Molecular formula : MW : CAS :
nature : short wet strength. Fiber refers to the wet (soaking in water completely balanced state) Determination of the intensity. Different from the fiber during the dry state of the intensity -- intensity dry state (stem strength, dry strength). General hydrophilic fibers due to water-absorbent after the plasticization lead to secondary structural damage, making them wet strength Pi intensity markedly lower. If viscose fiber, its roots wet strength intensity by 30% -50%. But there are also wet strength Pi intensity examples, such as the Department of natural cellulose fibers (cotton, linen), which is due to the high tectonic (micro-fiber, etc.) with particularity a more important role due. Most are hydrophobic synthetic fibers, so they dry, wet or nearly equal intensity. Dry Strength / wet strength ratio, known as wet and dry strength ratio, the value of all properties in fiber occupies an important position.
