What are the basic 7 quality control tools used in apparel industry? ›

10-Point System

The 10-point system is another grading system that helps to determine the quality of fabrics. Under this system, quality inspectors assign the penalty points to each defect based on the length of the defects.

The 4 point system assigns 1,2,3,4 penalty points according to the size and significance of the defects. No more than 4 penalty points can be assigned for any single defect. Defect can be either length or width direction the system remains the same, only major defects are considered.

A check sheet is a structured, prepared form for collecting and analyzing data. This is a generic data collection and analysis tool that can be adapted for a wide variety of purposes and is considered one of the seven basic quality tools.

7.0 system is similar to the traffic light inspection system used by garment manufacturers. In the 7.0 quality inspection system, the roving quality checker visits each operator working in a production line. The quality checker picks 7 garments from the work done by the operator and checks all the pieces.

Usually 8 to 10 spi is adequate to provide adequate seam strength and at the same time allow for quicker cycle times . More stitches per inch will help minimize seam grinning. Due to many of the operations being lockstitch, usually 10 – 12 spi is required to provide adequate seam strength.

In 4 point system fabric quality is evaluated by unit points/100 sq. yds. Points / 100 sq. yd. = ( Total points in roll * 36 * 100)/ (Fabric length in yards * Fabric width in inches)

methods are visual, microscopy, liquid or dye penetrant inspection, mag- netic particle inspection, eddy current testing, x-ray or radiographic test- ing, and ultrasonic testing.

How many types of garments inspections are there? ›

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.

The 4-point system is a point grading system for determining fabric quality. Under this system, points are assigned to the fabric defects based on the length or width of the defects. The defects are based on the following criteria: (Source: Medium) The total defect points are calculated per 100 square yards of fabric.

Accepted Quality Level (AQL):

AQL is one of the most frequently used terms when it comes to quality in the apparel export industry. As most of the acceptance decisions of the apparel shipments for the export market are made on the basis of AQL based sampling plans.

In process of using the Leeds Spectral Vision System (LSV), to search for bodily fluids or evidence, there may be the occasion with various fabrics, where wave-lengths and filter combinations that are normally used for specific stains, are unable to be readily visualized due to the fabric itself preventing the stain ...

Flowcharts are perhaps the most popular out of the 7 quality tools. This tool is used to visualize the sequence of steps in a process, event, workflow, system, etc. In addition to showing the process as a whole, a flowchart also highlights the relationship between steps and the process boundaries (start and end).

These seven basic quality control tools, which introduced by Dr. Ishikawa, are : 1) Check sheets; 2) Graphs (Trend Analysis); 3) Histograms; 4) Pareto charts; 5) Cause-and-effect diagrams; 6) Scatter diagrams; 7) Control charts.

For analyze, the common and special cause's 7QC tools are usually used. 7QC tools consist of [1] Pareto chart [2] Cause and Effect Diagram [3] Histogram [4] Scatter Diagram [5] Control Chart [6] Check sheet [7] Graph /Process flow.

A quality control checklist is basically a written guide for your products' contents, packaging, color, barcodes, appearance, possible defects, functions and special requirements. It's also sometimes called an “inspection criteria sheet” or inspection checklist.

This publication looked back at Dr. Ishikawa's seven basic quality tools. He believed that 90% of problems could be solved with these simple tools: histograms, cause and effect diagrams, check sheets, Pareto diagrams, graphs, control charts and scatter diagrams.

What is 5S in garments industry? ›

5S Concept

The 5S system comprises 5 steps namely Sort, Set in Order, Shine, Standardize and Sustain. The concept of 5S is similar to the PDCA cycle i.e. continuous improvement. One has to go through all the 5 steps on daily basis in order to develop an Ergonomic and efficient workplace.

ISO textile testing standards includes tests to ensure the colorfastness of dyed goods. A whole set of standards is in place for evaluating the electrostatic propensity of materials, or the degree to which they give off an electric shock if they're rubbed or come into contact with other materials.

Lean is an all-encompassing philosophy that takes the 5 M's (Man, Material, Machines, Methods, and Money) and harmonizes or helps orchestrate them together for the best possible outcome in your manufacturing operations. If you do not know the 5 M's, here's a brief overview of how the 5 M's relate to lean automation.

In clothing construction, seams are classified by their type (plain, lapped, bound, flat) and position in the finished garment (centre back seam, inseam, side seam). Seams are finished with a variety of techniques to prevent ravelling of raw fabric edges and to neaten the inside of garments.

Seam efficiencies of 60–80% are common but efficiencies between 80 and 90% are more difficult obtaining from garment seams. Low seam efficiency values indicate that the sewn fabric is damaged during sewing.

AQL depends on percentage defective or defects per 100 units. Percentage defective is used in the apparel industry for simply made products, components, and materials. It is calculated by taking the number of defective products, multiplying by 100 and dividing by the number of units inspected.

