Abstract
The present invention relates to a method for arranging permeability acid, alkali, oil and water preventing fabric, which uses the method that the fabric is firstly coated and then arranged to enhance the acid preventing and the permeability performance of the fabric. High molecular materials which are used in the coating layer of the fabric mainly comprise polyacrylic acid aqueous or solvent type resin or polyurethane aqueous or solvent type resin. High molecular materials comprising fluorine are used to carry out acid preventing arrangement. The coated fabric is modified by using hydrophilic high molecular materials. Hydrophilic resin is polyvinyl alcohol resin. The present invention uses the method increasing the thickness of fluorine protective films on the surfaces of the fabric and fiber and increasing the quantity of the resin in the moisture (steam) infiltrating coating layer to thoroughly prevent acid and alkali liquid from directly contacting the fiber and infiltrating into the interior of the fibrous materials. Thereby, the present invention completely achieves the technical purpose of the processing arrangement of acid, alkali, oil and water preventing of all-cotton fabric.
Description
Technical field
The present invention relates to a kind of permeable acid-alkali-oil-water-proof fabric, especially have polyester-cotton blend and the all-cotton fabric and saturating vapour (wetting) the property acid-alkali-oil-water-proof method for sorting of well saturating vapour (wetting) property and multiple safeguard function.
Background technology
The situation of safety of China production in recent years is still severe, and in numerous accidents, deep-etchings such as acid, alkali, strong oxidation liquid also are one of principal elements to the injury of human body.In production, storing and the use of industries such as chemical industry, chemical fertilizer, nonferrous metallurgy, plating, battery, laboratory, military project and missile unit, splash, the race that acid, alkali, fuel and oil product often take place emitted, the water clock accident, cause personnel's positions such as body, leg injured, also can cause death when serious.Research and develop vapour and (comprise vapour and saturating wet, property acid-alkali-oil-water-proof fabric and clothes down together), can prevent chemicals such as acid, alkali, special fuel, oil product take place to run emit, water clock, the Shi Buhui that splashes injure human body, also can not produce sultry and uncomfortable sensation when wearing simultaneously this clothes for a long time.
The research of saturating vapour (wetting) property acid-alkali-oil-water-proof fabric and clothes does not have report at present as yet.But the gas permeability acid-proof Work Clothes of simple function has just begun research, production and equipment from early seventies abroad.1973, former Czechoslovakia just formulated acid-proof Work Clothes standard (CN832731), and standard has been made regulation to corrosion resistance, gas permeability and the seam fastness etc. of acid-proof Work Clothes; 1978 former Soviet Union acid-proof Work Clothes standard (г o с т 12.4.036.78) clothes material and style are stipulated; After this, Germany (DIN32763-830II type) industrially developed country of etc.ing all successively formulated and had labour health protective clothing or the anti-dangerous liquid chemical protection that acid-resistance requires and obey 1979 Japan (JIT8115-79), Britain (BS4171-1981) in 1980, France (SNFS74-02-80), nineteen eighty-three.Its International Standards Organization has also proposed regulation (ISO/DIS6529, ISO/DIS6530) to anticorrosive property Work Clothes and performance test methods after the eighties.China in 1989 has formulated acid-proof Work Clothes and method for testing performance standard thereof (GB12012～12013-89), though the branch of vapor-permeable type acid-proof Work Clothes and airtight type acid-proof Work Clothes is arranged in the standard, the clothes material of vapor-permeable type Work Clothes is not had physiological hygiene index requests such as clear and definite saturating vapour (wetting) property, toxicity.
The acid-proof Work Clothes of China eighties is continued to use rubber (airtight type) always, press materials such as silk and setation, some place is brought into use press for extracting juice silk/polyester filament intertexture, pure dacron and processed through simple acid-proof after the nineties other fabric and clothes, these materials are relatively poor to the impermeable ability of hydrochloric acid and nitric acid on the one hand, and its saturating vapour, comfortableness are not attached the importance yet on the other hand.Steam-proof (wetting) acid-proof lining is continued to use acid-resisting rubber cloth and Polypropylence Sheet always, and saturating vapour (property) acid-proof lining presses silk with natural protein fiber previously, and setation is a main material.The chemical stability of natural protein fibre is better, meets the no significant change of acid at normal temperatures, and acid is had stronger tolerance; Some Polymer Synthesizing fibrous material such as terylene etc. also have chemical-resistant stability preferably, meet acid and can not be corroded, and acid is had stronger tolerance.Though these materials all have good acid resistance, its fabric strength loss under the acid effect is less, is limited to the static pressure of acid solution and permeability defence, thereby also must puts in order with antacid and other resin.Fluorine material and the corresponding crosslinked resin thereof fabulous with chemical stability carry out special source mill to fabric; make it form firm protective at fiber and fabric face; when fabric runs into soda acid and strong oxidation liquid; fiber can not soaked into, be absorbed and be corroded; so Zheng Li fabric has the very good acidity of refusing in this way; antiacid pressure performance, acid resistance and certain acid-proof permeance property.Because fabric face does not form continuous diaphragm, it is very difficult that its acid-proof permeability will reach 30 minutes of standard-required, therefore must seek compound measure correspondingly, thoroughly solves the acid-proof permeability problems.
