E Elasticity
The ability of a strained material to recover its original size and shape immediately after removal of the stress that causes deformation. Elastomers
Polymers having the rubbery qualities of stretch and recovery. Electrostatic web
A web produced by an electrostatic process. Forming a web of fibres, especially BONDING microfibres, by means of an electrostatic field from a polymer solution or emulsion, or from a polymer melt. Embossing
A process whereby a pattern is pressed into a film or fabric, usually by passing the material between rolls with little clearance and where one or both rolls have a raised design. At least one of the rolls is
usually heated. Emulsion
A suspension of finely divided liquid droplets within another liquid (see DISPERSION). Entanglement
A method of forming a fabric by wrapping or knotting fibres in a web about each other by mechanical means, or by use of jets of pressurized air or water, so as to bond the fibres (see MECHANICAL BONDING). Extrusion
A process by which a heated polymer is forced through an orifice to form a molten stream that is cooled to form a fibre. Examples of this process are Polypropylene and Polyester. Alternatively, a solution of polymer can be forced through an orifice into a solvent that causes the fibre to solidify. Examples are Kevlar and rayon. 文档下载: |
