1. Quality Control:
Quality control refers to the examination of test results and its application to the textile process, raw materials, intermediate goods, and finished products. It is concerned not only with the degree of quality and the expense of sustaining that level of quality, but also with the presentation of concrete values that may be used to assess quality and changes in quality. To manage quality, one must first understand what consumers demand. Quality Assurance
2. DEFINITION OF QUALITY:
Quality is defined as conforming to specifications. Quality may also refer to consistently meeting or surpassing a customer's expectations. Different sorts of consumer expectations exist. Quality expectations and the capacity to discern distinct quality features differ from one consumer group to the next. For example, more educated customers have more precise quality expectations, but less educated customers have less. As a result, the quality is divided into four distinct categories, as follows. 1) Quality of the product: The quality of a product-based definition of quality is mostly determined by the quality of the product. The manufacturing of a product has a greater impact on its quality.
3. User-based quality:
This simply refers to the quality of whatever the customer says or desires. In a nutshell, meeting or exceeding the needs and expectations of the customer. Manufacturing-based quality. This quality is defined as fulfilling standards or complying with requirements. It's all about manufacturing excellence. Any departure from the specifications indicates a lack of quality. 4) Value-based quality: In this form of quality, the cost of a product or service is taken into account more.

5. Quality Control Objectives:
1. Raw material selection Specification test 2. Product testing. 3. To verify that the product meets the intended standard of quality. 4. To ensure that quality standards are met. 5. Control and growth of processes 6. Various situations will necessitate different strategies for control. 7. Quality control, for example. 8. To make an accurate assessment of the final result. 9. devoted to research and development Quality control, for example. Quality Control Objective
6. The following two key elements of the quality management system can offer quality assurance procedures
Fabric GSM control Grey Fabric Inspection with 4 point method Diameter and Width control Shade Check; Bias and Bowing; Visual appearance (Enzyme performance); Stripe Off-line tests are separated into two categories: physical tests and chemical tests.
8.System of Quality Management:
1. Fabric weight in grams per square meter (gsm); 2. Crocking or rubbing fastness; 3. 4. Pilling test 5. Dimensions (diameter and width); 6. tensile strength 7. Tearing test 8. Bursting test Test for light fastness; 9. Course per inch; Drape, Stiffness, and Handle 10.Picks per inch; 11.Ends per inch; 12.Wales per inch Physical Examinations
9. Chemical Examinations:
1. Spirality or Twisting and Shrinkage; 2. Efficacy in the washing machine; 3. Perspiration Quickness; 4. Chlorine resistance; 5. A PH test was performed. Chemical Examinations
10.Quality assurance:
Quality assurance is defined as all of the potential planned and systematic efforts that are required to offer enough confidence that a product or service will meet specified quality criteria. The Quality Assurance Department is in charge of ensuring that the material in process and at various stages of production are of consistently high quality.
