また、太陽光遮蔽物質の平均粒子径が0.5μmより大きいと、製糸性が低下するとともに、赤外線の波長を効率的に反射することができず、十分な遮熱効果を得ることができない。太陽光遮蔽物質の平均粒子径は好ましくは0.4μm以下、より好ましくは0.3μm以下である。また、太陽光遮蔽物質は、赤外線の波長を反射できる限りその平均粒子径は限定されないが、好ましくは0.05μm以上、より好ましくは0.1μmを超えてもよい。 Furthermore, the present invention efficiently contains an infrared wavelength that is easily converted into thermal energy by containing 8 wt% or more and 70 wt% or less of a sunscreen material having an average particle size of 0.5 μm or less in the A component polymer. Reflects and exhibits a heat shielding effect. When the content of the sunlight shielding substance is less than 8% by weight, the infrared wavelength cannot be efficiently reflected, and a sufficient heat shielding effect cannot be obtained. On the contrary, if the content of the sunlight shielding substance exceeds 70% by weight, the spinnability at the time of spinning is extremely deteriorated, and the coloring property at the time of dyeing is lowered. Preferably it is 10 weight% or more, More preferably, you may exceed 20 weight%. On the other hand, from the viewpoint of improving spinnability, the content of the sunlight shielding substance may be preferably 60% by weight or less, and more preferably 50% by weight or less.
On the other hand, if the average particle size of the solar light shielding material is larger than 0.5 μm, the spinning property is lowered and the infrared wavelength cannot be reflected efficiently, and a sufficient heat shielding effect cannot be obtained. The average particle size of the sunscreen material is preferably 0.4 μm or less, more preferably 0.3 μm or less. Further, the average particle diameter of the sunlight shielding material is not limited as long as it can reflect the wavelength of infrared rays, but it may be preferably 0.05 μm or more, more preferably more than 0.1 μm.
