Discussion of aqueous urethane acrylate oligomers with sulfoisophthalate on the antistatic hydrophilic finishing of different fabrics

Abstract

In this study, PEG(SE) containing sulfonic acid group was produced by transesterification of dimethyl 5‐sulfoisophthalate sodium salt (SIP) with PEG. The reactive urethane acrylate oligomers were synthesized by using SE as soft segment, isophorone diisocyanate (IPDI) as hard segment, and hydroxyethyl methacrylate (HEMA) as blocking agent. Their solution properties and thermal properties were investigated. Dipping process was carried out on polyethylene terephthalate (PET) fabric, polyamide (nylon) fabric, and cotton fabric for hydrophilic finishing and the effects of processing condition on the fixation behavior and hydrophilic property of treated fabric have been discussed. The conclusions are as follows: the particle size of oligomer solutions are about 45–90 μm, surface tension of solutions are below 43 dyn/cm, and they have smaller contact angle than water. The particle size, particle variance, and streaming current reading decreased, but the surface tension and contact angle enhanced upon increasing PEG molecular weight. The melting point of oligomer is 38°C–52°C and the glass transition point is −18°C to −25°C. In comparison with the fabric finishing, the add‐on of PET fabric is the highest, followed by nylon, then cotton. The durability of treated cotton fabric is the highest, followed by PET, then nylon. The hydrophilicity is most stable for nylon fabric with PEG molecular weight of 2,000, and cotton and PET fabric with molecular weight of 1,000. POLYM.

Practical two‐step chain extension method to prepare sulfonated waterborne polyurethanes based on aliphatic diamine sulphonate

“…Many strategies have been developed to incorporate sulfonic groups into the polyurethane chains for the preparation of sulfonated waterborne polyurethane dispersions (SWPU). Some researchers introduced the sulfonic groups into the soft segment or hard segment of polyurethane (PU) chains by combining sulfonated diols with conventional diisocyanates and polyols 14–17 …”

Influence of surface modification of zinc oxide nanoparticles on thermal behavior and hydrophilic property of PET–PEG composites

“…It may cause agglomeration of particles in copolymer matrix and decline in performance of the nanocomposites. To prevent the formation of agglomerated nanoparticles, surface modification of ZnO is necessary . However, in the literature mentioned previously, there have been few studies regarding the usage of ZnO nanoparticles in PET–PEG copolymers and the effect of surface properties of ZnO nanoparticles on the thermal and hydrophilic behaviors.…”

Preparation and characterization of cationic dyeable polycaprolactam modified with 5-sulfoisophthalic acid sodium and poly(ethylene glycol)

“…Nylon 6 has been modified, however, to improve its basic dyeability by forming the cationic dyeable polyamide (CD-PA) in the presence of a monofunctional, monosulfonated monomer, to provide nylon comprising molecules having at least a sulfonic group. [9][10][11][12] In this paper, 5-sulfoisophthalic acid monosodium salt (5-SSIPA) was found to be preferable. The modified molecules serve a dual role.…”
