Brief description of the drawings
Fig. 1 is the flow chart of the production technology of spunlace non-woven cloth in the embodiment of the present application；
Fig. 2 is the flow chart of cold drift step in the embodiment of the present application.
Embodiment
The application is described in further detail below by embodiment combination accompanying drawing.
The production technology of spunlace non-woven cloth given by the present embodiment as shown in figure 1, comprise the following steps,
S10, lapping
Raw cotton fiber after opening or cleaning, combing is passed through into lapping machine and carries out lapping, forms web.
S20, spun lacing
Web is subjected to spun lacing by high pressure cascade, forms spunlace non-woven cloth.
S30, cold drift
Spunlace non-woven cloth is handled through cold drift.Specifically as shown in Fig. 2 including：
S31, squezzing；
Non-woven fabrics after spun lacing is subjected to squezzing processing through high-capacity squeezer, reduces its moisture so that water in non-woven fabrics
Point content is down to 50%-100% by 150%-400%.
S32, immerse bleach activator；
Non-woven fabrics after squezzing is immersed into bleach activator.Because non-woven fabrics has been subjected to step S31 squezzing processing, its water imbibition
Strengthened, be advantageous to the absorption of bleach activator.Wherein bleach activator includes 12.5g/l nonionic penetrant, 12.5g/l stabilization
Agent, 2.5g/l metal coupler free, and 30g/l caustic soda, 60g/l hydrogen peroxide.Bleeding agent composition is fatty alcohol polyoxy alkane
Alkene ether；Stabilizer is stannous salt, anthraquinone and DTPA compound ligand, phosphonate, colloidal solution, the oxygen of hydroxycarboxylic acid and tin compounding
Change tin and organic phospho acid, the colloidal solution of sodium nitrate compounding；Metal coupler free is phosphonate ester compound.
S33, clot；
The non-woven fabrics clot of bleach activator will be added.
S34, cold dome；
Non-woven fabrics after clot enters in cold dome room, at normal temperatures cold dome 2-12 hours.
It is cold drift compared to traditional handicraft drift pot boil drift water consumption it is few, power consumption is low, and energy-conserving and environment-protective.
S40, washing
Non-woven fabrics after cold dome is subjected to spray washing using 60-95 DEG C of hot water, then alternately entered by squezzing and washing
Row is multiple, washes away the bleach activator of residual.
Can efficiently it be washed by rotary drum under 90 DEG C of water temperatures in rinsing machine, then under 95 DEG C of water temperatures bank up shower water successively
Wash 11 minutes, 80 DEG C of water temperature rotary drums are efficiently washed, and 60 DEG C of water temperature rotary drums are efficiently washed, then neutralize acid-base value to PH5.5, then are passed through
Liquid carrying rate is down to 60% and adds functional finishing agent (three anti-arrangements, anti-alcohol, anti-blood, hydrostatic pressure resistant) by high-capacity squeezer, whole
Non-woven fabrics after reason is through padding machine squezzing to liquid carrying rate 86%.Wherein, water consumption 8-12L/kg, ton cloth water 8-12 tons are washed；Water
Washing machine rotary drum rotating speed is 30-60m/min, and the nip pressure of padding machine is 12N/mm, or 40N/mm.Non-woven fabrics grammes per square metre is relatively low, big portion
Point in 30-50g/ ㎡, fraction 50-120g/ ㎡, in order to ensure low grammes per square metre non-woven fabrics cloth cover breadth, lines etc. not by water washed
Journey influences, and washes and is carried out under the conditions of low-tension, that is, face tension is 0-50N when washing.Washing carries out three anti-arrangements simultaneously, full
Podiatrist is with operation dress functional requirement.
This step can also use drift pot washing：Nonwoven fabric roll after cold dome is put into drift pot, handed over using being outflowed in hot water
Wash 1-2 i.e. completion washing for washing, then normal temperature and take the dish out of the pot, carry out dehumidifier, pump the excessive moisture in yardage roll, the rate control of band water
Within 150%.
Non-woven fabrics through this technique productions, fibre damage is relatively low, and strength loss is low, compared to the de- bleaching process of original, raw cotton fiber
Weight-loss ratio reduces by 1.5%, CIE (International Commission on Illumination) whiteness and can reach more than 92, and brightness reversion whiteness reaches more than 85, cloth cover without
The impurity such as cotton seed hull remain, no surface-active substance residual, and cloth cover is soft.
S50, drying
Clot is stored after non-woven fabrics drying after step S40 is washed.
The production technology for the spunlace non-woven cloth that the application provides, drift is taken off using online cold drift, drift phase is boiled with existing drift pot
Than water consumption can reduce 85%, and power consumption reduces by 70%, greatly reduces production cost, and energy-conserving and environment-protective；Spun lacing and cold drift
Step is carried out continuously, and improves production efficiency, and avoids boiling after non-woven fabrics clot drifting out the problem of existing bleaching is uneven.
Above content is to combine the further description that specific embodiment is made to the application, it is impossible to assert this Shen
Specific implementation please is confined to these explanations.For the application person of an ordinary skill in the technical field, do not taking off
On the premise of conceiving from the present application, some simple deduction or replace can also be made.
