合成了两种封闭异氰酸酯预聚物BIP-S和BIP-H，并利用多种技术研究了bip的三维图案整理性能。结果表明，BIP-H比BIP-S具有更高的玻璃化转变温度、抗拉强度和抗拉模量。两种抗氧化剂的结合产生了良好的性能，可以防止高温和阳光照射下变黄。涂覆BIP-S的3D图案整理棉织物的透明度高于未涂覆的棉织物。涂有BIP-S的棉织物和涂有BIP-H的棉织物对碱溶液的防水性都很好。
Two kinds of blocked isocyanate prepolymers (BIPs), BIP-S and BIP-H, were synthesized, and three dimensional pattern (3D) finishing properties of BIPs were investigated with several techniques. As a result, the BIP-H exhibited higher glass transition temperature, tensile strength, and tensile modulus than did BIP-S. The combination of two kinds of antioxidants resulted in good performance that prevented yellowing at high temperature and exposure to sunlight. 3D pattern finished cotton fabrics coated with BIP-S showed a higher transparency than that of non-coated cotton fabrics. Both cotton fabrics coated with BIP-S and those coated with BIP-H showed excellent repellency to alkali solution.
