Abstract
Abstract A lining fabric comprising a first nonwoven layer composed of microfibers produced by melting-blowing, and at least one second nonwoven layer composed of fibers or filaments and an adhesive layer distributed in spots. The first layer and the second layer being bonded, on the one hand, partially by the entanglement of some of the fibers thereof by the application of fluid jets; on the other hand, completely by the base of the spots of the adhesive layer which keeps the fibers interlaced, thus ensuring the cohesion of the assembly as a whole.

Claim 3
Dependent Claim
19 words
The lining fabric as claimed in claim 1, wherein the second nonwoven layer is composed of carded discontinuous fibers.
Claim 4
Dependent Claim
22 words
The lining fabric as claimed in claim 1, wherein the second nonwoven layer is composed of carded fibers bonded by thermal bonding.
Claim 5
Dependent Claim
19 words
The lining fabric as claimed in claim 1, wherein the second nonwoven layer is composed of needled carded fibers.
Claim 6
Dependent Claim
31 words
The lining fabric as claimed in claim 1, wherein the second layer consists of a nonwoven voile formed from synthetic continuous filaments intermingled without orientation and obtained by the melted process.
Claim 7
Dependent Claim
25 words
The lining fabric as claimed in claim 5, wherein the linear density of the filaments forming the second nonwoven layer is higher than 1.5 Dtex.
Claim 8
Dependent Claim
53 words
The lining fabric as claimed in claim 1, defined in that it comprises a third nonwoven layer consisting of synthetic continuous filaments obtained by the melted process and bonded to one of the other two layers by the entanglement of some of their fibers which is obtained by the application of fluid jets.
Claim 9
Dependent Claim
42 words
The lining fabric as claimed in claim 1, defined in that it comprises a third nonwoven layer bonded to one of the other two layers by the entanglement of some of their fibers which is obtained by the application of fluid jets.
