Four, description of drawings
Fig. 1 is a process chart of the present invention
Five, the specific embodiment
The anti-static method of natural fabric of the present invention adds warp-wise or broadwise equally spaced inweave electrically conductive organic fibre or the metallic conduction fiber (or blending go into stainless steel fibre) of man-hour at fabric with electrically conductive organic fibre or metallic conduction fiber (perhaps stainless steel fibre) in weaving.Natural fabric of the present invention comprises cotton, hair, fiber crops or viscose, also comprises the blending synthetic fiber at the fabric that is not more than 10%, also comprises the BLENDED FABRIC of natural fabric certainly.
The characteristics of the anti-static fabric that the present invention adopts are: antistatic durability fine (but wash resistant is more than 100 times); The consumption that also can align conductive fiber satisfies the different requirements of different product to antistatic performance; The topped property of this coloration of textile materials (can dye colourless conductive filament) is better simultaneously, and cost is lower, adopts the method so labor protection is taken anti-static fabric more.The present invention selects for use colourless conduction nylon fiber to produce the natural fabric anti-static fabric.
The flame-proof treatment new method: with materials such as fire retardant and crosslinking agents natural fabric being put in order, is advanced flame treatment technology, is characterized in that technology is simple, Different Weight, and the fabric of different structure can suitably be adjusted prescription, explained hereafter.
Selection of fire retardant has multiple: east, Jiangsu rises DS-01, Zhangjiagang, Jiangsu JHPC, Beijing sky day H-01, Switzerland Pyrovatex CP
The method of Chang Yong natural fabric flame-proof treatment mainly contains two kinds of Proban method (Britain) and Pyrovetex cp methods (Switzerland gas Ba Jiaji company) in the world: the characteristics of Proban method are that fire-retardant washability is good, the fabric strength loss is little, but the feel of finish fabric is stiffening, color and luster changes greatly, but also needs special-purpose ammonia cure equipment, oxidation and soap abundant; Pyrovetex cp method is less to the fabric color influence, feel is soft, again can with the shared exploitation that helps new product of other functional aid, and need not special equipment, if prescription, craft science is reasonable, the strength loss of finish fabric and washability can both reach requirement, are to develop method for sorting the most rapidly at present.The flame-retardant finishing method that this research is selected for use is the resistive arrangement new technology of the SD between Proban and Pyrovetex cp.
The present invention adopts P-N type fire retardant (DS-101) to roll-to bake technology antistatic natural fabric such as cotton tribute silk to be handled, and according to orthogonal experiments, table 2 has provided the relation between fabric weightening finish and the anti-flammability.As can be seen from Table 2: along with the increase of fire retardant working concentration, the weightening finish rising of finish fabric, char length reduce, and production cost strengthens, and should use minimum fire retardant under the prerequisite that guarantees flame retardant effect and washability in the actual production.
The working concentration of fire retardant is when 32%-42%, and the fabric weightening finish is 14%-17%, and char length is 75mm-100mm, and such index can meet the regulation of domestic and international various fire-retardant textiless and clothes, is the concentration scope of application an of the best.
The relation of crosslinked resin and fabric weightening finish and washability
Crosslinking agent is a kind of compound with sp act group, under suitable condition it can with the active group chemically reactive (seeing reaction equation 1.2.) of fire retardant, cotton fiber, form firm chemical bond combination, on fabric, tie up fastness thereby improve fire retardant greatly, increasing the washability of finish fabric.
The present invention has taked two technical measures: the one, under the situation that does not influence fabric feeling and brute force, suitably strengthen the consumption of crosslinking agent, to improve the anti-flammability of finish fabric; The 2nd, use compound crosslinking agent, improving activity, adhesiveness and the permeability of crosslinking agent, table 3 is given in the influence to the finish fabric eluting rate of the kind of crosslinking agent under the constant situation of fire retardant consumption and consumption.
