Lab dip is a process by which buyers supplied swatch is matched with the varying dyes percentage in the laboratory with or without help of “DATA COLOR”
Lab dip plays an important role in shade matching & and detaching the characteristics of the dyes and chemicals are to be used in the large scale of production. So this is an important task before bulk production.

Basic knowledge about blend dyeing
Dyeing of Blended Fibres & Fabrics
Blends:
Blends are any textile material from fiber through yarn to fabric which are deliberate combination of chemically or physically different fibrous polymer. Cotton and Polyester blend is an example of chemically different blend and Cotton and Viscose is physically different blend because both are cellulosic.
Reason for blending:
1.Economy: The dilution of an expensive fibre by blending with a cheaper substitute.
2.Durability: The incorporation of a more durable component to extend the useful life of a relatively fragile fibre.
3.Physical properties: A compromise to take advantage of desirable performance charactristics contribuition by both fibre components.
4.Color: The development of new fabric design for garments incorporating multicolor effect.
5.Appearance: The attainment of attractive appearance & perceptible qualities using combinations of yarns of different lusture, crimp or denier which still differ in appearance even when dyed with same color.
6.Other reasons-
Blending develops fibre properties.
Colorant modification is possible by blending.
Finishing process modification.
Improved moisture absorption, antistatic characteristics, reduced pilling, improved abrasion resistance.
Dyeing Possibilities with Blends:
1.Union Dyeing:
• This is suitable for fabrics containing two fibres to dye them in a single uniform colour, each dye suitable for one kind of fibre in the blend.
• Union dyeing is same as cross dyeing except that instead of multi-colour effects. One solid colour is produced. The dyer accomplishes this by using two or more classes of dye, each of the same colours.
• Different fibres may require different dyes to obtain the same colour; this may be done by putting the appropriate colour dye that is specific to each type of fibre in to one dye bath.
• For eg: a fabric composed of rayon and acetate can be dyed with a solid colour green by using a direct dye for the rayon, and a disperse dye of the same colour for the acetate.
2.Resist/Reserve dyeing:
• In resist dyeing at least one (but not all) of the components of the blend remains essentially undyed i.e almost white.
3.Cross dyeing:
• Cross dyeing produces fibres of contrasting color
• This is two types-
a)Shadow effect/Tone-in-Tone dyeing:
Two fibres are dyed in same hue & brightness but the depth is different. It is called tone-in-tone or shadow effect.
b)Contrast effect:
Two fibres are dyed with strong difference in hue, brightness & depth.This is called contrast effect. Pleasing final appearance is important here.
Textile printing is the most versatile and important of the methods used for introducing color and design to textile fabrics. We may print as a fabric form or apparel form
A wrinkle, also known as a rhytide, is a fold, ridge or crease in the cloth or garments. Wrinkle is a particular type of pressure in the finished fabric. It is produced during finishing operations by the thickness of the seam used to join pieces for processing.Resin & its use in Denim garments industry to create unique & vintage looks which add value to denim garments & improves it sale ability in market. In 80’s we have seen Resin being used to give non press , iron free trousers & now we are using in Denims to make wrinkles & creases to look natural vintage which stays after multiple home laundries.
Wrinkle resistance varies from quite low in many fabrics to very high in resilient fabrics. In order to form a wrinkle, a fabric’s wrinkle resistance must be overcome. The fabric may, however, produce strains and store potential energy that can become evident as wrinkle recovery under suitable conditions.Resin & its use in Denim garments industry to create unique & vintage looks which add value to denim garments & improves it sale ability in market.

The finishes are applied on leather generally by brushes and pads and finally by hand spray and this practices is still very widespread in major tanneries.
Although automatic spraying machines are becoming popular in large tanneries as large quantities of leather can be produced by automatic conveyer belt spraying machine.

In the Adani-Hindenburg case, what is SEBI investigating.pptxAdani case
Adani SEBI investigation revealed that the latter had sought information from five foreign jurisdictions concerning the holdings of the firm’s foreign portfolio investors (FPIs) in relation to the alleged violations of the MPS Regulations. Nevertheless, the economic interest of the twelve FPIs based in tax haven jurisdictions still needs to be determined. The Adani Group firms classed these FPIs as public shareholders. According to Hindenburg, FPIs were used to get around regulatory standards.
Implicitly or explicitly all competing businesses employ a strategy to select a mix
of marketing resources. Formulating such competitive strategies fundamentally
involves recognizing relationships between elements of the marketing mix (e.g.,
price and product quality), as well as assessing competitive and market conditions
(i.e., industry structure in the language of economics).

3. Wool Fibers
Wool Quality depends mainly on the fiber diameter;
the smaller the diameter , the finer and more
valuable the fiber . Fine qualities come mostly from
Marino sheep which can be spun into finer yarn
counts.
4. Wool Fibers
Course wool comes from cross breed sheep and
they are spun into coarser yarn counts
5. Marino Wool mainly comes from Australia and South Africa .
It has a fiber micron of range from superfine 16 micron up to fine 25 micron
Cross breed wool mainly comes from New Zealand which has fiber micron
range from 25 micron up to 40 micron
( Micron = 1/1000 millimeter = 1/million meters
6. • Special Decorative Effects can
be produced on wool products
by various chemical
treatments and various
printing techniques .
• Five of these effects are
discussed in this presentation .
7. First The luster Mohair like effect on the wool fabric
The principle of this
process is to increase
smoothness of the wool
fiber surface by chemical
treatment which attack
fiber surface scale
Attacking surface scales
result in smooth fiber
surface and hence
increase light reflectance
giving luster effect
8.
9. Second : Heat Transfer Printing on wool fabric
The process is based on
use of sublimation disperse
dyes capapble of forming
complexes with chromium
metal .
Transfer printing is carried
out on calendars with high
blanket pressure at 200C
.The process can be used
for 60/40 Wool / PET
Fabric
10.
11. Third : Burn Out Effect or Devore
Effect
The process is done on
wool/polyester blended
fabric.
The effect is produced by
printing the fabric with a
thickened solution of
sodium hydroxide which
destroys the wool in the
print areas producing the
effect
12.
13. Fourth : Panel Printing
(direct and resist printing on
knitwear garments )
Direct & Resist printing on
Knitwear garments. There
are 3 variations of the
process:
Direct, resist and dye/resist
printing
The printing technique is
simple and based on cold
batch technology
14. Fourth : Panel Printing
(direct and resist printing on knitwear garments )
Printing of garment panel
with paste containing
selective reactive dyes and
chemicals which facilitate
cold fixation
Garment after printing is stored
cold up to overnight . If ecru
prints are required on dark
grounds they can be reduced
by incorporating dye resist
agent (Sandospace R in
printing paste prior to garment
dyeing
15. Fifth : Sculpture effects through Panel
Printing of Knitwear garments
The basic principle of the
process to print the design
with thick solution of
suitable shrink -proofing
agent ( Anti-felt agent) onto
unfinished garement
followed by scouring and
milling
Effect is produced due to resistance
of printed areas to milling action so
the sculpture appearance is
produced. The process exploits the
natural property of wool to felt under
action of moisture and pressure
during milling . Felting is produced
in wool due to presence of scales
an wool fibers surface.
