Description

High-temperature-resistant flame-retardant mixed yarn

Technical Field

The utility model relates to the technical field of textile, in particular to a high-temperature-resistant flame-retardant mixed yarn.

Background

The yarn is a textile, and is processed into products with certain fineness by various textile fibers, and is used for weaving, rope making, thread making, knitting, embroidery and the like. The yarn is as the important keeping away from of surface fabric processing, and the material of yarn often directly influences the quality of surface fabric, because the difference of yarn material, each kind yarn always has respective short board, and the yarn that often uses in fields such as industrial, commercial and domestic needs to possess fire-retardant high temperature resistant performance, but among the fire-retardant yarn of prior art, after some yarns weave into the surface fabric, elasticity and toughness are poor, and the wearing comfort is low.

Accordingly, there is a need for improvements in the art to address the above issues.

Disclosure of Invention

The present utility model aims to solve the technical problems in the related art to a certain extent. Therefore, one purpose of the utility model is to provide a high-temperature-resistant flame-retardant mixed yarn, optimize the fiber composition structure in the yarn, and improve the toughness of the yarn on the premise of ensuring the flame retardance and the high temperature resistance.

The technical scheme of the utility model is as follows:

the high-temperature-resistant flame-retardant mixed yarn comprises a core yarn, a plurality of first silk threads are arranged in parallel along the axial direction of the core yarn, each first silk thread is arranged outside the core yarn in a surrounding mode around a central shaft to form an inner silk thread layer, the outer parts of the first silk threads are twisted with a second silk thread and a third silk thread at intervals, the second silk thread and the third silk thread form a silk thread layer with a double-spiral structure on the outer periphery of the first silk thread, and the flame-retardant silk thread layer is coated outside the silk thread layer, so that the internal structure of the silk thread is tightly wrapped.

Further, a metal wire is arranged in the middle of the core yarn, and the core yarn is twisted outside the metal wire.

Further, the metal wire is nickel and drawn into a filament fiber shape.

Further, the four first silk threads are arranged in parallel along the axial direction, are sequentially distributed around the central axis of the core yarn at intervals, and each first silk thread is abutted against the core yarn.

Further, each first thread is made of cotton fibers.

Further, the second and third wires spirally wound outside the first wire are composed of polytetrafluoroethylene fibers and iced wires, respectively.

Further, the second yarn and the third yarn have different yarn diameters, i.e., different linear densities, and after twisting, a height difference is formed, thereby forming a gap.

Further, the flame-retardant silk thread layer wrapped outside the silk thread layer is formed by flame-retardant acrylic fiber.

The utility model has the beneficial effects that:

1. the metal wires are arranged in the core yarn, so that the toughness of the wires is improved, and meanwhile, the second wires and the third wires are twisted outside the first wires in a spiral winding mode, so that the toughness of the wires is further effectively improved.

2. The first silk thread is made of cotton fibers, so that the hygroscopicity of the silk thread is improved to a certain extent, and meanwhile, the third silk thread is made of ice silk, so that the moisture permeability of the silk thread is further improved.

3. The diameters of the second silk thread and the third silk thread, namely the linear densities, are different, and after twisting, the height difference is formed, and then gaps are formed, so that the air permeability of the knitted fabric is increased to a certain extent.
