Iyo inonzi yakapfava uye yakagadzika mubato wemachira inonzwa subjective inowanikwa nekubata machira neminwe yako.Kana vanhu vachibata machira, zvigunwe zvavo zvinotsvedza nekukwesha pakati pemafiber, machira eruwoko kunzwa uye kupfava zvine hukama hwakati necoefficient of dynamic friction of the fibers.Mukuwedzera, iyo fluffiness, plumpness uye elasticity ichaitawo kuti ruoko runzwe rwejira runyoro.Zvinoratidza kutikunzwa ruokoyakabatana nepamusoro pekugadzirwa kwefiber.Tora surfactant softeners semuenzaniso.Nheyo yekushanda yezvinyoro-nyoro inowanzofungidzirwa kuti inotsanangurwa nenzira mbiri.Zviri nyore kuti ma surfactants ave neanotungamirwa adsorption pamusoro pemafibhi.Kunyangwe iwo ma surfactants adsorbed pane akajairwa akasimba nzvimbo inoderedza kushushikana kwepasi, faibha pamusoro nzvimbo yakaoma kuwedzera.Uye machira machira anogadzirwa nemutsara macromolecule ine yakakura kwazvo chaiyo nzvimbo uye yakarebesa chimiro, iyo ine molecular cheni ine yakanaka kuchinjika.Mushure mekutora ma surfactants, tension yepasi inodzikira, izvo zvinoita kuti fiber ive nyore kuwedzera kumusoro uye kurebesa kureba.Kuitira kuti machira ave fluffy, akapfava, elastic uye akapfava.Iyo yakasimba iyo adsorption ye surfactant pamusoro pefiber pamusoro uye zvakanyanya kuderedzwa kwefiber pamusoro tension, iyo yakapfava mhedzisiro inova pachena.Cationic surfactants inogona kushambadzirwa zvakanyanya pafiber pamusoro nemagetsi emagetsi simba (Mazhinji mafiber ane negative surface charge).Kana boka re cationic rakatarisana nefiber uye boka re hydrophobic rakatarisana nemhepo, mhedzisiro yekuderera kwefiber surface tension yakakura.
Kunyudzwa kwevanogadzika pamusoro pefiber pamusoro kunoumba firimu rakatetepa remapoka e-hydrophobic akarongeka kunze, izvo zvinoita kuti kupesana pakati pemafiber kuitike pakati pemapoka ehydrophobic anotsvedza achipokana.Nekuda kwemafuta emapoka ehydrophobic, iyo friction coefficient inoderedzwa zvakanyanya.Uye iyo ketani ye hydrophobic boka irefu, inotsvedza zviri nyore.Kudzikira kwe friction coefficient zvakare kunoderedza flexural modulus uye compressing simba remachira, zvichikonzerakubata.Panguva imwecheteyo, kuderera kwe friction coefficient kunoita kuti zvive nyore kuti tambo dziite nyore kana jira rinoiswa pasi pemasimba ekunze, kuitira kuti kushushikana kupararire uye simba rekubvaruka rivandudzwe.Kana panguva yekushanda, mafiibhi akaiswa pasi pesimba rakasimba anowanzo dzokera kune yakagadzikana zviri nyore, zvichiita kuti mubato upfave.Kana vanhu vakabata mafiibhi, static friction coefficient inoita basa rakakosha mukupfava kwejira.Asi tichitaura, kupfava kweruoko kunzwa kwemafibhi kune hukama zvakanyanya nekudzikiswa kweiyo static friction coefficient.
Kupfavisa kupedzisa mumiririri kazhinji kunoreva komisheni inogona kushambadzwa pafiber uye inotsvedzerera pamusoro pefiber, ichiwedzera kupfava kwefiber.Parizvino, kune marudzi maviri ezvinowanzoshandiswasoftening agent, sema surfactants uye ma-high-molecular softening agents.High-molecular softening agents anonyanya kusanganisira silicone softeners uye polyethylene emulsions.
