The present application provides an annular liquid chamber 8 and compressed nitrogen output ports 7 arranged above and below, so that the oxygen content is extremely low in a relatively closed space, thereby providing a low oxygen space for the compounding of the reinforcing agent; it should be noted that, since whether to use a low oxygen space or a high oxygen space depends on the properties of the reinforcing agent, in the state where high oxygen is required, the compressed nitrogen output port 7 of the present application is equivalent to the compressed oxygen output port.

[0030] When in use, the cotton plucking machine body rotates around the rotating axis 2. Generally, a feed tooth can be set on the rotating track 3, and then a rotating motor is set on the rotating frame 4 to perform a rotating operation. During rotation, a negative pressure environment is provided in the raw material bin 1, and the cotton is also dispersed by the dispersing mechanism 14, so that the cotton can enter the external transmission pipe 10 after being dispersed.

[0031] In the second embodiment, based on the first embodiment, the effectiveness of the specific reinforcing agent of the present application is verified. Of course, the reinforcing agent of the present application can also be replaced by some other conventional cotton product pulps:

[0032] This application adopts the whole process of preparing yarn from raw cotton, and characterizes the role that the raw materials of the formula of this application can play by characterizing the strength changes of the yarn. Unless otherwise specified, the parameters used in each process are the same.

[0033] Cotton yarn is prepared as follows:

[0034] 1. Cotton cleaning: clean the impurities in the cotton. Before the cotton bales enter the cotton cleaning machine, open the cotton bales for preliminary cleaning to remove obvious impurities and foreign objects. The cotton cleaning machine loosens the cotton bales into a loose and free state, mixes and removes impurities, mixes the cotton evenly, and ensures the quality of the cotton yarn; the cotton grabbing device of this application is used for cotton grabbing. The specific formula of the reinforcing agent is shown in Table 1. After each substance is put into the shearing machine for mixing, it is immediately sprayed onto the fiber surface. A UV lamp is set at a later position, and the UV lamp illumination is controlled at 250μW / cm 2 ; The operating temperature is a first temperature, and after spraying, it is maintained at the operating temperature for a first time;

[0035] Table 1:

[0036]

[0037] 2. Carding: Carding the raw cotton into single fibers to increase the length and orientation of the cotton fibers, and then carding them into strips for subsequent drafting and other processes. The carding process can also further remove the fiber defects such as cotton knots, impurities, and short fibers that have not been removed by the cleaning process, help the fibers to be fully mixed, and improve the uniformity. After the cotton is carded into a cotton roll with a certain weight, length, uniform thickness, and good appearance, it is drafted into a cotton strip that meets the requirements. The drafting process will pull the cotton strips to a certain thickness and improve the parallel straightness of the fibers;

[0038] 3. Drawing: Improve the unevenness of long cotton strips, including four steps: combining, drawing, mixing, and slivering. After combining 6 cotton strips, stretch and thin them to a specified weight to further improve the straightness and parallelism of the fibers. Use combining and drawing to further evenly mix the fibers, mix them on the drawing machine, make them into well-formed coiled strips, and place them in the cotton strip barrel in sequence for subsequent operations; drawing is performed using the device described in this application;

[0039] 4. Preparation of roving: including drawing and twisting. Drawing will evenly stretch and thin the roving and further straighten and parallel the fibers. Then twisting is performed appropriately to make the roving have a certain strength, so as to facilitate the winding of the roving and unwinding on the spinning frame in the subsequent process. The coarse sand is finally set to a quantitative amount of 3g / 10m for molding; Example 4 is sprayed in the coarse sand preparation stage, specifically before the coarse sand is drawn, and a cavity is set so that the illumination of the ultraviolet lamp is controlled at 250μW / cm 2 ; The first temperature is maintained at 70°C, and the first time is 45s;

[0040] 5. Preparation of spun yarn: To obtain yarn with specified fineness and strength, it mainly includes drafting, twisting, winding and forming. Drafting will pull the coarse yarn to the required fineness, make the fibers straight and parallel, and add a certain twist to the yarn to enhance the strength of the spun yarn. The spun yarn obtained after drafting and twisting is wound on the bobbin to make a tube of a certain size and shape, which is convenient for handling and post-processing. The spun yarn adopts compact siro spinning, and the post-draft multiple is 1.2.

[0041] 6. Performance measurement: The single yarn breaking strength of the yarn was measured and entered into Table 2.

[0042] Table 2:

[0043] Serial number Single yarn breaking strength (cN / tex) 1 24.1 2 25.6 3 25.0 4 18.1 5 19.6 6 19.2 7 17.8 8 21.1 9 22.3 10 18.1 11 17.4

[0044] It can be seen that fiber repair during the cotton-grabbing stage has a good reinforcing effect, and the final yarn strength is greatly increased; and in the repair process, vinyl acetate and acrylic acid are indispensable, and in the presence of ethanol, it has a better repair effect.

In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0046] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
