A kind of three-dimensional（3D）The preparation method of upright cotton sound-absorbing sound-insulating and heat-insulating non-woven cloth, including following steps, under
Face will be further described as follows：
The technological process of preparation：Choose raw material → determine mixed proportion and weigh weight → shredding → mixing → combing → baking oven →
It batches
The three-dimensional upright cotton sound-absorbing sound-insulating and heat-insulating non-woven cloth → performance test analysis of processing.
1）The technological process of production is as follows：
Bale opener → cotton blender machine → conveyer belt → pre-blowing machine → fine opener → air pressure cotton box → pre-comb machine（It is according to circumstances
No use）→ carding machine → molding machine → folding cotton machine → baking oven → coiling system → finished product
2）The key technology of the non-woven sound-absorbing sound and thermal insulating material of the three-dimensional upright cotton of processing is as follows：
It is to mix different fibers to mix from the purpose of shredding, and mixed and disorderly coma or fiber block are then loosened into fibre bundle.
Convenient for the progress of rear road carding step.It is required that be uniformly mixed, shredding it is abundant, while reducing the damage of fiber to the greatest extent.By mixing
After shredding, the abundant shredding mixing of fiber can be made, uniform fibre is obtained after so that it is further combed on carding machine
Net is tieed up, for smoothly strong condition is created in production in next step.
The first step after raw material is carried out shredding, mixing, after being processed by pre-blowing machine, then feeds fine opener → comb
Reason machine.
There is electronic scale bale-reopening machine opener uniformly, quantitatively to feed, and more compound uses can mix different fibres in proportion
Dimension, automatic control and adjustment range is big, accurate using different fibre furnish, is uniformly mixed.1000 ~ 1500mm of breadth, to cotton amount 30 ~
60 kgs/hour, weighing bucket volume 0.43m3, open 1 ~ 2.5 beat/min of number of bucket.
Cotton blender machine carries out fully free-and-easy accumulation by the raw material proportioning of preliminary shredding, by rotating public attention effect, then by skew nailing
Curtain carries out section crawl, reaches most effective immixture, and a certain amount of storage cotton can make production line keep continuous production.Breadth
1800-2200mm。
Second step, the technological parameter and key technology of opener process：
Shredding feeds the technological parameter and key technology of process：Select rational opening process and technological parameter, shredding speed
It is appropriate, cannot be excessive or too small, the purpose of shredding is not achieved when too small, fiber is easy to damage when excessive, generates staple fiber, shadow
Ring the quality of final products.Speed wants moderate selection, reduces the damage to fiber, and raw material, can be under the premise of abundant shredding
Ensure to be uniformly mixed.
Raw material is carried out mixing shredding by pre-blowing machine using FL-P10-120 types, FL-P10-150 types, using goat's horn tooth,
Fibre damage can be reduced.It is suitable for after carrying out preliminary shredding and mixing to fiber, next procedure is delivered to by wind turbine.According to fibre
The type and characteristic of dimension determine Openability, generally 800 ~ 1200 kgs/hour, 1200 ~ 1500mmm of working width, cylinder
Structure has the characteristics that big metal sawtooth, aluminium alloy steel nail card wire plate, with feeding is balanced, Openability is big, fibre damage is few
The characteristics of.
Fine opener uses FL-J10-120, FL-J10-150 type：Fine opener is by preceding working procedure by preliminary loose
Composite fibre carry out further fully after shredding.Reach combing to require, and next process is transported to by cotton transport blower fan.Root
According to the type and characteristic of fiber, Openability, generally 600 ~ 1000 kgs/hour are determined, 1200 ~ 1500mmm of working width,
Cylinder construction has the characteristics that big triangle sawtooth, aluminium alloy steel nail card wire plate, equipment have exhaust cotton receiving box, dust Control, open
The feature that fine effect is good, fibre damage is few.
Third walks, the technological parameter and key technology of carding step：Speed, gauge etc. are reasonably selected when combing, excluded
Impurity, staple fiber and cotton knot reduce the damage to fiber, and reduce short fiber index makes fiber be rendered as single fiber by combing effect
Dimension state, it is ensured that be uniformly mixed, gauge appropriate is avoided that web became uneven is even, it is possible to reduce generate clouding net, rotten net
With the probability to score a goal, the quantity and fiber net surface density irregularity rate of cotton knot are reduced.Point comb of carding machine, uniformly mixes all removal of impurities
Close with the interactively of rack, metallic card clothing plays the performance of carding machine and the carding quality of non-woven cloth fiber key
Effect.The specification of reasonable selection metallic card clothing is wanted in production.
The technological parameter of carding machine：W1202 type carding machines, main cylinder rotating speed are less than 237r/min, and breast cylinder rotating speed is less than
389r/min, upper and lower doffer hasten to be less than 123r/min, and feeding roller rotating speed is less than 0-8r/min, goes out lace curtaining rotating speed and be less than
343r/min, pattern doffing roller rotating speed are less than 268r/min, and feed roll motor rotating speed is less than 8r/min, main technique gauge：
1 main technique gauge of table
4th step processes the non-woven sound-absorbing sound and thermal insulating material of three-dimensional upright cotton using hot blast adhesion equipment baking oven, the process
Technological parameter and key technology：
Hot wind, which reinforces key process parameter, to be had：Tack temperature, heat air pressure and wind velocity etc..Technological parameter will be according to raw material spy
Property, product requirement etc. are configured, and whether process parameters design rationally has direct influence to properties of product and quality.
The key process parameter that hot wind is reinforced includes mainly hot blast temperature, hot wind wind pressure, speed of production.Due to hot blast temperature
The softening melting temperature of heated plastic fiber influences.When the temperature increases, product strength will increase, otherwise can decline, but hot wind
Temperature is no more than critical value.Fiber percent thermal shrinkage can otherwise increased, the flexibility of product is caused to decline.Wind pressure and fiber
Grammes per square metre and thickness are to wanting consistent, to ensure that hot wind can smoothly penetrate web.Wind pressure wants moderate, cannot be excessively high, otherwise can destroy
The structure of fibre web.Cause web net irregularity to increase, influences the total quality of final products.Speed of production will according to it is quantitative,
The technological parameters such as thickness determine, cannot be too small or excessive, otherwise directly affect the heated time of web and being heated evenly property
Deng to ensure good fiber net structure, it is desirable that have abundant and enough heated time, to change life in the actual production process
When producing speed, it is necessary to it is corresponding to change hot blast temperature and hot wind wind pressure etc., to ensure that the total quality of web is stablized.
The beneficial effects of the invention are as follows：The non-woven sound-absorbing sound-insulating and heat-insulating material of three-dimensional upright cotton of the fiber process of the present invention
Material, is a kind of feature of environmental protection noise reduction, sound-absorbing, acoustic material, but also is a kind of noise reduction of new type functional, sound-absorbing, acoustic material,
It has good sound-absorbing, sound insulation, heat insulation with many apertures, micropore, hole and gap etc..
