1、乳胶手套生产工艺Production process of Latex glove手套分类手套分类 Glove classification 按生产原料分类按生产原料分类 Classification by raw material皮手套皮手套 Leather glove 绵羊皮、山羊皮、鹿皮、猪皮、牛皮等制作。 Made of leather of sheep, goat, deer, pig or cattle.线手套线手套 Cotton gloves也叫棉纱手套，纱线手套或针织手套。PVC手套手套 PE手套手套PVC手套是采用聚氯乙烯，通过特殊工艺制作而成。PVC gloves are

2、made of polyvinyl chloride.PE手套是采用聚乙烯, LDPE, HDPE, LLDPE吹膜压制而成。PE gloves are made of polyethylene, LDPE, HDPE, LLDPE. 手套分类手套分类 Glove classification橡胶手套橡胶手套 Rubber gloves橡胶手套，是用橡胶薄片或薄膜制成的一类手套。Rubber gloves are made of rubber sheet or film.乳胶手套乳胶手套 Latex gloves顾名思义，就是使用天然乳胶加工而成，广泛应用于家庭、工业、农业、医疗、美容等行业，

3、乳胶手套分为光面乳胶手套、麻面乳胶手套、条纹乳胶手套、透明乳胶手套及无粉乳胶手套。按用途分为一次性乳胶手套、家用乳胶手套、工业乳胶手套和医用乳胶手套。约6%的人会对乳胶手套过敏。Latex gloves, made of natural latex, are widely used in house, industry, agriculture, healthcare, beauty industry.Latex gloves include glossy latex gloves, ballast-surfaced latex gloves, striped latex gloves,tra

4、nsparent latex gloves and no powder latex gloves. According to the application, latex gloves could be classified as disposable latex gloves, household latex gloves, industry latex gloves, and surgical latex gloves.Approximately 6% of the people are allergic to latex gloves.手套分类手套分类 Glove classificat

5、ion丁腈手套丁腈手套主要成分是乳胶，但不会引起过敏。弹性好、防酸、抗碱、耐磨损、耐油、不带静电。应用在石油化工、电子等行业，经灭菌可应用于医疗。丁腈手套不仅保持了乳胶手套良好的弹性，同时还兼备了PE和PVC手套的高强度和抗氧化能力。所以还广泛应用于食品行业。Nitrile gloves are mainly made of latex and nitrile. They do not cause allergies. And they have good elasticity, anti-acid, anti-alkali, wear resistance, oil resistance,

6、no static. Nitrile gloves are applied in petrochemical, electronic industries. Also they could be used in medical industry after sterilization. For high strength and good oxidation resistance like PE gloves and PVC gloves, Nitrile gloves are widely applied in food industry.从橡胶到乳胶从橡胶到乳胶 From rubber t
