Garment Manufacturing and Sourcing

Mirthuni Apparel Sourcing Service provides garment manufacturing and sourcing support for international fashion brands, apparel importers, retailers and private-label clothing businesses. Based in Tiruppur, Tamil Nadu, India, we coordinate knitwear garment production through selected manufacturing partners, covering technical development, pattern making, sampling, cutting, sewing, finishing, quality control, private labeling and export packing.

Our core garment categories include regular and oversized T-shirts, polo shirts, sweatshirts, hoodies, joggers, knitted shorts, loungewear, sleepwear and children’s knitted apparel. Each production programme is evaluated according to the buyer’s tech pack, fabric construction, measurements, workmanship requirements, quantity, quality standards and delivery expectations.

Our approach combines manufacturing coordination with technical sourcing support, helping buyers manage the transition from approved development samples to consistent bulk garment production.

Complete Knitwear Garment Manufacturing and Sourcing Process

Garment manufacturing involves several connected operations that convert approved knitted fabric into finished apparel. Each stage requires suitable machinery, trained production personnel, documented specifications and appropriate inspection procedures.

Garment Production Workflow

Buyer Tech Pack and Specifications → Technical Review → Pattern Development → Fit Sampling → Sample Approval → Fabric and Trim Preparation → Fabric Relaxation → Marker Planning → Cutting → Panel Inspection → Sewing and Assembly → Inline Quality Control → Garment Finishing → Final Inspection → Labeling and Packing → Shipment Preparation

Printing, embroidery, garment dyeing and special washing operations are integrated at the appropriate stage according to the approved production route.

Tech Pack Interpretation and Pre-Production Planning

Production begins with a detailed review of the buyer’s technical requirements. A garment tech pack establishes the intended design, fit, construction, fabric specifications, size measurements, branding details and finishing expectations.

Mirthuni Apparel coordinates the review of technical documentation with relevant production partners to identify construction requirements, material availability, manufacturing feasibility and potential development issues before bulk production.

Important Tech Pack Information

Garment design sketches and reference photographs
Fabric composition, construction, GSM and finishing
Measurement chart with points of measure and tolerances
Size range and grading requirements
Seam construction and stitch specifications
Collar, cuff, rib and neckline requirements
Printing and embroidery artwork with placements
Brand labels, care labels, hangtags and trims
Colourways and quantities per colour and size
Packaging, testing and destination-market requirements

Where a complete tech pack is unavailable, reference garments, photographs and preliminary specifications may support an initial feasibility review. However, approved technical measurements and construction details are needed before reliable bulk production.

Pattern Making and Garment Engineering

Pattern development converts the garment design into individual components suitable for cutting and sewing. Pattern accuracy influences garment fit, proportions, fabric consumption, seam alignment and overall appearance.

Initial Pattern Development

Patterns are developed according to the approved garment silhouette, fabric stretch, body measurements, seam allowances and construction requirements. Different garment categories require different pattern approaches.

For example, oversized T-shirts may require a dropped shoulder, wider body and adjusted sleeve geometry, while fitted tops may require closer attention to fabric recovery, stretch and body shaping.

Digital Pattern Making and CAD Support

Suitable computer-aided design systems may be used for pattern preparation, grading and marker planning. Digital workflows can support repeatability, technical revisions and efficient material utilization.

Pattern Grading

Grading develops the approved base-size pattern into the required size range. Grading rules should follow the buyer’s measurement chart and intended fit rather than assuming that all garments can use the same proportional increments.

Fit Development Considerations

Regular-fit, oversized, boxy, relaxed, cropped, petite and children’s garments require different pattern proportions. Measurements should be assessed together with fabric elasticity, recovery, shrinkage and the intended garment silhouette.

Fit approval should be based on an actual sample made from the approved fabric or a technically representative material.

Garment Sampling and Fit Approval

Sampling allows buyers to evaluate garment measurements, construction, workmanship, fabric behaviour, decoration placement and overall appearance before bulk manufacturing.

