- UV resistance:PVC leather is susceptible to UV degradation, especially when exposed to sunlight for long periods of time. Without proper protection, this material may fade or become brittle over time. Manufacturers can overcome this problem by using UV resistant additives or coatings.
- Environmental concerns:As an oh petroleum-based product, PVC leather may have a negative impact on the environment. Although environmentally friendly alternatives to PVC leather exist, the production of traditional PVC leather generates plastic waste and often uses harmful chemical additives. Manufacturers using PVC leather should implement appropriate recycling and waste management measures to mitigate its environmental impacts.
Disadvantages of PU leather for bag manufacturing
- Plastic texture. Pu hiako has a strong plastic texture, and bags made from it will look cheap and low quality. Can’t imitate the glossy feeling of real leather.
- Odor irritation. Because PU leather for petrochemical synthetic materials, PU leather leather odor and leather is very different, PU leather leather smells like plastic or chemicals, while the smell of leather is more natural, almost undetectable.
- Durability. PU leather leather’s durability is not good, it is easy to be pierced or torn. the service life of PU leather is about 1-2 years, when the PU leather leather aging will appear after the phenomenon of peeling, cracking.
- .Air permeability: PU leather leather does not have air holes like leather, it is not permeability. Therefore the pursuit of permeability fabric consumers can give up choosing this fabric.
- Environmental problems:one of the main problems of PU leather is its manufacturing process volatile organic compounds, they are released into the air in the form of gases from some products, including some adhesives used to produce PU leather leather and coatings. These chemicals can cause a range of health problems.
Sustainability and environmental impact of PVC leather as well as PU leather.
The environmental impact of artificial leather has been a hot topic of ongoing discussion in the field of sustainability. As plastic-based materials, the production of PVC leather & Ko te hiako PU e pa ana ki te whakamahinga o nga matū paitini me to ratou tukunga ki te taiao a tawhio noa.
Hiako PVC
- Ko te Polyvinyl Chloride (PVC) ahakoa he iti te utu, he nui te utu o te hanga me te whakakore i te taiao.
- Nga tukunga dioxin: Ko te hanga o te hiako PVC ka tukuna te dioxin, he matū tino paitini e mau tonu ana i roto i te taiao me te whakaemi i roto i te mekameka kai. Kua honohia te Dioxins ki te maha o nga raruraru hauora, tae atu ki te mate pukupuku, nga mate o te punaha mate me nga raruraru whanau.
- Ko nga taapiri kino: Ko nga mea whakahiato penei i te phthalates ka taapirihia hei whakarei ake i te ngawari me te kakano o te hiako PVC. Ko enei taapiri kua hono ki te whakararu o te homoni me nga paanga kino ki te hauora o te tangata.
- Persistent Waste:Like polyurethane, PVC is not biodegradable and can accumulate in landfills, exacerbating the plastic waste crisis. Incinerating PVC releases toxic chemicals into the atmosphere, further polluting the air.
Pu Hiako
- VOC emissions VOCs are a group of chemicals that are released into the air in the form of gases from certain products, including certain adhesives and coatings used in the production of PU leather. These chemicals can cause a range of health problems (headaches, dizziness, and eye, nose, and throat problems).
- Heavy metals: for example lead and cadmium. These metals are toxic to humans and animals, and exposure to high concentrations can cause serious health problems, including nerve and kidney damage and cancer.
- non-biodegradable. PU leather materials are non-biodegradable, but can be recycled to a certain extent. However, the cost of recycling is high, and not all regions have the infrastructure to recycle PU leather. As a result, many PU leather products end up in landfills, where they can take hundreds of years to finally decompose and cause environmental degradation.
Which is better, artificial leather or genuine leather?
Generally speaking PU leather only lasts 1-2 years, PVC leather will last a little longer, but no matter what after that it will show signs of tearing and skin damage. Genuine leather, however, is different and can last a lifetime or more with proper care.
But in terms of cleaning and maintenance, PU leather and PVC leather are much easier.
In terms of ethical and environmental issues, many people will think that killing animals is unethical and avoid genuine leather, but think about it from another angle, is genuine leather really not environmentally friendly. In the case of cowhide, which is widely used and hard-wearing, leather comes from beef cattle that have been bred. This means that the leather industry is actually a by-product of the livestock and beef industries. Utilizing cowhide, which is not loved by the public, actually reduces waste.
I tua atu, ko te mea hiako he mea koiora noa iho, ahakoa me ruku ki etahi matū, kare e tata te pa ki te hiako waihanga.
Whakamutunga
When choosing whether to use PVC or PU leather, it is important to consider their advantages and disadvantages as well as their impact on the environment PVC leather is favored for its durability, versatility, and lower cost, and is particularly suited to applications where water resistance and ease of cleaning are required. However, there are negative environmental impacts associated with its manufacture, such as dioxin emissions and persistent waste issues, which need to be treated with caution. In contrast, while PU leather is more simulated and affordable, it also suffers from environmental issues such as VOC emissions and heavy metal releases, and is less durable.
From a sustainability point of view, leather is relatively more environmentally friendly as a biodegradable material and as a by-product of animal husbandry. Although it requires strict management and handling to avoid environmental pollution, under the right conditions leather is still an option with lasting value and texture.
Therefore, the selection of the right leather material should take into account functional needs, durability, cost, and environmental impact. In practical applications, the recovery and recycling of materials should also be promoted to minimize resource wastage and environmental burden.
