In the current garment industry, the lack of sewing threads is indispensable. Because sewing thread is an important accessory in bonding pieces to produce a quality finished garment. And an important thing for sewing thread is the quality, if the quality of the sewing thread is not met, it will cause us to have low-quality clothes that deteriorate quickly. So what is quality sewing thread? Is that the question you are asking? That is why this article has been born, I will tell you the requirements of sewing threads that are required to be considered a quality accessory.
1. What is sewing thread?
Sewing threads are flexible fibers, of equal small diameter, very malleable. Usually they will be processed on the outer surface by dyeing, oiling. They are used to link one or more pieces of fabric together through seams.
2. Types of sewing threads?
Currently, sewing threads are classified into two types:
+ Only from natural fibers such as cotton, wool, silk, ...
+ Only from chemical silk of artificial origin such as Vixco, PES, PA, PAN, ...
- Classification of sewing threads according to processing materials including: cotton, polyester cotton, linen yarn, PE, metal, nylon, rayon, silk, wool.
- Classification of sewing thread according to the structure of thread includes: core yarn, filament thread, single filament thread, multifilament thread
3. The nature of sewing thread?
- A quality sewing thread product includes properties such as thread strength, elasticity, torsional balance twist, thread evenness.
- First we will consider the durability of just include:
Tensile strength: they are determined similarly according to the strength of single and plied yarns on broken tractor.
+ Abrasion resistance: they are determined based on the abrasive cycle starting through the pinhole until destroyed.
+ And is done as follows: first one end of the thread being tested will be attached to the triple pair, and the other end will be suspended with a load of five creating tension. Then pass through the second needle hole while the second needle is attached to the quadruple to receive a shaking or walking movement with amplitude from 0 to 40mm. The number of shakes or movements will be adjusted from 10 to 40 times per minute.
+ Ring tensile strength is determined as follows: prepare a sample only for testing with a length of 1500mm. Next we will cut it in half to create two loops that hook together. Then place them between the two pairs of broken tractor, 10mm from the edge of the chuck and perform the pull.
- Next is sewing thread elasticity based on thread size, number of spun yarns, curl, ... elasticity from 3 to 8.5%.
- Next, the twist, the balance of torsion: the number of turns must be over 1cm and the twist must not be too large to avoid stiffening leading to spiral suction, stitch removal, stripping leading to thread breakage.
- In the end, the evenness of thread is considered based on thickness, tensile strength, elasticity and color, ... to avoid thread breakage at the place of the weakest point.
4. What are requirements for sewing threads?
- The first is the requirement for thread uniformity and slenderness. Because if the sewing thread is not identical in terms of slenderness as well as diameter. When sewing, if the thread is not the same, the tension will be affected, which will reduce the stitch accuracy.
- The second is the durability requirement: to be able to create quality clothes, it cannot be said about the strength of the thread. Since they are the place that binds the fabrics together, seams with the necessary strength will help the clothes last longer. Durability is shown by the least number of thread breaks during sewing.
- The third is the requirement of softness: if the sewing thread is soft, they will close the stitches together during sewing. Helps the product to move comfortably.
- The fourth is the requirement of elasticity: sewing thread that is elastic will help the product be more durable. In the case of a moderate force pulling, the elastomer will help the product not be deformed but return to its original shape.
- Fifth, the requirement for torsional balance: the sewing thread without torsion balance, when removed, they will have the phenomenon of thread breakage or when in the process of going through the needle hole, the edge of the needle blade has The thread can be twisted, resulting in stripped thread or thread breakage.
- Sixth is the requirement of cleanliness: if the thread is not mixed with impurities, it will be considered clean. If they are mixed with impurities, they will be the cause of thread breakage when sewn or uneven seams, causing loss of aesthetics.
- Seventh is the requirement for thread shrinkage: to avoid wrinkling together during sewing.
Finally, the requirement for color fastness: a quality accessory must have a color fastness appropriate to each fabric, the chemicals they encounter, when being washed, exposed to sunlight, the user's sweat remains evenly colored. Not fading as well as discolored on products and clothes
The above is general information about the requirements of the thread must have that I have searched for, referenced. To be able to present to you, now you can probably know a quality sewing thread, they can meet any requirements, right? Hopefully the article can bring a lot of new knowledge and experiences to you
