Properties Of Sewing Thread
Parameters To Be Considered Of Sewing Thread or Embroidery Thread:The different parameters of sewing thread are now discussed below....
Tensile Strength: The minimum load required to break the thread is known as tensile strength of that thread.It is denoted by gm, kg or lb and may very depending on temperature, humidity, applied force, rate of return and length of thread.
Tenacity: The ratio of tensile strength and count or thickness of that thread is known as tenacity.It is denoted by gm per denier or gm per tex.Formula of tenacity: Tensile Strength/Count or Thickness.
Loop Strength: Sewing thread has minimum strength in its loop position and the minimum load required to break the loop is known as loop strength.
Loop Strength Ratio: The ratio of thread tenacity and loop strength of that thread is known as loop strength ratio.The maximum value of loop strength ratio may be 2.So loop strength ratio = (Tenacity/Loop Strength)=2 .
Elongation At Break: It is extension of thread at breaking point.This is expressed in percentage.Elongation of break is=(extension/original length)*100% .
Minimum Loop Strength: The loop strength is weaker loop is known as minimum loop strength.It is used to determine the performance of a thread in the stitch.
Elasticity: It is the property by virtue of which the thread returns back to its original position when deforming force is released.When the thread do not back to its original position after extension is called plastic.When the thread back to its original position after extension is called elastic.
Shrinkage: The dimensional change of thread after washing with water or heat is called shrinkage.It is expressed as %. For shrinkage of thread, seam pucker is occurred.
Abrasion Resistance: It is the frictional resistance of one thread to another thread.It is most important to determine the sewing performance of threads.
Color Resistance: The resistance of a thread to change in any of its color characteristics to transfer of its colorant to adjacent materials or both as results of the exposure of the thread to any environment that might be encountered during the processing , testing , storage or use of thread.
Twist: A thread with too little twist may fray and break one with too much can cause snarling, looping and knotting.
Ply Security: This is a thread's ability to stay together during the sewing process.The most common type of thread break is caused by a loss of ply security.If the piles open op during the sewing process they are much more susceptible to breaking.
Uniformity: Imperfections or defects in thread are thick and thin places that can cause sewing problems.The most common imperfections are-knots, slubs, neps,dropped ply,dropped filament and singles kinks obviously the fewer the better.
