Textile covering of a part, in particular made from plastic

摘要

The textile coating to be applied on an external surface of a plastic material part (2) during the production of the part by casting, useful in automobiles, comprises a barrier unit to make the coating impermeable to the material part during the casting. The textile coating is formed by a textile layer applied on the external surface of the part. The barrier unit is formed by intrinsic elements to the textile and by a textile support covering the interstices of the textile. Number of supports covering the interstices is increased by increasing the displacement of the supports. The textile coating to be applied on an external surface of a plastic material part (2) during the production of the part by casting, useful in automobiles, comprises a barrier unit to make the coating impermeable to the material part during the casting. The textile coating is formed by a textile layer applied on the external surface of the part. The barrier unit is formed by intrinsic elements to the textile and by a textile support covering the interstices of the textile. Number of supports covering the interstices is increased by increasing the displacement of the supports. The supports or meshes are mechanically treated by means of scratching or emerising. The textile comprises bars in which at least a bar near to the surface of the part comprises displacement of the support of interstices obstruction and weak displacement of the support for assuring a good esthetic aspect of coating. The barrier unit is selected from the synthetic multifilament yarn material, which has 20-200 decitex. The filaments are fine to increase the surface of the yarn. The means of barrier used in a gauge machine is >= 28 needle per inches.