The fabric of process acid-proof arrangement is after it simultaneously imposes a certain amount of coating, and the anti-soda acid penetrating power of fabric improves greatly, but the also reduction greatly thereupon of saturating vapour (wetting) property is sultry, uncomfortable when fabric and clothes are worn.This is because most coating resins (EVA, PVC, rubber etc.) are the macromolecular materials of steam-proof (wetting), and after fabric imposed coating, saturating vapour (wetting) pipeline on its surface all was closed and loses vapour (wetting) function.Can reach vapour (wetting) property and anti-soda acid with the hydrophilic macromolecule resin to the coating material modification and ooze the dual purpose that ability improves.
Strictly speaking, both anti-sulfuric acid, nitric acid, hydrochloric acid, NaOH and potassium hydroxide liquid, the weaving face fabric that saturating again vapour is comfortable is extremely rare, is instant task so revise vapor-permeable type acid-proof Work Clothes standard as early as possible and carry out research and the production that the anti-soda acid of vapour (wet) property obeys lining.
Basic mechanical design feature indexs such as saturating vapour (wetting) property, the anti-alkalescence of acid-proof, grease-proof and waterproof performance, brute force, feel, toxicity, not only meet the project technical requirement, also meet the regulation of GB12012～12013-89 " acid-proof Work Clothes ", GB12799-91 " oil-resistant and waterproof protective clothing safety and sanitation performance requirement " and Q/320623KGF-07-2004 " saturating vapour (wetting) property acid-alkali-oil-water-proof fabric " simultaneously.Yield rate is more than 95%.
The main performance of saturating vapour (wetting) property acid-alkali-oil-water-proof fabric should reach following index request:
(1) vapor transfer rate: 〉=3000g/m

Summary of the invention
The present invention seeks to: coating material is carried out modification with the hydrophilic macromolecule resin, make coating material itself have higher saturating vapour (wetting) property, compound with the technology of uniqueness and parameter and acid-proof processing then, can make acid-alkali-oil-water-proof and the saturating all satisfactory fabric of vapour (wetting) property.Mainly be at polyester-cotton blend and all-cotton fabric, the special measure of saturating vapour (wetting) the property acid-alkali-oil-water-proof of all-cotton fabric arrangement especially.Because all-cotton fabric is not only very responsive to strong acid, aqueous alkali and strong oxidizer, but also has very high hygroscopicity, thereby be difficult to obtain meeting the product of specification requirement with the processing method of pure dacron or polyester-cotton fabric, the inventive method purpose especially: multi-functional all-cotton fabric is provided.
Saturating vapour (wetting) property acid-alkali-oil-water-proof fabric finishing method adopts the method for putting in order after the first coating can improve the acid-proof permeance property of fabric greatly.The macromolecular material that can be used for fabric coating mainly contains polyacrylic acid resinoid (PA glue-water-based or solvent-borne type), polyurethanes resin (PU glue-water-based or solvent-borne type).
Because its surperficial continuous film that forms of fabric with the arrangement of fluoro containing polymers emulsion is very thin, sometimes even can not form continuous film (thin fabric), so the acid-proof penetrating power to strong acid liquid is relatively poor, only the fabric hydrochloric acid time of penetration of fluorine arrangement clock more than 9 minutes does not only reach request of national standard.Have only the acid-proof permeability of coating+fluorine finish fabric just up to specification.
