非织造材料与工程专业英语词汇（P）——非织造论坛整理发布，第一无纺布网！PPaddingApplying a liquid or paste to a web by passing it between squeeze rollers or by dipping it in a bath that carries the liquid or paste.Parallellaying
Forming a web in such a way that the fibres or filaments are laid in directions roughly parallel with the machine direction.Parallellaid
A web where the fibres or filaments are laid roughly parallel to the machine direction.Permeability
The ability to be penetrated by liquids or gases.Physical bonding
A method of bonding fibrous webs by physical means: mechanical and thermal treatments.Picker
A machine that separates staple fibre and forms it into a lap so that it can be fed to a card.Pigment
A coloured or white substance that is insoluble and finely divided. Used to colour or to deluster a fibre, fabric or plastic.Pilling
The tendency of fibres to come loose from a fabric surface and form balled or matted particles of fibre.Plastic
A polymer with its additives. Also the ability to be deformed and moulded.Plasticiser
Chemical that imparts flexibility, stretch and workability to a fabric or a plastic.Plies
Layers of web, fabric or components of a laminate.Point bonding
Using heat and pressure in a discrete predetermined pattern to bind thermoplastic fibres to form a nonwoven fabric.Polyester fibre
A manufactured fibre in which the fibre forming substance is any long chain synthetic polymer composed of at least 85% by weight of an ester of dihydric alcohol and terephthalic acid. The polymer is produced by the reaction of ethylene glycol and terephthalic acid or its derivatives.Polythylene fibre
A manmade fibre made of polyethylene, usually in monofilament form although work has been done on continuous filament yarns and staple. Ethylene is polymerised at high pressures and the resulting polymer is melt spun and cold drawn. It may also be dry spun from xylene solution.Polypropylene fibre
An olefin fibre made from polymers or co-polymers of propylene. Polypropylene fibre is produced by melt spinning the molten polymer followed by stretching to orient the fibre molecules.Polymer
A liquid or solid substance made by chemically linking macromolecules together in chains. High polymer denotes substances made from very long chains. Crosslinked polymer describes a substance in which there are molecular links between chains. Polymerisation is the process for making these polymers.Plasma
A gas of positive ions and free electrons with approximately equal positive and negative charges.Precipitation
The action of a solid or liquid separating from a solution because of a chemical or physical process or change that has rendered it insoluble.Print bonding
A method of thermally or chemically bonding a web in discrete regions of the web according to a predetermined pattern.Pulp(chemical)
The end product of cooking wood chips, cotton or some source of cellulose, with water and appropriate chemicals.【推荐：非织造材料与工程专业英语词汇汇总】文档下载：
