Problems solved by technology

The aromatic fabrics developed in the early stage are mainly carried out by post-finishing methods, but the aromatic fabrics prepared by this method have a short fragrance retention time and poor washability. Generally, the fragrance will be lost after 10 to 20 times of washing.

Embodiment 1

[0022] Raw material: take 92 parts of dried nylon 6 slices; 7 parts of fine-denier nylon masterbatch, add the second main group metal salt—calcium chloride, the addition amount is 10% of the weight of nylon slices; the particle size is 0.5-2 μm 1 serving of aromatic microcapsules;

[0023] Adjustment of equipment parameters: the hole diameter of the spinneret is 0.25mm, the length-to-diameter ratio is 1:3, the metal sand filter is 60-80 mesh; the position of the cluster point is 600mm away from the spinneret.

[0024] Process conditions: spinning box temperature 190°C, head pressure 12±0.3Mpa, ring blowing wind speed 0.35m / s, temperature 30°C, humidity 80%, spinning winding speed 4000m / min. Spinning under these conditions produces fine-denier nylon FDY filaments with aromatic function, the single filament fineness is 0.9dtex, the fragrance is strong and lasting, but the fiber spinnability is poor, the wool is more, and the production is more difficult.

Embodiment 2

[0026] Raw materials: take 95 parts of dried nylon 6 slices; 4 parts of fine-denier nylon masterbatch, add the second main group metal salt—calcium acetate, the addition amount is 10% of the weight of nylon slices; the particle size is 0.5 ~ 2μm 1 part of aroma microcapsule;

[0027] Adjustment of equipment parameters: the hole diameter of the spinneret is 0.15mm, the length-to-diameter ratio is 1:3, the metal sand filter is 60-80 mesh; the position of the cluster point is 600mm away from the spinneret.

[0028] Process conditions: spinning box temperature 215°C, head pressure 12±0.3Mpa, ring blowing wind speed 0.35m / s, temperature 30°C, humidity 80%, spinning winding speed 4000m / min. Spinning under these conditions produces fine-denier nylon 6FDY filaments with aromatic function, the single filament fineness is 0.8dtex, the fragrance is strong and lasting, the spinnability is greatly improved, and the production process is smooth.

Embodiment 3

[0030] Raw materials: take 95 parts of dried nylon 6 slices; 4.5 parts of fine-denier nylon masterbatch, add the second main group metal salt—magnesium sulfate, and the addition amount is 10% of the weight of nylon slices; the particle size is 0.5-2μm 0.5 parts of aromatic microcapsules;

[0031] Adjustment of equipment parameters: the hole diameter of the spinneret is 0.2mm, the length-to-diameter ratio is 1:3, the metal sand filter is 60-80 mesh; the position of the cluster point is 600mm away from the spinneret.

[0032] Process conditions: spinning box temperature 210°C, head pressure 12±0.3Mpa, ring blowing wind speed 0.3m / s, temperature 30°C, humidity 80%, spinning winding speed 4500m / min. Spinning under these conditions produces fine-denier nylon 6 FDY filaments with aromatic function, the single filament fineness is 0.7dtex, the fragrance is strong and lasting, the spinnability is good, and the production process is smooth.

Abstract

The invention relates to a method for producing a fine denier nylon FDY filament with aromatic function. The technical problem to be solved is to produce a filament that the filament number is between 0.5 and 1.0dtex, and the aroma retention time is long. In the production method, the weight ratio of three raw materials, namely nylon chips to fine denier nylon masterbatch to aromatic microcapsules is 1:5-20 percent: 0.5-10 percent. The process comprises the following steps of: 1) keeping steady pressure in a spinning component; 2) adopting 40-100-mesh metal sand for filtration; 3) adopting a spinneret plate, wherein the aperture of the spinneret plate is between 0.1 and 0.3mm, and the slenderness ratio is 2-4; 4) arranging an annealing device (1) behind the spinning component, and forming a windless region (2) with the height of between 20 and 40cm between the annealing device (1) and cross air blow (3); 5) ensuring that the position of a beam concentration point is 600 to 1,000mm away from the spinneret plate; and 6) ensuring that the spinning winding speed is between 3,000 and 5,000m / min.

Description

technical field [0001] The invention relates to an artificial filament, in particular to a production method of fine-denier nylon FDY filament with aromatic function. The obtained products can be used to develop high-end clothing, neckties, bedding and so on. Background technique [0002] With the advancement of synthetic fiber spinning technology and the improvement of people's consumption level, people put forward new requirements for the characteristics of synthetic fibers and their textiles. The functionality of conventional synthetic fibers is relatively single, which limits its application fields. Nylon is the earliest industrialized synthetic fiber variety. It has many excellent properties such as good elasticity, high strength, wear resistance, durability, small specific gravity, mildew resistance, moth resistance, etc., so it is welcomed by consumers, but with the progress of society With the improvement of people's living standards, people's requirements for the ...
