Abstract

PURPOSE:To enable measurement of the number of roll even if cloth is in a dry, wet, spreaded or roped state by detecting, without contact, the roll end symbol drawn with a marking compsn. contg. metallic powder by using a metal detector and counting the same. CONSTITUTION:The roll end symbol drawn with a marking compsn. contg. metallic powder is detected by using a metal detector and the number of roll is measured. The metallic powder used is enumerated by permanent magnet powder, ferromagnetic powder, paramagnetic metallic powder, diamagnetic metallic powder and magnetic pigment compsn. The metallic powder having 60-500 mesh size is usable. A general detector meeting the characteristic of the metallic powder is used. A quick dry type synthetic resin paint compsn. used for ordinary paint is usable for the marking compsn. Since the metallic powder is coated by soft resin covering, the powder stays put without dislodging in the stage of refining, dyeing, printing, finishing, etc. and since the coating is powdery, it is flexible and the resin covering is not damaged. The inside wall, roll, mangle, etc. of the device are kept free from surface damage and the treating liquid is prevented from contamination.

Description

[Detailed description of the invention] The number of threads or the number of threads (hereinafter simply (
For details on how to count the inverse number, see Nariori,
Processing number, product number, reflection, written on the terminal of each fabric at the time of knitting,
A symbol such as thread usage (hereinafter referred to as an end mark) is written with a marking composition containing metal powder, and the metal powder contained in the mark is detected in a non-contact state by a total metal detector. This invention relates to a method for continuously measuring the total number of counters of a running fabric.

At the dyeing factory in W, all the pieces of fabric are tied together using sewing machines, etc.
Processing throughout the process such as scouring, dyeing, printing, finishing, and inspection,
Processing, inspection, etc. are being carried out. Controlling the machining numbers in these processes is the most important aspect of process control.

Conventionally, there is a method of measuring the number of runs of a knotted fabric using seams. For example, special
ー／／． Publication No. 299 Otsu describes a photoelectric method that utilizes the difference in light transmittance or light reflectivity between the fabric part and the tied part, and JP-A-299-23GG7 discloses a photoelectric method that utilizes the difference in light transmittance or light reflection between the fabric part and the tied part. A contact method using the difference in thickness is described. Also, Special Publication No. 5 Gu-1 399S and Utility Model Publication No. 3/-/, 2
Publication No. 239 describes a method in which a ferromagnetic metal piece is placed in a bag, attached to the entire connecting part, and the metal piece is detected electromagnetically.

Although the tip box method 1 has a high detection accuracy, it is only effective for dry and spread fabrics, and has the disadvantage that its usable range is narrow. Although the above-mentioned contact method is effective for fabrics in a wet and spread state, it has the disadvantage that it cannot be applied to fabrics with rope-like fabrics, ropes, lanes, etc. The electromagnetic method is also effective for fabrics in the spread and zero loaf state,
In addition, although this is a convenient method that can be used in both dry and wet conditions, ferromagnetic metal pieces must be attached to each ferromagnetic metal piece every time, which greatly complicates the work and also prevents the metal pieces from collapsing onto the inner wall of the processing equipment during processing. There are disadvantages in that the apparatus and fabric are damaged by collision with rolls, etc., and that they cannot be used in processes where mangles, rolls, etc. are used. In addition, recently there are many long pieces such as λ hikiori and q hikiori, and the boundaries between them are only marked, making it impossible to detect them with conventional seam detectors.

The inventors of the present invention have devoted themselves to research into a method that can eliminate all of these drawbacks and measure the counternumber in both dry and wet conditions, as well as in the spread state and rope state, and have found the symbol ( The present invention was developed by focusing on the fact that the color of the pigment remains undisappeared even after various treatments in the scouring, dyeing, printing, and finishing tube steps.

The present invention is a method for continuously measuring the counter number of a continuously running fabric, in which a counter mark written with a marking composition containing all metal powder is detected and counted without contact using a metal detector. It is characterized by

The metal powder used in the present invention includes permanent magnet powder such as magnetite, ferromagnetic metal powder such as iron, nickel, and cobalt, paramagnetic metal powder such as manganese, chromium, titanium, radium, and aluminum, bismuth, Diamagnetic metal powder such as zinc, lead, tin, copper, silver, etc., and metal oxides, chlorides,
Powders of water-unbathable compounds consisting of sulfates, nitrates, acetates, etc., or magnetic pigment compositions mainly composed of these, or metal powders with a size of θ to 00 meters/yu are used. can.

Magnetic force detectors that detect lines of magnetic force, electromagnetic induction detectors that detect lines of magnetic force generated by electric field formation, and high-frequency modulation detectors that use high-frequency modulation can be used as magnetic metal detectors. It is used according to the characteristics of the metal object.

As the marking composition, quick-drying synthetic resins and paint compositions used in ordinary paints can be used, and examples of synthetic resins include alkyd resins, butylated aminoaldehyde resins, phenolic resins, vinyl acetate resins, vinyl chloride resins, Film-forming resins such as epoxy resins, acrylic resins, hydrocarbon resins, urethane resins, vinyl butyral resins, and rincon resins are widely available.

This marking composition consists of the film-forming resin, a plasticizer such as butyl phthalate and tricresyl phosphate, an inorganic or M-organic coloring pigment, and an emulsifying and dispersing agent such as kerosene, kerosene, ethyl acetate, notyl ethyl ketone, and impropyl. It may be dissolved, emulsified, dispersed, or emulsified in a volatile organic solvent such as alcohol, thinner, or benone.

In addition, when a magnetic pigment is used as the coloring pigment, the mixing and kneading of the metal powder may be carried out in a small amount, and depending on the type of detector, mixing and kneading may not be performed at all.

According to the method of the present invention, since the metal powder is covered with a flexible ELL coating, it will not fall off during the scouring, dyeing, printing, and finishing tube processes, and since it is a powder, it is flexible. Even if the reeds or fabric become rope-like or are compressed by the mangle, the resin coating will not be damaged, the inner walls of the equipment, the surfaces of the rolls, the mangle, etc. will not be damaged, and the processing solution will not be contaminated. do not have.

When weaving the entire continuous lux sheath, which was filled in at the time of weaving using a marking composition consisting of % ON amount, the electromagnetic induction detector installed before and after the relaxation scouring machine was used to detect the When all the samples were counted, both in the dry state (before relaxing scouring) and in the wet state (after relaxing scouring), they counted well and showed the same value.

Furthermore, good results were also obtained when 3θθ mesh aluminum powder was used instead of the iron powder and a high frequency modulation detector was used as the detector.

When dyeing polyester brushed fabric g with a marking composition written with a marking composition consisting of 2577% in an endless manner using a liquid jet dyeing machine, the number of rotations of the fabric during dyeing was determined. When I checked it using the magnetic force detector that is always available in the machine, it showed a value that is 3/3 of the value (rpm) when using 7 permanent magnets.

From this, the marking composition used in the present invention has the same effect as when using conventional permanent magnet pieces, and has the advantage that it does not damage the inner wall of the dyeing machine.
