Requirements are different. Water absorption and water retention, good resin, its thickening ability is not necessarily the best. And synthetic thickeners, metal ions in the electrolyte and pH car window flag poles manufacturers on water absorption and water-retention capacity. Heavy metal ions and-COO-to form insoluble salt, reduce water absorption and water-retention capacity. The presence of electrolytes (such as neutral inorganic salts) will reduce the osmotic pressure, car window flag poles manufacturers reduce the hydration of ions and reduce the degree of stretching of the mesh structure, will reduce water absorption and water-retention capacity. the effect of pH is also great, in acidic media, a COOH ionization diminished capacity, absorbent and water-retention capacity also decreased significantly.
The fourth quarter of finished product testing and packaging
Fabrics after dyeing, , finishing the last process is the inherent quality and appearance quality of the product to be tested, then the product rating classification based on test results, between into the decoration, , folding, posted trademarks fight with flower color, folded, rolled or rolls, packaging, , and finally sent to the factory or warehouse.
First, the quality inspection requirements car window flag poles manufacturers
(A) the intrinsic quality inspection
(1) the taking of life and use characteristics of the physical and mechanical properties is directly related to the fabric is a very important indicator. Often test the project following several car window flag poles manufacturers
(1) Length: required length of the match, and dyeing cloth is generally
and dyeing cloth standard width = fabric Standard width × width processing coefficient.
(3) Density: root number to each 1Ocm fabric yarn, fabric Standard Density processing coefficient multiplied by the Density is the density of warp and weft of and dyeing cloth. Specified in Table 4-2.

(4) shrinkage: quality assessment indicators, sub-shrink-proof products and general product categories. Shrinkage related to the dimensional stability of the finished garments are shown in Table 4-3 and Table 4-4.
The provisions of Table 4-3 of the shrink-proof finishing product shrinkage
Shrinkproof category shrinkage of <%> is not greater than
