Custom Hoodie Manufacturing Process: From Tech Pack to Bulk Production

Custom Hoodie Manufacturing involves much more than adding a logo to a blank garment. For a true cut-and-sew project, the fit, fabric, construction, decoration, trims, washing process and packaging need to be developed as one complete production system.

At Minghang Garments, development can begin with a tech pack, reference sample, sketch or clear product brief. From there, we move through fabric selection, pattern making, sampling, pre-production confirmation, cutting, sewing, finishing and quality control before bulk production.

1. Define the Hoodie Specification

Our Custom Hoodie Manufacturing Process begins with a tech pack or a detailed brief that includes the appearance, fit and functionality of the hoodie. Reference images are useful for communicating design direction, but production also requires measurable specifications such as garment dimensions, fabric requirements, construction details, artwork placement and tolerances.

Essential specifications include:

•Pullover, zip-up, oversized, cropped or performance silhouette

•Fabric composition, target GSM and surface finish

•Garment measurements and acceptable tolerances

•Hood shape, lining and drawcord construction

•Kangaroo, welt or zippered pocket design

•Rib composition, height and stretch recovery

•Zipper, eyelet, cord end and other trim specifications

•Artwork size, color, position and application method

•Main label, care label, hangtag and packing requirements

Decision	Technical Information Required	Risk If Unclear
Fit	Size chart, grading rules and points of measure	Inconsistent sizing
Fabric	Composition, GSM, finish and color standard	Wrong hand feel or shrinkage
Construction	Seams, pockets, hood and reinforcement	Weak or distorted garment
Decoration	Artwork file, dimensions and placement	Incorrect scale or alignment
Packaging	Folding, labels and carton ratio	Repacking and delivery delays

At this stage, Minghang's design and product-development team reviews manufacturability, prepares patterns or technical details where required, and identifies elements that could increase cost or complicate production.

2. Select and Test the Fabric

There are many attributes that make up a piece of fabric. Some of those attributes include how the fabric drapes, how warm the fabric is, how tough the fabric is, how the fabric holds up when washed, and what kind of finishes the fabric has. One way to measure fabric is by GSM (grams per square meter), but that doesn't really tell you the full story about the quality of the fabric.

Some standard options for development are:

Fabric Type	Typical Use	Key Control Points
French Terry	Lightweight and Transitional Hoodies	Loop Quality, Spirality, Shrinkage
Brushed Fleece	Warm Lifestyle and Streetwear	Pilling, Shedding, Surface Consistency
Cotton-Polyester Blend	Teamwear and Everyday Use Hoodies	Blend Ratio, Colorfastness, Stability
Performance Polyester	Training and Sports Hoodies	Moisture Management, Stretch/Recovery, Heat-Setting and Print Compatibility
Heavyweight Cotton	Premium Streetwear	Shrinkage, Seam Bulk, Drying Time

Prior to cutting, suitable tests may include:

•Fabric Weight and Useable Width

•Dimensional Stability After Washing

•Colorfastness To Washing and Rubbing

•Pilling and Abrasion Resistance

•Fabric Skew or Spirality

•Stretch and Recovery of Rib Components

•Shade Consistency Between Rolls

Some knitted fabrics require relaxation or preshrinking before cutting. If the fabric is spread under excessive tension or cut before it has fully relaxed, the panels may change dimension, twist or lose alignment after washing. Skew and spirality should therefore be checked before bulk cutting. At Minghang Garments, all fabrics pass our incoming materials inspection are conducted with pre-shrinking process before cutting.

3. Develop the Pattern and Approve Samples

Once the technical drawing is finalized, the pattern maker can create the panel pieces that will be used in production. There are a few things the pattern maker has to consider when making panel pieces: the balance between the body, sleeves and hood, seam allowance, how much the fabric will shrink, and the stretch of the fabric.

