Description
Technical field
The present invention relates to a kind of preparation methods of viscose filament yarn, it is more particularly related to a kind of preparation of cold silk
Method belongs to easy cold adhesive long filament and manufactures.
Background technology
Cold silk is a kind of new product of viscose filament yarn, belongs to ecological fiber, derived from certainly however better than nature.Due to cold silk
Moisture percentage best suits the physiological requirement of human skin, therefore its operation strategies is wide, and cloth, catgut, mask and other products, institute is such as made
Manufactured cloth has smooth nice and cool, ventilative, antistatic, comfortable, health care and other effects, has good market to use foreground.Cold-storage
Agent be it is a kind of by organic or（With）Inorganic compound forms translucent（Or it is opaque）, sticky colloidal mixture, can be low
It is absorbed under temperature and stores a large amount of colds, and a large amount of colds can be released when temperature is higher, the long period keeps itself and surrounding
The low temperature environment of a small range.In surfactant big family, sulfosuccinic acids surfactant is wide with raw material sources, closes
At simple for process, production cost is low, mild to skin, irritation is small, bio-safety is degradable, three-waste free pollution etc. meets safety
The new concept of environmental protection and higher surface-active（Its aqueous solution surface tension is up to 27-35 mN/m）The advantages that and by widely
Applied to coating, synthetic resin, weaving, leather, medicine, mining, agricultural, building materials, plating, accumulator, adhesive and detergent
[1,2] industries such as.
In the prior art, the preparation method of cold silk mainly has rigid requirement to raw material, this causes in prepared by cold silk
To raw material type harshness, raw material is difficult to obtain, and production is caused to bear；Meanwhile the preparation process of cold silk is complicated, is wanted to technological parameter
Ask high；Moreover, the cold silk type that prior art obtains is single, it can not meet the market demand.
Invention content
The present invention single etc. problem of rare, complex process, product category for raw material in the prior art, and provide
A kind of preparation method of cold silk.By in the preparation method of viscose filament yarn, cold-storage material is added, it is simple to reach production method, cold
Silk type is abundant, the high effect of productivity.
A kind of preparation method of cold silk, which is characterized in that include the following steps：
A. prepared by viscose glue stoste
Using natural fiber as raw material, pulp is extracted；Pulp obtains cellulose xanthan after lye and carbon disulfide processing
Acid esters；Cellulose xanthate ester obtains viscose glue stoste after processing in dilute alkaline soln；
B. prepared by easy cold bonding collagen solution
After mixing by static mixer by cold-storage material and above-mentioned viscose glue stoste, easy cold bonding collagen solution, cold-storage are obtained
The flow velocity that agent enters static mixer is more than the flow velocity that viscose glue stoste enters static mixer；
C. spinning pre-treatment
Meanwhile the dispersant for 0.1-0.3% weight ratios being injected in above-mentioned easy cold bonding collagen solution, obtain final spinning
Stoste, subsequently into conveying pipeline；
D. spinning
Above-mentioned spinning solution arrives at spinning-drawing machine by conveying pipeline, then weaving forming carries out the post-processing of this field routine
Method obtains final cold silk.
The cold-storage material by polyvinyl alcohol, water-absorbing resin, sodium sulphate, preservative, water is formulated forms.
The dispersant includes sulfosuccinate.
The lye and dilute alkaline soln are all sodium hydroxide solution, and concentration of sodium hydroxide solution is 10%-20%.
The cold-storage material and the mixing of viscose glue stoste, wherein cold-storage material is 1%-30%, viscose glue stoste is 70%-99%, described to contain
Amount is weight percentage.
The advantageous effects that the present invention is brought：
1. in the present invention, the preparation method of cold silk, cold-storage material and viscose glue stoste by static mixer after mixing,
By conveying pipeline, it is routed directly to spinning board spinning, without being further added by easy cold bonding collagen solution storage tank and filter plant after mixing, greatly
Reduce the waste of viscose glue, cold-storage material when tearing filter in daily production process open, rushing jar and pipeline greatly, while reducing environment dirt
The expense of water harnessing and the pollution of environment.Simultaneously as after viscose glue stoste enters the pipeline of static mixer, it can solidify and cause pipe
Road blocks, and the flow velocity of cold-storage material is more than viscose glue stoste, is introduced into pipeline, avoids the entrance of viscose glue stoste, will not cause plugging, really
Spinning process is protected to be smoothed out；
2. in the present invention, the addition of cold-storage material avoids the rigors to raw material in the preparation method of conventional cold silk,
To keep preparation method simple, production procedure is short；
3. in the present invention, cold-storage material and the mixing of viscose glue stoste, wherein cold-storage material is 1%-30%, viscose glue stoste is 70%-
99%, the configuration of different proportion produces the cold silk of different size and type, and meets the needs of people；
4. in the present invention, for the spinning property of cold silk spinning silk stock solution made of increasing, improve at after silk cold silk it is micro-
Structure is seen, enhances the intensity and toughness of silk, spinning solution injects the dispersant sulfo group of 0.1-0.3% weight ratios before spinning moulding
Succinate.
5 in the present invention, and the post-processing approach of this field routine is carried out in spinning line, and the method has been ripe skill
Art.And change the main production of existing conventional viscose rayon, and using pipeline mixing and injecting method, existing easy cold bonding collagen solution
It prepares, less investment makes to be that this preparation method is simple, and controllability is strong, has further guarantee to spinning line.
