    • The invention provides a novel method for making paper of regenerated chious fibers without the use of any binder materials. By virtue of the inherent physiological inertness of the chitinous fibers and the absence of any binder materials, the paper obtained by the inventive method is advantageously used in medical treatment in contact with living body tissues. The principle of the method is that the chitinous fibers prepared by a wet spinning process are never brought into a dry condition or always kept wet with water down to the step of sheet making so that the self-bonding power of the fibers by the hydrogen bonding is never decreased and a chitinous paper with sufficient strengths can be prepared without a binder material. Alternatively, once dried chitinous fibers can be treated with a hydrogen-bond forming agent, e.g. urea, so that the sheet making is equally successful without the use of a binder material.
    • 本发明提供了不使用任何粘合剂材料制造再生几丁质纤维纸的新方法。 由于几丁质纤维的固有生理惰性和不存在任何粘合剂材料,通过本发明方法获得的纸有利地用于与生物体组织接触的医疗中。 该方法的原理是通过湿纺丝方法制备的壳多糖纤维不会进入干燥状态,或者始终保持用水润湿直至制片步骤,使得通过氢键的纤维的自粘合力 不会减少,并且可以在没有粘合剂材料的情况下制备具有足够强度的几丁质纸。 或者,一旦干燥的几丁质纤维可以用氢键形成剂,例如, 尿素,使得片材制造同样成功,而不使用粘合剂材料。
