Q
What is unique about ASPENOL?
A
ASPENOL is based on modified maize starch and is formulated for spun sizing with less then an 0.5% organic polymers. The products is polyvinyl alcohol free. The products does not require other additives like binder. Softener etc. in most sizing applications.
Q
What is the test procedure before plant trails?

A

Cook ASPENOL at 10% concentration in lab and check the following properties on the polyester sheet (1)Wetting of film (2)Abrasion resistance adhesion
Q
What is the difference between ASPENOL and other components single shot products?

A

ASPENOL has excellent biodegradability and bioeliminatibility. This is due to absence of polyvinyl alcohol or acrylic or polyester resins present in the formulation COD and BOD contributed by ASPENOL would be completely treated in 4/5 days in waster water plant. Polyvinyl alcohol and other polymers, which blends needs 30 days to get eliminated from waste water stream.
Q
Can ASPENOL alone be used for coarse count medium count and finer count?

A

It is recommended that for coarse count. ASPENOL can be used only for very dense construction and high speed weaving, in all other solutions, for coarse count, one can mix ASPENOL with modified and unmodified starches for the best techno-commercial performance.
 
For medium and fine count, one should use ASPENOL by itself particularly for heavy construction of fabrics and loom speeds above 350 rpm. The percentage add on can be adjusted as per the yarn quality, hairiness density of construction & speed of looms. The range could be from 10% to 20%

Q

What is the effect of change of climate and over drying on ASPENOL?
Top

A

ASPENOL has very strong adhesion is cotton as well as polyester. Under dehydrated condition, the film does not delaminate on 100% polyester sheet. 30 minutes blending at 150 c, the adhesion of 100% mylar (polyester) is maintained.

Q

Are there any special procedures for cooking ASPENOL?
ASPENOL is formulated for working like a normal starch in sizing section. Normal, departmental procedure for cooking and dispersing should be followed for ASPENOL.

Q

What is the advantage of handling ASPENOL compared to other starches?

A

Generally, starch based products have powdery character and generates lot of dust in the cooking section. This leads to poor housekeeping, ASPENOL is a fully bonded starch powder and does not generate any dust thus, more comfortable for the operator to prepare size solution as well as allows to improve the housekeeping.

Q

What is the uniqueness of ASPENOL?

A

ASPENOL is the first formulation in the world, which allows a polyvinyl alcohol free recipe based on neutral product to perform equivalent to high polyvinyl alcohol containing recipes. This has never been possible before particularly, for high speed looms for dense sorts, one needs excellent adhesion flexible and consistency.

Q

Are there any grades of ASPENOL available on Tapioca?
Top

A

SUNDOPLUS TT is tapioca version of ASPENOL

Q

What are the difference between ASPENOL & SUNDOPLUS TT?

A

Generally ASPENOL based on matee starch would be able to show 5-10% improved strength compared to SUNDOPLAST TT, whereas SUNDOPLUS TT would have a netro-gradation temperature of almost 10-15 c lower than ASPENOL, which allows improved workability of on the sizing machine, sundoplast TT also is easier to dense compared to ASPENOL ( recommended for Terry Tower)

Q

What is the performance of ASPENOL in terms of gain in strength and loss in elongation?

A

It has been observed that ASPENOL as a formulation allows the sizer to archive higher t has gain in strength compared to generally sizing composition which maintains the lower loss in elongation against consistent formulation. This is most important technical parameter for improved weavebility of the yarn along with excellent smoothness.

Q

Can you tell us about dropping on the sizing machines and on the looms?

A

What sized with ASPENOL, the dropping on the sizing machines is minimum of negligible, same is to on the weaving looms, this reduces the pollution in the sizing section and fluff generation in the weaving section.
Q Is the viscosity of ASPENOL stable after cooking?

A

It has been found that solution can withstand viscosity +- 2-3 seconds over 3-6 hours of storage and working of the sizing solution. This allows weaver to maintain consistence add on warps produced.

Q

Do we need to add any blinder or waxes to ASPENOL if we need to improve the binding and lubricity?

A

Yes, one can add products like polyester resin solution like ASPE-3000 ACP polye or even polyvinyl alcohol from 2% to 10% level. 2 to 5% based on vegetable tallow or paraffin wax can also added to improve the lubricity. Such additive recommendations are done only when we deal with 100% spun polyester or very the counts like 80’s count or 100’s count.
