Oligomer & the importance of Oligomer remover-------
Oligomer is a smaller chain length of polyester made up of two or more molecules of basic ethylene terephthlate i.e. dimer or trimer, produced as a side reaction during the manufacture of polyester. The Oligoester because of its smaller chain length is in the form of a fine powder which is entrapped is basic polymer and migrates to the surface during high temperature polyester dyeing.
Higher the depth more is the displacement of Oligomer to the fibre surface. Typically polyester fibres contain between 1.5-3.5% by mass of low molecular esters, the principal oligomer being cyclic tris (ethylene terephthalate) with smaller quantities of dimer, pentamer & other compounds. Approximately 0.1 % to 1.0 % of Oligomer is produced as a side reaction in the manufacture of basic polyester.

ABSTRACT: Natural dyes are those dyes obtained from natural sources. The majority of natural dyes are usually collected from roots, berries, bark, leaves, wood, fungi and lichens. Usually in ancient days people have dyed their textiles by using locally available materials. Cold extraction for crude dyes extraction from Cucurbita pepo leaves. Theextract obtained quantitatively from cold extraction method was 6.81g and 2.27g respectively from 100g and 50g of C. pepo dry mass taken in 750ml and 500ml of ethanol solvent.6 components/functional groups were confirmed in crude dye fractioned with n hexane, chloroform and ethyl acetate but only 4 components/functional groups were confirmed in crude dye fractioned with acetone

Dye is a coloured substance that chemically bonds to the substrate to which it is being applied. This distinguishes dyes from pigments which do not chemically bind to the material they colour. Dye is generally applied in an aqueous solution, and may require aftertreatment to improve the fastness of the dye on the fibre.
Dyes are usually soluble in water whereas pigments are insoluble. Dyes selection is very important when dyeing different types of textile fibre. Types of chemical dyes are Direct, Reactive, Vat, Sulphur dyes etc. All dyes required different chemical auxiliaries and different after treatment process. Each dyes possess different light, washing & rubbing fastness and having different characteristics also.
Luminophore BHT 115% is a highly substantive optical whitening agent for all natural, regenerated cellulosic fibres and polyamides. It is applied in hot alkaline liquors and gives particularly strong and brilliant white effects on cellulosic fibres. In the case of polyamide the pH should be adjusted to 4.5 with dilute acetic acid.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

