The slurry of modern starching includes main slurry and auxilliary slurry, and main slurry has starch type and polyvinyl alcohol type again, and wherein main slurry belongs to macromolecular compound.Their molecular structure must have and the same or analogous functional group of fiber, to fiber good adhesiveness should be arranged, so claim sticker again.Between the big molecule of main slurry certain autohesion must be arranged, its solution can be formed with the film of certain mechanical strength and extension property after drying.In addition, main slurry also should contain a certain amount of hydrophilic radical, so that be modulated into slurries.Main slurry commonly used has starch, animal glue, carboxymethyl cellulose, polyvinyl alcohol and acrylic copolymer etc.Starch: be one of traditional main slurry, commonly used have food starch such as wheat, potato, maize, sweet potato, long-grained nonglutinous rice, cassava, wherein better with maize and wheaten starch sizing performance, can be used for the warp sizing of thin number highly dense cotton.Non-food starch such as rubber benevolence starch also can be used as sizing agent.Starch expands with the temperature rising in water, the gelatinization pulping, and temperature reduces the back and forms gel.Starch slurry is only after gelatinization and be higher than gelling temp and just be suitable for starching.Starch slurry is mobile poor, and viscosity is stable inadequately, and serous coat is crisp hard, be prone to by microbial attack and corruption, so auxilliary slurries such as necessary adapted softener, surfactant, starch distintegrant and preservative agent.Starch contains the volume hydroxyl, and fibers such as the cotton that has the volume hydroxyl equally, fiber crops, viscose glue are had good adhesion.Has mechanical performance preferably behind the farinaceous size drying and forming-film.Various starch derivatives, as contain oxidized starch, water soluble starch ether (like CMS), the starch ester (like starch acetate) of carboxyl, and cationic starch, graft starch etc. are widely used in the starching of various yarns.Animal glue: from bone, tendon, skin or other connective tissues of animal, extract, belong to the albuminoid proteinoid, combine by each seed amino acid.Commonly used have two kinds in gelatine and a gelatin, is applicable to starchings such as natural silk, viscose.Animal glue slurries impregnability is poor, and serous coat is crisp hard, is prone to auxilliary slurries such as corrupt, palpus adapted grease, surfactant and preservative agent.Algin: extensively being present in the various algae, is the natural high polymer that the beta-D-mannuronic acid polycondensation forms.Alginic acid through chemical process makes is water insoluble, and its sodium (or ammonium) salt water soluble is called sodium alginate (ammonium), and its aqueous solution has low concentration, high viscosity characteristic, and the slurry of can deciding separately is used for cotton yarn, spun rayon starching.Cellulose derivative: mainly be water-soluble cellulose ether, that commonly used is carboxymethyl cellulose (CMC).CMC is formed with the monochloroacetic acid etherificate by alkali cellulose, when substitution value greater than 0.4 the time, be water-soluble.Industrial CMC generally is the sodium salt of carboxymethyl cellulose, is applicable to cotton yarn, spun rayon starching.The CMC aqueous solution has low concentration, high viscosity characteristic, and impregnability is poor, good hygroscopicity, and emulsifying ability is strong, with other main slurries good compatibility is arranged.The semifinished product salt content is high, and is strong to parts corrosivity, is inappropriate for sizing.Another kind of cellulose derivative commonly used is hydroxyethylcellulose (HEC), and sizing performance is similar with CMC.Polyvinyl alcohol: the high molecular weight water soluble polymer that gets by the polyvinyl acetate alcoholysis.Polyvinyl alcohol (PVA) commonly used can be divided into two kinds of high polymerization degree and low polymerization degrees by degree of polymerization difference.The former is applicable to staple fibre yarn, and the latter is applicable to the synthetic fiber filament starching.PVA can be divided into two kinds on complete alcoholysis type and partial alcoholysis type by the alcoholysis degree difference.The former is applicable to hydrophilic fibre, and the latter is applicable to the hydrophobic fibre starching.The PVA serous coat is tough and tensile, and high resilience is best a kind of in the existing slurry.It also can with other main slurries with the miscible use of mixing ratio widely, to obtain good starch finishing effect.Its major defect is: slurries bubble, skinning, and the synthetic fiber adhesion strong to hydrophobicity is lower.Acrylic copolymer: mainly refer to be the copolymer and the polyacrylamide of main body with the acrylic acid ester.Component is complicated and changeable, can produce according to purposes.Mostly be viscous liquid, solid content is between 10～40%.Originally polyacrylic acid and its esters slurry are used for the POLYAMIDE YARNS starching, and normal later on and starch is mixed for the starching of synthetic fiber blended yarn.The polyacrylate slurry has good adhesiveness to polyster fibre, can be used for the polyester filament starching.If the hydrogen on the alpha-carbon atom is replaced by methyl, promptly become the polymethacrylic acid slurry.Carboxyl by amide groups (CONH2) replace polyacrylamide (PAAm), belong to nonionic polarity slurry, be applicable to the warp sizing of thin number highly dense COTTON FABRIC.The common feature of this type slurry is good to the synthetic fiber adhesiveness, the low and extension at break of film phonograph strength big (polyacrylamide exception, its film phonograph strength is high, extension at break is little), and moisture absorption, viscosity is strong again.Can not be used for the staple fibre yarn starching separately, should use with PVA or starch.Suitably select set of dispense than to control its hygroscopicity and viscosity again, it is fine to be used for the synthetic fiber filament starch finishing effect.What can be used as main slurry also has: the copolymer of polyoxyethylene, polyvinylpyrrolidone, polyvinyl methyl ethermaleic anhydride and other types.
