Claims
- 1. In a process for the production of a padding web having a high degree of thermal insulation usable for clothing and furnishing said web having two faces, said process comprising the steps of: providing a web comprising a layer obtained by carding a mixture of fibres of polyester or other fibres with silicone treated fibres of diverse nature and origin;
- resin coating said web,on one face thereof, with a mixture of adhesives having a sticky plastic consistency which, when polymerized, form a soft elastic film;
- spraying onto the opposite face from said one face of said web, a non sticky adhesive;
- calendering the layer thus treated at a set temperature; the improvement of
- applying to at least one face of said web a surface layer of metal particles embedded in a synthetic resin film and
- further calendering said padding web, after drying of said layer of metal particles embedded in said synthetic resin film at a temperature from 100.degree. to 120.degree. C., a pressure from 10 to 30 Kg/cm.sup.2 and a speed of about 30 m/min.
- 2. A process according to claim 1, wherein said synthetic resin film is prepared by the step of:
- treating a film of synthetic resin with an antiadhesive lacquer,
- metallizing said film with a metal layer having a thickness in the range of 12-25 micrometers, and
- transferring said metallized film onto said web by means of said further calendering step.
- 3. A process according to claim 1, wherein said synthetic resin is one of acrylic resin, polyurethane and vinyl resin as a solution in a solvent comprising one of an ester, a ketone, a dimethylformamide and an aromatic hydrocarbon, said solution being composed by the following constituents:
- ______________________________________methyl esters of acrylic acid ppm 60cellulose acetobutyrate ppm 90metal pigment ppm 50toluene ppm 200ethyl acetate ppm 100isobutyl acetate ppm 1000______________________________________
- with a total solid contents of 33% and a viscosity in the range of 5-10,000 cP.
- 4. A process according to claim 1, wherein said solution is composed of the following constituents:
- ______________________________________methyl esters of methacrylic acid ppm 10vinylite VyHH ppm 85cellulose acetobutyrate ppm 5metal pigment ppm 20toluene ppm 50methyl ethyl ketone ppm 150ethyl acetate ppm 20isobutyl acetate ppm 20______________________________________
- with a total solid contents of 33% and a viscosity in the range of 5-10,000 cP.
- 5. A process according to claim 1, wherein said solution is composed of the following constituents:
- ______________________________________polyurethane resin ppm 35dimethylformamide ppm 65metal pigment ppm 50______________________________________
- with a total solid contents of 43% and a viscosity in the range of 8-120,000 cP.
