Problems solved by technology

[0003] The processing of fluffy nylon filament is mainly through texturing machine, false twister deformation processing, or through air deformation equipment, using air flow to blow the yarn, forming piles on the surface of the yarn, and the fluffy air textured yarn (ATY) The performance is better than that of low elastic yarn (DTY), but due to the low modulus and poor resilience of nylon fiber, the existing fluffy nylon filament still has a lot of room for improvement and improvement

preparation example Construction

[0026] Such as figure 1 Shown, a kind of preparation method of fluffy nylon filament comprises the following steps:

[0027] S1. Two or more nylon filaments with different dry heat shrinkage rates are transported from the nylon yarn tube 1 to the twister 3 through the first wire feed roller 2 for combined twisting, and the nylon filaments with different dry heat shrinkage rates are combined and twisted. The filaments are wrapped together so that the low-shrinkage nylon wraps the high-shrinkage nylon in a spiral shape, wherein the difference in dry heat shrinkage between the nylon filaments is not less than 10%;

[0028] S2. Adding a network to the twisted nylon filament through the network nozzle 4, so that the two ends of the nylon filament of a certain length are relatively fixed, wherein the number of network nodes per meter is 20 to 200;

[0029] S3. Transport the networked nylon filaments to the first hot box 6 for treatment through the second wire feed roller 5, and ove...

Embodiment 1

[0035] 1. Combining and twisting nylon raw material A and raw material B, the number of twists per 10 cm is 30, wherein, nylon raw material A is 150D / 72f PA6 FDY (its dry heat shrinkage rate is 5%), and nylon raw material B is 30D / 12f PA6 FDY ( dry its heat shrinkage rate 40%);

[0036] 2. Send the twisted nylon filament to the network nozzle to add network, and the number of network nodes per meter is 100;

[0037] 3. Send the nylon filaments added to the network to the first hot box for pre-shrinking at an overfeed of 40%, the temperature is 170°C, and the time is 5-10s;

[0038] 4. Deform the pre-shrunk nylon filaments with an overfeed of 20% to the air deformation nozzle, and the air pressure is 0.8MPa;

[0039] 5. Send the air-deformed nylon filament to the second hot box for shaping, the temperature is 150°C, and the time is 60s;

[0040] 6. Apply oil through the oil guide, and keep low tension during the oiling process;

[0041] 7. Wind the oiled nylon filament into ...

Abstract

The invention discloses a fluffy chinlon filament and a preparation method thereof. The fluffy chinlon filament is formed by processing two or more chinlon filaments with different dry heat shrinkage rates, and the dry heat shrinkage rate difference value between the chinlon filaments is not less than 10%. Compared with traditional chinlon filaments with a certain fluffy effect manufactured by directly performing air deformation on conventional chinlon FDY or POY, the fluffy chinlon filaments have the advantages that chinlon with different thermal shrinkage rates is twisted and combined, pre-shrunk after a network is added, and then subjected to air deformation processing to manufacture fluffy chinlon filaments, and the fluffy chinlon filament has the beneficial effects that the prepared fluffy chinlon filament is more uniform in diameter, better in fluffiness and less in long looped pile, and a prepared fabric product is fuller in hand feeling.

Description

technical field [0001] The invention relates to the technical field of textile chemical fibers, in particular to a fluffy nylon filament and a preparation method thereof. Background technique [0002] There are many types of chemical fiber filaments, and the manufacturing methods are complex and diverse. Common products include pre-oriented yarns (POY), drawn yarns (FDY), stretch-textured yarns (DTY), and air-textured yarns (ATY). Various methods such as twisting, texturing, and deformation endow fibers with certain characteristics to meet the needs of different fields and different products. There are more and more product categories. At present, the largest variety of chemical fiber filaments is polyester filaments, followed by nylon filaments. There is a certain difference in the performance of the two. Among them, the polyester filament has a high modulus and good resilience, and it has a certain bulkiness after elastic deformation, while the nylon filament has a low mod...
