摘要
模拟我国和蒙古国洗净羊绒企业山羊绒洗涤工艺,进行了不同的洗涤水温及作用时间、不同的烘干温度及作用时间对口蹄疫病毒灭活作用的检测。结果表明,水温在64℃以下处理60min不能灭活羊绒中的口蹄疫病毒NM-zg99毒株,65℃处理60min、66℃处理45min、75℃处理10min、80℃处理5min能灭活羊绒中的口蹄疫病毒;高温烘干对羊绒中口蹄疫病毒的灭活与温度和作用时间密切相关,70℃处理约35min、75℃处理约25min能灭活口蹄疫病毒,80～90℃处理20min、95～105℃处理15min、110℃处理10min能使口蹄疫病毒失活。该试验结果为我国制定进口洗净毛、绒检验标准提供了参考数据,并对洗净羊绒企业改进羊毛、绒洗涤工艺具有指导意义。
Imitating washing technology of cashmere in Mongolia and China, the inactivating effect of FMD virus in cashmere was detected under different washing temperatures and treating times as well as different drying temperatures and treating times. Results indicated that the FMD virus NM-zg99 strain in the cashmere could not be inactivated by treating in the washing water at below 64 ℃ for 60 min. However, the virus could be inactivated by treating at 65 ℃ for 60 min, 66 ℃ for 45 min, 75 ℃ for 10 min and 80 ℃ for 5 min. There was a close relation between drying temperature and the treating time for the inactivation of the virus in cashmere. The virus could be inactivated by treating at 70 ℃ for 35 min and 75 ℃ for 25 min, 80~90 ℃ for 20 min, 95~105 ℃ for 15 min and 110 ℃ for 10 min. The result provides technical reference for making test standard for importing cashmere washing in China and also has directive significance for the cashmere washing corporations to improve the washing technology of sheep wool and cashmere.
