    摘要: The present invention relates to wadding in which short fibers (A) having a single fiber fineness (a) of 0.001-1.0 dtex make up 5-90 mass % of the total mass of the wadding. Measured in accordance with JIS L 1096 Warmth Retention Method A (Constant-Temperature Method):2010, a 89% or higher warmth retention ratio is obtained in test items made by stuffing 100 g of the wadding substantially evenly into a pouch-shaped cover produced by layering two pieces of 45 cm-length 100% cotton fabric squares and thereafter sewing shut the opening of the pouch-shaped cover. By means of the present invention, it is possible to provide wadding which has excellent softness and bulkiness and which is ideal for use in down jackets, duvets or other bedding.

    摘要: The present invention relates to a method for producing a vinylamine unit-containing polymer, the method comprising: preparing a mixture for polymerization (a) containing N-vinylformamide as a monomer component by using crude N-vinylformamide which contains the N-vinylformamide and formamide and has a content of the formamide of 1 part by mass or more with respect to 100 parts by mass of the N-vinylformamide; obtaining a polymerization product (b) containing an N-vinylformamide unit-containing polymer and formamide by polymerizing the monomer component in the mixture for polymerization (a); and obtaining a hydrolysis product (c) containing a vinylamine unit-containing polymer through a hydrolysis treatment of the polymerization product (b) using an acid or a base.
