Embodiment 1
[0071] The synthetic resin film is manufactured by a normal dry manufacturing method. Specifically, an ester-based polyurethane resin was dissolved in dimethylformamide, and carbon black was blended in an amount of 6% by mass based on the total amount of the polyurethane resin and carbon black to obtain a polyurethane resin composition. The polyurethane resin composition was coated on a release paper, dried at 120° C. to evaporate the solvent, and after the solvent evaporated, it was peeled off from the release paper to prepare a black synthetic resin film made of the polyurethane resin. The thickness of the synthetic resin film was 13 μm.
[0072] Next, titanium oxide was added to the ester-based polyurethane resin adhesive in a ratio of 35% by mass based on the total amount of the polyurethane resin adhesive and titanium oxide, mixed until uniformly dispersed, and a white synthetic resin adhesive was obtained. agent. The obtained synthetic resin adhesive is made into a dry...

Abstract
Provided are a light-shielding and heat-shielding composite sheet and a fiber product which have excellent light-shielding and heat-shielding properties and also have excellent color development properties. This light-shielding and heat-shielding composite sheet is provided with: a fiber fabric; at least one layer of synthetic resin film containing carbon black in a proportion of 4-40 mass%; and a synthetic resin adhesive containing titanium oxide in a proportion of 30-60 mass%, wherein the synthetic resin adhesive bonds the fiber fabric and the synthetic resin film.
Description
technical field [0001] The invention relates to a light-shielding and heat-shielding composite sheet and a fiber product. Background technique [0002] In recent years, with global warming and ozone layer destruction, the increase of heatstroke caused by summer heat, the impact of harmful ultraviolet rays (UV-B) contained in sunlight on the ecosystem and the impact on the human body (skin cancer, immune function damage) drop) has attracted attention as a problem, and in order to solve these problems, there is an increasing demand for improved light-shielding and heat-shielding properties of sunshade materials such as parasols and tents. [0003] Hitherto, high-density woven fiber fabrics dyed black have been used as sunshade fiber products such as parasols, but there is a problem that they cannot sufficiently block ultraviolet rays, visible rays, and infrared rays contained in sunlight. [0004] Therefore, the surface of the umbrella cloth is coated with a resin containing ...
