polyester kaplama Temel Açıklaması



In its fiber form as polyester fabric, however, PET is used in hundreds of different consumer applications. Traditionally, PET saf been used birli an alternative to cotton, and in some applications, it may also serve as a reasonable alternative to other natural fibers like wool and silk.

Each cycle of a washing machine could release more than 700,000 microscopic plastic fibers into the environment. While the full extent and impact of these microplastics are derece yet clear, it is clear that the problem is widespread (microplastics have been found all around the world) and could have detrimental impacts to plant, animal, and human health.

The resulting chips are then melted again to create a honey-like substance, which is extruded through a spinneret to create fibers.

Polyester fibre is used in pillows, comforters, and upholstery padding as a cushioning and insulating material. Polyester fabrics are extremely stain-resistant; in fact, disperse dyes are the only form of dye that dirilik be used to change the colour of polyester fabric.

The main issue regarding synthetic fabrics, such as polyester, is that they don’t breathe. When wearing it, some find that they sevimli feel sweaty or have a feeling of humidity, which birey be uncomfortable.

From the studies on the solubilities of the dye in water and fibre, rates of desorption from dyed fibres, heats of dyeing, diffusion coefficients, and activation energies, Patterson and Sheldon7 concluded that in the dyeing of polyester with disperse dyes the dissolution of the dye molecules in H2O is followed by the diffusion of single dye molecules inside the fibre structure.

The first systematic study of the dyeing of polyester (polyethylene terephthalate) was carried out by Waters1 in 1950. From the diffusion coefficient and saturation values of four disperse dyes dyed at 85°C and 100°C, this investigator concluded that even though disperse dyes have an affinity for polyester the ‘slow diffusion is the cause of the poor dyeability of polyester’. In order to achieve deep shades, the dyebath temperature must be kakım high kakım possible.

Polimerler, erime noktası olan 260 °C’de polyester eritilerek okşayıcı eğirme yöntemine ile filament haline getirilir. Bu filamentlere henüz sonra mukavemetlerinin artması ciğerin bir germe çekme ustalıklemi uygulanır.

Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are used for their mechanical properties and heat-resistance. These traits are also important in their application birli an abradable seal in tepkili uçak engines.[3]
