From the Sector

Double the production rate, with lower energy consumption per kilogram of fiber material – that might sound like a contradiction, but the new Trützschler pre-cleaner CL-X makes it possible. It gently and reliably removes coarse contaminants like leaf debris, stalks or seeds from cotton with minimum loss of good fibers. The pre-cleaner CL-X provides more efficiency and lays the foundation for a high-quality end-product before the cotton is further processed in mixers and fine cleaners.

CL-X features at one glance

• Continuous production of 1,600 kilograms per hour for present blow room configuration.
• 30% energy saving compared to the current benchmark.
• Integrated WASTECONTROL for automatic adjustment recommendation of waste excretion to avoid unnecessary fiber loss.
• 2.60 m long cleaning section.
• New and improved grid geometry for better separation and gentle tuft treatment.
• Material draft due to 10 % higher speed of second opening roller for reliable and consistent fiber transport.
• Optimal cleaning level and minimal fiber loss due to individual and stepless grid adjustment for each opening roller by motor.
• Gentle tuft treatment with adjustable opening roller speed.
• Synchronized lot management (automatic lot change for up to three lots).
• Connection possibility for a waste box (for waste analysis).
• Lower cost of ownership.

• Innovative Textile Processes

Innovations are welcome. Based on innovations, many changes in textile processing are leading to more efficiency in process workflows. At the International Cotton Conference in Bremen on Wednesday, March 21st, Session IV Textile Processing, which takes place from 4:00 pm to 6:00 pm, is dedicated to this subject area and attractive examples.

Sustainable
Michael Tuschak, Mayer & Cie., Germany, informs about the 3-in-1 concept of Spinitsystems. Spinning, cleaning and knitting are all combined in one machine. This enables the production process of high-quality single jersey knitwear to be shortened significantly, which saves energy costs and reduces CO2 emissions.

Indigo.
An old dye returns to glory. Dr. Dean Etheridge of Texas Tech University, USA, talks about a new, innovative indigo dyeing process for cotton yarns using foam. This saves large amounts of water and is now increasingly being used by major brands in jeans production.

Efficient.
Amin Leder, Trützschler GmbH & Co. KG, Germany, presents a technique in which the stretching process for rotor yarn production does not take place in a separate machine, but is integrated into the carding. This makes it possible to efficiently process even cotton with a higher waste content.

Overview.
Harald Schwippel, from Rieter, Switzerland, summarises all four major spinning technologies for cotton – ring spinning, compact spinning, rotor spinning and air-jet spinning. His talk provides an overview of the possibilities that each of these processes currently offers for the manufacture of different yarns and the most efficient options for different applications.

More to know
In the run-up to the International Cotton Conference, the Fibre Institute Bremen and the Cotton Exchange are organising a specific seminar for spinning mills on Tuesday, dealing with the efficient handling of contaminants in cotton, from elimination in production to removal in winding. On Friday morning, Expert Session IX deals with the exchange of the latest research results, e.g. in the field of ginning in relation to cotton quality, or the important issue of checking the traceability of GMO-free cotton.
