Melt-blown nonwovens are produced by extruding melted polymer fibers through a spin net or die consisting of up to 40 holes per inch to form long thin fibers which are stretched and cooled by passing hot air over the fibers as they fall from the die. The resultant web is collected into rolls and subsequently converted to finished products. The extremely fine fibers (typically polypropylene) differ from other extrusions, particularly spun bond, in that they have low intrinsic strength but much smaller size offering key properties. Often melt blown is added to spun bond to form SM or SMS webs, which are strong and offer the intrinsic benefits of fine fibers such as fine filtration, low pressure drop as used in face masks or filters and physical benefits such as acoustic insulation as used in dishwashers. One of the largest users of SM and SMS materials is the disposable diaper and feminine care industry. [6] Spunbond nonwovens [ edit ] Overall, non-woven fabrics offer a diverse range of properties and applications, making them an important part of the textile industry and various other sectors.. A recent patent has been assigned to Fiberweb Corovin GmbH for manufacture of polyethylene-based, soft nonwoven fabrics as well (Ref.2). The abstract states:

The wastewater industry is encouraging a standard definition (rather than one which varies with each producer) of flushability, including dispersibility, and third-party assessment or verification, such as by NSF International. They believe that products should be safe for both septic and sewer systems (flushable and dispersible, respectively). [14] Orange County Sanitation District has created a campaign, "What 2 Flush", which recommends flushing only the "three P's—pee, poop and [toilet] paper". [15] See also [ edit ] Spunbond nonwovens are made in one continuous process. Fibers are spun and then directly dispersed into a web by deflectors or can be directed with air streams. This technique leads to faster belt speeds, and cheaper costs. Several variants of this concept are available, such as the REICOFIL machinery. [7] PP spunbonds run faster and at lower temperatures than PET spunbonds, mostly due to the difference in melting pointsTo my understanding, Corovin is a technology using to manufacture Nonwoven fabric. These fabric could either be polypropylens or polyesters, yet technique is first develop for polypropylene (Ref.1). Following is the phrase I borrowed from the book (p. 134): hydroentanglement: mechanical intertwining of fibers by water jets (also called spunlace) [11] [12] Absorbency:** Depending on the fibers used and the manufacturing process, non-woven fabrics can exhibit different levels of absorbency. This makes them useful for products like wipes, medical dressings, and more. Breathability:** Non-woven fabrics can be designed to be breathable, which makes them suitable for products like disposable diapers and medical garments.

Customizability:** Non-woven fabrics can be engineered to have specific properties such as softness, stretch, texture, and more, depending on the intended application. Spunbond has been combined with melt-blown nonwovens, conforming them into a layered product called SMS (spun-melt-spun). Melt-blown nonwovens have extremely fine fiber diameters but are not strong fabrics. SMS fabrics, made completely from PP are water-repellent and fine enough to serve as disposable fabrics. Melt-blown is often used as filter media, being able to capture very fine particles. Spunbond is bonded by either resin or thermally. Regarding the bonding of Spunbond, Rieter [8] has launched a new generation of nonwovens called Spunjet. What 2 Flush: Know what should go down the drain that is sewer safe", Orange County Sanitation District. Geotextiles:** Used in construction and civil engineering for erosion control, drainage, and road stabilization. chemical bonding (wetlaid process): use of binders (such as latex emulsion or solution polymers) to chemically join the fibers. A more expensive route uses binder fibers or powders that soften and melt to hold other non-melting fibers together

The industry has attempted to define " flushability". They encourage voluntary testing of flushability by producers. They also encourage clear marking of non-flushable products as "No Flush" (rather than fine print on the bottom of products) including creating a "No Flush" logo. [13] Versatility:** Non-woven fabrics can be made from various types of fibers, such as natural fibers like cotton or synthetic fibers like polyester. This allows for a wide range of applications and uses. Strength and Durability:** Non-woven fabrics can be engineered to have specific strength and durability properties, making them suitable for various applications where strength is important.
