Abstract

Le but de la présente invention est de fournir un procédé de production d'un coagulum caractérisé en ce qu'il est obtenu par coagulation d'une composition aqueuse de résine d'uréthane à l'aide d'une solution aqueuse d'un agent coagulant non métallique, laquelle est chauffée à 40 °C ou plus. La présente invention traite le problème consistant à fournir un procédé de production qui permette d'obtenir un coagulum ayant une excellente texture sans utiliser de solvant organique. Le procédé de production selon la présente invention est capable de produire un coagulum d'une excellente texture. De plus, ledit procédé de production n'utilise pas de solvant organique dans un bain de coagulation, ce qui lui évite de poser un risque d'exposition à des substances volatiles nocives ou de diffusion de celles-ci dans l'environnement, et il permet à un liquide résiduaire du bain de coagulation d'être traité par un procédé simplifié, ce qui peut contribuer à réduire les coûts de production. En outre, étant donné que ce procédé de production n'utilise aucun agent coagulant qui contient du métal, il n'induit donc pas de rouille ni de détérioration de l'appareil de production utilisé pour produire le coagulum. Ainsi, le coagulum obtenu par le procédé de production selon la présente invention peut être utilisé de manière appropriée pour la production de gants, de matériaux de revêtement, de feuilles de type cuir, etc.
