

1, antibacterial, mildewproof and acaricidal properties: antibacterial, mildewproof, antiviral and acaricidal properties.

2. Color fastness test: color fastness to washing, rubbing (dry and wet), water, saliva, light, dry cleaning, perspiration, dry heat, hot pressing, ammonia, scrubbing and ammonia bleaching.

3. Physical property detection: tensile breaking strength/force, tearing strength/force, seam slip, seam strength, bursting strength/force, pilling resistance, abrasion resistance, fabric density, weight, thickness, width, weft skew, yarn count, moisture regain, single yarn strength/force, appearance after washing and dimensional stability.

4. Functional test: air permeability, moisture permeability, combustion performance, waterproof performance (hydrostatic pressure, water splashing, rain) and electrostatic test.

5. Chemical properties test: PH value, composition analysis, color fastness (water resistance, sweat resistance, friction resistance and saliva resistance), formaldehyde content, azo test and heavy metals.
