Product Quality Essay

List virtually important physical properties of the cloth. The properties of textile textiles are important for the control of quality, as well as for end go for determination. thither are some(prenominal) physical properties of fabric which affecting the cognitive operation and aesthetic of fabric. The first building blockary is fabric count, it influences thickness of the fabric. It is the number of ends or picks per edge for woven fabrics, or the number of wales or courses per inch for knit fabrics.Variation occurs because of the weaving or knitting surgery and from swallow uping processes. Usually the higher the fabric count, the get around the quality and the higher the cost. The second is fabric unit weight. It is the mass per unit area. It is expressed in peerless three ways ounces per square yard, ounces per analog yard, and linear yards per pound. It is signifi beart in determining both end use and quality. Moreover, it is fabric width. It means the distance f rom one edge to the other. Measurement is make perpendicular to the fabric edge, usually including the selvage area.The width is expressed in inches and is usually an average number of measurements taken at evenly detached 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 by dint of the process of laundry. It is undesirable property to the apparels. So the material has to be both shrink resistant or shrink recoverable, such as anti-shrink finish is to keep the fabric smooth and free from undesirable shrinkage. The last one is fabric thickness.It is the distance between the upper and lower surfaces of the material. It is measure chthonic 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 resistance or shrinkage tests. Generally speaking, the thicker the fabric is, the more comfor table in wearing. 6. What is the commonly used fabric inspection corpse? Mainly, two industry methods used are the Ten argue and Four acme systems. The most commonly used is four-point system.A tokenish of 10% inspection of fabrics is required. The four-point system derives its name from the basic grading rules that a maximum of four penalty points can be assessed for any unity defect. 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 achievement The following table shows the point system. Size of Defect Penalty Points distance 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 past 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 and so forth 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 lay down and the National Federation of Textile, in 1955. It is designed to identify defects and to assign severally 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 digression (ends) or weft (fill) direction. The following table shows the point system.
