PROPERTIES OF SPUNLACED FABRICS

Spunlaced fabrics show high drape, softness and comfortable handle because more fiber entanglement leads to increased strength without an increase in shear modulus. It has also been shown that there is a relationship between absorbency capacity and hydroentangling energy used. An increase of hydroentangling energy results in a decrease of absorbency capacity and absorbency rate. Shear modulus remains low and is virtually independent of the degree of entanglement. The softness of the fabric is explained by the fact that the entangled structures are more compressible than bonded ones, as well as having mobility and partial alignment of fibers in the thickness direction. The absence of a binder is seen to result in a fabric with yarn-like fabric intersections composed of "pseudoyarns". The pseudoyarns are "more highly intereconnected than yarns of conventional fabrics because individual fibers can migrate from one pseudoyarn to another. This tends to stabilize the intersection". This pseudoyarn structure seems to be the reason for good dimensional stability, which is also accountable for drape.

Softness, and good strength/weight properties of the fabric, pilling and abrasion behavior.

The strength of hydroentangled fabrics is lower than that of woven and higher than that of knitted fabrics, whereas the wash durability is considerably lower than that of woven or knitted fabrics.

Prdouct Process:

Spunlacing is a process of entangling a web of loose fibers on a porous belt or moving perforated or patterned screen to form a sheet structure by subjecting the fibers to multiple rows of fine high-pressure jets of water .Various steps are of importance in the hydroentangling process.

While some of them are typical in a nonwoven process, some of them are unique to the process of spunlacing. The steps characteristic for producing hydroentangled nonwoven fabric include:

• Precursor web formation
• Web entanglement
• Water circulation
• Web drying
• 
•
