Description
Technical field
The present invention relates to a kind of preparation methods of imitative goose down shape heat insulating material, belong to non-woven material technical field.
Background technology
Pursuit with people to " healthy living ", each state all are being dedicated to developing on material of people's health without influence
Material.It is traditional take, the heat preservation heat insulating material such as home textile, footwear, it is always barely satisfactory in warming and comfort balance.In the presence of
It the various moisture absorptions, easily go mouldy, the disadvantage of easy hardened, easy allergy and feel difference.As the improvement of people's living standards, people should
It asks clothes to meet outside traditional function of cold, more focuses on the decorative beauty of clothes, it is desirable that clothes fashion is novel, dress is beautiful, generous
It is proper, it is comfortable and easy to wear, and clothing function is considered comprehensively, if clothes total quality is light and handy, good hand touch is non-stimulated, to environment without dirt
Dye.In addition with the expansion of mankind's activity range and the needs of environment, heat preservation heat insulating material is required not only be used as and be kept out
Extraneous cold gas ensures human body basic life requirement and physiological function, to be also used for field tent, military combat clothes, step on
Mountain is equipped and the related fields such as automobile, aerospace.
In traditional heat insulating material, the warming effect of natural feather is best.It is influenced by bird flu event, for the warming material of tradition
Expect for natural feather, though having good warming effect, since it derives from birds, various countries is caused to become dark to the attitude of natural feather
It is dark unknown.Easily hardened for traditional heat insulating material moisture absorption, the problems such as easily going mouldy, bore suede, in addition people more tend to frivolous
High-efficiency thermal protection material.These have all promoted various countries to march toward in the research of down-like heat insulating material.
Down-like product（Especially imitative goose down）With market potential, existing down-like product fineness exists substantially
1.5dtex.But imitative goose down production difficulty is big, the requirement to fineness is relatively high, and product fineness will control substantially
1.2dtex can be only achieved imitative goose down effect, and common process is difficult to meet the regeneration superfine denier polyester production requirement of serialization.But
Terylene superbhort fiber is mostly to be spinned after being processed into slice using virgin materials at present, and production cost is higher；Also have using useless
Old PET（That is polyethylene terephthalate）The polyester block that is generated in bottle piece, sheet material, film and polyester material production process,
The regenerative PETs material such as waste silk is that raw material is produced, and to reduce cost, realizes resource reutilization.But due to the regenerative PET of recycling
Expect that quality is irregular, the polyester slice that intrinsic viscosity and fusing point are processed with virgin materials has very big difference, also contains
There are more non-polyester plastics impurity and moisture, causes spinning quality adversely effected, obtained finished fiber appearance, feel etc.
There are larger gaps compared with real natural feather for performance.
And limited by process conditions, there is also fibre finenesses and fluffy degree to be difficult to reach imitative goose down effect in production process
Fruit, fiber level of stretch not enough uniformly, the shearing length of easy fracture when stretching, fiber less it is uniform it is accurate, be also easy to produce overlength
And the shortcomings of over-length fibre.
Invention content
The technical problems to be solved by the invention：Imitative goose down effect, fiber level of stretch for existing anti-goose down material
Easy fracture when not enough uniformly, stretching, fiber shearing length less it is uniform it is accurate, be also easy to produce asking for overlength and over-length fibre
Topic, provides a kind of preparation method of imitative goose down shape heat insulating material.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of preparation method of imitative goose down shape heat insulating material, specific preparation process are：
（1）Bombax cotton, terylene short fiber, willow Down Fiber, microwave treatment after washing are taken, and is matched by multilayer tiling mixing
Mixed dispensing is sent into shredding in opener, by lapping after carding machine cards at single layer web by material；
（2）It takes polyamide elastomer, polylactic acid to add twin-screw extrude 5~8min of melt blending, then squeezes out injection melt-blown
In equipment, it is used in combination filter assemblies to intercept and filter impurity, obtains melt；
（3）Melt is sprayed through spinneret, and attenuating draws and attenuates until fracture, forms the ultra-fine of disordered arrangements under thermal current drawing-off
Fiber, and the single layer web surface on the defeated lace curtaining of melt-blowing equipment is fallen, it is formed and imitates goose down shape heat insulating material.
Step（1）The bombax cotton, terylene short fiber, willow Down Fiber parts by weight be 60~75 parts of bombax cottons, 20
~25 parts of terylene short fibers, 80~100 parts of willow Down Fibers.
Step（1）The single layer web grammes per square metre is 80~120g/m2。
Step（2）The polyamide elastomer, polylactic acid parts by weight be 80~100 parts of polyamide elastomers, 80~100
Part polylactic acid.
Step（2）The melt blending process is 5~8min of melt blending at 180~210 DEG C, and control screw speed is
30~40r/min.
Step（2）The extrusion temperature is 190~200 DEG C, and the strainer temperature is 190~200 DEG C.
Step（3）The spinneret temperature is 200~210 DEG C, and the thermal current is 220~230 DEG C of temperature, pressure 0.12
The thermal current of~0.15MPa.
Step（3）A diameter of 2~5 μm of the superfine fibre.
Step（3）The defeated lace curtaining rotating speed is 6.0~6.4m/min, and it is 25~35cm to receive distance.
Compared with other methods, advantageous effects are the present invention：
（1）The present invention is longitudinally cylinder using bombax cotton, willow Down Fiber, and surface is smooth, it is soft and rich in gloss, it is transversal
Face is round or oval, hollow, shows the big hollow design feature of thin-walled, and tiling to mix by multilayer carries out dispensing, opens
Networking is combed after pine, degree of hollowness height is made, and fineness is thinner, and wicking is apparent, and the moisture equilibrium at dry side time is short, and leads wet fast, fibre
Adipocere matter is contained in dimension table face, has anti-wetting property, the good single layer web of the fluffy performance and elastic recovery properties of fiber, then make
Meltblown fibers become entangled on fibre web, and to form suede branch and small suede branch structure, bombax cotton, willow Down Fiber are formd similar in
Empty suede branch, plays a supporting role, and increase the air content inside melt-blown material, improves the warmth retention property of melt-blown material
Energy；
（2）The present invention is using fibre web as branch, and melt-blown micro fibre is the Down-like Material of small suede branch, and it is fine to be meltblown Down-like Material
Dimension is finer and close, and hole is small, and surface energy is big, forms the structure with air bag effect, is conducive to reduce material surface and inside is empty
The flowing of gas, to improve warming effect, and heat insulating material keeps material finer and close because of its fine fibrous structure, and material table
There are a large amount of thin down in face, similar lotus leaf, to show water repellent effect, and fiber finer and aperture it is small, cannot allow hydrone
Pass through, but vapor can pass through.
