Description

Technical Field

[0001] The present invention relates to the technical field of non-woven fabric detection, and in particular to a tensile strength detection device and method for non-woven fabric production. Background Art

[0002] With the increasingly diversified user needs, many new types of non-woven fabric products have emerged, such as hot air probiotic water-sprayed non-woven fabrics, perforated non-woven fabrics, 3D non-woven fabrics, 3D perforated non-woven fabrics, hot air diversion layer non-woven fabrics, hot air color antibacterial non-woven fabrics and 3D composite partitioned non-woven fabrics. Non-woven fabrics are widely used in medical, industrial and daily necessities. Daily necessities include children's diapers, panty liners, sanitary napkins, etc. When new material non-woven fabrics are produced, their various properties need to be strictly tested. Tensile performance is one of the core parameters for measuring product quality. Tensile performance includes indicators such as tensile strength and elongation at break. Poor tensile resistance of non-woven fabrics will affect the reliability of the product.
