Handle-o-meter:
A machine that measures the “handle” (i.e., combination of surface friction and flexibility) of nonwoven fabrics used in disposable hygiene.
The greater the flexibility with reduced friction, the softer the nonwoven fabrics appear.
Hot-melt:
This fast-drying nonvolatile adhesive is applied hot in the molten state.
It does not negatively impact the feel of softness, drape or the visual appearance of the materials after bonding.
Hot melt adhesive polymers traditionally used in the disposable hygiene products include ethylene/vinyl acetate copolymers (EVA), amorphous polyalphaolefins (APAO), styrenic block copolymer (SBC) based adhesives and polyolefin.
Lamination:
The process of one substrate being coated with hot-melt and being combined with another substrate between nip rolls.
The result is increased softness and reduced noise with good strength and mechanical resistance compared to a product that uses thermabonding.
Loft:
The relationship between the air and fiber structure in a nonwoven fabric.
Disposable hygiene products made with *high-loft fabrics* tend to be thick, fluffy and have an appearance of softness.
Nip rolls:
Mechanical rollers are used to press two or more sheets together to form a laminated product.
Noisy:
Disposable hygiene products that are noticeably heard when removed from the package and during use can be perceived as not being soft because the undesirable sounds they make are often associated with stiff and rigid materials.
Nonwoven:
A textile-like material made from short fibers and/or long continuous fibers bonded together by chemical, mechanical or thermal methods.
Oily:
In some regions, the excessively slick texture of raw materials, surface treatments and slip agents used in the production of disposable hygiene articles increases the perception of product softness.
