Garments defects (Part 4)

Presented By : Shourov Hasan


Garment defects, classified according to the various manufacturing stages are:


Spreading defects in garment:

Not enough plies to cover quantity of garments required. Plies misaligned, resulting in garment parts getting cut with bits missing in some plies at the edge of the spread. Narrow fabric, causes garment parts at the edge of the lay getting cut with bits missing. Incorrect tension of plies, i.e. Fabric spread too tight or too loose. This will result in parts not fitting in sewing, and finished garments not meeting size tolerances. 

Not all plies facing in correct direction (whether 'one way' as with nap, or 'one way either way' as with some check designs). This happens when fabric is not spread face down, face up, or face to face as required. Unacceptable damages in the garment parts. Parts not fully included owing to splicing errors. Spread distorted by the attraction or repulsion of plies caused by excessive static electricity. Plies are not spread accurately one above another for cutting. This results in mismatching checks.


Cutting defects in garment:

Failure to follow the marker lines resulting in distorted garment parts. Top and bottom plies can be a different size if the straight knife is allowed to lean, or if a round knife is used on too high a spread. Notches, which are misplaced, too deep, too shallow, angled, omitted, or wrong type to suit fabric .drill marks, which are misplaced, wrong drill to suit fabric, omitted, not perpendicular through the spread. 

Frayed edges, scorched or fused edges, caused by a faulty knife, not sharp enough, or rotating at too high a speed. Knife cut. Garment part damaged by careless use of knife, perhaps overrunning cutting previous piece. Marker incorrectly positioned on top of spread. Garment parts have bits missing at edge of lay. If too tight or too loose then garment parts are distorted. Slits opened inaccurately or omitted.

Garment twist

A rotation, usually lateral, between different panels of a garment resulting from the release of latent stresses during laundering of the woven or knitted fabric forming the garment. Twist may also be referred to as torque or spirality.

There are certain quality related problems in garment manufacturing that should not be over looked:

Sewing defects - like open seams, wrong stitching techniques used, same colour garment, but usage of different colour threads on the garment, miss out of stitches in between, creasing of the garment, erroneous thread tension and raw edges are some sewing defects that could occur so should be taken care of.

Colour effects - colour defects that could occur are difference of the colour of final produced garment to the sample shown, accessories used are of wrong colour combination and mismatching of dye amongst the pieces.

Sizing defects - wrong gradation of sizes, difference in measurement of a garment part from other, for example- sleeves of xl size but body of l size. Such defects do not occur has to be seen too.

Garment defects - during manufacturing process defects could occur like faulty zippers, irregular hemming, loose buttons, raw edges, improper button holes, uneven parts, inappropriate trimming, and difference in fabric colours.

For every industry or business, to get increased sales and better name amongst consumers and fellow companies it is important to maintain a level of quality. In the garment industry quality control is practiced right from the initial stage of sourcing raw materials to the stage of final finished garment.

For textile and apparel industry product quality is calculated in terms of quality and standard of fibres, yarns, fabric construction, colour fastness, surface designs and the final finished garment products.

However quality expectations for export are related to the type of customer segments and the retail outlets. There are a number of factories on which quality fitness of garment industry is based such as performance, reliability, durability, visual and perceived quality of the garment. Quality needs to be defined in terms of a particular framework of cost.

The national regulatory quality certification and international quality programmes like iso 9000 series lay down the broad quality parameters based on which companies maintain the export quality in the garment and apparel industry. Here some of main fabric properties that are taken into consideration for garment manufacturing for export basis:

  1. Overall look of the garment. 
  2. Right formation of the garment. 
  3. Feel and fall of the garment. 
  4. Physical properties. 
  5. Colour fastness of the garment. 
  6. Finishing properties 
  7. Presentation of the final produced garment.
