Sampling is a process of making a product prototype prior to starting bulk production. Sampling is one of the main processes in Garment Industry and it has a vital role in attracting buyers, because the buyers generally place the order after they are satisfied with the quality of the samples.
Sampling includes details like a product/style code or a reference number, color specifications, kind of fabric, composition, description, quantity, and details of embroidery, buttons, zippers, or any other sort of accessories used. Hence it can be said that sampling works as a bridge between buyers and manufacturers. Once the sample is satisfactory to the buyer, the buyer will confirm the order.
Once the fabric is dyed, the fabric has to go through a process called ‘compacting’.
Because the material is continually under tension throughout the various stages of the textile manufacturing process including knitting, dyeing, and other finishing processes, we should relax the fabric to shrink so that further shrinkage during customer use is minimized.
After the fabric has been relaxed, it is transferred to the spreading and cutting area of the garment manufacturing facility. The fabric is first cut into uniform plies and then spread either manually or using a computer-controlled system in preparation for the cutting process.
Next, garment forms—or patterns—are laid out on top of the spread, either manually or programmed into an automated cutting system. Lastly, the fabric is cut to the shape of the garment forms using either manually operated cutting equipment or a computerized cutting system.
Value addition is the process where we enhance the garment by adding some incentives to it. For example, a buyer may ask for his brand logo embroidery on the garment. In such case, the cut-panels are given for these processes before they go for stitching. There are some exceptionally value additions which are done on the fabric once the entire garment is stitched such as garment-wash.
Here are some of the value additions done on the fabric before stitching:
Stitching or sewing is done after the cut pieces are bundled according to size, colour and quantities. Garments are sewn in an assembly line, with the garment becoming complete as it progresses down the sewing line. Sewing machine operators receive a bundle of cut fabric and repeatedly sew the same portion of the garment, passing that completed portion to the next operator. For example, the first operator may sew the collar to the body of the garment and the next operator may sew a sleeve to the body.
Quality assurance is performed at the end of the sewing line to ensure that the garment has been properly assembled and that no manufacturing defects exist. When needed, the garment will be reworked or mended at designated sewing stations. This labor-intensive process progressively transforms pieces of fabric into designer garments.
It is realistic to assume that however well checking or quality control procedures operate within a factory there will always be a certain percentage of garments rejected for some reason or other. The best way to carry out quality checks is by
So there will be a team of quality checkers checking each and every garment. After a garment is fully sewn and assembled, it is transferred to the checking section for final checking of the garment.
This team not only identifies manufacturing defects but also looks for cosmetic flaws, stains, or other spots on the garment that may have occurred during the cutting and sewing processes. Spots are often marked with a sticker and taken to a spot-cleaning area where the garment is cleaned using steam, hot water, or chemical stain removers.
Once the packaging is completed, there will be a final inspection for the mass production. The packed garments are then inspected for quality assurance of the outgoing finished products. This process is followed for internal quality audit and to ensure that no defective garments are packed into the cartons.
The quality inspector collects samples from the whole inspection lot according to the standard sample size. The inspector only checks sample size items and detects defects and defective units from the sample size. We strictly follow AQL2.5 for quality measures.
In the AQL standard chart, it is defined that up to how many defective garments can be accepted. If the inspector founds more defective units (defects) in the sample size units than the acceptable limit, the whole lot will be rejected.
