Hygroscopicity - nayo ... hygroscopicity fibers, mbatya

Ndiri chokwadi vazhinji vakanzwa shoko iri uye zvichida kunyange vakashamisika sei zvakanyorwa uye zvazvinoreva. Asi haasi munhu wose anoziva chokwadi kuti zivo zvivako nezvinhu zvokunyama kunogona kubatsira muupenyu hwezuva nezuva. Ndicho chikonzero tichifanira kumuziva zviri nani.

tsananguro

Hygroscopicity - pfuma iyi chero mashoko kupinza uye kuramba mwando kubva mumhepo. Vamwe vanogona kuvhiringidza tsamba "g" iri chikamu shoko rokutanga, nokuti isu tose tinoziva kuti akaoma okuti chokuita nemvura uye kazhinji kutanga chivakashure "hydro". Asi pano ndiwo zvishoma chimwe chinhu. Hygroscopicity rinobvumira Absorção de Água nezvinhu ane chete mvura iri sprayed mumhepo sezvo pamwando, uye saka vanoda zvakasiyana zvachose yakatarwa-pamusoro bhokisi. "Hygro" zvinoreva kuti shoko riri akarondedzera mwando. Hazvina nyore.

Takakurukura tsanangudzo, uye zvino ndiyo nguva yokuti uzive chii chaizvoizvo ishoko rinoreva. The mumhepo yakatipoteredza ane zvimwe mwando kugutsikana - nezvazvo, kunyange mamiriro okunze. Vamwe fibers vanokwanisa yekubata mvura iyi saka kazhinji kuchinja ehupfumi ayo. Akafanirwa kune hygroscopic mbatya neshangu vanogona kuwana kunyorova kunyange pasina mvura. Mune zvimwe zviitiko, zvakanaka, uye chii - zvakaipa, dzidza pazasi.

Ndezvipi zvinhu zviri hygroscopic?

Munyaya ino tichakurukura munyama. Asi kwete chete vanokwanisa yekubata mwando kubva mumhepo. Hygroscopicity indekisi ane zvinhu Kazhinji zvakakosha kuziva vavaki, fenicha Vagadziri, Vagadziri kunzwisisa michina uye nevamwe vakawanda.

Somuenzaniso, tose tinoziva kuti huni ane porous chimiro, izvozvo anowedzera yayo hygroscopic ehupfumi. Water rakapinza padondo mamiriro deforms izvozvo. Ndokusaka huni midziyo kushanda kuiswa mumakamuri dzakakwirira mwando. Special impregnation ringashandiswa kuderedza hygroscopicity.

No zvisinganyanyi kukosha, uye hygroscopic zvivako zviri kuputira yaishandiswa pakuvaka. Mhepo parumananzombe pores kwemashoko anochengeta kupisa muimba. Asi kana kuputira rikawana dzanyorova, izvozvo pakarepo anorasikirwa zvinokosha ehupfumi ayo. Naizvozvo, zvakashandiswa chinangwa ichi vanofanira risingamboshandisi Absorção de Água. The akakodzera 0%.

Utsanana ehupfumi of jira

zvinhu zvose vane zvakasiyana mumuviri parameters, akadai arambe achirema, simba etc. Asi micheka, izvo vakabva kutendeukira kuva wenguvo zvinhu uye zvimwe zvivako zvinokosha - Utsanana. Ivo kusarudza sei hwomutambarakede kupfeka kubva imwe zvokunyama.

• Breathability. Zita anotaura woga. Nemicheka dzakakwirira breathability vanokwanisa "fema", uye pasi - kudzivirirwa mhepo.
• The mvura mhute permeability. Kugona zvakaitika mwando kubva Mucheka kutora vanonanga ziya uye zvimwe zvinwiwa kubva mumuviri.
• Isapinda. Inochengetedza muviri kubva mvura. chinhu ichi inowedzera zvinyama pachishandiswa siyana pamusoro mishonga uye coatings.
• Pyleomkost. chinhu ichi zvinoita jira kuchengeta zvakanaka inoramba iri kwayo pamusoro. The boleematerial vakasununguka, dzakanga dziri pyleomkosti.

• Yakafadza - mano zvinyama kuunganidza kunofambira mberi magetsi.

Usakanganwa pamusoro kupisa-kudzivirirwa ehupfumi yacho tishu. Kukwanisa ichi kuramba muupenyu muviri tembiricha panguva zviri chando kunze. Uye yokupedzisira pfuma kuzotaura zvizere.

rejira hygroscopicity

Nhamba iyi chokuita Utsanana ehupfumi pamusoro Textiles, izvo zvinozoita kuona ichinyaradzwa imwe zvinhu kana zvasakara. Uyezve, zvinodiwa kuti zvipfeko kunonyanya hakunei chinangwa chawo.

Hygroscopicity - chinonyanya kukosha zvinhu vanokodzera here kana chirimo nguo. Inosimudzira muviri tembiricha uye kuupenyu nokunyanyisa vangadikitira, izvo zvinozoita kuti pave zvinhu zvinenge munhu. Rasa zvakawandisa mwando anosiya dzakakwirira micheka hygroscopic. pfuma iyi unokosha chakarurama kuti Vanoburitsa andapeni nezuva.

