it is understood that: sorbitol (sorbitol) is a white hygroscopic powder or crystalline powder, flakes or granules, odorless. depending on the crystallization conditions, the melting point changes in the range of 88 to 102°c, and the relative density is about 1.49. easily soluble in water (1g dissolves in about 0.45ml water), slightly soluble in ethanol and acetic acid. it has a refreshing sweetness, the sweetness is about half that of sucrose, and its caloric value is similar to that of sucrose. sorbitol liquid is a clear, colorless, syrupy liquid with a sweet taste, neutral to litmus, and miscible with water, glycerin and propylene glycol.
applications of sorbitol in the textile industry:
sorbitol and iron the chelation effect of copper ions is often used in highly alkaline fabric rinsing solutions;
in the solution formulation to improve the washing and wear resistance of cotton fibers, sorbitol can be used as a scavenger for unreacted formaldehyde and toughening agent after stain removal.
sorbitan monooleate is often used as a dry cleaning agent in combination with anionic surfactants.
the condensation product of sorbitol and epichlorohydrin can be used as a fabric softener after reacting with triethylene triamine hydrazine stearate.
