FTIR Study of Hydrophilic Non Woven Fabric
Hydrophilic non woven fabric is a type of fabric that has been treated with a hydrophilic agent. This treatment is typically applied at a concentration of 0.5 grams per square meter. This treatment improves water-repellent properties and makes it a better material for many different applications.
FTIR analysis
The FTIR spectroscopy technique is a powerful tool for determining the chemical composition of a hydrophilic non woven fabric. It is also useful for determining the durability of modifiers on the fabric surface. Figure 5a and b shows the spectra of a control and a treated fabric. Both of the spectra were recorded using a Bruker spectrophotometer. The FTIR spectra of the fabrics show OH bands at 3329 cm-1, indicating free hydroxyl and OH groups on the fiber surface. These bands are slightly smaller because of the bonding with alkoxysilyl groups.
Hydrophilic non woven fabrics were modified using graft polymerization, which is a general method for polymer modification. The grafting of acrylic acid, using varying irradiation doses and monomer concentrations, provided hydrophilic carboxylic acid groups. The grafted copolymer was studied with X-ray photoeletron spectroscopy and Fourier Transform Infrared spectroscopy (FTIR) and X-ray spectroscopy (XPS). During testing, the fabric was found to remove heavy metal ions and other impurities from air.
Non-woven fabrics have gained popularity as oil-water separators because of their light weight, flexible, and corrosion-resistant properties. Additionally, they have several other applications, including air filtration, the reclamation of domestic wastewater, and the treatment of irrigation water.
Chemical treatment
The chemical treatment of hydrophilic non woven fabric has become an important research field. Here https://www.diapernonwoven.com/ are many benefits to this type of fabric, including the ability to repel water and oil. However, the process of developing these fabrics is expensive and involves the use of hazardous compounds. Therefore, the aim of the research is to fabricate such fabrics without relying on harmful chemicals.
The end-use properties of nonwovens depend on the fibers, fabric structure, and other properties. There are a variety of possible modifications that can improve these properties. A hydrophilic finish can be applied on the nonwoven fabric’s surface to improve the emulsion quality, reduce surface tension, and provide static protection. This coating can be applied using a spin finish, spray, kiss roll, or dip bath application.
After preparing the nonwoven fabric, it is spray-tested to measure its water repellency. The results are presented in Fig. 17. An AATCC value of 100 means that water drops will be completely repelled from the treated nonwoven fabric’s surface. If it falls below this value, the water drop will stick to the fabric’s surface and cause some slight wetting. This rating is the standard for water repellency.
Molecular structure
The molecular structure of hydrophilic non woven fabrics depends on the chemical composition of the fibers and the treatment used to increase their wettability. Ordinary polypropylene, for example, does not have enough polar groups or oxygen on its surface to interact with water strongly. As a result, it will appear to float in water. This is because water cannot penetrate adjacent fibers. Therefore, treatments to increase the wettability of fibers will impact the wet-laid nonwoven processing.
Nonwovens can be made from almost every fibre. The major properties of these fibres determine the inherent absorbency and other properties. They also vary in terms of fibre denier and polymer type. The latter influences the amount of void space and capillary dimensions per unit mass.
Nonwovens can be treated by applying plasma to increase their wettability. Plasma treatments also increase the surface roughness of the fibers. These treatments can be applied to a variety of nonwoven applications, including the printing industry.
End uses
There are many end uses for hydrophilic nonwoven fabrics. These fabrics are useful in a variety of applications, including apparel, hygiene and personal care, medical and industrial protective clothing, automotive applications, and filtration. Various manufacturing techniques can be used to create nonwoven materials with the desired end uses.
Nonwoven fabrics can be fabricated into air filters for HVAC systems. They can also be used as sanitary towels or disposable wipes. In addition, they are an excellent substitute for cotton batting in quilts. Some of the most important applications for this material include pollen and bacteria control. It is also a popular material for medical workers.
Many industrial and household applications for nonwovens are already underway. They are used in everything from surgical gowns and masks to sanitary towels and pet pads. They are also used in the automotive, aerospace, and home tech industries. The breathability and other properties make them an ideal material for these applications.
