PROBLEM TO BE SOLVED: To produce a cushioning carpet having insect repellent properties durable in washing and ready recyclability in combination by superposing a cushioning material containing low-melting fibers and insect repellent fibers of the same material-based polymer on the back surface of a base fabric comprising piles set therein and heat- treating the superposed materials. SOLUTION: This cushioning carpet is obtained by mixing 20-60wt.% low-melting fibers A comprising polyethylene terephthalate arranged as a core component and a copolyester, having a lower melting point than that of the core component by >=50 deg.C and arranged in a sheath component with insect repellent fibers B prepared by applying 0.01-1wt.% pyrethroid-based compound such as phenothrin and further a specific aminosilicone at (1:1) to (1:20) weight ratio based on the compound and a rust preventing agent such as disodium ethylenediaminetetraacetate at (1:0.5) to (1: 10) weight ratio to polyethylene terephthalate fibers, forming a laminated web, heat- treating the resultant laminated web at a temperature within the range of the melting point or above and below the melting point of other fibers, providing a cushioning material 4, superposing the formed cushioning material 4 on the back surface of a base fabric 2 comprising piles 1 set therein, heat-treating the superposed materials within the same temperature range as that described above. |
