Prepared by base polyurethane prepolymer for use as: first acid adding stirring and adjusting pH value after the first polyalcohol 45 parts and the second polyalcohol 50 parts mixing, to 5.0-6.0, is then added 20 parts of MDI isocyanates, 8 parts of additives react 15min and obtain base polyurethane prepolymer for use as at temperature is 45 DEG C; Described first polyalcohol is the polymer of ethylene glycol and propylene glycol, and degree of functionality is 3, hydroxyl value 69mgKOH/g; Described second polyalcohol is the polyol of trimethylolpropane and epoxy butane, and epoxy butane content is greater than 60%, hydroxyl value 12mgKOH/g; Described additive is normal butane;
Prepared by polyaminoester emulsion: add after stirring pre-emulsification 8min in the aqueous solution of 5 parts of organosiloxane copolymers, 8 parts of emulsifying agents, 3 parts of magnesium monohydrogen phosphates and 50 parts of deionized water compositions, adopts homogenous disperse machine dispersion 2min to form miniemulsion; Emulsifying agent is be the lauryl sodium sulfate that mixes of 3:1 and neopelex according to mass ratio;
One-step solidification forms preliminary microcapsules: in miniemulsion, add 6 parts of N methyldiethanol amines, natural lavender essential oil that 12 parts of volume ratios are 8:1 and camomile essential oil be 800 revs/min in stir speed (S.S.) and stir 2min and obtain preliminary microcapsule solution;
Regelate forms stable microcapsules: reduce rotating speed to 700 rev/min, add liquid amido organosilicon and react 12min at 55 DEG C, the volume ratio of liquid amido organosilicon and described preliminary microcapsule solution is 1:50, then slowly cools to room temperature discharging, obtains nanometer Lavender essential oil microcapsule.
Below the rate of perviousness of goods and measure wicking height are detected:
(1) tester of poisture-penetrability and method
Fabric moisture-penetrability index is rate of perviousness.Rate of perviousness refers under fabric two sides exists the condition of constant water vapor pressure respectively, by the water vapour weight of fabric per unit area in the stipulated time.
Laboratory apparatus: this test adopts the computermatic fabric moisture transmission instrument of YG601-1 type.Test condition: be 38 DEG C in temperature, relative humidity is 90%, and air velocity is test under the condition of 0.3 ~ 0.5m/s.Experimental technique: five samples all got by often kind of sample, all samples damping 24 hours in incubator before test.Loaded by hygroscopic agent in clean dry cup, hygroscopic agent loading height is apart from sample lower surface 3 ~ 4mm place, and makes it become a plane.
Be placed on upward on cup by the knitted fabric product sample test surfaces of embodiment one-embodiment three, load onto packing ring and pressure ring, screw on nut, composition test group is fit.Be placed on fabric balance by cup rapidly and weigh, recording quality, then builds.Load weighted cup is put into chamber, takes out after 1h, claim its quality, record data.The most often organize the mass change before and after assembly moisture absorption.Utilize formula (3-1):
(1-1)
Wherein U is rate of perviousness, and G is the weight (mg) that after a period of time, hygroscopic agent increases, the disengagement area (cm of t to be sample storage time (min), A be steam
2).
Test result is in table 1:
Test result illustrates: rate of perviousness is large, and show that fabric is strong through the ability of steam, then poisture-penetrability is good, and therefore, the poisture-penetrability of fabric embodies the nice and cool performance of fabric.And the rate of perviousness of conventional common goods is generally less than 19%.Illustrate that knitted fabric goods poisture-penetrability of the present invention is good, dress is ventilative.
This specific embodiment is only explanation of the invention; it is not limitation of the present invention; those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this description, as long as but be all subject to the protection of Patent Law in right of the present invention.
