The humble sewing machine for example is a design that dates all the way back to 1846 when the patent for a sewing machine was first filed. But surely with modern technology, specifically in ultrasonic welding, we can replace the old sewing machine for the very advanced ultrasonic method? The short answer is – sometimes!
Ultrasonic welding for garment manufacture is a state of the art method of garment bonding that is seeing real growth in specialist applications. Especially in waterproof seams of outdoor clothing and high performance sportswear that require very flat seams to prevent restriction of movement. Yet for some applications, it will simply never replace the current traditional sewing machine.
A traditional sewing machine punches holes into a fabric, increasing its risk of material failure. The needle punch holes of a sewing machine can damage the super fine knitted material of a fabric and make waterproof rainwear garments vulnerable to water penetration. The exact opposite of what that products primary goal is to prevent. Traditional sewing seams also add weight, thickness and restriction of movement. None of which are desirable in advanced sportswear clothing.
In all these situations, the use of ultrasonic sewing is a preferred choice. However, while the advantages of ultrasonic sewing are well known, there are some materials that are best left with traditional sewing.
There are two main restrictions to ultrasonic sewing.
But while these may be draw backs for some sectors within the garment manufacturing industry, the list of possible applications for ultrasonic welding is very long; and as technology, fabric science and consumer demands evolve, we expect to see growth in the demand for ultrasonic sewing machines in more traditional applications including:
