Although jade fiber has nice and cool characteristic, the temperature after the long-time dress of this two classes fabric can, along with constantly rising with skin contact, be difficult to the cooling characteristic that keeps lasting.
Summary of the invention
The object of the invention is for solving the problems of the technologies described above, a kind of tooling fabric with cooling function is provided, this fabric also has anti-ultraviolet function simultaneously.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs:
The tooling fabric with cooling, anti-ultraviolet function, is characterized in that, it is made by following methods:
(1) take cooling masterbatch as raw material, make section;
(2) section is dried: 150～170 ℃ of baking temperatures, 10～14 hours drying times, make to cut into slices below the moisture 30PPM of being down to;
(3) by manifold, section is carried out to spinning and make polyamide fibre base cooling fiber: section forms spinning melt thread in manifold after heating, melt thread is after the spinneret ejection of manifold, releases heat towards periphery immediately, thus make melt thread cooling curing, form fiber; Concrete technology is as follows: 1. heating, a plurality of temperature sections are set interval in manifold, and interval temperature raises successively gradually, and initial temperature is made as 220～230 ℃, and outlet temperature is made as 275～285 ℃, and it is 280～290 ℃ that the temperature of heating agent biphenyl is controlled; 2. cooling, the delay height setting of spinneret is 45～50mm, and it is 1200～1550mm that window height setting is blown in survey, and cross air blasting temperature is made as 22～27 ℃, and wind speed is controlled at 0.3～0.5m/s, and relative humidity is controlled at 65～75%;
(4) adopt match network spinning process that cotton fibre and polyamide fibre base cooling fiber are spun into mixed yarn: regular roving feeding 2.5～3.0g/10m, twist factor 120～125, spun yarn horn mouth centre-to-centre spacing 3.0～4.5mm, spun yarn twist factor 400～420, spun yarn front roller speed 135～155r/min;
(5) adopt the technological measure of " early opening, wefting insertion, warp tension are bigger late " to weave: loom opening time is selected in 335～345 °, and regulates stroke of harness frames by shed open furnishing isostension shed open, and shed open size is adjusted into 9～12mm;
Described cooling masterbatch formula is: PA6 is 65～70 weight portions, jade powder 10～15 weight portions, zirconium dioxide powder 3～5 weight portions, silicon-dioxide powdery 8～10 weight portions, stearic acid dispersant 1～3 weight portion, polystyrene dispersant 2～4 weight portions, low-molecular-weight wax dispersant 2～4 weight portions, titanate coupling agent 1～3 weight portion.
In technique scheme of the present invention, the quality of cooling masterbatch is directly connected to the quality of cooling fiber performance, and the present invention mainly selects cooling material, dispersant, coupling agent in cooling masterbatch, determines best master batch mix proportion scheme.The mineral that the selection nature of cooling material discharges cool feeling are permutation and combination in addition, be added in spinning process, and in fiber because including the ore (inorganic particle) of the cold element of release, reach the fast and instantaneous contact cool feeling of rate of heat dispation.But single ore physical characteristic is " heat absorption fast, heat radiation also fast ", for realizing long contact cool feeling, must realize the absorb heat characteristic of slow rapid heat dissipation of fiber.Therefore need to carry out cooling material powder compositely, by utilizing instantaneous coolness, zirconium dioxide and the silica body surface area of jade large, the characteristics such as rapid heat dissipation, realize the cooling-down effect of final products.Dispersant, coupling agent etc. are also larger to the Influence of production of cooling masterbatch.
In technique scheme of the present invention, cooling masterbatch be take PA6 as main body, and the hygroscopicity of itself cutting into slices is better, adds after cooling powder, has increased the moisture pick-up properties (this is also the importance that coolness embodies, and the moisture content of fiber is higher, and cool feeling degree is also more obvious) of section.But the existence of moisture content can make cooling section be hydrolyzed in spinning process, the silk that causes wafing, broken end, can not spinning in the time of seriously; In addition, a small amount of moisture content can at high temperature form steam bubble, is clipped in strand, becomes weak link, causes equally waft silk, broken end etc. when serious.Therefore must strengthen chip drying.The present invention requires after cooling section drying operation, moisture being down to below 30PPM.
In technique scheme of the present invention, the base polymer PA6 fusing point of cooling masterbatch is 225 ℃, but makes its rheological property and pure PA6 have larger difference because cooling masterbatch adds a large amount of time micron mineral powders, and both best spinning temperatures have different.The apparent viscosity of cooling masterbatch is high.In the trial production of composite fibre, the time of staying of cooling masterbatch melt in pipeline is longer.In order to guarantee that two components compound tense viscosity differences in assembly approaches, to improve the viscosity of its section on the one hand, provide larger viscosity to fall space, its melt is approached at the rheological property of assembly and the rheological property of PA6 melt, to reduce spinning temperature, to reduce its degraded simultaneously.Therefore the present invention has taked the mode heating up gradually and heat in multistage interval.
In technique scheme of the present invention, in spinning process, cooling forming is an important step.Select a suitable cooling forming condition, and to keep it stable be the important means that reduces fiber yarn unevenness, improves fiber quality.Spinning melt thread after spinneret ejection, medium releases heat towards periphery immediately, thus make melt thread cooling curing, form fiber.The process of the heat exchange between melt thread and air cooling medium directly affects the VELOCITY DISTRIBUTION of dynamic analysis of spinning, the stable and curing area of the uniformity of fibre structure, configuration of surface stable etc.So select suitable, stable cooling condition, the cooling fiber tool that carries out smoothly and finally obtain high-quality in cooling fiber forming process be of great significance.The wind speed of cross air blasting, wind-warm syndrome and rheumatism larger, too high, the too low uniformity variation that all can make tensile property and the fibre structure of fiber of quality impact on cooling forming process and strand, thus fiber quality affected.By test of many times, cross air blasting Temperature Setting is at 22～27 ℃.Same reason, cross air blasting wind speed should not be too high, and in cooling fiber spinning process, we control cross air blasting wind speed at 0.3～0.5m/s.
