In what cases is polyester hot melt wire easily damaged?
Polyester hot melt wire, as a functional fiber widely used in the textile and apparel industry, is favored for its unique low melting point and high-strength bonding performance. However, even this high-performance material is easily damaged in certain specific circumstances. The following are several situations in which polyester hot melt wire is easily damaged:

1. Improper storage conditions
The storage environment of polyester hot melt wire has an important impact on its performance. If the warehouse space is small and cannot be ventilated in time, or the storage method is improper, the polyester hot melt wire may become damp, moldy or contaminated, thus affecting its quality and service life

2. High temperature effect
A major feature of polyester hot melt wire is that it can quickly melt and bond to other materials at high temperatures. However, if the heating temperature is too high or the heating time is too long, it may cause the polyester hot melt wire to over-melt, affecting its physical properties such as strength and wear resistance. Studies have shown that heating temperature has a significant effect on the strength and elongation of blended yarns. As the heating temperature increases, the yarn breaking strength first increases and then decreases, and the breaking elongation gradually decreases as the temperature increases.

3. Physical wear
Although polyester hot melt yarn has high strength and wear resistance, it may still wear out during long-term use, especially in high friction or high pressure environments. For example, during the manufacturing process, polyester hot melt wires may gradually damage due to continuous friction with machine parts

4. Chemical corrosion
Polyester hot melt wires may be sensitive to certain chemicals, especially in environments containing corrosive chemicals, polyester hot melt wires may be chemically corroded, resulting in a decrease in performance

5. Microbial attack
In humid or unsanitary environments, polyester hot melt wires may be attacked by microorganisms, such as mold and bacteria, the growth of which may cause damage to the fiber structure and affect its bonding performance

6. Incorrect use
During the use of polyester hot melt wires, if they are used improperly, such as applying excessive tensile force or using them under inappropriate conditions, they may also cause damage

7. Ambient humidity
High humidity environments may cause polyester hot melt wires to absorb moisture and expand, affecting their structural stability, and long-term exposure to high humidity environments may reduce their strength and wear resistance

Conclusion
Under what circumstances polyester hot melt wires are prone to damage can help us better protect and use this material, extend its service life, and maintain its excellent performance. Proper storage, use, and maintenance are the key to ensuring that polyester hot melt wires remain in good condition for a long time.

Correct storage method for polyester thermal melt yarn

As a special textile material, the storage conditions of polyester thermal melt yarn have an important impact on its performance and service life. Here are some suggestions on the correct storage method of polyester thermal melt yarn:

1. Keep dry and ventilated
Polyester thermal melt yarn should be stored in a dry and well-ventilated environment. Excessive humidity may cause the fiber to absorb moisture and affect its performance. Especially in a hot and humid environment, polyester thermal melt yarn is more susceptible to microbial attack and oxidation and yellowing

2. Avoid direct sunlight
Long-term direct sunlight may cause polyester thermal melt yarn to photodegrade, affecting its strength and color. Therefore, polyester thermal melt yarn should be stored in a dark place and avoid direct exposure to sunlight

3. Reasonable stacking
Wrong stacking method may cause damage to polyester thermal melt yarn. Avoid stacking too high to prevent the bottom tow from being deformed or damaged due to excessive pressure

4. Temperature control
The storage environment temperature of polyester thermal melt yarn should be controlled within a certain range. Too high a temperature may cause thermal degradation of the fiber, while too low a temperature may affect its physical properties

5. Clean storage
Polyester hot melt yarn should be kept clean during storage to avoid contamination by dust and impurities. This not only maintains the purity of the fiber, but also prevents quality problems during subsequent processing

6. Prevent mechanical damage
During handling and storage, polyester hot melt yarn should be protected from mechanical damage such as hooking, abrasion, etc. This may affect the integrity of the fiber and subsequent use effects

7. Clear identification
Each batch of polyester hot melt yarn should be clearly identified, including production date, batch number, specifications and other information for easy tracking and management

8. First-in-first-out principle
When storing and retrieving polyester hot melt yarn, the first-in-first-out principle should be followed to ensure the freshness and performance of the material

Following the above storage method can effectively protect the quality of polyester hot melt yarn, extend its service life, and ensure its performance stability during subsequent processing and use. Correct storage is not only a protection of the material, but also a guarantee of production efficiency and product quality.
