The present invention relates to a process and a device for texturing yarns for rugs or carpet, upstream of a heat treatment unit. Process characterized in that it consists essentially of or comprises making, downstream of a rack, on at least one yarn, at least one microtexturing operation using a microtexturing machine, then depositing the yarn obtained at the outlet of the microtexturing machine, in bulk or in loops, in a free state, onto an intermediate device for accumulation and transport, carrying the yarn obtained to a downstream heat treatment unit.

Process and device for texturing yarns for rugs or carpet upstream of a heat treatment unit

A device for maintaining the crimping of textile fibers or filaments during subsequent setting treatment, located in a line for treating filaments by crimping and setting having a crimping machine (), whereby this device is connected to the outlet of the crimping machine () and consists of two perforated conveyor belts (), between which is fed the plug of textile fibers or filaments () coming from the crimping machine () and which pass through a setting oven or other setting machine to arrive at a filament uptake area. The device is provided with a member () for maintaining the continuity of the pressure on the plug of textile fibers or filaments () at the outlet of the crimping machine () and during the entire setting operation, whereby this member cooperates with the perforated conveyor belts ().

A thread accumulation device includes a discharge chute () for receiving and guiding a strand that is formed by a thread take-up device and a carriage for taking up a thread spiral, guided on the discharge chute () and resting on the end of the strand of the side that is opposite to the thread take-up device. At the outlet of the thread take take-up device, the discharge chute () is equipped with a transport unit () that adapts to the inside shape of the discharge chute (). The invention can be applied more particularly in the field of the textile industry, in particular the treatment of thread.

Thread accumulation device

Process for treating threads by knitting-unraveling includes: knitting several individual threads () on a multi-feed knitting machine (); carrying out one or more heat, chemical or other treatments, in one or more chambers (); carrying out, in an unraveling unit (), an unraveling with pulling on the first knit thread and winding or beaming the unraveled threads () individually or carrying out on these individual threads another treatment operation or a production operation, optionally with an intermediate accumulation of the threads. The invention can be applied more particularly in the field of the textile industry, in particular the treatment of threads, particularly texturing by knitting-unraveling.

Process for treating threads by knitting-unraveling

A process for pre-drying textile filaments after wet treatment and a device for practicing this process. The process consists essentially in applying simultaneously to a layer of wet filaments ( ) passing by on a conveyor ( ) with a permeable conveying surface, on the one hand, a mechanical squeeze-drying action and, on the other hand, a pressure difference by circulation of air through said layer ( ).

The present invention relates to a process for the continuous dyeing of cellulose fibre yarns with reactive dyes and to an apparatus for carrying out this process. The process essentially comprises steps of impregnating yarn which has been continuously unwound at high speed from one or several supports (1) and rewound onto one or several supports (3) with at least one fibre-reactive dye in aqueous solution and at least one alkaline reagent in aqueous solution, and fixing the dye. The invention can be applied especially in the technical field of dyeing cellulose fibres.

A device for expression of yarn, which has a comb (1) for guiding and expressing individual yarns of a layer of yarn. A compressed air blower (2) in line with each interval between two teeth (3) of comb (1) coacts with the comb (1) to cause the expression of excess moisture. The device is more particularly applicable to the field of the textile industry, in particular the field of washing and/or dying yarn.
