摘要:
A composite material formed by combining a polyurethane material with an unclickable foam layer and a scrim layer through roll and flat form technology. The composite material is embossed to form pillowlike chambers or cells delineated by a network of emboss pattern lines formed by the bonding between these layers.

The invention is a method for making a product (1) comprising a laminar support (9) and a finishing layer (F). This method comprises the following operations: applying on a supporting surface (2) at least one layer of a first substance (4); applying on a surface (8) of the laminar support (9) at least one layer (10) of a second substance (11); treating the layer (10) of the second substance (11) in such a way that the second substance (11) has an absolute moisture value included between 12% and 25%; coupling the supporting surface (2) with the laminar support (9) in such a way as to place the first substance (4) in contact with the second substance (11); applying a pressure (P) on the supporting surface (2) and/or the laminar support (9) in such a way as to press the first substance (4) against the second substance (11); consolidating the union of the first substance (4) and of the second substance (11); removing the supporting surface (2) from the layer of the first substance (4). The invention also concerns a system (100; 200; 300) for making a product (1) comprising a laminar support (9) and a finishing layer (F), and a product (1) comprising a laminar support (9) and a finishing layer (F).
摘要:
Disclosed herein are externally stabilized, poromeric, synthetic leathers having improved embossing characteristics that are made from a fabric that is optionally impregnated with a polymer resin, wherein the fabric is coated with a polymerized layer that was made from a frothed mixture comprising polyurethane dispersed in water (PUD), at least one surfactant, a thickener, and at least one polyolefin dispersed in water (POD). Methods of making said synthetic leathers are also disclosed.

The present invention relates to a process for preparing a printed synthetic suede leather, a printed synthetic suede leather obtainable by said process and the use of said synthetic suede leather as a cover in automotive and furniture applications or as outer garments. The process comprises the steps of (a) foaming a composition comprising an aqueous polyurethane dispersion; (b) applying the foamed composition to a printed textile substrate composed of a yarn; (c) coagulating the polyurethane dispersion; (d) drying; and (e) condensation.

The invention relates to a method for plasticizing one or both surfaces of a nonwoven with polyethylene or polypropylene melted at a temperature of 400 DEG C and stuck by cooling at a temperature of -4 DEG C by means of contact with the pressure cylinders (Fig. 1) at a low temperature (-4 DEG C). The displacement speed of the fabric is 15 m/min and the force of impregnation is 210 kg. force/cm . The resulting nonwoven, whose fiber composition consists of polyester-rayon mixtures (ideally 50 %- 50 %), is a light fabric which is resistant to traction and tearing forces and totally impervious to water, blood, vapor and air and has a surface that absorbs liquids and moderately viscous substances, thereby making it suitable for the manufacture of disposable garments. The garments, which can be previously sterilized, can be bibs for children or adults undergoing dental treatment, bed sheets that are used during childbirth or surgery and gowns, trousers, shirts, camisoles, skirts and garments for medical staff. Aprons for housewives can also be manufactured.

摘要:
A process of treating a resin-impregnated microfibrous non- woven matrix, characterized in that it includes the following treatment steps: - providing a microfibrous non- woven matrix having a top surface to be treated; - preparing said top surface of said matrix by hot calendering and/or buffing; - grouting said matrix by depositing and distributing a base resin coat thereon; - performing a micro-droplet spray deposition of one or more resins, a hot drying step being carried out on said matrix between the deposition of one layer and the deposition of the next layer, preferably an oven-drying step at a temperature ranging from 80°C to 150°C, more preferably at a temperature ranging from 90°C to 110°C; - hot embossing the surface of said matrix, said embossing step being carried out by partial melting of the fibers of said matrix, to cause a permanent deformation in said fibers of said matrix; - performing a micro-droplet spray deposition to form one or more continuous protective layers of one or more resins.
