GEM Polyester Embroidery Thread is designed for all types of embroidery from sportswear to emblems. Innovated for ease of use, our thread substitutes other types of embroidery thread in use, such as rayon, without any difficulties.

Prewound Bobbins are bobbins that are sold ready to be used whereas self-wound bobbins refer to buying thread to wind manually before using.

There are two types of prewound bobbin: normal, which has a plastic core or is wound to the metal/aluminium bobbin, and coreless, which is a self-supporting structure that does not require a plastic core.

In terms of quality, prewound bobbins are much better than self-wound bobbins due to different winding methods and different material used. Moreover, prewound bobbins which are coreless, such as GEM Prewound Bobbin, offers even higher quality and greater length than normal prewound bobbins, which leads to a significant rise in productivity and embroidery quality.

A very normal misconception is that Prewound Bobbins cost more than winding bobbins by oneself. While this is true on a surface level, if you factor in all the details, you are in fact saving cost by using Prewound Bobbins.

This is especially true for GEM Prewound Bobbin, where we can provide up to double the length of Self-Wound Bobbins. In addition, by using our bobbins, you also eliminate the costs and wastage associated with manual winding, as well as improve productivity through exceptional length consistency.

All of this leads to a reduction in unseen costs and loss which in turn, optimizes your production and makes using Prewound Bobbins a cheaper and more efficient choice for embroidery under thread.

Yes. We are able to manufacture our GEM Polyester Felt with a roll width up to 170cm upon special orders.


The core superiority of our Polyester Twill Fabric when compared to others in the market lies in the quality and hardness. Our Polyester Twill Fabric is designed to be stiff, but with a natural feel, which makes embroidery patches stand out without having to interline thick layers of nonwoven fabric.


Using the right type of interlining is a very important factor in embroidery quality and garment comfort.

Tear Away Interlining – Used in works where the embroidery backing has to be completely torn off, such as in sportswear.

Hard Type Interlining – Used in works with soft and thin fabrics such as in enhancing the structure of patches and emblems.

Soft Type Interlining – Used to interline works where the fabric needs to have a substantial structure while still being relatively flexible.

Fusible Interlining – Used in works where the fabric to be enhanced needs to be stuck to the interlining, such as in the case for woven insoles.

Dot Fusible Interlining – Used in quality works where fabric fusing needs to be highly consistent.

Wax Paper – Used in addition to Tear Away Interlining to enhance the crispness of the embroidery design, especially when embroidering small texts.

Spunbond – Used in quality works where embroidery backing comfort and complete coverage of embroidery under thread is essential.

Woven Mercerized Interlining & Fusible Woven Mercerized Interlining – Used in making hems & seams of clothing, as well as replacing traditional embroidery hoops.

Polyester Woven Fabric – Used for embroidery works that need to be soldered on the edges.

The main advantage of using Wax Paper is that it enables crisper embroidery lines, which makes embroidering small texts sharper. Another secondary advantage is that due to the properties of the wax, it reduces electrostatic discharge caused by embroidery friction, which leads to reduced needle breakage.

Special Interlinings

Water soluble film, felt, and fabric, all serve the same purpose: to dissolve in water after embroidery. However, the application of each material varies depending on the temperature of the water used and the type of embroidery finishing desired.

At Rapos Group, we supply all three types of water soluble materials. Our GEM Acqua Film (water soluble film) is designed to easily dissolve at room temperature. This material is mostly used to eliminate embroidery stitches from sinking into the fabric, such as when embroidering towels.

GEM Acqua Fabric (water soluble fabric), on the other hand is a nonwoven fabric which is used more for lace embroidery. Different to GEM Acqua Film, this material dissolves at higher temperatures between 40°C and 90°C.

Lastly, GEM Acqua Felt (water soluble felt) is a special type of material used to produce 3D embroidery designs. This material can be dissolved between 20°C to 60°C.

An advantage of all our water soluble materials is that they contain no formaldehyde whatsoever, making them absolutely safe for garment manufacturing.

In a production line, speed without any compromise on quality is absolutely essential. For that reason, our GEM Acqua Film is able to be washed in a Jigger Washer and a Continuous Washer among other types of industrial washing systems.

During any form of washing, industrial and normal, GEM Acqua Film will completely dissolve in water, which means that the residue will not “re-stick” on other pieces of fabric or garment.

Yes. In addition to a hot plate, GEM Magic Film can also be used with an Elna Press Ironing Machine. The time required for this is approximately 30 seconds.