So that highly corrosion resistant high stability material---the fluoro containing polymers emulsion is carried out special arrangement to fabric; make fabric and fiber surface form firm fluorine diaphragm; the interfacial tension of fabric face reduces greatly: surface tension when not putting in order (cotton, polyester-cotton blend, pure terylene) is 65～28 dyne/cm; after the arrangement 5～22 dyne/cm; and the surface tension of water droplet (comprising that acid, alkali lye drip) is 75 dyne/cm; oil droplets 30 dyne/cm, thus reach the soda acid aqueous solution and the nonwettable purpose of oils liquid.In fact the refusing sour efficiency index and can reach more than 98% of this fabric, anti-oil reaches 130 fens, refuses 5 grades in water.
With hydrophilic high molecular material coated fabric is carried out modification, both can improve the antiacid alkali ability of coated film,, give coated film certain saturating wet function simultaneously again by hydrophilic radical " transmission " hydrone.

The specific embodiment
Table 1 coating is to the influence of fabric acid-proof penetrating power
Annotate: fabric is 42
S/ 2 * 16
SThe polyester-cotton blend khaki
Can see in sum: moisture-penetrating coating and fluorochemical unite the arrangement be the desirable compound compatible technique of saturating vapour (wetting) property acid-alkali-oil-water-proof.
Generally do not adopt kinds such as Corvic (PVC), polyvinyl acetate esters resin (EVA) and rubber (natural and synthetic).Because rubber mostly sealing is fabulous, saturating vapour (wetting) poor performance, though and PVC and EVA low price, harder feel can influence the wearability of fabric, washability is poor.
The main performance feature of table 2PA and PU coated fabric
Annotate: (1), fabric are 42S/2 * 21S polyester-cotton blend khaki;
(2), fluorine-containing antacid use amount is identical;
(3), the time of penetration of nitric acid and hydrochloric acid is answered 〉=30min (GB12012 regulation).
As can be seen from Table 2: PU resinous coat any surface finish, smooth, flexible, fabric feeling is than softness and attachment fastness height; The PA-1 resin is compared with the PU resin and is had following characteristics: the few (16.35g/m only of spread
2), anti-hydrochloric acid penetrating power outstanding (PA is 41.13min, and PU is 24.45min), price are cheap, and (PA is 1.17 yuan/meter
2, PU is respectively 4.76 and 1.43 yuan/meter
2), its coating surface, fabric feeling and attachment fastness are close with the PU resin, and the present invention selects PA-1, PU resin for use.
In order to strengthen vapour (wetting) property, can hydrophilic high molecular material (DS-305) to the PA resin modified, improved saturating vapour (wetting) performance of fabric coating.The coating material consumption is listed in table 3, Fig. 2 and Fig. 3 to the influence of fabric acid-resistance, feel and washability.
The main performance of table 3, coating material and anti-soda acid fabric
Annotate: (1), test fabric are polyester-cotton blend khaki: 42S/2 * 21S;
(2), the coating material consumption in fabric coating after the percentage that increases of weight;
(3), the antacid concentration of Shi Yonging is identical.
Can see from table 3 and Fig. 1: along with the increase of coating material consumption, acid time of penetration lengthening, and influence degree nitric acid is greater than hydrochloric acid: nitric acid reaches at 10.17% o'clock in the coating amount, and time of penetration could alignment request up to standard 30 minutes, and hydrochloric acid o'clock can meet the demands at coating materials 6～7%; Along with the increase fabric feeling hardening of coating material consumption, cost raises.Can see also that from table 3 along with the increase of coating material consumption, the acid-proof washability strengthens, the time of penetration lengthening of washing back hydrochloric acid and nitric acid.Fig. 2 has shown the increase along with the coating material consumption, the eluting rate of fabric reduces, further proved the influence of coating material, so when selecting the coating material consumption, must weigh the reasonable disposition between acid-resistance, washability, fabric feeling and the production cost to washability.
The DS-305 hydrophilic resin is a polyvinyl alcohol resin, and the consumption 24～42% of DS-305 is comparatively suitable.Because the difference of fabric fiber material, during identical DS-305 consumption, the vapor transfer rate of fabric also has than big-difference, as the vapor transfer rate of saturating vapour (wetting) property acid-alkali-oil-water-proof cotton khaki drills is: 4170g/m
2And the polyester-cotton blend khaki vapor transfer rate of same amount is 3230g/m .24h,
2But the vapor transfer rate of two kinds of fabrics all meets standard-required .24h.
