将手套胚套在手模上，烘烤，使手套胚温度达到90℃-100℃，然后浸入到步骤2中的胶乳中，缓慢平稳提出，在空气中晾置3分钟；(其中手模温度的高低影响制品的厚度)
4、压纹
将步骤3得到的手套的掌面放到带有花纹的钢板上，背面通过有3公斤压力的压力装置压制10秒；
5、烘干
将步骤4得到的手套放入烘干箱内，进行第一次烘干，温度75℃—85℃、时间10分钟；
6、水洗
将步骤5烘干后的手套进入泡水池中进行水洗35分钟，其中泡水池分为三道水池，每道水池的温度分别为50℃—55℃,55℃—60℃,60℃—65℃。
7、再烘干
将步骤6水洗后的手套，然后进行第二次烘干；第一段温度80℃—90℃，时间20分钟；第二段温度90℃—100℃，时间20分钟；第三段温度100℃—110℃，时间15分钟，得到天然乳胶热敏机械压纹防滑手套产品。
此种天然乳胶热敏机械压纹手套的制备工艺所制备的产品，技术指标如下：
附着力(剥离强度)：40N；
厚度：胶面厚度2mm；
撕裂强度：达到并超过四级(≥75N)；
耐磨损力：≥2000周期，达到三级水平。
本发明采用以上技术方案，与现有技术相比具有以下优点：
采用本发明工艺生产出的手套，手掌内部浸胶后进行机械起纹，更好的提高了抓着力和保护力；涂层能防止液体的进入，制得的手套质地柔软、轻巧灵敏、透气性好，长时间穿着不易疲劳，特别适合应用于机械行业操作。而同时也在环保的基础上避免了用锌铵络合物作为热敏剂时，其中的氧化锌对产品的后期老化性能的影响以及产品喷霜的影响。
