Process for the production of a multilayer fabric comprising the steps of: (a) feeding at least a first fabric (101) and a second fabric (102) to a constraining device (15), wherein the first fabric (101) is a non-woven fabric, comprising a plurality of filaments adapted to be crimped, preferably bicomponent filaments; (b) constraining said first and said second fabric (102) to each other, so that to define a plurality of constraining points or zones (P) between said first fabric (101) and said second fabric, and so that said first and second fabric (102) are superimposed; (c) heating said first and second fabric (102), so that the filaments of the first fabric (101) develop a crimp, thus increasing the thickness of the first fabric (101) and shrinking the length and the width of the first fabric (101), the shrinking of the first fabric (101) being greater than the shrinking of the second fabric (102).

A mask made of knitted fabric includes a knitted cloth and two ear loops. The two ear loops are knitted together with the knitted cloth and are respectively located on two sides of the knitted cloth. The knitted cloth is composed of a double-layer knitted structure and a single-layer knitted structure. The double-layer knitted structure is a basis of the knitted cloth. The single-layer knitted structure defines at least one bending line, the single-layer knitted structure is only connected to one of two surface layer textures to which the double-layer knitted structure belongs, and whether the bending line is a valley fold line or a mountain fold line is determined by connection between the single-layer knitted structure and the double-layer knitted structure.

An upper-torso garment includes a tubular-jacquard knit structure within a chest-covering portion. The tubular-jacquard knit structure includes interlocked courses formed by each front-stitch course intermittently interlocking with a back-stitch course. The tubular-jacquard knit structure is divided into a plurality of zones across the chest-covering portion, and the zones may include different versions of the tubular-jacquard knit structure based on how front-stitch courses interlock with back-stitch courses.

Three-dimensionally knitted noble metal gauzes, or sections of such gauzes, for carrying out catalytic reactions of fluids are knitted in two or multiple layers and the meshes of the individual layers are connected to one another in one form by a pile thread or multiple pile threads, so that the noble metal gauze has a tertiary structure.

An upper-torso garment includes a tubular-jacquard knit structure within a chest-covering portion. The tubular-jacquard knit structure includes interlocked courses formed by each front-stitch course intermittently interlocking with a back-stitch course. The tubular-jacquard knit structure is divided into a plurality of zones across the chest-covering portion that may vary based on how front-stitch courses interlock with back-stitch courses.

An upper-torso garment includes a tubular-jacquard knit zone with a plurality of front-stitch courses and a plurality of back-stitch courses, where each front stitch course intermittently interlocks with a back-stitch course to form a plurality of interlocked courses. Interlocking cross overs within a first interlocked course are offset from interlocking cross overs within an adjacent second interlocked course.

Provided is a spunbound nonwoven fabric for use in filters which has excellent rigidty, folding endurance, and uniformity of a weight a unit area, and which also has dust collection perforance and mechanical properties. The spunbond nonwoven fabric for use in filters includes a thermoplastic continuous filament and has a partially fused portion. The nonwoven fabric has a stiffness of 2 mN or more and 100 mN or less, a weight per unit area-CV value 5% or less, and a weight per unit area of 150 g/m.sup.2 more and 300 g/m.sup.2 or less.

A vehicle seat includes a first knitted fabric layer defining an outer surface and a second knitted fabric layer defining an inner surface. The inner surface is opposite the outer surface. The vehicle seat further includes a knitted spacer fabric interconnecting the first knitted fabric layer and the second knitted fabric layer. The knitted spacer fabric resiliently biases the first knitted fabric layer and the second knitted fabric layer away from one another. The knitted spacer fabric is configured to buckle when a seated occupant exerts an occupant load on the vehicle seat. The first knitted fabric layer is more elastic than the second knitted fabric layer to conform to the seated occupant when the seated occupant exerts the occupant load on the vehicle seat.
