A device for wetting the fibrous product at a spinning and twisting machines
(57) Abstract:Usage: textile industry, spinning production. The inventive horizontally in the installed pipe in the upper part of the holes. Each hole has a ball freely rotatable in contact with him moving fibrous product. Supplied in a tube of liquid rotating the ball passes the product, moistening it. 3 Il. The invention relates to the textile industry and relates to a device for wetting the fibrous product at a spinning and twisting machines.A device for wetting the fibrous product at a spinning and twisting machines, containing horizontally installed between supporting a pair of rollers and twisting the body of the machine and associated with means for supplying a wetting fluid pipe with holes in the top and mounted for contact with a fibrous product of the wetting elements.However, moving the fibrous product relative to the wetting element determines the possibility of false hood when its linear density that otritsatelnomu dissemination twist product from twisting body to feed a pair of rollers, that also reduces the quality of the product.The aim of the invention is to improve the quality of the fibrous product by preventing uncontrolled pull wetting and ensure the dissemination of twist fibrous product through the zone of wetting to the feed roller pairs machines.This goal is achieved by the fact that each of the wetting element is a ball mounted in the hole in the upper part of the tube with the possibility of free rotation upon contact with the moving fibrous product.In Fig. 1 shows a diagram of the location of the device on a spinning machine of Fig. 2 is a device top view of Fig. 3 - section a-a in Fig.2.The device comprises a tube 1, a horizontally installed between supporting a pair of rollers, in this case, the final pair of rollers 2 exhaust device of the spinning machine, and torsional body (not shown). The pipe 1 is connected with the water pipe 3 with means for supplying it the wetting fluid and has at the top of the hole, which has a wetting elements. Each of the wetting element is a ball 4, is placed in the hole at the top of the pipe with the possibility of free rotation wuerch relative to the longitudinal axis of the pipe.The device operates as follows.Coming out of the exhaust pair 2 exhaust device fiber sliver 5 is in contact with the ball 4, washed the inside of the tube 1 is supplied to it by the liquid, and comes to twisting the body of the machine, which she twisted into yarn.Moving sliver contact with the ball without slipping with respect to it, causing it to rotate, with the ball in its rotation carries the fluid from the pipe on Micco, moistening it. No relative displacement sliver and ball prevents uncontrolled pulling the sliver. In addition, the possibility of rotation of the ball in the hole of the pipe along a complex trajectory in different directions moving engraved facilitates the passage of its twist through the contact zone of the sliver with a wetting element and dissemination twist to the final pair of exhaust actuator, the reduced yarn breakage.The design of this device allows you to improve the quality of the fibrous product by preventing uncontrolled stretching in the area of wetting and ensure the passage through it of twist of product to feed a pair of rollers. A DEVICE FOR WETTING the FIBROUS PRODUCT AT PROSPECT who inim body of the machine and associated with means for supplying a wetting fluid pipe with holes in the top and mounted for contact with a fibrous product of the wetting elements, characterized in that, to improve the quality of the fiber product by preventing uncontrolled pull wetting and ensure the dissemination of twist fibrous product through the zone of wetting to the feed roller pairs of the machine, each of the wetting element is a ball mounted in the hole in the upper part of the tube with the possibility of free rotation upon contact with the moving fibrous product.
FIELD: textile industry, in particular, non-circular weaving equipment, for example, weaving units.
SUBSTANCE: apparatus has shaft disposed between columns and adapted for carrying of rotary lever with rotating pressure roll, and spiral spring. Shaft is immovably fixed between flat columns attached by means of bolt-type protrusions to vertically arranged base. Spiral spring is mounted on shaft and spring ends are fixed on rotary lever and on one of columns. Shaft is made stepped and is equipped with basic end portions terminating in threaded parts. Flat columns have rectangular portions continued with bolt-type protrusions. Column arranged at the side of spring end has cylindrical opening for accommodation of rectilinear end of spring. Cylindrical recess provided in rotary lever hub aperture on its internal surface at the side of arrangement of spring is adapted for accommodation of rectilinear end of spring.
EFFECT: improved operating characteristics and operating conditions.

SUBSTANCE: according to the method, broken thread exiting drafting device is soaked in solution, by means of its compaction, rove is formed, and formed rove is wound onto reels of cross winding, which are chemically treated and then processed into yarn. Broken thread is soaked with electrochemically activated aqueous solution with oxidation-reduction potential from minus 1000 mV to plus 1000 mV, acidity of 2-11 pH at the temperature of 16-40°C, and produced rove, not earlier than in 30 minutes after the formation, is processed into yarn.
EFFECT: faster process of rove formation and preparation for spinning, reduced power inputs from 4200 kJ/kg to 3 J/kg and water consumption for chemical treatment of rove, rejection of chemical agents, which makes it possible to reduce costs of recycling coming as a result of chemical treatment of rove by solutions, and elimination of bulk and expensive equipment for chemical treatment of rove.

SUBSTANCE: invention relates to the textile industry, in particular to flax spinning production, where, at the last manufacturing step, to produce flax yarn the semi-finished in the form of roving is used. The method of formation and preparing flax roving for spinning, according to which, broken thread exiting drafting device is soaked in electrochemically activated water solution with an oxidation-reduction potential from minus 1000 mV to plus 1000 mV and the acidity of 2-12 pH at the temperature of 16-40°C. And the wetting is carried out directly to the cavity of the chemical reactor designed for obtaining electrochemically activated water solution.
EFFECT: invention enables to reduce the time, to reduce energy and water consumption for chemical treatment of roving, refuse chemicals which can lead to lowering disposal costs resulting from chemical processing of roving, solutions.
