News > Fabric Inspection Machine Helps To Look Out Common Fabric Defects

As a garment manufacturer and importer, customer satisfaction and quality are the utmost requirements. However, there comes a problem with every supplier – quality control and check. A fabric must match the set standards in the textile industry without having any defect or shade variation. 

But as the defects sometimes are not readily visible, fabric inspection becomes very important before production. In this course, the suppliers and manufacturers require a well-built fabric inspection machine that will help them find the defects and avoid material wasting. 

But do you know how a fabric is inspected for defects and variations? Let’s learn the process explained below.

10 common fabric defects found during quality inspection:

1. Horizontal line formation

Horizontal lines are common defects caused by faulty bobbin and irregular tension in the thread. The irregular lines are spotted running from one side to another. 

2. Variation in color & shades

Shade variation is a common visual defect found on raw textiles. The variation could be defined by variation in depth of colour between roll to roll, piece by piece, etc. The most common reasons are fabric mixing, variation regarding speed and time, and fabric stretching. 

3. Dye marks and uneven dyeing 

When manufacturers use low-quality fabric, incorrect pH, and improver leveling, the dye marks are common to be seen. The issue also occurs due to the entanglement of the dyeing machine, which can be prevented with attentive care. 

4. Dirt patch or stain

In dyed textiles, stains are common issues. These are seen as discoloured patches and can occur anytime during textile production. Therefore, the textile or finished product should be kept in a safe and adequately protected area. 

5. Missed stitches

This is a commonly found defect, mostly in raw textiles. Visibly missed stitches are holes that appear randomly due to incorrect yarn carrier setup, knots or loose stitching. To avoid this issue, the tension should be perfect during fabric production. 

6. Wrong printing 

Missed prints or wrong prints defects are only limited to printed fabric cases. This defect occurs when the prints do not match the specified design. It can be considered in two distinct ways, either colour is missing, or patterns are incorrect. 

7. Barre

It is repetitive patterns of continuous stripes and bars that are unintentional. Barre generally appears as dark bars or horizontal streaks of light. In addition, detection of Barre is a little tough. It is only visible at the end of the process. 

8. Abrasion marks 

Abrasion marks are caused due friction and rubbing. The damage is more like discolouring of the area. In more professional terms, it is known as Chafe Marks. 

9. Knots (Neps)

Also called Neps, these are unorganized fibre masses that seem tangled not on fabric. The main cause behind knotting is an accumulation of dead fibres. Neps have three common types, mechanical, biological, and white speck.

10. Holes 

A fabric imperfection in which one or several yarns are sufficiently damaged to create an opening.

How are these defects detected?

These quality issues must be checked, marked and removed to not only ensure that the finished garment quality is good but also reduces rejects, improves efficiency and timely deliveries. Fabric inspection is of great importance in the fabric manufacturing industry, and fabric inspection machine is a necessity. But you need to have a reliable machine like FABRIC REWINDING-INSPECTION MACHINE PP-3L from Rexel Poland. The machine comes with a standard backlight, length measurement device and winding unit.
