Embodiment 1

[0023] Step 1, network processing. The network fastness is required to be high, and the tightness is moderate and uniform. The key component of the network is the network device. In this case, the improved closed single-hole network device is used for the network screening. The installation position of the added network nozzle is consistent with the running direction of the yarn. In order to make the yarn enter the nozzle yarn path smoothly and not be easy to blow out, the nozzle must have a certain directionality, and it is usually installed at an inclination angle. In this example, the process parameters used for network processing are: air pressure 0.35Mpa, running speed of network wire is 220m / min.

[0024] Step 2, texturing. Texturing is actually a heat treatment for shaping. By adjusting and selecting the shaping tension (ie: positive overfeed, negative overfeed), setting temperature, and processing time, the elasticity of the network yarn is adjusted. In this embodim...

Embodiment 2

[0033] (1) Network processing. The process parameters are: air pressure 0.3Mpa, processing speed 200m / min.

[0034] (2) Textile processing. Temperature: 210°C, time: 60s, overfeed tension control: 5CN.

[0035] (3) Dyeing. High temperature and high pressure skein dyed black. Specifically, the dyeing process adopts a gradient constant temperature process, and the dyeing bath is prepared at room temperature. The dyeing bath is mixed with water, HAC, NaAC, dispersing chelating agent, dispersing leveling agent, and dyes. Polymer remover and keep the temperature constant for 5min, the heating rate is 2°C / min, then raise the temperature to 120°C and keep the temperature for 10min, the heating rate is 1.5°C / min, then raise the temperature to 130°C and keep the temperature for 35min, the heating rate is 1°C / min, and finally cool down To 85 ℃ and add acid reduction cleaning agent, constant temperature for 20min and overflow water washing.

[0042] (1) Network processing. The process parameters are: air pressure 0.25Mpa, processing speed 180m / min.

[0043] (2) Textile processing. Temperature: 230°C, time: 100s, overfeed tension control: 12CN.

[0044] (3) Dyeing. High temperature and high pressure skein dyed blue. Specifically, the dyeing process adopts a gradient constant temperature process,

[0045] Prepare the dyeing bath solution at room temperature. The dyeing bath solution is to mix water, HAC, NaAC, dispersing chelating agent, dispersing leveling agent, and dyes and raise the temperature to 85°C, add oligomer remover and keep the temperature constant for 6 minutes. The heating rate is 2°C / min, then raise the temperature to 20°C and keep the temperature for 6 minutes, the heating rate is 1.5°C / min, then raise the temperature to 130°C and keep the temperature for 30 minutes, the heating rate is 1°C / min, finally cool down to 85°C and add acid reduction cleaning agent, keep the temperature 20min and wash ...

Abstract

The invention provides a high-elastic yarn preparation method. The technical scheme is that interlaced yarns made of 100% of polyester materials is adopted, and the interlaced yarns made of 100% of polyester materials are treated through the following steps of interlacing processing, elasticizing processing, dyeing and hydrophilic after-treatment.

Description

technical field [0001] The invention relates to a high-performance material, in particular to a method for preparing a high-elastic yarn and a fabric made by using the same. Background technique [0002] Most of the commonly used elastic yarns contain spandex. Spandex is highly elastic and can be stretched 6 to 7 times, and can quickly return to its original state as the tension disappears. Its molecular structure is a chain-like, soft and extensible Polyurethane, which enhances elasticity by linking together hard segments. Adding spandex can increase elasticity and wear resistance, but adding spandex needs to be made into core-spun yarn or wrapped yarn, which increases the difficulty of yarn production and the fineness of yarn. In addition, it is difficult to dye spandex, and it is easy to appear whitening of spandex. affect the quality of the product. However, high elasticity and wear resistance are important indicators of many garment yarns, especially knitting sports s...
