Used in the manufacture of polyvinyl acetal, petrol pipeline and Vigny Lun synthetic fiber, fabric finishing agent, emulsifier, paper coating, adhesive etc..
A water-soluble polyvinyl alcohol fiber and its preparation method, its characteristic is the degree of polymerization and alcoholysis degree of 75-99mo1% 500 ~ 2000 polyvinyl alcohol 100, two dimethyl sulfoxide / water =90 ~ 70, 10 ~ 30 and 200 ~ 400 copies of a mixed solvent, adding stainless steel dissolving kettle, under stirring at temperature 80-120 C, pressure -0.01 ~ -0.08MPa, dissolved in 3 to 4 hours, with the spinning solution, after filtration, deaeration, dry wet spinning and post treatment, obtain water-soluble polyvinyl alcohol fiber, the fiber water soluble temperature 10 to 90 DEG C, the strength is not less than 3.5cN/dtex, the single fiber diameter of 1.5 ~ 10dtex, elongation of 15 ~ 30% the filament, processed into the top, and wool, hemp, cotton sliver and chemical fiber made of high count yarn or hollow yarn, or cut into short fiber nonwoven fabric, embroidery cloth and paper making multiple use.
It has the following properties:
Soluble PVA soluble in water, the higher the temperature the greater the solubility, but almost insoluble in organic solvents. The solubility of PVA manufacturer with the degree of polymerization and alcoholysis degree and change. PVA dissolved fast partial alcoholysis and degree of polymerization, and complete alcoholysis and high degree of polymerization of PVA slow dissolution. The general rules and the influence on the solubility of PVA is greater than the degree of polymerization and alcoholysis degree. PVA dissolution process is carried out in stages, namely: affinity wetting a swelling infinite swelling of a solution.
The film forming PVA easy film, mechanical properties of the film is excellent, the tensile strength of the film and the enhancement degree of polymerization and alcoholysis degree increased with the.
The adhesion of PVA with hydrophilic cellulose has good adhesion. In general, the degree of polymerization and alcoholysis degree is higher, the stronger bonding strength.
