2. Polyvinyl alcohol - Wikipedia

   en.wikipedia.org/wiki/Polyvinyl_alcohol

   Polyvinyl alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It has the idealized formula [CH 2 CH(OH)] n. It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing. It is colourless (white) and odorless.

   Acid dyes are water-soluble anionic dyes that are applied to fibers such as silk, wool, nylon, and modified acrylic fibers using neutral to acid dye baths. Attachment to the fiber is attributed, at least partly, to salt formation between anionic groups in the dyes and cationic groups in the fiber.

   There are multiple types of machine embroidery. Free-motion sewing machine embroidery uses a basic zigzag sewing machine. Designs are done manually. Most commercial embroidery is done with link stitch embroidery. [1] In link stitch embroidery, patterns may be manually or automatically controlled.

5. Emulsion polymerization - Wikipedia

   en.wikipedia.org/wiki/Emulsion_polymerization

   Some grades of polyvinyl alcohol and other water-soluble polymers can promote emulsion polymerization even though they do not typically form micelles and do not act as surfactants (for example, they do not lower surface tension). It is believed that growing polymer chains graft onto these water-soluble polymers, which stabilize the resulting ...

   The terms "water glass" and "soluble glass" were used by Leopold Wolff in 1846, [9] by Émile Kopp in 1857, [10] and by Hermann Krätzer in 1887. [ 11 ] In 1892, Rudolf Von Wagner distinguished soda , potash , double (soda and potash), and fixing (i.e., stabilizing) as types of water glass.

   types of hand sewing stitches. This is a list of stitches used in hand and machine sewing. The most common standard for stitches in the apparel industry is ASTM International ASTM D6193-16(2020) [1] The standard also covers various types of seams. Under this classification of stitches there are basic groups as follows:
