As environmental awareness grows, dispersible nonwovens are being used more and more in hygiene products, wipes and other areas. However, due to their specific usage scenarios, it is crucial to ensure the quality and safety of dispersible nonwovens. In this article, we will discuss in detail the testing standards of dispersible nonwoven fabrics to help enterprises ensure product quality and meet market demands.
I.Definition and application of dispersible nonwoven fabrics
A dispersible nonwoven is a material that can be quickly decomposed in water and is usually used in the manufacture of disposable products such as wet wipes and sanitary napkins. More and more consumers and manufacturers are choosing to use dispersible nonwovens due to their environmental friendliness. However, this material must meet certain strength and decomposition performance requirements during use to ensure its reliability and safety in practical applications.
II.Key test criteria for dispersible nonwovens
To ensure the quality of dispersible nonwovens, manufacturers need to follow a series of stringent testing criteria. Below are some of the key test criteria:
2.1 Decomposition performance tests
One of the most important tests for dispersible nonwovens is decomposition. The test assesses the rate and degree of decomposition of the material in water, usually by simulating an actual use environment. Commonly used test methods include:
Toilet Flush Test: Simulates the flushing process of a toilet to assess the decomposition of the nonwoven after flushing.
Stirring test: put the nonwoven fabric into a stirrer to simulate the impact of water flow and observe its decomposition.
2.2 Strength Test
Although flushable nonwoven fabrics need to have good decomposition properties, they still need to maintain a certain degree of strength during use to ensure that they do not break down or fail prematurely during use. Common strength tests include:
Tensile Strength Test: Evaluates the strength of a nonwoven in the tensile state.
Tear strength test: to assess the tear resistance of a nonwoven when subjected to a tearing force.
2.3 Water absorption test
Water absorption is an important performance indicator for dispersible nonwoven fabrics in products such as wet wipes. Through the water absorption test, the water absorption speed and capacity of nonwoven fabrics can be evaluated to ensure that they can effectively absorb liquid in actual use.
2.4 Microbiological Test
As dispersible nonwoven fabrics are commonly used in hygiene products, microbiological testing is an important part of ensuring their safety. The test mainly evaluates whether there are harmful microorganisms in the nonwoven fabric to ensure that it meets hygiene standards.
III.How to ensure product quality
To ensure the quality of dispersible nonwovens, manufacturers need to take the following measures:
3.1 Strict adherence to testing standards
Manufacturers should conduct tests in strict accordance with international and industry standards to ensure that the product meets the requirements in terms of disintegration properties, strength, water absorbency and microbiological safety.
3.2 Regular Quality Testing
In addition to testing during the production process, manufacturers should also conduct regular quality tests on finished products to ensure that each batch of products meets the quality standards.
3.3 Optimisation of production processes
By continually optimising the production process, manufacturers can improve the uniformity and stability of their products, thereby enhancing overall quality.
3.4 Customer feedback and improvement
Manufacturers should actively collect customer feedback, keep abreast of product performance in actual use, and make improvements based on the feedback in order to continuously improve product quality.
IV.Conclusion
As an environmentally friendly material, the market demand for flushable nonwovens is growing. However, to ensure product quality, manufacturers must strictly follow relevant testing standards and take effective quality control measures. Through scientific testing and strict quality control, enterprises can produce high-quality flushable nonwoven fabrics to meet market demand and win consumers' trust.
