  • Antistatikmittel, Verfahren zu dessen Herstellung und dessen Verwendung zur Herstellung von antistatischen Beschichtungen
    1998
    Co-Authors: Rose K., Amberg-schwab S.
    Abstract:

    Antistatic contains organically modified silicic acid (hetero)polycondensate(s), obtained by hydrolytic (partial) condensation of silicon compound(s) undergoing hydrolytic condensation and optionally other elements of boron, aluminium, phosphorus, tin, lead, transition metals, lanthanides and actinides and/or precondensates derived from these compounds by the action of water or moisture, optionally in the presence of a catalyst or solvent. 0-35 Mole-% is derived from Si compounds of formula (I). The Antistatic contains 0-30 mole-% amine and/or quaternary ammonium compound(s), which contain organic group(s) with group(s) capable of polymerisation and/or polyaddition, and 0-30 mole-% salt(s) of optionally substituted (meth)acrylic acid, the total amount of (I), compounds and salts with respect to the condensate being 1-30 mole-%: ZaSiXbR(4-a-b) (I) X = hydrogen, halogen, hydroxyl, optionally substituted alkoxy, acyloxy, alkylcarbonyl, alkoxycarbonyl or an amino group NR'2; Z = R22N-(R3-N R2-)k-R3-, 1/m Am-R22N+-R3-, (HO-R3)2N-R3, Cl-SO2-R3-, (R2O)2P(O)-R3, 1/m Am-(R22N)2C=S+-R3-, 3/n Kn+(-OOC)2N-R3-N(COO-)-R3-, 1/m Am-H2C=C(R2)-R3-N+(R22)-R3- or 1/m Am- H2C=C(R2)-CO-O-R3-N+(R22)-R3- or a quaternary ammonium salt derived from one of these; R = optionally substituted alk(en)yl, (alkyl)aryl or arylalkyl; R' = H, alkyl or aryl; R2 = H, optionally substituted alk(en)yl, (alkyl)aryl or arylalkyl; R3 = optionally substituted alk(en)ylene or arylene; Am- = an anion with charge m; Kn+ = a cation with charge n; a, b = 1, 2 or 3; a+b = 2, 3 or 4; and k = 0, 1, 2 or 3. USE - Used for producing Antistatic coatings (claimed), and useful for a wide range of plastics. ADVANTAGE - Unlike existing Antistatics, these materials are useful universally applicable on plastics. They give a long-lasting, scratch-proof Antistatic Finish, adhere well and are not toxic. Production and application of the Antistatic is easy and cost-effective

  • Antistatic Finish of polyester fabric with chitosan
    2008
    Co-Authors: Wang Xi-liang
    Abstract:

    Antistatic Finish of polyester fabric with chitosan was carried out.Factors exerting influence on Antistatic property were analyzed,such as the amount of chitosan and crosslinker,curing time and temperature.The optimum conditions were defined through orthogonal experiments as follows: chitosan 2.0%,crosslinker 3 g/L and catalyst 4 g/L,liquor-to-goods ratio 20∶1,curing at 150℃ for 3 minutes.The antibacterial and moisture adsorption of polyester fabric Finished with chitosan were improved,but the handle became stiffer.

  • Antistatic Finish of polyester fabric with la 3 doped tio_2 sio_2 sol
    Dyeing & Finishing, 2010
    Co-Authors: Wang Ming
    Abstract:

    Antistatic Finish was carried out on polyester fabric with La3 +-dopped TiO2/SiO 2 sol.Finishing process was optimized by assessing Antistatic effect with induced voltage,half-life and electric charge density,and Antistatic mechanism of La3 +-dopped TiO2/SiO 2 nanosol was discussed.Results showed that Antistatic property of polyester fabric treated with TiO2/SiO2 sol increased obviously;ratio of TiO2 to SiO2 had little influence on Antistatic performance,while La3 +dopping could improve Antistatic property further;polyester fabric treated with TiO2/SiO 2 sol 0.1 mol / L or more,La3 +-dopping 0.3% and pad-dry-boiling process,had the optimal Antistatic property which could be still remained after 20 times laundering.

  • Coexisting Antistatic and water-repellent properties of polyester fabric
    Textile Research Journal, 2010
    Co-Authors: Tien-wei Shyr, Chin-hsing Lien, Ai-jing Lin
    Abstract:

    It is desirable for textiles to prevent static charges and to repel water. This work used nano-silver Antistatic Finish and fluorine water-repellent Finish in order to determine whether it is possible for Antistatic and water-repellent properties to coexist on a single sample of polyester fabric. The Antistatic and water-repellent fabric Finishes were each tested singly first; both Finishes were combined in each of three treatments, namely the one-bath, two-bath A, and two-bath B treatments. The Antistatic and the water-repellent properties of the Finished fabrics were evaluated by FTTS—FA—009 and AATCC 22 spray rating standards. The nano-silver and fluorochemical Finishes individually showed high performance properties on polyester fabric. It was found that the order of the Finishing processes has a significant effect on the Antistatic and water-repellent properties of polyester fabric. The two-bath B process treated polyester fabric, first with 5 wt% nano-silver antistat and then with 3 wt% fluorine wat...
