This invention relates to a thermally insulating substrate product comprising: a substrate having at least one layer and comprising metallic particles having an average particle size and density selected to block or reflect infrared radiation and aerogel particles having an average pore size and density selected to control conducted and convected thermal energy. The thermally insulating substrate can made as textile and/or film coatings that are light and thin and adapts to external environment conditions for better camouflage as well as improved heat insulation for energy conservation and thermal regulation.

Disclosed is a two layered belt useful in the manufacture of tissue products comprising a first woven layer and a second nonwoven layer joined together in a laminated arrangement. The woven layer typically forms the machine contacting layer of the belt and is woven from a highly abrasion resistant material, while the nonwoven layer contacts the nascent tissue web. The woven layer may be provided with valleys and ridges that the nascent web is molded into, while the nonwoven layer may be provided with elements that impart a visually aesthetic pattern to the web. In this manner the belt may be useful in the production of products having desirable physical properties resulting from molding into the woven fabric while also being visually pleasing to the user.

A breathable and waterproof non-woven fabric is manufactured by a manufacturing method including the following steps. Performing a kneading process on 87 to 91 parts by weight of a polyester, 5 to 7 parts by weight of a water repellent, and 3 to 6 parts by weight of a flow promoter to form a mixture, in which the polyester has a melt index between 350 g/10 min and 1310 g/10 min at a temperature of 270? C., and the mixture has a melt index between 530 g/10 min and 1540 g/10 min at a temperature of 270? C. Performing a melt-blowing process on the mixture, such that the flow promoter is volatilized and a melt-blown fiber is formed, in which the melt-blown fiber has a fiber body and the water repellent disposed on the fiber body with a particle size (D90) between 350 nm and 450 nm.
