Abstract
Disclosed herein is a process for producing a fibrous material for a member with which an ink-jet ink comes into contact, including the step of melt spinning a thermoplastic resin, the process comprising the step of treating a spun yarn by bringing it into contact with a glycol added with ethylene oxide.
Claims75
A process for producing a fibrous material comprising:
- providing a spun yarn by melt spinning a thermoplastic resin;
- and
- subjecting the spun yarn to a glycol treatment in which the spun yarn is contacted with an ethylene oxide adduct of a glycol having a cloud point of at least 65° C., whereby at least some releasable components of the spun yarn are emulsified or made water-soluble by the glycol treatment.
A fibrous material composed of a thermoplastic resin, which is treated by a glycol treatment in which an ethylene oxide adduct of a glycol having a cloud point of at least 65° C. is added, whereby at least some releasable components of the thermoplastic resin are emulsified or made water-soluble by the glycol treatment.
A process for treating an ink-absorbing member which can deliverably hold an ink-jet ink therein, the process comprising the steps of:
- treating a molding comprising a fibrous material composed of a thermoplastic resin with a treating agent containing an ethylene oxide adduct of a glycol having a cloud point of at least 65° C., whereby at least some releasable components of the thermoplastic resin are emulsified or made water-soluble by the treating agent.
A treating process for regenerating ink absorbing properties of an ink-absorbing member composed principally of a fibrous material, the process comprising the step of:
- treating the ink-absorbing member with a residual ink held therein with a treating agent containing an ethylene oxide adduct of a glycol having a cloud point of at least 65° C., whereby at least some releasable components of the fibrous material are emulsified or made water-soluble by the treating agent.
A fibrous material obtained by a process comprising the steps of:
- melt-spinning a thermoplastic resin comprising additives with spinning oil and forming a yarn;
- and
- replacing the additives and spinning oil contained in or attached to the spun yarn by treating the spun yarn with a glycol treatment containing an ethylene oxide adduct of glycol having a cloud point of at least 65° C.
A fibrous material for an ink-absorbing member holding an ink-jet ink, obtained by a process comprising the steps of:
- melt-spinning a thermoplastic resin comprising additives with spinning oil and forming a yarn, the additives and spinning oil giving effect to ink-jet properties of the ink-jet ink;
- and
- treating the spun yarn with a glycol treatment containing an ethylene oxide adduct of glycol having a cloud point of at least 65° C., the treating step being performed so that the ink-jet ink is free from any effect of the additives and spinning oil.
A fibrous material for an ink-absorbing member holding an ink-jet ink, obtained by a process comprising the steps of:
- melt-spinning a thermoplastic rein comprising additives with spinning oil and forming a yarn;
- and
- replacing the additives and spinning oil contained in or attached to the spun yarn by treating the spun yarn with a glycol treatment containing an ethylene oxide adduct of glycol having a cloud point of at least 65° C., and emulsifying the additives and spinning oil with the ethylene oxide adduct of glycol, so that the ink-jet ink is free from any effects of the additives and spinning oil.
