[0029] A fabric weaving process comprises the following steps:

[0030] S1: introducing the grey cloth into the desizing device, injecting the desizing agent into the desizing device, and spraying the desizing agent onto the grey cloth;

[0031] S2: Desizing the grey cloth by a desizing device; the desizing machine cleans the sizing agent, other additives and a certain mechanical force on the fiber surface to obtain a desized cloth;

[0032] S3: washing and fixing the desized textile fabric obtained by desizing and washing with a fixing agent three times on both sides;

[0033] S4: Dry the fabric in an oven under a certain tension to ensure the dimensional stability and flatness of the fabric;

[0035] The water washing temperature in S3 is 80° C. and the water washing time is 32 min.

[0036] In the step S4, the drying temperature is 170° C. and the setting time is 2 minutes.

[0037] A fabric woven by a fabric weaving process, the fabric is composed of the following raw materials in parts by weight: 50-60 parts of cashmere, 20-30 parts of camel hair, 20-30 parts of cotton fiber, 10-15 parts of polyester fiber and 3-5 parts of mildewproofing agent.

[0038] like Figure 3 , Figure 5 and Fig. 9 As shown:

[0039] The desizing device comprises a fixed frame 101, the upper end of the fixed frame 101 is fixedly connected to a double spray head 102, the lower end of the fixed frame 101 is symmetrically mounted with two filter plates 103, the outer ends of the two filter plates 103 are both rotatably connected to rollers 104, the two filter plates 103 are both fixedly connected to a stepping motor capable of driving the rollers 104 to rotate, a core shaft 201 is rotatably connected between the two filter plates 103 on the fixed frame 101, and two spiral scrapers 202 that are coiled around each other are mounted on the core shaft 201; the spiral scrapers 202 are made of stainless steel; both ends of the double spray head 102 are provided with water inlet pipes with control valves;

[0040] The head end of the grey cloth is introduced from the filter plate 103 and the roller 104 on the left, and then passes through the upper ends of the two spiral scrapers 202 and is led out from the filter plate 103 and the roller 104 on the right. The spiral scraper 202 slightly lifts the grey cloth upward, and the desizing agent is injected into the water inlet pipe on the left side of the double spray head 102, and the desizing agent is sprayed from the nozzle on the left side of the double spray head 102. Clean water is injected into the water inlet pipe on the right side of the double spray head 102, and the clean water is sprayed from the nozzle on the right side of the double spray head 102. The two nozzles on the double spray head 102 are respectively located at the upper ends of the two filter plates 103, so that the desizing agent can be evenly sprayed on the grey cloth above the filter plate 103 on the left, so that the grey cloth can be fully contacted and soaked with the desizing agent, and the clean water can be evenly sprayed on the grey cloth above the filter plate 103 on the right, so as to clean the desized grey cloth;

[0041] The core shaft 201 is controlled to rotate, and the core shaft 201 drives the two spiral scrapers 202 to rotate. The two spiral scrapers 202 are in contact with the bottom surface of the grey cloth, so that the two spiral scrapers 202 can scrape off the oil, impurities and sizing agent on the bottom surface of the grey cloth that has been fully in contact with the desizing agent when rotating, thereby improving the dyeing rate and uniformity of the fabric in the subsequent dyeing process;

[0042] The two rollers 104 rotate intermittently clockwise synchronously, driving the grey cloth to intermittently move to the right, so that different parts of the grey cloth can contact the two spiral scrapers 202. The two spiral scrapers 202 scrape off the oil, impurities and slurry from the bottom surface of the entire grey cloth. Storage boxes are placed at the lower ends of the two filter plates 103, so that the excess desizing agent and water for washing the grey cloth leak out from the two filter plates 103 after contacting the grey cloth and are collected in the corresponding storage boxes. When the roller 104 on the right rotates, it can roll the grey cloth to squeeze out the excess clean water on the grey cloth.

[0043] There are two spiral scrapers 202, which are arranged to be coiled around each other to improve the efficiency of scraping off the sizing agent on the grey cloth. Secondly, the mandrel 201 can be controlled to reciprocate in both positive and negative directions, thereby being able to more thoroughly scrape off the oil, impurities and sizing agent on the grey cloth, thereby improving the desizing effect of the grey cloth.

[0044] Furthermore, when the grey cloth is introduced, the grey cloth can be passed through the lower ends of the two spiral scrapers 202, so that when the two spiral scrapers 202 rotate, the oil, impurities and slurry on the top surface of the grey cloth can be scraped off, thereby improving the dyeing rate of the fabric in the subsequent dyeing process; therefore, the top or bottom surface of the grey cloth can be desized as needed.

