Cotton Thread: The Complete Guide for Wholesale and Manufacturing

Introduction

Among the most popular sewing materials in the world, cotton thread is valued for its natural texture, strength, and smooth sewing performance. For manufacturers, wholesalers, and distributors, understanding cotton thread is essential to choosing the right product for different applications. As a global brand with over 20 years of experience in garment accessories, MH provides a full collection of cotton sewing threads—from fine quilting thread to durable overlock thread. This guide will cover everything about cotton thread, while also introducing related cluster topics such as thread cotton, sew cotton, how is cotton thread made, cotton thread type, cotton overlock thread, and cotton thick thread.

What Is Cotton Sewing Thread?

Cotton thread is spun from natural cotton fiber. It has a soft hand feel, matte appearance, and excellent absorbency, which allows it to hold beautiful dye colors. Certain dyes, such as indigo or iron, can leave residual color or marks left on the cotton thread or fabric, sometimes resulting in visible crocking or subtle color effects. Compared to synthetic threads, cotton is eco-friendly, breathable, and easy to handle for both hand sewing and machine sewing.

How Is Cotton Thread Made?

One of the most common questions we hear is: how is cotton thread made? The process includes:

1. Harvesting & ginning – raw cotton fibers are separated from seeds.

2. Carding & spinning – fibers are combed, aligned, and spun into yarn.

3. Twisting – several yarns are twisted to create sewing-strength thread.

4. Finishing – processes like gassing or mercerizing are applied to improve smoothness and luster.

5. Dyeing – thread is dyed into a wide range of shades for different industries.

MH uses advanced equipment and strict quality control to ensure every spool of cotton thread meets professional standards.
