Confused About Quality Control Systems in Textile? Need Help Deciding!

Suppose you are working in the quality department of a textile unit. Your job responsibility is to test the color of the fabric. Being the quality controller, what quality control system from the following will you adopt? Justify your answer.

Quality Control Systems

JIT
GANTT CHART
PERT

In my opinion, none of the above refers to quality control. I need your assistance to let me know whether I am wrong or right.

You can prepare a master color sample and get it approved by the customer. Since colors tend to fade, it is important to maintain the validity of the master sample and establish a fixed frequency for changing the master. Keep a regular schedule for changing the masters and obtaining approval.

Ensure that the colors match and consider creating an attribute control chart with a "Yes" or "No" type for the samples you produce.

Thank you.

I do not know whether you want to test others in this forum or you want some help in formulating your assignments. Anyway, here is the required information.

Basic Requirements for Fabric Color Testing

First, for any fabric color testing, there are the following basic requirements:

• There are PANTONE color shades which are widely accepted as standard shades. You can match the color of the fabric with specific shades of the PANTONE sheets. You can flag the variations every ten/twenty-five/fifty/hundred meters.

• The quality control system has to have major and minor shade variations - depending on the type of fabric/dye/yarn. The spread of colors on the yarn has to be tested before the fabric is tested. This decides the uniformity of the fabric color.

• Based on the number of variations found per every specified length (i.e., ten/twenty-five/fifty meters, etc.), you may do the root cause analysis and arrive at a solution.

• You may also adopt a first-time right approach by yarn color inspection to avoid post-weaving analysis.

• If you have baking/oven cure for fabric for stabilization of color or singeing (flame curing), then you may keep the temperature variation charts to understand the effect on the fabric color variation and make a stage-wise analysis.

Hence, all the tools of problem-solving can be used based on your process sequencing and data analysis capacity.

If you want to "test the color of fabric," then you need proper testing equipment. This could involve color matching if you want to match the color or color fastness if you want to test color retention.

JIT, GANTT CHART, and PERT in Textile Manufacturing

JIT, GANTT CHART, and PERT have nothing to do with "color testing" or even routine "Quality Control" activities in textile manufacturing.

JIT (Just-In-Time)

JIT: Inventory items arrive when they are needed in the production process instead of being stored in stock. The ultimate goal of a JIT inventory system is to eliminate raw material inventories by coordinating production and supply deliveries precisely.

GANTT CHART

GANTT CHART: A scheduling/planning tool that shows in a bar graph form when tasks are supposed to be done and compares that with the actual progress on each, especially in project management.

PERT (Program Evaluation and Review Technique)

PERT: A flowchart-like diagram depicts the sequence of activities needed to complete a project and the time or costs associated with each activity.
