…contains the methodology for the analysis of fabric defects

… required basic  tools, properties of fibers, yarns & their technological significance

… some well known and typical fabric defects & corresponding remedial actions.

…. contains selective case studies of defects in woven and knitted fabrics and the methodology adopted to analyze their causes.

…..each case is presented with a motto that fabric defect should not be treated as passing loss but as an opportunity to learn more about the root causes to reduce value loss.

Contents

  • This book contains valuable experiences of ATIRA spanning over last three decades on fine tuning of ring frames including the latest ones across the world. 

  • Describes refined maintenance practices/techniques developed by ATIRA and demonstrated on many a modern mills shopfloor through coloured photographs and schematic diagrams which have resulted in 3 to 15% ringframe productivity improvement, control of  consistency of various yarn quality parameters within and between bobbins and reduction of power consumption without investment.  Several case studies and results are given.

  • Gives conceptual inputs to practicing shopfloor technicians/students on genesis and requirement on precision of  ring frame subassemblies and components.

  • Contains ATIRA’s fundamental research on certain ring frame aspects.

  • A unique must keep book for every mill engaged in spinning activity in cotton/denim/polyester/ jute/worsted/synthetics spun on ring frame/com-pact spinning frame and like machines specially so in today’s global recession period.

  • It can serve as textbook for textile students.

Compendium of Fibre Characteristics of Certain Indian Cotton Varieties

Author : Seema Patel

ISBN No. : ISBN 978-81-908338-3-7

Price : Rs. 2000/-

Traditionally, Denim is a sturdy all-cotton twill fabric made with indigo-dyed yarn 

… a work wear fabric which later became popular as leisure wear

 

 ….favorite of high-fashion designers.

 

This book presents a whole gamut of the denim manufacturing starting from fiber to fabric, ….technology of indigo and sulphur dyeing, finishing, QA, product development, garment processing…..and effluent treatment.

Price : Rs. 600/-

…... Quality of Cotton has financial implications as well as Technological bearing. 

….. Quality of Cotton is important not only to Breeders and Farmers but also to Ginners, Spinners…….

…. Cotton classification has relied on instrumental measurement of properties.

…..  ATIRA has been extending Cotton testing facility to Ginners for last 50 years.

…. ATIRA has been working towards compiling data on Indian Cotton Varieties in terms of HVI quality parameters to help Indian trade and Industry  This compendium provides information on fibre characteristics of about 30,000 samples of cotton received and analyzed during October 2006 to March 2007.

The properties of cotton samples from various stations are given in terms of UHML (Upper Half Mean Length), ML (Mean Length), UI (Uniformity Index), SFI (Short Fiber Index), MIC (Micronaire), Rd (Degree of Reflectance) and ‘b’ (Yellowness).
