Bloques de fibra mineral y su producción |
摘要 |
A dual density mineral fibre batt is made by splitting a web (1) into upper and lower sub-webs (5 and 6) and then subjecting both sub-webs independently to treatments selected from lengthwise compression, lengthwise stretching and thickness compression and then re-joining the sub-webs. The lower layer of a novel dual density batt has Tau and Kappa values (determined by Fourier Transformation of scanned images of thickness cross sections X and Y in the lengthwise production direction and transverse to this) in which KX is usually greater than Ky and greater than 2.5 and TX is usually greater than Ty. |
