Have you ever met: just bought a printed T-shirt, curtains, etc., washed two or three times on the dark off? Spend effort to select the printed fabrics, because the washing faded lost value, which is the common trouble of consumers and businesses. In fact, the printing fabric washing fading is not accidental, not just a quality problem, the core and fabric color fastness, printing process, washing method related. We will dismantle the truth, analyze the causes, and provide manufacturer-level solutions to help you avoid the color fading pit.

What Does “Color Fading” Really Mean in Printed Fabrics?

Many people refer to color fading when they see the color of a print lighten, but at a professional level, there are many different scenarios, and the core differentiator is the color fastness of the fabric. Color fastness is the textile color to washing, friction, light and other external effects of resistance, is a measure of the quality of printed fabrics, core indicators, directly determines its durability, aesthetics and qualified or not.

We often say fading, in fact, is divided into 3 different situations, many people will be confused, today a one-time clear:

1. Fading: Refers to the intensity of the print color itself decreases, the color becomes lighter, lose luster, but will not pollute other clothing, the core reason is that the dye molecules and fabric fibers of the binding force decreased, resulting in the loss of dyes. For example, red prints become pink after washing, which is typical of fading.
2. Bleeding: The color from the printing area to other parts of the fabric, or contamination of other clothing with the wash, such as black printing after washing, white fabric base was dyed grey, which is not simply fading, but poor stability of the dyes, solid color is not in place to lead to the migration of the color, the essence of the color fastness is also not up to standard.
3. Dullness: The printing itself is not obvious color loss, but the color becomes dark, lose the sense of transparency, this is usually because the dye does not fully penetrate into the fibers, only attached to the surface, after washing the surface dyes are flushed, revealing undyed fibers, resulting in visual darkness, mostly in low-cost printing fabrics.

It must be emphasized here, that is, fabric color fastness is the core of the solution to the fading of the printing wash. Whether it is fading, bleeding or dark, the essence of the color fastness is not up to standard, and the color fastness of the high and low, directly by the quality of the dyes, printing process, color-fixing treatment and other aspects of the decision, which is the core difference between the professional manufacturers and small workshops fabrics.

The Science Behind Fabric Color Fading

Many people wonder why some prints are still colorful after dozens of washes, while others look completely different after one or two washes. In fact, the essence of color fading is that the bond between the dye and the fabric fibers is destroyed, specifically from two core perspectives to understand, after reading, you will understand why some fabrics are washable and some are not.

Dye-Fiber bond breakdown

The essence of printing is to let the dye molecules attached or bonded to the fabric fibers, high-quality printing dyes will form a stable chemical bond with the fiber, while low-quality printing dyes simply attached to the surface, the bond is very weak. When washed, the impact of water, detergent, friction and high temperature will destroy the bond, causing it to break and fall off, resulting in dye loss and color fading, the weaker the bond, the faster the color fades, which is the core reason for the difference in washability of similar fabrics.

Surface vs.Penetration printing

Different printing process determines whether the dye can penetrate into the fiber, which is also the key difference in fading speed.

• Surface Printing: The dye only adheres to the surface of the fabric fibers and does not form a chemical bond with the fibers, but only stays on the surface. This kind of printing is low cost and short duration, but when washing, the pigment on the surface is easily washed away, and the color fading speed is very fast, especially after repeated friction, and even the pattern will come off.
• Penetration printing: The dyes will penetrate into the fiber through chemical reaction and form stable covalent bonds with fiber molecules, which is equivalent to the dyes being incorporated into the fiber itself instead of staying on the surface. The dyes in this type of printing will not be easily washed away by water, and are highly resistant to washing, so the colors will remain vivid even after repeated washing.

Top Reasons Why Printed Fabric Colors Fade After Washing

Combined with our many years of production experience and feedback from a large number of customers, the causes of fabric color fading are mainly concentrated in 7 aspects, covering the whole process of production, technology, use, etc., of which there are 3 reasons that 90% of the people ignore, and they are especially worth paying attention to.

Low-quality dyes or inks

Dyes and inks are the soul of printing, and the core factor that determines the speed of color fading. Small workshops commonly used low-cost industrial dyes, its molecular structure is not stable, poor binding force, may also contain harmful ingredients, easy to wash off and safety hazards. While reactive dyes, disperse dyes and other high-quality dyes, although the cost is high, but the molecular stability, strong binding force, can resist the friction of water washing, from the root to reduce fading, but also in line with environmental safety standards.

Incorrect printing method

Different fabrics and applications require different printing methods. If you choose wrong printing method, even if you use high quality dyestuff, the color will be faded, which is one of the most prominent textile printing problems.

