Technical information
on Régitex yarns
Yarn sizes, processes, fibres and definitions: everything you need before requesting a quote.
Technical resource
Here you will find the technical data on production: spinning processes, available structures, the fibre families we work with and a glossary of trade terms. Régitex has been spinning in Saint-Joseph-de-Beauce, Quebec, since 1998.
This page is for people who validate a specification before committing to development: purchasing, product management, engineering, compliance. Here you will find what you need to prepare a quote request, and the vocabulary to discuss it with the technical team.
The processes themselves are described in detail on the Expertise page.
Technical characteristics
What are the specifications of Régitex yarns?
Régitex works with two spinning processes and builds its colours from fibres that are already coloured, most of them solution-dyed. The table below lists the parameters a specifier checks first.
Spinning processes
Ring spinning (ring spun) and open-end spinning (open-end)
Structures
2 to 4 plies
Single yarns and plied yarns, assembled from 2 to 4 plies
Fibre families
Natural, artificial or synthetic, alone or in blends, recycled or not
| Colour | Already coloured fibres, most of them solution-dyed. Shades built by blending |
|---|---|
| Yarn sizes | Single yarns from 4 to 38 Ne (cotton count, cc), or about 15 to 147 tex, including 4 to 15 Ne in open-end spinning. Up to 40 Ne for plied yarns, usually in 2 to 4 plies |
| Twist | Not published: twist data is not meaningful to publish. Régitex sets the twist according to how the yarn will be used |
| Tolerances | Ring spinning and open-end spinning: twist ±5%, yarn size ±5%, evenness ±7%, measured to ASTM, AATCC and CATCC standards |
| Compliance with standards | Régitex yarns are not directly certified: certifications are usually granted to the fabrics and finished garments made by our customers. However, they can be designed to meet the requirements of many recognized industry standards, including NFPA, ASTM, ISO, OEKO-TEX, BNQ, CATCC, AATCC and EN |
| Minimum order quantity | 2,000 lb |
| Quote turnaround time | Within 24 business hours |
| Production site | Saint-Joseph-de-Beauce, Quebec, single plant |

Composition and materials
Which fibre families go into Régitex production?
Régitex makes its yarns from three fibre families, used alone or in blends. They differ in where the material comes from, and the choice depends on the performance your finished product needs.
Natural
Natural fibres come from plant or animal sources. They bring comfort next to the skin.
Artificial
Artificial fibres are made from a natural material that has been transformed.
Synthetic
Synthetic fibres are produced by chemical synthesis. Para-aramids and meta-aramids belong to this family: they withstand heat, cuts and abrasion, and serve the protection market.
Régitex works with a wide selection of recognized technical fibres, with no brand restriction: AKSA, Dri Release, Kermel, Lenzing, Nomex, Kevlar, Protex, Teijin Conex, Teijin Twaron, PBI, Pyrotex, Zylon, Kuralon and Arawin. The choice is driven by the performance your product needs, not by a supplier imposed on you.
The choice of material also affects the environmental footprint of your order: nearly 90% of an order’s greenhouse gas emissions come from the fibre itself (within 5 percentage points). This footprint is calculated order by order. See the Sustainability page.
Are recycled fibres a fourth family?
No. The word “recycled” indicates the source of the fibre, not what it is made of: a recycled aramid remains a synthetic fibre, a recycled cotton remains a natural fibre. Recycled material is of the same nature as the original fibre and can be used in a fibre blend without changing the nature of the blend.
At Régitex, recycled fibres are integrated depending on the application, from specialized suppliers. The proportion is set case by case, with you.
Is viscose a natural fibre?
No, and it is not synthetic either. Viscose is an artificial fibre: its raw material is natural, wood cellulose, but it is dissolved and then re-formed into filament by a chemical process. Modal and lyocell belong to the same family. The word “natural” here refers to the origin of the material, not to the process used to make the fibre.
Cotton and flax are natural, taken from the plant and spun without chemical reconstitution. Polyester and aramids are synthetic, produced by synthesis from petroleum derivatives.
Is flax a natural fibre?
Yes. Flax is a bast fibre: it comes from the stem of the plant, not from its seed like cotton. The bundles are freed from the stem by retting, a controlled decomposition that separates the fibre from the rest of the plant, then combed before spinning. Flax is longer and stiffer than cotton, which gives a less bulky yarn and a drier hand.
What is an aramid fibre?
An aramid fibre is an aromatic polyamide, a synthetic fibre whose molecular structure gives it high resistance to heat and to breaking. The two families differ in how this structure is arranged. Para-aramids are oriented along the polymer axis, which makes them very resistant to tensile stress and cuts. Meta-aramids are oriented more irregularly, which gives them better thermal stability and better flexibility.
Both go into protective yarns, alone or in blends, and the choice depends on the risk to cover rather than on overall performance.
Short fibre or filament: why it changes the yarn. A short fibre, called discontinuous or staple, measures a few centimetres and has to be spun, that is, drawn out and twisted to increase cohesion between the fibres. A filament is continuous: a filament yarn usually does not need twisting; the filaments only need to be held together to keep the yarn cohesive. Régitex spins staple fibres: this is what gives the yarn its bulk and its hand, and it is also why the length of the fibres used governs the performance of the outgoing product.
Technical information
Technical yarn glossary
Twelve terms that come up in conversations with your teams, defined in one or two sentences.
Yarn manufacturer
A yarn manufacturer turns fibres into yarns for weaving and knitting. Régitex has practised this trade in Saint-Joseph-de-Beauce, Quebec, since 1998.
Ring spinning (ring spun)
Ring spinning draws out the roving, then twists it around a ring, in one continuous motion. The fibres are held tightly against one another along the whole length of the strand.
Open-end spinning (open-end)
Open-end spinning separates the fibres, conveys them to a rotor, then brings them together and twists them. The strand forms continuously, without going through the roving stage.
Roving
Roving is the thinned, lightly twisted band of fibre that comes before spinning. It is strong enough to be handled, but it is not yet a yarn.
Twist
Twist is the number of turns given to the material per unit of length. It ensures cohesion between the fibres and largely determines the strength and hand of the finished product.
Single yarn
A single yarn comes off the spinning frame as one strand, with no later assembly.
Plied yarn
A plied yarn is made by assembling and twisting several single yarns, called plies, together. Régitex assembles 2 to 4 of them.
Tenacity
Tenacity measures the force a yarn can withstand before breaking, relative to its size. It is one of the parameters that tell you whether the material will withstand the mechanical work imposed by weaving or knitting.
Yarn size (Ne, cc, count)
Yarn size describes how coarse or fine a yarn is. Here it is counted in Ne (cotton count, cc), an indirect numbering system: the higher the number, the finer the strand. The count is the number of 840-yard hanks it takes to make one pound of yarn.
Hand
Hand is the feel of the textile: what the material lets you sense under your fingers.
Colour blending
Régitex usually does not dye its fibres: it builds the shade by blending fibres that are already dyed, in the desired proportions, before spinning. Colour is part of the material from the start, rather than applied afterwards.
Winding
Winding refers to how the material is laid onto the cone. A poorly wound cone causes machine stoppages and lost productivity at the weaving or knitting company.
