Cotton gabardine trench coat manufacturer in Bangladesh

A cotton gabardine trench coat is cut from a tightly woven cotton twill with a steep diagonal and a dense face, finished to repel water. The weave lets the coat breathe while the finish makes rain bead and run off, which is why the cloth has stayed the standard for trench coats. Buyers looking for a cotton gabardine trench coat manufacturer in Bangladesh are usually stocking a classic or heritage range where the cloth is the selling point.

The gabardine is woven and finished at a mill before the factory cuts it, so most questions are about the cloth. State the weight, fibre, finish chemistry and spray rating you need; both quotes then come back on cloth that meets them, with test reports built into the timeline when asked for on the quote form.

Kinds of cotton gabardine trench coat

Heavy cotton gabardine trench

Around 250 to 280 GSM, crisp and firm, for an autumn coat that holds its shape. It resists wind and creases less, but wears warm in spring.

Light cotton gabardine trench

Around 180 to 220 GSM, softer and cooler, for a spring and summer coat. It drapes and creases more, and a lining helps it hang.

Poly cotton gabardine trench

Polyester blended with cotton for a lower price, stronger yarn and less shrinkage. Close to cotton in look, but less dry in the hand, and it can shine at pressed seams.

Fluorine free finished trench

Gabardine with a repellent finish free of fluorinated chemistry, which many buyers now ask for. It repels water but not oil, and its rating can drop sooner with wear.

What to tell a cotton gabardine trench coat manufacturer in Bangladesh about the cloth

Fibre and yarn

100 percent cotton or a poly cotton blend. For cotton, combed two ply yarn gives the tight, smooth face gabardine depends on.

Weave and density

A steep, warp faced twill with a high warp count is what sheds rain. Ask the mill for ends and picks per centimetre and keep them on the approved cloth record.

Weight

Usually 180 to 280 GSM for a trench, given with a tolerance, typically plus or minus 5 percent, and checked on bulk.

Repellent finish

Fluorine free or fluorinated, and any restricted substance list it must meet. Applied and cured at the mill, it covers more evenly than a finish added after sewing.

Spray rating

The target new and after washing or cleaning, measured by one method throughout, so results from sample and bulk can be compared.

Care and reproofing

Dry clean or washable, plus a reproofing instruction on the care label, since the finish wears and has to be renewed.

Tests for a cotton gabardine trench coat

AATCC 22

Spray test rated 0 to 100 against reference photographs, the method US buyers commonly name. Ask for the rating new and after the agreed number of washes.

ISO 4920

The ISO spray test, graded on its own scale where 5 means no wetting or sticking. Agree one method with the buyer and keep to it from lab dip to bulk.

ISO 11092

Water vapour resistance, Ret. It shows how well a dense gabardine still breathes next to a coated cloth, useful when the coat is sold on comfort as well as rain.

ISO 3801

Weighs the gabardine per square metre. Cloth delivered light often has a looser weave and sheds rain less well, so check bulk against the approved weight.

What moves the price of a cotton gabardine trench coat

• Fibre: 100 percent cotton gabardine costs more than poly cotton of the same weight.
• Yarn: two ply combed cotton costs more than a single yarn but gives the dense face.
• Finish: a durable fluorine free repellent finish usually costs more than a basic one.
• Weight: heavier gabardine uses more yarn per metre.
• Testing: spray ratings new and after washing, plus breathability if it is claimed.

Lead time for cotton gabardine trench coats

On a gabardine trench the cloth sets the pace. Gabardine woven or dyed to order adds mill time, and the repellent finish is applied and tested at the mill before the cloth ships. A spray test on washed bulk cloth adds days at the lab. The quote lists the cloth lead time separately, and order confirmation to shipment usually falls within 60 to 90 days.

What we check on cotton gabardine trench coats before shipment

• Spray rating on bulkA panel of bulk cloth or a finished coat is spray tested and meets the agreed rating before packing.
• Shade and twill directionPanels cut from different rolls match in shade, and the twill line runs the same way on every panel.
• Needle damageSeams on dense gabardine show no needle holes or puckering, which would also open paths for water.
• Care label wordingThe label carries the reproofing instruction and says water repellent, not waterproof.
