SPUNLACE NONWOVEN (2007)
Spunlace nonwoven process uses hydro-entanglement for bonding staple fibers; it involves mechanical intertwining of fibers by water jets. As a result, nonwoven fabrics made by this method have specific properties, as soft handle and drapability.
Most commonly, precursors are mixtures of cellulose and man-made fibers like Rayon (Viscose), Polyester and their blends.
Spunlaced fabrics show high drape, softness and comfortable handle because more fiber entanglement leads to increased strength without an increase in shear modulus.
Hydro entanglement is considered to be a highly versatile process because it can be used to produce nonwovens with a broad range of end-use properties.
Spunlace fabrics can be further finished, usually dyed and/or printed, treated with binders to allow for wash durability, or fire retardants can be applied to resist burning. The fabric can be treated by antimicrobial agents to enhance resistance against microorganisms.
Spunlaced fabrics spans from surgical packs and gowns, protective clothing as chemical barriers to wipes, towels and sponges for industrial, medical, food service and consumer applications. The main reasons for wide use of these fabrics in medical applications is based on relatively high absorption abilities. Another important criterion is absence of a binder in the fabric allowing sterilization of the fabric at high temperatures. |

| PROCESS |
|
|
The spunlace process is a nonwovens manufacturing system that employs jets of water to entangle fibers and thereby provide fabric integrity. |
|
CHARACTERISTICS |
|
|
Softness, drape, conformability, and relatively high strength are the major characteristics that make spunlace nonwoven unique among nonwovens |

| POLYMERE (Viscose\Polyester\Blends) |
|
Most commonly, precursors are mixtures of cellulose and man-made fibers. In general, cellulosic fibers are preferred for their high strength, pliability, plastic deformation resistance and water insolubility. Cellulosic fibers are hydrophilic, chemically stable and relatively colorless. Another advantage is that cellulose has an inherent bonding ability caused by a high content of hydroxyl groups, which attract water molecules. As the water evaporates from the fabric, the hydroxyl groups on fiber surface link together by hydrogen bonds. |
|
| PROPERTIES |
|
Spunlaced fabrics are unique among nonwoven fabrics because of the balance achieved between strength and shear modulus. General speaking, spunlaced fabrics rely primarily on fiber-to-fiber friction to achieve physical integrity and are characterized by relatively high strength, softness, drape, conformability and aesthetics closely approaching woven and knitted fabrics

|
| APPLICATIONS |
|
Hydroentanglement is considered to be a highly versatile process because it can be used to produce nonwovens with a broad range of end-use properties. These differences are achieved as a result of a wide range of fibers that are available and also because of the wide range of possible parameter adjustments. The versatility of the hydro entanglement processes is seen as an advantage because this process can be used to combine conventionally formed webs with melt-blown, spunbond webs, paper, other textiles and scrims in order to get a combination of properties that cannot be achieved by the use of a single web.
Spunlace fabrics can be further finished, usually dyed and/or printed, treated with binders to allow for wash durability, or fire retardants can be applied to resist burning. The fabric can be treated by antimicrobial agents to enhance resistance against microorganisms.
The market for spunlaced fabrics spans from surgical packs and gowns, protective clothing as chemical barriers to wipes, towels and sponges for industrial, medical, food service and consumer applications. The main reasons for wide use of these fabrics in medical applications is based on relatively high absorption abilities. Another important criterion is absence of a binder in the fabric allowing sterilization of the fabric at high temperatures. |
