DIFFERENCE BETWEEN SAND BLAST AND HAND SAND PROCESS
Sand Blasting:
This process is done by gun with the help of air flow.
01.total indigo is out so slap is down
02. Metal con be found sometimes.
03. Effect is on top of surface.
04. Less yarn character.
05. Process is faster.
06. Environmental hazardous
07. Health hazardous.
08.Production high.
09.Easy to control.

Hand sand:
This process is done
by manually with the help of abrasive paper.
01. Inside
indigo stay, so that slap is increase.
02. No
possibilities to found metal.
03. Effect is
in depth of surface.
04. Effect is
in depth of surface.
05. More yarn
character.
06. Process is
length.
07. Environmental
hazardous.
08. Also health
hazardous.
09. Production
low.
10. Sometime
unevenness.
11. Difficult
to control.
Whisker:
Whisker is done making a pattern and put in the garments
then remove color from pattern area. Whisker is the most important dry process
for denim garments. After wash, we can
see the pattern mark. It is one kind of design on the garments.
Whisker are two types depends on the process.
01.Manual Whisker.
02. Laser Whisker.
Manual Whisker:
This whisker is done by manual with the help of pattern. On
denim garments we have done it by abrasive paper. This whisker absorb the color
homogeneously.

Material needed for manual whisker
01. Pattern
board.
02. Water
paper.
03. Marking
Chalk.
04. Foam.
Laser Whisker:
This whisker is done by laser machine. First we have ti make
a design in the Photoshop Illustrator
then it insert into laser machine and fix the intensity and impose in the
garments according to making and burn the indigo. After wash the burned indigo
will remove and whisker will see. This production is more but the tint absorb
is very uneven;.

Equipment and materials:
01. Leaser
machine
02. Leather
hand gloves and goggles for safety.
Destroy:
Destroy is a process which is done by pen grinding machine
machine. First we have to mark the garments then slightly attached this machine
with the garments then slowly remove the cellulose. After wash can get a good
destroy look of garments. This process we can done by another method.

Materials need for destroy:
01. Destruction
Machine.
02. Marking
Chalk.
03. Pattern
Board
04. Hand
gloves for safety.
P P Spray:
Mans potassium
permanganate spray on the garments at specific area. We sprayed then chemicals
to reduce the color from garments. First we have to put the garments into dummy
then take air. Then we spray PP gun by air pressure. Then we spray pp with the
help by air pressure. This spray is done
on the scrapping area and after neutralize we got a white look on the spray
area.
Tagging:
Tagging is the process which is done at unwashed condition
of garments. After wash we will get it effect. Maximum time we will do it at
edge area by folding the garments. This process can be by the tag gun, plastic,
staple machine or manually. Sometimes this process damages the garments by
creating hole.

Grinding:
Grinding is the
process by which we get the used effect of garments. This process is completely
Done at edges
area. If the garments has tow time wash that time we will wash it after wash to
avoid the damages of garments.

Crinkle:
Crinkle is the process by this we squeeze the garments at
front and back knee area. This process is done by crinkle machine or by manual
clopping of specific area, First time we have to spray the resin on the marked
area then clopping the garments and put into curing oven at 150c at a specific
time. Another process is after resin spray, squeeze.
