Embodiment 1

[0028] Mix 9 parts of crushed natural cellulose, 1 part of opal light shale superfine powder and 100 parts of [BMIM]Cl (1-butyl-3-methylimidazolium hydrochloride) ionic liquid, at 45 ° C After stirring for 24 hours, a spinning solution was obtained.

[0029] After the spinning solution is filtered and defoamed, it enters a coagulation bath containing 5% ionic liquid through a porous spinneret, and the temperature of the coagulation bath is 25°C. After 10% stretching, then through programs such as washing, bleaching, oiling, drying, etc., the spinning speed is 5 m / min to obtain fibers with a strength of 2.5 cN / dtex.

Embodiment 2

[0031] Mix 10 parts of crushed bacterial cellulose, 0.1 part of inorganic mineral powder (opal light shale: zeolite powder: brucite powder: sepiolite powder: 9.5:0.1:0.2:0.2) and 90 parts of [BMIM]Cl ionic liquid uniform, and stirred at 100°C for 120 hours to obtain a spinning solution.

[0032] After the spinning solution is filtered and defoamed, it enters the water coagulation bath through the porous spinneret, and the temperature of the coagulation bath is 15°C. After 3% stretching, then through programs such as washing, bleaching, oiling and drying, the spinning speed is 20 m / min to obtain a fiber with a strength of 3.3 cN / dtex.

Embodiment 3

[0034] Mix 1 part of crushed cotton, 0.2 part of inorganic mineral powder (opal light shale: zeolite powder: brucite powder: sepiolite powder at a ratio of 6:2:1:1) and 3 parts of [AMIM]Cl(1-allyl Base-3-methylimidazolium hydrochloride) ionic liquid was mixed evenly, and stirred at 60° C. for 80 hours to obtain a spinning solution.

[0035] After the spinning solution is filtered and defoamed, it enters a coagulation bath containing 25% ionic liquid through a porous spinneret, and the temperature of the coagulation bath is 55°C. After 8% plasticizing and stretching, then through procedures such as washing, bleaching, oiling, and drying, the spinning speed is 30 m / min, and the fiber with a strength of 2.1 cN / dtex is obtained.

Abstract

The invention relates to preparation and application of a cellulose / inorganic breeze compound fiber that releases negative ions. The preparation: (1) ground cellulose, inorganic breeze, an assistant are evenly mixed with ionic liquid, dissolved and defoamed at 35-160 DEG C for 1-120 hours, thus forming even and stable spinning solution with the total solid content of 3-30 percent, wherein, the mass mixture ratio of the inorganic breeze is 0.01-20 percent and the added mass of the assistant is 0-10 percent; (2) the mixture is carried out by spinning and curing of solidifying bath after being filtered and defoamed; (3) the cellulose / inorganic breeze compound fiber is obtained by stretching, water washing, blanching and the procedures of oiling and drying. The compound fiber not only has the function of releasing negative ions, but also has the functions of producing far-infrared radiation, generating biocurrent and inhibiting bacteria, etc., thus being applicable to the fields of costume, decoration and medical textile product. The preparation and application of the cellulose / inorganic breeze compound fiber uses the ionic liquid, which has high production efficiency and easy recycle and meets the requirement of green production and the obtained compound fiber has good mechanical strength and mechanical property; fabrics made from the compound fiber can release negative ions and has the effect of antibacterium and rot resistance.

Description

technical field [0001] The invention belongs to the field of negative ion fibers, in particular to the preparation and application of a cellulose / inorganic mineral powder composite fiber releasing negative ions. Background technique [0002] Among all substances in nature, cellulose not only has a large reserve, but also has a huge recovery capacity. Only very little cellulose is currently made into fibers. The amount of cellulose used to make fibers and films is less than 4% of the world's industrially produced cellulose. With the continuous deepening of human understanding of nature and the increasing shortage of resources such as oil, coal, and natural gas, the utilization of cellulose will gradually expand. Since cellulose fiber can be converted into water vapor and carbon dioxide by biodegradation or safe combustion, the cellulose fiber causes less environmental damage caused by waste. Therefore, the development of cellulose fibers is very necessary. Among them, the...
