Hemp requires very little water and birey produce up to twice bey much fiber per hectare as cotton. It also grows organically extremely well, eliminating the need for chemical pesticides and fertilizers. Hemp is biodegradable, breathable, renewable, and feels similar to linen to wear.
Thermally stable polymers, which generally have a high proportion of aromatic structures, are also called high-performance plastics. This application-oriented classification compares such polymers with engineering plastics and commodity plastics. The continuous service temperature of high-performance plastics is generally stated bey being higher than 150 °C,[12] whereas engineering plastics (such bey polyamide or polycarbonate) are often defined bey thermoplastics that retain their properties above 100 °C.
The reaction was also applied successfully to the preparation of highly crystalline and poorly soluble polymers which require high temperatures to be kept in solution (at least until a sufficiently high molecular weight was achieved).[23]
Polyesters bey thermoplastics may change shape after the application of heat. While combustible at high temperatures, polyesters tend to shrink away from flames and self-extinguish upon ignition. Polyester fibers have high tenacity and E-modulus bey well birli low water absorption and minimal shrinkage in comparison with other industrial fibers.
Hobilerinize normal olarak boyanabilir polyester obje de yeğleme edebilecekleriniz ortada mevzi alabilir. Objeler yüzeylerinin konstrüksiyonsı sebebiyle birgani farklı boya ile kolayca boyanabilir.
Leading brands don’t wait for a new sustainable material to be widely available before using it; they invest in research and development and help suppliers bring new materials to market. Some of the companies appearing on Textile Exchange’s leaderboard for polyester were early adopters of recycled materials.

Besides the above-mentioned large processing units to produce staple fiber or yarns, there are ten thousands of small and very small processing plants, so that one güç estimate that polyester is processed ctp kaplama yapan firmalar and recycled in more than 10 000 plants around the globe.
The process of creating polyester fiber begins with reacting ethylene glycol with dimethyl terephthalate at high heat. This reaction results in a monomer, which is then reacted with dimethyl terephthalate again to create a polymer.
In recent decades, however, the harmful environmental impact of this synthetic fiber has come to light in great detail, and the consumer stance on polyester saf changed significantly.

2The thermophysical and mechanical properties of PET greatly depend on its degree of crystallinity. The greater the crystallinity, the harder and stronger the plastic.
