Air Jet Loom

Airjet loom carrying the yarn via shed is known as Air jet loom. Air jet loom has biggest weft yarn insertion performance and considered as the most productive of the manufacturing of light to medium weight fabrics, preferably made of cotton and certain man made fibers. Aair jet looms are the ideal solution to produce bulk quantities of customized fabric styles. The weaving widths range generally from 192 to 400 cm for jet air of air jet mill. [1]

Expected Sales Revenue By Four Looms Per Year

At present most of the Label looms owner used to calculate the Label as 1:1 Basis i.e.

ONE RPM = ONE US DALLAR.

Our Loom will run 1250 RPM we calculate production value minimum US$900.00 per 20 hours (one day) x 25 days/month x 3 Looms x 12 months = US$8,10,000.00

One US$ equivalent BDT.85.00 = BDT.6,07,50,0000.00

Tradition of label costing:

75mm

25mm loom is 211mm/section x 8, if label width

25mm then production at a time 64 pcs.

1. Ground colour (Cutting to Cutting)   75mm +
2. Lettering colour (colour to colour)     55mm

130mm x 2.8 (Density) = 364 picks.

Normal formula for costing a label RPM 950 ÷ 364 picks = 2.60 x 20 hrs x 60 x 64 pcs.

Per day production 16,703 dozen.

Target price is minimum US$900.00 ÷ 16,703 dz = US$0.0538/dozen/

Therefore, 16,703 dz x US$0.0538.00 = US$898.62

Say US$900.00 per day production by one loom.

Conclusion

• Demand of products (Woven Label) in our country the garments export has been increase day by day. Each & every type of Garments must be stitched one Brand Label, (Main Label) Tab Label, pocket Label, Size care label etc. At present more than 50% of woven Label is imported from Hong Kong. Pakistan
• If we established the project in world standard then it will be easier to sale to the international renowned Buyers.
• In the light of above facts & figures we can do believe that this is a most viable project to the investors. If they do business minutely they must be able to pay back their liabilities within 48 to 55 months  positively.
• Auto garment was established in 2013

at GERMAN. Their textile & Woven Label loom is the best of all because:

1. Softest edge.
2. 6mm width label is possible (No label loom can do).
3. Generation to generation will run the jacquard loom.
4. “Made in Germany” is a well & trusted name in the Textile Machinery world.
5. The world renowned customers will be interested if they know that Label is made by auto loom.
6. We should invest the money in the best way.

How to Make a Loom:

Jet air weaving require air ducts capable of maintaining an effective air flow on the whole weaving width. To obtain this, the machine manufacturers prefer today to use the system with profiled reed, in which the air and the thread are guided through a tunnel shaped in air jet mill.
