Abstract

Abstract A process for the continuous dyeing or printing of lengths of textile material, such as carpet panels having a portion which consists of shrinkable fibers that are set prior to the application of dyes or printing inks includes the step of forcing a hot liquid medium through the length of textile material. An apparatus for effecting this process includes a sieve drum through which the hot liquid medium flows from the inside towards the outside with the material lying on the circumference of the sieve drum.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 191 words
A process for the continuous dyeing or printing of a length of textile material, particularly a velour-type carpet panel having a base side and a pile side, the materials forming the base and/or pile sides including shrinkable fibers which are set prior to the application of dyes or printing inks, which comprises transporting the length of material with the pile side under pressure to a sieve drum having a perforated circumferential support surface, guiding the length of material onto the circumferential support surface of the sieve drum with the backside of the textile material lying on the support surface, forcing a hot liquid medium from within said sieve drum outwardly through the length of material in the direction of tips of the pile whereby the pile is spread and made upright during the flow of the liquid medium therethrough and the shrinkable fibers are set by said hot liquid medium with the pile in the spread and upright state and thereafter transporting the length of material with the pile surface not under pressure to and through a cooling zone to cool the length of material and the hot liquid contained therein.
Claim 2
Dependent Claim 191 words
A process for the continuous dyeing or printing of a length of textile material, particularly a velour-type carpet panel having a base side and a pile side, the materials forming the base and/or pile sides including shrinkable fibers which are set prior to the application of dyes or printing inks, which comprises transporting the length of material with the pile side under pressure to a sieve drum having a perforated circumferential support surface, guiding the length of material onto the circumferential support surface of the sieve drum with the backside of the textile material lying on the support surface, forcing a hot liquid medium from within said sieve drum outwardly through the length of material in the direction of tips of the pile whereby the pile is spread and made upright during the flow of the liquid medium therethrough and the shrinkable fibers are set by said hot liquid medium with the pile in the spread and upright state and thereafter transporting the length of material with the pile surface not under pressure to and through a cooling zone to cool the length of material and the hot liquid contained therein.
Claim 3
Dependent Claim 48 words
The process of claim 1, further comprising brushing the pile side of the length of textile material upon entry into said cooling zone and thereafter applying a suction to the base side of the length of textile material to drain cool liquid medium from said length of material.
Claim 4
Dependent Claim 31 words
The process of claim 1, wherein said cooling zone is provided by an air duct, said process further comprising contacting said length of textile material with air within said air duct.
