Linen thread is the historical thread of the Fil Au Chinois brand. When the company was founded by Philibert Vrai in 1847, sewing machines did not exist and linen thread made up the bulk of their sales. This explains the existance of different presentations, either on classic spools, capsules or even star cards, each with a different length of thread. When Toulemonde took over Fil Au Chinois in 2007, they were keen to conserve these different presentation, which constitute part of their historical heritage.
This Fil Au Chinois Special Cordonnerie thread is the same as the Cordonnet thread, but with a larger, professional presentation. It is a polyester thread, which has the advantage of being extremely resistant to humidity. It is perfect for leathers which will be exposed to the climates, such as shoes or saddles. It is also perfect for jewellery making, as it is solid and dries rapidly, which is not the case for cotton or linen threads. This thread has been waxed by passing through a bath of starch and beeswax, making it more resistant with a certain stiffness which makes it easier to use.
The Fil Au Chinois waxed cable linen is a luxury thread for high-quality leather work. As indicated in the name, this thread is cabled, signifying that the threads have been twisted a first time, and then these threads are assembled and twisted a second time. The term "câblé", or corded, signifies this double twist. This obviously increases greatly the solidity of the thread, but also makes it more rounded, particulary adaptable for leather work. We have five thicknesses of lin câblé: the N°332 (0.77mm diametre), the N°432 (0.63mm diametre), N°532 (0.57mm diametre), N°632 (0.51mm diametre), and the N°832 (0.43mm diamètre).
The Fil Au Chinois Special Maroquinerie thread is made of high-resistance polyester which is coated with cotton fibre. It is then assembled and twisted in three strands. The thread is then tinted and waxed. A waxed thread means that it has passed through a starch bath to which bees wax has been added. It is then brushed with horse hair and stretched. These operations ensure a thread which is smooth and resistant for the most rigid stitches.