Fabric construction methods include weaving, knitting, felting, lacemaking, and bonding. Since the way a fabric is constructed determines how it looks, handles, and behaves, it is important to be able to recognize and tell the difference between common fabric construction methods.

The four different types of inspections conducted by FDA are pre-approval inspection, routine inspection, compliance follow-up inspection, and “for cause” inspection. Each is intended to help protect the public from unsafe products, but the focus and expectations of each type of inspection are different.

7 Levels of Inspection Explained

There are seven different levels of the NAS Inspection Program. Each level has a slightly different focus ranging from driver, vehicle, and goods. The most common inspections that you should be aware of are Level I, II, III, and IV Inspections.

What are the 5 types of quality control? ›

The four types of quality control are process control, control charts, acceptance sampling, and product quality control. While a control chart helps study changing processes over time, process control and product quality control help monitor and adjust products as per the standards.

The three phase system includes the preparatory, initial, and follow-up phases of quality control. During the preparatory phase, our team thoroughly reviews the task at hand, inspection and testing requirements, and all safety precautions with the workers who will perform the work.

FDA conducts several types of inspections to help protect consumers from unsafe products: pre-approval inspection after a company submits an application to FDA to market a new product. routine inspection of a regulated facility.

There are three main garment defect types in apparel quality control – minor, major and critical – and the severity of the fault depends on which category the problem belongs to.

Grading Between Sizes is combining two or more sizes from a graded nest to customize the fit of the pattern. Knowing how to grade between sizes (or blend sizes) is a simple way to customize fit to your unique shape when your body measurements fall into more than one size on the size chart.

The “grade rules” refer to the amount of change between sizes, for each measurement point. Grade Rules usually go 1″ from 0-10, 1″1/2 from 12-16 and 2″ up from the 18 with a 1/4″ length from size to size. So a size 4 will only be graded down 1″ (1/2″ in the front and 1/2″ in the back) to produce a size 2.

Fabrics are defined as the clothing material, which is made by weaving or knitting threads and is obtained from the yarn. They are made from tiny thread-like fibres. These fibres are twisted to make a yarn.

Decoding AQL level setting

For general consumer products inspection, AQL level is usually set at 2.5, which implies a zero tolerance for critical defect, 2.5 for major defects, and 4 for minor defects.

What does an AQL of 2.5 mean? ›

What Does 2.5 AQL Mean? AQL 2.5 means the acceptable level of major defective goods is 2.5% of the total order quantity. If the batch produced contains a defect level that exceeds 2.5% defects, then the quality of the product is not living up to the agreement.

As an example, consider an AQL of 1% on a production run. This percentage means that no more than 1% of the batch can be defective. If a production run is composed of 1,000 products, only 10 products can be defective. If 11 products are defective, the entire batch is scrapped.

CSV and RSV are the two terms commonly used in naming textile fabric shade variations. RSV stands for Running Shade Variation. The shade variation found along with the fabric length is called running shade variation. CSV standard for Centre Selvedge Variation. This type of shade variation found across the fabric width.

EA or EL - Elastane/Spandex.

CSV is a centre-to-selvedge variation (shade) caused by uneven dyeing. It is a critical issue in the open width fabric processing industry, where continuous and semi-continuous dyeing machines are used.

Quality control of finished garments is an inspection before the merchendise are shipped to the customer and is done when at least 80% of the order has been packed for shipping. This process helps to detect any defects and reduces the risk of complaints from customers.

A garment quality control checklist is a document used by textile manufacturers and suppliers that clearly outlines product specifications and quality requirements for a particular product.

A Pareto chart is a bar graph. The lengths of the bars represent frequency or cost (time or money), and are arranged with longest bars on the left and the shortest to the right. In this way the chart visually depicts which situations are more significant.

Check Sheet

This is used for collecting and analyzing information. This tool is compatible with a wide variety of applications. When to use this method? This is used to analyze the repetition of the data of the same problem or similar.

The four types of quality control are process control, control charts, acceptance sampling, and product quality control. While a control chart helps study changing processes over time, process control and product quality control help monitor and adjust products as per the standards.

What are the 4 stages of quality control? ›

When broken down, quality control management can be segmented into four key components to be effective: quality planning, quality control, quality assurance, and quality improvement.

7-Step Quality Control Process.

A quality control checklist is basically a written guide for your products' contents, packaging, color, barcodes, appearance, possible defects, functions and special requirements. It's also sometimes called an “inspection criteria sheet” or inspection checklist.

Quality standards are defined as documents that provide requirements, specifications, guidelines, or characteristics that can be used consistently to ensure that materials, products, processes, and services are fit for their purpose.

The Pareto principle, also known as the 80/20 rule, is a theory maintaining that 80 percent of the output from a given situation or system is determined by 20 percent of the input. The principle doesn't stipulate that all situations will demonstrate that precise ratio – it refers to a typical distribution.
