Predicting th. Stitch.Density of Finish.d Fabrics Using Weft Blended Grey Knit Fabrics

Journal of Textile Science and Tech.ology 2024年第3期10卷 51-63页

作者： Kazi md. Elias Moh.mmad Obaidur Rah.an h. M. Zakir h.ssain Department of Ph.sics Jahangirnagar University Savar Bangladesh Jute Textile Wing Bangladesh Jute Research Institute Dhaka Bangladesh

Stitch.density is one of th. critical quality parameters of knit fabrics. Th.s parameter is closely related to oth.r ph.sical quality parameters like fabric weigh., fabric tigh.ness factor, fiber types, blend ratio, yarn diameter and linear density, and fabric structure. Selecting stitch.density (wales per inch. course per inch. is essential to getting th. appropriate fabric weigh. and desired quality. Usually, no rules or assumptions exist to get th. desired stitch.density in th. finish.d fabric stage. Fifteen types of blended knit fabrics were prepared to conduct th. study. Th. varying percentages of cotton, polyester, and elastane are incorporated in th. blends. Regression analysis and regression ANOVA tests were done to predict th. stitch.density of finish.d fabrics. A suitable regression equation is establish.d to get th. desired results. Th. study also found th.t th. stitch.density value in th. finish.d stage fabric decreases by approximately 15% compared to th. stitch.density in th. grey fabric stage. Th.s study will h.lp th. fabric manufacturers get th. finish.d fabric stitch.density in advance by utilizing th. grey fabric stitch.density data set. Th. auth.r expects th.s research.to benefit th. knitting and dyeing industry, new research.rs, and advanced research.rs.

Background: As th. h.lf-life of intact parath.roid h.rmone (iPTh. is very low, it reflects parath.roid insufficiency with.n minutes to h.urs after total th.roidectomy. Th.refore, iPTh.level assessment in th. postoperative period can be used to predict th. development of h.pocalcaemia. Th. optimal time point to measure serum iPTh.is important for th. accurate prediction of h.pocalcaemia. Aim: Th.s paper aims to evaluate th. ability of iPTh.as an early predictive marker of h.pocalcaemia and determine wh.ch.time iPTh.is more able to predict postoperative h.pocalcaemia. Meth.d: Th.s prospective observational study was conducted in th. Department of Otolaryngology-h.ad & Neck Surgery, BSMMU, Dh.ka, from July 2020 to December 2021, with.67 patients wh. underwent total th.roidectomy. iPTh.levels were measured on th. day before th. operation and at 1 h.ur, 4 h.urs, and 24 h.urs after th. operation. *** levels were measured on th. day before th. operation and 1st postoperative day. All th. data were compiled and sorted properly and were analyzed statistically. Results: Postoperative h.pocalcaemia developed in 18 cases, with.an incidence of 26.9%. Pearson correlation sh.wed a significant correlation between postoperative iPTh.at 1 h., 4 h. and 24 h. with.1st postoperative calcium value. Th. Receiver operating ch.racteristic (ROC) curve was processed for th. postoperative iPTh.at 1 h., 4 h. and 24 h.. Th. sensitivity, specificity, cut-off value, and mean AUC found 93.9%, 94.4%, ≤14.0, 0.988;95.9%, 94.4%, ≤09.5, 0.993 and 91.8%, 94.4%, ≤11.0, 0.993 respectively. Conclusion: iPTh.can be used as an early predictor of post-th.-roidectomy h.pocalcaemia. 4 h. iPTh.sh.wed more sensitivity and specificity for a cut-off value near th. laboratory reference range.
