The complexity of textile fibers production
Synthetic fibers are obtained through chemical processes. Proper tools are mandatory for this industry type.
In Italy, production and machineries of Textile branch count revenues higher than 20 million euros (Source: Euler Hermes). These industries are a real flagship for Italian Manufacture nor a worldwide excellence. Textile fibers’ manufacturing is tied up to ancient traditions of our country. This activity mostly developed in Northern Italy: Milan’, Bergamo’ and upper Vicenza’s area. Involved companies, mainly of small and medium size, continuously make investments in new technologies and take care of the whole production chain. This Italian branch is made up of 300 active companies with more than 12.000 workers (Source ACIMIT).
Textile fibers classificationArtificial and synthetic textile fibers represent the 60% of fibers that are used around the world.
A fiber can be considered artificial when a natural raw-material is processed with chemical substances. This fiber type is obtained by renewable raw materials that are assimilable to natural fibers. Artificial fibers are Raion, Leacril and Acetates.
A fiber can be considered syntheticwhen the raw material is not natural but artificially obtained by men. It originates from polymers (organic compound whose molecules are made of many similar structure units) through chemical synthesis. This chemical process is named polymerization and can operate in two different ways: addition or polycondensation.
Polyester, polyamide, acrylic and carbon fibers are synthetic fibers. 40% of textile fibers, that are used around the world, are natural and have a vegetal origin like cotton, linen, hemp and jute. Each fiber is characterized by excellent properties according to the specific use but very poor for others:
- Morphological: geometry, brightness, hand;
- Chemical: material stability with chemical agents or photoreaction resistance;
- Mechanical: reaction to heat, electricity or mechanic;
- Physiological: allergenic, heat or cool perception, resistance to bacteria or mold.
Centrifugal pumps for textile fibers productionPlants dedicated to textile fibers production are very big and work 24hours. They foresee the use of traditional polymerization technologies to transform the polymer in fiber (wad or non-stop wire shape). For this application type, 3 centrifugal pumps of CDR Pompe are recommended:
- UTS: single-stage centrifugal pumps with high efficiency magnetic drive capability. They are suitable for 24h applications especially for thermoregulation processes that are proper of synthetic textile fibers production
- ETS: magnetic drive centrifugal pumps suitable for any low-duty application where stainless steel pumps are specifically required.
- XTS: magnetic drive stainless steel centrifugal pumps destined to liquids with suspended solids. They ensure service conditions, safety and reliability with basic chemical processes.