Development Sample

An initial sample may be produced to evaluate design feasibility, construction and general fit. Technical adjustments are identified before further approval stages.

Fit Sample

A fit sample is used to review measurements, garment balance, proportions, sleeve shape, neckline and other fit-related requirements. Buyer comments are incorporated into the pattern and construction specifications.

Size-Set Sample

Where required, size-set samples are used to evaluate grading consistency across the intended size range.

Pre-Production Sample

A pre-production sample, commonly called a PP sample, is prepared to represent the approved garment construction, fabric, trims, branding and finishing before bulk production begins.

Mirthuni Apparel coordinates paid sampling. As part of our standard commercial arrangement, 50% of the agreed sample charges are adjusted against the bulk order once the order is confirmed, subject to the agreed quotation terms.

Fabric Relaxation and Preparation Before Cutting

Knitted fabrics may retain tension from knitting, dyeing, finishing, rolling and transportation. Controlled fabric relaxation before cutting helps reduce the risk of dimensional changes after garment panels are cut.

Relaxation requirements depend on fabric construction, elastane content, finishing history and the fabric supplier’s recommendations. Suitable conditions should be established before marker planning and cutting.

Fabric Inspection Before Cutting

Incoming fabric may be checked for shade, width, GSM, surface defects, spirality and dimensional behaviour. Fabric rolls should be identified and managed to reduce unintended mixing of different shades or production lots.

CAD Marker Planning and Fabric Cutting

Marker planning determines how garment pattern components are arranged across the usable fabric width. Efficient marker planning can reduce cutting waste while preserving the required grain direction, pattern alignment and garment quality.

Manual and Computerized Marker Planning

Marker preparation may be performed manually or through suitable CAD systems. The appropriate method depends on garment complexity, order quantity, fabric width and production setup.

Fabric Spreading

Fabric spreading prepares the required number of plies for cutting. Operators must control tension, alignment, lay height and fabric direction, particularly for stretch materials, stripes and directional prints.

Industrial Fabric Cutting

Cutting may use straight-knife, band-knife or suitable automated cutting systems, depending on the production programme and partner-factory capabilities.

Cut components are identified, counted and bundled according to garment style, size, colour and production sequence.

Stripe and Pattern Matching

Yarn-dyed stripes, engineered patterns and printed fabrics may require additional marker planning and cutting controls to achieve acceptable matching at seams and garment panels.

Industrial Sewing and Garment Assembly

Sewing converts cut garment components into completed apparel. The appropriate stitch and seam construction depend on fabric stretch, garment application, durability requirements and desired appearance.

Mirthuni Apparel coordinates sewing operations using suitable industrial garment machinery through selected manufacturing partners.

Single-Needle Lockstitch Sewing

Single-needle lockstitch machines are used for suitable straight seams, attachment operations, labels, decorative topstitching and selected construction details. Stitch selection must account for fabric stretch and seam requirements.

Overlock Sewing

Overlock machines are widely used for joining knitted fabric panels and controlling raw seam edges. Suitable three-thread, four-thread or five-thread configurations may be selected according to the operation and garment construction.

Coverstitch Sewing

Coverstitch machines are commonly used for T-shirt hems, sleeve hems and other knitwear finishing operations requiring stretch-compatible stitching. Two-needle and three-needle arrangements may be used according to the approved specification.

Flatseam and Flatlock Construction

Specialized flatseam equipment can produce relatively flat seams for suitable garments. Flatlock construction should not be confused with ordinary overlock stitching or decorative coverstitching.

Feed-Off-the-Arm Sewing

Feed-off-the-arm machines are used for selected tubular or enclosed seam operations where the machine configuration supports efficient handling and suitable seam construction.

Bar Tack Reinforcement

Bar tacking provides localized stitch reinforcement at selected stress points, such as pocket openings, drawcord openings or other approved garment details.

Buttonhole and Button Attachment

Polo shirts and other buttoned garments may require industrial buttonhole and button-sewing operations. Button position, attachment security and placket appearance must follow the approved technical specification.
