The customization process of underwear is inseparable from pattern printing. Although there are many types of printing, the more popular high-end printing in recent years includes reactive printing and digital printing. Let’s take a look at the reactive printing and digital printing.

Reactive printing, as the name implies, means that our printing dyes are processed by reactive printing and dyeing. Compared with the pigment printing, no azo and formaldehyde are added in the printing process, and it does not contain harmful substances to the human body, and it does not fade when washed.

The difference between reactive printing and pigment printing is that reactive printing feel smooth and soft. The common saying is that reactive printing fabrics look like mercerized cotton, and the printing effects are very good from both sides; while pigment printing fabrics feel stiff, It looks a bit like an ink painting effect.

The design elements of reactive printing are relatively diverse: plants and flowers, geometric figures, English letters and different color blocks are organically combined to express different design styles through design techniques. Such fabrics are suitable for a wide range of groups and can be used for a long time. Reactive printing fabrics are bright in color, good in color fastness, soft to the touch, can be washed frequently without fading, and look like new after long-term use.

Reactive printing is also called reactive dyes. It contains active groups that can react with fiber molecules.In the process of dyeing and printing, the active groups of reactive dyes form a combination with fiber molecules, so that the dyes and fibers form a whole. The fabric has excellent dustproof performance, high cleanliness, and does not fade after long-term washing.

Reactive printing: the use of reactive dyes to penetrate into the fabric to form a print; Pigment printing: use paint to cover the fabric to form a print.

Comparing the two, you will see that there is a big difference!

Generally, reactive printing can ensure environmental protection and harmlessness to people, and the color and fabric feel better, and there will be no hard or soft feeling.

Simply put, reactive printing is relative to pigment printing. The consumables used in reactive printing are called reactive dyes, which have good color fixing rate and lifting power! Reactive printing is a printing process in which the consumables are completely integrated with the fabric after being sprayed by a printing machine, so that the dye and fabric form an integral printing process. Therefore, the fabric after reactive printing has excellent dustproof performance, high cleanliness and high color fastness. Good air permeability and soft hand feeling, but traditional reactive printing also has problems such as cumbersome printing process, long process and difficult processing! So digital direct printing came into being as the most cutting-edge technology of reactive printing!

Digital direct printing technology, without plate making, can directly print the pattern in the computer on the fabric, realizing the printing effect of what you see is what you get. It is easy to operate and completely breaks through the color limitation of traditional screen printing. Digital printing can print 16.7 million colors on the color spectrum. The color is rich, the printed part is breathable, and it is comfortable to wear. After testing, the washing fastness is as high as level 4, and it can be washed repeatedly. Does not fade. Due to the use of water-soluble consumables, it does not contain any chemical components harmful to the human body, so it is environmentally friendly. From a large perspective, it meets the requirements of enterprises to control costs, meets the national requirements for environmentally friendly clothing, and meets the environmental protection standards of importing countries. From the perspective of industry trends, my country’s textile and underwear manufacturing industry is bound to break through the traditional model, from the manufacturing industry with low cost and cheap labor as its main advantage in the past to the one that focuses on research and development, from production efficiency to brand efficiency, and has high added value. Transformation of new manufacturing industry. Correspondingly, the market strategies of some enterprises with high level of management and high-grade products will inevitably change. In pursuit of high added value of products, this kind of marketing must require small batches, multiple varieties, personalization, fast delivery, high quality, short popular cycles of fabric patterns and underwear styles. And this is where the advantages of digital inkjet reactive printing lie.

The above is the relevant content of reactive printing and digital printing, I hope it will be helpful to you.

Method 1 Reactive printing — dye reacts with the fibre, giving good wash fastness on cellulosics
Method 2 Digital printing — pattern applied without a screen, which suits short runs and variants
Screen cost A screen per colour, which is why analogue printing needs volume to justify it
Digital cost No screen, so the barrier is the per-metre price rather than the setup
Where reactive wins Volume designs on cotton and cotton-rich substrates
Where digital wins Small runs, multiple colourways and photographic detail
Substrate constraint The fabric constrains which methods are available, not the other way round
Fastness link The method sets the achievable wash fastness, which is what a claim rests on
Common error Choosing the method before the design or the substrate
Buyer action Confirm the method against design, substrate and fastness together

Buyer checklist

  • Confirm the design first, then the substrate, then the method.
  • Check the run length against the screen cost of analogue printing.
  • Confirm the achievable wash fastness for the chosen method.
  • Check how many colourways the design needs, since each screen is one colour.
  • Confirm the per-metre price against the per-piece consumption.
  • Check the hand-feel after printing rather than before.
  • Confirm the colour-fastness result on the actual construction.
  • Check the care instruction against the print method.
  • Ask for the appearance after washing rather than on a new piece.
  • Compare quotations with the method stated on both sides.

Buyer Questions

MOQ, lead times, certification and trading terms

Reactive printing uses a dye that reacts with the fibre, which gives strong wash fastness on cellulosic substrates and needs a screen per colour. Digital printing applies the pattern without a screen, which suits short runs and detailed designs at a higher per-metre price. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

It depends on the run and the design rather than on the method. Analogue reactive printing suits volume designs on cotton, while digital suits small runs, multiple colourways and photographic detail — so the choice follows the brief rather than a general preference. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Because each colour needs its own screen, and the screens are a one-time cost per design. That cost has to be spread across the run, which is why analogue printing becomes economic at volume and why a small order usually routes to digital instead. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

It depends on the substrate and the ink system rather than on the method name. What matters is the fastness result measured on the actual construction after washing, which is why the test rather than the method is what supports a claim. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

It constrains it. Not every print method is available on every fabric, and the substrate also decides the hand-feel after printing — so design, substrate and method are decided together rather than in sequence. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

With the print method stated on both sides, since a reactive print and a digital print on the same garment are different specifications with different fastness and different cost structures. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
