Greenhouse effect is a warming of Earth’s surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air. Of those gases, known as greenhouse gases, water vapour has the largest effect.
Human activities contribute to global warming by increasing the greenhouse effect. The greenhouse effect happens when certain gases—known as greenhouse gases—collect in Earth’s atmosphere. These gases, which occur naturally in the atmosphere, include carbon dioxide, methane, nitrogen oxide, and fluorinated gases sometimes known as chlorofluorocarbons (CFCs).
Greenhouse gases let the sun’s light shine onto Earth’s surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth’s climate comfortable. Without it, surface temperatures would be cooler by about 33 degrees Celsius (60 degrees Fahrenheit), and many life forms would freeze.
Since the Industrial Revolution in the late 1700s and early 1800s, people have been releasing large quantities of greenhouse gases into the atmosphere. That amount has skyrocketed in the past century. Greenhouse gas emissions increased 70 percent between 1970 and 2004. Emissions of carbon dioxide, the most important greenhouse gas, rose by about 80 percent during that time. The amount of carbon dioxide in the atmosphere today far exceeds the natural range seen over the last 650,000 years.
All of these human activities add greenhouse gases to the atmosphere, trapping more heat than usual and contributing to global warming. Source: www.nationalgeographic.org
Greenhouse gas is any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect. Carbon dioxide, methane, and water vapour are the most important greenhouse gases. (To a lesser extent, surface-level ozone, nitrous oxides, and fluorinated gases also trap infrared radiation.) Greenhouse gases have a profound effect on the energy budget of the Earth system despite making up only a fraction of all atmospheric gases. Concentrations of greenhouse gases have varied substantially during Earth’s history, and these variations have driven substantial climate changes at a wide range of timescales. In general, greenhouse gas concentrations have been particularly high during warm periods and low during cold periods. Source: www.britannica.com
Carbon Neutral - or Net Zero Carbon - is a term used to describe the state of an entity where the carbon emissions caused by them have been balanced out by funding an equivalent amount of carbon savings elsewhere in the world. Such entity can be a company, a service, a product, an event or even a process.
Those savings are created through helping to fund renewable energy projects and energy efficiency projects. Many of those projects bring additional social and community benefits as well as help to reduce greenhouse gases.
Tracking the recycled content in textile products is becoming more and more necessary and possible. People want to know for sure whether or not a material is recycled or a fabric contain recycled component. There are normally two ways to verify o identify that. One way is by system of certification such as Global Recycled Standard or GRS. Final product is traced back to their origins through systematic auditing and documentation from raw material, yarn spinning, fabric manufacturing to finishing. The second way is to add a tracing material or labelling agent in the raw material and later on test to find out the agent in the final product. Take rPET fabric as example. A tracking chemical is put in the raw PET pellets and the chemical can be detected in final fabric product through a chemical analysis.
Pre-consumer textiles are by-products of yarn and fabric manufacture, for example, the thrown away cuttings of the fabrics from the cutting tables of a garment factory, leftovers after all orders are made, or textile materials which have been rejected owing to quality problems. Those materials have not reached consumers. Pre-consumer materials can be recycled. However, they are not the major task of recycling industry because they are usually low in volume. Post-consumer textiles include garments, vehicle upholstery, towels, bedding, purses, and more. They are finished products that have been purchased and used by consumers. Most of the post-consumer textile materials are landfilled, incinerated or just left around in our environment. Post-consumer textile materials are huge in volume and increase day by day. Still a very little portion of them have been recycled in any way and they are becoming a huge environmental challenge for human beings and they are the major area that human recycling efforts and resources should focus on.
RPET织物是一种环保的混纺织物。RPET代表回收聚对苯二甲酸乙烯，换句话说，回收PET或RPET。可再生布是由回收的塑料瓶和棉花或其他合成或天然纤维制成的。RPET织物共混物有不同的混合比，50/50、60/40、70/30等。 关于塑料废物和RPET纺织品的一些事实： 每年有510亿个塑料瓶进入垃圾填埋场。 垃圾填埋场的塑料瓶需要700年才开始分解 回收1吨RPET容器可节省7.4立方码的垃圾填埋空间 RPET织物的碳足迹比有机棉低50% 在购买RPET服装时，您可以放心，它是可回收材料。如果没有这个过程或没有将塑料瓶变成织物，回收的塑料瓶最终会被扔在垃圾填埋场的某个地方。为客户提供可回收的服装是我们感到非常自豪的事情，您也会感到非常自豪!
GRS is the abbreviation of Global Recycled Stand. GRS is a voluntary product standard for tracking and verifying the content of recycled materials in a final product. The standard applies to the full supply chain and addresses traceability, environmental principles, social requirements, chemical content and labeling. The GRS covers processing, manufacturing, packaging, labeling, trading and distribution of all products made with a minimum of 20% recycled material. It also sets requirements for third-party certification of recycled content, chain of custody, social and environmental practices, and chemical restrictions.
再生织物比传统织物更精致，所以使用温和的清洁方法很重要。 1.用冷水清洗，使用温和的洗涤剂，以避免损坏纤维。 2.避免使用漂白剂或织物柔软剂，它们会随着时间的推移破坏纤维。 3.许多回收的织物可以风干，以避免在烘干机中收缩或损坏。 4.储存在阴凉干燥处，避免阳光直射。