• Pigment printing vs. active printing: Pigment printing is low cost and easy to operate, but the dye only adheres to the surface, poor washing resistance, suitable for short-term use, infrequent washing of the product. Active printing dyes penetrate into the fibers, strong washing resistance, suitable for clothing, home textiles and other products that require repeated washing, especially for cotton, hemp and other natural fiber fabrics, which is the core difference between the two processes.
• Heat sublimation printing: Only suitable for polyester fabrics or high proportion of polyester blended fabrics, if used on cotton fabrics, the dyes can not be combined with the fibers, and the color will fade instantly after washing. Even for polyester fabrics, if the proportion of polyester is insufficient (less than 70%), there will be fading and blurring of patterns.
• Digital thermal transfer: Apopular printing process in recent years, the advantage is clear pattern details, strong compatibility, can be adapted to cotton, polyester, blended fabrics and other fabrics. However, the key to fading lies in the curing process, if the curing is not in place, the pattern adhesion is poor, it is easy to peel off after washing, fading, which is also one of the most common quality pain points of DTF printing.

Poor fixation or curing process

Many people think that printing is enough as long as the dyestuff is good and the process is right, but in fact, the curing process is the last line of defense, and it is also the most easily ignored link. We have found that more than 90% of the fading problems in printing are due to insufficient curing.

The core role of color curing is to allow the dye to fully combine with the fabric fibers, locking the dye molecules and preventing loss during washing. Activated printing, DTF printing, heat sublimation printing, etc. all require strict control of curing temperature, time and pressure. Too low temperature and insufficient time will lead to poor fixation of dyestuff and easy color fading in washing. Too high a temperature and too long a time will damage the fabric fibers, resulting in brittle fabrics and cracked patterns, affecting durability.

Fabric type and structure

The material and structure of the fabric itself will also have a direct impact on the washability of the print, and the probability and speed of color fading varies greatly from fabric to fabric.

• Natural fibers vs. synthetic fibers: Cotton, hemp, silk and other natural fibers, fiber structure, loose, porous, easy to penetrate the dye, but the binding force is relatively weak, if the solid color is not in place, the probability of fading is higher. Polyester, nylon and other synthetic fibers, the fiber structure is tight, the dye binding force is strong, better washability, especially polyester fabrics, with heat sublimation printing, washability up to dozens of times more than not easy to fade.
• Fabric structure: Rough, loose fabrics such as coarse cotton, knitted fabrics, washing friction coefficient is large, will continue to wear the surface of the print, accelerate the dyes off, fading faster. While delicate, tight fabrics such as poplin, satin, the friction coefficient is small, better protection of the prints, stronger washing resistance.

Washing conditions

Even for high-quality printed fabrics, improper washing will accelerate color fading. This is the most easy to control consumers and businessmen, but also the most easy to ignore the link, many people because of the wrong way of washing, waste of quality fabrics.

• Water temperature is too high: Hot water will open the fabric fibers of the gap, so that the original combination of dye molecules with the fibers are more likely to fall off, loss, especially natural fiber fabrics, water temperature over 30 ℃, fading speed will be significantly accelerated. It is recommended that the washing temperature control at 20-30 ℃, can effectively protect the print.
• Improper detergent: Strong alkaline detergent, detergent containing bleaching ingredients will destroy the bond between dyes and fibers, corrode the dye molecules, resulting in fading and darkening. Especially for color prints, bleach and enzyme-containing detergents should be avoided and neutral or weakly acidic detergents should be chosen.
• Stirring intensity is too high: High-speed stirring and hard scrubbing in the washing machine will increase the friction between fabrics, wear down the printed surface, and accelerate the shedding of dyes. It is recommended to choose the gentle mode of the washing machine and avoid scrubbing the printed parts.

Drying and heat rxposure

Drying after washing, as well as daily exposure to high temperatures, is also an important reason for accelerating the fading of prints, many people wash directly after exposure to the sun, not knowing that this will allow the prints to age quickly.

• High temperature drying: The high temperature of the dryer will destroy the stability of the dye molecules, resulting in the decomposition of the dye, color fading, especially DTF printing, pigment printing, high temperature drying will make the pattern cracking, peeling. It is recommended to dry naturally, avoid using the dryer, and do not use high temperature to iron the printed parts.
• Sun exposure: The ultraviolet rays of the sun will break the chemical bonds of the dye molecules, resulting in the decomposition of the dye, the color becomes lighter and darker, which is the core reason why printed fabrics used outdoors are prone to fading. Even if the active printing is washable, long-term exposure to the sun will accelerate the fading of colors, it is recommended to dry in a ventilated place, avoid direct exposure to the sun.

External factors

In addition to the above six reasons, there are two external factors that are easy to ignore, can also lead to fading of prints, especially for long-term use of the fabric.

• Hard water minerals: Hard water contains a large number of calcium and magnesium ions, washing, these ions will combine with the dye molecules to form insoluble precipitates, attached to the surface of the fabric, will not only make the print dark, but also reduces the combination of dyes and fibers, accelerating fading. It is recommended to wash with soft water or add softener when washing.
• Sweat, friction and repeated washing: Long-term wear of clothing, the acid in the sweat will corrode the dye molecules, destroying the bond. And repeated friction and frequent washing will constantly wear down the print, resulting in a gradual flow of dyes. Even for high quality fabrics, slight color fading will occur after dozens of repeated washings, which is normal, but poor quality fabrics will show obvious color fading in advance.

