Rubber technology for the textile industry

In the textile sector, every stage of the production process — from dyeing to finishing, from washing to shrinking — requires elastomer components capable of guaranteeing precision, strength, and operational continuity over time. For decades, A.Piovan has designed and manufactured custom rollers, sleeves, and coverings in rubber, silicone, and polyurethane for the specific needs of each machine and each fabric, from denim to knitwear, from viscose to shirting.

The choice of compound and hardness is never arbitrary: it directly affects squeezing efficiency, dyeing uniformity, resistance to chemical agents, and the service life of the component itself. This is why A.Piovan works alongside textile machine manufacturers and fabric producers with a technical, consultative approach, identifying the most suitable solution for each application in terms of performance, process speed, and the chemical aggressiveness of the working environment.

Typical applications and compounds

Squeezing rollers for padders

Matched hardness combinations (e.g. 96/97 Shore A) to maximize water extraction from the fabric entering and exiting the nip

Sanfor Rubber Blankets

Belts for shrinking denim and heavy fabrics, with high mechanical strength of the inner layer

Rollers for bleaching and mercerizing:

Compounds resistant to alkaline and oxidizing agents at high temperature (caustic soda, peracetic acid)

Rollers for indigo and rope dyeing

Black compounds, 65-75 Shore A, with excellent elastic recovery to ensure uniform dyeing on denim

Spreader sleeves for width guiding

Bottle-opener effect profiles for delicate fabrics, without leaving marks

Technical insight

In finishing padders, squeezing efficiency depends on the combination of hardness between the two paired rollers: a calibrated difference (for example, one harder roller and one slightly softer one) creates a barrier effect that extracts surface water at the entrance of the nip, while the pair of flexible rubbers penetrates the fabric structure to remove residual water, reducing the phenomenon of re-absorption at the exit.

Compounds for high squeezing: matched hardness combinations (e.g. 96-97 Shore A) designed to keep mechanical properties stable for years, reducing the frequency of regrinding
Microporous coverings for the sizing bath: regular, uniform application of sizing agent on the yarn, with long-term stability
Black compounds with high chemical resistance for impregnation, bleaching, and mercerizing: designed to withstand hot process conditions in the presence of oxidizing and alkaline products, where standard compounds degrade quickly
Compounds for dyeing with silicate-based dyes: specific chemical resistance for the most aggressive dyeing baths
Compounds for indigo and rope dyeing: hardness grades of 65-75 Shore A with fast elastic recovery, for uniform color application on denim
Sanfor system for shrinking: multilayer structure with greater mechanical strength on the inner face, for demanding working conditions and lower risk of abrasion or cracking
