It is 185 DEG C that the temperature of cutting is scalded in 4.10 fronts, speed 12m/min, cuts twice along hair, each the scalding of inverse hair;
4.11 back sides scald that to cut temperature be 185 DEG C, and speed 12m/min, inverse hair scalds cuts twice.
As preferably, the specification of described spontaneous heating fiber filament is 150D/144F, and the specification of described polyester FDY is 150D/36F.
The health of people is all the time all in breathing, and no matter be dry environment or moistening environment, human body all can give out slight moisture, and this just becomes the breathing of skin.The moisture that spontaneous heating fiber can absorb human body skin breathing is converted to heat energy by chemical reaction, thus realizes the function of heating.The warming approach that traditional insulation material adopts mainly contains: reduce heat transfer, reduce thermal convection current, improve thermal-radiating reflection and blocking capability, and spontaneous heating fiber is the characteristic relying on self, utilizing extraneous energy and being changed makes it initiatively heat, to reach more efficiently warm, health care effect.Its concrete principle is, spontaneous heating fiber absorbs the moisture that human body distributes, and when moisture cooling post liquefaction, the heat distributed is absorbed by fiber, thus improves temperature.And containing a large amount of miniature air bags in spontaneous heating fiber, while alleviating fibre weight, hot-air can be prevented to run off, make fiber mid portion contain static air, produce good effect of heat insulation.On above basis, spontaneous heating fiber fluffy degree, good hand touch, have elasticity of well relaxing, gently can wrap up health, not fetter sense.Good stability of the dimension, is never out of shape.
As preferably, the preparation method of described spontaneous heating fiber filament is as follows: after blended to polyester granules, lignocellulosic, heat accumulation composite particles and insulation particle, carry out spinning by melt spinning machine, obtained spontaneous heating fiber filament; Wherein said lignocellulosic accounts for the 20-30wt% of overall content, and described heat accumulation composite particles accounts for the 2-4wt% of overall content, and described insulation particle accounts for the 2-4wt% of overall content.
Lignocellulosic has good absorbent function and heat generation, can the moisture of absorbing bodily and sweat.Insulation particle has the effect preventing fibrous inside heat losses, and heat accumulation composite particles can the heat storage capacity of fortifying fibre, prevents external environment condition from being siphoned away by the heat of human body.
As preferably, the preparation method of described insulation particle is as follows: be that to be placed in concentration be that the hydrochloric acid solution of 5-10wt% floods 2-3h for the sepiolite powder of 400-600nm by particle diameter, wherein solid-to-liquid ratio is 1:(5-10); After taking out, cleaning is to neutral obtained insulation particle; The preparation method of described heat accumulation composite particles is as follows: above-mentioned obtained insulation particle is mixed obtained suspension with water, then cetyl ammonium bromide is added in described suspension and add thermal agitation and carry out organically-modified, wherein temperature is 50-60 DEG C, time is 60-80min, and described insulation particle, water and cetyl ammonium bromide mass ratio are 100:(350-450): (10-30); Then organically-modified sepiolite is obtained after taking out drying; Described organically-modified sepiolite is mixed with ethanol and obtains dispersion liquid, stearic acid is added in described dispersion liquid and progressively adds thermal agitation, wherein said organically-modified sepiolite, ethanol and stearic mass ratio are 100:(250-350): (30-40), programming rate is 20 DEG C/h, maximum temperature is 85-90 DEG C, until after ethanol evaporates completely, obtained heat accumulation composite particles after product being carried out drying.
Using sepiolite as insulation particle, because it has the specific area of super large and unique pore passage structure, excellent adsorption, it can be used as fibrous composite, after spinning, make fiber have miniature air bag, these miniature air bags can not only the hygroscopicity of fortifying fibre and the absorbent capacity of increased fiber, also serves fixed air thus heat insulation effect, air themperature in miniature air bag cannot run off after raising, thus temperature is not easily reduced.After sepiolite is carried out acidification, the volume of its specific area and internal gutter can be strengthened, thus its absorption property and heat-proof quality are significantly increased.
Due to the excellent adsorption of sepiolite, therefore, it is possible to serve as carrier, when sepiolite is as heat accumulation composite particles, be exactly as carrier, stearic acid for having good thermal storage performance, by sepiolite after organically-modified, increase it to stearic compatibility, thus increase stearic load capacity, sepiolite, as stearic carrier, has good stability.
As preferably, described spontaneous heating fiber filament before weaving also through pretreatment, concrete grammar is as follows: spontaneous heating fiber filament, beta-schardinger dextrin-are successively added to pH and carry out in the aqueous hydrochloric acid solution of 4-6 adding thermal agitation, and wherein temperature is 40-60 DEG C, and the time is 2-4h; Then in reactant liquor, add sodium cyanoborohydride continue reaction 24-48h, after finally reactant liquor pH being adjusted to neutrality, spontaneous heating fiber filament taken out and clean; The mass ratio of wherein said spontaneous heating fiber filament, beta-schardinger dextrin-, aqueous hydrochloric acid solution and sodium cyanoborohydride is 1:(1-2): (40-60): (0.5-1).
By the surface of grafted by beta cyclodextrin to spontaneous heating fiber filament, beta-schardinger dextrin-has numerous cyberspaces after fiber surface film forming, and these cyberspaces form the miniature air bag of another kind of form, and strong to the absorbability of moisture, sweat; Beta-schardinger dextrin-also can improve the hot strength of fiber after fiber surface film forming on the other hand.
Be compared with the prior art, the invention has the beneficial effects as follows: the spontaneous heating fiber good hygroscopicity adopted in the present invention, spontaneous heating is remarkably productive, and the inventive method, for the performance of spontaneous heating fiber filament uniqueness, develops Rachael blanket and by its industrialization.In textile process process, according to the feature of spontaneous heating fiber, design textile tissue, determine suitable technique, and optimize with production practices by experiment and determine suitable technological process and processing technology, solve all kinds of technical problems occurred in process of production, successfully have developed the excellent novel Rachael blanket with spontaneous heating function.The functional consumers in general just of this woollen blanket woollen blanket need, and its development prospect is more wide.