How to Prevent Printed Fabric from Fading

Aiming at the above fading reasons, HONGTAO from two perspectives, to provide landing solutions, to help you from the production, use of two links, to maximize the avoidance of fading from washing of printed fabrics, to extend the service life of the fabric.

For manufacturers

As a fabric manufacturer, the core of controlling the fading problem is to control the quality from the source, which is also the key for HONGTAO home textile to keep the customer’s reputation for many years, and we mainly do four points:

1. choose high quality dyes and inks: Reject low-cost industrial dyes, give priority to reactive dyes, disperse dyes and other high-quality environmentally friendly dyes, to ensure that the molecular structure of the dyes are stable, and strong bonding with the fibers, and at the same time comply with international environmental standards such as the OEKO-TEX standard, not only to ensure that the washability, but also to protect the safety of the product. 2. match the correct printing process.
2. Match the right printing process: According to the fabric material and customer demand, choose the right printing process. For example, give priority to reactive printing for cotton fabrics, heat sublimation printing for polyester fabrics, and DTF printing for small batch customization, so as to avoid fading problems caused by mismatch between the process and the fabrics.
3. Strictly control the curing process: Equipped with accurate color fixing and curing equipment, according to the type of dyestuff and fabric material, we set the exclusive curing temperature, time and pressure to ensure that the dyestuff and fiber are fully combined. After each batch of fabrics is finished, sampling and testing are carried out to ensure that the color fastness is up to standard before leaving the factory, so as to avoid unqualified products from entering the market.
4. Color fastness test before mass production: Before mass production, we make samples for washing test and rubbing test to check whether the color fastness is up to standard, if there is any fading problem, we will adjust the process and change the dyestuffs in time to avoid batch reworking and reduce the cost, which is one of the core differences between the professional manufacturer and the small workshop.

For end users

For consumers or clothing, home textile business, the correct use and care, can effectively extend the service life of printed fabrics, reduce color fading, mainly do 5 points:

1. Cold water washing: Washing temperature control at 20-30 ℃, avoid hot water, especially the first washing, soak in cold water for 10-15 minutes, gently scrub, can reduce the loss of dyes, the first washing is recommended to wash separately, to avoid bleed color pollution of other clothing.
2. Use mild detergent: Choose neutral or weak acidic detergent, avoid using strong alkaline detergent, bleach, enzyme-containing detergent, don’t pour the detergent directly on the printed part when washing to avoid corrosion of dyes.
3. Reverse side washing and drying: Turn the printed fabrics over on the reverse side to reduce the friction on the printed surface during washing. After washing, dry naturally, avoid sunlight, high temperature drying, after drying, put in a ventilated place, can effectively protect the printing color.
4. Reduce the friction and frequency of washing: Avoid rubbing the printed parts with force, and choose the gentle mode of the washing machine. Reduce unnecessary washing, such as jackets, curtains, etc., can be wiped regularly, without frequent washing, to reduce the wear and tear of dyes.
5. Avoid high temperature ironing: Do not iron the printed parts directly with high temperature, if you need to iron, you can turn the fabric over on the reverse side and iron with low temperature to avoid high temperature destroying the dye molecules, resulting in cracking and fading of the pattern.

How to Test Fabric Color Fastness Before Buying

For apparel brands, home textile merchants, wholesalers, when purchasing printed fabrics, testing color fastness beforehand can effectively avoid fading pits and avoid bulk losses. No professional equipment is needed, you can operate it at home, and you can test it in 3 simple steps:

• Simple water + cloth test: Take a small piece of printed fabric, soak it in cold water for 10-15 minutes, then gently wipe the printed parts with white cotton cloth, observe whether the white cotton cloth is stained, and at the same time, observe whether there is obvious fading of the fabric printing. If the white cotton cloth is stained, or the fabric print is obviously lightened, indicating that the color fastness does not meet the standard, do not recommend purchasing.
• Friction test: White cotton cloth, in the printing part of the repeated friction, dry friction, wet friction 10 times, to observe whether the white cotton cloth is stained, as well as whether the printing part of the wear and tear, discoloration. If the friction of white cotton cloth staining is serious, or printing wear and tear obvious, indicating poor color fastness, easy to fade after washing.
• High-temperature test: Asmall piece of printed fabrics, placed in warm water at about 40 ℃ for 20 minutes, and then gently scrub, and observe whether the print is fading, bleed color. If there is obvious fading, it means that the dye binding force is weak and not suitable for repeated washing.

For wholesalers and importers, in addition to simple tests, you can also ask the fabric manufacturer to provide professional color fastness test reports to ensure that the color fastness of the fabric is up to standard, so as to avoid purchasing poor-quality fabrics, which will affect their own reputation.
