Description
Technical field:
The invention belongs to textile processing field, particularly cotton fabric processing method.
Background technology:
Along with social development, people get more and more to the demand of plyability function protecting clothes.Multifunctional composite finishing refers to the finishing technique giving two or more functions of fabric, as fire-retardant/antistatic, water and oil repellant/fire-retardant, antistatic/water and oil repellant etc.Water and oil repellant flame-proof treatment turn increases water and oil repellant performance on the basis of flame-proof treatment, and the taking of product is improved greatly.
Fire-retardantly refer to that textiles can automatically block burning and proceeds when meeting with burning things which may cause a fire disaster, automatic distinguishing after fire, not in afterflame or the ability of glowing.The flame-proof treatment of fabric is by effects such as chemical bonding, chemical adhesion, absorption deposition and nonpolar Van der Waals force combinations, makes fire retardant anchor on fiber and fabric, thus makes fabric obtain fire resistance.Cotton is a kind of natural plant fibre, and when heat reaches 300-400 DEG C, namely automatically cracking in atmosphere, produces imflammable gas, then with the combination with oxygen in air, impel burning to proceed.
Organo-fluorine polymer can be reduced to fabric face the degree that oil, water and spot can not infiltrate and penetrate fiber.The best finishing effect of this effect, be embodied in organo-fluorine polymer and can form seamed invisible diaphragm, this tunic gets up fibers encapsulation.Under drying process heat effect, organo-fluorine polymer is cross-linked film forming, sprawls come at fiber surface, and fluorine-containing side chain orientation is stretched, and polymer passes through effect and the fiber strong bonded of reactive group simultaneously.
Water repellent finish: refusing water and waterproof is two different concepts, and refusing water is be deposited on fiber surface with hydrophobic compound, and fabric face leaves hole, air and steam can also be through.Waterproof is that waterproof is airtight with the hole of fluid-tight compound filling fabric face.Its Main Differences is that refuse water has higher water permeability and porous gas under the effect of hydraulic pressure.
Oil-repellent finiss: be that after making loomage surface modification, critical surface tension significantly declines, the oil that effects on surface tension force is less also produces larger contact angle, thus oily effect is refused in generation.The fabric finishing agent that current energy is minimum is fluorocarbons finishing agent.
Summary of the invention:
The object of the invention is to overcome above-mentioned not enough problem, provide a kind of waterproof and oilproof flame-proof finishing process of COTTON FABRIC, technique is simple, and obtained COTTON FABRIC has waterproof, grease proofing and anti-flaming function concurrently.
The technical scheme that the present invention is adopted for achieving the above object is: the waterproof and oilproof flame-proof finishing process of COTTON FABRIC, arrange by the preshrinking process flow process of 1. enzyme desizing → drift → 4. mercerising of 2. singing → 3. boil → 5. dyeing → 6. flame-proof treatment → 7. water and oil repellent finish → 8., be specially:
(1) pre-treatment: comprise enzyme desizing → drift → mercerising four step of singing → boil, process conditions, enzyme desizing refinery practice, boil technique and the amount of caustic soda of drift, lower machine cloth capillary effect controls at 6 ~ 8cm/30min, pH value on-line monitoring during mercerising, ensures that lower machine cloth is neutral;
(2) pad dyeing: first the fabric after pre-treatment enters in groove and pad dye liquor, pick-up rate is about 65%, carries out infrared preliminary drying afterwards, hot blast preliminary drying (temperature 100 ~ 110 DEG C), and drying cylinder is dried; Pad fixation liquid again, gas steams (100 ~ 102 DEG C of * 1.5min), carries out 4 lattice washings successively, soap (soaping agent 1 ~ 2g/L, more than 95 DEG C) after decatize, and 3 lattice 95 DEG C washing and 1 lattice cold wash, dry after washing;
(3) flame-proof treatment: the fabric after dyeing enters in fire-retardant working solution and pads working solution, pick-up rate is about 65%, carries out infrared preliminary drying afterwards, hot blast preliminary drying (temperature 100 ~ 110 DEG C), drying cylinder is dried, then baking temperature (160 ~ 165 DEG C × 2.5min); Bake rear employing soda ash 30g/L neutralization, alkali cleaning, adopt three lattice, 50 ~ 60 DEG C of Warm Wash after alkali cleaning successively, four lattice 80 ~ 90 DEG C hot water wash, lattice 50 ~ 60 DEG C washing; Finally adopt the process of concentration 1 ~ 2g/L hydrogen peroxide, washing post-drying.