Crosslinking agent is except that DS-202,203 and mix to use, and also comprises the DS-304 resin, and production company is the fast enterprise such as fire proofing factory that reaches of gas Ba Jiaji company, the Zhejiang development of evil in febrile disease, Zhengzhou.
Under the constant situation of fire retardant consumption, along with the increase of dosage of crosslinking agent, the weightening finish rising of finish fabric, char length descend.When dosage of crosslinking agent 8-9%, fabric weightening finish 15-17%, char length 80-85mm, this is a proper consumption.
Then through the dirty arrangement of waterproof and oilproof: and waterproof and oilproof is dirty and fire-retardant method is in two steps carried out: promptly earlier fabric is done flame-proof treatment, remake the dirty processing of waterproof and oilproof then.
The selection of antistatic, fire-retardant, the dirty compound compatibility of waterproof and oilproof:
Antistatic, fire-retardant and waterproof and oilproof is dirty generally is conflicting, because antistatic commonly used, the dirty agent of waterproof and oilproof (as organosilicon, stearic acic derivative etc.) all are combustible material, when they and fire retardant are common, not only be equivalent to the minimizing of fire retardant consumption on the fabric, and the dirty agent of antistatic agent, waterproof and oilproof is attached to fiber surface more, causes the anti-flammability of fabric to descend and the afterflame increasing of fabric face.The invention solves this problem.
The anti-flammability synergistic theory of nonflammable and phosphorus, halogen element according to most of metals and oxide thereof, the electrically conductive organic fibre that will contain metal oxide (or lemel) earlier, form the antistatic grey cloth as the equally spaced fabric that inweaves of warp thread, again through pre-treatment and dyeing, divided for two steps fabric was put in order with the dirty agent of phosphonium flame retardant and fluorine-containing waterproof and oilproof at last, promptly obtain to have antistatic, the natural fabric of fire-retardant, dirty four kinds of functions of waterproof and oilproof.
Table 1 has provided the anti-oily water repellent of different cultivars to carrying out the finishing effect of antistatic and fire-retardant converted goods.
| Conductive fiber | Fire retardant | Water and oil repellent agent | Static electricity resistance μ c/ spare | Char length mm | Surface after flame time S | Anti-greasy dirt branch | The water proofing property level |
| Conduction nylon | DS-101 | Do not have | 0.42 | 70.8 | 0 | ＜50 | ＜1 |
| Conduction nylon | DS-101 | 203 silicone oil | 0.42 | 120.0 | 15 | ＜70 | 4 |
| Conduction nylon | DS-101 | The FTC stearic acic derivative | 0.42 | 125.0 | 10 | ＜70 | 4 |
| Conduction nylon | DS-101 | FC-50 (fluorochemical) | 0.42 | 72.7 | 1.5 | 130 | 5 |
Annotate: (1) fabric is 32S/2 * 32S/2 natural fabric tribute silk; 1/1.5 centimetres of conductive warp yarn spacings;
When (2) not fire-retardant and waterproof and oilproof dirt was handled, the antistatic performance of fabric was 0.4 μ c/ spare.
May see from table 1: the dirty agent of fire retardant and waterproof and oilproof is to the not influence of antistatic performance of fabric; When 203 silicone oil and FTC stearic acic derivative and DS-101 fire retardant were shared, the char length of fabric increased to 120mm by 70.8mm, and after flame time reaches 10-15 second, had surpassed 5 seconds national Specification; And with the dirty agent FC-50 of waterproof and oilproof when shared, the anti-flammability of fabric is constant substantially, and the dirty performance of waterproof and oilproof, feel, brute force, saturating index such as wet all meet the requirements; Therefore industrial production promptly adopts the compound compatible process technology of the dirty agent of electrically conductive organic fibre, phosphorus flame retardant and fluorine-containing waterproof and oilproof.
