Title
(EN) METHOD FOR MANUFACTURING GLOVES
(FR) MÉTHODE DE FABRICATION DE GANTS
(JA) 手袋の製造方法
Abstract
(EN)
Provided is a method for manufacturing gloves, comprising: a step for forming a dip-molded layer by dip-molding a latex composition containing a latex of a carboxyl-group-containing conjugated diene rubber (A), a metal compound (B) including an at least divalent metal, and a hindered-phenol-based aging inhibitor (C); and a step for irradiating the dip-molded layer with radiation; wherein the content of the hindered-phenol-based aging inhibitor (C) included in the gloves after irradiation thereof with radiation is 5,000 wt ppm to 70,000 wt ppm.
(FR)
L'invention concerne une méthode de fabrication de gants, comprenant : une étape de formation d'une couche moulée par immersion par moulage par immersion d'une composition de latex contenant un latex d'un caoutchouc diénique conjugué contenant un groupe carboxyle (A), un composé métallique (B) comprenant un métal au moins divalent, et un inhibiteur de vieillissement à base de phénol encombré (C) ; et une étape d'irradiation de la couche moulée par immersion avec un rayonnement ; la teneur de l'inhibiteur de vieillissement à base de phénol encombré (C) inclus dans les gants après leur irradiation avec un rayonnement étant de 5 000 ppm en poids à 70 000 ppm en poids.
(JA)
カルボキシル基含有共役ジエン系ゴム(A)のラテックスと、2価以上の金属を含む金属化合物(B)と、ヒンダードフェノール系老化防止剤(C)とを含有するラテックス組成物をディップ成形することで、ディップ成形層を形成する工程と、前記ディップ成形層に、放射線を照射する工程と、を備える手袋の製造方法であって、放射線照射後の手袋中に含まれる、前記ヒンダードフェノール系老化防止剤(C)の含有量を5,000重量ppm以上、70,000重量ppm以下とする手袋の製造方法が提供される。
