Description
Technical field
The present invention relates to a kind of cool feeling regenerated celulose fibre, particularly a kind of cool feeling regenerated celulose fibre and preparation method thereof, belongs to textile industry Material Field.
Background technology
In recent years, people are except pursuing the fashion appeal of summer clothes, and the requirement of people to the cool and comfortable of underclothes also constantly increases.Therefore, various cool feeling, temperature-regulating fiber are also raw thereupon applying.
So-called cool fiber utilizes occurring in nature speed of absorbing heat slow, and the fast medium of radiating rate adds in the carrier such as terylene, polyamide fibre, and the fabric woven just has the excellent cool feeling produced in the moment of contact skin.The research of current cool fiber is relatively many, and product on the market also emerges in an endless stream, but is mostly to be applied in synthetic fiber field.
Chinese patent 201110295850 discloses a kind of cool fiber and preparation method, this patent is by nano level inorganic filler being added to thermoplastic elastomer (TPE) as in polyamide-based elastomer or polyester elastomer, after abundant mixing, carry out melt spinning and obtain cool fiber.The obtained fiber of this method mostly is synthetic fiber, though give fiber certain cool feeling, does not solve synthetic fiber as the shortcoming of hygroscopicity difference taking product summer.Chinese patent 20071002366 discloses a kind of preparation method of microelement biological jade fiber, and this patent is added in spinning melt by the nano level jade powder containing trace element, makes the fiber with certain cool feeling through spinning process.The fiber that this method obtains still does not solve synthetic fiber inherent defect, just can only make it to be suitable as product use in summer by blending, but blending product can fall low-fiber cool feeling to a certain extent.Chinese patent 201210062635 also discloses a kind of method adopting the mode of fiber post processing to prepare cool fiber, this method utilizes adhesive natural with all kinds of by certain physics chemical action to nano level pearl powder, crystal powder etc., synthetic fiber to be combined, obtained cool fiber.Though this method can obtain skin-friendly good summer cool product, can the durability of gained cool fiber is poor.
Directly can react the specific heat capacity that direct parameter that whether fiber have a cool feeling is fiber, specific heat capacity is when directly reacting fabric contact human body skin, from the number of the heat that human body is taken away, affect fabric to the parameter intuitively of the sensation of people, its definition is the fiber of unit mass, the heat of absorption (or releasing) required for 1 DEG C that temperature raises (or reduction).The specific heat capacity of general fiber is between 1-2 J/ (g DEG C), and specific heat of water appearance is 4.18 J/ (g DEG C), therefore fibre moisture regain rate or moisture content is improved, fiber and moisture composite construction specific heat capacity also can improve thereupon, when the specific heat capacity of fiber reaches corresponding value, fiber and fibre will have cool feeling.
Summary of the invention
Object of the present invention: for the deficiencies in the prior art, exploitation one has hydroscopic fast-drying, there is the regenerated celulose fibre of contact cool feeling, the specific heat capacity of fiber is improved by the regain improving fiber, make fiber and its products have cool feeling, a kind of preparation method with regenerated celulose fibre is provided simultaneously.
For achieving the above object, the present invention will take following technique effect:
A kind of cool feeling regenerated celulose fibre, comprises alpha cellulose, hygroscopic agent, dispersant, adopts blend method, hygroscopic agent and dispersant is added in the rayon spinning stoste containing alpha cellulose and obtain through spinning.
Alpha cellulose be cellulosic material in 20 DEG C of sodium hydroxide solutions being dipped in 17.5% or 18% after 45 minutes undissolved part.
Hygroscopic agent is the one in high hydroscopic resin, calcium chloride, montmorillonite, kaolin.
The average grain diameter of hygroscopic agent is 0.20 ~ 3.00 μm.
Dispersant is calgon, tristerin, stearate one wherein.
Another technical purpose of the present invention puies forward a kind of preparation method of above-mentioned cool feeling regenerated celulose fibre, comprises following technical step:
(1) Making viscose spinning solution;
(2) hygroscopic agent aqueous dispersion system solution is prepared;
(3), after being mixed with the rayon spinning liquid of step 1 by the hygroscopic agent aqueous dispersion system solution of step 2, wet spinning is carried out.
The preparation method of cool feeling regenerated celulose fibre of the present invention, specifically comprise the steps: A, the concrete preparation technology of rayon spinning stoste be: be the Cotton Pulp of 93.5% by the degree of polymerization 500, the fine mass content of first, successively through dipping, squeezing, pulverize, experienced, yellow, dissolving, filtration, the operation such as deaeration make;
The concrete preparing process of B, hygroscopic agent aqueous dispersion system solution is: in reactor, take water, hygroscopic agent, dispersant by formula, fully stirs and can obtain comparatively uniform hygroscopic agent emulsion; Adopt sheet frame filter to filter through double-deck fine cloth, keep pressure at below 0.2Mpa, obtain uniform hygroscopic agent dispersion emulsion;
C, viscose solution mix with hygroscopic agent dispersion emulsion: step B gained hygroscopic agent dispersion emulsion adds in the viscose solution prepared by steps A by adoption rate pump quantitatively, and mixes;
D, wet spinning: step C gained mixed solution is sent into wet spinning operation and carries out spinning, obtain cool feeling regenerated celulose fibre.
Hygroscopic agent accounts for the 5%-15% of the fine quality of first in rayon spinning stoste.
Dispersant accounts for the 1.5%-2.5% of the fine quality of first in rayon spinning stoste.
In hygroscopic agent dispersion soln, each constituent mass proportioning is: hygroscopic agent 10-20 part, dispersant 3-5 part, water 75-87 part.
By technique scheme originally, the beneficial effect acquired by invention is:
One, in the present invention, hygroscopic agent can absorb the moisture accounting for own wt 100%-500%, and adding of hygroscopic agent makes the moisture content of fiber also increase thereupon, thus causes cellulose fibre specific heat capacity to increase, make fiber and as fabric be have moment contact coldness.
Two, adopt blended method to be added to by hygroscopic agent in rayon spinning stoste and not only there is contact coldness through the regenerated celulose fibre that spinning is obtained, also change the advantage of cellulose fibre itself, as hydroscopic fast-drying, good pro-skin performance etc., these are all that synthetic fiber can not have.
Three, after hygroscopic agent moisture absorption can also and cellulose macromolecule on hydroxyl have an effect in the mode of hydrogen bond, hygroscopic agent is made to anchor at fibrous inside securely, hygroscopic agent can be made more even in dispersion dispersion adding of dispersant simultaneously, thus make it also more abundant with mixing of spinning solution, the hygroscopicity of the fiber finally obtained is more evenly thorough, and the durability of contact coldness that therefore this fiber or the fabric that adopts this fiber to make have will significantly better than the fiber with contact coldness adopting the method for post processing obtain or fabric.
