Embodiment 1

[0022] Spread the skein on the working platform of the skein balance room (spreading thickness 4-5cm); close the balance room to start the constant temperature and humidity system, and gradually increase the temperature and humidification, control the heating rate at 0.5-1.0°C / min, so that the temperature Gradually rise to 35±1°C, control the relative humidity to 50±3%, and keep the constant temperature and humidity for 40 minutes; then gradually lower the temperature, and control the cooling rate at 0.5-1.0°C / min; after cooling to room temperature, keep the time for 15 minutes; Afterwards, open the balance room to ventilate for 12 minutes, and the next process can be carried out after the surface of the skein has been completely dried and shrunk.

Embodiment 2

[0024] Spread the skein on the working platform of the skein balance room (spreading thickness 4-5cm); close the balance room to start the constant temperature and humidity system, and gradually increase the temperature and humidification, control the heating rate at 0.5-1.0°C / min, so that the temperature Gradually rise to 25±1°C, control the relative humidity to 90±3%, and keep the constant temperature and humidity for 20 minutes; then gradually cool down, and control the cooling rate at 0.5-1.0°C / min; after cooling to room temperature, keep the time for 20 minutes; Then increase the temperature and humidify again, so that the temperature gradually rises to 45±1°C, the relative humidity is controlled at 70±3%, and the holding time is 20 minutes; then the temperature is gradually lowered, and the cooling rate is 0.5-1.0°C / min; After 25 minutes, open the balance room for inspection, and the next process can be carried out after the surface of the skein has been completely dried ...

Abstract

The invention relates to a pretreatment method for dyeing of nylon skein. According to the technical problem, the provided method has the characteristics of safety, reliability, good effect, simpleness in operation, energy saving and environment protection and comprises the following steps of: (1) spreading the nylon skein out on a working platform in a skein balancing chamber with a constant-temperature and constant-humidity system, wherein the spread thickness is less than 5cm; (2) closing a door of the skein balancing chamber to seal the skein balancing chamber, heating and humidifying till the temperature is 18-45 DEG C and the relative humidity is 60-90% wherein the heating rate is less than 1.0 DEG C / min; then keeping the temperature and the humidity constant for 20-50min; (3) cooling to room temperature and keeping for 15-25min, wherein the cooling rate is controlled to be less than 1.0 DEG C / min; and (4) opening the door of the skein balancing chamber, circulating indoor and outdoor air for at least 10min to ensure that the surface of the nylon skein is contracted and dried, and finally packaging and delivering the finished products.

Description

technical field [0001] The invention relates to a processing technology for textile products, in particular to a pre-dyeing processing method for nylon hank yarn. Background technique [0002] In the textile industry, nylon high-elastic yarn is a kind of textured yarn. It is stretched by a stretching roller and twisted by a self-false twister on a stretching texturing machine using a torsional false twisting method, and is shaped by a hot box, etc. crafted. The crimp rate of textured yarn is generally 30% to 50%, so it has a certain degree of strength and bulkiness, and its high shrinkage characteristics can meet various design requirements and appearance effects of the fabric. Due to its good strength and toughness, excellent wear resistance and resilience, nylon high-elastic yarn is widely used as a material for socks, stretch shirts, etc. The elasticity of high elastic yarn will be significantly reduced. In order to avoid the loss of elasticity when nylon is dyed at hi...
