Description
Technical field
The invention belongs to function synthetic fibre technical field, and in particular to a kind of nano-material modified PBT spinning.Background
Technology
It is increasing to textile and clothing and packaging demand as world population constantly increases and growth in the living standard.By
It is growing more intense the problems such as grain and cotton strives ground, natural fiber has been difficult the life requirement for meeting people, and synthetic fibers are in global fiber
Increasing proportion is accounted in consumption.Compared with other composite fibre materials, the versatility of polyester material is higher, has excellent
Physical and mechanical properties, plus cost of material than relatively low, industrialization technology is again very ripe, and single line production capacity is increasing, this
A little factors make polyester（Such as terylene）The application of fiber is more and more extensive, and demand is also continuously increased, polyester fiber yield from
19,700,000 tons in 2000 rise to 34,500,000 tons in 2010, and increasing degree is big.
Material and material are studied and handled with the development of science and technology, nanometer technology may be implemented on nanoscale,
Realize in the new material made of the interior regulation and control substance structure of nanometer scale (1~100nm) with specific performance.Nano material has
The features such as size is small, specific surface area is big, surface energy is high, surface atom ratio is big；With small-size effect, quantum size effect,
The effects such as macro quanta tunnel effect, skin effect；So that people have larger progress in spinning field.
PBT is polybutylene terephthalate (polybutyleneterephthalate fibre) abbreviation, Zeng Shigong
The favourite son of engineering plastics.Japanese Di Ren companies are proposed PBT fibres first within 1979.With the development of fibre in differentiation, PBT
Use value as fiber is just progressively recognized.PBT fibers have following some features：With good durability,
Dimensional stability and preferably elasticity, and elasticity is not affected by humidity.Soft, the moisture absorption of PBT fiber and its products
Property, wearability and fibre crimpn are good, and tensile elasticity and the elasticity of compression are fabulous, and its elastic recovery rate is better than terylene.PBT fibers exist
Special retractility is respectively provided with the conditions of dry and wet state, and elasticity is not influenceed by ambient temperature change, and price is far below
Spandex fibre.With good dyeability, boiling dyeing at normal pressure can be carried out with common disperse dyes, without carrier；After making dyeing
Fiber colour it is bright-coloured, color fastness and chlorine resistance are excellent.With excellent chemical proofing, light resistance and heat resistance.
How to be effectively modified PBT more with nanometer technology is had specific spinning, has important research
