2. Compression recovery performance
Referring to the general post-service production management standard JSB9.3-92 [ determination of the unit area mass, the compression elastic rate and the fluffiness of the flocculus ], the area of a sample is 10cm multiplied by 10cm, and the light pressure condition is: placing 100g of pressing plate on the sample, wherein the pressing pressure is 0.1kpa; the weight conditions were: a weight having a mass of 1250g was placed on the platen. The testing steps are as follows: firstly, the apparent thickness h1 (mm) is measured after light pressing for 1 minute, secondly, the stable thickness h2 (mm) is measured after heavy pressing for 5 minutes, finally, the flat plate and the heavy hammer are taken down, the sample is restored for 1 minute under no load, the pressure plate is used for pressing for 1 minute, the restored thickness h3 (mm) is measured, and the calculation formula of the data related to the compression performance is as follows
The following is shown: the compression elasticity R (%) = (h 3-h 2)/(h 1-h 2) ×100%

The measurement was repeated at least lO times at different positions on the same sample, and an average value was calculated.
4. Tensile Properties
Reference standard GB/T3923.1-1997 section 1 of tensile Property of textile fabrics: measurement of breaking Strength and elongation at break (measurement of breaking elongation) 5 samples with a size of 200mm×50mm were taken in the longitudinal (warp) and transverse (weft) directions of the nonwoven fabric, and the data were tested and recorded using a YG 065H-type electronic fabric tester with a gauge of 200mm and a tensile speed of 100mm/min, and averaged.
