Problems solved by technology

[0004] In recent years, in order to continuously enhance the competitiveness of enterprises, our company has carried out research and development on the pure spinning series of nylon staple fiber. Due to the high specific resistance and high electrostatic coefficient of nylon staple fiber, it leads to poor formation of blown cotton laps and poor carding during the production process. After the process is formed into a web, problems such as electrostatic adhesion to the light roller, broken net, dropped net, broken sliver of the faucet, drawing process, and entanglement in the roving process make it impossible to work normally, and the production is extremely difficult.

Embodiment 1

[0034] A preparation process of nylon staple pure spun yarn, comprising the following steps: Nylon staple fiber health pretreatment → manual feeding → FA106 cotton opener → FA046 vibrating cotton box feeder → A076F single beater hand lapping machine →FA201B carding machine→FA317A head draw frame→FA317A finish draw frame→FA415A roving frame→EJM128K spinning frame→NO.21C automatic winder;

[0035] Preferably, the pretreatment step for the health preservation of nylon staple fiber is: heating pure water to 45°C, then adding an electrostatic agent and stirring evenly, then evenly spraying it on the raw material of nylon staple fiber, wrapping it with plastic cloth and placing it at 40°C for health preservation In-room health treatment for 24 hours for use in the next process; the mass ratio of the purified water to the electrostatic agent is 20:1;

[0036] Preferably, the beater of the FA106 opener adopts a comb beater, and the beater speed of the opener is 480r / min.

Embodiment 2

[0038] On the basis of Example 1, the FA046 vibrating cotton box feeder lowers the cotton feeding photoelectricity, adjusts the vibration feeding amount to the minimum, and adjusts the pressure of the pressing roller to the maximum;

[0039] Preferably, the beater speed of the A076F type single beater lapping machine is 960r / min, the speed of the lapping roller is 10r / min, and the weight of the cleaning flowers is 10.0KG.

Embodiment 3

[0041] On the basis of embodiment 2, the carding light roller of the FA201B type carding machine is equipped with a crawler-type cotton collecting device, and the carding tap is equipped with a leading guide roller;

[0042] Preferably, the production conditions of the FA201B carding machine during the carding process are a temperature of 28°C and a humidity of 75%;

[0043]Preferably, the cylinder speed of the FA201B carding machine is 326r / min, the cover plate speed is 127mm / min, the vehicle speed is 41m / min, the licker-in roller speed is controlled at 740r / min; the carding weight is 18.50g / 5m; MCC29P-1 cover card clothing is used for the board, AC2520×01850P cylinder card clothing is used for the cylinder, AT5605×05611 licker-in card clothing is used for the licker-in roller, AD4030BR×02090 doffer card clothing is used for the doffer, and the cylinder and the cover plate are 5 points apart 10‰, 9‰, 9‰, 9‰, 9‰ British silk, distance between licker-in roller and feeding board...

The process includes the following steps of healthcare pretreatment of the polyamide staple fibers, manual feeding, treatment on an FA106 cotton opener, treatment on an FA046 type vibrating cotton box cotton feeding machine, treatment on an A076F single beater scutcher, treatment on an FA201B type carding machine, treatment on an FA317A first drawing frame, treatment on an FA317A last drawing frame, treatment on an FA415A type roving frame,treatment on an EJM128K type spinning frame and treatment on a NO.21C type automatic winder.

Description

technical field [0001] The application belongs to the technical field of textiles, and in particular relates to a nylon staple pure spun yarn and a spinning process thereof. Background technique [0002] At present, natural and healthy lifestyles and outdoor leisure activities are increasingly being admired, and sports and leisure styles have also become an important direction for the development of fabric products. With its superior wear resistance and hydrophilicity superior to polyester, coupled with the development and application of other new technologies and processes, nylon products have received more and more attention in this field. [0003] Nylon staple fiber has a high volume specific resistance (the specific resistivity ranks second) and a large electrostatic coefficient, making its pure spinning production difficult. At present, there is no large-scale pure spinning of nylon staple fiber in China. [0004] In recent years, in order to continuously enhance the c...
