Abstract
Official abstract text for this publication.
A method of producing a laminated body, the method including a coagulant solution deposition step of depositing a coagulant solution on a fiber substrate, and a coagulation step of forming a polymer layer on the fiber substrate by bringing a polymer latex into contact with the fiber substrate having the coagulant solution deposited thereon to cause a polymer to coagulate. As the coagulant solution, a solution obtained by dissolving or dispersing 0.2 to 7.0% by weight of a metal salt as a coagulant and 0.1 to 7.0% by weight of an organic acid in a solvent is used. In the method of producing a laminated body, the metal salt is a polyvalent metal salt. In the method of producing a laminated body, the organic acid is an organic acid having at least one group selected from a carboxyl group, a sulfo group, a hydroxy group, and a thiol group.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of producing a laminated body, the method comprising: a coagulant solution deposition step of depositing a coagulant solution on a fiber substrate; and a coagulation step of forming a polymer layer on the fiber substrate by bringing a polymer latex into contact with the fiber substrate having the coagulant solution deposited thereon to cause a polymer to coagulate, wherein as the coagulant solution, a solution obtained by dissolving or dispersing 0.2 to 1.0% by weight of a metal salt as a coagulant and 0.1 to 3.0% by weight of an organic acid in a solvent is used, and the metal salt is calcium nitrate and the organic acid is acetic acid. 2. The method of producing a laminated body according to claim 1 , wherein a polymer constituting the polymer latex is a nitrile rubber. 3. The method of producing a laminated body according to claim 1 , wherein in the coagulation step, the polymer layer is formed so that a permeated polymer layer, which, of the polymer layer, is a portion having permeated into the fiber substrate, has a thickness of 0.05 to 0.6 mm. 4. The method of producing a laminated body according to claim 1 , wherein in the coagulation step, the polymer layer is formed so that a top surface polymer layer, which, of the polymer layer, is a portion having not permeated into the fiber substrate, has a thickness of 0.05 to 0.6 mm. 5. A method of producing a protective glove using a laminated body obtained by the method of producing a laminated body according to claim 1 .
