Luminous yarn thread
Forms and uses of luminescence:
Material that glows automatically in darkness.
Long-lasting luminescent yarn luminous thread first absorbs all kinds of light and heat, converts them into light energy storage, then automatically emits light in darkness, realizes luminescent function by absorbing all kinds of visible light. The product of luminous does not contain radioactive elements, and can be recycled indefinitely, especially for short-wave visible light, sunlight and ultraviolet light (UV) under 450 nanometers. It has strong absorption capacity.
Noctilucent yarn luminous thread has a wide range of uses, such as jewelry, textiles, wigs, ribbons, trademarks and so on.
2. Basic pattern:
Long-acting noctilucent yarn luminous thread has long-acting 6 colours and common 1 colours. It can be mixed with various colours of fluorescent agent.
3. Application of reference colors of luminous thread:
Yellow-green light, blue-green light, sky-blue light, purple light, white light and red light. Fluorescent pigments and dyes can be used to adjust the color before and after luminescence, but the luminous effect will be reduced.
5. Preservation of thermochromic yarns luminous thread:
This product should be kept in cool, dry and completely dark conditions. Under the above conditions, the performance of most kinds of noctilucent luminous thread yarns did not deteriorate significantly after 5 years storage.
Luminous thread is twisted by night optical fiber dimension, while night optical fiber dimension is a new functional environmental protection material made of rare earth luminescent materials.
When night optical fiber dimension absorbs light in sunlight for 5-10 minutes, it can store light energy in the fiber. When luminous thread is placed in darkness, it will continue to shine for more than 12 hours.
When it shines, the brightness is not dazzling, the function is strong and the material is strong.
It does not contain any radioactive substances.
It is non-toxic and harmless.
It has good stability and weatherability. The precursor is white. There are other colors, such as red, yellow, blue, green and so on. What colours are absorbed outside during the day, and at night you will see that they present different light.
The common specifications of luminous thread sewing thread are 150D/2.
The main specifications of polyester noctilucent yarn luminous thread are 150D, 150D twisting, 300D twisting, 21S 21S/2.
The main specifications of nylon glossy yarn luminous thread are: 120D, 600D, 600D twisting
Polypropylene noctilucent yarn luminous thread mainly has: 300D, 600D, 900D
Long-lasting luminescent pigments first absorb various light and heat, convert them into light energy storage, and then automatically emit light in the dark, through the absorption of various visible light to achieve luminescent function, the product does not contain radioactive elements, and can be recycled indefinitely, especially for short-wave visible light, sunlight and ultraviolet light (UV) below 450 nanometers. Luminous thread has strong absorption capacity.
Research on luminous thread fiber dimension and yarn performance and fabric development
The basic properties of nocturnal fiber luminous thread, such as cross section and longitudinal morphology, infrared spectra, single fiber strength and nocturnal light properties, were studied. The single luminous thread yarn strength, hairiness, moisture content, heat resistance, acid and alkali resistance of nocturnal fiber dimension yarn luminous thread were tested.
At the same time, the knitting surface of 16.7 tex nocturnal fiber dimension pure spinning yarn was tested.
Finally, the luminous properties of the fabric thread were tested.
The results show that the knitted fabrics developed by the night optical fiber dimension have good luminous thread performance, thick and broad fabrics, and can be used for the development of knitted fashion underwear and sweaters.
Key words: Night fiber dimension; luminous thread yarn linear properties; knitted fabrics; luminous thread properties
Night optical fiber luminous thread dimension is a new type of functional fiber with daytime light storage, night emission residual light, and long-term cycle light storage.
The principle of luminous thread is to add rare earth materials in the spinning process, so that the luminous thread yarn has the special function of night light. In this paper, polyester-based noctilucent fiber Uyghur pure spinning yarn is taken as the research object.
The basic properties of noctilucent fiber luminous thread uyghur and its yarn are tested and studied.
A knitted fabric luminous thread with air layer structure is developed using noctilucent fiber Uyghur yarn as raw material.
Basic properties of 1 fiber
1.1 Section morphological structure of luminous thread
Neoscope JCM-5000 H Benicon desktop scanning electron microscope was used to scan and photograph the cross-section and longitudinal morphology of the night optical fiber dimension. The scanning results were magnified 1100 times. The surface of nocturnal optical fiber dimension is smooth, the cross section is regular circular, with fine luminous threads, and there are fine rare earth particles.
1.2 Infrared spectrum analysis
Using american nicolet 5700 fourier
Raw materials for knitted noctilucent yarn luminous thread:
Leaf infrared spectroscopy was used to measure the infrared spectra of night optical fibers and polyester fibers luminous thread. The infrared spectra of night optical fibers and polyester fibers are similar, but the absorption peaks of night optical fibers are less, which indicates that the heavy metal ions in rare earth elements in night optical fibers luminous thread have an effect on the absorption peaks.
1.3 Single fiber luminous thread strength
In dry state, the breaking strength, breaking elongation and tensile length of the fibers luminous thread were tested by YGO04E single-fibre tensile machine.
The pre-tension was 0.4 cN, the distance between the clamps was 20 mm, the drawing speed was 20 mm/min, and the average value was obtained 30 times.
The test results are as follows: the average fracture strength is 9.60 cN and the average fracture strength is 4.17 cN/dtex. The elongation at break is 39.33% and the elongation at break is 7.87 mm.
Night fiber luminous thread has better strength, higher breaking strength and higher elongation at break.
1.4 Luminous thread performance
The luminous thread color of the night optical fiber dimension studied in this paper is light yellow-green. After irradiating the night optical fiber dimension under sunlight or lamp for 10-30 minutes, it is placed in a darker environment, which can sustainably emit light for 6-8 hours, and can be recycled indefinitely. Night optical fiber luminous thread dimension in bright (natural state) effect map and in the dark luminous effect map.
2. Testing of luminous thread yarn basic properties
Ultra-pure spinning of nocturnal optical fibers luminous thread with linear density of 16.7 Lex was studied.
2.1 Single luminous thread yarn strength
YC020A electronic single luminous thread yarn strength tester was used to test the single yarn strength of night fiber Uygur pure spinning. The distance between chucks is 500 mm, the drawing speed is 250 mm/min, and the average port is measured 25 times. The test results are as follows: average fracture strength 630.38 cN fracture elongation 190.58 mm average fracture elongation 38.12%.
The breaking strength and breaking elongation of nocturnal fiber luminous thread dimension pure spinning yarn are bigger. It belongs to high strength and high elongation yarn, which fully meets the requirements of knitting luminous thread yarn.
2.2 Feathers of luminous thread
Using the hairiness index, average length of hairiness, CV value of hairiness variation coefficient and hairiness H as evaluation criteria, yarn hairiness tester YG173 was used to test the hairiness of nocturnal fiber Uygur pure spinning.
The test degree is 10m, the yarn traveling speed is 30m/min, and the test times are 10 times.
From Table 1, it can be seen that the hairiness of night fiber dimension yarn is very small, the average hairiness length of 1 mm is only 10.60, and the hairiness length of more than 10 mm is not good. It shows that the quality of night fiber luminous thread dimension yarn is very good, which is beneficial to the later weaving process.
2.3 Moisture content for luminous thread
JA3003N electronic balance is used to produce the luminous thread yarn, and the yarn strength decreases obviously. It can be concluded that the night fiber luminous thread dimension yarn is acid and alkali resistant, but not strong alkali resistant.
