Description
Technical field
The invention belongs to textile technology field, the preparation of a kind of polypropylene fiber fabric and the pre-place of liquid many conjunctions printing and dyeing
Science and engineering skill.
Background technology
Polypropylene fiber is also known as polypropylene fibre.Abundant raw material source, production technology is simple, and product price compares, and other close
Become fiber cheap；The physical and mechanical properties feature of fiber is: intensity high (chopped fiber is 4～6 g denier, long filament is 5～8 grams/
Denier), wet strength and dry strength are essentially identical, proportion little (0.91), wear-resistant corrosion-resistant etc.；Owing to polypropylene has production technology letter
The advantages such as single, product is inexpensive, and intensity is high, and relative density is light, so polypropylene develops quickly.Current polypropylene has been synthetic fibers
The fourth-largest kind, is fiber the lightest in general chemical fiber.
The maximum advantage of polypropylene fiber is that quality is light, its density only 0.91g/cm3 be general chemical fiber Midst density
Light kind, so the higher area coverage that the polypropylene of same weight obtains than other fibers；Intensity is high, and elongation is big, just
Beginning modulus is higher, excellent spring.So polypropylene wearability is good.Additionally, wet strong being substantially equal to of polypropylene is done by force, so it is to make
Fishing net, the ideal material of hawser.
Polypropylene fiber light weight warmth retention property is good, moisture absorption hardly, but wicking capacity is very strong, and moisture absorbing and sweat releasing effect is obvious；Polypropylene
Hygroscopicity the least, moisture absorption hardly, the regain under the conditions of general atmosphere is close to zero；But it has core sucting action, can pass through
Capillary tube transmission steam in fabric, but itself does not play any Absorption, and the dyeability of polypropylene is poor, and chromatograph is the most complete；Existing
Have in technology, on market substitute alkali be dye for reactive dyestuffs in exhaustion in the high cost of soda, use inconvenience and developing to open
A kind of new product sent out, with calcium hydroxide as dispensing, while being effectively reduced dyeing alkaline agent cost, and can improve dyeing
One-time success rate, hence it is evident that reduce dyeing integrated cost.
But, although substitute alkali has above-mentioned advantage on the market, but in use there is also some problems, substitute alkali pair
The colour fixation of polypropylene fiber structure-activity dyestuff has obvious selectivity；Reactive dye are made alkaline agent with substitute alkali and are contaminated, and are permitted
Low 5%-10% when the high colour-fast rate of many dyestuffs makees alkaline agent than natrium carbonicum calcinatum, some dyestuff dye-uptake is understable, dyeing color
The dyeing deviation of light and soda, still there is main problem for substitute alkali containing a large amount of color patterns difference etc., substitute alkali fixation rate with
With the deviation of soda form and aspect, the coffee of bright the reddest colorant match, purple even depth are not as soda, and form and aspect are excessive with soda difference,
Effect is undesirable；Meanwhile, the in use easy calcium deposit that formed in dye vat of the calcium hydroxide in substitute alkali is difficult to remove, greatly
Have impact on greatly follow-up printing quality.
Summary of the invention
The technical problem to be solved is, the shortcoming overcoming prior art, it is provided that a kind of polypropylene fiber fabric
Preparation and liquid many conjunctions printing and dyeing pretreating process, it is possible to make fabric have high resiliency, high intensity, fast light advantage warming, heat-resisting,
Meanwhile, it is capable to rapid osmotic diffuses to fiber on fabric in follow-up dye liquor, effectively prevent that cylinder in dyeing process is poor, color
Flower, aberration and the generation of fixation speckle.
In order to solve above technical problem, the present invention provides the preparation of a kind of polypropylene fiber fabric and close of liquid to print and dye in advance more
Process technique, selection through weft material be according to the mass fraction: polypropylene fiber 40-90 part, combed cotton 20-40 part, super fine denier
Terylene 8-18 part, the preparation section of described fabric lining is scutching cotton, comb and parallel cotton fibers prior to spinning, drafting, rove, spun yarn and weaving operation, wherein: institute
State operation of weaving cotton cloth and include warping, Vacuum shaping, sizing and jet operation；
In described sizing operation, adding liquid many conjunctions auxiliary agent in slurry, described liquid many conjunctions auxiliary agent is sodium hydroxide, chelating
Agent and the aqueous solution of sodium hexameta phosphate, this liquid pH value closing dyeing used additives is 2g/L:8.5 ± 1 more, wherein；
Described sodium hydroxide, chelating agen and sodium hexameta phosphate are respectively as follows: according to the mass fraction
Sodium hydroxide: 0.5-1.5 part, chelating agen: 0.2-0.5 part, sodium hexameta phosphate: 0.2-1 part, described sodium hydroxide,
The gross mass of chelating agen and sodium hexameta phosphate and the mass ratio of water are 2:50；And after slashing technique terminates according to fabric wait contaminate
Material concentration insulation 50-80min；
Described Vacuum shaping concretely comprises the following steps:Being pushed by fabric in steaming silk case and water filling in case, water injection rate control is
Not having 1/3rd of fabric height, silk case is steamed in preheating makes its internal temperature reach 20-35 DEG C；Utilize water ring vacuum pump to case
Internal carry out for the first time evacuation, and box house is heated so that low-temperature saturated steam is penetrated in fabric, heating
0.6-0.8h keeps case body temperature to stand 45-50min after reaching 80-90 DEG C；Casing after standing is carried out second time take out
Vacuum, and again inside heating compartment, heat time heating time, 30-45min, kept case body temperature to be 86-95 DEG C；After heating terminates
It is incubated and stands 25-30min, i.e. completing the Vacuum shaping of fabric.
Technique effect: owing to the present invention uses above technical scheme, use polypropylene fiber, combed cotton and superfine denier polyester
Blending so that fabric has high resiliency, high intensity, fast light advantage warming, heat-resisting；It is to carry out fiber that Vacuum shaping processes
Humid heat treatment, appropriate humid heat treatment is to the effect of having greatly improved of the physical and mechanical properties of fiber, after fiber absorbs moisture, meeting
Releasing heat, now, fiber molecule warm-up movement weakens, and internal structure stability strengthens, and now gives yarn a certain degree of heat
Amount compensates, and keeps continuing and stable of this state, makes yarn ectonexine can be significantly improved the entirety of fabric by equal heat treatment
Performance；
Owing to, in the dyeing process of textile, dyestuff enters the process of fibrous inside and is divided into:Absorption,Diffusion and
Set, yet with the performance deficiency of soda, absorption and diffusion process interfere impact, it is impossible to reach high-level printing and dyeing effect
Really, and after in the present invention, sodium hydroxide, chelating agen and sodium hexameta phosphate fully dissolve, when carrying out printing and dyeing operation as auxiliary agent, energy
Enough in dye liquor and on cloth cover rapid osmotic diffuse to fiber, effectively prevent that cylinder in dyeing process is poor, color colored, aberration and fixation
The generation of speckle；
Printing and dyeing pretreatment designed by the present invention, due to liquid many conjunctions auxiliary agent quick diffusion performance, greatly reduces
Dye adsorption diffusion time, it is used alone soda it is generally required to the time of 5min completes, and employs that liquid closes dyeing and use more
Auxiliary agent pretreatment then have only to 2min i.e. can the effect of this excellence, shortening time of whole operation reaches 60%, thus significantly
The energy consumption in dyeing process and workload are saved；
The technical scheme that the present invention limits further is:
Further, the preparation of aforesaid polypropylene fiber fabric and liquid many conjunctions printing and dyeing pretreating process, described liquid is many
