摘要:
Continuous process for dyeing a textile thread by impregnation under pressure, followed by fluid extraction. The dye solution is applied to the thread in an impregnation enclosure, the thread then passes into a fluid extraction enclosure under which liquid is recovered to regenerate it and reuse it as dye. A regeneration enclosure is connected to an automatic color analyzer and to a calculation unit controlling the dosing apparatus for colorants.

The present invention relates to a process for the continuous dyeing of cellulose fiber 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 fiber-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 fibers.
摘要:
A device for guidance and/or support of filaments, particularly for textile machines working with wet filaments, comprising a guide and/or support (1) for the individual filaments (2) of a layer of filaments, mounted with the possibility of rotation on a carrying chassis (3) secured to the machine (4) or directly in bearings provided on the machine (4). The guide (1) for the individual filaments (2) of a layer of filaments is mounted retractably on the carrying chassis (3) secured to the machine (4) or in bearings provided on the machine (4). The invention is particularly applicable to the field of textile industry.
摘要:
The present invention relates to a detector for measuring the characteristics of a linear product of very great length relative to its other dimensions, on a production machine or the like. The detector operates without contact with the linear product and is provided with at least one means (1) having zones (2 and 3) for measurement relative to a mean position of the moving filament (4) and measuring the variation of the complex morpho-dimensional and/or positional characteristics of the filament (4), this latter varying, either by vibrating movement, or by displacement induced by the mean position of the axis of movement. The invention is applicable to the field of the measurement of the characteristics of linear products of very great length.

摘要:
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.

The invention concerns a sealing unit with rollers (7, 8) for the inlet (5) or the outlet of a treatment apparatus traversed by a conveyor belt (6) passing between the rollers, particularly an air and/or steam pressure apparatus. The sealing means between the frame (2) of the unit and the rollers are designed to be reliable, sturdy and easy to maintain. Specifically, they comprise an upper sealing device (29) and a lower sealing device (30), each one of which is in vertical contact with the corresponding roller (7, 8) and with a fixed element (27, 28). Each one of these devices may comprise a base plate (33) with a shaped slippery covering, consisting of a superficial strip (35) made of PTFE on a strip (34) of compressible flexible material. These devices may be removed without removing the rollers (7, 8). The contact means urging the sealing devices may have springs or hydraulic cylinders (31) or pneumatic cylinders.
摘要:
The invention concerns an apparatus for continuous heat treatment of textile thread. The apparatus is designed as a modular unit so that its size may be adapted to each need and treatment parameters adjusted according to its application. The apparatus comprises a conveyor belt (1) transporting thread (13) through a pretreatment chamber (7) and a treatment chamber (8). Each of these chambers (7, 8) comprises one or more enclosure modules (20, 30) containing one or more forced circulation units (21, 31). In the pretreatment chamber (7), each unit (21) causes pretreatment fluid to circulate in a closed circuit. The units (31) in the treatment chamber (8) cause treatment fluid to circulate and may function as an open circuit. Such an apparatus is useful for continuous heat treatment of textile thread, particularly for heat fixing either the physical structure of the thread or dyes.
摘要:
In the crimping process the yarns (1) are introduced continuously into a crimping machine (3) in which they are subjected to a compression which has the effect of crimping them.Before being introduced into the crimping machine (3) the yarns (1) are subjected to a presteaming operation in a chamber (6).Use especially for improving the bulk of the yarns before they are crimped.
摘要:
A heat treatment chamber for textile threads continuously treats the textile threads utilizing forced circulation units of a treatment fluid. The circulation units are these units being crossed consecutively by a conveyor belt that carries a lap of threads. Each circulation unit is provided with a blower and a closed circuit or an open circuit for the treatment fluid (air or steam). A heat exchanger is positioned near the conveyor belt, in such a way that the fluid crosses it and takes the desired temperature immediately before crossing the lap of threads. The heat exchanger can be formed of longitudinal tubes criss-crossed by heating or cooling fluid. Such a chamber is usable either to preheat the threads, to maintain them heated, or to cool them. The forced circulation units can ensure a gradual variation in the temperature of the threads in the same treatment chamber, or can enable a homogeneity to be obtained in a particular portion of the tunnel, by virtue of the communication between at least two forced circulation units that function in open circuit with the surrounding zone.
