Abstract

The present invention relates to a medical stone function fiber and a preparation method thereof, which belongs to the field of textiles. Medical stone miro-powder accounting for 0.001 to 30 wt% of a fiber is prepared into a medical stone refined solution by a special processing technology, and then the medical stone refined solution is added to viscose during the preparation process of viscose fibers to prepare the medical stone function fiber by spinning with an approximate conventional technology. The fiber contains a plurality of trace elements and rare-earth elements of medical stone, and thus, the fabrics made of the fiber have favorable physiotherapy and health care functions on human bodies.

Description

Functional Chinese medical stone fibres and manufacture method thereof

The present invention relates to a kind of functional fibre, especially functional Chinese medical stone fibres and manufacture method thereof belong to field of textiles.

Viscose fiber fabric has advantages such as good hygroscopicity, dyeability and low price because of it, be the main raw material of textile industry always, and its fabric extremely consumers in general is welcome.Along with the development of textile industry and the raising of people's living standard, people more and more pay attention to the health of human body self, a kind of " infrared multifunctional fiber and manufacture method " (publication number CN1123849A) disclosed so have the fabric of functions such as various health cares, the physiotherapy Chinese invention patent that quietly sells well on market, this method is to add some to have functional materials such as special fuel factor, magnetic effect and infra-red radiation in fibre-forming polymer, and the fabric that fiber process is become has the good health care effect.But do not find to contain the functional fibre of medical stone as yet.

The purpose of this invention is to provide a kind of functional Chinese medical stone fibres and manufacture method thereof with unique biological effect and magical pharmacological effect, the fabric that is made into functional Chinese medical stone fibres can play better health-care physiotherapeutic effect to wearer's human body, thereby further adapts to the demand in market.

Medical stone is a kind of natural medicine ore, because of wherein containing multiple and closely bound up trace element and the rare earth element of health, and has the pharmacological effect of unique biological effect and mystery.Since the sixties in this century, health drink that medical stone makes, health care device etc. appear utilizing in beginning successively.The present invention changes people drew trace element and rare earth element in the past from mouth convention, various trace elements in the high-quality medical stone and rare earth element after handling, special process are joined in the viscose glue, through firm being adsorbed on the cellulose macromolecule after the spinning, this fiber being become a kind ofly can produce the new type functional textile raw material of unique biological effect and magical pharmacological action human body.

The object of the present invention is achieved like this: this functional Chinese medical stone fibres is in the viscose manufacture process, makes after the refined liquid of interpolation medical stone micro mist, is characterized in that medical stone micro mist weight accounts for the 0.001-30% of fibre weight.

The manufacture method of this functional Chinese medical stone fibres is as follows:

1, the processing of medical stone micro mist

The medical stone raw material through washing, meal, dedusting, removal of impurities, is crushed to granularity 300-500 purpose medical stone micro mist with pulverizer machinery again;

2, the medical stone micro mist is refining

The medical stone micro mist dropped in alkali lye that concentration is the 5-160 grams per liter or the water soaked 24-56 hour, after mechanical agitation, use wherein harmful element such as Hg, Pb of chemical fibre material, micro porous filtration material or the filtering of sepiolite adsorption technology again, the refining liquid of medical stone;

3, the manufacturing of functional Chinese medical stone fibres viscose glue

In the yellow end of a period of viscose glue or course of dissolution the refining liquid of 2 gained medical stones is evenly added in the viscose glue, after 2-5 hour abundant mixing and grinding, making viscosity is the 30-60 functional Chinese medical stone fibres viscose glue with medical stone function of second;

4, the spinning of functional Chinese medical stone fibres

The functional Chinese medical stone fibres viscose glue is filtered the back to be increased 1-3 layer poplin cloth filter cloth and filters through conventional three roads, again behind conventional spinning acid bath, with spinning speed 40-70 rice/minute (than the low 10-20 rice of normal spinning speed/minute) carry out spinning, get functional Chinese medical stone fibres.

The mensuration of viscose riscosity adopts the general normal beam technique of the industry, and its principle is to utilize the steel ball of certain mass, and the speed that descends in viscosity tube is measured its viscosity, and institute's elapsed time is directly proportional with viscosity, so viscose riscosity shows with the time stopwatch.Concrete assay method is: behind the viscose glue sample thermometric that will just fetch, pour drying into and in the clean viscosity tube, the liquid level of viscose glue is flat with the horizontal saliva of test tube mouth, concave and convex phenomenon can not be arranged, and vertically put into rack for test tube.Steel ball is put into test tube mouth center, start stopwatch simultaneously, observe steel ball and arrive pipe during the end, steel ball decline required time number second is write down in stopwatch immediately.Add or deduct temperature correction value, promptly get viscose riscosity.

Below in conjunction with following embodiment the present invention is further described, scope of the present invention is not subjected to the restriction of present embodiment.

The inventor manufactures experimently medical stone function viscose staple fibre:
