Study on recovering wool fibers from sheepskin scraps by enzymatic method
In order to establish an enzymatic cleaning process for recovering wool fibers from sheepskin scraps,orthogonal test and comprehensive index calculation method are used to optimize the addition amount of compound enzyme preparation and enzymatic hydrolysis process.The differences of scale structure and physical properties between enzymatic recovered wool fibers and natural wool fibers are analyzed.The results show that under the condition of 35℃,by adding a compound enzyme preparation of 0.5 g/100mL alkaline protease,1 g/100mL amylase,and 0.1 g/100mL lipase,respectively,and adjusting the pH value of the bath solution to 9.0.After 5 hours later,the wool fibers could be separated from the sheepskin scraps and recycled to obtain the wool fibers that could be used for textile.
