The screening of stalk 1
Producing the stalk non-weaving cloth requires the moisture in the stalk 1 to be not less than 10%, the stalk 1 nature moisture content of results is between the 5%--30%, through drenching with rain, not through being exposed to the sun for a long time, stalk 1 general moisture such as wheat stalk 1, straw weeds are not 10%~15% to stalk 1.Keep certain freshness and keep containing enough moisture in the grass blade stalk 1 the fibrillation operation in 1 fen of promotion stalk, generation hydrogen bonded power between fiber, the intensity of raising product.And: reduce the static that produces in the processing of road, back.So should select not stalk 1 through being exposed to the sun for a long time, do not have through the stalk 1 that drenches with rain or process drenches with rain and suitably teds, one week of harvesting back is the optimal selection material to trimestral wheat straw waste 1, rice straw 1.
The branch fibre of fiber in the stalk 1
Fiber separation being opened, adopted bundle fiber to resolve into filament, is not extraction cellulose wherein.Hemicellulose wherein, lignin do not need to remove, and phase reaction should keep composition wherein as far as possible, was beneficial to form hydrogen bond.Ash in the stalk 1 or other dust composition distribute in process naturally in atmospheric environment, at first the bundle fiber in the stalk 1 are carried out physics and divide fibre.In order to separate the fiber in the stalk 1, use the fine machinery of special branch to carry out the branch fibre of fiber.
Can take dual mode:
Through a careless machine, carry out the branch fibre through a smart machine of dredging again earlier.
Separate fibre through defibrator.The defibrination parameter is: steam pressure 0.5-1.2MPa, preheating time 3~10min.
Fiberate straw 1 is paved into the uniform fibers net.
Between the fiber in the fiber web with suitable mode in conjunction with or be glued together, be formed with the non-weaving cloth of certain intensity.Utilize the hydrogen bond that forms between the fiber, perhaps add binder fiber or adhesive is given fabric intensity.
Hydrogen bonded is the best way.Stalk 1 fiber is a polymer molecule, contains protium, is the necessary condition that hydrogen bond forms.Shorten fiber spacing from, increase the method for the temperature and humidity of fiber in the fiber web, can promote that hydrogen bond forms between fiber.For this reason, earlier by an infrared heater 10, Infrared Heating is by infrared radiation with fiber web, fiber and water resonance are wherein excited, and be a kind of from hot mode, form favourable for hydrogen bond.By a pair of hot roll 11, carry out hot pressing again.Hot pressing can have been shortened the distance between the fiber with the fiber compacting, helps hydrogen bond and forms.General top roll is a steel rider during hot pressing, and lower roll is a rubber rollers.During hot pressing the general 80-135 of fiber web temperature ℃, pressure is at 80-400 newton/mm.
Can in the fiber web after stalk 1 fiber separation, mix binder fiber.Hot-melt adhesive fiber content is 8-25%, is preferably 12%.Binder fiber the best is the low melting point bi-component composite fiber, for example YCTEX Airbond.Low-melting-point composite fiber generally adopts skin-core structure, and general cortex is than low at least 10 ℃ of sandwich layer fusing point.Raw material can be PE/PP, PE/PET etc.YCTEX Airbond cortex fiber is taked new polymer technology, does not need fiber is carried out surface treatment, just with cellulose fibre good bonding force is arranged.Also can adopt bio-based materials to form, can 100% biodegradation, can not produce pollution effect to environment.Binder fiber is under 130-150 ℃ of situation, and its cortex can melt, and is bonded together with cellulose, thereby gives fiber web with certain intensity, forms non-weaving cloth.
Impurity in raw material and the fiber and ash
Stalk 1 fiber self-sow forms, and is subjected to the influence of natural environment can accumulate ash in process of production, is stained with earth, so in the process of producing the stalk non-weaving cloth, should be as far as possible with its removal.In order to deal with problems, the method for employing is: use porose polyester webs 8 in course of conveying, the convey materials of walking upward can be separated part ash, earth, impurity like this from mesh, keeps the purity of raw material.
