An introduction to the different types of cotton textiles utilized in DTG applications.

Direct-to-Garment (DTG) printing has gained popularity in the world of custom apparel, offering a seamless solution for creating intricate and colorful designs on various fabrics. One question that often arises is whether you can DTG on cotton. In this article, we will explore the compatibility of DTG printing with cotton, the benefits, and factors to consider, and provide tips for successful DTG printing on cotton garments.

Fabrics are the key to successful direct-to-garment printing. They are comparable to an artist’s canvas; if the canvas is of poor quality, the artist’s work may be ruined. Similarly, it’s crucial to pick the ideal fabric to bring your DTG prints to life and create cozy clothing that withstands wear and tear.

What is Direct-to-Garment (DTG) Printing?

DTG printing is a modern, digital printing method that involves printing a design directly onto a garment using specialized inkjet technology. It’s well-suited for natural fibers like cotton, as water-based inks are used, which are absorbed by the fabric.

DTG Printing Process

The DTG printing process starts with the creation of a digital design, followed by pre-treatment of the garment. The garment is then placed on a platen, and the printer applies the ink directly onto the fabric. Once the printing is complete, the garment is heat-pressed to cure the ink, ensuring a durable and vibrant print.

Types of Textiles

There are three types of fabrics: natural, synthetic, and blends. Let’s take a deeper look because not all cloth kinds are appropriate for DTG printing.

Natural Textiles

These fabrics date back to 1500 BC and are made from natural resources. (e.g. plants or animals). Wool, hemp, cotton, and linen are the most prevalent materials.

Synthetic Textiles

Man-made materials are synthetic fabrics. The first synthetic fiber was nylon, which Carothers created in the 1930s at the DuPont laboratory. Sportswear is typically made of synthetic materials because of its well-known flexibility. Acrylic, Nylon, Polyester, Lycra, and viscose are the most popular materials.

Blends

A mix is a material made of both cotton and synthetic fibers. There are numerous combinations, including cotton/lycra and cotton/polyester. The most well-known blend is poly-blend, a lightweight, wrinkle-free, and breathable fabric made of polyester and cotton. This sturdy yet supple-to-the-touch fabric opens the door to a wide range of uses.

Textiles Suitable for DTG Printing

For intricate patterns with fine details and numerous color nuances, DTG printing is advised. DTG printers employ water-based inks, therefore natural textiles work best because of their propensity to absorb liquids. The result is fibers with very washable colors that are strongly fixed into them. Contrarily, because they are made of plastic, synthetic textiles repel water.

The best textiles for DTG printing include blends, light-colored polyester, cotton, combed cotton, organic cotton, and linen.

Cotton 

Cotton is a renewable resource that may be extracted from the cotton plant. It’s widely used in the textile industry for its breathability, softness, and durability. The majority of cotton is grown in warm climates, particularly in the United States, India, and China.

Cotton is a comfortable, durable, and reasonably priced material. The ease with which this fabric absorbs water-based inks makes DTG printing possible. Undoubtedly, fabrics made entirely of cotton rule. But the consistency of the fabric may also affect your final product. In contrast to thinner materials, thicker materials absorb more ink, resulting in vivid colors and durable prints. There are many different kinds of cotton in general, and the manufacturer may have an impact on the quality. You should select softer, smoother textiles for the best print.

Types of Cotton

Egyptian Cotton

Egyptian cotton is considered the finest cotton due to its extra-long staple fibers. These fibers provide a luxurious, soft, and durable fabric that is highly sought after for high-end bedding and clothing.

Pima Cotton

Pima cotton, also known as Supima cotton, is another high-quality cotton with long staple fibers. Grown primarily in the United States, it’s known for its softness, strength, and color retention.

Upland Cotton

Upland cotton is the most common type of cotton, accounting for around 90% of global cotton production. It has shorter staple fibers, making it less expensive and less soft than Egyptian or Pima cotton. However, it’s still a versatile and popular option for many applications.

Regular Cotton

This sort of cotton is created by taking the fibers and twisting them into yarn, which is then weaved together to create the finished product. Regular cotton is readily available and of poorer quality, making it a favorite among manufacturers of fast fashion.

Organic Cotton

Without the use of synthetic fertilizers or hazardous, long-lasting pesticides, this eco-friendly cotton is grown. Since no poisons are used in this method, the soil’s fertility is preserved. It is regarded as one of the most environmentally friendly options for DTG printing.

Ring-spun Cotton

Cotton fibers are transformed into extraordinarily fine, supple ropes by twisting and thinning the cotton strands. Cotton fabrics that are ring-spun are more breathable, softer, strong, and long-lasting. Since they require more work to produce, they are also more expensive yet deliver a higher-quality result. When printed, they offer a highly smooth surface that produces a clear and vibrant image. Fashion and “boutique” printing are suitable for ring-spun cotton t-shirts.

Combed Cotton

Before being spun into yarn, cotton is “combed,” which means that all of the shorter fibers are removed and all of the fibers are brought into parallel alignment. Combed cotton has a smooth texture and excellent sheen because the short fibers are removed, leaving only the longest, finest strands. The product will last longer since the fibers are stronger and less prone to break because they are longer.

The Importance of Cotton in the Textile Industry

Cotton’s Versatility

Cotton is a highly versatile fabric, used for everything from clothing to home furnishings. Its adaptability makes it a popular choice for various applications.

Cotton’s Breathability

One of the key reasons cotton is so popular is its breathability. It wicks moisture away from the body, making it comfortable to wear and perfect for hot climates.

Cotton’s Durability

Cotton fibers are strong and can withstand multiple washes, making them a durable fabric choice for a variety of products.

Choosing the Right Cotton for DTG Printing

Factors to Consider

When selecting a cotton type for DTG printing, consider the following factors: fiber length, fabric weight, and fabric quality. Longer fibers typically result in a smoother, higher-quality print, while heavier fabrics can better absorb the ink, ensuring a vibrant and long-lasting design.

Recommended Cotton Types for DTG

Both Egyptian and Pima cotton are excellent choices for DTG printing, as they have long fibers and a high-quality finish. Upland cotton can also be used, but it may result in a less smooth print. Organic cotton can be a great option for those looking for an eco-friendly alternative.
