Embodiment 1

[0028] Example 1: The parts by mass of each component are: 20 parts of high-shrinkage nylon chips; 70 parts of dark-dyed nylon chips; 2 parts of titanium dioxide.

Embodiment 2

[0029] Example 2: The parts by mass of each component are: 30 parts of high-shrinkage nylon chips; 80 parts of dark-dyed nylon chips; 3 parts of titanium dioxide.

Embodiment 3

[0030] Example 3: The parts by mass of each component are: 25 parts of high-shrinkage nylon chips; 75 parts of dark-dyed nylon chips; 3 parts of titanium dioxide.

[0031] Working process of the present invention:

[0032] The nylon fiber produced by the invention has a trilobal cross section, which increases the irregularity of the fiber, improves the friction coefficient of the fiber, and increases the specific surface area of ​​the fiber; the use of high shrinkage nylon chips, deep dyed nylon chips, and titanium dioxide can make the nylon fiber The strength, wear resistance, and elastic recovery rate have been significantly improved, the production process is simple, efficient, and the product quality is high, which is conducive to production and promotion.

Abstract

The invention discloses a trilobal profiled super fine denier chinlon elastic fiber. The trilobal profiled super fine denier chinlon elastic fiber is prepared from, by mass, 20-30 parts of high-shrinkage chinlon chips, 70-80 parts of deep dyeing chinlon chips and 2-3 parts of titanium dioxide. According to the trilobal profiled super fine denier chinlon elastic fiber and a manufacturing technique thereof, the nylon fiber can be more reasonable and stable in structure and gains obvious improvement in intensity, abrasive resistance and elastic recovery rate; meanwhile, the manufacturing technique is simple and efficient, and the obtained products have high quality and is beneficial to production and popularization.

Description

【Technical Field】 [0001] The invention relates to the technical field of chemical textiles, in particular to the technical field of a trilobal shaped ultra-fine denier nylon elastic fiber and its production process. 【Background technique】 [0002] Nylon fiber has important applications in clothing and industrial applications due to its excellent strength, abrasion resistance, elastic recovery rate, and moisture absorption. Nylon fibers, especially nylon ultra-fine denier fibers, have a very strong market demand, and the quality of traditional craft products simply cannot meet the standards. Differential fibers are attracting more and more people's interest due to their unique structural properties, and the research on this type of fiber is also developing rapidly. Among them, special-shaped fibers are an important kind of differentiated fibers. In the process of forming synthetic fibers, fibers with non-traditional circular cross-sections or hollow fibers spun with special-shape...