The height of cooling fiber content directly has influence on the quality of fabric cooling-down effect, and content is higher, and finished product fabric cooling-down effect is more remarkable, but increase cooling fiber content, can increase production cost and affect feel.Therefore need to carry out preferably, making final finished fabric there is good cooling-down effect to cooling fiber and cotton fiber blending ratio, can save production cost again.
In technique scheme of the present invention, as tooling fabric require that cloth cover is clear, stiffness better, cloth cover filoplume is few etc., and adopts Siro-spinning can well reach above-mentioned effect.With Siro-spinning, because two rove are simultaneously drafted, play certain amalgamation, two coring bars make up mutually, improve bar dry, reach the object that reduces details, slubbing.Meanwhile, the yarn after two velamen drawing-offs is in twisting process, and single yarn adds after a little twist, then mutually, twist and be combined into one and match doff, like this filoplume winding on single yarn is entered in yarn, and then improves resultant yarn plumage.Match doff has strand feature, and fiber alignment is regular, so yarn strength is also very high.It is that two rove feed Spinning Draft Zone simultaneously that match network spins, if will be spun into the yarn of certain fineness, just must make regular roving feeding significantly reduce.Regular roving feeding is too small, and can make rove in unwinding process, produce unexpected elongation even and interrupt, thus must increase roving twist factor, to increase the intensity of rove, but the excessive rear road spinning process that can affect again of roving twist factor.Therefore, in spinning process, adopt that regular roving feeding is partially light, twist factor design bigger than normal.
Horn mouth centre-to-centre spacing is one of important technical parameter of spinning of match network, and horn mouth centre-to-centre spacing has been determined the distance of two parallel feeding draw zones of rove.Strand spacing is larger, and it is more obvious that match network spins advantage, but spacing also will be subject to the restriction of spun yarn roller width, and spacing is crossed conference makes yarn in the limit of drawing-off roller portion, affects the purchase capabilities of roller to sliver, thereby affects yarn quality.
Fibre cohesion between cooling fiber and cotton fiber is general, and the twist that match network spins on single yarn is lower, causes interfibrous cohesive force poorer, more easily occurs the generation of single broken end phenomenon.Therefore,, when spinning cooling fiber and cotton fiber spun yarn, twist factor should processing bigger than normal.While is very little because match network spins regular roving feeding, and the drafting multiple that the single yarn of draw zone is subject to is larger again, easily causes sliver easily to break end before twisting, therefore need reduce spun yarn spinning speed.
Clear for guaranteeing to weave opening, reduce staplings, adopt the technological measure of " early opening, wefting insertion, warp tension are bigger late ".Because yarn strength is larger, therefore can suitably improve weaving tension in weaving, reduce the elongation differential of shed open levels warp thread, while being conducive to pneumatic picking, shed open is clear.Loom opening time should be early, generally be selected in 340 ° of left and right, and regulate stroke of harness frames by shed open furnishing isostension shed open as far as possible, so both guaranteed the definition of shed open, the difference of levels warp tension while having reduced to a certain extent opening again, shed open size is 10mm.
Above-mentioned time Jun Yi°Wei unit, the described time refers to the moment that forms this wefting insertion angle, as, 85 ° of injecting times, refer to, moment when wefting insertion angle is 85 °.
As technique scheme preferably, after step (5), also has staining procedure, adopt neutral fixation activity to dye in fabric cotton, the means that neutral dye dyes cooling fiber in fabric realize dyeing, the realization that adds of polyamide fibre stain resistance prevents the dyeing of neutral fixation reactive dye to cooling fiber, dyeing temperature is 90～100 ℃, dye bath pH6.8～7.2, concrete dyeing recipe is as follows: neutral fixation reactive dye and neutral dye are enough, levelling agent 0.3～0.6g/L, stain resistance 1.5～2.5g/L, pH buffer is in right amount to control dye bath pH6.8～7.2, glauber salt 15～30 g/L.
In technique scheme of the present invention, because fabric is cooling fiber (polyamide fibre)/cotton fiber blending product, cooling fiber can dye with dispersion, acid (neutrality) and reactive dye, and cotton fiber is generally only used reactive dyeing.For reducing energy consumption, reduce the tediously long disadvantage of two bath process operation, dyeing fabric of the present invention adopts active and neutral dye one bath one-step method dyeing.For making cooling fiber/cotton fiber blended yarn weaved fabric even dyeing, color and luster is plentiful pure.Project team is preferred from the technological parameters such as dye selection, dyeing temperature, Value in Dyeing Process and stain resistance, has determined optimum dyeing process program.In dye selection, considering under the conditions such as level-dyeing property, color fastness, depth the neutral fixation reactive dye of the preferred Japanese chemical drug Kayacelon of company and neutral dye; The objects such as dye cotton with neutral fixation reactive dye under neutral environment, neutral dye dyes cooling fiber, realizes even dyeing, dyeing color fastness height.The height of dyeing temperature has a significant impact tinctorial yield, but dyeing temperature is higher than after 120 ℃, and cooling fiber brute force sharply declines.Consider poststaining temperature and be controlled at 100 ℃ of left and right.Value in Dyeing Process after deliberation neutral dye changes not quite at 5～8 o'clock dye levels, consider that neutral fixation reactive dyeing is 7 o'clock the bests in pH value, so Value in Dyeing Process elects 7 as.
