Some people may not be unfamiliar with hot melt wire. As a textile material often used in our daily life, in addition to the two hot melt wire products of polyester and nylon that we all know, there are still many people who do not understand their respective advantages and disadvantages, specifications, prices, future development trends, etc. Today, I will systematically introduce this new type of textile material to you.
Take you to learn about hot melt wire in detail
1: Uses
At present, hot melt wire is widely used in outdoor sports shoe uppers, casual shoe uppers, sofa fabrics, curtain screens, carbon fiber cloth shaping, chenille yarn, Bondi line, high-end suit lining, lace and glove lock yarn, etc. It is a high-tech product with huge market prospects.
2: Function is advantage
When the temperature is higher than the melting point of hot melt wire, hot melt wire gradually melts. At this temperature, other conventional fibers remain unchanged and are bonded together by hot melt wire. Therefore, hot melt wire can replace chemical adhesives such as glue, avoid the pollution of volatiles and powder layers, and is environmentally friendly and non-toxic; at the same time, it saves process flow and reduces downstream production costs.
3: How to store and stack
Place it in a cool place that is conducive to ventilation and fire prevention. It should not be too humid. At the same time, it should be placed in an orderly manner. It should not be piled up randomly. On the one hand, it is easy to confuse. On the other hand, if it is placed randomly, it is not convenient to take it when it is used.
4: How to identify polyester hot melt yarn
1. Look at the glossiness: it has good glossiness.
2. Look at the price: general textiles are much more expensive. Cheap ones must not be polyester hot melt yarn or the quality itself is unqualified.
3. Touch feeling: it feels soft and smooth, the lines are tight and compact, and it feels a bit “cool”.
4. Water absorption: it has good water absorption and breathability. And polyester is not easy to fade.
5. Burning distinction: between 85℃ and 180℃, the hot melt yarn will dissolve and deform first. From the burning appearance, it is easy to have holes when encountering sparks.
6. Elasticity: its elasticity is close to wool, it bounces loose and soft, and it can restore itself to its original state under small elasticity conditions. It has good deformation resistance.
Five: Common specifications and corresponding prices
1. Nylon series: specifications: 30D, 40D, 70D; price: 50 to 80 yuan/kg.
2. Polyester series: specifications: 60D, 100D, 150D; price: 20 to 30 yuan/kg.
3. 3D upper: specifications: 50D, 75D, 100D, 150D; price: 60 to 90 yuan/kg.
Six: How to clean
1. The mesh part of the shoe can be cleaned with clean water, but the fur part of the upper should be wiped with a wet towel or cleaned with a special fur cleaning agent, which can effectively prevent the fur from wrinkling and deformation.
2. As for the edge of the shoe, you can squeeze toothpaste on its surface and scrub it repeatedly, and finally wash it with clean water.
3. If the shoe is dirty, you can use some baking soda and soak it in clean water for a period of time to easily clean the internal dirt and debris.
4. If there are organic substances such as oil stains, you can add some alcohol to clean them.
5. After cleaning, place it in a cool and ventilated place to dry, and avoid direct sunlight.
