Custom Long Sleeve T-Shirts

Long Sleeve T-Shirt Manufacturer Bangladesh

Siatex Bangladesh is a long sleeve t-shirt manufacturer and exporter supplying custom long sleeve tees to brands, workwear buyers and promotional clothing distributors in the USA, the UK, Germany, Canada and Australia. Every shirt is knitted and sewn in Bangladesh to the buyer's fabric, colour and size specification on a confirmed order, under the buyer's label.

Materials - Cotton single jersey forms the soft breathable body, with interlock knitted where a firmer opaque cloth is specified and rib knit at the collar and cuffs. Cotton elastane blends add gentle stretch where the fit needs it, and fibre, weight and handle are set to your specification.

Functionality - Long sleeves cover the arms for cooler seasons and layer cleanly under shirts, jackets and workwear, while ribbed cuffs hold each sleeve at the wrist. The jersey body takes chest and sleeve prints evenly, and the cloth breathes in wear and washes without losing shape.

Size - Mens and unisex ranges are graded from your measurement chart, with chest, body length and sleeve length set per size so the shirt drapes evenly from the smallest size to the largest.

Customisation - Colours, prints and labels follow your brief: white, heather grey and olive lead the first story, with chest prints, sleeve prints and embroidery placed to your guide. Every long sleeve t-shirt is made to order under your brand: no ready long sleeve t-shirts sit waiting, and sewing begins when your order is confirmed.

Long Sleeve T-Shirt Fabrics: Single Jersey, Interlock and Rib Knits

The cloth decides how a long sleeve body feels through the day, and a sleeved garment uses more fabric than a short sleeve style, so weight and shrinkage are settled before knitting starts. Every quality is sampled in your colour first, so drape and handle are approved before bulk.

  • Cotton single jersey for a soft breathable body
  • Cotton elastane jersey with gentle stretch
  • Interlock jersey for a firmer opaque cloth
  • Brushed-back jersey for a warmer inside
  • Slub jersey for a soft textured surface
  • Heathered yarns for depth of colour
  • Rib knit for collars and cuffs
  • Printed bases developed to your artwork
  • Other buyer-specified fabrics to your hand feel

The same single jersey qualities knit our core t-shirt programmes, so short and long sleeve styles in one range hold a single hand feel.

Custom Long Sleeve T-Shirt Sizes, Fits and Size Ranges for Germany and UK Buyers

Sleeve length is the measurement buyers notice first, so size sets are graded from your chart with chest, body length and full sleeve length moving together. Regular and relaxed fits are cut to your blocks, with the cuff set to sit at the wrist on every size.

German buyers usually confirm one base size with fit comments before grading, while labels selling in the UK often add body length for layering. A ladies line grades beside the mens range from our ladies t-shirt blocks, keeping one size logic across the family.

Long Sleeve T-Shirt Construction: Set-In Sleeves, Ribbed Cuffs and Seams

The arm takes more movement than any other part of a garment, so construction is specified before sewing starts. Sleeves are set in with a smooth shoulder line, and cuff, collar and hem finishes are fixed in the specification.

  • Set-in sleeves eased for a smooth shoulder
  • Ribbed cuffs gripping the wrist, recovering shape
  • Rib knit or self-fabric collar bands
  • Shoulder tape keeping the neckline line
  • Coverstitched hems and cuff joins
  • Side-seamed or tubular bodies to specification

A chest pocket style follows the same discipline as our pocket t-shirt range: the pocket is set square and bar-tacked before the garment closes, so the front stays clean after washing.

Customising Your Long Sleeve T-Shirt: Chest Prints, Sleeve Prints and Colours

The long arm adds a second print position a short sleeve style cannot offer, so decoration is planned across chest, back and sleeve from the first sample.

  • Chest and back prints to your artwork guide
  • Sleeve prints down one or both arms
  • Embroidery at chest or cuff
  • Colour stories around your seasonal palette
  • Your labels, hangtags and packing to artwork

Buyers in the Netherlands often build decoration around one strong sleeve print and keep the body plain. Dye effects are developed in the same round as our tie-dye t-shirt work, so washed and dyed styles share one colour language.

Long Sleeve T-Shirt Sampling and Product Development

Sampling turns your sketch, tech pack or reference garment into a finished shirt before bulk is committed. The pattern is developed, cloth and trims confirmed, and a pre-production sample is prepared in your base size with sleeve length checked against your chart.

Sleeve shapes are proven at the same stage, from set-in arms to the raglan lines of our raglan t-shirt styles. Danish buyers often approve both fits on one sample round, then release the stronger seller into bulk.

Long Sleeve T-Shirt Quality Assurance and Production Follow-Up

Quality is protected by checking rather than promises: our quality team follows your order from fabric inspection to final packing. As a family-run manufacturer, we treat every t-shirt as a garment your name depends on, so the sampling standard is held through bulk.

  • Fabric shade, weight and shrinkage checked pre-cutting
  • Sleeve lengths measured as a matched pair
  • Cuff stretch and recovery checked inline
  • Print position checked against your artwork
  • Measurements reviewed against your chart pre-packing
  • Final shirt-by-shirt inspection before cartons seal

Any shirt falling short of the approved t-shirt standard is remade or rejected before packing, never passed through.

Ordering Your Long Sleeve T-Shirt: Terms, Approvals and Repeat Orders

Starting is simple: send a tech pack, a reference sample or a clear sketch of the t-shirt style you want built. Drawing on 37 years of experience, our team replies with fabric options and a sampling plan, and prices are quoted per style against your specification.

Commercial terms are agreed in writing before production: payment method, delivery schedule and quantities are set style by style in the order confirmation. Approvals stay with you at sampling, pre-production and dispatch, so the finished range is the range you signed off.

Shipping and Delivery of Your Long Sleeve T-Shirt Order

Finished garments are folded and packed to your instruction, each t-shirt tissue-folded so the sleeves arrive crease-light, and cartons are marked to your template. Consignments ship from Chattogram port, with the UAE served on regular sailings for buyers selling there.

Freight is booked around your delivery window, by sea for bulk volume or by air when a launch date is tight. Carton weights and measurements reach you before booking, and your merchandiser confirms dispatch as soon as the goods leave Bangladesh.
