Kev ua lag luam kev ua tau zoo- tawm ntawm cov kev kho mob sib txawv

Muaj thiab ua lag luam daim ntawv thov scenarios

Nkag siab txog cov kev kho mob no pab engineers, buyers, thiab designers xaiv qhovtxoj cai nylon cov ntaub ntawv rau ib puag ncig zoo, tsis txhob overengineering lossis ua tsis tiav ntxov.

1. Yog vim li casNylonXav tau dej ntxiv -Kev kho mob

1.1 Kev txwv ntawm Nylon tsis kho

Txawm hais tias nylon fibers tiv thaiv dej nkag mus sai, lawv:

Absorb noo noo sab hauv

Poob qee qhov kev ruaj ntseg thaum ntub

Tso dej kom dhau los ntawm cov qauv woven lossis knitted

Hauv tiag tiag - ntiaj teb daim ntawv thov- nag, ntxhua khaub ncaws, cov av noo siab, lossis lim dej-tsis kho nylon mus txog nws qhov kev txwv sai sai.

1.2 Thaum Yuav Tsum Muaj Kev Tiv Thaiv Dej Zoo

Cov kev kho mob ntxiv ua qhov tseem ceeb thaum siv nylon hauv:

Cov khoom siv sab nraum zoov (tsev pheebsuab, hnab ev khoom, npog)

Industrial lim hnab

Cov khaub ncaws tiv thaiv

Marine thiab automotive Cheebtsam

Kev kho mob thiab tu cev textiles

1.3 Base Nylon vs Kho Nylon

2. Nkag siab txog dej-Cov cuab yeej tiv thaiv

2.1 Nto Zog thiab Wetting cwj pwm

Dej tsis kam yog tswj los ntawm ntaulub zog nto.

Siab saum npoo zog → dej sib kis

Tsawg zog nto → dej hlaws

Kev kho mob ua haujlwm los ntawmtxo lub zog saum npoo, tiv thaiv dej molecules los ntawm kev sib kis los yog nkag mus.

2.2 Sib cuag Angle piav qhia

Ib qho kev ntsuas tseem ceeb rau kev tiv thaiv dej yog qhovcontact lub kaum sab xis.

Feem ntau cov nylon tsis kho muaj lub kaum sab xis hauv qab 90 degree, thaum kho nylon tshaj nws.

3. Cov dej tsis huv (DWR) tiav

3.1 DWR yog dab tsi?

DWR (Durable Water Repellent)yog ib qho tshuaj tiav siv rau cov ntaub nylon uas ua rau dej hlaws thiab dov tawm ntawm qhov chaw.

Cov yam ntxwv tseem ceeb:

Tsis thaiv qhov pores

Ua kom breathability

Siv los ntawm padding, txau, lossis dipping

3.2 Fluorocarbon-Based DWR

Keeb kwm, fluoropolymer -raws li DWRs tau zoo tshaj plaws.

Qhov zoo:

Kev tiv thaiv dej zoo heev

Roj thiab stain kuj

Ntev - kev ua haujlwm ntev

Qhov tsis zoo:

Kev txhawj xeeb txog ib puag ncig

Txoj cai txwv nyob rau hauv ntau lub cheeb tsam

3.3 Fluorine-DWR lwm txoj kev pub dawb

Cov kev xaiv niaj hnub no muaj xws li:

Silicone-raws li tiav

Hydrocarbon-raws li polymers

Wax{0}} hloov kho emulsions

4. Polyurethane (PU) Txheej ntawm Nylon

4.1 PU txheej yog dab tsi?

Polyurethane coatings tsim aua yeeb yaj kiab tsis tu ncuantawm ib sab ntawm cov ntaub nylon, ua kom muaj dej tsis kam.

PU-coated nylon yog siv dav hauv:

Rainwear

Tsev pheebsuab

Kev lag luam npog

Lim cov vaj tsev

4.2 Yuav ua li cas PU txhim kho dej tsis kam

PU coatings:

Seal ntaub pores

Tiv thaiv kom tsis txhob ua kua

Ua kom yooj

4.3 PU-Coated Nylon Performance

PU coatings yog qhov zoo tagnrho qhov twgkev thaiv dej yog qhov tseem ceeb tshaj li kev ua pa.

5. Silicone Coatings: Kev tiv thaiv dej ntau tshaj

5.1 Silicone-Coated Nylon (Silnylon)

Silicone coatings nkag mus thiab encapsulate nylon fibers es tsis tsim ib zaj duab xis nto.

Cov txiaj ntsig tseem ceeb:

Kev tiv thaiv dej siab heev

Zoo heev yooj

Superior UV tsis kam

5.2 Silicone vs PU Txheej

Silicone-coated nylon feem ntau yog siv rau hauvsiab -cov cuab yeej siv sab nraum zoov.

6. Laminated Nylon Fabrics
