Saeko posts on SNS that she loves it Kyowa Sarashi Mensa Pajamas White, size S Gauze pajamas, seriously considering sleep It touches the skin directly. You spend a lot of time together each day. And you wear them every day. I think you can understand its importance just by that. Surprisingly, many people are particular about the clothes they wear daily, but not so much about pajamas. Kyowa Sarashi Mensa's gauze pajamas were made by Daito Bedding Industries, a long-established company founded in 1925 in Fushimi-ku, Kyoto, who thoroughly considered and were particular about "sleep." "Wa-zarashi" that takes 100 times longer "Sarashi" is the process of removing impurities and pigments from woven cotton fabric. Normal bleaching takes about 40 minutes, but in the case of the traditional Japanese method "Wa-zarashi," it takes about 4 days! It takes time and effort, and more than 100 times longer than general bleaching to carefully remove impurities. Currently, many cotton products use processes that compress the fibers or use heat or chlorine-based bleaching agents to finish them in a short time. However, the original roundness of the fibers is lost due to the processes used to finish them quickly. Kyowa Sarashi Mensa's "Wa-zarashi" does not use any chemicals and does not put any stress on the fibers, so the cross-section does not easily collapse, and the original roundness of the yarn creates a fluffy, three-dimensional air layer. By using Wa-zarashi, it becomes soft and gentle with high absorbency and breathability. "Mutenketsu" that drapes air Kyowa Sarashi Mensa's gauze pajamas use "Mutenketsu" gauze fabric that "drapes air" in addition to the "Wa-zarashi method" for a good night's sleep and relaxation. "Mutenketsu" may not be a familiar word, but it is actually a very excellent technique. Normally, when two or three layers of gauze are layered to make a single fabric, "tenketsu" (stitches) are applied to many places, so the structure does not allow air to enter between the gauze layers. On the other hand, Kyowa Sarashi Mensa uses "Mutenketsu," which connects the fabric only at the sewing parts of the edges, to achieve a more comfortable sleep. Since there are no tenketsu between the gauze layers, when you pinch the front and back of the fabric with your hands, it spreads out softly. Sewing with "Mutenketsu" requires time and high skill, but it can create a layer containing a lot of air between the gauze, which greatly increases heat retention and breathability. New, unused item.