Auxilliary slurry mainly contains softener, surfactant, starch distintegrant, preservative agent and wax etc. in its aliphatic acid sweet.Softener: can promote the serous coat pliability, the dynamic load when weaving so as to bearing.Commonly used have tallow, suet, a cottonseed wet goods, all is senior grease.Wherein be best suited for sizing with tallow.Surfactant: the material that can significantly reduce surface tension of liquid.Main anionic and the nonionic surface active agent of using, the impregnability that can promote slurries also has effects such as the static of elimination and emulsification.The starch distintegrant: acid, alkali, oxidant and enzyme all can be used as distintegrant the glucoside key in the starch polymer are done appropriate hydrolysis, to promote the flowability of slurries.Sodium metasilicate is the alkaline distintegrant of using always, also can use oxidation Decomposition agent such as toluene-sodium-sulfonchloramide, clorox.Acid and the less use of enzyme.Preservative agent: can suppress microorganism and in slurries or on the gauze, breed, in case slurries are rotten, sizing or fabric are mouldy.Natural slurries such as starch, algin and animal glue often need the adapted preservative agent.Preservative agent commonly used has alpha-Naphthol, is light red brown flakey solid, can be dissolved in alkali lye, but can not add slurries simultaneously with oxidizer containing chlorine, in order to avoid effective chlorine and alpha-Naphthol generation addition reaction and weaken oxygenolysis.Wax: be mainly used in the synthetic fiber starching.Wax as auxilliary slurry should be able to melt in the time of 50～60 ℃ and at room temperature solidify.Wax generally needs to be applied to the sizing surface through emulsification with the after waxing mode, to promote its flatness and to reduce electrostatic accumulation.Mainly contain paraffin (mixture of higher alkane is difficult to emulsification, the destarch difficulty), the beeswax (ester that higher fatty acids and high alcohol are formed; Destarch is also difficult) and the synthetic wax (copolymer of ether type or ester type; Like APEO, better with the compatibility of fiber, also be prone to destarch) three kinds.Paraffin and beeswax should not be used for the fabric of needs printing and dyeing processing.
The processing of also need sizing mixing of modified PVA type slurry, the main apparatus of sizing mixing is the mixing cirtern that has agitator.In bucket, put into earlier the water that is slightly less than scheduled volume when sizing mixing, slowly drop into various slurries by the regulation order and stir, with being steam heated to uniform temperature, adding water adjustment concentration, and adjust its viscosity and pH value, the stock tank (or recycle slurry case) of transporting to Sizing machines through pipeline is subsequent use.
Here twist with the fingers glass fiber yarn to 20 and carry out the starching processing mainly through following equipment realization, pedestal: place the warp beam of defined amount, the warp thread radical of drawing is generally confirmed according to the total radical of fabric warp thread.Stock tank: the container and the add-on component of (insulation) slurries that store, heat.Warp thread is walked around submergence roller adsorption slurry, again through sizing roller be surrounded by between the squeezing roller on elasticity top layer and be squeezed, makes slurries penetrate in the yarn and presses and remove surplus slurry, the rate of sizing that obtains stipulating.The baking storehouse: the device of oven dry wet pulp yarn is divided into three types of drying cylinder formula, hot air type and hot blast drying cylinder association types.Headstock: comprise mechanisms such as main transmission, after waxing device, yarn-distributing rod, survey long dozen seal, expansion reed, beam winding, last doff.Main transmission requires the range of infinitely variable speeds of broad, and creep speed is arranged, and handles the requirement of fault to adapt to not stop.Lease rod is divided into several layers with the sizing of oven dry.Fine and closely woven layer or chemical fibre sizing can be coated micro-emulsifying wax through the after waxing device, make the sizing surface smoothing and reduce electrostatic accumulation.Sizing after the layering further separates through expansion reed, after drag pick-up roll around last beam of a loom.Beam winding mechanism can make sizing tension keep constant under the different speed of a motor vehicle with under the cumulative situation of beam winding diameter.
