This system was introduced in 1955 which was adopted by Textile Distributors and the National Federation of Textiles. This is the earliest inspection system and is designed to identify defects and assign each defect a value based on the severity

#Textile #Spinning #RingSpinning #Gate #Tf_Gate Following are the disadvantages of choosing Ring Spinning Process Process stages are more numerous, Roving stage exists as an extra process compared to the other systems. Yarn breakages are more numerous as a result of ring traveler friction and yarn air friction. interruptions, broken ends, and piecing up problems exist because of the yarn breakages. The high speed of the traveler damages the fiber. The capacity of the cops is

Ans: C.V. % = 1.25 X U% The irregularity U% is proportional to the intensity of the mass variations around the mean value. The U% is independent of the evaluating time or tested material length with a homogeneously distributed mass variation. The larger deviations from the mean value are much more intensively taken into consideration in the calc

Ans: Too high tension: Can damage the yarn. The breakage rate may be greater. Elongation properties may change. Too low tension: Can lead to unstable or loose packages which will not unwind cleanly. Variation in yarn tension in different parts of a wound package can cause undesirable effects. For MMF: Too high tension

(or) A count is a number indicating the mass per unit length or length per unit mass of the yarn. Principle: It is working on the principle of fixed weight and fixed-length system. It is used for assorting the count of warp and weft yarns from a small sample of the fabric. It consists of pillar A which carries a cross be

The threads of weft are called picks and the number of weft threads per inch is known as picks per inch (PPI). Determinat
