How to improve the performance of non-woven fabrics through materials

At present, the application of non-woven fabrics has spread to all aspects of daily life and industrial production, so different properties are needed to meet the requirements of market and industry applications. In addition to materials, equipment and processes, the selection and use of various additives can also give non-woven fabrics more powerful characteristics and develop high-standard materials and products. Now let me take you to take a look at some of the black technologies used in non-woven fabrics.


Customized new materials provided by Americhem


Americhem recently developed a new version of mBrace softening additive in the non-woven fabric market. This is in addition to the initial mBrace softening additive, which enables non-woven fabric manufacturers to achieve the desired softness by reducing the coefficient of friction or sliding. The new version currently under development gives the feel of cotton textiles. The thermal stability of this product helps manufacturers produce softer-touch materials without affecting other properties. At the same time, the product can be customized according to the manufacturer's specific requirements, allowing the softness level to be set, and the utilization rate is more flexible. This can help users to ensure the best softness of the product while eliminating any influence from the processing process.


AGC develops finishing agent for medical non-woven fabrics


Medical products such as surgical gowns, masks, drapes and packaging must be able to repel liquids, oils and alcohol, and quickly remove stains during washing. These properties are achieved by coating the non-woven fabric with a water repellent agent before making the garment. However, water repellents have had the problem of longevity because they may decompose to form perfluorooctanoic acid (PFOA). In order to solve this problem, AGC Chemicals Americas has developed AsahiGuard AG-E600, a high-performance, PFOA-free waterproofing agent with better environmental protection effects and biocompatibility characteristics.


BASF BASF launches water-based acrylic adhesive


BASF has introduced a new type of non-woven fabric that uses Acronal 2434 to meet the requirements of high thermal stability. Acronal waterborne acrylic and styrene acrylic dispersions can be used as adhesives in high-quality architectural coatings, adhesives, structural and fiber bonding applications. Acronal redispersible powder acts as a co-binder in dry-mix mortars and improves its performance in a wide range of construction applications.


Eastman Eastman Microfiber realizes product diversity


Eastman has developed Cyphrex microfibers to meet the various performance requirements of increasingly demanding non-woven applications, especially those manufacturers of wet-laid non-woven fabrics and specialty papers, who can benefit from improved strength , Uniformity and reproducibility. Customized development also involves a variety of potential end uses, including but not limited to filtration, packaging, high-durability paper, wallpaper, and batteries.


Exxon Exxon Expands Polymer Field


Exxon Brothers Chemical has withdrawn its new low-viscosity Vistanmaxx high-performance polymers for sanitary and assembly hot-melt applications.


Vistamaxx high-performance polymers enable companies to develop innovative solutions to improve product performance and production efficiency. It also has potential sustainable development advantages, which can thin the packaging film, reduce the amount of material, and reduce the thickness of the rigid packaging to increase the strength of the product to avoid damage or waste. At the same time, he also achieved a lower processing temperature, thereby reducing energy consumption.


Omnova provides binders and finishing agents


For non-woven fabrics, many factors affect the choice of fiber, fabric forming and net-fixing process, including process efficiency, product performance, application requirements, consumer needs and cost of use. Omnova's polymer recombination and finishing/surface treatment provide greater flexibility at the moment of decision making for important processes. For the currently used volatile raw materials, non-woven fabric manufacturers are looking for flexible combinations of different fibers and polymers. In spunlace wipes, the raw material mixture is usually composed of 50% absorbent fiber (polyester or polypropylene), which depends on the price change of the raw material. At present, the percentage of viscose has been reduced in Yuduo wipes. , Which will have a negative impact on absorption capacity and softness.


In addition, OMNOVA's anti-aging agents and elastomer modifiers are used in the rubber component of elastic waistbands and other stretchable materials to give the product elasticity and anti-aging properties.
