The AATCC TM82 standard, test procedures, is applicable to bleached, unfinished cotton fabric. The fluidity of a dispersion of bleached cellulose fibers in cupriethylene diamine solvent is a precise measure of the degradation of cellulose resulting from the action of acids, alkalis, oxidizing or reducing agents.
Therefore, it is useful in determining the exactness of the bleaching treatment to which the fabric is subjected and the effect of chemical treatments on the tensile strength of the fabric. (The viscosity of the dispersions in cuprammonium hydroxide was subtracted from this test method).
Acid, alkali, oxidizing or reducing agents, etc. The chain length of the cellulose molecules decreases when treated with The severity of the process determines the degree of cellulose chain shortening and the fluidity or ease of flow of a dispersion. cellulose in solvents.
The fluidity of a cellulose solution is a measure of the ease of flow or movement of a solution and therefore an indicator of the molecular weight of the cellulose. Rhe, unit of fluidity; stands for the reciprocal of the unit of viscosity (stance).
These security measures are for informational purposes only. Precautions are helpful to testing procedures and are not intended to be inclusive. It is the user's responsibility to use safe and appropriate techniques for handling materials in this test method. Manufacturers should always be consulted for specific details such as material safety data sheets and recommendations from other manufacturers. All OSHA standards and guidelines should also be consulted and followed.
Good laboratory practices must be followed, Wear safety glasses in all laboratory areas.
All chemicals should be handled with care. Use chemical goggles or a face shield, waterproof gloves and a waterproof apron when dispensing and mixing. CAUTION: Always add acid to the water.
An eyewash/safety shower should be available nearby and a self-contained breathing apparatus should be available for use in an emergency.
