The impact of the raw materials used to make personalized woven labels on the environment is closely related to the type of material. Common raw materials for woven labels include natural fibers (such as cotton and linen), synthetic fibers (such as polyester and nylon) and blended materials. The impact of different materials on the environment during production, use and disposal varies significantly. The following is an analysis of the types of raw materials, environmental impacts at each stage and sustainable improvement directions:
I. Natural fiber woven labels (cotton, linen, etc.)
1. Production stage
Planting stage:
Cotton: Traditional cotton planting requires a lot of water resources (about 2,700 liters of water are needed to produce 1 T-shirt of cotton), and pesticides and fertilizers may be used, leading to soil degradation and reduced biodiversity.
Hemp (such as flax and hemp): Less water is required during the planting process, and hemp does not require pesticides, which is more environmentally friendly.
Processing stage:
Natural fiber processing requires spinning and weaving, which may produce industrial wastewater (such as printing and dyeing wastewater containing dyes and chemical additives), which will pollute the water body if not properly handled.
The processing of organic cotton personalized woven labels prohibits the use of toxic chemicals, wastewater treatment is more stringent, and the environmental load is lower.
2. Use stage
Natural fiber woven labels are skin-friendly and breathable, with moderate washability, and no harmful substances are released under normal use.
3. Disposal stage
Degradability: Natural fibers such as cotton and linen can be decomposed by microorganisms and eventually converted into carbon dioxide and water. If they enter the natural environment (such as soil and ocean), the degradation process is relatively environmentally friendly.
Potential problems: If blended with synthetic fibers (such as cotton + polyester), it may affect the overall degradability and need to be sorted and recycled.
2. Synthetic fiber woven labels (polyester, nylon, etc.)
1. Production stage
Source of raw materials:
Polyester (PET) and nylon are both derived from petrochemical products. The production process consumes a lot of fossil energy and produces greenhouse gases (such as carbon dioxide).
About 60% of the world’s clothing fibers are synthetic fibers, and their production accounts for 3%-4% of global oil consumption.
Processing links:
Synthetic fiber spinning requires a high-temperature melting process, which consumes a lot of energy; the dyeing process may use nitrogen and phosphorus-containing additives, leading to eutrophication of water bodies.
Some factories use liquid coloring technology (dyeing before fiber spinning) to reduce subsequent dyeing wastewater discharge.
2. Use stage
Microplastic risk: During the washing process, synthetic fiber woven labels may release tiny fibers (about 190,000 microplastics are released each time they are washed), which enter the ocean with sewage and enter the food chain after being ingested by organisms.
Durability: Synthetic fiber woven labels are wear-resistant and washable, but after long-term use, the fibers may age and break, forming more microplastics.
3. Discarding stage
Difficulty in degradability: Polyester and nylon take hundreds of years to decompose in the natural environment. If they are landfilled or incinerated, they will release toxic gases (such as dioxins) or occupy land resources.
Recycling challenges: Synthetic fiber woven labels can be recycled through physical recycling (melting and regranulation) or chemical recycling (decomposition into monomers), but the current global textile waste recycling rate is only about 13%, and most are still discarded.
3. Blended material woven labels (cotton + polyester, nylon + linen, etc.)
Environmental impact: Combining the advantages and disadvantages of natural and synthetic fibers, but facing the problem of material separation.
Blended woven labels are difficult to separate natural and synthetic fibers by simple means, resulting in high recycling costs and low efficiency. In most cases, they may be directly incinerated or landfilled.
If the proportion of synthetic fibers in the blending ratio is high (such as 60% polyester + 40% cotton), the overall degradability will be significantly reduced, and the risk of microplastics will increase.
4. Environmental impact of special processes and auxiliary materials
In addition to the basic materials, the post-processing processes and auxiliary materials of woven labels may also increase the environmental burden:
Gold/silver, flocking, reflective materials:
Use chemical adhesives or metal plating, which may contain heavy metals (such as lead, nickel) or VOC (volatile organic compounds), pollute the air during the production process, and are difficult to recycle after disposal.
Dyeing process:
Traditional dyeing uses azo dyes (some of which contain carcinogens). If the wastewater is not treated, it will pollute the water source and harm aquatic life.
Composite materials:
Plastic strips sewn on the edge of woven labels, hot melt adhesives on the back of labels, etc., may increase the pollution problem of mixed materials.
5. Sustainable improvement direction
In order to reduce the negative impact of woven label raw materials on the environment, the following measures can be taken:
1. Material substitution
Promote recycled synthetic fibers:
Use recycled polyester (rPET) (made from recycled waste plastic bottles), which reduces energy consumption and carbon emissions by 30% – 50% compared to virgin polyester.
Case: Patagonia and other brands have adopted 100% recycled polyester woven labels.
Organic natural fibers:
Choose organic cotton (chemical pesticides are prohibited during the planting process), hemp fiber (drought-resistant, no pesticides required) or bamboo fiber (fast-growing, renewable).
Certification standards: GOTS (Global Organic Textile Standard) and OCS (Organic Content Standard) can ensure the environmental friendliness of raw materials.
2. Process optimization
Waterless dyeing technology:
Use supercritical carbon dioxide dyeing or digital printing to reduce more than 90% of dyeing water.
Single material design:
Ensure that the personalized woven label is consistent with the main material of the clothing (such as pure cotton clothing with pure cotton woven label) to facilitate overall recycling or degradation.
Simplify post-processing:
Avoid unnecessary hot stamping, flocking and other processes, and give priority to environmentally friendly inks (such as water-based inks) and adhesives (such as bio-based glue).
3. Circular economy model
Recycling system construction:
Brands establish recycling channels for personalized woven labels and achieve material circulation through physical or chemical recycling technologies (such as H&M’s “old clothes recycling program” covers textiles including labels).
Degradable design:
Develop bio-based synthetic fibers (such as polylactic acid PLA), whose raw materials come from plant starch and can be completely degraded under composting conditions after disposal.
FAQ
The environmental impact depends largely on the source and end-of-life disposal. Natural fibers like cotton and linen are biodegradable and break down into carbon dioxide and water, though traditional cotton cultivation requires significant water and pesticides. Synthetic fibers like polyester and nylon are derived from petrochemicals and take hundreds of years to decompose; they also carry a risk of releasing microplastics during washing cycles.
Brands can improve sustainability by switching to recycled synthetic fibers, such as rPET (made from recycled plastic bottles), or by choosing organic natural fibers like organic cotton or hemp. Additionally, adopting “single material design”—ensuring the label is made of the same material as the garment—facilitates easier recycling and degradation, while using eco-friendly water-based inks and avoiding unnecessary chemical post-processing further reduces the environmental burden.
