Abstract
The invention relates to a cottonlike non-woven fabric preparation method. According to weight percentage, 82% of polypropylene raw material, 1% of brightening agent, 2% of softener and 15% of elastomer are mixed and evenly stirred; with heating fusing, plasticizing and mixing via a screw extruder, the mixture is output to a die head via accurate meter of a metering pump; melt bodies evenly go through holes and are extruded into filaments; the filaments are cooled via cooling air and then enter an extractor; with negative pressure, the filaments are absorbed into the extractor and form a cloth surface via auxiliary action of a suction ventilator; and the cloth surface is pre-pressed via sealing rollers, then thermal-bonded via a hot rolling mill and at last solidified to form the non-woven fabric. By the use of the cotton like non-woven fabric preparation method, problems of hardness and harsh feeling of non-woven fabric in the prior art can be solved; demands of cotton soft feeling and fluffy feeling by customers can be met; and great contact dryness and comfortableness can be provided for skin.
Description
Technical field
The invention belongs to textile technology field, be specifically related to a kind of preparation method of imitative cotton nonwoven fabrics.
Background technology
Along with improving constantly of living standard, hygroscopicity that is comfortable, that had and gas permeability are not only worn to the requirement of fabric in market, also pursue fabric sofetening, smooth, elegant style simultaneously.Therefore the comfortableness of textiles is more and more subject to people's attention.The method of current modification mainly contains two kinds of approach: a kind of surface modification of fiber, namely through spray or the fiber lubricant being coated in fabric face, reduces the frictional force between fiber, the drapability of fabric is improved; Another kind in polypropylene, adding other component chemical auxiliary agent or adding other monomer when being polymerized to carry out modification by copolymerization.Chemical modification and physics change flexibility and comfortableness by the refinement of blending and modifying, fiber and two component skin-core structure.Blending and modifying by adding a certain proportion of auxiliary agent class material by screw rod melting mixing extruding spinning in polypropylene GRANULES, changes the color of fiber, feel, gloss and functional requirement by melting mixing.
The SMS composite non woven measuring fiber of current production is the fibre web that continuous print long filament is formed, the fabric face formed is coarse, have hard sense with can tingle or burning sensation during skin contact, can not meet market especially hygienic material product to the requirement of fabric comfort level and pliability.
Summary of the invention
The object of this invention is to provide the preparation method of a kind of comfort level and the good imitative cotton nonwoven fabrics of pliability.
The technical scheme realizing the object of the invention is a kind of preparation method of imitative cotton nonwoven fabrics; By percentage to the quality, the compound of pp material 82%, brightening agent 1%, softener 2%, elastomer 15% is stirred, after screw extruder heating and melting plasticizing mixing, accurate measurement through measuring pump is transported to die head, the uniform via hole wire squeeze of melt, through cooling air cooling laggard enter extension apparatus, silk sucks in extension apparatus under the suction function of extension apparatus, under the booster action of sucktion fan, form cloth cover, the heat bonding process of cloth cover again through hot-rolling mill after the precompressed process of sealed roller is reinforced and is formed nonwoven fabric.
There is into net platform at the vertical lower 30cm place of preferred distance extension apparatus; The melt index of described pp material is 30-40g/10min, and screw extruder temperature is a district 170-190 DEG C, and two district's temperature are 220-230 DEG C, three district's temperature are 225-235 DEG C, four district's temperature are 225-235 DEG C, and five district's temperature are 225-235 DEG C, and six district's temperature are 225-235 DEG C; Die head temperature 225-235 DEG C, measuring pump rotating speed is 45RPM, and cooling air temperature is 2-4 DEG C, and sealed roller temperature is 100-120 DEG C, and the export ratio of sucktion fan is 70%-75%, from extension apparatus lower end to becoming the lapping distance of net platform to be 35-45cm.
There is into net platform at the vertical lower 30cm place of preferred distance extension apparatus; The melt index of described pp material is 30-40g/10min, and screw extruder temperature is a district 170-190 DEG C, and two district's temperature are 220-230 DEG C, three district's temperature are 225-235 DEG C, four district's temperature are 225-235 DEG C, and five district's temperature are 225-235 DEG C, and six district's temperature are 225-235 DEG C; Die head temperature 225-235 DEG C, measuring pump rotating speed is 45RPM, and cooling air temperature is 2-4 DEG C, and sealed roller temperature is 110-130 DEG C, and the export ratio of sucktion fan is 70%-75%, from extension apparatus lower end to becoming the lapping distance of net platform to be 35-45cm; The loading pressure 70-90kg of described hot-rolling mill, flower roll temperature 125-135 DEG C, smooth roll temperature 135-145 DEG C.
The present invention has positive effect: the cotton texture compound nonwoven cloth production technology of this high strength is simple, hard sense and the harsh feeling problem of current nonwoven fabric can be solved, meet the requirement of client to cotton soft feeling and fluffy sense, provide skin better to contact dry feeling and comfort level.
