Non Woven Rayon Fabric is made from 100% rayon filament or rayon blend. Rayon is a natural fiber that is derived from wood pulp. As a nonwoven fiber it offers the benefits of high absorbency, softness, and comfortable finish. Non Woven Rayon Fabric is easy to dye, offering a wide array of nonwoven color options. Nonwoven rayon is well suited for a host of application needs including medical and hygiene products, cosmetic wipes, agricultural fabric, and more.
Advantages of Non Woven Rayon Fabric
Lightweight
Non Woven Rayon Fabrics are lightweight compared to other fabrics due to raw material polypropylene resin; its proportion is 0.9, and three-fifths of cotton. Due to this, it is preferred over other fabric materials, especially for industrial usage.
Comfort
The Non Woven Rayon Fabric is made up of (2-3D) through the light point hot melt bonding method. Therefore, the finished product gives a soft and comfortable feel.
Non-Toxic
The Non Woven Rayon Fabric is made from food-grade raw materials which are conforming to the FDA, without the presence of other chemical components. Hence, it is concluded as a non-toxic product.
Antimicrobial
The Non Woven Rayon Fabric is known for its water-extractable property and is mildew-free. It can isolate the bacteria present and also worms in the liquid. Hence, it has antimicrobial properties.
Drainage Activity
The water content in Polypropylene chips is completely zero. It does not absorb water, and the water transfer of the finished products is good. It is composed of 100% fibers with porous and air permeability. Hence, the cloth surface can be kept dry and further easily washed.
Antibacterial and Anti-chemical Property
The chemical compound polypropylene is the passive chemical substance; it does not contain moths and has the ability for bacteria and insect isolation in the liquid. Antibacterial, alkali corrosion, and finished products, due to good strength, do not affect.
Physical Properties
The direct spin makes the non-woven fabric of polypropylene into a net with the help of the thermal bonding method. Its strength is far better in comparison to other ordinary staple fibers. It doesn't have directionality, and the longitudinal and transverse strengths are similar.
Environment Friendly
The raw material polypropylene is the major content of Non Woven Fabric. In comparison to polyethylene which is the raw material of plastic bags, it can degrade easily because of the difference in their chemical structures. The chemical molecular structure of polyethylene is stable and cannot be degraded easily; hence it takes more than 300 years for plastic bags to decompose.
The production of Non Woven Rayon Fabrics can be summarized into 3 parts, web formation, web consolidation and finishing.
Web Formation
Above all, the manufacturer extracts filaments and staple fibers from both natural and man-made sources. These fibers are raw materials of Non Woven Rayon Fabrics. Then, machines arrange them in a web directionally or randomly by plural methods, such as carding, air laying, wet laying, melt blowing, submicron spinning, etc. Nowadays, lines of a Non Woven Rayon Fabric tend to integrate web formation with web consolidation.
Web Consolidation
Web consolidation, also called bonding, endows the fiber web with the strength to further cohesion. It can be classified into 3 types, mechanical bonding, thermal bonding and chemical bonding.
Mechanical bonding: Entangle the fibers in the web by improving physical friction. It mainly includes 2 ways, Needle punching and spunlacing.
Thermal bonding: Add fibrous or powdered adhesive into the fiber web. Then the web is reinforced by heating, melting and cooling.
Chemical bonding: Add a chemical liquid into the web as a binder. It strengthens fibers's cohesion and transforms loose fibers into a fabric.
Finishing
Finishing is a treatment to promote the functional properties of Non Woven Rayon Fabrics, such as reliability, reproducibility and hydrophilicity. It can be chemical treatments or mechanical treatments.
Types of Non Woven Rayon Fabric
Staple Non Woven Rayon Fabric
Staple non-woven are made from staple fibres such as cotton, polyester and acrylic. They are short pieces of fibrils (viscose/rayon) that have been cut from the source material. They can be decomposed into shorter lengths to create a softer end product. They are used in a wide variety of applications including industrial, medical, automotive and construction. Therefore, they're very common in bath tissue products such as toilet paper and paper towels. This type of fabric is also used in making diapers due to its absorbent properties and softness against the skin.
Melt-Blown Non Woven Rayon Fabric
A melt-blown fabric is made from a raw material that is melted and extruded into filaments. The filaments are then cooled, collected, and remelted. This process of melting and remelting is repeated until the desired thickness of the web has been achieved. The filaments are collected on a forming wire to form a sheet of flat non-woven fabric. Melt-blown is created when small bundles of thermoplastic filaments (polyethene terephthalate) are extruded through an annular die onto a quenching drum where they fuse together into an entangled mass because heat from friction melts them down as they pass through each other during passage through the nip zone between rotating feed rolls at speeds up to about 800 ft/min (240 m/min).
Spun-Bond Non Woven Rayon Fabric
This is made from polypropylene, a type of plastic. It's lightweight, soft and breathable and can be used for medical applications as well as home and industrial uses. Spun-bond non-woven fabrics are typically used in medical applications because their light weight allows patients to wear them comfortably for extended periods of time without feeling weighed down by them. Additionally, the breathability of spun-bond fabrics makes them perfect for use on sensitive skin or where there's a risk of infection from touching something moist or dirty (such as around wounds). Spun-bond non-woven is made from continuous filaments of thermoplastic polymers, such as polyolefin and polyesters. These filaments are extruded through a spinneret onto foraminous support.
Needle Punched Non Woven Rayon Fabric
Needle-punched non-woven fabric is a fabric made by punching holes into a flat sheet of non-woven fabric. The needle punching process is used to create a fabric with a high density of holes, which can be manipulated to achieve various effects. The process involves passing the material through many needles arranged in parallel rows. These penetrate the fibres and cause them to separate from one another. They're made from any type of material that can be turned into threads and woven together with needles: Cotton rags, paper pulp, synthetic fibres (such as nylon), and more. The strength of needle-punched non-woven comes primarily from the way the fibres are stitched together.
Wet-Laid Non Woven Rayon Fabric
A wet-laid non-woven fabric is made of a fibre matrix that is created by the coalescence of fibres. The fibre matrix is then used to create a three-dimensional web through heating, cooling and other processes called "forming" or "pressing". The regenerated cellulose fibres were then bonded to form a wet web. This process uses water as the process medium for dispersing fibres and bonding them in a network or matrix. A wet laid process uses water as a process medium for dispersing fibres, but can also be used for bonding them together in a network or matrix. The process is also used for bonding fibres together. The method involves the use of a liquid to form tiny individual strands made up of polymer molecules, which are bonded together by adhesive forces and/or hydrogen bonds.
Heat-Sealed Non Woven Rayon Fabric
Heat-sealed non-woven fabric is a type of non-woven fabric that's literally sealed by heat. In this process, heat is applied to a material without melting it, sealing the edges and forming a seal between them. The seal can be made using different methods depending on the type of fabric being used. Heat-sealed non-woven fabrics are used in many applications due to their strength, durability and low cost. They are often used for packaging and industrial products such as filters because of their ability to filter out particulates. Heat sealing allows for patterns to be formed in the joints between pieces of fabric, which increases their strength.
