In the modern clothing production process, the use of hot melt adhesive film has become a key technology and is widely used in the fields of stitching and laminating. The advantages of hot melt adhesive film are not only its good adhesion and washability, but also its role in simplifying the production process. Especially in the production of clothing pockets, hot melt adhesive film plays an indispensable role. Today we will explore in depth the types, characteristics and process flow of hot melt adhesive film for clothing pockets to help everyone better understand its importance in clothing production.
1. Types of hot melt adhesive film for clothing pockets
Clothing pockets are a basic component of clothing, which not only play a decorative role but also have practical functions. The production of clothing pockets often involves the lamination of multiple layers of fabrics, and hot melt adhesive film has become an ideal adhesive material. Among the many types of hot melt adhesive film, the types of film mainly used for clothing pockets include TPU (thermoplastic polyurethane) and PES (polyester hot melt adhesive film). Compared with the hot melt adhesive film for ordinary clothing, the selection range of hot melt adhesive film for pockets is narrower, mainly focusing on these materials.
Among them, TPU hot melt adhesive film is widely used because of its elasticity and adjustable melting point range. The melting point of this adhesive film can be selected from a range of as low as 40-50℃ and as high as 160℃ according to demand, which is suitable for lamination of different types of fabrics. Elasticity is also a major advantage of TPU adhesive film, especially under high melting point conditions, its elasticity is excellent, and it is suitable for clothing pockets that require high elasticity.
Compared with TPU adhesive film, the characteristic of PES hot melt adhesive film is that it has better water washing resistance, and its melting point is about 115℃, which belongs to medium and high temperature adhesive film. Although this type of adhesive film has no elasticity, it is often used in clothing with high durability requirements due to its excellent water washing resistance.
2. Characteristics of hot melt adhesive film for clothing pockets
When discussing hot melt adhesive film for clothing pockets, we must clarify its main characteristics: elasticity, melting point range and water washing resistance.
Elasticity and melting point range of TPU hot melt adhesive film
TPU hot melt adhesive film has an adjustable melting point, which makes it very adaptable and can meet the needs of different clothing designs. Generally, TPU hot melt adhesive films with low melting points have almost no elasticity, while those with high melting points have strong elasticity. Therefore, highly elastic TPU hot melt adhesive films are particularly suitable for those garment pockets that require elasticity, such as sportswear, clothing with elastic fabrics, etc.
Washability of PES hot melt adhesive films
In contrast, PES hot melt adhesive films pay more attention to washability. PES adhesive films are used more frequently on some garments that need to be washed many times. It can not only maintain good adhesion after washing, but also withstand high-temperature washing. However, the disadvantage of PES adhesive film is that it has no elasticity, so it is not suitable for use on fabrics that require elasticity.
Advantages of backing paper design
Most hot melt adhesive films for clothing pockets adopt a backing paper design because this design can improve the convenience of cutting and bonding. The backing paper adhesive film is simpler to cut, and the film can be cut accurately according to the shape of the pocket and prevent adhesion during operation. When using the hot adhesive film, workers can easily peel off the backing paper part of the hot melt adhesive glue film to expose the adhesive surface and align it with the pocket fabric for bonding. The design with backing paper not only improves production efficiency, but also ensures stronger bonding.
3. Application process of hot melt adhesive film for clothing pockets
The production process of clothing pockets is not complicated, but in order to ensure the quality of the finished pockets, it is crucial to choose the right hot melt adhesive film. The following is a typical operation process of hot melt adhesive film for clothing pockets:
Cutting of adhesive film
First, cut the TPU or PES hot melt adhesive film with backing paper into a shape that matches the shape of the pocket. Since there is a layer of backing paper on the surface of the adhesive film, the adhesive films will not stick to each other during the cutting process, which makes the cutting work easier and more precise.
First bonding
Align the backing paper side of the adhesive film with the fabric position to be bonded to the pocket to ensure the correct position. Then heat the other side of the backing paper with a heat press so that the adhesive surface of the adhesive film is firmly bonded to the fabric. This process can be completed with only a short heating time.
Tear off the backing paper
After the adhesive film is bonded to the fabric, wait for it to cool for a few seconds and tear off the backing paper from the adhesive film. This step is very important. After tearing off the backing paper, the other side of the adhesive film will be exposed, which is convenient for the next step.
Secondary bonding of pocket fabric
Overlap the prepared pocket fabric with the bonded fabric and heat it again through a heat press. This heating will not only firmly fix the pocket, but also make the bonding effect of the adhesive film more durable and stable.
Bonding completed
After secondary heating, the bonding of the clothing pocket and the clothing is completely completed. This process ensures that the pocket of different clothes will not fall off easily and has a long service life.
4. Advantages of hot melt adhesive film for clothing pockets
Compared with traditional sewing methods, using hot melt adhesive film to make pockets has the following advantages:
- Simplify the production process: The use of hot melt adhesive film can reduce the sewing process, save production time, and improve production efficiency.
- Increase aesthetics: Clothing pockets that made of hot melt adhesive film will not leave obvious stitching marks, making the clothes look more simple and fashionable.
- Improve durability: The hot melt adhesive film produced by Alster has strong adhesion, especially in terms of water resistance, and is suitable for clothing that needs to be washed frequently.
5. Conclusion
Through the introduction of from Alster, I believe that everyone has a deeper understanding of hot melt adhesive film for clothing pockets. Whether it is the elasticity advantage of TPU hot melt adhesive film or the washability of PES hot melt adhesive film, choosing the right adhesive film can greatly improve the quality and production efficiency of clothing pockets. In particular, hot melt adhesive film with backing paper design brings greater convenience to the production process. With the continuous advancement of clothing technology, hot melt adhesive film technology will play an important role in more fields.
