Air quality and quantity are both necessary for quality textile
by Imtiaz Rastgar.
Millions of miles of fabric are produced every year using
compressed air driven spinning machines and air jet looms.
Ensuring a quality stream of compressed air is essential in
minimizing fabric staining and production loss. With increasing
demand, textile manufacturers must select an efficient and
cost-effective solution that provides a quick return on
Producing beautiful fabrics, with the most
sophisticated colors and patterns is an art. Fashion designers
entrust their creations only to weavers or spinners who are able
to deliver the highest quality. That’s why textile producers
consciously choose 100% oil-free compressed air. Because quality
and productivity are an absolute priority.
Compressed air is blown through fine
nozzles to transport the weft. Oil in the air blocks the
nozzles, leading to production stoppages and costly nozzle
replacements. Fabric staining will also result, causing product
The exhaust air from the nozzles blows over
the air-jet weaving machines. Any oil present deposits on the
reeds. It attracts dust and fibers causing the reeds to stick
together and break. Resulting production losses and reed
replacements that are quite expensive.
Cotton is spun into yarn using compressed
air through fine nozzles. Oil in compressed air will lead to
nozzle clogging. It will also stain the yarn, which is in direct
contact with the compressed air. Expensive nozzle replacements,
production losses and product rejections will result.
The production of man-made raw materials,
for use in textiles, also uses compressed air. One of the
applications is the pneumatic transport of PVC, PTA or DMT
chips. Oil contamination can cause substandard products besides
being a fire hazard. Oil may also damage controls and
instrumentation components, resulting in breakdowns.
In this process, the yarn is intermingled
using a jet of air through a nozzle. Blockage due to oil will
cause uneven intermingling and destroy the yarn. Staining of the
yarn will also result.
In many applications, such as yarn
texturizing or textile weaving high volumes of compressed air
come in direct contact with the manufactured fabrics. To help
maintain high-quality standards, CompAir compressors provide ISO
8573-1 Class 0 oil-free air and show minimal variation at
extreme flow demands.
In addition to properly selected equipment,
delivery quality can be continuously monitored through
instruments indicating the quantity of oil, dust and moisture in
Oil in Compressed Air will lead to quality
problems and steps must be taken in the selection of air
compressors as well as maintenance of filtration equipment for
delivery of 100% oil-free air. Addition of these instruments to
air transmission lines can lead to control over air quality. For
