What are different methods of textile quality control?
Today, the demand for clothing, home decoration and upholstery has created the need for textile quality control standards. The purpose is to ensure that all materials meet specifications for design and production. For example, the quality control techniques with a spectrophotometer can measure the color of the fabric, while key checkpoints can provide a product of raw materials, substance durability and stitch strength. Textile quality control can also be followed by an industrial body that can store standards for measurements as physical properties and abrasion. Textile products
are often analyzed to determine how well they are designed if they are acceptable for the intended purpose and if they meet the needs of the target market. This usually requires evaluation of such criteria as product design specification, market requirements and subsequent care. Other criteria, including the adequacy of sewing and strengthening, the aesthetic attraction of the product and compare, such as environmental impacts can be considered. Analysis of youHTO information can start with a detailed product sketch.
Color measurement techniques routinely provide the next step in textile quality control. This is because colors must often be repeatable to accumulate clothing or upholstery. Many times a tool known as a spectrophotometer is used to measure reflected and transmitted colors in the fabric. The operators are, in turn, with numeric values that correlate with the color of the fabric. This allows manufacturers to determine whether it is necessary to modify the dying process, how well the substance will withstand the exposure to the elements and what formula is necessary to repeat the color for future production.
Critical checkpoints (CCP) often provide the product synopsis to ensure that indicators meet the expected performance. In the production of textiles, this system can test and monitor the accuracy from the design phase through manufacturing processes. For example, a prototype that is a model of the design of the intended PRoduct, can be checked for material behavior and components and analyzed on assembly processes, costs and fitness for purposes. The raw materials are also common CCPs that operators can test width, weight and fiber content. Depending on the intended final use of the product, the fabric may also be tested for durability, resistance to fold and shrinkage.
During production, CCP controls often occur on the strength of the stitch and seam to ensure that they meet the manufacturing specifications. Comparison with the intended tolerance can also be tested by seams. The final product, which often reflects the fruit control of textile quality, can be checked for size, adaptation and aesthetic attraction.
Inspection control procedures can also be controlled by industry -related body. In the United States, for example, it is known as the Association for Contractual Fabrics (ACT). Managing bodies such as ACT often store standards to control textile quality that help consumerstake informed decisions. Common measurements that ensure that fabrics perform according to industry standards are: resistance to flame to determine the resistance of the substance to the burning; resistance to measurement of color sustainability of fabric; Ultraviolet light resistance to measuring fading; physical properties that indicate the potential for pills and tears; and abrasion to determine any surface wear that may occur with friction. Information regarding these test results can be printed on product labels.
flame resistance can be tested by a vertical test, with the fabric located on the holder and exposed to open flame for a certain period of time. After the flame is removed, the length of the test sample may be measured according to local or national standards to form a classification. Determine the color, the fabric can be wiped with square cotton fabric under the controlled pressure for a certain period of time. The amount of color transferred to white test squares canthen be associated with a control chart and set an evaluation.
Ultraviolet light resistance is another important aspect of textile quality control. For this measurement, the substance can be exposed to a light that simulates the sun's rays. After specific time passages, a textile sampler with a gray scale can be compared to evaluate the degree of fading. Physical properties can be measured using a brush pill, folding strength or seam slipping test. The abrasion can be tested by placing the fabric on a flat surface and wipe it into motion by eight by eight pieces of wool fabric.
