Technical textile is a textile product manufactured for non-aesthetic purposes, where function is the primary criterion.It is a large and growing sector and supports a vast array of other industries.This study was focused to enhance the application of the natural fibers in the field of technical textiles. Natural fibers are abundantly available on the Mother Earth. The fibers coir, jute, sisal and PET were used as raw materials for the study.These fibers were convereted into needle punched non-woven fabrics. The prepared fabrics were tested for the suitability in the selected fields of technical textiles such agro tech, build tech and geo tech .The results obtained from the prepared fabrics had given great recommendations for the future technical textile industry.

This study investigates the efficiency of manufacturing subsectors in the Zimbabwean economy. The study applied the panel data econometrics approach in the leading manufacturing subsectors from 1980-2005. The quantitative estimates using SFA shows that there are varying efficiencies across sub-sectors and through time. The log-likelihood test shows that there existed technical inefficiency in the production processes in the manufacturing sector. This shows that the industries could have improve their productive capacities with the same amount of inputs. The study shows that average technical efficiencies were falling since 1980 in the investigated sub-sectors. The highest efficiency scores were recorded in the canning and preservation of vegetables and fruits sub-sector which have an average of 98.1 percent efficiency level. The least efficient sectors are the textiles and footwear sectors which had averages of 32 percent and 33 percent efficient levels.

Chemistry For Textile Students; A Manual Suitable For Technical Students In The Textile And Dyeing Industries, By NORMAN BLAND. PREFACE. The present time, being one of reconstruction, is an opportune moment for the presentation of this work, as it is, we believe, the first attempt to put forward a fairly compIetecourse on Chemistry for Textile Students suitable for the large and growing number of students who are taking up the technical study d textile industries from the truly scientific standpoint. It is a noteworthy feature of the last Census of Production, published in 1907, that, if we omit coal mining, whilst the cotton and woollen industries occupy respectively the first and fourth positions among the nine leading industries of the country as regards number of people employed, yet these industrics employ a smaller percentage of well-trained technologists than any of the others. With one exception, the productivity, or net putput in value per head of persons empIoyed, is less in the case of textile industries, apart from chemistry and dyeing, than that of the other great industries of the country, and this is no doubt largely due to the small percentage of well-trained technologists employed. Apart from the branches of bleaching and dyeing, it is only in very recent years that it has been realised, and only then by the most enlightened employers, that chemistry and physics play a most important part in the various operations used in the production of yarns and finished pieces. Recently, however, it has been recognised that Germany, in pre-W-ar times, Pas getting far ahead of us, principally through the,direct application of the sciences of chemistry, physics, and engineering to the procksses of nlanufactue of textiles. Iarge manufacturers are now beginning to realise that specially trained textile-chemists and textile-engineers must be engaged for special research work, if progress is to be made which wi1l enable us to keep pace with the competition of other great natons of the world. Germany was setting the pace in prewar times, nvhilst our manufacturers were resting largeIy on the laurels of the past, with the result that certain branches of our great textile industry were fast passing to the continent but in the near future other great nations of the world will have profited by the experience of Germany, and, if we are to maintain the traditions of the past, me must bring the sciences of chemistry and physics to bear to a greater degree on the study of textiles. It is a necessary part of the training of the textile technologist, who will late be engaged in the production of yarns and finished articles, that he should have received a thorough grounding in the sciences of chemistry and physics.

Worsted Preparing and Spinning - Drawing and Sp...
75,90 CHF *
ggf. zzgl. Versand

Volume III of WORSTED PREPARING AND SPINNING. (DRAWING AND SPINNING). THE subjects dealt with in this volume are worsted drawing, including differential bobbin winding and mechanism, or cone drawing; French drawing; throstle spinning of the flyer, cap, and ring types; twisting; warp winding, and warping. Two comparatively long chapters are devoted to the subject of mechanical doffers for flyer and cap frames, which will be found to be fully considered and extensively illustrated. This book is the product of many years of practical experience, teaching, observation, study, and technical conversations. Many of the earliest books on weaving, textiles and needlework, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
