征稿启事

各类大中专学校招生、函授办学、厂矿招工以及公务员考试等．总是要在报名时交备用照片，众多的照片堆放在一起，需要时翻找也是一件麻烦事。我设计了“照片序装袋”，报名对象报名交照片可按报名表的序号插在相应的序装袋中．依次排列好，如有的号欠照片，也易于发现，以便催交，更方便的是在需要谁的照片时就能立即找到；     

Shape memory behavior of SMPU knitted fabric

A preliminary investigation of shape memory (SM) effects of SMPU (shape memory polyurethane) knitting fabric is presented in this paper. Three SMPU knitted fabrics series with different content of SMPU fibers: 100% SMPU, 50% SMPU and 50% cotton, 16% SMPU and 84% cotton are designed and manufactured in our lab. Their shape memory behaviors at different temperatures are characterized in terms of bagging. Our experimental results showed that shape memory effect can be improved with increasing content of SMPU fibers. A comparison between Lycra and SMPU knitted fabrics was also made to validate the shape memory effects of SMPU knitted fabrics.