2. 2
Application :
Due to its powerful detergent activity and low foam property Altranol-EPLF advantageously
replaces conventional scouring surfactants employed in batchwise and continuous
preparation processes Altranol-EPLF allows significant improvement in productivity. It is
particularly useful in single-stage combined desize/scour/bleach operations for woven and
knitted fabrics, terry-towelling and yarn packages.
On polyester-based fabrics, removal of synthetic sizing agents (especially acrylates which are
used to facilitate the weaving operation on water-jet looms) poses a major problem.
Altranol-EPLF expeditiously cleans out such polymers in short treatment times.
A. Batchwise Processing-
(i) Scouring of cotton hosiery-
Set the bath at liquor ratio 10:1 with
ALTRANOL-EPLF 0.5 – 1.0 g/l
Caustic Soda solid 3.0 g/l
Start at 50ºC, raise gradually to 95ºC and run for 30 mins. Cool to 70ºC.
drain and neutralise with
Acetic acid (80%s) 0.5 g/l
at 70ºC for 10 to 20 mins.
(ii) Scouring of polyester-cellulosic blended fabric-
Set the bath at liquor ratio 10:1 with
ALTRANOL-EPLF 0.5 – 1.0 gl/
Soda Ash 5.0 g/l
Sodium Perborate 2.0 g/l
Start at 40ºC, raise to 95ºC in 15 min., run for 30 mins. Cool to 70ºC
drain and hot rinse at 70ºC.
(iii) Desize-scour of Polyester or Polyamide fabric-
Set the bath at liquor ratio 10:1 with
ALTRANOL-EPLF 1-2 g/l
Soda Ash 5.0 g/l
Run for 30-40 mins at 100ºC for polyester (or 80ºC for polyamide), cool
to 70ºC, drain and wash thoroughly at 70ºC.
(iv) Combined preparation scour-bleach on cotton hosiery and terry-towelling on
winch or soft-flow machines-
Set the bath at liquor ratio 10:1 with
ALTRANOL-EPLF 0.5 - 1.0 g/l
ECOSOFT-400 0.5 g/l
and load the fabric while raising to 60ºC then add
Hydrogen Peroxide 50% 2.0 -5.0 g/l
Caustic Soda Solid 2.0 - 3.0 g/
MODQUEST-WS/PEROSTAB-BLN or 1.0 - 2.0 g/l
MODSTAB-MS
LUBASSIST-JET 0.5 - 1.0 g/l
3. 3
and raise to 90-95ºC in 20 mins. Maintain the temperature for 60-90
mins., cool to 70ºC and drain. Rinse in a fresh bath for 10 mins at 60-
70ºC with 0.5-1.5 g/l NEUTROX-ALN and acidify to pH 6-6.5 before
draining.
For fabrics to be marketed as white, an initial scouring treatment
followed by the bleaching process (preferably incorporating a
compatible optical whitener) yields optimum results.
B. Continuous Processing-
(i) Single-stage desize-scour-bleach for cotton hosiery and low-sized terry-toweiling
in J-Box-
Impregnate in saturator at 100-120% pick-up with
ALTRANOL-EPLF 1-2 g/l
ECOSOFT-400 2-3 g/l
Caustic Soda solid 4-6 g/l
MODSTAB-MS 5-6 g/l
Hydrogen Peroxide 50% 20-35g/l
and steam at 100ºC for 90 mins followed by wash-off at boil.
In Continuous Kier-
The process is carried out at 90-95ºC employing a liquor ratio of 10:1-8:1 with
fabric treatment for 1 hour followed by a squeeze, and washing-off/souring in
a separate washer. A continual gravity feed maintains the effective
concentrations in the kier-liquor. A full white can be obtained with the
following recipe (percentage on weight of material):
ALTRANOL-EPLF 0.5 - 1.0%
ECOSOFT-400 0.5 – 1.0%
MODSTAB-MS 1.0 - 2.0%
Caustic Soda solid 1.0 - 1.5%
Hydrogen Peroxide 50% 3.0 - 5.0%
alongwith a compatible optical whitener. For fabric to be subsequently dyed,
NEUTROX-ALN may be added in the washer at 60ºC to quench residual
peroxide, followed by acidification to maintain pH at 6-6.5.
(ii) Desize-scour-bleach on Pad-Steam range-
Desize by padding at 60ºC and 80-100% pick-up with
ALTRANOL-EPLF 1 g/l
Enzyme desizing agent 2 g/l
and roller-bed steam at 98-100ºC for 10 mins. followed by wash-off at 80ºC.
Scour by padding at 85ºC and 80-100% pick-up with
ALTRANOL-EPLF 3-5 g/l
Caustic Soda solid 10-15 g/l
and roller-bed steam at 98-100ºC for 10 mins followed by thorough wash-off at
boil. Bleach by padding at room temperature and 80-100% pick-up with
ALTRANOL-EPLF 3-5 g/l
4. 4
Caustic Soda solid 10-12 g/l
Modquest-WS / Perostab-BLN 4-5 g/l
or MODSTAB-MS
Hydrogen Peroxide 50 15-20 g/l
and roller-bed steam at 98-100ºC for 3 mins. followed by thorough wash-off at
near boil.
Alternatively, a combined single-stage preparation can be employed for low-
sized grey-
Pad the fabric at room temperature at 80-100% pick-up with
ALTRANOL-EPLF 5-7 g/l
Caustic Soda solid 12-15 g/l
ECOSOFT-400
MODQUEST-WS / PEROSTAB-BLN 5-8 g/l
Hydrogen Peroxide 50% 40-60 g/l
and roller-bed steam at 98-100ºC for 15 mins. followed by thorough wash-off at
near boil.
(iii) Desize-scour-bleach by Cold Pad-Batch for woven cotton and polyester-cotton
fabrics-
Desize by padding at room temperature and 80-100% pick-up with
ALTRANOL-EPLF 2-3 g/l
Enzyme desizing agent 5-10 g/l
and batching overnight at room Temperature followed by thorough
wash off at boil,
Scour-bleach by padding at room temperature at 80-100% pick-up with
ALTRANOL-EPLF 5-8 g/l
Caustic Soda solid 15-25 g/l
MODSTAB-MS 7-10 g/l
Hydrogen Peroxide 50% 30-45 g/l
and batch at room temperature for l5-24 hours followed by thorough
wash-off at boil.
Storage: Good shelf life under normal storage conditions. Containers must be tightly closed
when not in use.
Packing: 30, 50, 100 & 200 kg HMHDPE containers.
