In garment manufacturing people usually pay a lot of attention to the quality of the fabric. They check the fabric to see how strong it is, what color it is, how heavy it is and how much it shrinks.. There is one small thing that often gets less attention than it should. That is the sewing thread used in garment manufacturing.
Many people think that thread is only used to sew fabric pieces.. In reality thread (meta-aramid sewing thread) plays a very important role in the quality of the final garment. Thread is what holds the garment together. It can affect how the garment looks and feels.
One problematic issue is thread shrinkage. Thread shrinkage makes the thread reduces in size post exposure to heat, moisture, washing, etc. This can lead to seams that pucker or become distorted.
Incase the thread shrinks post garment wash or finish, it adversely impacts the way the garment looks and performs. This can lead to customers complaining about the quality of the garment returning it. The manufacturer having to spend more money to fix the problem. That is why understanding thread shrinkage is important for every apparel manufacturer.
What is Thread Shrinkage?
In thread shrinkage thread to become smaller after exposure to heat, moisture, washing or finishing processes. Like fabric can shrink thread can also shrink. The amount of shrinkage depends on things like the material the thread is made of how it is made how it is washed and what temperature it is exposed to.
Some threads shrink little while others may shrink more under certain conditions. Thread shrinkage adversely impacts the quality of the garment.
Why Thread Shrinkage Matters
A garment may look perfect when it leaves the factory. The seams may look smooth. The stitching may look neat.. After washing the thread could shrink while the fabric may not leading to defects like like puckering or distortion. The garment may not look as good as it did before. Customers may notice this right away.
Thread shrinkage can also cause seam puckering, which’s when the seam area becomes wrinkled or gathered. This can make the garment look poor even if it is a high-quality garment. Customers may think that this is a manufacturing defect.
Thread shrinkage can also affect the way the garment fits. If the thread shrinks significantly certain areas of the garment may become tighter. This can change the way the garment fits and customers may not be happy with it.
Thread shrinkage can also lead to customer complaints. Customers expect garments to look good after they are washed times. If the seams turns puckered or distorted post a few washes customers may complain. Top complains reported are wrinkled seams, distorted stitching and uneven garment appearance.
Causes of Thread Shrinkage
There are things that can cause thread shrinkage. The material the thread is made of is one factor. Different thread materials behave differently. Some are more prone to shrinkage than others. Polyester threads are generally known for having shrinkage than some other materials.
High washing temperatures can also cause thread shrinkage. If garments are washed in water they are more likely to experience shrinkage-related issues. Garment finishing processes can also affect thread dimensions. If the thread is not evaluated beforehand problems may appear after finishing.
Incorrect thread selection can also cause thread shrinkage. Sometimes manufacturers focus mainly on thread strength and color. They may overlook shrinkage performance. Choosing the thread for a particular application can create quality issues later.
How to Control Thread Shrinkage
The good news is that thread shrinkage can be managed with planning and testing. The first step is to choose threads with dimensional stability. Many modern sewing threads are designed to maintain their size after washing and finishing.
Testing the thread before bulk production is also important. Manufacturers should evaluate thread performance under garment conditions. This can help identify shrinkage problems before large-scale production begins.
It is also important to match the thread with the fabric. If the fabric and thread shrink differently seam problems may occur. Compatibility testing can help ensure garment performance.
Observing finishing conditions is paramount. Too much heat or aggressive treatment can increase shrinkage. Monitoring process parameters can help maintain quality.
Working with suppliers is also important. Thread quality can vary between suppliers and choosing suppliers can help ensure consistent performance.
Benefits of Controlling Thread Shrinkage
Controlling thread shrinkage offers advantages. These include garment appearance, reduced seam puckering, improved customer satisfaction, consistent garment quality, fewer product returns, lower rework costs and better brand reputation.
By selecting recycled sewing thread conducting proper testing matching thread with fabric and controlling finishing processes apparel manufacturers can reduce shrinkage-related problems and deliver better quality garments. Thread shrinkage may seem like an issue but its impact on garment quality can be significant. It can affect seam appearance, garment fit, customer satisfaction and overall product performance. Ignoring thread shrinkage may lead to defects that become visible after washing or finishing.
In apparel manufacturing paying attention to thread shrinkage is an important step, towards producing products that customers can trust and enjoy using. Apparel manufacturers should take thread shrinkage seriously. Implement measures to control it to produce high-quality garments that meet customer expectations.
