This invention provides a novel swab-shaped solubilized collagen fiber which is crimp and without fiber-opening failure (fiber bundle adhesion), which has water content and hydrophilic organic solvent content uniformly distributed therein, and is capable of being uniformly solved in water instantly when used.According to the swab-shaped solubilized collagen fiber, a swab obtained by forming into a spherical shape a bundle of uniform solubilized collagen fiber, which is consisted of a composition containing a solubilized collagen of 66~87% by weight, a buffer salt of 2~6% by weight, water content of 10~22% by weight, and residual hydrophilic organic solvent present in an amount of tracer level to 6% by weight (the above components are 100% by weight in total), which has a diameter of 3~25mm, a weight of 3~20mg, an average fineness of 3~10dtex, and a length of 1~20cm and is formed with a wave-like shape, has a bulk density of 4.0~8.0mg/cm3, and a diameter of 3~25mm, wherein the solubilized collagen fibers are distributed within the swab with the respective solubilized collagen fiber intersecting with one another in one part thereof and separating from one another in the other part thereof.本發明提供一種新穎的綿球可溶化膠原纖維,其係有捲縮且沒有分纖不良現象(纖維束會固著),水分量及親水性有機溶媒量是均勻分佈的狀態,使用時會瞬間均勻地溶解。該綿球可溶化膠原纖維是:由可溶化膠原66至87重量%、緩衝鹽量2至6重量%、水分10至22重量%、及殘留親水性有機溶媒存在量為痕跡量至6重量%(以上合計100重量%)所成之組成物所構成、直徑3至25mm、重量3至20mg、平均纖度3至10dtex、長度1至20cm、由具有有波浪的形狀之均勻狀態的可溶化膠原纖維的纖維束形成為球狀的綿球是,容積密度4.0至8.0mg/cm3、綿球的直徑3至25mm,且在綿球內部,各可溶化膠原纖維係以一部分纏繞、其他的部分為分開的狀態分佈。3‧‧‧第1溶媒槽5‧‧‧活塞槽7‧‧‧噴嘴9‧‧‧齒輪幫浦11‧‧‧捲繞滾筒13‧‧‧第2溶媒槽A‧‧‧可溶化膠原水溶液F‧‧‧可溶化膠原纖維S1‧‧‧有機溶媒S2‧‧‧親水性有機溶媒
