摘 要:利用成形针织技术制备扁平足矫形鞋垫基体和高分子合成技术制备鞋垫填充用水凝胶,生产制备出了扁平足矫形用鞋垫。探究了弯纱深度对鞋垫透气性的影响,对比分析了改性高岭土使用量对合成聚n-异丙基丙烯酰胺/高岭土复合水凝胶的溶胀、退溶胀、机械性能的影响。研究表明,成圈段和集圈段的针织参数弯纱深度(度目)设置为80、70时,能够得到较好的织物透气性;高岭土浆液中高岭土与去离子水配比为1∶15时,制备出的聚n-异丙基丙烯酰胺/改性高岭土复合水凝胶能够在60 min达到溶胀平衡,在6 min达到退溶胀平衡且断裂强力能达到8 N左右,具有较好的使用性。

Abstract: The body of orthopedic insole for flatfoot was developed by full-fashioned knitting and the insole filling hydrogel was prepared by polymer synthesis technology. The impact of the sinking depth on the air permeability of insole was analyzed, and the effects of the dosage of modified kaolin on the swelling, deswelling, mechanical properties of the synthesized poly (n-isopropylacrylamide)/modified-kaolin hydrogel was analyzed by comparison. The results indicate that a better air permeability could be achieved by setting the sinking depths (stitches) of the looping stitch and tucking stitch were set to 80 and 70 respectively. When the proportioning of kaolin slurry was 1:15 for kaolin and deionized water, the prepared poly (n-isopropylacrylamide)/modified-kaolin hydrogel can achieve swelling equilibrium at 60 min, and de-swelling equilibrium at 6 min, with a breaking strength of up to 8 N and good usability.

Key words: knitted insole; flatfoot orthopedics; hydrogel; n-isopropylacrylamide

扁平足是一种以足弓下降消失为主要特征的足部疾病,表现为运动疼痛和行走姿态的改变,还伴有跟腱炎、筋膜炎、关节炎、骨刺等并发症[1],严重者甚至造成运动功能丧失。足弓垫作为非手术介入治疗扁平足的主要手段,通过抬高足弓部分,分配调整足弓受力,能够使扁平足内的伸长肌腱恢复到正常水平。王瑞霞等[2]、Payehdar等[3]通过长期和即时观察对足弓垫等矫形器材治疗扁平足的效果进行了肯定。……
