A Reference Test for HVI Strength Measurements. Part 2: Experience with International Cottons
By Muhammad Naveed Arshad on Apr 4, 2019

WCRC WCRC2

ABSTRACT Using the Reference Test Method discussed in Part 1, cotton from a number of locations throughout the world were tested to establish or verify reference values. Test results for selected cottons were compared to conventional laboratory methods to demonstrate the relationship between methods. The results demonstrate that the Reference Test...

Comparative Analysis of Cotton Maturity Assessment Methods
By Muhammad Naveed Arshad on Apr 4, 2019

WCRC WCRC2

ABSTRACT Textile product quality plays an important role for the consumer in the light of Standard ISO 9000. Different parameters determine the quality of any textile product. Fabrics characterized by a high level of aesthetic appeal should be suitable in appearance and dyeing uniformity. Such properties as fiber maturity and its distribution, num...

A Reference Test for HVI Strength Measurements. Part 1: Description of Instrument and Hardware Requirements
By Muhammad Naveed Arshad on Apr 4, 2019

WCRC WCRC2

ABSTRACT The equipment used in the Reference Strength Tester working group is described. A normal length/strength measurement on a 910B module of a Zellweger Uster Spinlab HVI line is used to measure length distributions and record the force that is necessary to break tapered beards. The fibers are then cut in one specific location that permits it...

Modification of the HVI Software as an Essential Step Towards a Global Cotton Standardization System
By Muhammad Naveed Arshad on Apr 4, 2019

WCRC WCRC2

ABSTRACT Grade and fiber properties are the main cotton quality factors measured on the High Volume Instrument (HVI). The HVI is used in 63 countries around the world but HVI grading is only used in the USA. In order to apply instrument grading, all cotton producing countries should include their own national graces on HVI software so that cotton...

The Solutions for Controlling Fabric Barré
By Muhammad Naveed Arshad on Apr 4, 2019

WCRC WCRC2

ABSTRACT Spinning mills have many options in the raw material they purchase for producing yarns. This expansion in the availability of raw material has helped to reduce cost and to improve yarn quality and spinning efficiency. Traditionally, purchased cottons had well established seed varieties and growth regions. This resulted in few dying and fi...
