Description
[technical field]
The utility model relates to the ptt fiber field, specifically, is a kind of nano-negative ion powder PTT doughnut.
[background technology]
Along with improving constantly of living standards of the people, people are not only attractive in appearance, endurable to the requirement of dress ornament, but more and more pay attention to comfortableness.Heteromorphosis and functionalization are the focuses of current chemical fibre development.The clothes that the various fibres in differentiation that continued to bring out are in recent years made more and more are subjected to consumer's favor.And the exploitation of the thin antibiotic ptt fiber of dawn hollow has been complied with above-mentioned trend just and has been launched.
Bamboo wood is the important forest reserves of China, and its growth is fast, can become a useful person in a short time, and power of regeneration is strong, once afforests successfully, sustainable felling utilization.Bamboo wood was mainly used to make aspects such as farm implements, fuel, furniture, commodity, handicraft, construction material, floor and papermaking in the past, and value is low.
Along with science and technology development, domestic employing bamboo is fired bamboo charcoal, has enlarged its Application Areas greatly.Because bamboo charcoal nano has special structure, its molecular structure is hexagon, the carbonaceous densification, than great, hole is many, content of mineral substances is abundant, contain the material to the human body beneficial such as potassium, magnesium, iron, manganese, calcium, zirconium, and specific area is big, have stronger adsorption capacity, antibiotic, smelly, the moisture absorption of disappearing, drying and good electrical conductivity, uvioresistant.And have far infrared, an anion emission function.
Because the macromolecular conformation of PTT and the lattice conformation of polymer chain, the elongation at break of fiber is greater than all fibres except that spandex.The percentage elongation of PTT is moderate, and its suitable elastic performance is suitable for the requirement of people to elastic fabric.The elastic recovery of PTT is better than PBT, more is better than PET.Compare with the outstanding rigidity of polyster fibre and goods, the feel of ptt fiber and fabric can be given the soft and comfortable sensation that approaches nylon.Add the good drapability and the suitable elasticity of fabric, for the fashion designer provides design inspiration and more wide space of thinking.The synthetic fiber disperse dyeing only just can be dyed dark color more than vitrification point.The vitrification point of PET is about 70～80 ℃, and owing to its degree of crystallinity height, compact structure, dye molecule are difficult for entering fibrous inside.So PET only when pressurizeing or having carrier, temperature to be about 130 ℃, could dye dark color with DISPERSE DYES.And the glass transition temperature of PTT is lower than PET about 46 ℃～65 ℃, so its dyeability is better than PET, can be under DNAcarrier free situation, and boiling dyeing at normal pressure.Simultaneously, under identical dyeing temperature, the length of penetration of dyestuff in PTT is apparently higher than PET, and color and luster is even, the fastness height.So not only can the fuel savings and the energy, can also reduce the content of chemical substance in the sewage simultaneously, the pollution on the environment degree reduces relatively, has tangible economic benefit and environmental benefit.Because these advantages make ptt fiber have bigger development and application prospect than PET fiber.By adjusting suitable spinning process condition and process for cooling condition, make the nano-negative ion powder PTT doughnut product that meets specification requirement.

[specific embodiment]
Be described further below in conjunction with accompanying drawing, simultaneously the embodiment that provided is provided the utility model.
Embodiment 1
Fiber adopts novel nano negative ion powder and PTT section blend, and the mass fraction of nano-negative ion powder is 3%, and model is VK-F12-01, degree of hollowness 83.3%; The external diameter R of hollow shape spinnerets is 0.6mm, and internal diameter is 0.1mm.
This nano-negative ion powder PTT doughnut adopts the spray silk spinnerets of particular design to make by high-speed spinning process.Its process route is: POY-DTY.Spinning speed 2000-3600m/min, fiber produces certain degree of orientation under high-speed winding speed, and the precursor structure is more stable, DTY process velocity 400--700m/min.Be characterized in that technological process is short, the production efficiency height.But the POY long-term storage, long-distance transport, DTY is best in quality, and POY-DTY technology has become the process route that extensively adopt present countries in the world.
The technological design of spinning nano-negative ion powder PTT doughnut mainly should be considered spinning temperature, drying process and cooling condition.Because the adding of nano-negative ion powder makes in the big molecule of fiber and contains inorganic molecules, influences gravitation between high-polymer molecular, thereby influences macromolecular regularity, for the stable state spinning, can suitably reduce spinning temperature.Moisture removal in PTT and the nano-negative ion powder hybrid slicing, also can avoid in spinning process, water entrainment steam in monofilament, produce " cavity filament " and cause lousiness, waft silk or broken end, the irregular phenomenon of stock-dye that also can avoid the difference because of moisture to cause simultaneously.Because the discharge-amount of POY is big, liberated heat is also many, so need the humidity of the wind speed of cooling quench and wind higher, wind-warm syndrome is lower.
Certainly, we need be according to the manufacturing condition of reality, and when going wrong, we will in time adjust every technological parameter, to reach best properties of product.
