Description

Technical Field

[0001] The utility model belongs to the technical field of automotive non-woven fabric detection, and particularly relates to a water absorption detection device for automotive non-woven fabric. Background Technique

[0002] Non-woven fabric is a non-woven fabric. It directly uses polymer chips, staple fibers or filaments to form a web of fibers through air flow or mechanical means, and then is reinforced by hydroentangling, needling, or hot rolling. Finally, it is formed into a non-woven fabric through post-treatment. It is a new type of fiber product with softness, breathability and a flat structure. There are many items in the quality control of non-woven fabric, and one of the very important items is the detection of water absorption, which is very important for the quality of the product.
