the defects of fabric are the types of fabric, and how you use the sewing machoine.

Satin fabric defects can include issues like snagging, uneven weave, and improper dyeing, which can lead to color inconsistencies. Other common defects may involve puckering, where the fabric does not lie flat due to tension during the manufacturing process, and fraying at the edges. Additionally, imperfections such as spots or stains can occur, affecting the overall appearance and quality of the fabric. Regular quality control during production can help minimize these defects.
The 4-point fabric inspection system is a quality control method used primarily in the textile industry to assess fabric defects. Under this system, defects are categorized based on their severity and the size of the area affected. Each defect is assigned points: 1 point for minor defects (less than 1 inch), 2 points for medium defects (1 to 3 inches), 3 points for major defects (3 to 6 inches), and 4 points for critical defects (over 6 inches). The total points accumulated from the defects found in a specific length of fabric determine its quality rating, guiding manufacturers in making decisions about fabric usage and potential rework.
Weaving defecting refers to flaws or irregularities that occur during the weaving process of textiles. These defects can include issues such as uneven tension, misalignment of threads, or inconsistencies in the fabric's pattern and texture. Such defects can compromise the quality and aesthetic appeal of the final product, making quality control essential in textile manufacturing. Identifying and addressing weaving defects helps ensure a high standard in fabric production.
Fabric faults are responsible for major defects found by the garment industry, say Saber Ben Abdessalem, Meriam Azeiz, and Sofiene Mokhtari, who also propose a new inspection method permitting to appreciate objectively fabric quality.
The formula for fabric consumption can be calculated using the following equation: [ \text{Fabric Consumption (yards/meters)} = \frac{\text{Total Garment Area (square yards/square meters)}}{\text{Width of Fabric (yards/meters)}} ] To determine the total garment area, you need to consider the pattern pieces, seam allowances, and any additional fabric for design elements. Always account for wastage as well, typically adding an extra percentage for cutting errors and fabric defects.

Latent defects are not obvious and are not easily discoverable while patent defects are obvious.
At an Acceptable Quality Level (AQL) of 1.5 for a batch of 5,000 garments, the major quality defects are those that significantly affect the garment's functionality or aesthetic, such as incorrect sizing, severe stitching issues, or fabric flaws. Minor quality defects are less impactful and might include minor stitching irregularities or slight color mismatches. For a 5,000-piece lot, AQL 1.5 typically allows for a maximum of 75 defects (major and minor combined), with a stricter limit on the number of major defects. Thus, maintaining quality standards is crucial to minimize both types of defects.
Wastage factors considered for fabric booking typically include cutting waste, which accounts for the excess fabric lost during the cutting process, and defects, which refer to flawed sections of fabric that cannot be used. Additionally, allowances for shrinkage and pattern matching may be factored in, especially when working with printed or patterned fabrics. Transportation and storage losses can also be considered, ensuring that the total booked amount accommodates these potential inefficiencies.
