Fabric Inspection 10-Point System

#Textile #Gate #Tf_Gate #Testing #FabricTesting #FabricGrading #Fabric #FabricInspection 10-point Fabric inspection system: It is one of the Fabric inspection systems where a maximum of 10 penalty points can be awarded to one defect. 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

Disadvantages of Ring Spinning

#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

#Textile #Fabric #Coverfactor #Gate Fabric Cover Factor: It is defined as the fraction of the area of the fabric covered by both warp and weft yarns. It is calculated from the threads/inch in the threads/inch in the fabric and counts of the threads. Cloth Setting: It gives the density of thread spacing and is expressed as the number of threads over a convenient linear distance such as an inch or a centimeter.

Why fiber length?

#Textile #Fiber #Length #Gate Why fibre length? Quality assessment, Fibre breakage study, machine settings, combing efficiency, etc. The length of staple fibre is one of the most important characteristics. In general, a longer average fibre length is to be preferred because it confers a number of advantages. Firstly, longer fibres are easier to process. Secondly, more even yarns can be produced from them because there are fewer fibre ends in a given length of yarn. Thirdly, a

YARN CRIMP

#Textile #Yarn #Crimp #Gate #TextileCoach Crimp: Due to the interlacement of warp and weft yarns, a certain amount of waviness is imparted to the warp and weft yarns in a fabric. This waviness is called crimp. Hence the apparent length of a thread as it exists in the fabric is less than its straightened length. Crimp Percentage: It is defined as the mean difference between the straightened thread length and the distance between the ends of the thread while in the cloth, expre
