ZB B45009-1988 羊毛净毛率测定方法.pdf

1、ZB B 4500988 1 适用范围 本标准适用于养羊业中个体或群体的羊毛净毛率的测定,也可供羊毛流通过程中净毛率测定的参考。 2 采样方法 2.1 个体净毛率样本的采集 在羊的左侧体侧部采下10cm10cm范围生长一年的毛样,不得抖掉沙土杂质,同时记录其重量。 2.2 群体净毛率样本 2.2.1 毛包采样。剪毛后羊毛在打包时,按每三个毛包在一个毛包中采样。具体采样步骤如下：在毛包的上下四个角及毛包中央共九个部位, 随机抽取羊毛共800900g。均匀混合后等分为四份,掉下的沙土杂质也分为四等份, 分别装入塑料毛样袋中。现场进行称重、记录,并标记出基本样,对照样及后备样一与二, 共四个样本。

2、2.2.2 钻孔取样。用直径25mm钻孔采样器,按羊毛打包时压缩垂直方向钻孔,每包钻一孔(或每三包取一包,在该包两侧各钻1或2孔,共三孔)。钻孔器取出后要立即装袋并扎紧,待钻孔器采样够一样本重量(150200g)时,立即称重记录。 2.3 毛样标记 所采毛样(个体或群体)必需注明产地、场名、羊的类别、等级、毛包号、重量(准确度为0.01g)采集日期、采集人。 3 净毛率测定程序 3.1 毛样重量以现场称重为准。 3.2 松毛和抖土。使用开毛机或用手撕松毛样,抖去沙土和除去草屑。注意不丢失毛纤维。 3.3 选用碱性或中性洗毛液,并按下列程序洗毛。 3.3.1 碱性洗毛液 3.3.2 中性洗毛液

4、为23min,正反各30转。 3.5 用烘干法测定净毛率 3.5.1 烘毛 毛样在八篮烘箱中,温度为100105进行烘干,2h后第一次称重,40min后进行第二次称重,两次称重误差不超过0.01g,即可作为该毛样的绝干重。误差超过0.01g时,每隔20min重复称一次,直至两次重量不超过0.01g为止，即为其绝望干重。 3.5.2 净毛率的计算 净毛率()洗净毛绝干重(1标准回潮率)原毛毛样重100 注：标准回潮率暂按：细羊毛17,半细羊毛16,异质毛15。 3.6 用快速净毛率测定仪(挤干法)测定净毛率 3.6.1 将规定重量的毛样(同质细毛200g,同质半细毛及异质毛150g)按本标准2.

5、2至2.4。进行洗毛,将洗净后的毛样放入68-A型净毛率测定仪的压毛筒内,关好挡盖,加压至180kgcm2的状态下,维持稳定1min,压去水分,然后减压，卸下毛筒取出毛样,进行称重。准确度要求0.01g。根据所称重量, 按同质毛及异质毛分别查表1、表2,得出相应的净毛率。 4 测试报告 测试报告应表示出分析日期毛样的产地、场名、羊的类别、等级,毛包号(或个体羊号)、洗毛采用碱性或中性洗液及测定仪器的型号。 表 1 国产同质毛湿压重与净毛率查对表 （68-A型净毛率测定仪适用） 水槽号 LS净洗剂， 元明粉，洗液剂量,L 洗涤时间,min 温度， 1 2 3 4 5 0 0.1 0.05 0 0
