This yarn is exceptional for its features of: What is mercerization for? Mercerization greatly improves the cotton yarn features increasing the value of yarn and differentiating the offer. Applications may vary from socks to underwear, from shirts to accessories, from sewing to embroidery. EXAMPLE  Softness  Dimensional Stability  Luster and Brightness  Confort

If cotton is dipped into a bath of a strong alkaline solution (caustic soda, lithium hydroxide, potassium hydroxide) the fibers will swell and shrinks. If the fibres are placed under tension during this process and then rinsed with water the alkali will be removed with a silk-like luster result. Alternatively, if the alkali is rinsed off when the fibre is in its shrunk state, the increase of luster may not be noticeable but the fibres will fix in that shrunk state, thus giving good elasticity to external stress.

The degree of swelling of the cellulose is the most important factor and it is related to the alkaline concentration.

All rights reserved. 7 The behaviour of the alkaline solution Anyway the process has some complications because the water content of the yarn before mercerization (usually around 40%) steadily dilutes the caustic soda, the concentration must be prevented through the steady addition of a corresponding high-concentration alkaline solution. Furthermore, to avoid a rise in temperature due to the dilution heat and the heat generation that accompanies the cellulose fibre absorption of the alkali, the alkaline solution must be cooled, thus allowing the preservation of a constant temperature. Poor caustic soda preparation units may not provide good and constant control over all those effects resulting in a low quality mercerization in terms of mercerization grade and of repeatability of batches.

Low quality machines in the process line may compromise the production quality or the production rate significantly.

All rights reserved. 9 HL-2000X mercerization system Top quality mercerized yarns through:  Customized process cycles and settings according to the features of the yarns (quality and counts) and to its final usage  Extremely precise control of yarn elongation (  0.1 mm)  High stretching force (up to 70 Tonns)  Continuous recycling of the alkaline solution to avoid dilution and over-heating  Reduced hanks handling by the operators (with ALS-2000X)  Batch production flexibility THE HANK MERCERIZATION SYSTEM based on our new Hanks Mercerizing Machine HL-2000X with the Automatic Loading System ALS-2000X

10 Copyright © Jaeggli Meccanotessile srl. All rights reserved. 10 Ancillary equipments EB-2000X Our Eco-Block for caustic soda preparation provides full control of the caustic soda parameters that affect mercerization: concentration, temperature, filtration continuously in real time (and not on batch). Dosing of the wetting agent is included. One Eco-Block can supply up to 2 HL- 2000X machines. HD-2000 Since constancy of hanks reeling size is a critical aspect for repeatibility of the process; our Hank Measuring Device can help in setting-up and maintaining the reeling machines For the best mercerization process control Jaeggli-Meccanotessile also produces the necessary ancillary equipments:
