In the industry and agriculture today, in order to produce products such as cement bags, sugar bags, fertilizer bags, ... an extremely important material is indispensable. the sewing thread is the packaging itself. Although it is only a small thing, but without it, making products such as cement bags, sugar bags, fertilizer bags of all kinds ... that you are using is impossible without need. come. So what is the sewing thread that is so important and necessary. And it is possible to buy sewing threads from the most reputable sewing thread manufacturers. Please everyone read the article below.
Let's go to the article with the first question.
1. What is sewing thread?
Sewing thread is the type used only to connect the bags of product packaging together.They are small and even in diameter, they are often meticulously machined to achieve a certain smoothness to help them. can be through sewing needles, through bags or packaging easily. Helping your finished products in the packaging process are sure, not falling out, and also making the product more beautiful before being shipped to consumers.
2. What are the sewing thread characteristics?
- Sewing thread for packaging is the type of thread that has high flexibility, can be bent, straightened or any shape can be done easily.
- Depending on the type of sewing thread, they have many distinct colors with its own characteristics.
- With different types they have different sizes, such as big or small depending on the sewing product.
In each type of product, they all have different properties, so only sewing the packaging has what qualities we should follow below.
3. The nature of the sewing thread packaging?
- The first is the breaking strength of the sewing thread, depending on the size of the thread, the larger the thread, the better the breaking strength, in a simpler way, the larger the thread, the harder it is to break. the smaller it is, the easier it will break The breaking strength of the thread is usually evaluated according to the following three criteria: the first is absolute breaking strength, the second is the relative breaking strength, and the third is the loop breaking strength. .
- The second is the elasticity and elasticity of sewing thread, depending on the type of sewing thread when you apply a moderate amount of force on the thread to see how elongation of the sewing thread is. . Then, after being stretched, the length of the thread is constant, it has good elasticity. If it does not return to its original shape, the thread is soft and malleable.
- Third is the uniformity of sewing thread, the sewing thread for good packaging is the thread with the same diameter and the thread surface has a certain smoothness, no ruffles, no twists, no knots. , no humping.
- Fourth, the abrasion resistance of sewing thread, when bent, twisted or frictional on the sewing machine at high speed with various types of stresses and repeated deformation many times with high frequency will cause the yarn only reduced its features and durability.
- Fifth color fastness of the thread.
4. What kind of sewing thread are there?
According to the raw materials, sewing thread has all kinds of cotton thread, polyester thread, nylon thread, PE thread, rayon thread, PA thread.
Let's analyze each type of sewing thread:
+ Cotton thread is only relatively soft, the strength is not too high, less friction, very easy to sew.
+ Only pylyester is the type most commonly used today, because of its high strength, good color fastness, softness, high abrasion resistance, termite resistance, decay resistance, and wrinkle resistance Good elasticity, cheap price but affected by high temperature when sewing at too fast speed. Produced by inserting polymer plastic into small holes under high pressure, then solidifying as filament.
+ PE thread has high abrasion and durability, when used PE threads will create durable, strong and heat resistant seams.
+ Rayon thread is high heat resistance, non-elastic thread, good softness, produced by inserting cellulose acetate into small holes under high pressure, then solidifying as filament.
+ Only PA is the type that has only high durability and smallness, good abrasion resistance but is susceptible to aging under sunlight, good resistance to fire and cutting, unfavorable elongation properties.
+ Nylon thread is a type of nylon thread consisting of two main types, type 6 and type 6.6. This thread is unaffected when immersed in water, has good heat resistance up to 180 degrees C, more specifically type 6 melts at 225 degrees C, type 6.6 melts at 250 degrees C.
5. Note when selecting sewing thread for packaging?
On the market today, there are many different packaging designs, very rich and diverse as well as its materials. To be able to choose to buy products like that and with good quality you should pay attention to the strength of the thread and choose the right thread that you need to sew your product, do not choose the wrong or choose the wrong one because That will affect the durability of the product that you have made, making the product's quality not good or damaged quickly.
6. Where to buy sewing thread for packaging?
Being able to choose the type of sewing thread with quality and Sure, where the sewing thread manufacturing companies are, it must be a very difficult problem for you, to reduce that, I would like to introduce to you Nam Phat Import Export Investment Co., Ltd .
