。(Problems to be Solved by the Invention) Among conventional polyester hard cottons, those made by needling a web of polyester fibers tend to have some of the fibers falling off or scattering, and a binder that attempts to prevent this drawback has been developed. Products that are fused together with fibers also lack softness and are hard to the touch, and both tend to collapse under repeated compression or compression in high-temperature atmospheres, and their cushioning properties deteriorate over time. The disadvantage is that it decreases.
