thermoplastique poliyuretan (TPU), i n’a fɔ fɛn min ka bon-}}}} baarakɛcogo sɛgɛsɛgɛli, u be baara kɛ kosɔbɛ ni faniw, farikoloɲanagwɛ minanw, furakɛlifɛnw ani iziniw ye k’a sababu kɛ u ka elastisite ɲuman ye, u be se ka yɛlɛma, u be se ka kemikaliw kɛlɛ, ani u be se ka yɛlɛma. A ka sariyaw be polimeri minanw lɔnniya, fani dilan ani baarakɛcogo ɲumanw don ɲɔgɔn na. Molɛkiliw labɛncogo yɛlɛmani n’a labɛncogo ɲuman fɛ, a be se ka kɛ ni kɛcogo kɛrɛnkɛrɛnninw ye.

I. TPU Fabrics ka mobili dilan cogo ani a ka baarakɛcogo jɔnjɔnw

TPU ka dilan cogo jɔnjɔn be daminɛ n’a ka molekiliw labɛncogo yɛlɛmani ye. TPU be kɛ ni yɔrɔ gwɛlɛw ye (o be kɛ ni disocyanate ani cakɛda yɛlɛmani ye) ani yɔrɔ nɔgɔmanw (min be kɛ ni poliyetiri wala poliyesitɛri ye). O mikrofaziw farancogo lo y’a ka baara caaman jusigilan ye. O yɔrɔ gwɛlɛw be gɛlɛya, fanga ani funteni basigili di, k’a sɔrɔ yɔrɔ nɔgɔmanw be se ka yɛlɛma ani ka yɛlɛma ka kɛɲɛ ni minanw ye. Ni an be yɔrɔ gwɛlɛw ka hakɛ yɛlɛma ka kɛ yɔrɔ nɔgɔmanw ye (a ka ca a la, 30:70 ka taga se 50:50 ma), fɛɛn dɔ ka gɛlɛya (30-95S. Gɛlɛya hakɛ min be yen), fanga (min be se ka kɛ 60 MPa ye), ani a be se ka yɛlɛma yɔrɔ min na (400 ka ca ni 400 ye) be se ka kɛ sababu ye. Ɲɛyirali fɛ, yɔrɔ min ka gwɛlɛ kosɔbɛ, o be se ka kɛ sababu ye ka farikoloɲanagwɛ latanga min ka ɲi ka datugu, k’a sɔrɔ yɔrɔ min ka ɲi ka yɛlɛma, o be kɛ fani minw be se ka yɛlɛma.

Ka fara o kan, yɔrɔ nɔgɔmanw ka sugandili be nɔɔ to lamini yɛlɛmani kan. TPU, k’a sababu kɛ a ka bonw ka jigi ye, a ka ɲi ka kɛ yɔrɔ sumaninw na (i n’a fɔ jikuruw yɛlɛmayɔrɔw). Poliyesitɛri TPU, k’a sababu kɛ a ka mekaniki fanga ye, a ka ca a la, a be baara kɛ ni baarakɛfaniw ye minw be se ka yɛlɛma yɛlɛma.

II. Waleya sira minw be kɛ ka baara kɛ ni fɛɛn caaman ye .

TPU faniw ka baarakɛcogo tɛ fɛn kelen hakɛ ye, nka a be se ka kɛ ɲɔgɔndan ye min be sɔrɔ multi{0}}dimensiyɔn dilan cogo fɛ.

Ka Elastiki ni lafiya sabati .

Elasticity ye TPU faniw nafa jɔnjɔn ye, ani a labɛncogo be basigi ka molekiliw ka lafiya kɛcogo kɔlɔsi. Ni an ye -molecule -} girinya yɛlɛmalan (i n’a fɔ butanɛdili), yɔrɔ gɛlɛnw cɛ, o be surunya, o be dɔ fara farikolo ɲɔgɔndan hakɛ kan yɔrɔw ni ɲɔgɔn cɛ ani o cogo la, a be yɛlɛmani don elastisite la. Ka fara o kan, nɛgɛ min be kɛ ni yɔrɔ fila ye wala min be se ka yɛlɛma, o b’a to mɔgɔw be se ka yɛlɛma cogo kelen na, o min be se ka kɛ ka fani minw be se ka yɛlɛma, u be se ka yɛlɛma yɔrɔ minw na.

Jii be se ka don ani a be se ka fiɲɛ bɔ .

