The plasma elimination half-lives ranged from 38 to
43 hours in males and 78 to 82 hours in females. Tissue distribution of the
absorbed dose was extensive, with low retention in tissues indicating low
potential for accumulation. The tissue residues were higher in female than in
male rats, which is consistent with female rats having a longer elimination
half-life and higher area under the curve in plasma. Excretion was
substantially complete by 48 to72 hours after dosing. Fecal excretion was the
primary route of elimination followed by urinary excretion. There was no
significant excretion occurring by exhalation. Most of the administered dose
(88–97%) was eliminated in the excreta.

In short-term studies, the most consistent
effects are those associated with non adverse pharmacological response to the xenobiotic, induction of liver
enzymes and subsequent increase
in liver weights. Emamectin Benzoate is not genotoxic, neurotoxic, immunotoxic, carcinogenic, or teratogenic.
Overall, Emamectin Benzoate exhibits minimal mammalian toxicity after long-term exposure. The only consistent observation
in the mammalian toxicology
studies is an increased degree of microvesiculation of the adrenal cortex after dermal or dietary administration of
Emamectin Benzoate. Based on the lack of adverse effect on the function of the adrenal gland, this observation
was considered treatment related,
but not “adverse.”
It prevents the
removed substances from precipitating back again on the fabric during
scouring and post – bleaching washing processes due to its ability of complex
formation with earth alkaline metal ions. Thus, a better
whiteness and hydrophility is obtained in cotton bleaching process.It is a very
effective complexing agent, which prevents the formation of precipitations
due to water hardness and heat in wet mediums.It is
an efficient chelating agent for alkaline earth- and heavy metal ions.
The built
chelates are stable up to boiling temperature and even in strong alkaline
mediaCompatible with
optical brighteners.

Implementing enzymatic removal of residual hydrogen peroxide after bleaching
To achieve reproducible bleaching results, residual hydrogen peroxide content of 10-15% of the initial quantity should be still available after bleaching. The residual hydrogen content must be completely removed to prevent any change of shade with dyestuffs, which are sensitive to oxidation. Reducing agents and several rinsing steps are necessary in common peroxide removal techniques. High energy and water consumption and the use of sulphur containing reducing agents are the main disadvantages of the conventional technique.
Special enzymes (peroxides) catalyse the reduction of hydrogen peroxide to oxygen and water. No side reactions with the substrate or with dyestuff occur.
Peroxides are completely biodegradable. Rinsing steps after peroxide bleaching can be reduced (normally only one rinsing step with hot water is necessary). Peroxides have no negative influence on downstream dyeing processes. Therefore, after treatment with the enzymes in an exhaust process the liquor does not have to be drained prior to dyeing. Savings in energy and water consumption can be achieved. Wastewater pollution with reducing agents (used for conventional processes) is avoided.
Enzymatic peroxide removal is possible in a discontinuous, semi-continuous, and continuous way. The method is applicable both in new and existing installations.
No capital expenditure is necessary for implementation of the enzymatic process. Savings may result from reduced washing stages, i.e. water, energy, steam and time conservation. Savings in water and energy consumption can be in the range of 6-8% of production costs (exhaust technique) .
Suppliers for enzymatic peroxide removal agents are: Novozymes, Bayer, Ciba, etc
A typical process consequence is: peroxide bleaching – liquor change – one rinsing bath (hot water) – liquor change – enzymatic peroxide removal – dyeing without previous liquor change.
Heavy Duty Washing Machine – One of the most important options to reduce the environmental impact of industrial processes is to minimize the number of required process steps necessary to produce the desired quality of products. As an example, instead of traditional pre-treatment of textiles, the minimum required treatment processes can be applied. The pre-treatment of the fabrics depends on the desired colour depth and other characteristics of the finished product. For example, fabrics that will be dyed in dark colours should not be strongly bleached.
Oftentimes, reducing the number of
process steps is possible through treating the fabrics in wet conditions,
without the need to dry them first. This allows certain process steps to be
combined which normally are carried out separately. Examples that have been
implemented include:
Improvement of the feel of yarn
directly after painting without drying the material first;
Making wool moth repellent during
dyeing;
Development of a single step
pre-treatment of the fabric that combines washing, scouring and bleaching in
such a way that one washing / drying stage can be omitted. Depending on the
type of textiles treated, one step pre-treatment can yield substantial energy
and water savings because two or even three of the wide washing steps can be
reduced to one. One-step pre treatment is especially feasible for textiles that
are relatively light weight;
Wet-in-wet impregnation of
treatment chemicals, in order to skip a drying stage. Many treatments of
fabrics can be applied directly on the wet cloth after the wide washing
process. In that case, the cloth is impregnated “wet-in-wet”,
followed usually by a reaction step in order to let the chemicals work on the
fabric. Afterwards, the cloth is rinsed on a wide washing machine. Examples of
this process include: (1) The wet-in-wet pre-treatment on a continuous
pre-treatment line; and (2) the wet-in-wet application of a cationic treatment
chemical after rinsing out unabsorbed reactive pigments;
Combined dyeing and application of crease repair agents (synthetic resins) so the material only has to be dried once.

For Denim-
Yellowish marks come from chemicals & from back staining.
Indigo dyes have big molecule structure, so after washes it’s come back to the garments again. Sun lights affect those molecules & make the garments yellow. So we have to wash it clearly and use the anti ozone (O3) softener.
To prevent crease marks reduce RPM & temperature at desizing stage.
To avoid uneven increase pH. At lower pH bleach work quickly & makes uneven.
Use buffer solution to stable pH. For pH changing shades will change also.
Hypo must be clear to prevent Yellowish effect

Sampling and Traditional Parameters
Installing light sources close to the work place is potentially profitable in case there are variations in the illumination required in the halls. In storage facilities this is usually not an option. Installing light switches in each hall and even over each working place is applicable when there are a number of halls for different production processes. It is not similar to Tubeless Lab Dispenser The pay back time of this measure is usually between 1 and 3 years. The International Commission on Illumination (CIE, http://www.cie.co.at/cie) and the International Standard Organization ISO have jointly published a standard governing lighting for indoor work places, taking into account energy efficiency. This standard ISO 8995:2002/CIE S 008/E:2001 called “Lighting of Indoor Work Places” may be obtained The member price is USD 51, whereas the list price

Applying Single Desizing
Cellulosics and their blends with synthetics could be desized, scoured and bleached in a single stage. This could reduce the processing time by a considerable extent, apart from reducing the water consumption and wastewater generation.
This measure has been implemented in number of units in India, particularly for the batches where the final dyed product is of a dark shade. In these situations no adverse effect on the quality was observed. The improved environmental impact is due to the fact that all three processes could be carried out in just one bath (instead of three different baths for thrice the duration and having rinses in between). Furthermore, as in earlier mentioned options, the industry concerned would need to make a few trials before commercial implementation.
Reduced process time and energy
Reduced water consumption
Reduced wastewater generation
Reduced cost of effluent treatment
Applicable for cellulosics and their blends only. Combined process for desizing, scouring and bleaching is particularly suitable for fabrics in dark shades, where the bleaching requirement is low. However, this could also be applied for medium shades, depending on the efficiency of the combined process.
The savings are obvious because of the reduction in the number of stages as well as the process time and water.
Conclusion
Tube Dispenser -Illegal discharge of wastewater or bypassing treatment facilities will not be tolerated
