可溶PVA伴纺高支纯棉色织面料的生产工艺路线

对用可溶性维纶(PVA)伴纺生产高支高密纯棉色织面料的两种工艺路线("纱线染色、织造、退维"和"纱线退维、染色、织造")进行分析和试验研究.研究结果表明:采用"先退维、后染织"的工艺路线,退维股线的强力较低,可织性差,进行产业化生产的难度较大;采用"先染织、后退维"的工艺路线,织造效率和布面质量能得到保证,可应用于产业化生产;色织布退维后,织物的白度降低,颜色变浅,但无明显沾色现象.     

Cranial Nerve Decompression Gasket

A series of cranial nerve decompression gaskets were prepared with fibers of different fineness and high crimp which were obtained in knit-de-knit texturing process by using different specification general polyethylene terepthalate( PET) multifilament bought from market. The physical properties of the gasket were evaluated comprehensively and biocompatibility was analyzed with MTT assay.

颅神经减压垫片的物理性能

采用不同规格的涤纶复丝,利用编织解脱法制得的高卷曲度纤维制备10种颅神经减压垫片.通过减压性能测试,客观评价减压垫片,再结合临床医生的主观评价,研究各种样品的物理性能,并建立减压垫片的纺织专业表征与生物医用要求之间关系,形成综合客观评价指标M值.结果表明:8#样品的物理性能最好,其M值与主观评价结果相符,因此,可采用M值来综合评价减压垫片的物理性能.     

Preparation and Research of a Bionic Woven Tracheal Stent with Horizontal Pipeline

The paper designed a bionic woven tracheal stent and the stent was a multi-layer tubular structure with a transverse pipeline.Polydioxanone( PDO) monofilament and β-hydroxybutyrate and β-hydroxyvalerate copolymers/polylactic( PHBV/PLA) multifilament were chosen as the tissue engineering tracheal stent materials,and chitosan was chosen as the coating material. This study selected appropriate basic fabric structures and prepared the tracheal stent by setting reasonable weaving parameters,then treated the sample with coating and heat setting. Radical compression performances of the horizontal pipeline and longitudinal pipeline of this tracheal stent were investigated,and the experimental results showed that the stent had good performance on radial supporting force and elastic recovery,which meant it could supply adequate supports for cell growth and tissue regeneration of tracheal lesions; the horizontal pipeline could provide a good experimental foundation for reconstruction of the cartilage ring.