Waterproof and breathable TPU membranes (such as the biomimetic structure of Gore-Tex) are produced using a phase inversion process. By regulating the solvent evaporation rate, micropores with diameters of 0.1-5 μm (approximately 700 times the size of a water vapor molecule, but smaller than the size of a liquid water droplet) are formed. This design utilizes the hydrophobicity of TPU (contact angle >100 degere ) ka kɛnɛma jimanya bali k’a sɔrɔ a be se ka kɛ ko nɔgɔ be jɛnsɛn mikroporow fɛ. Dɔw be 10/{3}} TPU yɔrɔ dɔ don tugun, min tɛ-porozi ye, min be jimanfɛnw lataga yɔrɔ minw na (i n’a fɔ ure) molekiliw ka cakɛda la, ka ninakili sɔrɔ ni porozite tɛ.

A be yiriwa ani k’a to a be se ka kɛ .

Ka se ka yɔrɔ juguw kunbɛn, UV absorers (i n’a fɔ benzotriazɔliw) ani antioksidan (i n’a fɔ fenoli minw be bali) ka teli ka fara TPU ka furakisɛw kan walisa ka polimɛri jɔlɔkɔ ka fotookisiditi dɔgɔya. Ka ɲɛsin kemikalifɛnw ma (i n’a fɔ furakɛli banakisɛ walima ka fɛnw yɛlɛma izini kɔnɔ), molekiliw ka basigili be sabati ni yɔrɔ gɛlɛnw ka kristalinite ye (i n’a fɔ, ka baara kɛ ni disocianati aromatiki ye), o min b’a to a be se ka yɛlɛma ni asidi ni alkali ye ni pH 2-12 ye.

III. Tagamacogo fɛɛrɛ be dɛmɛ don ka laɲinitaw labɛn .

TPU faniw ka baarakɛcogo be laban ka bɔ baara tigitigi lo la. Hot-melt lamint fɛɛrɛ (i n’a fɔ TPU filimu ani fani ɲɔgɔndanw) b’a to mɔgɔw be ɲɔgɔn minɛ ni 3 N/cm ye wala u be bɛn ɲɔgɔn ma ni funteni kɔlɔsili ye (120{{5}180 degere ) ani degun (0,3-0,5 MPa) k’a sɔrɔ u be yɔrɔ minw be yɛlɛma yɛlɛma, u tɛ se ka yɛlɛma. Fɛɛrɛ min be se ka kɛ, o be bɛn yɔrɔ kuruninw ma (i n’a fɔ glove liners). O fani gɛrɛntɛ (50-200 μm) ani ka kelenya be se ka yɛlɛma n’an be furakisɛ sugandi (i n’a fɔ DMF wala THF). Saan tɛmɛninw na, 3D sɛbɛri fɛɛrɛ donni y’a to TPU sera k’a ka yɔrɔw labɛn ka kɛɲɛ ni ergonomi kunnafoniw ye, misali la, ka fɛnw yɛlɛma yɛlɛma ani ka dɛmɛ don ka ɲɛ yɔrɔw la.

IV. O la, a be se ka kɛ ko a be se ka sabati

Bi TPU ka fani dilan cogo be to ka lamini teriw bila ɲɛfɛ. Bio- min basiginin be TPU kan, o be baara kɛ ni yiri - ye min basiginin be poliyɔliw kan (i n’a fɔ mugu tulu) sanni ka kɛ petɔrɔli- ye min basiginin be fɛnɲɛnamafagalanw kan walisa k’a ka karibɔni sennɔ dɔgɔya. O la, a be se ka kɛ ko TPU ka thermoplastisite be se ka yɛlɛma, o min b’a to a be se ka kɛ cogo caaman na funteni yɛlɛmani fɛ (ni yɛlɛmani hakɛ be tɛmɛ 90 kan. Sɛgɛsɛgɛli dɔw fana ye TPU fototalan sɛgɛsɛgɛ, k’a ka toli hakɛ teliya lamini na, ka karibɔniyli baarakɛcogo kuluw don a la.

Kuma laban

TPU ka faniw dilan cogo ye kariti tigitigi ye min be minanw ka mikrostructure ani makroskopi kɛcogow yira. K’a ta molekiliw labɛncogo labɛnni na ka taga a bila makroskopi baara la, fɛɛrɛ kelen kelen bɛɛ be bɛn ni baarakɛcogo kɛrɛnkɛrɛnninw ye. Ni cross-innovation ye polimɛri sɛgɛsɛgɛli fɛɛrɛ ni fani dilan cogo la, TPU faniw be yiriwara ka taga baaraba la, baarakɛcogo ka bon, ani ka to ka sabati, ka to ka yɛlɛmaniw don yɔrɔ dɔw la i n’a fɔ fani ɲumanw ani furakɛli latanga minanw.
