Flexible sound-insulating hose

摘要

It includes first yarns (2) of plastic material having a diameter of between about 0.5 and 0.7 mm, second braided yarns (3) of bulky material and third yarns (4) having multiple filaments, the ratio between these yarns being any comprised between 1-4-1 and 1-6-3. The invention achieves a great elasticity in the hose and a better sound absorption than in the known insulating hoses.
