Garment Inspection

Pre-Production Inspection: This is done before production starts. It is done to crosscheck for final verification of Bulk fabric and trims materials, styling cutting way, manufacturing details and workmanship of the garment or pre-production sample as per the customer requirement.

1^st inline production inspection: This inspection is done at the start of production when first production output of particular style of garments is inspected; to distinguish possible discrepancies or variation and to do necessary corrections to be made bulk production. This type of inspection is done at preliminary stage of manufacturing of a style covering mainly style detail, general appearance, workmanship, measurements, fabric quality, Trims and components, Lot color, printing, embellishments and washing quality.

2^nd line Production Inspection: This inspection is done during production to ensure initial discrepancies have been corrected and rectified. This inspection is a follow-up of the 1 ^st inline production inspection and is generally carried out after 1^st line inspection when discrepancies have been detected at that time.

Final Random Inspection: This inspection is carried out when the production of the total quantity of an order or partial delivery is completed. A sample lot will be selected from the order and a percentage of the garments will be inspected, this percentage usually being stipulated by the buyer. The AQL sampling inspection system as specified by the buyer.

Once the samples are selected, each article is to be individually inspected. Defects detected during an inspection are buyer specific so therefore vary from one buyer to another. Defects are classified within the following categories:

• Critical Defect: A serious defect that can cause harm or injury to the user and/or result in a hazardous condition.
• Major defects: A defect that falls to meet the mandatory regulations directly affecting the usability, salability, safety and value of the merchandise or as specified by customer buyer are considered as major defects and are generally non repairable for example fabric hole, shading among panel, wrong measurement, foreign yarn, dye patches etc. The measurement tolerate level may vary from customer to customer.
• Minor Defects: A defect that does not adversely affect the usability of the product but does consists of a deviation from the original sample, and may affect the sale of the product. Some of these defects are due to workmanship and some can be repairable but still can deteriorate the serviceability of the merchandise for example stain, skip stitch, wavy bottom hem etc.

AQL stands for Acceptable Quality level. The AQL determines the maximum amount of admitted defective units in a sample. AQL, for purposes of sampling inspection, can be considered satisfactory as a process average. The most commonly used AQL is a major 2.5 Minor 4.0. The AQL random sampling inspection is derived from the mathematical theory of probability and is based on the sampling these defined in military standard 105D (MIL - STD - 105D). Some defectives are considered acceptable.

This method constitutes taking random sample from a lot of merchandise, inspecting them and depending on the quality of the sample inspected determining whether the entire lot is acceptable or not. The MIS - STD - 105D (also BS 6001, ISO 2859, DIN 40080) provides the sampling plans; and these determine the number of samples of be inspected in lot size, in addition to indicating and the acceptable quality level (AQL) which represents the maximum number of defects per hundred units that, for the purpose of the sampling inspection can be considered satisfactory as a process average.

In general cases the buyer will determine which sampling plan and what AQL to adopt. The AQL 1.5 is applied when severe inspection conditions are required for expensive items like up market or Boutiques. The AQL 2.5 is applied when textiles or normal/good quality are involved. There are three types of sampling plans. Each sampling plan can be performed at three levels, i.e. normal tightened and reduced, depending on inspection requirements and quality of the products. In the garments industry generally single and double normal sampling plans are applied. The sample size code letter table shows various lot sizes corresponding to a series of code letters. There are seven inspection levels, four for general inspection (already mentioned) and three for special inspection. For garment inspection, general inspection level II (normal II) is normally applied.

Single sampling plan - Normal inspection

Assurance as AQL 2.5% and a lot of 1,200 garments and the sample size is 80 garments. If the number of defective garments found are 5 the total lot is "Acceptable" suppose if the garments found is 6, the total lot is "Reject/Re-Check".

Double sampling plan - normal inspection

Assurance an AQL 4.0% and lot size is 1,200 garments and the sample size is 80 garments. If the number of defective garments found is 7, the total lot is "Acceptable" suppose if the defective garments found are 8, the total lot is "Reject/Re-check". Today most of the customer demand for high quality products in low prices. So we should maintain the quality from the beginning stage of the production then only the final product with reach the consumer with right quality and we can get the order continuously from our customers. The garment manufacturers inspect their products continuously by designated responsible inspectors then only the right quality product will reach the consumers.

For pre-final inspection, selection of cartons from total cartons packed can be done based as shown table:
