How to Inspect for the Best Coverall?

Table of Contents

As one of the China’s leading coverall manufacturers since 2009, we are responsible for each coverall we have produced for our clients. Here we would like to share how to inspect for the best coverall.

Using damaged or worn-out coveralls can be risky, especially in industries like construction, manufacturing, or chemical processing.  There could be many potential problems without proper inspections. Below are some of the common quality defects: restricted movement, frayed edges, torn seams, or stiffened fabric, loss of visibility and etc. To ensure the work-wear coverall is functional, comfortable to wear and safe for use,  especially in hazardous working environments, it’s quite essential to do inspections.

1. Key Areas to Inspect for the Best Coverall

1.1 Physical Damage Check

Tears and Holes: Any visible rips, tears, or holes in the fabric, especially around reinforced areas like the padding, knees, elbows, pockets and seams can compromise the coverall’s protective ability. Details could be the God, determining if it is a quality coverall.

Seam Integrity: Frayed seams or loose threads mean that the coverall could come apart during use. After all, the rotten apple injures its neighbors.

1.2 Zippers, Snaps, and Closures

Zippers and Snaps: Ensure that all zippers, snaps, and buttons are functioning properly. Broken closures can leave parts of the body exposed and reduce protection.

Velcro and Elastic: Check that Velcro strips and elastic bands are strong and secure.

2. Fabric Inspection

2.1 Gram Weight Measurement

Gram weight is usually in GSM, short for gram per square meter. It’s a key factor in determining the thickness, durability, and heaviness of fabric. So it would be one of the most important aspects for quality check of the work-wear coveralls. Use a professional cutter to cut a piece of fabric and then get its weight with a high-precision small scale. And then we can get the right gram weight.

2.2 Even Fabric Thickness

Even fabric thickness of a coverall impacts the fabric’s durability, appearance, and overall quality.Uneven thickness can lead to issues like weak spots and inconsistencies in wear. Hold the coverall up to a light source and you will easily find if there are any defects.

2.3 Abrasion & Common Fabric Comments

Fabric abrasion can result in a reduction in the fabric’s strength, appearance, and durability. It often comes with some common fabric defects like pilling, fuzzing, snagging and broken or frayed fibers.

Pilling: Small, fuzzy balls of fiber can happen, especially when fabrics with shorter fibers (like cotton) or synthetic blends are more prone to pilling. 

Fuzzing: The loosening and raising of fibers on the fabric surface makes fabrics appear rough and reduces smoothness.

Snagging: A pulled thread or loop on the fabric’s surface caused by something sharp catching the fibers can lead to further unraveling, reducing the durability and appearance of the fabric.

Broken or Frayed Fibers: Broken fibers could lead to fraying along the edges or the fabric’s surface.

The weakened areas can eventually result in holes or tears.

2.4 Fabric Composition

Nay to say, it’s very significant to ensure the right fabric is used for coverall production. There are many methods to help us distinguish the different fabrics.  We can make it through visual and tactile inspection, burn test, water absorbency test, wrinkle test, heat retention test or static electricity test.  

Cotton is Matt-finished, water-absorbent and easy to get wrinkled. Cotton coveralls feel soft, smooth, breathable and cool to touch. Coveralls made from cotton rarely cause static cling;  Polyester is shinier, hydrophobic and more slippery. Polyester coveralls can resist wrinkling well, retain heat but build up static easily; Cotton/polyester blend fabric is somewhat between cotton and polyester fabric.

Here below we are going to introduce in details about a most reliable way for fabric composition confirmation -burn test.

Cotton burns quickly with a bright flame. It smells like burning paper or wood because it is a natural cellulose fiber.

  • Ash Residue: The ash is soft, grayish, and turns to powder easily.
  • After Burning: Cotton continues to burn after being removed from the flame and does not melt.

Polyester melts and shrinks away from the flame. It burns slowly and drips as it melts, and it emits black smoke. It smells like burning plastic or chemicals.

  • Ash Residue: The residue is hard, shiny, and plastic-like.
  • After Burning: Polyester stops burning when the flame is removed because it melts rather than fully combusting.

The features of cotton/polyester blend are between cotton and polyester fabrics.

3. Identifying Contamination and Residue

Check for any stains or residues from oils, chemicals, or other substances that could weaken the fabric or pose a safety hazard. Ensure it has been properly cleaned and decontaminated.

4. Ensuring Proper Fit and Comfort

4.1 Fit Check

The coverall shall fit properly. It shall not be too tight or too loose. A poorly fitting coverall can restrict movement or leave parts of the body exposed. Follow strictly the size chart and meanwhile check it based on real uses.

4.2 Comfort Features

Perform a simple mobility test by bending, squatting, and reaching to see if the coverall allows free movement without discomfort or strain; Over time, elastic components or fabric can stretch, leading to a loose fit. Quality waistbands are more than important; Pay attention to the quality of padded areas for better durability.

5. Inspecting Safety Features and Reinforcements

5.1 Reflective Strips and Visibility Features

For coveralls with reflective strips, the reflective tapes must be in good condition and not peeling or fading. Damaged reflective material can reduce visibility in low-light environments.

5.2 Reinforced Areas and Padding

Inspect reinforced areas (such as knees, elbows, and seat) to ensure that the extra layers are intact and well stitched for the intended level of protection. And check the pockets or tool loops to ensure they are functional and free from damage.

5.3 Lining and Insulation (for cold-weather coveralls)

Insulated Coveralls: For cold-weather or thermal-protection coveralls, check the lining in case of any bunching, or damage. Damaged insulation can reduce the coverall’s ability to keep the wearer warm or protected.

6. Manufacturer’s Labels and Care Instructions

Check the contents of the label about the special care instructions or safety warnings to ensure there are proper recommendations for maintenance.

Conclusion

Coverall inspection to guarantee the quality of the whole batch of goods. Selecting a reliable and professional safety coverall manufacturer does help save lots of time, energy and inspection costs for each order.
