The present invention realtes to a low temperature scouring and bleaching agent belonging to the pretreatment process technology field of the textile printing and dyeing industry, a manufacturing method thereof and a pretreatment process. Said low temperature scouring and bleaching agent consists of promoter QR2010 consisting of carbon tetrachloride, acetic acid esters, alkyl benzenes, emulsifying agents and scouring agents; promoter QR2011 consisting of potassium hydroxide, carbonates and penetrating agents; and promoter QR2020 consisting of acyls and nitriles activating agents and builders. Said three promoters are prepared using routine methods and are deposited solely. When used, the three promoters, together with hydrogen peroxide, are mixed according to different proportions to prepare solutions. Said low temperature scouring and bleaching agent is capable of annealing, boiling and bleaching a variety of cotton as well as cotton blending textiles at any temperature ranging from 40 DEG C to 80 DEG C, and being processed at different scouring and bleaching equipments, with a whiteness of higher than 80% and a capillary effect of 10-20 cm. Compared with the process in existing, the amount used of hydrogen peroxide activating agent is 1 / 7 to 1 / 5 of that originally used, the total energy consumption is reduced, the tonnage of used water is decreased, and billet flaws such as holes bleached by oxygen and lycra folded crepes sourced and bleached are avoided.

A machine for the discontinuous dyeing of fabric products in rope form comprises an autoclave (5) which contains a bath (10) for the treatment of the fabric and a unit for the introduction into the bath of dyes and any auxiliary chemical products contained in at least one tank (1). The introduction unit provides a recirculation duct (9) between two points on the bath (10) in which a mixing pump (4) is fitted, and provides for the introduction of the products coming from at least one tank (1) into the recirculation duct (9).

The invention relates to a fabric having both stab resistant and anti-ballistic properties. The fabric is made of yarn of a weight greater than about 500 dtex, and the fabric has a minimum shrinkage factor of at least about 1% achieved through a densification treatment. The invention further relates to a method of producing a such a fabric having the steps of agitating a fabric made of a yarn of a weight greater than about 500 dtex, substantially removing a spin finish from the fabric before, during or after the agitating step, and drying the fabric.

The invention relates to the field of suspended maintenance of steel-wire-ropes on a large-scale bridge and hydraulic engineering hoists, and discloses a steel-wire-rope-suspended maintenance machine. The steel-wire-rope-suspended maintenance machine comprises steel wire rope guide wheel oil seals, a chain wheel, a chain wheel adjustment shaft, a locking buckle, a locking buckle hanging rope, a forward-and-reverse-rotation electric winch, hairbrush rolls and the like, and is characterized in that a maintenance machine framework is rectangular-shaped or column-shaped or special-shaped and is formed by connecting the folding locking buckle, a left box and a right box. The left box and the right box are opened. Steel wire ropes are sleeved in two semicircular steel wire rope guide wheel oil seals. When the left box and the right box are closed, the locking buckle locks the steel wire ropes, the steel wire rope guide wheel oil seals and the steel wire ropes rub in a sliding mode, more than two hairbrush rolls are fixedly connected inside the left box and the right box, and a motor drives the hairbrush rolls to tightly contact the steel wire ropes and operates in a rub mode. Accordingly, not only dust, sand and aged old oil can be cleaned but also new oil can be efficiently and evenly covered on the surfaces of the steel wire ropes, and all kinds of defects of prior manual oil coating are overcome. The steel-wire-rope-suspended maintenance machine is reasonable in structural design, and improves operation levels and work efficiency.

The invention discloses a stress adjustment elasticized heat treatment process for PTT filament compound fabrics, comprising: wetting a cloth of fabric before heating setting to make the fabric be shrunk by four percent to fifteen percent, and then stretching the fabric by two percent to ten percent along warp direction or latitudinal direction, then eliminating the internal stress by heat treatment so that the internal structure of PTT fiber will reset with elastic recovery percentage raised and fiber structure and fabric size stabilized. In the meanwhile, changes of fabric structure and width size caused by the stress adjustment course can provide a basis for fabric design and formation of fine style of fabrics.

Apparatus and method for washing an elongate textile article of extended indeterminate length utilizes a containment structure defining a channel extending upwardly from a lower end to an upper end thereof, with a plurality of undulations spaced-apart from one another within the channel between the lower and upper ends thereof, each undulation extending transversely across the channel. A portion of the lengthwise extent of the traveling textile article is advanced transiently within the channel upwardly from the lower end to the upward end and across the undulations, while a substantially continuous supply of cleansing liquid enters the channel at the upper end to flow downwardly against the upwardly traveling portion of the textile article for cleansing thereof.

The invention discloses a dyeing machine, comprising a cloth conveying pipe, a cloth storage tank is arranged at a certain distance from the bottom of the cloth conveying pipe, a sealing door capable of sealing the cloth conveying pipe is arranged on one side of the cloth conveying pipe, and the cloth conveying pipe The feeding pump is connected to the feeding tank where the pigment is placed, and the cloth conveying pipe is connected to the heat exchanger through a circulating pump. It is characterized in that a cloth conveying roller, an overflow Nozzle, on the top of the cloth conveying pipe away from the sealing door, there is a pressing block for fixing and compressing the rope-like fabric. Tight block, overflow nozzle, cloth feeding roller, cloth storage tank and pressing block circulate dyeing in the cloth conveying pipe. Improving the traditional dyeing machine to obtain the same dyeing effect can reduce the number of cycles and improve the dyeing efficiency and dyeing uniformity of the dyeing machine.
