CVC,TC,PVC,PU,PU,PA的区别

来源:搜索,自己根据市场调研,给出区别,但是还没有形成体系,先放这里.

CVC俗称:涤棉倒比,是的涤棉织物,一般的说法是说棉含量高于涤量,常见的有65%棉,35%涤
T/C指涤多棉少的织物,常见的65%涤,35%棉。
TT纯棉织物

PVC,PU,PA全是化学别名,在纺织织物的涂层中被用到
PU涂层的特点薄而有弹性,最贵
PVC涂层的特点可涂的厚,相对便宜一点,但涂厚了也贵,常见配合压延工艺,用于雨衣箱包等
PA又分水溶型和溶剂型,最便宜的一般涂层

下面是相关的CVC,T/C和T/R的英文全称,其他的全称还没有找到,知道的可以告知下.
CVC:  CHIEF VALUE OF COTTON .
        THE RATE OF COTTON EXCEED 50%, e.g. COMMON RATE:80%COTTON,20%POLYESTER
T/C:    TERYLENE(POLYESTER)/COTTON.
        THE RATE OF COTTON LESS THAN 50%.COMMON RATE: 65% POLYESTER,35 COTTON.
T/R:    TERYLENE(POLYESTER)/RAYON

Recycle PET
这一类面料称之为再生涤纶面料(Recycle PET),主要节省的是石油能源!(因为我们所有的化
纤类衣服均来自于石油的共聚物)!

What are the different characteristics of PVC, PU; PA and PE?

PVC:
Polyvinyl chlofide is a thermoplastic polymer. Polyvinyl chloride(PVC) is unique in its high chlorine and additives (softeners) content,which makes it and environmental poison throughout its life cycle.Vinyl chloride is a known human carcinogen (BUA 1986,1987,1993;Gray et al.2000,Foster 2000,Ema et al.2001, Kavlock et al.2002a,2002b,2002c). PVC releases dioxin and other persistent organic pollutants during its manufacture and disposal and cannot be readly recycled due to it chlorine and additive content.

Workers in PVC production were getting sick (lung and joint problems).This was soon known as the so called VC-disease.

Furthermore,additives are not bound to the plastic and leach out .To make PVC soft, a lot of softeners have to be added. One of the most commmonly used softeners is di-ethylhexyl phthalate(DEHP).Flexible PVC products typically contain 30 to 40 percent DEHP by weight,but that figure can reach 80 percent in applications where flexibility is critical.DEHP is known to be hormone disrupting ,and otherwise health damaging(Ema et al. 1993,1994,1998;Shiota et al. 1980;) Shiota und Nishimura 1982; Kavlock et al.2002). This is especially true for children and genital organs.It was abandoned by the USA and EU last years,but only for children toys ,and only in these Countries. No one knows what softeners are used in the PVC that is produced and used in products imported from China, for example.

PU:

Polyurethane (PU) is mainly usec in insulation and soft/foamed products like carpet underlay.It uses several hazardous intermediates and creates numerous hazardous by-products.These include phosgene,isocyanates,toluene,diamines,and the ozneddepleting gases methylene chloride and CFCs,as well as halogenated flame retardants and pigments.The burning of PU release numerous hazardous chemicals such as isocyanates,carbon dioxide,hydrogen cyanide,PAH and dioxins.

PE:

Polyolefins such as Polyethylene (PE) are simpler polymer structures that do not need plasticizers,although they do use additives such as UV and heat stabilizers.The polyolefins pose fewer risks and have the hightest potential for  mechanical  recycling. Both PE and PP are versatile ,and can be designed to replace almost  all PVC applications. PE can be made either hard,or very flexible, wihtout the use of plasticizers.

In comparison with PVC,Pe uses fewer problematic additives,has reduced leaching potential in landfills, reduced potential for dioxin formation during  buring (PE burns completely into CO2 and H2O ) and reduced technical problems and costs during recycling.
