Abstract

Official abstract text for this publication.

A method of manufacturing a cushioning material P includes a defibrating step of defibrating a cloth to produce fibers F in dry forming, a mixing step of mixing the fibers F with a bonding agent to produce a mixture, an accumulation step of accumulating the mixture in air to produce a web W, and a first forming step of pressurizing and heating the web W to form the web W.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of manufacturing a cushioning material for an object to be packed, the method comprising: a defibrating step of defibrating, in dry forming, a cloth to produce fibers that have an aspect ratio of 0.9 or less; a mixing step of mixing the fibers with a bonding agent to produce a mixture; an accumulation step of accumulating the mixture in air to produce a web; a first forming step of pressurizing and heating the web to form the cushioning material; and a second forming step of, after the first forming step, forming a concave portion by pressurizing a predetermined portion of the cushioning material such that the concave portion has a shape conforming to a three-dimensional shape of the object to be packed. 2. The method of manufacturing a cushioning material for an object to be packed according to claim 1 , wherein the cloth contains cotton or wool. 3. The method of manufacturing a cushioning material for an object to be packed according to claim 1 , wherein in the second forming step, the concave portion is formed by the pressurizing using a mold. 4. A method of manufacturing a packed object, the method comprising: the method of manufacturing the cushioning material for the object to be packed according to claim 1 ; and packing, in the concave portion, the object to be packed to manufacture the packed object. 5. A method of manufacturing a cushioning material for an object to be packed, the method comprising: a defibrating step of defibrating, in dry forming, a knit fabric to produce fibers; a mixing step of mixing the fibers with a bonding agent to produce a mixture; an accumulation step of accumulating the mixture in air to produce a web; a first forming step of pressurizing and heating the web to form the cushioning material; and a second forming step of, after the first forming step, forming a concave portion by pressurizing a predetermined portion of the cushioning material such that the concave portion has a shape conforming to a three-dimensional shape of the object to be packed. 6. The method of manufacturing a cushioning material for an object to be packed according to claim 5 , wherein the knit fabric contains cotton or wool. 7. The method of manufacturing a cushioning material for an object to be packed according to claim 5 , wherein in the second forming step, the concave portion is formed by the pressurizing using a mold. 8. A method of manufacturing a packed object, the method comprising: the method of manufacturing the cushioning material for the object to be packed according to claim 5 ; and packing, in the concave portion, the object to be packed to manufacture the packed object.