Chii chinoratidza nekugona Mucheka yekubata mwando kubva zvakatipoteredza? Pakutanga - kubva fibers icho chinoitwa. Uyezve, kukosha kuri pamberi anodzivirira coatings uye kumbeu DZAKASIYANA.

Types uye hygroscopic fibers

Zvinhu izvo zvakaitwa rejira, vangava dzakasiyana mavambo. Kune dzinongoitika fibers uye chakaita zvokugadzirwa. Chokutanga, ngatimbotaura pamusoro wokutanga. Zvasikwa pachisikigo, kunyange asina pasina kupindira kwevanhu.

Shinda sheared kubva pemhuka dzakasiyana-siyana, kazhinji kushandiswa pakugadzira zvipfeko. Kuti mumwe vaitungamirira micheka mano avo tibatsirwe mwando dzinongoitika. Hygroscopicity shinda fibers anenge 15-17%. Asi pano ndicho mwando Absorção de Água mwero wacho pasi.

Nhamba iyi zviri kupfuura mune dzimwe nzvimbo dzomuviri zhinji. Somuenzaniso, hygroscopicity nedonje ndiyo 8-9 chete%, asi anogona yekubata mwando zvikuru nokukurumidza shinda. Chimwe dzinongoitika zvinhu - yoruchinda vakawana kubva bast faibha. Kukwanisa kwaro tibatsirwe mwando anogona dzinosiyana 12 kusvika 30%.

Chakagadzirwa uye chakaita zvokugadzirwa fibers

Wokutanga mhando zvinosanganisira zvinhu zvinobva dzinongoitika yeimwe. A muenzaniso unoshamisa - viscose. Zvinonzi akasika kushandisa rwokuzvarwa cellulose. Nokuti viscose fibers vaine simba, kupisa nemishonga, uye yakakwirira hygroscopicity, akaenzana vanenge 40%.

Chakaita zvokugadzirwa fibers pave zvibereko mafuta yokucheneswa uye marasha. Izvi zvinosanganisira polyamides. Of fibers izvi pave zvinhu zvenaironi, zvinhu zvenaironi uye anide. Hygroscopicity nezvinhu zvakadaro rakanyatsojeka yakaderera, 3-4 chete%, asi vane simba ravo kana rwakatambanudzwa uye yakasimba chaizvo. Polyester fibers izvo akasika polyester rejira, vane yakakwirira indekisi nokupisa nemishonga uye chiedza fastness. Asi avo hygroscopic usingashandi - 0,4 chete%.

Spandex, inoita kuti Lycra uye Spandex uyewo hwokuratidza kugona kwavo kufungisisa mwando kubva zvakatipoteredza. Kubva apa zvinogona vakagumisa kuti absorbability zvipfeko yakagadzirwa chakaita zvokugadzirwa nezvinhu dererei zvikuru pane zvinhu zvakaitwa micheka zvakasikwa. Asi uku chaizvoizvo kuvamirira?

Hygroscopicity - zvakanaka kana zvakaipa?

Zvose hama. The chete zvinogona kutaurwa pamusoro penyaya yakamutswa pedu. Mumwe anogona kutaura kuti hygroscopic - zvakanaka. Hungu, anobvumira vanhu nyore vapone kupisa, uye vatambi - ndiite zvokusimbisa muviri ari vasununguka ezvinhu. Asi vamwe nyama kunyanya mwando anogona chete kukuvara.

On muenzaniso hita, takawana mvura kuti akazoita insulating ehupfumi nezvinhu. Uyezve, dzimwe nzvimbo dzomuviri dziri akaremara pasi pokudzora unyoro - isu tose tinoziva sei kutambanudza Jersey pashure yokushambidza. The zvinoitirwa, chete muduku kumwero, vangatambura zvimwe zvinhu ari mukuru kwazvo hama mwando. Naizvozvo hakusi nguva dzose zvinoita kutaura nechivimbo kuti hygroscopic micheka - ndicho chinhu ndinoiitawo. Mubvunzo panguva wemapoka imwe zvinhu.

Sei kuona mufananidzo uyu?

Muna 80-ies pamusoro XX remakore muSoviet Union nayo akasikwa GOST 3816-81. Rinotibatsira rondedzero dzokudzidzisa kuti kutsunga kwevamwe Whitehead Textile zvivako kusanganisira hygroscopicity. Heunoi sei zvinoitwa.

Nyanzvi vakatora 5x20 masendimita kukura uye mumwe zvinyama raiiswa ari oga girazi yairema. The chikuru basa iri kuedza - kuziva sei mvura yakawanda yokufungisisa zvinhu pasi zvimwe ezvinhu. Nokuti chinangwa ichi, mharidzo mukombe yakaiswa desiccator umo mwando iri 97-99%. Pashure 4 chasa yokuenzanisira yairema rinoitwa, uye zvadaro pane imwe tembiricha ^vanenge 105-109 C, mashoko chikapwa uye kuona kwayo uremu itsva.

Hygroscopicity indekisi (H) mu kubva muzana tsunga kushandisa nzira: n = (MB - Mc) / Ms x 100, apo MV uye Mc pakugamuchira ukuwo, uremu nyoro uye akaoma micheka.
