多组分仿毛织物的设计与生产实践

为解决常规仿毛织物透气性差、易起毛起球的问题,从纤维性能、织物组织、织物紧度等方面探讨仿毛织物产品的优化设计。利用涤纶、粘胶、天丝(Tencel)和羊毛纤维的纯纺纱或混纺纱交织织制仿毛织物,合理配置各纤维的含量,实现各种纤维性能的优势互补。通过生产工艺优化,生产的涤纶、粘胶、天丝和羊毛纤维四合一仿毛织物既保留了毛织物固有的蓬松、透气、保暖好的优良性能,又解决了常规仿毛织物透气性差、抗静电性能差、易吸尘、易起毛起球的缺陷,该织物综合性能优于纯毛织物,而价格低于纯毛织物,具有较好的性价比,为企业经济效益提供了新的增长点。

文章采用阳离子可染改性涤纶与细旦华绒■纤维混纺成纱,再与莫代尔、氨纶共同制成纬编织物,对其纺纱、针织、前处理、预定形、染色及成品定形过程进行了详细分析,并给出了各工艺环节的控制要点。所制得的成品面料物理指标符合国家标准要求:抗起毛起球等级为正面2~3级、反面2级;抗勾丝等级为正面4~5级,反面4级;耐水洗及耐摩擦色牢度均达4~5级。此外,面料手感软糯滑爽又略带身骨,在针织保暖内衣面料的开发与应用领域具有广阔的前景。

Change of SPARC expression after chemotherapy in gastric cancer

Objective： The expression of tumor biomarkers may change after chemotherapy. However, whether secreted protein acidic and rich in cysteine （SPARC） expression changes after chemotherapy in gastric cancer （GC） is unclear, qqais study investigated the influence of chemotherapy on SPARC expression in GC. Methods： Immunohistochemistry was used to analyze SPARC expression in 132 GC cases （including 54 cases with preoperative chemotherapy and 78 cases without preoperative chemotherapy）. SPARC expression of postoperative specimens with and without preoperative chemotherapy was assessed to analyze the influence of chemotherapy on SPARC expression. Results： SPARC was highly expressed in GC compared with the desmoplastic stroma surrounding tumor cells and noncancerous tissues. High SPAKC expression was correlated with invasion depth, lymph node, and TNM stage. After chemotherapy, a lower proportion of high SPARC expression was observed in patients with preoperative chemotherapy than in the controls. For 54 patients with preoperative chemotherapy; gross type, histology, depth of invasion, lymph node, TNM stage, and SPARC expression were related to overall survival. Further multivariate analysis showed that lymph node, histology, and SPARC expression after chemotherapy were independent prognostic factors. Conclusiou： SPARC expression may change after chemotherapy in GC. SPARC expression should be reassessed for patients with GC after chemotherapy.