B, some is carried out and treated through the warp thread of axle, be merged into the warp thread piece of weaving the requirement of required total warp thread radical, form the beam of a loom of certain fabric width and length through batching apparatus;
C, will pass through and 20 twisting with the fingers glass fiber yarns and send into air-jet loom machine and weave after treatment, and form 20 and twist with the fingers the glass fibre grey cloths;
D, twist with the fingers the glass fibre grey cloths carrying out the preparatory destarch of continous mode on the destarch unit in advance with above-mentioned 20, in hot destarch stove, carry out a batch elevated temperature heat destarch again, remove 20 and twist with the fingers the organic ink on glass fibre grey cloths surface;
E, will pass through 20 after the elevated temperature heat destarch and twist with the fingers the glass fibre grey cloths and be immersed in the dipping silane coupling agent; Twist with the fingers the glass fibre grey cloth to 20 and carry out coupling processing; Make the resin in glass fabric and the slurries carry out coupling, open fine the processing in advance and can also twist with the fingers the glass fibre grey cloth to 20 simultaneously.
F, through hydraulic nozzle to above-mentioned 20 twist with the fingers the glass fibre grey cloths cloth cover carry out water and open fine the processing, obtain finished product.
More than be that concrete technological process of the present invention is specified; To have now below and adopt the single fiber diameter is 9um; Single bundle fiber monofilament number is 400 to be twisted with the fingers to be the Z direction through twisting, and the twist is that to weave the 7628 P series glass cloth that form be 9um with employing single fiber diameter to 28 glass fiber yarns (being called for short " undertwisted yarn ") twisted with the fingers; Single bundle fiber monofilament number is 400 process twisting; Sth. made by twisting is to being the Z direction, and the twist is that the glass fabrics of 20 woven 7628 series of glass fiber yarn (being called for short " ultralow twist yarn ") compare according to detecting data, and the result is following:
1, come into operation ultralow twist yarn is produced the air consumption that glass cloth can reduce air-jet loom, practices thrift cost.
Table-1 ultralow twist yarn and the contrast of undertwisted yarn raw yarn Performance Detection:
| Test item | Ultralow sth. made by twisting | Low twist |
| Number number tex | 68.7 | 68.7 |
| Moisture content % | ＜0.3 | ＜0.3 |
| Sizing agent adhesive rate % | 0.8-1.5 | 0.7-1.3 |
| Outward appearance filoplume number (root) | 5 | 5 |
| Stiffness | 40-70 | 50-90 |
| The twist | 18-22 | 25-31 |
Can find out that from above table-1 data the stiffness of ultralow twist yarn raw yarn is a little low than undertwisted yarn, and the sizing agent adhesive rate is high than undertwisted yarn.
The stiffness of the sizing agent adhesive rate and the back yarn of twisting thread is closely related on weft yarn flight property and the raw yarn; Judge that on air-jet loom the good and bad index of weft yarn flight property is exactly to see the size of the arrival deviation of weft yarn, more little its weft yarn flying quality of the arrival deviation of weft yarn is just good more.Table the-2nd, the weft yarn in each stage of ultralow twist yarn and undertwisted yarn arrive the deviation contrast.
The weft yarn in each stage of table-2 ultralow twist yarns and undertwisted yarn arrives the deviation contrast.
To recently seeing, the weft yarn of ultralow twist yarn arrives deviation, and to arrive deviation than the weft yarn of undertwisted yarn little from table-2 data, and this weft yarn flight property that ultralow twist yarn is described is better than the weft yarn flight property of undertwisted yarn.
Main jet pressure contrast table under the different loom speed conditions of table-3 ultralow twist yarns with undertwisted yarn
| The loom rotating speed | Weft yarn | Main jet pressure kgf | Weft yarn | Main jet pressure kgf |
| 560RPM | Low twist | 2.5-2.8 | Ultralow sth. made by twisting | 2.1-2.5 |
| 610RPM | Low twist | 2.5-3.0 | Ultralow sth. made by twisting | 2.1-2.5 |
| 700RPM | Low twist | 3.0-4.0 | Ultralow sth. made by twisting | 2.8-3.5 |
The data of table-3 show that ultralow twist yarn is low than the main jet pressure of undertwisted yarn.
