NEWS - NINGBO TEXSCI YARN TECHNOLOGY CO.,LTD

Yarn is a kind of textile, processed into a certain fineness of products with various textile fibers, used for weaving, rope making, thread making, knitting and embroidery, etc., divided into short fiber yarn, continuous filament yarn, etc. Yarn fineness can be expressed in a variety of ways, such as number, metric count, imperial count, Denier, etc. (see count). The twist of the yarn is expressed as the number of twists per meter or inch. Woolen yarn and wool are generally used for weaving woolen sweaters, woolen trousers, woolen vests, scarves, hats and gloves, and weaving various spring and autumn season clothing items, in addition to warm and decorative role. So what does yarn testing test?

Yarn detection range
Yarn yarn, blended yarn, polyester yarn, pp yarn, special yarn, thick special yarn detection, braided yarn detection, etc.

Yarn inspection items
Component detection, quality detection, moisture content detection, color fastness detection, twist detection, physical property detection, oil content detection, physical index detection, etc.

Yarn testing standard
1GB/T 398-2018 cotton grey yarn
2GB/T 2543.1-2015 Determination of twist in textile yarns - Part 1: Direct counting method
3GB/T 2543.2-2001 Determination of twist in textile yarns - Part 2: untwist and twist method
4GB/T 2696-2008 jute yarn
5GB/T 3291.1-1997 Textiles - Textile materials - terms for properties and tests - Part 1: fibres and yarns

Characteristic parameter
1) Volume density: reflects the fiber packing characteristics;
2) The twist Angle of the fiber, crimp, etc. : reflect the degree of straightening of the fiber along the yarn axis;
3) Number of strands and twist direction of strands:
4) Linear density (diameter) and coefficient of variation: reflect yarn thickness and change
5) The force between the fibers (friction factor, entanglement, acting fragment or slip length, etc.) : reflects the stability of the yarn structure
