Thread Numbering System

Thread Numbering System Sewing Thread: Sewing thread is an essential element of garments. Sewing threads are special kinds of multi-layer yarn that are engineered and designed to pass through a sewing machine rapidly. It can be made out of many different materials including cotton, linen, nylon, and silk etc. According to Oxford Dictionary, “A thread […]

Systems of Yarn Count Measurement

Systems of Yarn Count Measurement What is count/yarn count ? Count or yarn count is a numerical expression which indicates the coarseness or fineness of a yarn. In other words, yarn count is a number indicating the mass per unit lengh or the length per unit mass of the yarn. There are mainly two systems […]

Length parameters of cotton fibers

The most frequent length in a fibrous sample is called staple length. Staple length is one of the most important factors of cotton quality because both fiber fineness and fiber tensile strength are associated with staple length. The longer staples are usually finer and stronger than the shorter staples.

Fiber length measurement

The fiber sorter is an instrument which enables the sample to be fractionalized into length groups. The Baer sorter, the Shirley comb sorter, and the Suter-Webb sorter are the most popular method of the fiber sorter. Basically, the operation involves four main steps: Preparation of a fringe or tuft with all fibers aligned at one end. The separation or withdrawal of fibers in order of decreasing length. The preparation of a sorter diagram by laying the fibers on a black velvet pad in decreasing order of length, the fibers parallel and their lower ends aligned along a horizontal base line as shown in Figure. The analysis of the sorter diagram.