The ultralow twist yarn twist is less, and its stiffness is low than undertwisted yarn, under the condition of the high speed wefting insertion of air-jet loom; The weft yarn flight property that stiffness is low is higher than the high weft yarn of stiffness, and high its needed main and auxiliary jet pressure of weft yarn flight property reduces accordingly, shown in table-3; Under the different loom speed conditions; The main jet pressure of the ultralow twist yarn all main jet pressure than undertwisted yarn is lower, because the high speed wefting insertion of air-jet loom, its air consumption is bigger; Concerning air-jet loom, gas consumption accounts for sizable ratio in whole energy consumption.Adopt ultralow twist yarn can reduce wefting insertion air pressure, reduce its air consumption, this produces potential for the performance loom, energy savings, and comprehensive benefit is weaved in raising has very important meaning.
From main jet pressure measured value table-3, the main jet pressure of the main jet pressure ratio undertwisted yarn of ultralow twist yarn requires less.Reduce air pressure, can reduce pneumatics energy consumption 8%-12% on the one hand, on the other hand, to the also corresponding reduction of the loss of loom nozzle.
2, the glass cloth that ultralow twist yarn produces that comes into operation can reach the resin penetration property that improves glass cloth
The yarn of same line density, yarn twist is more little, and the cohesive force in its yarn between the filament is less; The ultralow twist yarn twist is low, and the tightness degree of low its fabric of yarn twist also reduces accordingly, and its institute's glass cloth of knitting is little than the low twist gauze through, weft yarn gap; Carry out degree of depth shredding through the fine equipment of opening of post processing to warp, the weft yarn of low twist gauze this moment again; Convexity through weft yarn overlapping position is obviously reduced, and the space dwindles or is inaccessible, ventilative also corresponding the reducing of glass cloth; Glass cloth cloth cover is more level and smooth, soft, thereby improves the resin penetration property of CCL with glass cloth.Can judge the resin penetration property of glass cloth through the air penetrability that detects glass cloth, low more its permeability of air penetrability is good more.
The grey cloth of table-4 ultralow twist yarn cloth and low twist gauze is relatively ventilative
Table-5 finished fabrics are opened fine relatively ventilative in advance
Table-6 finished product water distributions are opened fine relatively ventilative
The powerful value of table-7 finished fabric tensions relatively
Hundred meters fault contrasts of table-8 finished fabrics check
Wherein hundred meters faults are meant that fault is on average detained on per hundred meters cloth lengths and count.
To recently seeing, the grey cloth of ultralow twist yarn, opening fibre, water in advance, to open the ventilative value of fine each operation all little and even than the low twist gauze from ventilative tables of data 4.5.6.Ultralow twist yarn open fine cloth ventilative little than the common cloth of undertwisted yarn; Ultralow twist yarn water is opened the air penetrability of fine cloth and is opened the ventilative 20%-30% that reduced of fine cloth than undertwisted yarn; Draw water that the ultralow twist yarn that comes into operation produces thus and open the ventilative minimum of fine cloth, the permeability of itself and resin is also best.Can find out that from the powerful detected value contrast table-7 of the tension of finished fabric yarn twist reduces the mechanical property that does not influence its finished fabric simultaneously.Can find out that from table-8 the reduction yarn twist can not influence the fabric appearance performance of glass cloth.
In sum, the ultralow twist yarn that comes into operation is produced glass cloth, and its woven air pressure has reduced 8%-12%, and the air penetrability of finished fabric has reduced 20%-30%, and the twist that reduces raw yarn not only can not influence the mechanical property of cloth cover, and the tension that has increased glass cloth on the contrary is powerful.The ultralow twist yarn that comes into operation has been saved the energy to the woven air pressure of loom on the one hand, and this has practiced thrift cost for company, and ultralow on the other hand twist yarn more helps out fine operation, and is ventilative more even, makes cloth cover more smooth, and this helps the resin penetration property of lower procedure.Ultralow sth. made by twisting glass cloth has good processing characteristics, and the added value of product that this has just improved my department has greatly increased me simultaneously and taken charge of the competitiveness of product in market.Ultralow twist yarn is produced the main trend that glass cloth is the glass fiber industry development so come into operation.
More than be that the production method of a kind of ultralow sth. made by twisting electronic-grade glass fiber cloth provided by the present invention has been carried out detailed introduction; Used concrete example among this paper structural principle of the present invention and embodiment are set forth, above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as limitation of the present invention.
