Ki jan fè enspeksyon te santi?
Feel Enspeksyon se kontwòl kalite pou yon materyèl yo te rele Felt.
Nan endistri mòd tankou bouchon ak sak, te santi se youn nan materyèl yo itilize nan yo. Felt se yon materyèl ki fèt sitou nan lenn mouton ak fib bèt ki gen rapò. Li fòme pa chalè, presyon oswa ajitasyon, ak imidite pou fib yo vin konekte ak konplitché, fè li nesesè pou itilize adhésifs pou kenbe yo ansanm.
Lòt fib, tankou rayon oswa koton, ka enkli nan materyèl santi, but they are used as fillers to reduce the cost of the material. Synthetic fibres are used for synthetic felt.
Like non-woven fabrics, the density, hardness, and thickness of felt can be closely controlled and can be easily shaped, since it has no grain.
Felt has excellent shock and sound absorbency, but poor drape, low tensile strength, and usually will not return to shape when unduly stretched.
Felt inspection
Density of the felt is the key point when selecting felt, because it will loose its recovery oversized, but will have poor abrasion performance. Thickness and fibre catergories effect performance as well. Density is usually measured with the unit of g/cm3.
Felt is classified with wool fineness, density and colour. Sepandan, it is also classified by strength, tensibility and capillarity in the technology.
