With the improvement of people’s living standards, traditional solid-color fabrics have no longer been able to meet people’s pursuit of high-quality life. However, you could have a variety of choices in various printing patterns, which greatly enriches people’s material life enjoyment. Do you want to experience a different kind of printed underwear, but you don’t know what kind of printed underwear to choose? Maybe you should know what type of printing is best for underwear.

 

We should have an idea of different types of common prints.

 

1. Transfer Printing

First, the pigment is printed on the paper by the printing method to make transfer printing paper, and then the color is transferred to the fabric through high temperature (heating and pressure on the back of the paper), which is generally used for chemical fiber fabrics, which are characterized by bright colors and fine layers. The pattern is realistic and artistic, but the process is currently only suitable for a few synthetic fibers such as polyester. The transfer printing process is simple, the investment is small, and the production is flexible. It is currently more popular in the market… But to be honest, the price of this transfer printing is a little higher than other printing types, but it has a certain grade.

Transfer printing is generally suitable for boy boxers, boy briefs, and girls brief underwear with partially printed patterns.

2. Discharge Printing

Discharge printing uses dyes that are not resistant to discharge agents to dye the ground color. After drying, print with a color dye printing paste containing discharge agents or both containing discharge agents. It is destroyed and decolorized, forming a white pattern on the color ground or a colored pattern formed by dyeing with color dyes. Also known as pull white or color pull. Can it make it look like the clothes have been washed with water? The color of the clothes seems to have been washed off a lot, mottled. In fact, this is a print. The principle of the print is to pull out the color of the fabric fibers and turn it into another lighter color, as strong as the washing effect, it is a cool print for men’s clothing.

Discharge printing is generally suitable for breathable boxer underwear that is all overprinted.

3. Water Slurry Printing

The so-called water-based slurry is a kind of water-based slurry, which is not strong in the hand feeling and coverage when printed on clothes. It is only suitable for printing on light-colored fabrics. The price is relatively flat, and it belongs to the lower-end printing type. But it also has an advantage, because it will not affect the original texture of the fabric, so it is more suitable for large-area printing patterns. Features Soft feel and bright color, but the major drawback of water slurry is that the color of the water slurry is lighter than the cloth color, and if the cloth color is darker, the water slurry cannot cover it at all. Printing intermediate colors on intermediate-tone fabrics is prone to color collision. For example, printing blue on red fabrics is prone to undesired purples, etc., and printing multi-color water-based slurries are prone to color change.

Water slurry printing is suitable for small floral printing, and the color of the printing pattern needs to be darker than the cloth color of children’s cotton underwear.

4. Plastisol Printing

After the appearance of plastisol printing and its wide application in a water slurry, because of its good coverage, any light color can be printed on dark clothes, and it has a certain gloss and three-dimensional effect, making the underwear look more high-end, so it quickly became popular, and it is used on almost every printed underwear. However, because it has a certain hardness, it is not suitable for large-area solid patterns. It is best to print large-area patterns with water slurry, and then embellish some plastisol printing, which can not only solve the problem of the hardness of large-area plastisol printing but also highlight the pattern. There is also a way to steal a large area of ​​the field pattern to make a rotten effect, but it is always a bit hard to wear, so it is better to combine water and plastisol printing to solve the problem of large-area printing. There are glossy and matte surfaces, soft to the touch, thin and environmentally friendly, and can be stretched. Generally speaking, plastisol printing is more commonly used. Both plastisol printing and water slurry printing can be washed with water.

Plastisol printing is suitable for children underpants with small patterns or logos.

5. Reactive Printing

The type of process that uses the chemical reaction between the active raw material and the fabric to remove the fabric color and replace it with the desired printing color. Advantages: It feels very soft, and the color is bright. It can be divided into white, color, and denim. Disadvantages: Repeated experiments are required according to different fabric components, the operator’s experience requirements are high, the proofing cycle is relatively long, and the cost is high.

Reactive printed fabrics are generally used for comfortable and breathable men’s underwear made of cotton spandex, modal, or bamboo fibers.

6. Hot Stamping and Silvering

After printing with special materials, a novel printing effect of metallic texture is obtained by thermal transfer of anodized aluminum to the clothes. Pros: Looks upscale and shiny. Disadvantages: At present, the quality of bronzing foil is unstable, the high import price is not conducive to small batch production, and the washability is not good. Experienced employees are required to operate the production.

Hot gold hot silver is suitable for the embellishment on the small pattern, which makes the girls brief underwear and cute girly panties look shiny and cute.

Buyer checklist

  • Confirm which method the substrate accepts before approving a pattern.
  • Ask for wash-fastness results on the printed panel.
  • Check the hand-feel against the price tier you are selling into.
  • Confirm the ink chemistry rather than accepting a method name alone.
  • Check the print is covered by the test report for the destination market.
  • Ask how the print ages relative to the body fabric.
  • Confirm the palette the method can achieve before fixing the design.
  • Check the print on a production sample that has been washed.
  • Keep the printed reference sample for the reorder.
  • Review print-related complaints separately from other quality complaints.

Buyer Questions

MOQ, lead times, certification and trading terms

Five dominate: transfer, discharge, water-slurry (pigment), plastisol and reactive. They differ in hand-feel, wash fastness and cost rather than in quality ranking, and the substrate constrains which ones are available — so the method and the fabric are chosen together rather than in sequence. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

It depends on the fabric and the price tier rather than on the method alone. Reactive printing bonds well to cotton; plastisol suits some blends but sits on the surface; discharge removes colour rather than adding it, which limits the palette. The right question is what the substrate accepts. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

It does, and the relevant test is on the printed panel rather than on the base fabric. A garment whose body cloth tests well can still fail on the print, which is why the fastness result belongs to the print specification rather than to the fabric one. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

It changes the scope of the test. The print is part of the tested article, so a report covering only the base fabric does not support a printed garment. Confirm the report names the printed construction you are shipping, for each destination market. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Because some methods sit on the surface of the cloth and others bond into it. Plastisol sits on top, which is detectable in the hand and affects how the print ages; reactive printing bonds with the fibre, which generally gives a softer result. Neither is better in the abstract. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

By method and ink chemistry rather than by a pattern description. Those two, with the substrate and the wash test, explain most of the difference between two quotations that look the same on a mood board — and they are the two items that determine whether the print survives the customer.
