Fibre Selection for Spunlace Processing
topic
Spunlace fibre selection requires fibres with adequate length for mechanical entanglement typically above 25 millimetres, with viscose, lyocell, cotton, polyester, and polypropylene being the primary spunlace fibres, while speciality spunlace processes incorporate wood pulp in high pulp content wipes, aramid fibres for protective spunlace, and biopolymer fibres for biodegradable wipes meeting increasing sustainability requirements in personal care markets.
Role
Determines the absorbency, softness, strength, and environmental profile of spunlace fabrics through fibre type selection that governs the entanglement potential and intrinsic fibre properties that cannot be modified by the bonding process, with fibre selection being the primary design variable for spunlace product differentiation across the wipes, medical, and apparel markets where fibre type drives both performance and consumer sustainability perception.
