Determining Raw Cashmere Fibre Micron Profiles in Scoured Bales
Determining raw cashmere fibre micron profiles in scoured bales requires core sampling, lipid extraction, and truncated bimodal histogram distribution analysis.
Woolen Count
Linear Density
A traditional measurement system for yarn thickness defines the linear density of woolen-spun threads using an indirect yarn count method. The woolen count represents the length of yarn produced from a fixed weight of clean fiber, such as the number of runs of sixteen hundred yards per pound. It indicates how fine or coarse the spun yarn will be.
Spin System
Yarns produced on the woolen system are bulkier and more hairy than those spun on the worsted system. Applying the woolen count system allows spinners to calculate the required draft and twist for these highly textured yarns. It ensures the roving is drawn down to the correct weight before twist is inserted.
Fabric Weight
The weight of a woolen blanket or heavy winter coat depends on the yarn count used in the weaving process. A low woolen count indicates a thick yarn that creates a warm fabric with high insulating properties. Designers utilize these counts to plan the warp and weft densities of the woven fabric.
Industrial Standard
Trade transactions for raw wool and spun yarns rely on these standardized count systems to establish fair pricing and material yields. For instance, if a spinner delivers a batch that deviates from the specified woolen count, the fabric density will change and the garment pattern pieces will not fit together correctly. Mill quality inspectors measure the yarn weight per unit length from sample skeins to verify compliance before starting the looms.
This prevents fabric reject and waste in subsequent garment manufacturing.
