Description
Technical field
The invention belongs to chemical fiber field, more particularly, to a kind of noctilucence viscose rayon.
Background technology
Noctilucence textile can offer convenience for dark surrounds work, life.The textile of noctilucence is put on such as child,
Traffic accident can be reduced；Traffic police or road surface street cleaner wear noctilucence work clothes, and passing vehicle can be allowed easily to recognize, improve
The security of work.The preparation method of noctilucence textile has two kinds.One kind is to carry out coating to textile, using the work of adhesive
With the surface that luminescent powder is adhered to textile, though prepared textile has preferable noctilucence performance, fastness is poor, easily
Come off by rubbing action, usage cycles are shorter；Another kind is that noctilucent powder and spinning solution are blended and spinning, the fibre of gained
Though fiber products can improve luminescent powder fastness in the fibre, influenceed by fiber, noctilucence intensity is relatively low, if improving noctilucence
Powder ratio influences whether the spinning property of spinning solution to improve noctilucence performance, then.Institute is blended with spinning solution using luminescent powder at present
Obtained fiber is generally synthetic fibers, the less staple fibre for being applied to more have sense comfortable and easy to wear, especially in viscose rayon.
From the foregoing, it will be observed that a kind of noctilucence performance with preferable fastness, higher of exploitation and the noctilucence of good sense comfortable and easy to wear
Viscose rayon product undoubtedly has important practical significance.
The content of the invention
Currently there is the noctilucence viscose rayon of preferable fastness, noctilucence performance higher and good sense comfortable and easy to wear to overcome
The problem of underexploitation, the present invention provides a kind of noctilucence viscose rayon.
The present invention is realized by following technology：
A kind of noctilucence viscose rayon, the noctilucence viscose rayon is skin-core structure, and core is adhesive-layer, and skin is noctilucence layer, the noctilucence
Viscose rayon preparation process is as follows：
1) preparation of rayon spinning stoste：Take impregnated timber, squeezing, crushing, experienced, yellow, dissolving, maturation, deaeration filtering
Technique prepares rayon spinning stoste (1)；
2) spinning：Rayon spinning stoste (1) is extruded by spinneret (2), into spinning shaft (5), carries the heat of noctilucent powder
Air enters spinning shaft (5) by air intake vent (4), porous plate (3), is blown out by air outlet (6), during hot-air flowing,
Noctilucent powder adheres to rayon spinning stoste (1) surface；Then, surface adhesion has noctilucent powder to consolidate in being introduced into coagulating bath (7)
Chemical conversion type, obtains final product noctilucence rayon fiber；
3) hot rolling：By noctilucence rayon fiber derived from coagulating bath is by godet (8) introducing hot roll (9) and carries out hot rolling；
4) cleaning and collection：The noctilucence rayon fiber of hot rolling is through clear water bath (10) washing, drying roller A (11), steam stretching groove
(12), drying roller B (13), collection obtains noctilucence viscose rayon (14).
The fiber with noctilucent function is prepared using noctilucent powder and spinning solution blending, noctilucent powder is uniform in spinning solution
Dispersion, top layer distribution is less, and luminous effect often depends on the noctilucent powder of fiber sheath, in order to improve luminous effect
Then need the concentration of the powder light powder in raising mixed liquor.The adding method of traditional noctilucent powder is different from, the present invention is utilized
The rolling action of hot-air, noctilucent powder is adhered to the surface of rayon spinning liquid, under with the blending of top layer rayon spinning liquid,
Noctilucent powder is evenly distributed on the top layer of rayon spinning liquid, be core-skin knot through the solidification gained noctilucence viscose rayon of coagulating bath
Structure, sandwich layer is consistent with common viscose fiber basis, and cortex is then noctilucence layer.It is blended with traditional noctilucent powder and spinning solution and is spun
The prepared viscose material of silk is compared, and the present invention can be used less noctilucent powder, and play preferable luminous effect.Through invention
People studies display repeatedly, and the mechanical performance of the noctilucence viscose rayon obtained by the present invention is similar to common viscose fiber, luminescent powder
End is more uniform in viscose rayon surface distributed, and its thickness depends primarily on the concentration and air flux of noctilucent powder in hot-air, compared with
Noctilucent powder concentration high, air flux then contribute to obtain thicker noctilucence layer, the viscose rayon of more preferable luminous effect.
In order to improve attachment and luminous effect of the noctilucent powder on viscose rayon surface, inventor increases in the technique of spinning
Add hot rolling technology, under the action of heat, the noctilucent powder on viscose glue top layer is easier to be exposed, also cause noctilucent powder more
