Embodiment Construction
[0029] Objects, advantages and features of the present invention will be illustrated and explained by the following non-limiting description of preferred embodiments. These embodiments are only typical examples of applying the technical solutions of the present invention, and all technical solutions formed by adopting equivalent replacements or equivalent transformations fall within the protection scope of the present invention.
[0030] The invention discloses a two-step fiber-opening method for polyester-nylon composite superfine fibers, which adopts the two-step method of alkali-weight reduction fiber-opening (chemical process) and then mechanical fiber-opening, which changes the traditional process and generally only uses chemical technology to open fibers. Fibrous habitual thinking.
[0031] Specifically, the method includes the following steps:
[0032] S1, Alkali reduction and fiber opening step: set the specified weight of polyester-nylon composite microfiber cloth on...
