Description
Technical field
The present invention relates to a kind of seaweed polyester fibers and preparation method thereof, belong to fibre technology field.
Background technique
Polyester is as one of three big main force's fibers in synthetic fibers, because its excellent physics and chemical characteristic are answered extensively
For garment material and other non-garment industries.Polyester product since the advent of the world, also Zeng Yiqi drapability is good, intensity is high, very
It includes and all kinds of textiles is weaved as main textile raw material by downstream user.With economic globalization, internationalizationof of market, people
Requirement to clothes is also higher and higher, not only to have comfort, also to have functionality, fabric is just to light, soft, functional
Direction is developed, and composite fibre materials need to be continuously improved performance just to meet requirements of weaving process, and China's polyester industrial is quickly grown, and gathers
Oneself develops to 27,000,000 tons of year ends 2010 from 516.5 ten thousand tons at the beginning of 2000 to ester fiber yield, and average annual growth rate is more than
25%, account for the 66% of global polyester output.
Polyester fiber has become the maximum synthetic fibers kind of yield in chemical fibre, be widely used in clothing, decoration,
The national economy various aspects such as household textiles, fabrics for industrial use and national defence, Industrial Engineering.It 5 years from now on, will also keep fast
Speed increases.But as textile material, polyester fiber also has the shortcomings that obvious.Scientific, efficient, good processing method is selected,
To adaptation and promote the high speed sustainable development morning of polyester fiber most important.
Marine algae extract is a kind of pure natural marine organisms product, inside contains phycocolloid acid, crude protein, multivitamin,
