Staple fibers and continuous fibers are combined through the assistance of mechanical, chemical, solvent, or heat treatments to create a nonwoven fabric. This material bears resemblance to fabric and evokes associations with textiles like felt. The term "staple fibers" refers to shorter fibers, whereas "continuous fibers" are longer in comparison to staple fibers. Frequently, nonwoven fabrics undergo reinforcement to enhance fabric strength.
Polypropylene (PP) boasts a natural resistance against stains and wear, rendering it a durable choice. The fabric's remarkable chemical inertness positions it as an optimal selection for applications in acidic surroundings. The fabrication of spunbond nonwoven fabric involves intricately spinning and dispersing fibers into a web-like configuration, with the option of harnessing airstreams to achieve enhanced dispersion.
Selection of fibers to blend into nonwoven fabric is a meticulous process driven by material properties and intended applications. The anticipated performance of the fabric hinges upon the specific fibers chosen to either compose or fortify the nonwoven fabric. Diverse threads are meticulously employed in varying proportions to achieve an optimal amalgamation. Polyester stands as a conventional choice for nonwoven fabric, often synergized with olefin and nylon to augment strength. The introduction of cotton and rayon fibers serves to elevate material absorbency. Additionally, acetate, vinyon, and acrylic fibers are strategically combined with other counterparts.
It is worth noting that the employment of virgin fibers carries a higher cost, consequently influencing the final product's price point. Both the selected fibers and the chosen fabrication techniques play an integral role in determining the ultimate cost of the nonwoven fabric.
Non-woven fabrics are classified based on different method of production. Here are some common classifications and types of non-woven fabrics:
Spunbond Non-woven: Produced by extruding molten polymer through fine nozzles and then stretching and solidifying the filaments. It results in a fabric with good tensile strength and stability.
Spunlace Non-woven: Produced by high-pressure water jets entangling the fibers, creating a fabric with a soft texture often used in wipes and medical applications.
Wet-laid Non-woven: Fibers are dispersed in water, and then a bonding agent is added to bind them together. This process is similar to traditional papermaking and produces fabrics with good absorbency.
Meltblown Non-woven: Similar to spunbond, but the fibers are much finer and are directly blown onto a moving conveyor belt. Meltblown fabrics are often used for filtration applications due to their high surface area and fine fibers.
Hydrophilic Nonwoven Fabric: The hydrophilic nonwoven fabric is used to manufacture sanitary material and other medical grade or surgical material. The material is soft to touch and sensitive to skin.
Heat Bounded Non Woven Fabric: The primary binding process for this nonwoven fabric is heated. The fiber webs are taken together with adhesives and treated with high heat. The bonds in the layers of fibers get melted by applying heat. On cooling, the web of fibers gets combined into a single nonwoven fabric.
In today's modern society, nonwoven fabrics have found themselves indispensable across a myriad of applications. The surge in their utilization can be attributed, in part, to their economical nature. Notably, the eco-friendly disposition of nonwoven fabrics renders them a superior alternative to conventional plastics. While nonwoven fabric's durability concerns render it less suitable for garment production, its merits shine remarkably in the realm of disposable medical equipment manufacturing. Gradually and consistently, nonwoven fabric is overtaking polyurethane foam in various applications. This versatile material lends itself well to crafting items like bags and assorted supply materials, boasting an added advantage of being resistant to water penetration, enhancing its utility.
