Method for manufacturing carpet, latex and granular starch product that can be used therefor, and carpet.

摘要

The invention relates to a method for manufacturing carpet wherein at least one layer forming part of the carpet underlayer is formed from a latex of a natural or synthetic polymer wherein a granular starch product is included. The weight ratio of the granular starch product to the polymer of the latex (calculated on the dry substance) is in the range of 60/100 - 300/100 and the water content is chosen or set such that the weight ratio of the granular starch product to water is 60/100 - 200/100. From the foamed latex a layer is formed that is dried and cured, while the granular structure of the starch product is retained completely or almost completely. The invention also relates to a latex and to a precoated granular starch product that can be used for manufacturing carpet, and to carpet wherein a granular starch product forms the total or almost the total amount of filler present in at least one of the layers of the carpet underlayer.
