Abstract
A cloth containing a fiber having on a surface a polyacetal copolymer containing a prescribed amount of oxyalkylene unit(s), wherein the cloth exhibits a qmax value of at least 0.2 W/cm2, when the cloth is brought into contact with a heat storing plate of 40° C. under a contact pressure of 0.098 N/cm2 in an environment at a temperature of 20° C. and at a relative humidity of 65%, is superior in contact cold sensation, colorfastness, quick drying property and gloss.
Claims10
A cloth comprising a fiber having on a surface a polyacetal copolymer (X) comprising oxymethylene unit(s) and oxyalkylene unit(s) represented by the general formula (1) below,
- wherein the polyacetal copolymer (X) contains 0.2 to 5.0% by mole of the oxyalkylene unit(s), based on total moles of the oxymethylene unit(s) and oxyalkylene unit(s), and
- wherein the cloth exhibits a qmax value of at least 0.2 W/cm2, in which the qmax value indicates a maximum in a heat flux curve obtained by plotting, relative to time t, a heat flux q (t) per unit area which transfers from a heat storing plate of 40° C. to the cloth, when the cloth is brought into contact with the heat storing plate under a contact pressure of 0.098 N/cm2 in an environment at a temperature of 20° C. and at a relative humidity of 65%:
- wherein each of R0 and R0' represents a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, an organic group having an alkyl group having 1 to 8 carbon atoms, a phenyl group, or an organic group having a phenyl group, and a plurality of R0's and R0's are the same or different, and m represents an integer of 2 to 6.
