PES Copolyester Hot-Melt Adhesive in Garment Interlining Applications
In modern garment manufacturing, interlining—often called the “skeleton” or “inner structure” of a garment—plays a key role in maintaining shape, improving hand feel, and ensuring wash durability.
Traditional interlinings were made from cotton or viscose nonwoven fabrics bonded by mechanical or water-based adhesives. However, as fashion moves toward lighter structures and faster production, fusible interlinings using hot-melt adhesives have become mainstream.
Among them, PES (copolyester) hot-melt adhesive powders or webs have gained wide attention due to their outstanding performance and versatility in apparel applications.
Key Advantages
-
Low melting temperature – For example, certain PES copolyester hot melts feature melting points around 105–118 °C, with bonding temperatures typically 130–150 °C.
This makes them suitable for temperature-sensitive fabrics such as polyester–cotton blends, synthetic fibers, or printed textiles, reducing heat damage.
-
Excellent wash and dry-clean durability – Designed for garment interlining, these adhesives maintain bonding strength after multiple washing, dry-cleaning, and steam pressing cycles.
-
Lightweight, soft hand feel, and stable structure – PES adhesives enable thin, flexible interlinings that provide firm shape retention without adding stiffness or weight.
-
Compatibility with modern coating methods – They can be applied by dot printing, powder scattering, or mesh transfer, supporting efficient and precise mass production.
Application Considerations
-
Although PES adhesives melt at relatively low temperatures, the bonding temperature and dwell time must match fabric heat resistance to avoid deformation or heat marks.
-
Powder size, flowability, and coating method should correspond to the interlining substrate (woven, knitted, or nonwoven) and the equipment used.
-
After lamination, washing and shrinkage tests are recommended to verify bond stability and dimensional retention.
-
Increasingly, brands require eco-friendly and certified materials—for instance, OEKO-TEX® Standard 100 compliance, solvent-free formulations, and non-migrating grades.
Future Trends
With growing demand for lightweight, functional, and sustainable garments, PES copolyester hot-melt adhesives are expected to play an even larger role in interlining materials.
Future developments include:
-
Wider coating widths for efficiency,
-
Ultralight and soft-touch interlinings,
-
Low-odor and low-VOC formulations,
-
Use of recycled polyester raw materials for circular textile production.
For apparel manufacturers and suppliers, PES-based hot-melt adhesives represent an upgrading path for next-generation interlining solutions, combining performance, efficiency, and sustainability.
