The anti-aging non woven fabric has been recognized and applied in the field of agriculture. The anti-aging UV is added in production to provide excellent protection for seeds, crops and soil, prevent water and soil loss, insect pests, damage caused by bad weather and weeds, and help ensure harvest in every season.
What are the advantages of anti-aging UV?
1. High bursting strength; Good uniformity helps with water infiltration;
2. Excellent durability; Durable anti-aging property; Frost and frost prevention;
3. Economic and environmental protection; Automatically degradable.
Test method for aging resistance of non-woven fabrics
During the use and storage of non-woven fabrics, due to various external factors, certain properties may gradually deteriorate, such as deterioration, hardening, loss of luster, and even decrease in strength and rupture, resulting in loss of use value. This phenomenon is called non-woven fabric aging. Due to different usage environments, the requirements for aging resistance of non-woven fabrics also vary. The testing of aging resistance is the use of artificially created natural environments to measure or observe changes in the properties of non-woven fabrics, but many changes are difficult to quantify. Generally, the strength changes before and after the changes are tested to evaluate the quality of the aging resistance of non-woven fabrics. In testing aging resistance experiments, various factors cannot be considered simultaneously, and only the role of one factor can be highlighted while excluding other secondary factors, thus forming many methods for testing aging resistance performance.
Anti aging standard of non-woven fabrics
The anti-aging properties of non-woven fabrics are closely related to additives. Nonwovens manufacturers often add antioxidants, ultraviolet absorbers and other substances to improve the anti-aging performance of non-woven fabrics. At present, the commonly used anti-aging standards of non-woven fabrics in China include Q/320124 NBM001-2013, ISO 11341:2004, etc. These standards determine the testing methods and indicators for non-woven fabrics under different conditions, providing reference for consumers to choose products with good durability.
How to select appropriate anti-aging non-woven fabrics
Choose non-woven fabrics with good durability
When choosing non-woven fabric, factors such as material, weight, strength, and density should be considered. High quality non-woven fabrics usually have a soft texture, a smooth surface, and no obvious pores. Its weight and strength are correspondingly high. At the same time, products with anti-aging agents, ultraviolet absorbers and other substances added can better maintain the quality and service life of their products.
Determine the application scenario
In terms of agriculture, if used for crop cover, consideration should be given to its UV resistance, insulation, breathability, and other properties. For example, in areas with strong sunlight, non-woven fabrics with outstanding UV resistance are needed to protect crops from excessive UV exposure; If used for winter insulation, attention should be paid to its insulation performance.
In the field of architecture, when used for waterproofing membrane protection, the waterproofing, weather resistance, and compatibility with waterproofing membranes of non-woven fabrics need to be considered. For example, it is necessary to ensure that non-woven fabrics can maintain good performance under different climatic conditions, will not be damaged by temperature changes, rainwater erosion, etc., and can be tightly adhered to waterproofing membranes to provide effective protection.
Medical and health field: for the production of medical masks, protective clothing, etc., non-woven fabrics are required to have good anti-aging performance to ensure the stability of the product during storage and use. At the same time, they are also required to have the characteristics of sterility and good permeability to ensure the safety and comfort of medical staff and patients.
In the field of environmental protection, when making eco-friendly bags, consideration should be given to their durability, reusability, and environmental friendliness. The non-woven environmental protection bag with good anti-aging performance can be used for a longer time to reduce the burden on the environment.
Industry: For industrial filter cloth, packaging materials, etc., appropriate anti-aging non-woven fabrics should be selected according to specific industrial environment requirements. For example, in environments with corrosive substances, non-woven fabrics need to have corrosion-resistant properties.
Consider environmental factors for use
Climate conditions: There are significant differences in climate between different regions, such as strong sunlight, high temperatures, and high humidity in tropical areas, which require high resistance to ultraviolet radiation and humidity for non-woven fabrics; In cold regions, non-woven fabrics need to have good cold resistance and not become brittle at low temperatures.
Exposure time: If the non-woven fabric will be exposed to the outdoor environment for a long time, it is necessary to select a product with strong anti-aging performance to ensure that it can maintain good performance for a long time. On the contrary, if it is only used for a short time or in an indoor environment, the requirements for anti-aging performance can be appropriately reduced.
Conclusion
The anti-aging of non-woven fabric is an important factor affecting its service life and quality. This article introduces the anti-aging standards of non-woven fabrics, the methods of selecting non-woven fabrics and the maintenance methods of non-woven fabrics, hoping to provide some references for consumers to choose high-quality non-woven fabrics.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
