Protective apparel thread

 

Sewing the security thread can be used for flashing the documents of the special purpose and allows to protect against tampering with superior tailoring the properties due to the high bursting strength, low resposiveness its end and increased wear resistance and dyeing yarn dyes, visible both in daylight and infrared and ultraviolet rays. Protective apparel thread made of synthetic thermoplastic polymers and consists of 2-3 integrated twisted yarns, Straseni and twisted together. The original pneumatic function fittings composite yarns have the same linear density of 20-30 Tex, the number of pneumovirinae 20-50 per 1 m and twist 420-600 spins at 1 m, and one filament yarn colorless or colored visible in daylight, dyes, and other threads painted luminescense dyes, the concentration of the dye in each thread is 0.01 to 0.15 wt.%. table 1.

The present invention relates to garment industry, in particular to a garment dyed yarns of synthetic polymers for flashing the documents for special purposes and serves to protect them against forgery.

Known for sewing thread,Chennai in the direction the opposite direction of the twist twisted filament yarn [1].

Known sewing thread of twisted complex polyester yarns with a linear density of 11.0-27.7 Tex with a twist of 500-600 hills/m, which Straseni in 3 addition and twisted with a twist 320-456 hills/m and then subjected to heat-setting [2].

The disadvantages of this sewing threads are low tensile strength and bezopasnosti when sewing, not allowing its use as a protective threads in the flash document.

The present invention is the creation of protective apparel yarn, which can be used to protect documents special purpose of counterfeiting. Protective apparel thread should have improved tailoring of the properties, namely to have a high tensile strength, low resposiveness its end and high wear resistance. In addition, the thread should be painted as visible in daylight dyes and visible only in the infrared and UV rays, allowing you to use it as a security thread.

To achieve this goal in the present invention protective apparel yarn from synthetic thermoplastic polymers consists of 2-3 integrated twisted yarns, Straseni and twisted vmlo of pneumovirinae 20-50 per 1 m and twist 420-600 torsions 1 m, and one filament yarn colorless or colored visible in daylight, dyes, and other threads painted luminescense dyes, the concentration of the dye in each thread is 0.01-1.5 wt.%.

The inventive protective apparel thread thanks to the presence of dyes in an amount of 0.01 to 0.15 wt. %, luminescent in UV and infrared rays, can be used to protect documents for special purposes from the fake.

The original integrated pneumatic function fittings threads of the same linear density of 20-30 Tex with the number of pneumovirinae 20-50 per 1 m and a twist of 420-600 torsions of 1 m can improve its performance properties, namely, increased tensile strength, reduced breakage and reduced resposiveness end.

Protective apparel thread is produced as follows.

Granulated thermoplastic polymer (polyamide, polyethylene terephthalate) is mixed with the dye in a high-speed mixer with a paddle speed of 750-1000 rpm, mixing time from 3 to 10 minutes Using dyes, y UV-rays with a wavelength of 200-400 nm, or infrared rays with a wavelength of 700-1000 nm, or dye with reflection in the visible spectrum at a wavelength of 400-700 nm. Smesiteli is the heating of the polymer to 65-70oWith the friction of the granules to each other, so that the polymer softens and the dye binds with the surface of the polymer so that it doesn't happen its shedding from the granules.

Then mixed with the dye granulate polymer formed on the unit combined molding and extrusion at a speed of winding 2500-3500 m/min To dissipate static electric charge on the resulting thread is applied anhydrous lubricant in an amount of not less than 1 wt.%. Received freshly formed thread is subjected to orientation stretching in two stages with the multiplicity of deformation of 2.5-3.0 in the first stage and 1.2-1.5 second at a temperature of 75-95oAnd 140-170oRespectively.

Before winding on the package, the yarn is subjected to pnevmovodyanaya (pneumoperitoneum) compressed air with the formation of the "knots" of pneumovirinae in the amount of 20-50 per 1 m

Then the thread is wound on the package.

The initial complex yarns of different colors give a twist of 420-600 spins at 1 m, then their Trott together in 2-3 threads and subjected to second-hand twist. This multifilament yarn twist in one direction (e.g. the Z twist), and joining them together and twisting is carried out with the same twist in the other direction (S twist).

If the elemental threads for threads 30 Tex.

To relieve internal stresses in the threads and secure the twist with the aim of preventing the formation of scrutin when sewing the thread thermoablative at a temperature of 110-140oWith depending on the nature of the polymer. The heat treatment is performed on the hard packages within 2-3 hours. Heat treatment of filaments of nylon lead in inert gas or vacuum.

Packing of finished garments yarn weighs 200-300 g, the length of thread on it 3000-5000 m

Finish sewing thread contains one complex thread, which is colorless or colored visible in daylight dyes, which are used, for example, dyes antrahinonovye series, such as palamidi, polystrene, caprioli, levasole etc.

Other threads dyed with dyes, luminescense in the UV and IR rays. As such dyes can be used invisible in daylight dyes, for example, chelate complexes of alkaline earth and rare earth metals, or visible in daylight colors, glow in UV rays, for example rhodamine, oxazin, coumarin, and other Combination of dyes in the finished sewing thread set depending on the document type special purpose and requirements of the thread.

Concentration & rsquo; s the ASCI and glow.

The presence of high stable twist and pneumovirinae the original filament yarn ensures optimal contact conditions are ready sewing thread with a needle when sewing at high speeds and reducing resposiveness the end of the thread. Due to the presence of filaments 20-50 pneumovirinae ("knots") on the meter after the twist on it is formed a certain number of asperities, which reduce the friction between the thread and needle sewing machine. Thread less warms up the needle and the likelihood of breakage due to melting decreases. Can use threads to a high-speed sewing machines.

The table shows data on the properties of protective apparel filament in accordance with the claimed parameters. The ready threads determine the stability of the colors to physical and chemical influences [3] , the intensity of the luminescence relative to the benchmark and variation [4].

The proposed protective apparel thread has a high tensile strength, seamless transfer sewing and low resposiveness its end.

Test sewing thread for sewing machines "Kugler and domestic industrial high speed sewing machines showed that the package is ready sewing threads of 3000-5000 m perpetuated without breakage.tis from used fluorescent dye has a dotted appearance. The intensity of the luminescence relative to the benchmark is 5 points.

The variation of the thread1, which corresponds to the requirements.