The anti-soda acid of fluorine-containing antacid, crosslinked resin and fabric, grease-proof and waterproof performance:
Fluoro-containing macromolecule material has high chemical stability, corrosion to chemicals such as acid, alkali, strong oxidizers has good ability to bear, as with perfluorinate acrylic polymer emulsion (DS-106, DS-107) as antacid and be equipped with other material and cotton, polyester-cotton blend, pure dacron are carried out acid-alkali-oil-water-proof arrangement obtained satisfied result.When Fig. 3 had provided fluorine-containing antacid-DS-106 all-cotton fabric is put in order, sour time of penetration was along with the variation of antacid working concentration; Table 4 has provided the grease-proof and waterproof performance of fluorine-containing antacid and fabric.
Can be seen by Fig. 3: the acid-proof time of penetration of (1), fabric prolongs along with the increase of antacid concentration, (2), the prolongation amplitude of hydrochloric acid will be lower than nitric acid, (3), the time of penetration (〉=30 minutes) that will be up to state standards and stipulate, nitric acid only needs the antacid concentration about 25%, hydrochloric acid then needs the concentration more than 30%, this has proved that hydrochloric acid is positioned at first of three big inorganic acids the damage capability of fabric, and we have also awarded special concern in the research.
As can be seen from Table 4, fluorine-containing antacid has fabulous grease-proof and waterproof performance, and under the situation of working concentration lower (19%), the grease proofing and water resistance of fabric can reach the value (130 minutes and 5 grades) of standard code; And the acid-proof performance improves along with the increase of anti-acid concentration, and when having only antacid concentration to reach certain value, the acid-proof performance of fabric just can meet the requirements.
The grease-proof and waterproof performance of table 4 antacid and fabric
Annotate: the test fabric is a cotton half line card; It is identical to be coated with the room material usage.
With the common crosslinked resin that uses of fluorine-containing antacid be a kind of macromolecular material that contains active group, it with fibrous material and the big molecule of antacid in the active group reaction, form firm chemical bond combination, can improve the washability that fabric is prevented soda acid greatly; Simultaneously the active group of cross linking agent also can be separately with fluorine-containing antacid on active group reaction formation network structure; improved the fastness and the thickness of fluorine diaphragm on the fabric greatly; thereby also improved the acid-proof penetrating power of fabric, table 5 and Fig. 4 have provided the influence of crosslinked resin to fabric acid-resistance and washability.The principal item of crosslinked resin is: modified cyanurotriamide resin.
As can be seen from Table 5: along with the increase of crosslinked resin consumption, the time of penetration of nitric acid and hydrochloric acid increases, and the acid-proof performance improves; But along with the increase of dosage of crosslinking agent, the fabric weightening finish increases, and production cost strengthens, and the fabric feeling hardening.Fig. 4 has provided the increase along with the crosslinked resin working concentration, sour time of penetration lengthening after the fabric washing, and washability improves, and also can draw identical conclusion from the variation of the eluting rate of fabric.The consumption of crosslinked resin directly has influence on acid-resistance, washability, fabric feeling and the production cost of fabric, should be the optimum organization of multiple index in the use, and scope is advisable 3～8%.
Table 5 crosslinked resin is to the influence of fabric acid-resistance and feel
Annotate: (1) test fabric is polyester-cotton blend khaki: 42S/2 * 21S;
(2) no moisture-penetrating coating is compound; The antacid working concentration is identical.
The composite science of moisture-penetrating coating and fluorine-containing antacid
The arrangement of fluorine-containing antacid can only improve refuse soda acid performance, acid-proof alkaline and the antiacid alkali of fabric and press performance, and relatively poor to the anti-permeability of strong acid (as nitric acid, hydrochloric acid etc.); Though soda acid is refused in raising to moisture-penetrating coating and acid-proof alkaline is limited, can improve impermeable ability and the antiacid alkali pressure of fabric greatly, the reasonable composite selection that is only science of two kinds of technical measures to strong acid-base liquid.Fig. 5 has provided the variation of polyester-cotton fabric acid time of penetration with fluorine-containing antacid of DS and PA moisture-penetrating coating usage ratio.As seen from Figure 5: along with the increase of DS/PA ratio, the sour time of penetration of fabric all is tending towards constant (41.7 minutes), be not less than 30 minutes requirement according to time of penetration before GB and the company standard washing, up to standard during hydrochloric acid 14%, up to standard during nitric acid 17%, uniformity according to performance and benefit is considered, the ratio 17%～21% of DS/PA is more rational.The ratio of DS/PA is meant the weight ratio of antacid and coating.Fibrous material is to the influence of finishing technique
The influence that the chemical analysis of fibrous material, the difference of molecular structure are put in order acid-alkali-oil-water-proof is bigger.When table 6 has provided same recipe and finishing technique, the characteristic of different fiber material fabrics.
