4) Acetate Yarn
Introduction
1) What is Textile grade cellulose diacetate(DACT)?
Textile grade cellulose diacetate is DCA applied to filament and tow, with combined acetic acid 55%.
The Product brand of DACP
There are totally two kinds of DACT, Namely “NC0” and ”LVI”. NC0 is used to fliament and LVI is used to tow.
The appearance of DACT is whilte flake.Now, the raw material of DACT is purchased from abroad well-organized forest company.
The stable supply of pulp permits the stable properties of DACT.
The process of Textile production
DACP is dissolved in an acetone and water solution to form a concentrated solution(this viscous solution is referred to as dope).
The dope solution is filtered to remove the slightest impurities and extruded through microscopic holes in metal spinnerets.
The number of orifices in a spinneret will vary based on the desired yarn denier.
In this dry spinning process a thread line passes through heated cabinets called metiers to remove acetone.
Then filament or tow is formed after the solvent evaporated.
Attributes of DAC Tow
1.Selective removal of toxic substance in tobacco product, such as tar, phenols.Nitrosamines, quinolines and
other undeired smoke components Without influence on the original taste of cigarette.
2.Natural origin, Environmentally friendly
3.Easy to handle & process
4.Compostable or incinerated
5.Non toxic, tasteless and odorless
6.Easily bonded with additives
7.Construction designable
Attributes of DAC filament
1.Soft with silk-like hand
2.Good drape
3.Comfortable to wear
4.Absorb moisture
5.No static cling
6.Easily to be dyed to bright clear colors at low temperature
7.Versatile, blending easily with other fibers ,such as rayon, silk, nylon, cotton, ployester,etc
8.Nature origin, Environmentally friendly
9.Compostable or incinerated
2)What is Plastic Grade Cellulose Diacetate(DACP)?
Plastic grade cellulose diacetate is DCA applied to glass frame, hand tools, magic tape,
lacquer and other human contacted articles, with combined acetic acid 55%.
The Product brand of DACP
There are totally 5 kinds of DACP, Namely “PC/FG” , ”CS”, “LS/CF”,"LS/EC", “RTW”. The quality of
products can meet different level and current applications of market.
Now, the raw material of DACP is purchased from abroad well-organized forest company.
The stable supply of pulp permits the stable properties of DACP.
The appearance of DACP is white powder, and around 250mm particle size. It is with excellent flow ability and plasticity.
Additionally, the high molecular weight allow the products the pefect performance both in extrusion and laminate process.
The process of plastic articles
1.Primary process
Basically, there 3 kinds of processing method for DACP. The process is chosen based on the final application and form
of the article. But commonly, cellulose acetate needs plasticization prior to the processing, The plasticizers are normally
liquids with high boiling points and low vapor pressure and characterized , in any case, by high affinity with cellulose acetate.
By varying the characteristics of the cellulose acetate, choosing the typology and quantity of plasticizers, adding colorants,
UV stabilizers, inhibitors, metallic dust, optic agent, brightening agents etc, the plastic that results can vary enormously and
the creative possibilities are practically unlimited. With all additives mixed uniformly and giving enough time to plasticize, the
powder is then going to next steps.
Primary process
Typical compounding process
2. Secondary process
Cellulose acetate are easily molded, extruded, or fabricated. It accept various types of secondary processing, including cutting, polishing,
punching, painting, stamping etc.
Attributes of plastic articles
1.Touch/visual appeal
2.Hypoallergenic
3.Sound and feel like wood
4.Excellent balance of toughness, hardness, strength
5.Environmentally friendly
6.Surface gloss
7.Color fastness and brightness
8.Transparency
9.Ease of coloration
10.High quality antifog properties
11.Easily molded, extruded and fabricated
12.Resistant to attack
13.Easily bonded with heat, pressure and plasticizer
14.Resistant to chemicals
15.Resistant to heat
3)What is Plastic Grade Cellulose Triacetate(TACP)?
Plastic grade cellulose triacetate is TAC applied to protective or compensation film of polarizer, with combined acetic acid above 59%.
The Product brand of TACP
Since the post process of TACP are very special and differentially, Push Acetati produce TACP according to the requirement of polydispersity,
degree of substitution and its distribution, etc from different customer. Our all TACP brand are fully customized.
Usually, The appearance of TACP is semi-transparent flake. The raw material of current TACP is cottom linter and purchased from the best cotton
linter producer. Based on this, our
TACP has excellent purities, optical properties, and casting property.
The process of TAC film
After TACP is completely dissolved in a mixed solvent mainly consisting of dichloromethane, the impurities in the dope will be removed with a precise
filter cloth. Then, the transparent dope will be casted on a metal band. And of course, the solvent will be recovered during processing.
Attributes of TAC film
1.Transparency and Optical isotropic
2.Flatness and Surface smoothness
3.Sufficient mechanical(tensile strength, elastic modulus, tear strength)
4.Anti-curl property
5.Dimensional stability against temperature and humidity variations
6.Chemical stability
7.Nonflammable
8.Breathability
