PVC Now in fashion Hot degree
I am afraid that other fabrics are incomparable.
In the upper body Actual wear You can't help but sigh:
Originally put a plastic bag on the body
General clothes can also It looks so good.
Especially now the temperature is just right,
Inside jackets and hoodies will make you Dress more interesting!
PVC goes down the T stage
In fact, in the impression about 15 years ago, the clothing made of PVC material began to appear on the T stage. Until this season, it appeared on the T stage in a large area, and it has already gone down the T stage to enter the trend of people's lives. Burberry, Calvin Klein Collection, Gucci, Fendi, even Boss, Hermès have PVC material.

PVC accessories are the most sought-after
The hardest to buy bag list must have a PVC material.
The advantage of this bag is that you can reveal the good things that represent your taste in your bag at one time. If you feel that this is too private, it is very popular to nest a normal bag in a PVC material bag. How to play.
For those street-goers, choosing a PVC handbag is the most appropriate choice nowadays. With such a handbag, you can walk on the leading edge of fashion.
The question is, what is PVC?
PVC (Polyvinyl Chloride), an initiator of vinyl chloride monomers (VCM) in peroxides, azo compounds, etc.; or by free radical polymerization under light and heat Polymerized polymers. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins.
PVC is an amorphous white powder with a low degree of branching, a relative density of about 1.4, a glass transition temperature of 77-90°C, and decomposition starting at about 170°C. The stability to light and heat is poor. Above 100°C or over a long period of time When exposed to sunlight, it will decompose to generate hydrogen chloride, and further autocatalytic decomposition, causing discoloration, physical and mechanical properties also rapidly decline, in the practical application of stabilizers must be added to improve the stability of heat and light.
The industrial production of PVC generally has a molecular weight of 50,000 to 110,000. It has a large polydispersity. The molecular weight increases with decreasing polymerization temperature. Without a fixed melting point, it softens at 80 to 85°C and becomes viscoelastic at 130°C. , 160 ~ 180 °C began to change into a viscous flow state; has good mechanical properties, tensile strength of about 60MPa, impact strength of 5 ~ 10kJ/m2; has excellent dielectric properties.
PVC used to be the most versatile plastic in the world with a wide range of applications. In construction materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wire and cable, packaging film, bottles, foaming materials, sealing materials, fiber Other aspects are widely used.
On October 27, 2017, the preliminary list of carcinogens released by the International Agency for Research on Cancer (IAC) of the World Health Organization (WHO) was published in the list of three categories of carcinogens.
PVC was first discovered in 1835 by a famous French scientist (Henri Victor Regnault). Later in 1872 another German scientist (Eugen Baumann) discovered this new material. At that time, the pvc material was a white solid, It is fragile and has no practical application. At the beginning of the 20th century, Russian chemists (Ivan Ostromislensky) and Fritz Klatte and other chemists all tried to change the fragility of pvc, making it a commercial product but all failed. And ended.
Until 1926, Waldo Semon (BF Goodrich) of the United States synthesized PVC and applied for a patent in the United States. He solved the fragility of pvc by synthesizing various additives and increased the expansibility of pvc material products. The basis of product commercialization.
In 1931 Germany started to use PVC to produce PVC.
In 1941, the United States began to use floating method to produce PVC. As a result, related products of PVC materials began to be used in a large number of production and life applications. With the continuous development of science and technology, the current PVC production and synthesis has been replaced by the ontology synthesis method, making it more efficient and cost-effective. Also greatly reduced.
As for the prospect of PVC, it seems that not only does it have a say in the construction sheet industry, but it also mixes in the fashion industry.