As can be seen from Table 6: under the close situation of fabric weightening finish, grease proofing, the waterproof of three kinds of fabrics with refuse acid identical, and all reached the requirement of national standard and company standard, but the time of penetration difference of nitric acid and hydrochloric acid is bigger: the sour time of penetration of polyester-cotton blend and pure dacron is all grown (41.7 minutes), considerably beyond GB and enterprise's target requirement, and all-cotton fabric is nitric acid (26.75 minutes) or all substandard requirement of hydrochloric acid (24.98 minutes).This is because cotton fiber is by cellulose macromolecule, multidimensional three-dimensional-structure, and contains very active hydroxyl in the big molecule, thereby very sensitive to acid-alkali medium, due to the while hygroscopicity is also higher.
Table 6 fibrous material is to fabric acid-proof Effect on Performance
Annotate: (1) three kind of fabric is 42S/2 * 21S khaki, and the blending ratio of polyester-cotton fabric is 65/35;
(2) Zheng Li prescription and technology are identical.
Performance characteristics according to all-cotton fabric; the consumption that the present invention has taked to improve the thickness of fabric and fiber surface fluorine diaphragm and increased saturating wet (vapour) coating resin; thoroughly stop soda acid liquid directly to contact fiber and be penetrated into fibrous material inside, thus satisfactory solution the technical barrier of all-cotton fabric acid-alkali-oil-water-proof processing and sorting.

Acid-proof fabric commonly used mainly contains the press for extracting juice silk that produces in Liaoning or presses silk and polyester filament intertexture on the domestic market at present, and the characteristics of this acid-proof cloth are that certain saturating vapour (wetting) performance is arranged, but very poor to the barrier propterty of hydrochloric acid; Steam-proof (wetting) the type coating acid-proof cloth that produce in Henan is though still can to the barrier propterty of sulfuric acid.
The domestic and international four kinds of multifunctional fabric performances of table 10 relatively
Acid and nitric acid have barrier propterty preferably, but also undesirable to the protection of hydrochloric acid.The anti-soda acid fabric that ground in 2000 in Shanghai also is at than the sulfuric acid that is easier to protect, and the nitric acid and the hydrochloric acid of difficulty or ease protection is not related to, and the saturating vapour (wet) of this fabric is measured very little (1980g/m
2.24h), do not reach ventilative comfortable basic demand (〉=2300g/m
2.24h).
Table 10 has been listed the comparison of several close product main performances.
Can see from table 10 data: (1) existing good saturating vapour (wetting) performance, it is characteristics of the present invention that the anti-four kinds of safeguard functions of alkali-oil-water-proof of acid-proof are arranged again, other three kinds of products are not only on saturating vapour (wetting) property, and are and all bigger with this research difference on function quantity and product material.Vapour of the present invention (wetting) property acid-alkali-oil-water-proof fabric not only has well saturating vapour (wetting) property and four kinds of safeguard functions, and is the most outstanding on the performance, and reached industrial production and practical requirement.The industrial vapour of mass (wetting) property acid-alkali-oil-water-proof fabric is sold to departments such as chemical industry, chemical fertilizer, coloured smelting respectively and is done industrial and protective clothing, on probation through dress, consistently think vapour (wetting) property acid-alkali-oil-water-proof Work Clothes, not only has multiple safeguard function, and protective capacities is strong, wear pleasant, the washing repeatedly the back performance variation little, the intensity height is fit to the work operation.By of the developmental research of simple function material, thereby enlarged the frontier that the security protection material is used to multifunctional material.Saturating vapour (wetting) property, acid-proof, the alkali prevention of textiles, the compound compatible technique mechanism of grease-proof and waterproof have been analyzed; The basic theoretical knowledge of application of advanced is carried out special processing with materials such as moisture-penetrating coating and fluoro containing polymers resins to pure dacron, polyester-cotton fabric, antistatic polyester-cotton fabric and all-cotton fabric and has all been reached five kinds of compound compatible results that function is splendid; Solved the all-cotton fabric that all is difficult to for a long time break through both at home and abroad and prevented the soda acid process technology, for the acid-proof base material has increased a more comfortable kind.The production procedure of saturating vapour (wetting) property acid-alkali-oil-water-proof fabric is reasonably, and prescription and technological parameter are feasible.It is the most commonly used that the present invention is used for cotton, polyester-cotton blend or pure dacron, also is used for the BLENDED FABRIC of hair and terylene.
