Product Quality Essay Example for Free

Product Quality EssayList some important physical properties of the material. The properties of cloth materials argon important for the control of prime(a), as well as for end part determination. There are several physical properties of fabric which affecting the performance and aesthetic of fabric. The first one is fabric count, it influences burdensomeness of the fabric. It is the number of ends or picks per inch for woven fabrics, or the number of wales or courses per inch for knit fabrics. interlingual rendition occurs because of the weaving or knitting process and from finishing processes. Usually the higher the fabric count, the better the caliber and the higher the cost. The second is fabric unit weight. It is the mass per unit area. It is expressed in one trio ways ounces per square yard, ounces per linear yard, and linear yards per pound. It is significant in determining both end use and quality. Moreover, it is fabric width. It means the distance from one edge to the other. Measurement is made perpendicular to the fabric edge, unremarkably including the selvage area.The width is expressed in inches and is usually an average number of measurements taken at every bit spaced interval along the fabric pieces. Next one is fabric shrinkage. It is the process in which a fabric becomes smaller than its original size, usually through the process of laundry. It is undesirable property to the apparels. So the substantive has to be either shrink resistant or shrink recoverable, such as anti-shrink finish is to salve the fabric smooth and free from undesirable shrinkage. The last one is fabric thickness.It is the distance between the pep pill and lower surfaces of the material. It is measure under a specific pressure. Warmth and bulk properties depend on the fabric thickness- to-weight ratio. It can also be used as a performance indication of abrasion opponent or shrinkage tests. Generally speaking, the thicker the fabric is, the more comfortabl e in wearing. 6. What is the special Kly used fabric take stockion system? Mainly, two industry methods used are the Ten intend and Four point systems. The most commonly used is four-point system.A minimum of 10% inspection of fabrics is required. The four-point system derives its name from the staple fibre grading rules that a maximum of four penalty points can be assessed for any single stigma. Normally, we inspect 10% of the rolls we receive and evaluate them based on this system. This way, we can avoid fabric related quality problems before it is put into production The following table shows the point system. Size of Defect Penalty Points duration of defects in fabric (either length or width) Defects up to 3 inches 1Defects gt 3 inches lt 6 inches 2 Defects gt 6 inches lt 9 inches 3 Defects gt 9 inches 4 Holes and openings(largest dimension) 1 inch or less 2 Over 1 inch 4 After inspection, the inspector will add up the defects points and and so use the following formula to determine the rate of points per 100 yards. There are some common fabric faults, such as bow, skew, hole, mispick etc. Fabric checker should know common defects found in fabrics and he must recognize defects on the fabric at the time of fabric inspection.For the acceptance criteria and calculation, 40 points per 100 yards is the acceptable defect rate. The ten point system for piece goods evaluation was approved by the Textile distributors institute and the National Federation of Textile, in 1955. It is designed to identify defects and to assign each defect a value based on severity of defect. The system assigns penalty points to each defect depending on its length and whether it is in the warp (ends) or weft (fill) direction. The following table shows the point system.
