Claims
- 1. A treated polyester fiber for reinforcing chlorosulfonated polyolefin, which consists of a polyester fiber coated with a treating agent comprising an isocyanate compound and/or an epoxy compound and with a treating agent which consists of a resorcinol/formaldehyde/latex mixture, wherein:
- 1) the molar ratio of the resorcinol to the formaldehyde is from 1/0.1 to 1/5,
- 2) the polymer component of the latex is a 2,3-dichlorobutadiene-containing polymer,
- 3) the weight ratio of the solid content of the latex to the sum of the resorcinol and the formaldehyde is from 1/100 to 1/1,
- 4) the amount of the 2,3-dichlorobutadiene-containing polymer solid content of the latex in the resorcinol/formaldehyde/latex mixture is from 5 to 50 wt %, and
- 5) the amount of a surfactant in the resorcinol/formaldehyde/latex mixture is from 0.5 to 2.5 wt %.
- 2. A process for producing a treated polyester fiber for reinforcing chlorosulfonated polyolefin, which comprises treating a polyester fiber with a treating agent comprising an isocyanate compound and/or an epoxy compound and then with the treating agent as defined in claim 1.
- 3. An elastic body comprising the treated polyester fiber as defined in claim 1 and a chlorosulfonated polyolefin compound.
- 4. The elastic body according to claim 3, wherein the chlorosulfonated polyolefin is the one obtained by chlorinating and chlorosulfonating an ethylene homopolymer or an ethylene-.alpha.-olefin copolymer.
- 5. The elastic body according to claim 3, wherein the chlorosulfonated polyolefin is an ethylene-.alpha.-olefin copolymer, wherein the chlorine content is from 20 to 33 wt %, and the sulfur content is from 0.3 to 1.5 wt %.
- 6. A process for producing an elastic body, which comprises laminating and/or mixing a chlorosulfonated polyolefin compound and the treated polyester fiber as defined in claim 1, followed by curing for bonding.
- 7. A treated polyester fiber for reinforcing chlorosulfonated polyolefin, which consists of a polyester fiber coated with a treating agent comprising an isocyanate compound and/or an epoxy compound and with a treating agent, which consists of a surfactant/resorcinol/formaldehyde/latex mixture, wherein:
- 1) the molar ratio of the resorcinol to the formaldehyde is from 1/0.1 to 1/5,
- 2) the polymer component of the latex is a 2,3-dichlorobutadiene-containing polymer,
- 3) the weight ratio of the solid content of the latex to the sum of the resorcinol and the formaldehyde is from 1/100 to 1/1,
- 4) the amount of the 2,3-dichlorobutadiene-containing polymer solid content of the latex in the resorcinol/formaldehyde/latex mixture is from 5 to 50 wt %, and
- 5) the amount of the surfactant in the resorcinol/formaldehyde/latex mixture is from 0.5 to 2.5 wt %,
- and the surfactant is at least one member selected from the group consisting of the following (a) anionic surfactants and (b) nonionic surfactants:
- (a) at least one anionic surfactant selected from the group consisting of a rosin soap, a disproportionated rosin soap, an alkyl sulfate, an alkyl benzene sulfonate, an alkyl naphthalene sulfonate, a dialkyl sulfosuccinate, a polyoxyethylene alkyl ether sulfate and a formalin condensation product of an alkyl aryl sulfonate, and
- (b) at least one nonionic surfactant selected from the group consisting of a polyoxyethylene alkyl ether, a polyoxyethylene higher alcohol ether and a polyoxyethylene alkylphenyl ether.
- 8. A process for producing a treated polyester fiber for reinforcing chlorosulfonated polyolefin, which comprises treating a polyester fiber with a treating agent comprising an isocyanate compound and/or an epoxy compound and then with the treating agent as defined in claim 7.
- 9. An elastic body comprising the treated polyester fiber as defined in claim 7 and a chlorosulfonated polyolefin compound.
- 10. The elastic body according to claim 9, wherein the chlorosulfonated polyolefin is the one obtained by chlorinating and chlorosulfonating an ethylene homopolymer or an ethylene-.alpha.-olefin copolymer.
- 11. The elastic body according to claim 9, wherein the chlorosulfonated polyolefin is an ethylene-.alpha.-olefin copolymer, wherein the chlorine content is from 20 to 33 wt %, and the sulfur content is from 0.3 to 1.5 wt %.
- 12. A process for producing an elastic body, which comprises laminating and/or mixing a chlorosulfonated polyolefin compound and the treated polyester fiber as defined in claim 7, followed by curing for bonding.
