Description
Technical field
The present invention relates to spun-laced nonwoven fabric regeneration production field, a kind of 100% regenerated fiber be raw material spun lacing without
Spin cloth.
Background technology
Spun-laced nonwoven fabric is by fine for high pressure water flow jet to one or more layers fleece, makes fiber mutually become entangled in one
Rising, so that fibre web is reinforced and possessed certain strength, prepared fabric is spun-laced nonwoven fabric.Its fibrous raw material source is wide
General, can be terylene, chinlon, polypropylene, viscose rayon, chitin fiber, superfine fibre, tencel, silkworm silk, bamboo fibre, wood pulp fibre
Dimension, alginate fibre etc..
Tradition hydro-entangled non-woven fabric (being commonly called as: spun-laced nonwoven fabric) is that to use the chopped fiber such as terylene, viscose glue or Cotton Gossypii be main
Wanting raw material, fibre length is all between 30mm-40mm, and the requirement to fibre length is higher.
Our company is explored by 10 years of researches, by technological innovation, process innovation, develops a kind of 100% regeneration fibre
Dimension is the production process of spun lace nonwoven fabric of raw material, produces in the rim charge produced and Apparel Manufacturing when i.e. utilizing nonwoven production
Leftover pieces, produced 100% regenerated fiber hydro-entangled non-woven fabrics, its low cost, performance is the most defeated in traditional viscose glue, terylene is
The conventional spun laced fabric of raw material, product safety is reliable, through strict detection, has been used to food service industry cleaning cloth for wiping or dusting.
But, in process of production, still there are certain technical barrier needs and overcome, such as, 1, fine to leftover pieces
During the regeneration pretreatment tieed up, how to reduce the friction between regenerated fiber and tangle, reduce fiber electrostatic；2, do not affect regeneration simultaneously
Fiber fibre cohesion in the rear road course of processing；3, reduce the short flannel of regenerated fiber, dust the most as far as possible, reduce shredding
The cotton knot produced in regenerative process；4, how to avoid or reduce produce during use hair, fall bits；5, due to regeneration fibre
It is big that dimension has fiber length difference, average length short (between 2mm-30mm), and fiber is straight, and curling is few, and short flannel, dust content are high,
When carrying out shredding, mixing, how to reduce the damage of regenerated fiber, improve the utilization rate of fiber；6, when carding, regeneration
Fiber becomes the coherency and strength after net poor；7, when carrying out spun lacing, if using conventional Spunlace line and technique, liquid drugs injection pressure
Power and negative pressure-pumping can cause chopped fiber, the loss of short flannel in regenerated fiber；8, tradition water circulation system filters effect to impurity
Fruit is not strong, causes meeting water quality to decline, affects spun lacing effect, and then affect the quality of product water prick nonwoven cloth.
Summary of the invention
For solving above-mentioned technical barrier, the invention discloses the production work of the spun-laced nonwoven fabric of a kind of 100% regenerated fiber
Skill and method.
For solving above technical problem, present invention provide the technical scheme that
The spun-laced nonwoven fabric of a kind of 100% regenerated fiber, it is characterised in that the spun-laced nonwoven fabric of described a kind of 100% regenerated fiber
Production method, comprise the steps of
(1), pretreatment of raw material: the leftover pieces of recycle-water prick nonwoven cloth or the leftover pieces of clothing factory, carry out go-on-go, will be contaminated
, impure many leftover pieces reject；
(2), raw material reprocessing: in step (1) on the raw material after sorting, with spray pattern, spray dedicated fiber inorganic agent, and
By spraying the leftover pieces of dedicated fiber inorganic agent, stack from bottom to top, then cover thin film close vexed 20 ~ 36 hours；
(3), shredding: take off thin film, leftover pieces are taken out, carry out shredding, focus on remove impurity, except micronic dust；
(4), mixing remove impurity: the regenerated fiber after shredding is fed mixed cotton system, is further mixed, dedusting and remove impurity；
(5), carding: use fixing point of comb flat caiding machine combing, and be laid in cross lapping mode by lapping machine
Net, forms the uniform regenerated fiber net meeting requirement through drawing-off；
(6), spun lacing, tentatively dry: carry out spun lacing by the positive and negative of the spun-laced machine regenerated fiber net to obtaining in step (3),
Dehydration, obtains preliminary spun lacing fleece, new type of safe emulsion is arranged spun lacing fleece with infusion process or foam method,
With post-drying, drying time controls at 80 ~ 95S, and temperature controls at 150 ~ 180 DEG C.Obtain spun-laced nonwoven fabric base fabric；
(7), be dried, finished product: the preliminary spun-laced nonwoven fabric hot rolled roller dryness finalization that will obtain in step (5), finally obtain into
The spun-laced nonwoven fabric of product, the temperature of hot roll is 205-235 DEG C, and rotating speed is 60-90m/min.
