Garments Manufacturing
Introduction:
The processing steps and technique involved in the manufacturing garments for large scale production on industrial basis for business purposes is called garments manufacturing technology.
Garments Factory
The factory producing garment from woven fabric is called woven garment factory. The factory producing garment from knit fabric is called knit garment factory.To produce garments we need sewing machines but the sewing machines are of different types used for different specific type of stitch.Name of some common sewing machines used in garments manufacturing are mentioned below.
1.Lock stitch sewing machine.
2.Chain stitch sewing machine.
3.Over lock sewing machine.
4. Flat lock sewing machine.
5. Kancasy sewing machine.
6.Blind stitch sewing machine
7. Bar tac sewing machine

Purpose of industrial garments wash
a) To remove size materials from garments as a result the garments become more soft with better hand feel.
b) To reduce dirt, spot, or germ from the garments,If added during manufacturing.
c) To create wash look appearance,which seems the new touch of fashion.
d) To create faded look,color or tinted affect.

Garments design and comfort
Garment design is related to beauty of clothing as well as also related to effectiveness. When we buy a clothing,we are careful to its beauty.color,design fashion etc matter as well as its expected effectiveness. Garment design may very depending on age,as well as environmental condition,Garment design also varies depending on area f use,for example design of clothing used for inside home is different from out side home.Garment design should be such that when clothing worm,should not create discomfort in any weather.
garments design for extremely cold weather is very important.Under such situation design of the clothing should be such that air can't pass through or get in easily through the collar,cuff,ankle,front opening and waist opening,Specially the outer garments for example jacket fabric should be water and wind resistant.If zipper is used in the clothing,should be protected from water and air getting inside through zipper,y using flap on the zipper.the width of flap should be wider to operate zipper and flap when hand gloves are used.Velcro is used instead of zipper for the manufacture of clothing for very old age people and for child,which are very easy to operate for them.
