4sn) 2%; White oil 10%; This lysate is solubilized spandex; In dissolution process, different according to flower pattern, lysate is different from the quality proportioning of dyeing assistant sodium alginate paste, corresponding bar magnet (scraper) is also different with pressure, and needed for thin stem class small size flower pattern, lysate is less, and needed for the flower pattern of bulk face, lysate is more, therefore, thin stem class flower pattern: the mass ratio of lysate and sodium alginate paste is 1:1, and bar magnet selects No. 10 or No. 12,80% magnetic force or 45-50cm scraper; Block flower pattern: the mass ratio of lysate and sodium alginate paste is 1:1.5, bar magnet selects No. 15-20,90% magnetic force or 50cm scraper; Large area flower pattern: the mass ratio of lysate and sodium alginate paste is 1:2, bar magnet is No. 25,100% magnetic force or 55cm scraper, after lysate and sodium alginate paste stir, adopt the neat agate rotary screen printing machine wholly computer controlled of Austria, lysate and sodium alginate paste be coated with in elasticity BLENDED FABRIC, pressure size along with flower pattern by thin stem to block, face, ascending preparation, to adjust lower slurry amount and the osmotic effect of lysate.
1. pre-treatment process
In order to improve behavior in service during spinning, in the weaving process of elasticity BLENDED FABRIC as spandex or its BLENDED FABRIC, employ silicone oil lubricant and other auxiliary agents, As time goes on these auxiliary agents can cause fiber yellowing by natural degradation, the flexibility decrease of fabric; Meanwhile, elastic fiber fabric can be formed " cold setting " in long term storage, makes fabric in aft-loaded airfoil, produce the permanent wrinkle that cannot eliminate.So elasticity BLENDED FABRIC, except reducing except the storage time, to be the more important thing is after weaving open width package after open-width immediately, is avoided the chance producing backfin trace; After weaving end, spandex can produce certain internal stress, and preboarding then by this stress of stretched and relaxed elimination of fabric, makes the size of fabric fully stable, avoids fabric to occur permanent crease in aft-loaded airfoil.If form coil when cylinder is weaved, second coil is on the left side of first coil, and so entering cloth direction during preboarding also should 7% ~ 10% (relative fabric width) before the left side, makes to be consistent into cloth direction and finished product twist.
Therefore, best preboarding scheme is: lax → decatize → overfeeding preboarding → (entering fabric pre-treatment → setting → stamp).Because not having decatizing apparatus, direct squezzing enters setting in most of dye-works, when temperature is below 10 DEG C, fabric easily produces folding line.In technical solution of the present invention, elasticity BLENDED FABRIC is formalized after first being relaxed by steaming box again, satisfied effect can be obtained, setting temperature is unsuitable too high, otherwise can make fabric yellowing, therefore, preboarding is wanted first to formalize after steaming box is lax again, preboarding temperature is 185-190 DEG C, and the preboarding time is 45-60 second.
2. the type approval requirements of semi-products
The setting of semi-products must be carried out according to intrinsic technique, in general formalize fabric width comparatively Fabric width be about 3% ~ 5%, warp-wise shrinkage controls within the shrinkage of finished product requirement, and the elongation of patch equals magnification ratio when original text retouched by design.If this elasticity BLENDED FABRIC is single knitting cloth, so also need the control of oar trimming and best twist, to reduce the stamp skew of weft produced because of twist, the width on slurry limit is about lcm, breakpoint slurry is for good, should not be too thin or blocked up, thin do not have due effect, the too thick printing quality then affecting nearly selvedge.3. lysate is to the dissolution process (for ROTARY SCREAM PRINTING) of elasticity BLENDED FABRIC
Selecting heat shrinkage resin or the patch of patch slurry according to the performance of the elasticity BLENDED FABRIC containing spandex, regulate into cloth edge guide, edge spreader, dust catcher, regulate into cloth tension force, is standard containing the elasticity BLENDED FABRIC patch tension force of spandex with minimum.Therefore, in the ROTARY SCREAM PRINTING process of elasticity BLENDED FABRIC, stamp speed is comparatively suitable with 35 ~ 40m/min, the too fast speed of a motor vehicle is unfavorable for the infiltration of lysate and the control of product quality, simultaneously, the pattern return of ROTARY SCREAM PRINTING is subject to certain restrictions, direct system with PLATE SCREAM PRINTING unlike the return of ROTARY SCREAM PRINTING, must according to the ratio of having amplified, strict regulation speed, otherwise due to the changeability of knitted cloth patch size, cause the product flower pattern size distortion after print lysate, produce the difference between product batches, therefore, stamp speed should be fixed and should not be too fast.