(4) water and oil repellent finish: after flame-proof treatment, fabric one soaks and rolls, and pick-up rate is that about 50%, 100 ~ 120 DEG C of * 3min are dried, then 180 DEG C of * 40s bake.

Wherein bleeding agent adopts the compatible high-efficient penetrant preferably with waterproofing agent.
Finishing technique of the present invention, not only technique is simple, is easy to industrial processes and produces, fabric not only water and oil repellant after arranging, and the micropore of cloth cover still exists, so do not change the gas permeability of fabric after arranging.
General phosphorus-containing compound produces phosphoric acid, metaphosphoric acid, poly-metaphosphoric acid in flame, and because the phosphoric acid layer generated forms the nonvolatile protective layer of one deck, isolated air, creates flame retardant effect.In addition, poly-metaphosphoric acid has strong dehydration, makes cellulose carbonization, and carbonizes the effect that film also serves isolated air.
Pad during flame-proof treatment: padding machine mangle is wanted evenly and band liquid measure should be consistent, because the change color of fabric after flame-proof treatment is comparatively large, in order to avoid produce aberration after arranging.
Dry: slowly should dry after textile pad dressing liquid and prevent finishing agent migration, make feel hardening.Bake out temperature is generally at 100 ~ 120 DEG C, unsuitable too high.If the too fast meeting of drying rate make fire retardant generation migration and move to that fabric face makes the feel of fabric become hard and coarse.Surface flame-retardant agent simultaneously increases, and is increased, cause washability to reduce by the trend washed off.Should make the regain that fabric keeps certain in addition during preliminary drying, when being beneficial to bake, fire retardant and fiber is full cross-linked.
Bake: baking is the major influence factors of finishing effect, dressing liquid is attached on fabric and produces flame retardant effect through baking with fiber generation cross-linking reaction through padding oven dry.
1.. baking temperature: the fire retardant on fabric just can react under certain temperature conditions, along with the increase cross-linking reaction of temperature is more abundant, flame retardant effect is better, but acidic materials in fire retardant bake through high temperature, and that fiber is occurred is tendering, powerful decline, temperature more high-tenacity declines more.
2.. bake the time: the fire retardant on fabric and fiber react and need the time, along with the increase crosslinking degree in reaction time is also more abundant, flame retardant effect is better, but powerful decline is also more.Can reach flame retardant effect for a long time with low temperature between high temperature, short time, but consider the brute force of fabric, general temperature selects 160 ~ 165 DEG C, and the time is 2.5min.Bake in process and will ensure the constant of temperature and the speed of a motor vehicle, be also noted that and suitably get rid of moisture in drying room and waste gas, to ensure to bake effect.
In and alkali cleaning: in and the object of alkali cleaning be that the acidic materials in fabric are neutralized completely, and the accessory substance produced in unreacted material and reaction is removed clean.Fabric first alkali immerging neutralization after through Warm Wash, hot water wash, dioxygen washing, dry.The object of dioxygen washing removes the peculiar smell on fabric.Flame-retardant textile after baking should be washed as early as possible because fabric has remaining acid, and fabric placement for a long time can be hydrolyzed and the brute force of fabric is declined in acid condition, and the fabric after general flame-proof treatment will clean complete in 4 hours.Fabric in flame treatment and after washing insufficient, easily produce fishlike smell when cloth cover pH value is greater than 8.5 and content of formaldehyde is high.The accessory substance mainly reacted is not removed clean, can use 2g/L hydrogen peroxide and 1g/L acetic acid wash.
COTTON FABRIC of the present invention adopts two-bath process finishing technique, i.e. first flame-proof treatment, then the index request carrying out that water and oil repellent finish can reach client.
