解析
本题考查倍数表达法的知识点。解题思路是要熟悉常见的倍数表达结构，然后根据题目所给的句子结构和选项来判断正确答案。
倍数表达法常见的结构有：“倍数 + as + 形容词/副词原级 + as” ，用于表示“是……的几倍”。
在本题中，“cotton”是可数名词，要用“many”来修饰。根据“倍数 + as + 形容词/副词原级 + as”的结构，“twice”是倍数，“many”是形容词原级，所以正确的表达应该是“twice as many... as”。
选项B “as twice many” 结构错误，不符合倍数表达法的正确结构；选项C “twice many as” 缺少了第二个“as”，结构不完整；选项D “as many twice” 同样不符合倍数表达法的结构。
