Technical Characteristics of Textile Fibres: Keys to Specifying Contract Fabrics
07/01/2022
The technical characteristics of textile fibres determine their suitability for spinning and, ultimately, the quality and performance of the finished fabric. For professionals specifying contract fabrics for hotel interiors, care homes or communal spaces, understanding these properties is essential when choosing the right textile.
1. Length: the longer the fibre, the higher the yarn quality, with less twisting, less fibrillation and less tendency to pill. Natural fibres (staple) range from 1 mm to 350 mm, while chemical filaments can be produced in unlimited lengths.
2. Fineness or diameter: fibre quality is directly related to the length-to-thickness ratio. Finer fibres produce softer, more even yarns.
3. Natural shape: the tendency to crimp, thickness variation and cross-sectional geometry of each fibre influence the texture, lustre and final appearance of the fabric.
4. Elongation capacity: the ability of a fibre to stretch before breaking, which is decisive in upholstery fabrics subjected to mechanical stress.
5. Tensile strength: the force required to cause breakage through stretching. Fibres break more easily when wet than when dry — a relevant factor for industrial washing protocols.

Elasticity, conductivity and absorption: key properties for high-performance fabrics
6. Elasticity: the degree to which a fibre can elongate and still recover its original shape. High elasticity ensures that upholstery and curtain fabrics maintain their appearance after prolonged use.
7. Static conductivity: the tendency of the fibre to accumulate electrostatic energy, a critical factor during spinning and finishing. High static conductivity is inversely related to moisture absorption capacity.
8. Moisture absorption capacity: the fibre must remain within certain relative humidity values to be suitable for spinning and dyeing. This property also influences the end-user's perceived comfort.
9. Dyeing suitability: the fibre's affinity with dyes and chemical colouring agents determines the vibrancy, fastness and durability of the colour in the finished fabric.
In the contract sector, where fabric durability standards are highly demanding, these nine characteristics define the difference between a fabric that maintains its performance after thousands of use cycles and one that deteriorates prematurely.

Fibre blending as an optimisation strategy at Aznar Textil
In practice, fibre blending is the standard strategy for producing fabrics that combine the best properties of each material. The most noble fibres — such as silk or cashmere — are incorporated in calculated proportions to contribute hand feel and appearance, while technical fibres such as polyester provide the durability and abrasion resistance demanded by contract use.
As contract textile manufacturers in Spain, at Aznar Textil we apply this knowledge in the development of every collection. Our OEKO-TEX® Standard 100 and GRS (Global Recycled Standard) certified fabrics are the result of rigorous fibre selection, with ISO 9001 quality controls ensuring compliance with the abrasion ratings recommended for commercial upholstery.
