Jeans Production Process Flow Chart: A Complete Guide

Jeans Production Process Flow Chart: A Complete Guide

  • por {{ author }} Lucy Zhou

Introduction

Ever wondered how your favorite pair of jeans is made — from a roll of denim fabric to a finished, perfectly fitted product?
Understanding the jeans production process flow chart helps reveal the craftsmanship, precision, and technology behind every stitch.

At Newasia Garment Co., Ltd. (INNBLAC), a leading denim manufacturer in China, we specialize in OEM and ODM jeans production for global fashion brands.
With advanced machinery, experienced technicians, and strict quality control, we deliver jeans that meet the highest international standards — trusted by major names like GAP and other global fashion retailers.


History and Evolution of Denim and Jeans

Nowadays, fashion is incomplete without denim. No other fabric has received such wide acceptance in textile history—it's the fabric of generations, worn by all classes and ages. Denim holds an undisputed position in the fashion industry, adapting to trends through unique washing effects.

Originally marketed as workwear for durability, jeans evolved into casual fashion. Techniques like garment washing in rotary drum machines enhanced their appeal. The name 'denim' originates from "serge de Nîmes" in France, while 'jeans' comes from Genoa, Italy. Levi Strauss's copper-riveted overalls in the 19th century founded modern jeans, spreading from American cowboys worldwide.

The future of denim is secure, with growing appeal across ages. It's a symbol of rebellion, independence, and style—a blue magic material that's evergreen.


Denim vs. Jeans: Key Differences

Many think denim and jeans are the same, but they're not. Denim is the rugged cotton twill fabric, woven with indigo-dyed warp and white weft yarns. Jeans are garments (typically pants) made from denim, considered casual wear for men and women.

This article separates the jeans production process flow chart from denim fabric manufacturing for clarity.

Jeans Production Process Flow Chart Overview

The overall jeans production involves two main phases: creating denim fabric and assembling jeans garments. Technological advances have made it fashionable and sustainable.


Denim Fabric Manufacturing Process Flow Chart

Denim is woven and dyed in one location, unlike other cloths. It's similar to grey fabric weaving but dyed during sizing. Cotton is primary, with indigo dyes used.

Step-by-Step Jeans Production Process

Step 1: Fabric Sourcing

Quality Begins with Fabric Innovation

At Newasia Garment, we combine trusted sourcing with independent fabric development to deliver exceptional denim materials. Our fabric selection includes:

  • Premium Sourcing: OEKO-TEX® and ISO-certified materials from established global mills

  • In-House R&D: Self-developed denim fabrics with customized weight, stretch, and performance characteristics

  • Sustainable Options: Organic cotton, recycled fibers, and eco-friendly dyeing processes

  • Technical Specialization: Advanced fabric engineering for specific market needs and brand requirements

This dual approach of selective sourcing and proprietary fabric development ensures perfect material solutions for each client's unique vision and target market.

Step 2: Fabric Inspection

Before cutting, all fabrics undergo 100% visual inspection to check for flaws in color, weave, or texture.
Our automated systems ensure every roll meets client specifications before moving to production.

Step 3: Pattern Making & Sampling

Our in-house design and technical teams use CAD software for digital pattern making.
We create accurate patterns and prototypes based on your designs — adjusting fit, silhouette, and style before bulk production.

Step 4: Fabric Cutting

Using computerized automatic cutting machines, we achieve precision and efficiency with minimal fabric waste.
Each pattern piece is labeled and bundled for seamless assembly during sewing.

Step 5: Sewing & Assembly

This is where craftsmanship meets technology.
Our production lines are equipped with Japanese JUKI and Brother sewing machines.
Each jeans component — pockets, waistband, zipper, and belt loops — is assembled by skilled workers under strict quality control.

Common sewing steps include:

  • Pocket attachment

  • Zipper insertion

  • Waistband stitching

  • Side seam and inseam joining

  • Hem finishing


Step 6: Washing & Treatments

The washing process defines the character of the jeans.
Newasia Garment Co.,Ltd. (INNBLAC)  operates a state-of-the-art washing facility, capable of performing over 20 denim finishing techniques, such as:

  • Stone wash – for a vintage look

  • Enzyme wash – softer texture, less chemical use

  • Acid wash / Sandblast – unique worn effect

  • Laser fading – precise and eco-friendly alternatives

  • Ozone wash – water-saving and sustainable

We use eco-wash technologies that reduce water and energy consumption by up to 50%.

Step 7: Finishing & Detailing

After washing, each pair of jeans undergoes finishing work:

  • Ironing and pressing

  • Adding trims and labels

  • Attaching metal hardware (rivets, buttons, etc.)

  • Final shape correction

Our finishing department ensures every garment looks retail-ready.

Step 8: Quality Control (QC)

Quality is at the heart of everything we do.
Newasia follows a five-step QC system, including:

  1. Fabric inspection

  2. Cutting accuracy check

  3. Inline stitching inspection

  4. Post-wash evaluation

  5. Final measurement & appearance review

We meet AQL 2.5 standards and support third-party inspection from SGS, ITS, or Bureau Veritas.

Step 9: Packaging & Shipping

Finally, jeans are packed according to your brand guidelines — with barcodes, polybags, hangtags, and custom boxes.
We ensure on-time delivery with reliable logistics partners and transparent tracking systems.
Punctual delivery is one of our biggest advantages, earning long-term trust from major brands like GAP.
