摘要:
A textile treatment composition comprises a water insoluble quaternary ammonium salt and a non-ionic surfactant containing at least one long-chain alkyl or fatty acid substituent and a hydrophilic group. The quaternary ammonium compound preferably has three large alkyl substituents of at least carbon atoms each and the surfactant may be selected from phosphine oxides, sulphoxides, or tertiary amine oxides, especially the latter. The compositions may be diluted with water and applied to textile materials especially wool, to give antistatic properties thereto. Compositions of the invention have lower soiling propensity than hitherto available compositions and they may therefore be applied to finished carpets, either in the piece or in situ applications.

Disclosed herein is the production of medical textile material with nanofiber surface that has transdermal drug release properties and that is coated with azithromycin active substance by using needle electrospinning method and ultrasonic spray pyrolysis (USP) technique. Specifically disclosed is a nanofiber medical textile material production method that includes the steps of preparing polymer solutions containing PVP (polyvinylpyrrolidone) with a concentration of 12 wt % and GEL (gelatin) with a concentration of 0.72 wt %; determining solution properties such as conductivity, viscosity, and surface tension, producing nanofibers from prepared polymer solutions by atmosphere-controlled horizontal needle fiber spinning (electrospinning) setup, obtaining PVP/GEL nanofibers after the fiber spinning process, thin film coating of the drug active substance on the obtained nanofibers, PVP/GEL nanofibers by the USP method, and cross-linking of both polymers to facilitate the final application processes of the drug-release material.

A polyethylene fiber characterized by having an intrinsic viscosity [η] of 0.8 dL/g or more and less than 5 dL/g; being composed of a repeating unit substantially derived from ethylene; having pores formed inside of the fiber; having an average diameter of the pores of ranging from 3 nm to 1 μm when the diameter is measured, by each pore being approximated by a column, at a contact angle of 140 degrees, in a mercury intrusion method; a porosity of the pores of ranging from 1.5% to 20%; and having a tensile strength greater than or equal to 8 cN/dtex.
摘要:
The present disclosure describes a surfactant treatment for a polyolefinic nonwoven fabric used to wrap items to be sterilized. The surfactant treatment consists essentially of carbon, hydrogen and oxygen atoms. The surfactant treated sterile wrap has a BFE after electret treatment and after sterilization of at least 97 percent. This treatment should produce fewer wet packs than the same fabric after electret treatment and after sterilization but without such surfactant treatment.
