Problems solved by technology

[0003] However, there is a problem during the covering process of the elastic yarn that the damage of the elastic yarn cannot be found at an appropriate time, so that a poor-quality product that has only the covered wire without the elastic yarn may be produced Wire
However, inorganic additives are not only added to rubber core yarns to avoid the above problems, but also inorganic additives are added to rubber core yarns to improve matting effect and anti-caking performance, so this problem cannot be fundamentally overcome
Furthermore, the traditional method has the disadvantage that it is almost impossible when the thickness of the elastic yarn is less than 40 denier, or when a low power device such as a portable UV irradiator is used to identify the damaged elastic yarn in the working position found this damage

Embodiment 1

[0033] At 85°C, under a nitrogen atmosphere, 518 grams of diphenylmethane-4,4'-diisocyanate was reacted with 2328 grams of polytetramethylene ether glycol (molecular weight: 1800) for 90 minutes to produce A prepolymer containing isocyanate groups located at its two terminals. The prepolymer thus formed was cooled to room temperature, and 4643 g of dimethylacetamide was added to the cooled prepolymer to produce a prepolymer solution.

[0034] Afterwards, at a temperature of 10° C. or lower, the solution (in this solution, 54 grams of propylene diamine and 9.1 grams of diethylamine were dissolved in 1889 grams of dimethylacetamide) was added to the pre- Polymer solution to produce segmented polyurethane-urea copolymer solution.

[0035] Add additives such as UV stabilizer, antioxidant, anti-yellowing agent, dye fastness improver, magnesium-based anti-blocking agent and titanium-based matting agent into the above segmented polyurethane-urea copolymer solution, and add 2 Coumar...

Embodiment 2 to 4

[0037] The procedure of Example 1 was repeated except that the thickness of the resulting elastic yarn was 20, 40 and 140 denier. The physical properties of the finally obtained elastic yarns are described in Table 1.

Embodiment 5

[0039] At 85°C, under a nitrogen atmosphere, 518 grams of diphenylmethane-4,4'-diisocyanate was reacted with 2328 grams of polytetramethylene ether glycol (molecular weight: 1800) for 90 minutes to produce A prepolymer containing isocyanate groups located at its two terminals. The prepolymer thus formed was cooled to room temperature, and 4643 g of dimethylacetamide was added to the cooled prepolymer to produce a prepolymer solution.

[0040] Afterwards, at a temperature of 10° C. or lower, the solution (in this solution, 54 grams of propylene diamine and 9.1 grams of diethylamine were dissolved in 1889 grams of dimethylacetamide) was added to the pre- Polymer solution to produce segmented polyurethane-urea copolymer solution.

[0041] Add additives such as UV stabilizer, antioxidant, anti-yellowing agent, dye fastness improver, magnesium-based anti-blocking agent and titanium-based matting agent into the above segmented polyurethane-urea copolymer solution, and make the final ...

Abstract

The present invention is a fluorescent elastic yarn and method for producing the same. The fluorescent elastic yarn can fluoresce sufficiently to allow a thin elastic yarn to be seen by the naked eye when ultraviolet light is irradiated to the fluorescent elastic yarn by adding a novel organic additive to a polymer or a spinfinish. Therefore, the fluorescent elastic yarn of the present invention is advantageous in that production of inferior covered yarns is prevented.

Description

technical field [0001] The present invention generally relates to a kind of fluorescent elastic core yarn (elastic yarn) and its production method, especially, the present invention relates to a kind of such fluorescent elastic core yarn and its production method: by means of novel organic additive Added to polymer or spinning oil, the elastic core yarn can emit enough fluorescence, so that the thin elastic core yarn can be seen by naked eyes when ultraviolet radiation is irradiated on the fluorescent elastic core yarn. Background technique [0002] The elastic yarn is applied to various fields, and the process of weaving and weaving the elastic yarn covered with natural fibers has been widely used in the prior art. Various elastic yarns such as core spun yarns (in which cotton or rayon is covered on the elastic yarn) and covered yarns (in which synthetic fibers Such as nylon and polyester coated on elastic core yarn) are used to produce elastic fabrics or woven items that ...
