Have you heard of a yarn count? in specific have you thought what it means when you hear counts like Ne 30s , Ne 20s , Nm 30s ( list goes on...).

To make it simple I will use a simple term....

Do you like to wear a thick piece of cloth as your inner wear? For sure , not.. you would prefer preferably thinner cloth. The difference between a thinner and thicker cloth is the yarn used to make the fabric. How to differentiate one yarn to other? Here the numbering systems of a yarn comes.

Wide range of numbering systems followed worldwide. Most commonly used yarn numbering system is English Count ( Ne ) for regular short stable spinning, In case of worsted yarns or long stable spinning , Metric System ( Nm ) is widely used. What is that? How to differentiate between both?

A definition of Yarn Count is given by the Textile Institute (UK) : Yarn Count is number indicating the weight per unit length or the length per unit weight of yarn.

    • Tex=No. of grams per kilometre

    • English Cotton Count = No. of 840 yd lengths per lb

    • Woollen Count (YSW) = No. of 256 yd lengths per lb

    • Woollen Count (Dewsbury) = No. of yard lengths per oz

    • Worsted Count = No. of 560 yd lengths per lb

    • Metric Count = No. of kilometres per kilogram

    • Linen Count (Wet Spun) = No. of 300 yd. length per lb

    • Jute Count = No. of lb per 14.400 yd

    • Denier = No. of grams per 9.000 metres

    • Decitex = No. of grams per 10.000 metres.
