Introduction:
The strength properties of apparels have been considered the most obvious indication of the service life of apparel. The strength of fabric or garment indicates its ability to resist mechanical damage due to stress of normal wear and laundering. This article has shown some key points which assures about the apparel strength, hope it will be very effective for all.
Properties of Apparel Strength:
There are various key properties of apparel strength which are pointed out in the following:
- Fabric strength,
- Seam strength,
- Resistance to yarn slippage.
All the above apparel strength properties have explained in the below:
1. Fabric strength:
Fabric strength can be divided into three different areas i.e. resistance to tensile force, resistance to tearing force and resistance to bursting force. In the case of woven fabric resistance to tensile force and tearing force are measured but in case of knitted fabric resistance to bursting force is measured to assess the fabric strength.
2. Seam strength:
Seam failure of a garment can happen due to the failure of the sewing thread leaving the fabric intact or fabric rupture leaving the seam intact or both breaking at a time. Seam strength is tested in almost the same manner as fabric breaking and bursting strength. The strength of a seam or stitching should be equal to or slightly less than the fabric strength. The elements which have great impact on the strength of a seam or stitching are:
- Stitch type,
- Thread strength,
- Stitch per inch (SPI),
- Thread tension,
- Seam type,
- Seam efficiency of the fabric.
3. Resistance to yarn slippage:
Seam failure may also occur due to displacement of yarns present in the cut area of fabric after seam line or stitch line due to stress on seam or joint of the apparel.
