The ability to resist wetting by water. Web
1) The wide film of fibres that is delivered from a card. 2) A similar product of other web forming equipment such as that formed by air or water deposition and used to make nonwoven fabrics. 3) A term loosely applied to lightweight nonwoven fabrics. Weaving
The process of interlacing two or more sets of yarns at right angles to form a fabric. Web consolidation
The process by which the fibres or fibrous materials are interlocked in order to provide the integrity or strength desired in the fabric structure. Web formation
The process by which individual fibres or fibrous materials are arranged in order to bring about the physical properties desired in the fabric structure. Weight
The force experienced by a body as a result of the earth's gravitational force. Any similar force with which a body tends to a centre of attraction. The heaviness of a body regarded as a property of it. Wet back test
The purpose of the test is to examine the ability of a diaper coverstock to resist the transport back onto the skin of a liquid that had already penetrated the coverstock. The test is designed for coverstock comparison purposes only and is not intended to simulate in-use conditions of finished products. Wet forming
Formation of a web by filtering an aqueous suspension of fibres onto a screen belt or on to a perforated drum. Wetlaying
Forming a web from an aqueous dispersion of fibres by applying modified paper making techniques. Wetlaid
A fibre web produced by the wetlaying technique. Wetlaid nonwoven
Wetlaid web bonded by one or more techniques to provide fabric integrity. Wet milling
The grinding of a solid material in the presence of a liquid, normally water. Wet strength
The resistance of a fabric to being torn when it is wet. Usually compared to its strength when dry. Wicking
Transport of liquid within an absorbent fabric, along the thickness of the fabric and within the plane of the fabric. Wood pulp
Cellulosic fibres used to make viscose rayon, paper and the absorbent cores of products such as diapers, sanitary towels and adult incontinence products. Workers
Rolls in the carding process that comb out and disperse the fibre bundles.
