Abstract
The invention discloses a manufacturing method for kapok phase-change material that includes the following steps: taking preprocess to 5-100% kapok fiber, 0-95% cellulose fiber, 0-90% other fiber through refining technology of cotton fabric, dipping into phase-change finishing agent for 1-5 hours, extruding the rest finishing agent, pre-drying for 3-10 minutes at 40-100 degree centigrade, baking for 1-5 minutes at 80-160 degree centigrade, taking soaping for 10-20 minutes at 60 degree centigrade, cleaning by water. The benefit effect of the invention is that it achieves optimal temperature adjusting function for kapok, saves refrigeration and heating energy, improves the anti crease and humidity transmission capability.
Description
Technical field
The present invention relates to the manufacture method of a kind of phase transformation kapok textile material (fiber, yarn, fabric), particularly relate to a kind of chemical manufacturing method that in the earth environment temperature range, has the kapok textile material of phase-changing and temperature-regulating function.
Background technology
One of phase-change material big the application is the heat-accumulation temperature-adjustment product at present, and along with the sternness of energy scarcity, environmental issue, the heat-accumulation temperature-adjustment product more and more is subjected to domestic and international attention.The heat-accumulation temperature-adjustment textiles is exactly the novel high-tech textiles that adopts the development of Chemical Physics method, generally be to meet hot and cold back by textile fabric surface or the inner phase change material that contains solid-liquid reversible transition takes place to absorb, emit heat, and then show and delay variations in temperature or temp regulating function.In certain temperature range, this class textiles can be according to variation of ambient temperature free adjustment textiles internal temperature, and promptly when ambient temperature raise, textiles absorbed heat or storage power, slowed down the textiles environment temperature and raise; When ambient temperature descends, but the textiles release heat, and it is less relatively that ambient temperature is descended.This kind textiles can be used for fields such as curtain, wall paper, automotive interior material, clothes, can reduce the heat loss of micro climate in indoor or the clothes winter, can slow down summer indoor or the interior micro climate temperature rising of clothes, the energy of saving refrigeration and heating provides more comfortable living environment.
Bombax cotton is a kind of native cellulose fibre with bigger serface, big hollow structure, and degree of hollowness is used to make phase-changing energy storage material and all has more advantage than existing any fiber up to 80～90%.Have research to adopt the technology of PEG crosslink finishing cotton textiles or cotton blended fabric at present, exist the adjusting temperature range can not satisfy defectives such as actual needs, arrangement back appearance of fabrics is sticky, strength loss is big, practical value is relatively poor, so seldom be used.And the kapok phase-change material that adopts the present invention to make, in the rate, thermoregulation range is desirable more on the increase finishing agent increases, and strength loss is not more than 35%, and 50% after putting in order much smaller than pure cotton fabric has more application value.
Summary of the invention
Technical problem to be solved by this invention provides a kind of manufacture method of kapok phase-change material, to remedy the deficiencies in the prior art or defective, meets the demands of production and living.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of manufacture method of kapok phase-change material comprises the steps:
(1) composition of base material and quality percentage composition thereof are as follows:
Bombax cotton 5-100%
Cellulose fibre 0-95%
Other fibers 0-90%;
(2) phase transformation finishing agent preparation
Phase-change material: the degree of polymerization is 400～2000 solid polyethylene glycol
Crosslinking agent: 2D resin four-functional group crosslinking agents such as (DMDHEU)
Catalyst 1: mol ratio is 10～15: 1 the moisture inorganic salts and the mixture of citric acid
Catalyst 2: inorganic salts
With the mass percent of above-mentioned material by polyethylene glycol 20%～80%, crosslinking agent 15%～25%, catalyst 1 be 2%～8%, catalyst 2 is 3%～9%, water is 0～60% mixed, in 60～80 ℃ water-bath, stir, promptly make the phase transformation finishing agent;
(3) manufacturing technique
Adopt the refining treatment technology of COTTON FABRIC that base material is carried out preliminary treatment, then immerse the phase transformation finishing agent that step (2) makes, dip time is 1-5 hour, the rod that rolls with conventional arrangement machinery will not form crosslinked unnecessary finishing agent and extrude again, under 40-100 ℃ condition preliminary drying 3-10 minute, baked under 80-160 ℃ the condition 1-5 minute, and soaped under 60 ℃ 10-20 minute with the bath raio of 2g/L, the clear water rinsing is clean then.
As optimized technical scheme: described cellulose fibre comprises one or more in cotton, flax fibre, viscose or day silk.
Described other fibers comprise one or more in terylene, polyamide fibre, acrylic fibers, PTT and the wool fibre.
Described crosslinking agent is 2D resin or modification 2D resin.
Described moisture inorganic salts are one or more in magnesium chloride hexahydrate, Iron trichloride hexahydrate, crystalline potassium chloride or the sal glauberi, and described inorganic salts are one or more in sodium chloride, potassium chloride, sodium sulphate or the potassium sulfate.
The invention has the beneficial effects as follows: the optimal temperature adjustment function of having realized cellulose fiber peacekeeping yarns such as kapok, fabric, can alleviate the variation of ambient temperature at textiles place, save the cooling and warming energy, perhaps for human body provides more comfortable living environment, improved the wearability such as crease-resistant, saturating wet of fabric simultaneously.
Design of the present invention is such: when polyethylene glycol (PEG) was carried out cold cycling treatment, the transformation of certain phase can take place in its supramolecular structure, thereby changed macroscopic property and have special heat-accumulation temperature-adjustment performance.The outstanding behaviours of this heat-accumulation temperature-adjustment performance absorbs heat or storage power when high temperature, environment temperature releases energy when reducing, and heat is emitted.Discover, PEG except having preferably the active and low temperature phase change of heat, also can with textile fabric generation physics or chemical combining, the possibility that is added on the textiles is arranged, and then widens the performance advantage of textiles.
The method of giving fabric phase transformation performance mainly contains three kinds of completion method, chemical method and microcapsule methods.Wherein completion method fiber sealing two ends technical difficulty is big, and actual production has certain difficulty, and water-wash resistance is poor; The microcapsule method complex process, the cost height.The present invention is from the development of new natural fabric, and the angle that makes full use of natural resources is set out, and adopts the method for chemical crosslinking with crosslinking agent DMDHEU that PEG is crosslinked at the bombax cotton surfaces externally and internally, makes phase-change material.The citation form of reaction is as follows:
The thinner bombax cotton specific area of fineness is bigger, kapok is the human at present high doughnut of finding the thinnest, that also can directly use, except can with finishing agent generation chemical crosslinking, can also obtain better physical and adhere to, this is to select bombax cotton to make the major reason of base material.