Owing to regenerated fiber has fiber length difference greatly, average length short (between 2mm-30mm), curling that fiber is straight
Few, short flannel, dust content are high, for improving the utilization rate of regenerated fiber in leftover pieces, reducing the damage to regenerated fiber and maximum
The removing dust of degree, when carrying out shredding, mixing, carries out shredding, mixing by non-holding shredding mixing machine.
Owing to regenerated fiber chopped fiber, short flannel are many, fiber is straight and crimps considerably less, and therefore cohesive force ratio is relatively low, causes
The intensity of the regenerated fiber net prepared is low, and very difficult smooth transfer strips, and becomes the cohesive force after netting with strong for improving regenerated fiber
Degree, when carding, sets up a fibre deposition roller for fixing point of comb flat caiding machine, and arranges adjustable row's suction
Valve, uses air-flow auxiliary to strip.
When carrying out spun lacing, for chopped fiber, the loss of short flannel in minimizing regenerated fiber, improve row yielding, use clamping pre-
Wet, sting in advance, the technique arrangement that multistage circle drum spun lacing combines, technique uses low pressure-middle pressure-low pressure-middle pressure alternately tangle
Technology, it is hyp slit pump orifice that optimization devises cross section, it is achieved mesolow negative pressure-pumping.
Spun lacing water recycles after treatment, and the multi-level water circulating treating system of employing includes vacuum draw, concentrates and scrape
The equipment such as the efficient residue machine of slag formula, micron order air-float filtration, sand filtration machine, metallic filter, pocket type accurate filter and water-delivery pump,
Selection, mechanical filter, air supporting, sand filtration, metal filtration and the filtering process of pocket type fine straining, filter the solid-state in backwater and oil preparation,

The preparation method of emulsion is as follows:
(a), remove ionized water, press through reverse osmosis membrane through height, be subsequently adding in insulating vessel, with ion exchange carry out once from
Son exchange, purifies deionized water, and improves its resistivity, make deionization resistivity of water be at least up to 8M Ω cm；
(b), in the case of logical nitrogen is protected, add in reactor 50～65% step (a) in the deionized water that obtains,
Heat and be incubated at 40～45 DEG C, then adding cationic emulsifier, mix and blend half an hour in reactor, be subsequently adding 20
～the deionized water of 25%, it is then heated to 45～47 DEG C and maintains, adding cationic emulsifier mix and blend half an hour, obtain
Emulsified solution；
(c), in emulsified solution, add 30～the initiator of 40% and remaining deionized water, mix homogeneously, be subsequently added second
Alkene monomer and VAM, carry out pressure polymerization, and be simultaneously added dropwise remaining initiator, when pressure polymerization, and reactor
Temperature controls at 70～85 DEG C, and gauge pressure is 0.15MPa～1.0Mpa, and with stirring, speed of agitator 600-700r/min, reaction
One hour, obtain preliminary emulsion；
D () reduces temperature of reaction kettle, control at 30～45 DEG C, is then slowly added into plasticizer, and with stirring, until the most mixed
Close, be eventually adding pH adjusting agent and neutralize, obtain finished emulsion.
