Description
Technical field
The present invention relates to a kind of regenerated celulose fibre and preparation method thereof, specifically, relate to a kind of jade nice and cool again
Raw cellulose fibre and preparation method thereof, belongs to textile technology field.
Background technology
Along with fast development and the improving constantly of people's living standard of science and technology, people are to the requirement of clothing the most not only
It is only to cover body resisting cold, but pursues safe, comfortable, attractive in appearance and more practical function.During the broiling summer, wear one to feel nice and cool thoroughly
The clothes of gas can not only improve the comfort level of health, moreover it is possible to brings good mood to people, is conducive to work and life.
The most just there is the good name of state of jade in China, containing the abundant mineral useful to human body and micro-in jade
Secondary element, is attached to for a long time on the skin of human body, discharges, and can improve blood microcirculation, enhance metabolism, thus reach
Prevention disease, the effect of allaying tiredness.Proving through mineral medical research, jade can produce the photoelectric effect of high intensity, in processing
During can focusing energy storage, formed magnetic field, can produce when wearing and be of value to the resonance of human body.Existing investigative technique shows, adds
The textile adding jade can allow human body have preferable cooling feeling, particularly during high temperature, and fabric energy relative reduction temperature, allow people feel
Comfortable.
The most more about the research of jade fiber, but all it is confined to synthetic fibers aspect, as Shanghai De Fulun chemical fibre has
The super cool cool feeling health care polyester fiber that limit company prepares with polyester fiber production technology, Jin Hui new fiber materials company limited produces
The refreshing Liz etc. containing jade material, but in terms of regenerated celulose fibre, there are no elaboration.
Patent 200710023666.9 discloses a kind of infinitesimal jade fiber, is by Subnano-class jade granule and spinning
The fiber with preferable cooling feeling is prepared in melt spinning together.Patent 201410354049.7 discloses one and has core-skin knot
The fire-retardant ice of structure is felt well recycled polyester filament fiber, nice and cool master batch that cortex is made up of lamellar jade, titanium dioxide, zinc oxide and again
Raw polyester slice melt spinning obtains, and sandwich layer is cut into slices what melt spinning obtained by fire-retardant master granule and recycled polyester, and this fiber has
There is nice and cool and fire resistance.Patent 201310497670.4 discloses the preparation method of a kind of chinlon 6 cool jade fiber, this fiber
Jade and other beneficial mineral materials are prepared as Subnano-class particle diameter, fuse into spinning processing among chinlon 6 melt and obtain,
Comparing cooling feeling with common Silk shell fabric strong, wearability is strong.
Above technology is all jade to be prepared as powder body carry out blend melt spinning, does not mention and jade is prepared as slurry
Technology with cellulose carries out solution blending spinning, during this has resulted in fibre spinning, is susceptible to particle aggregation, causes
Blocking spinning head, fiber spinnability is poor.
The most existing technical scheme is all interpolation jade material in synthetic fibers；Owing to synthetic fibers itself do not have again
The moisture absorption giving birth to cellulose fibre, the characteristic perspired, the fabric cool feeling therefore prepared is general.
Summary of the invention
For the deficiencies in the prior art, the present invention provides a kind of jade to feel nice and cool regenerated celulose fibre and preparation method thereof,
To realize following goal of the invention:
1, the jade cool fiber cellulose fiber that prepared by the present invention, the performance such as fibre strength highlights；
2, the jade cool fiber cellulose fiber that prepared by the present invention, containing appropriate jade so that fabric prepared by this fiber has
Good nice and cool sensation；
3, during preparing regenerated celulose fibre, spinnability is preferable, and the fibre defect of preparation is less；
4, the jade cool fiber cellulose fiber of preparation, nice and cool sensation is substantially；
5, the present invention is at the jade slurry of preparation, it is possible to not producing reunion in ensureing 12 hours, jade is uniformly distributed in the slurry,
It is difficult to layering, can directly utilize and spin front injecting systems and join in spinning liquid；
6, the regenerated celulose fibre in the present invention is with bamboo pulp as raw material, and the fiber prepared has the nice and cool of bamboo fibre and relaxes
Fit, resist the advantages such as antibacterial；
7, jade slurry is joined in spinning glue by injection before spinning by the present invention, and addition manner is easy, it is easy to PROCESS FOR TREATMENT.
In order to realize foregoing invention purpose, the technical solution used in the present invention is:
A kind of jade is felt nice and cool regenerated celulose fibre, it is characterised in that: containing jade in described regenerated celulose fibre.
The following is and the further of technique scheme is improved:
In described regenerated celulose fibre, jade content is: 3.96-14.68%.
It is 1.51-2.49 cN/dtex that described regenerated celulose fibre does fracture strength；Wet breaking strength is 0.83-1.50
cN/dtex；Dry elongation at break is 14.2-18.9%.
A kind of jade is felt nice and cool the preparation method of regenerated celulose fibre, it is characterised in that: described method includes configuration dispersion
Liquid step；Described configuration dispersion liquid step includes: deionized water is heated to 30-40 DEG C, adds the dispersion of cellulose derivative class
Agent, with sodium hydroxide regulation aqueous solution pH at 8-10, is subsequently adding dodecylbenzene sodium sulfonate.
Described cellulose derivative class dispersant is carboxymethyl cellulose, carboxyethyl cellulose, hydroxyethyl cellulose, crystallite
One or more of cellulose；In described dispersion liquid, the concentration of cellulose derivative class dispersant is 0.5-1.5wt%.
Described method also includes configuring slurry stage；In described slurry, the concentration of jade powder is 10-30%wt.
Described method also includes grinding steps；Described grinding steps includes: added in ball mill by the jade slurry of preparation
It is ground, within every 20 minutes, changes a rotating, after grinding 2-4 hour, use ultrasonic echography 8-15min, supersonic frequency
20KHz。
Described method also includes filtration step；Described filtration step: by particle diameter in the jade slurry after grinding steps more than 2
The jade particle of μm leaches.
Described method also includes spinning glue preparation process；The pulp material that described spinning glue uses is to use bamboo pulp；Institute
State in spinning glue preparation process, slow release forming agent need to be added；Described slow release forming agent is Polyethylene Glycol；Described slow release forming agent
Addition is the 0.1-0.5wt% of cellulose in spinning glue.
Described method also includes co-blended spinning liquid preparation process；Described co-blended spinning liquid preparation process includes: by configuration well
Jade slurry be stirred mixing with the spinning glue of preparation；Described mixing time is 40-60min, and whipping temp is 18-22
