The test result of the index of correlation of flocculus and common chemical fibre flocculus sees the following form among above-mentioned four embodiment:
Annotate: when washing size rate of change, the test of warming rate, flocculus coats 13.1 * 13.1 133 * 94 polyester-mixed cotton cloth outward
The flocculus that data can obtain among the present invention from table is compared with common chemical fibre flocculus, warp direction stretching ultimate strength height, and warmth retention property is good, and washing back size changing rate is less.Simultaneously, the every index among the embodiment among the present invention 4 is better than other embodiment.
The present invention be advantageous in that:
When selecting the flocculus material, consider warmth retention property, resilience, the comfortableness of flocculus, materials are elected hollow mercerising polyster fibre as, and hollow mercerising polyster fibre simulate wool, have characteristics in light weight, that bulking intensity is high, warmth retention property is good, therefore hollow mercerising polyster fibre has higher crimpness, and stretcher strain and diastrophic recovery capacity can be improved the compression recovery performance of flocculus.Ordinary polyester fibre strength height, elastic recovery be good, do not go mouldy, anti-damaging by worms, and it is one of best fiber of hydrophobicity in the synthetic fiber, and regain has only 0.4%, 230～240 ℃ of softening points, 255～265 ℃ of fusing points; Have good chemical resistant stability, as weak acid, weak base and common oxide bleaching agent, therefore warming main material is selected hollow mercerising polyster fibre and ordinary polyester fiber.
The hot melting cohesion fiber has fusing point and shrinks little, good fluidity, the easy advantage of bonding when low, softening, can make the flocculus product have good DIMENSIONAL STABILITY and washability, has realized need not self adhesion technique of chemical adhesive.The more employing of hot melting cohesion fiber be low-melting fiber, as low-melting polyethylene, polypropylene fibre and core-skin composite fiber.The low melting point core-skin composite fiber refers to that the different polymer of two kinds of fusing points is distributed in the fiber that become among the same fiber with skin-core structure, and the cortex polymer fusing point is low and flexibility good, and core layer polymer fusing point and intensity are all high.Make low-melting cortex polymer fusing at a certain temperature, in fiber web, play the effect of bonding connection fiber, the polymer that sandwich layer fusing point and intensity are high plays in bonding and supports fibroreticulate effect, makes the flocculus of making that higher elastic recovery and adhesive fastness be arranged.By the combination of polymers form, the low melting point core-skin composite fiber can be divided into polyethylene/polypropylene fiber PE/PP, polyethylene/polyester fiber PE/PET, alkali soluble polyester/polyester fiber COPET/PET etc., wherein alkali soluble polyester/polyester fiber COPET/PET cortex fusing point is minimum 110 ℃, higher 256 ℃ of sandwich layer fusing point, under certain heat setting temperature, rising along with temperature, can make the fully fusion of cortex of alkali soluble polyester/polyester fiber COPET/PET, strengthened the flowability of tack coat simultaneously, make in the flocculus various fiber surfaces in conjunction with fully, cohesive force increases, the performance of flocculus just rises, but the thermal degradation of fiber molecule can take place when temperature is too high, flocculus color meeting flavescence, thus the flocculus performance descends.Find in the pilot sample process, if it is not under the very high situation that the temperature of HEAT SETTING is selected, can make alkali soluble polyester/complete fusion of polyester fiber COPET/PET cortex by the speed that reduces fibre web, and certain flowing arranged, therefore our alkali soluble polyester/polyester fiber COPET/PET core-skin composite fiber of selecting for use, under 120 ℃～145 ℃ conditions of heat setting temperature, produce flocculus when reducing web speed to 25～35m/min, the inside and outside meldable fibre of fiber web can better be melted, fiber adhesion has guaranteed that fully the integral body bonding of flocculus is powerful together on every side.256 ℃ of higher sandwich layer fusing points, in process, guarantee the rigidity of fiber, stablize the flocculus size, make flocculus that resilience is preferably arranged simultaneously, so medical comforter batt tire core flocculus adopts low melting point alkali soluble polyester/polyester fiber COPET/PET fiber, its cortex fusing point is low, easily mixes with other fibers, has outstanding bond properties, good washability and stable machinability.
With comforter batt flocculus raw material components through mixing, shredding, removal of impurities, combing, one-tenth net, lapping, hot melt add fixed, flatiron is put in order, is cut, checks, packs series of processes, the flocculus of making 250g/m2 carries out campaign; With the increase of doughnut content, warming rate increases, and warmth retention property strengthens; Along with the increase of alkali soluble polyester/polyester fiber COPET/PET fiber, scaffold fibers increases, and the space increases between fiber, and permeability increases, and still air content reduces, and causes warming rate to descend; Ratio increase along with alkali soluble polyester/polyester fiber COPET/PET binder fiber, the brute force of flocculus also increases, but when the COPET/PET fiber increased to 30% left and right sides, the bonding probability of the alkali soluble polyester in the flocculus/polyester fiber COPET/PET fiber and main fibre but no longer increased.Therefore, should choose reasonable alkali soluble polyester/polyester fiber COPET/PET fiber content, among the present invention we to have selected the fiber quality percentage of alkali soluble polyester/polyester fiber COPET/PET be 25%, when the fiber quality percentage of alkali soluble polyester in the flocculus/polyester fiber COPET/PET greater than 25% the time, bonding probability between the fiber no longer increases, the brute force value of flocculus finished product, size changing rate and the feel after the washing have been had influence on, powerful value diminishes, washing back size instability, change in size is bigger, and feel is harder; When the fiber quality percentage of alkali soluble polyester in the flocculus/polyester fiber COPET/PET less than 25% the time, the brute force that bonds between fiber and the fiber can not satisfy the brute force value of finished product flocculus, while also can have influence on the DIMENSIONAL STABILITY after the washing, brute force is big inadequately, the size instability, rate of change is bigger.
