摘　　要：先在KOH作用下,以烯丙基缩水甘油醚和β-环糊精为原料合成带有α烯基的环糊精衍生物——4-(3-烯丙氧-2-羟基)丙氧基-β-环糊精(PCD);然后在铂催化剂的作用下,利用PCD与含氢硅油(PHMS)在二甲基亚砜(DMSO)溶剂中的硅氢化加成反应,合成了一种侧链带有β-环糊精基团的亲水性聚硅氧烷——PDMS-g-β-CD。通过核磁共振氢谱分别对产物的结构进行了表征,对PDMS-g-β-CD进行乳化及复配,并用其对纯棉针织双面布进行整理,测试了样品性能。整理后织物柔软度提高,且随着环糊精侧基含量从0.05%增大至0.14%,弯曲刚度经纬总和从727mN增加至808mN;工作浴液的固含量从0.3%增至1.2%,织物的弯曲刚度经纬总和从808mN下降到748mN;将ASO-1和环糊精侧基聚硅氧烷复配后柔软性提高。Under the action of KOH and by using the Ally glycidyl ether and β-cyclodextrin as raw materials,this paper composes one kind of α-olefine contained cyclodextrin derivative-4-(3-allyloxy-2-hydroxy) propoxy-β-cyclodextrin(PCD),then under the action of the platinum catalyst and through the hydrosilyation additivereaction between 4 -(3 -allyloxy -2 -hydroxy) propoxy -β -cyclodextrin(PCD)and the silicone oil containing hydrogen-PHMS in the DMSO solvent,this paper also synthesizes the hydrophilic polysiloxane with β -cyclodextrin side groups-PDMS-g-β-CD.In addition,this paper characterizes the structure of these synthesized products by using the 1H-NMR,emulsifies the PDMS-g-β-CD,applies it to the pure cotton knitted double cloth and tests the sample's properties.It can be concluded that the softness is improved,and with the content of the β-cyclodextrin side groups increasing from 0.05% to 0.14%,the summed bending rigidity of both warp and weft direction also increase from 727 mN to 808 mN,but with the increase of the solid content in the bath liquid from 0.3% to 1.2%,the summed bending rigidity decreases from 808 mN to 748 mN.Furthermore,it is shown that the mixture of ASO-1 and polysiloxane with β-cyclodextrin side groups can increase the fabric softness.
