Embodiment 1

[0050] A kind of production technology of anti-ultraviolet bronzing ammonia air-coated silk, the concrete component that comprises and weight are as shown in table 2, are made by following steps:

[0051] S1: Methyl acrylate and fatty alcohol polyoxyethylene ether are mixed and stirred, the stirring speed is 700r / min, after stirring evenly, chitosan is added to mix and stir, the stirring speed is 800r / min, and the oil agent is obtained after stirring;

[0052] S2: Mix and stir copper sulfate, nano-titanium dioxide, mango extract, persimmon powder, cetyltrimethylammonium bromide, and stabilizer at a stirring speed of 1000r / min. After stirring evenly, add nylon slices, and then extrude High-temperature melting is carried out in the extruder. The screw extruder is divided into six temperature zones. The temperature of the high-temperature melting zone is 270°C-300°C-310°C-300°C-290°C-285°C. The speed of the screw extruder is 120r / min, pressure 65MPa, after distribution, spinning,...

Embodiment 2

[0055]Embodiment 2: a kind of production technology of the bronzing ammonia air-coated silk of anti-ultraviolet, and the difference of embodiment 1 is, concrete component and weight are different, and the concrete component that comprises and weight are as shown in table 2.

Embodiment 3

[0056] Embodiment 3: a kind of production technology of anti-ultraviolet nylon air-covered silk, the difference with embodiment 1 is that the weight ratio of nylon fiber and spandex fiber is 1:3.

Abstract

The invention relates to the technical field of textile, and particularly discloses a production process of ultraviolet-proof chinlon / spandex air-coated yarn. The production process comprises the following steps: mixing raw materials for preparing chinlon fibers, uniformly mixing, and then carrying out melt spinning to obtain chinlon fiber precursors, wherein the chinlon fibers are prepared from the following raw materials in parts by weight: 70-90 parts of chinlon chips, 2-4 parts of copper sulfate, 1-3 parts of nano titanium dioxide, 1.5-4 parts of mango extract, 2-3 parts of persimmon powder, 1-2 parts of hexadecyl trimethyl ammonium bromide and 2-4 parts of a stabilizer; cooling the chinlon fiber precursors, oiling after cooling, and winding after drying to obtain the prepared chinlon fibers; and taking spandex fibers as core yarn, and carrying out air coating on the spandex fibers and the prepared chinlon fibers to obtain chinlon / spandex air-coated yarn. The chinlon / spandex air-coated yarn has the advantage of being good in ultraviolet-proof performance.

Description

technical field [0001] The present application relates to the technical field of textiles, in particular to a production process of UV-resistant bronzing ammonia air-covered yarn. Background technique [0002] Nylon air-covered yarn is a yarn that draws the outsourced nylon fiber filament and spandex yarn through a certain type of nozzle at the same time, and is regularly sprayed by high-compression air to form a rhythmic network point yarn, which is covered by nylon air. The fabric obtained by silk spinning is soft and smooth, and is widely used in underwear, sportswear and other fields. [0003] The publication number is CN104195699A, and the Chinese patent application dated December 10, 2014 discloses a new type of nylon air-covered yarn and its production process, including nylon 6 chip feeding, melt spinning, side blowing cooling, and oiling. Gathering, winding, guide wire heating, cooling, false twisting, drafting and networking, and winding forming on the all-in-one ...
