BS 946 is an International Standard that focuses on the method for the designation of yarns.
BS 946 describes two methods of indicating the composition of yarns, whether single, folded, cabled or multiple wounds.
The designation comprises linear density indicated in the Tex System, number of filaments in filament yarns, direction and amount of twist, and number of folds.
Who is BS 946 - Designation of yarn for?
BS 946 on the method for the designation of yarns is useful for:
- Textile manufacturers

Why should you use BS 946 - Designation of yarn?
Yarn is a product of substantial length and a relatively small cross-section consisting of fibres or filaments with or without a twist. It is the long fine structures capable of being assembled or interlaced into such textile products as woven and knitted fabrics, braids, ropes, and cords.
BS 946 helps to assist factors or parameters which are required to express the yarn structure and properties are called yarn designation.
The factors are:
- Yarn count
- No. of filaments
- No. of components in folding
- Direction and amount of twist
- No. of components in cabling
- Fibre components
With compliance and obedience to BS 946, you can efficiently designate the yarns, to enhance the efficacy of the fabrics and manufacture a standardized product of high quality.
