Why is Woven Plain/Twill Interlining more abrasion and wrinkle resistant than nonwovens?

1. Influence of fabric structure
The most notable feature of Woven Plain/Twill Interlining is its unique fabric structure. This structure is formed by weaving the longitudinal warp yarns and the transverse weft yarns on a loom to form a stable interlaced pattern. This structure gives the fabric strong mechanical strength and stability, making it particularly good at abrasion resistance and wrinkle resistance.

Abrasion resistance: The warp and weft interlaced structure of the fabric makes Woven Interlining have excellent abrasion resistance. The warp and weft yarns are intertwined during the weaving process to form a strong structure, making the fabric surface more difficult to be affected by friction. In contrast, nonwoven fabrics are usually formed by fibers through heat pressing, chemical bonding, etc. The connection between the fibers is not as tight as that of fabrics, resulting in poor wear resistance. Long-term use and friction can easily cause damage to the surface of nonwoven fabrics, and even cause wear and tear, hair loss, etc.

Wrinkle resistance: The weaving process of Woven Plain/Twill Interlining makes it have strong wrinkle resistance. Because of its stable structure and tight connection between warp and weft yarns, the fabric is not easily deformed or wrinkled by external forces. Even with frequent wearing and washing, Woven Interlining retains its shape. In contrast, non-woven fabrics are easily pulled and compressed by the outside world due to their loose fiber connections, which leads to wrinkles. Especially in humid environments, their wrinkle resistance is poor.

2. The role of hot melt adhesive coating
Woven Plain/Twill Interlining is usually treated with hot melt adhesive coating, which is a technology that bonds the interlining to the garment fabric through a hot glue layer. The treatment of hot melt adhesive coating not only improves the fixation of the fabric, but also further enhances the wear resistance and wrinkle resistance of the fabric.

Improved wear resistance: The hot melt adhesive coating provides an additional layer of protection for the fabric, making the fabric surface smoother and reducing friction resistance when in contact with external objects. This protective layer can effectively reduce the damage caused by friction and extend the service life of the fabric. Non-woven fabrics usually do not have similar adhesive layer protection, their surface is relatively rough, and they are easily damaged by long-term friction.

Improved wrinkle resistance: Hot melt adhesive coating not only improves fabric stability, but also helps reduce wrinkling of the fabric. The adhesive layer can firmly fix the fabric to the outer fabric, preventing the fabric from stretching and causing unnecessary wrinkles during wearing or washing. However, due to the loose structure of non-woven fabrics, they lack this fixing effect and are prone to form permanent wrinkles during use.

3. Fabric stability and shape retention
Woven Plain/Twill Interlining can maintain a stable shape for a longer period of time due to the stability of its fabric structure. In interlining applications, the shape of the fabric is crucial to define and finish the garment. The fabric surface is not easily deformed and wrinkled, making Woven Interlining a commonly used material in high-end clothing manufacturing, especially in areas that require additional support and shaping, such as suit collars, cuffs, trouser waists, etc.

4. Disadvantages of nonwoven fabrics
Compared with Woven Plain/Twill Interlining, nonwoven fabrics have obvious disadvantages in abrasion resistance and wrinkle resistance. The fibers of nonwoven fabrics are loosely connected and lack the tight structure of woven fabrics, making them prone to wear, tear or shedding under long-term use and friction. In addition, nonwoven fabrics have poor wrinkle resistance and are easily prone to irreversible wrinkles due to external pressure or moisture.
