Description
Technical field
The present invention relates to a kind of preparation methods of water-fastness polyurethane-type moisture control agent, belong to textile and chemical technology
Field.
Background technique
In recent years, as quality of life improves, people are higher to the pursuit of body-building, moulding, are engaged in the movement of outdoor activities
The more, sports fans tend to natural fiber clothing, especially pure cotton fabric, soft comfortable, natural environmental-protective, nursing letter to person
Single, durable, by pro-gaze.
It is known that: natural fiber, by taking cotton as an example, moisture pick-up properties is good, comfortable and easy to wear, and fiber regain is about 8%, inhales
Moist good, when human body amount of sweat is larger, cotton fiber can be expanded because of moisture absorption, and fibre section increases 40-50%, and fabric becomes tight
Close, stomata obstruction, interferes skin to exchange with the heat exchange between external environment with wet with the micro climate between clothes, and cotton fiber absorbs water
Big with water retention, sweat, sweat vapour are difficult to excrete rapidly, to produce feeling of oppression and heat；Furthermore because gas permeability declines and is sticked to skin
On, while moisture divergence speed is slow, to cause a kind of clammy sense to human body；Synthetic fibers, by taking terylene as an example, water suction
Property it is small, perspective performance is poor, due to its accumulation of static electricity, when wear, the easy trouble tangled of initiation.Therefore, it is necessary to one kind to be suitble to
The moisture absorbing and sweat releasing agent of public demand makes that the moisture absorbing and sweat releasing performance of clothes or fabric is more preferable, dress is more comfortable.
Polyurethane material has good adhesive property with high intensity, high moisture-inhibiting performance and to a variety of materials, and gathers
Ether-based polyurethane has good anti-hydrolytic performance, therefore it is synthetic route that the present invention, which selects polyether polyurethane, synthesizes one kind
The preparation method of water-fastness polyurethane-type moisture control agent.
Summary of the invention
Reasonable water-fastness poly- ammonia is designed in view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of
The preparation method of ester type moisture control agent.
To achieve the above object, the technical solution adopted by the present invention is that: the water-fastness polyurethane-type moisture absorbable and breathable finishing
The parts by weight of the main synthesis material of agent are as follows: 17~20 parts of polypropylene glycol (3000 molecular weight), polyethylene glycol (1000 molecular weight) 4
~5 parts, 1~2 part of methyl diethanolamine, 4~5 parts of isophorone diisocyanate, 8~9 parts of ethyl alcohol, surplus is water.
The synthetic method of the water-fastness polyurethane-type moisture control agent is as follows:
1, in 500ml glass reaction kettle, polypropylene glycol is added, meanwhile, starting stirring, revolving speed 200rpm, heating；
2, after feeding, material temperature is made to rise to 50 DEG C or more 80 DEG C or less, stops stirring；
3, polyethylene glycol (solid needs heating melting) is added, is warming up to 100 DEG C, sees whether to be fused into liquid, to base
This is at starting stirring, revolving speed 200rpm after liquid；
4, start to vacuumize water removal, 120 DEG C of temperature for removing water, remove water time 2h, remove water pressure -0.099MPa；Water removal terminates
Afterwards, that is, stop vacuum；
5, it is passed through nitrogen concora crush and guarantees to keep pico- positive pressure in kettle, so that temperature of charge is cooled to 100.0 ± 5 DEG C, stop
It is cooling；
6, mixing speed is reduced, revolving speed is adjusted to 100rpm, isoflurane chalcone diisocyanate, methyl diethanolamine is added,
Stir 30min；
7, adjustment mixing speed is started to warm up to 200rpm to 100 ± 5 DEG C；Cool down after reaction 5h；
8,50.0 DEG C are cooled to hereinafter, 8~9 parts of ethyl alcohol (135-155kg) of addition, continues to stir 60min；
9, distilled water is added, adjustment mixing speed to 400rpm continues to stir half an hour after charging；
10, it inspects by random samples, pack discharging, labelled storage.
Water-fastness polyurethane-type moisture control agent method in conjunction with fabric of the present invention is as follows: according to the suction of formulation
Formula combination is arranged, auxiliary agent is weighed, is diluted with water to equivalent concentration, is slowly stirred uniformly, pH value, the pH value requirement of working solution are tested
6-7 is adjusted to 6-7 with glacial acetic acid dropwise addition if pH value is higher；Configured working solution is drenched into stamping roller on a small quantity, fabric infiltrates work
It after making liquid, is laid on roll and rolls redundant work liquid, dry, be formed and test and assess.
After adopting the above structure, the invention has the following beneficial effects: a kind of water-fastness polyurethane-type moisture absorption row of the present invention
Sweat finishing agent is convenient in conjunction with existing fabric, and after finishing agent of the invention, fabric can be avoided existing in the prior art
Problem, moisture absorbing and sweat releasing performance greatly improve, and fabric no longer becomes closely, and stomata no longer blocks, the micro climate between skin and clothes
Heat exchange between external environment exchanges normally with wet, will not generate feeling of oppression and heat, and permeability is good, clothes is not bound to skin
On, electrostatic will not be generated, the comfort level of user is improved；In addition, the present invention has simple process, setting rationally, is fabricated to
This low advantage.