Depending on the complexity of the project, sampling may include:

• Development Sample Used to check design and basic construction

• Fit Sample Used to check balance, silhouette and measurements

• Size-set Sample Used to check grading across sizes

• Pre-production Sample Used to check fabric, trim, color, and branding

• Approved / Golden Sample used as the physical reference for bulk production

Comments at Minghang Garments are recorded by measurement point and construction area. Examples like “make it looser” need to be translated to specific modifications, for example, increasing the half-chest width by 2 cm, or adjusting the depth of the hood by 1.5 cm, for instance.

Bulk cutting will not be done prior to the approval of the pre-production details.

4. Prepare, Cut and Bundle the Fabric

Once the fabric, pattern and pre-production details are confirmed, bulk production moves into the cutting room.

The production team performs the following steps:

• Inspects the fabric and separates shade lots

• Performs relaxation or preshrinking as needed

• Plans markers to optimize fabric usage

• Controls the grain of the fabric during spreading

• Performs cutting of panels which are then numbered and size bundled

• Performs notching and placement marking for assembly

Panels must not be bundled together across different dye lots in a single garment. Bundling correctly ensures that panels arrive on the sewing line in the correct color and size.

5. Printing or Embroidery

The method of decoration should be selected according to the fabric type, order volume, washability, and the effect desired.

Method	Best Application	Main Production Consideration
Screen printing	Bold graphics and larger production runs	Color separation, curing and ink coverage
DTG printing	Detailed multicolor artwork	Pretreatment and cotton content
Embroidery	Logos and premium branding	Stitch density, backing and fabric distortion
Heat transfer	Names, numbers and short-run graphics	Temperature, pressure and adhesion
Sublimation	Polyester panels and all-over graphics	Fabric composition and panel alignment

When artwork crosses panels or requires precise placement before seams are closed, printing or embroidery may be completed on cut panels before assembly. Other graphics can be applied after sewing, depending on placement, equipment and the planned wash or finishing sequence.

At Minghang, the decoration method is selected according to the artwork, fabric, wash process, order quantity and the customer's target appearance.

6. Sew and Assemble the Hoodie

During assembly, operators join the shoulder seams, sleeves, hood, body panels and pockets according to the approved construction specification. For zip-up hoodies, additional attention is required to maintain zipper alignment, front-panel symmetry and hem balance.

The most important parts of the construction are:

•Finishing pocket corners and zipper ends

•Placement of a hood and drawcords

•Rib tension in cuffs and hem

•Flat, secure seams without puckering or skipped stitches

•Coverstitch or topstitch of even width

•Correct label position and orientation

The machine, needle and thread used should be appropriate to the fabric. A heavy needle can ruin a lightweight knit fabric and the seam can pull apart with use.

7. Control Quality From Production to Packing

The Custom Hoodie Manufacturing Process consists of many steps, such as the procurement of materials, pre-production, and inspections which are conducted inline and upon completion. Minghang implements a 5+1 quality-control system to evaluate the product at multiple stages of the production process and upon completion.

Some of the key checkpoints are:

•Comparisons of actual measurements to approved tolerances

•Stitch density and seam security and symmetry

•Alignments of the hood, pockets, ribs and zippers

•Logo: correct dimensions, color and placement

•Shade: uniformity and defects in the fabric

•Curing of the print or the transfer adhesion

•Labels, quantity, folding and packaging

•Wash testing where required by the fabric, finishing process or buyer specification

The approved sample, tech pack and purchase-order should be the production inspection references.

8. Understand Cost and Lead-Time Variables

Pricing is not solely determined by the quantity ordered. The Custom Hoodie Manufacturing Process is affected by:

• Stock fabric versus custom-developed material

• Number of colors, sizes and fabric dye lots

• Pattern complexity and sewing operations

• Print area, color count or embroidery stitch count

• Custom zippers, labels, ribbing and packaging

• Testing and inspection requirements

• Number of sample revisions

• Freight method and delivery destination

A professional manufacturer should explain these cost drivers and confirm the production route before bulk manufacturing begins.