4. stamp post-drying
Strict control drying room temperature, the bake out temperature of COAT PRINTING is 140-145 DEG C, makes binder generating portion be cross-linked while oven dry; The bake out temperature of printing with reactive dye is 135-140 DEG C, and both sides are dried evenly, and during printing with reactive dye, dewing of preferably spraying before entering rapid steamer, makes the cloth surface temperature of elastic fiber fabric be unified in room temperature state, keeps uniformity and the integrality of tinctorial yield.
5. evaporate and wash
In technical solution of the present invention, evaporate and carry out in continuous steaming machine, steam flow is 2t/h, and temperature is 103-105 DEG C, and the time of evaporating is 10min; Entering cloth tension force can drive cloth to enter rapid steamer; Washing adopts loose formula open width and loose formula rope form continuous washing, adopts shower water to wash when open width state.
Due to cylinder steam box evaporate time, the elastic fiber fabric hung up properly not only can weft direction stretch distortion in damp and hot evaporating, the meeting also had is dragged at the bottom of case, is exaggerated the drawback that cylinder steam box easily produces the upper and lower depth, causes that to evaporate color development irregular, therefore, in the present embodiment technical scheme, it is good that elasticity BLENDED FABRIC continuous steaming machine evaporates comparatively cylinder steam box, when loop steamer evaporates, to note into cloth tension force little equally, enter rapid steamer so that elastic fiber fabric can be driven and be advisable; Enter cloth smooth, the cloth cover of elasticity BLENDED FABRIC can not fold, otherwise can produce faults such as cutting marks, tow out in the process of evaporating.
The more general knitted cloth washing of elasticity BLENDED FABRIC washing more will note the stressed problem of the warp-wise of whole water-washing process, therefore loose formula open width Jia Songshi rope form continuous washing is current reasonable knitting rinsing machine, the elastic fiber fabric of open width state passes through shower water, can make with comparalive ease the slurry on fabric expanded, wash away alkaline agent on fabric and a part of loose colour after enter rope form and soap or reduction cleaning process, good water washing effect can be obtained.
6. the elasticity BLENDED FABRIC after finished product sizing rinse dehydration, fabric width requires to reduce much than finished product, on boarding machine, once soft setting does not often reach the requirement of anticipation, needs at loose formula drying machine drying, allows elastic fiber fabric have sufficient time overfeeding to be shaped.The too fast setting speed of a motor vehicle can make elastic fiber fabric produce the out-of-flatness state of tight, the middle pine in both sides, and the unfavorable spandex stamping lysate dissolves.Therefore, in this programme, first elastic fiber fabric is dried on loose formula dryer before setting, allow its natural preshrunk, then overfeeding sizing, sizing speed is about 20m/min, setting temperature is 185-190 DEG C, make to stamp in the elasticity BLENDED FABRIC of lysate, elastomer (spandex) dissolves and follows the string, form sunk part, and the intertexture coil not stamping lysate is (cotton, fiber crops, bamboo, it silk, model, wash/cotton) be returned to larger situation, thus give prominence to form bossing on cloth cover, sunk part and bossing form translucent design, cloth cover is allowed to have anaglyph, the fabric obtained is elastomer and dissolves fabric.
In the present invention, elasticity BLENDED FABRIC is spandex with cotton, fiber crops, bamboo, sky silk, model, wash/cotton is woven into.
The elastomer obtained taking technique scheme dissolves the fracture strength of fabric, water-fastness/WASHING COLOR FASTNESS is tested, and the deformation degree of dissimilar pattern after washing on the fabric that in contrast employing the present invention prepared by technical scheme, the results are shown in Table 1.
Under table 1 different disposal condition, elastomer dissolves the performance test results of fabric
Can find out, elastomer after technical solution of the present invention process dissolves fabric, not only painted homogeneous, after repeatedly washing, the flower pattern on this fabric is still very regular, stereoeffect is good, meanwhile, whole production process can be applicable on existing printing equipment, without the need to adding too much equipment, production control is convenient, and cost is lower.
