Description
Technical field
The present invention relates to a kind of preparation methods for improving viscose rayon dry and wet intensity, belong to textile fabric processing technology neck
Domain.
Background technique
The features such as viscose rayon is smooth nice and cool, hygroscopicity is high, dyeability is good, antistatic, antiultraviolet due to its, makes to wear
Person's comfort level is high；In addition viscose rayon is the cellulose fibre produced using cotton or other natural fibers as raw material, is environmentally protective
Ecological fiber, derived from day however better than natural, therefore viscose rayon has been widely used in various textile garment fields.But it is viscous
The mechanical performance of glue fiber is poor, and strength is small, and modulus is low, and mutability, elastic recovery rate is poor, the feel especially after being lauched
It hardens variation, dimensional stability is not high, seriously affects the beauty of fabric.
Chinese publication CN105586781A, publication date on May 18th, 2016, invention and created name was a kind of viscous
The process of surface treatment of glue fiber wet strength enhancing, this application discloses a kind of surface treatments of viscose fiber wet strength enhancing
Technique, it is characterised in that fiber is taken up in order of priority and is placed in equipped with surface active solution, wet strong reinforcing agent and chelated surface treatment fluid
Treatment trough in impregnate after by high temperature curing process be made high humidity strength.By the inventive method treated viscose rayon
With lasting high wet strength, wash resistant, and entire technical process is pollution-free, nuisanceless, is conducive to environmental protection and mankind Jian
Health.But this method need to grafting be total in the treatment trough equipped with wet strong reinforcing agent again after surface active solution dipping by fiber
It is poly-, it finally also needs by being handled in the treatment trough equipped with chelated surface treatment fluid, this method operating process is cumbersome, technique is time-consuming
Long and last hot setting processing is easy to influence the performance of fiber.
In conclusion the method that viscose fiber strength improves not only will effectively promote the intensity of fiber, and need to meet
Simple process, operation are easy, and process is controllable, to the theory that environment does not pollute, so, we have proposed this raising viscose glues
The preparation method of fiber dry and wet intensity.
Summary of the invention
There are problems for above-mentioned, and it is an object of the invention to overcome drawbacks described above, it is dry to provide a kind of raising viscose rayon
The preparation method of wet strength is to meet the technical solution of the object of the invention：
A kind of preparation method improving viscose rayon dry and wet intensity, the preparation method is according to the following steps：
Multi-group crosslink agent and organic solvent be respectively by A by mass fraction：
Multi-group crosslink agent 2%~4%
Atent solvent 96%~98%
It is sealed after mixing, is placed in magnetic stirrer and stirs evenly, be configured to crosslink finishing liquid, wherein whipping temp
It is 15~30 DEG C, mixing time is 3~5 minutes, and the revolving speed of blender is 100~500 revs/min.
Viscose rayon is placed drying in baking oven by B, and controlling its regain is 1~20%, is taken out and is sealed after the completion of drying
It is spare.
Pretreated viscose rayon is pressed 1 by C:5 bath raio is impregnated in above-mentioned crosslink finishing liquid, then to viscose glue fibre
Dimension heat treatment carries out cross-linking reaction, wherein heat treatment temperature is 80~120 DEG C, and heating treatment time is 1~2 hour.
Viscose rayon after D taking-up cross-linking reaction bakes 5~10 minutes at 80 DEG C to get powerful in 3.0cN/ to doing
Dtex, the viscose rayon of wet powerful high level cadre's wet strength in 2.0cN/dtex.
The multi-group crosslink agent is titanium tetraisopropylate or titanium tetrachloride or butyl silicate or trimethyl aluminium or two
One of zinc ethyl etc..
The atent solvent is one of ethyl alcohol or acetone etc..
Due to using above technical scheme, advantageous effects of the present invention are：
1 the present invention utilize multi-group crosslink agent activity, in anhydrous environment with the hydroxyl on viscose rayon surface into
Row hydrolysis, reaction product are attached in fiber surface and hole, make viscose rayon internal void by reaction product filling and
Bonding crosslinking, to achieve the purpose that improve viscose rayon strength.Multi-group crosslink agent's hydrolysis occurs in fiber sheath,
Do not change fibrous inner structure and property, the strength of fiber will not be damaged, organic solvent is not reacted with fiber, to fiber without
It influences.And multi-group crosslink agent and the available property of organic solvent are more, source is relatively broad.
The not only intensity with higher of high level cadre's wet strength viscose rayon obtained by 2 present invention, gained viscose fiber strength
It is high by 40% or more compared with viscose fiber strength before handling；And the shortcomings that it is low effectively to improve former viscose rayon modulus, easy deformation,
With good elasticity, hygroscopicity, stainability, corrosion resistance etc., it is widely used.
A kind of 3 preparation methods for improving viscose rayon dry and wet intensity of the present invention, can be directly fine by traditional viscose glue
Dimension is handled；Multi-group crosslink agent's dosage is less, and organic solvent price is more cheap, and raw material environmental pollution is small, technique
Process is few, and operating process facilitates easily-controllable, it is easy to accomplish industrialized production.
Specific embodiment
Combined with specific embodiments below, present invention is further described in detail.
A kind of preparation method improving viscose rayon dry and wet intensity, the preparation method is according to the following steps：
Multi-group crosslink agent and organic solvent be respectively by A by mass fraction：
Multi-group crosslink agent 2%~4%
Atent solvent 96%~98%
It is sealed after mixing, is placed in magnetic stirrer and stirs evenly, be configured to crosslink finishing liquid, wherein whipping temp
It is 15~30 DEG C, mixing time is 3~5 minutes, and the revolving speed of blender is 100~500 revs/min.
The multi-group crosslink agent is titanium tetraisopropylate or titanium tetrachloride or butyl silicate or trimethyl aluminium or two
One of zinc ethyl etc..
The atent solvent is one of ethyl alcohol or acetone etc..
Viscose rayon is placed drying in baking oven by B, and controlling its regain is 1~20%, is taken out and is sealed after the completion of drying
It is spare.
Pretreated viscose rayon is pressed 1 by C:5 bath raio is impregnated in above-mentioned crosslink finishing liquid, then to viscose glue fibre
The hydroxyl on dimension heat treatment, multi-group crosslink agent and viscose rayon surface carries out cross-linking reaction, generates metal oxide grain
Son has filled up the gap between the weak section and fiber of fibrous inside, thus achieve the purpose that enhance viscose rayon strength,
In, heat treatment temperature is 80~120 DEG C, and heating treatment time is 0.5~2 hour.
