In processu ex PVC tarde oxfveld panno significantly afficit eius Air permeability et Breathirability , Praesertim ad applications sicut tentoria, tutela tegit et industriae textilia . Et clavem factors influens haec proprietatibus includit:
I. Base fabricae texentes & density
-
Oxford panno est typically texta est in planus or canistro texere , Varying denier ratings (E.G., 210d, 600D, 1680D).
-
A Superiore texit density Reduces aere permeability, faciens fabricae magis airtight et durabile.
-
A Looser texentes Permittit enim melius airflow sed reduces diuturnitatem et waterproofing perficientur.
II. PVC coating Crassitudo & Composition
-
PVC PVC coatings (E.G .; duplex et triplici-layer) creare omnino non-amet Superficies, faciens fabricae specimen pro Waterproof applications Sed reducendo evacuatione.
-
Tenuior vel microporous coatings Sine aliqui humorem vapor evadere improving breathamability adhuc offerens aqua resistentia.
-
Plasticizer contentus In PVC layer afficit mollitia et permeability Plastestight et Plasticizers facere, ut magis alii alii permittunt permeability.
III. Techniques processus & coating
-
Cultrum coating : Fit Smooth, impermeable Superficies , Signans omnes fabricae poris et ne aer motus.
-
Calendering : De calor et pressura , Faciens PVC layer Denser et minus amet.
-
Laining vs. Direct coating :
-
LAMINATIO (Bonding a pre-fecit PVC film) results in omnino airtight Superficiem.
-
Direct coating (Expandentes Liquid PVC onto fabricae) sino aliquot potestate super poros, sed plerumque reduces aere permeability.
-
IV. Post-curatio processibus
-
Perforatio : Quidam applications requirere Micro-perforationes In PVC iacuit ad amplio aer commutationem dum maintaining aqua resistentia.
-
& Embossing superficiem texit : Quidam vestibulum processus creare parva channels quod leviter augendae humorem administratione, quamquam vera breathability manet limited.
Impact in Applications
-
Titents & Canopies : Omnino Airtight PVC coatings Trap calor et humorem intra, requiring VENTILATIO fenestras aut aer spiracula.
-
Protective Covers : Air impermeability est utile est Waterproofing et pulvis praesidium Sed potest facere condensationem quaestiones, si non evacuatione est praesens.
-
Industrial usu (E.G., Tarps, saccis, upholstery) : Diuturnitatem et Waterproofing præcedenti super Breatheathability, faciens plene iactaret PVC Oxford pannos maluit choice .