The factor that influences fabrics flame resistance mainly is the dirty agent of conductive fiber, fire retardant and waterproof and oilproof: what conductive fiber was selected for use is the composite nylon fiber that adds metal oxide, and certain anti-flammability is arranged itself, and the few (0.1-0.3g/m of use amount in the fabric
2), little to the anti-flammability influence of whole fabric; The dirty agent of waterproof and oilproof is a kind of perfluorinated alkyl fluoride hydrocarbon compound, contain very high fluorine element (halogen), it and phosphorus flame retardant have good synergistic, the natural fabric of discovery after flame-proof treatment handled with the dirty agent of waterproof and oilproof again in the experiment, the anti-flammability of fabric is without any variation, and both synergistics are fairly obvious; The consumption of fire retardant has become to influence the key factor of fabrics flame resistance.
Relation between weightening finish of table 2 fabric and the char length
Annotate: the canvas specification is 21S/3+3 * 21S/4; The tribute silk specification is 32S/2 * 32S/2.
Table 3 crosslinking agent kind and consumption are to the influence of fabric eluting rate
Annotate: used fabric is 32S/2 * 32S/2 antistatic natural fabric tribute silk.
Can be seen by table 3: under the constant situation of fire retardant consumption, when using crosslinking agent DS-202 (8-5%) separately, eluting rate minimum (47.9%), the fabric weightening finish is maximum, char length is the shortest, but fabric feeling is relatively poor; And when using crosslinking agent DS-203 separately (8.5%), eluting rate the highest (59.3%), the fabric weightening finish is minimum, char length is the longest, fabric feeling is the most soft.Consider from the overall target of finish fabric.Crosslinking agent DS-202 and DS-203 are shared more reasonable, and especially shared amount about 8.5% (about DS-2027.28, about DS-2031.22%) is the most suitable.With other crosslinking agent similar effect is arranged.
Bake with crosslinked
It is crosslinked that the present invention adopts high temperature to bake set, this is a very complex physicochemical process: the covalency interlinkage (seeing molecular formula 1) of natural fabrics such as existing fire retardant and cotton, have again fiber, fire retardant and crosslinked between valence link in conjunction with (seeing molecular formula 2), also have simultaneously fire retardant, crosslinking agent to the infiltration of fabric construction and cotton fiber inside, adhere to, form very firm physical absorption by intermolecular secondary bond power.
The present invention adopts baking temperature 150-170 ℃, and baking time 2-6 minute is comparatively reasonably to bake crosslinked condition.
The fastness of waterproof and oilproof dirt
The kind of water and oil repellent agent and use amount have determined the dirty performance (seeing Table 4) of the waterproof and oilproof of finish fabric to a great extent.Though water and oil repellent agent DS-105 also has certain adhesiveness to cotton fiber, when composite with it, fastness is difficult to reach practical requirement without crosslinked resin.It is shared with water and oil repellent agent DS-105 that this research use has highly active crosslinked resin (DS-202), and be equipped with appropriate catalyst, the pH value conditioning agent, when set is crosslinked, by means of water and oil repellent agent and crosslinking agent and the macromolecular chemical bond of cotton fiber, improved the wash resistant fastness of the dirty fabric of waterproof and oilproof greatly.Table 5 has provided the relation of crosslinked resin use amount and the anti-greasy dirt fastness of fabric waterproof.
Can the compound that contain the halogen family element only be arranged with the water and oil repellent agent of phosphorus flame retardant synergistic.The present invention select for use the aliphatic compound that contains fluorine element as can with the dirty agent of the waterproof and oilproof of fire retardant synergistic.Its kind mainly contains: Yixing, Jiangsu FC-105, Japanese rising sun Xiao Zi AG-480, Ciba oleophobol, Hangzhou development of evil in febrile disease TF-410H.
Four kinds of water and oil repellent agents all are fluorochemicals, but because of the difference in its chemical constitution, fluorinated volume, original producton location etc., its performance and price difference are bigger, and it is functional that present embodiment is especially selected for use, low-cost FC-50 water and oil repellent agent.
