Description

A kind of cross bamboo carbon ptt fiber

[technical field]

The utility model relates to the ptt fiber field, specifically, is a kind of cross bamboo carbon ptt fiber.

[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 cross bamboo carbon ptt fiber 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.Bamboo carbon 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, bamboo carbon; And have bamboo carbon, 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 bamboo carbon ptt fiber product that meets specification requirement.

[utility model content]

Technical problem to be solved in the utility model provides a kind of cross bamboo carbon ptt fiber, with the actual needs that satisfies life and produce.

For realizing above goal of the invention, the technical solution adopted in the utility model is:

A kind of cross bamboo carbon ptt fiber, this fiber adopts PTT new material and bamboo carbon, cuts into slices blend after the cross spinneret melt spinning makes by bamboo carbon and PTT, and the mass fraction of bamboo carbon is 1～10%, and spinnerets is the cross spinnerets;

Described fiber cross section is a cross;

The length-width ratio of described fiber is 6: 1.

The good effect of a kind of cross bamboo of the utility model carbon ptt fiber is:

(1) advanced composite material (ACM) PTT with and the fiber that forms through blend melt spinning of bamboo carbon have good wearing comfort energy and Color;

(2) the special maximum characteristics of cross fibre are that density is little, have the high ventilation wet transmitting performance; And the characteristics of bamboo carbon fibre are the feature of environmental protection and security;

(3) the cross bamboo carbon ptt fiber fabric of final products, the good hand feeling softness, bright in luster beautiful, be full of variety, the performance of fabric obviously is better than ordinary polyester.

[specific embodiment]

Be described further below in conjunction with accompanying drawing, simultaneously the embodiment that provided is provided the utility model.

Embodiment 1

Fiber adopt bamboo carbon and with PTT section blend, the mass fraction of bamboo carbon is 3%; The long a of spinnerets is 1.2mm, and wide b is 0.2mm; This bamboo carbon ptt fiber adopts the 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 bamboo carbon ptt fiber mainly should be considered spinning temperature, drying process and cooling condition.Because the adding of bamboo carbon 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 hybrid slicing also can be avoided 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.

Cross bamboo carbon ptt fiber with preparation 110dtex/48f is an example, utilizes the cross spinnerets.Corresponding to present fiber production apparatus, and for the PTT raw material, the PTT raw material of having selected Du Pont to produce, specific targets are as follows:

Drying equipment: the continuous BM formula of ebullated bed drying machine;

Spinning speed: 3200m/min;

DTY process velocity: 550m/min;

Technological process: PTT hybrid slicing → screening → boiled bed drying → hopper → screw extruder → melt pipe arrangement → spinning manifold → spinneret assembly → lateral blowing cools off → oils → 8 hours → deformation processing → DTY of (POY) → POY balance of reeling;

Component assembling: aluminium packing ring+spinnerets+9 layer net+distribution plate+5 layers of net+sand 80 grams+20 orders sea, 60 orders sea sand 60 gram+individual layer net+flat-rammer+nut;

The condition of cooling quench is: wind speed: 0.45m/s; Wind-warm syndrome: 26 ℃;

Finally spin 1 ton of qualified cross bamboo carbon ptt fiber.