[0045] like Figures 5 to 6 As shown:

[0046] A plurality of collars 204 are evenly and horizontally fixedly connected between the two spiral scrapers 202, a spring 205 is fixedly connected between two adjacent collars 204, the spring 205 is sleeved on the core shaft 201, and the two collars 204 at the outermost ends are respectively fixedly connected to the two groove wheels 203;

[0047] The groove wheel 203 is key-connected to the core shaft 201, so that when the core shaft 201 rotates, the two groove wheels 203 can be driven to rotate through the key, and then the two groove wheels 203 can drive the two spiral scrapers 202 to rotate to scrape the slurry on the grey cloth. Secondly, the two groove wheels 203 can also slide on the core shaft 201 along the axis direction of the core shaft 201. Since the spiral scraper 202 is made of stainless steel and can be bent and deformed, when the distance between the two groove wheels 203 becomes smaller, the two groove wheels 203 will squeeze the two spiral scrapers 202, so that the two spiral scrapers 20 2 is compressed, thereby changing the pitch of the two spiral scrapers 202, and the overall length of the two spiral scrapers 202 is reduced, so that the density of the two spiral scrapers 202 winding around each other becomes larger, thereby increasing the contact area between the two spiral scrapers 202 and the grey cloth, so that the sizing on the grey cloth can be scraped off more efficiently. This method is suitable for desizing of wear-resistant grey cloth or for desizing of grey cloth in a short time with high efficiency; therefore, the pitch of the two spiral scrapers 202 can be changed by changing the spacing between the two groove wheels 203, so as to desizing grey cloths of different materials;

[0048] The arrangement of multiple rings 204 and springs 205 enables the two spiral scrapers 202 to be limited when they are compressed, so that the two spiral scrapers 202 are regularly compressed and stretched and reset along the axial direction of the core shaft 201, thereby preventing the two spiral scrapers 202 from being eccentric to the axis of the core shaft 201 during compression and bending out of shape, thereby affecting the scraping of the grey cloth slurry.

[0049] like Figure 3 and Figure 7 As shown:

[0050] The device also includes a side frame 105, two side frames 105 are symmetrically mounted on the fixed frame 101, the core shaft 201 is rotatably connected between the two side frames 105 through a bearing, one of the side frames 105 is fixedly connected with a driving motor capable of driving the core shaft 201 to rotate, and the driving motor is started to drive the two spiral scrapers 202 on the core shaft 201 to rotate; the top beam 301 is slidably connected between the two side frames 105, and the left side of the top beam 301 is fixedly connected with a scraper I 304 through screws;

[0051] Scraper Ⅰ304 is located between the filter plate 103 and the spiral scraper 202 on the left. When the grey cloth passes through the position of the two spiral scrapers 202, the scraper Ⅰ304 is pressed on the top surface of the grey cloth, so that the grey cloth is slightly concave downward under the pressure of the scraper Ⅰ304, so that the pointed scraper on the scraper Ⅰ304 can scrape off the hard impurities agglomerated on the grey cloth during the feeding process of the grey cloth, and the scraped impurities remain on the inclined L-shaped scraper Ⅰ304. The scraper Ⅰ304 is provided with a filter groove, so the desizing agent is filtered out, and only the scraped hard impurities remain on the scraper Ⅰ304, thereby realizing the collection of impurities.

[0052] like Figure 6 As shown:

[0053] The first electric push rod is fixedly connected between the side frame 105 and the core shaft 201; the two ends of the top beam 301 are respectively hingedly connected to a hinged arm 302, and the two hinged arms 302 are both hingedly connected to a shift fork 303, and the two shift forks 303 are respectively inserted into the two groove wheels 203;

[0054] The first electric push rod is started to drive the top beam 301 to move up and down. The top beam 301 drives the forks 303 inserted on the two groove wheels 203 to slide away from each other or move towards each other through the two hinged arms 302, thereby driving the two groove wheels 203 to slide towards or away from each other, thereby changing the pitch of the two spiral scrapers 202 and the density of the two spiral scrapers 202, which is suitable for desizing of grey cloths of different materials.

[0055] like Figure 3 and Figure 7 As shown:

[0056] The other side of the top beam 301 is fixedly connected with a scraper II 305 by screws; the scraper II 305 is located between the filter plate 103 and the spiral scraper 202 on the right side. When the grey cloth is scraped by the two spiral scrapers 202 to remove the slurry, it passes through the lower end of the scraper II 305. The scraping blade of the scraper II 305 presses the grey cloth, so that the excess desizing agent on the grey cloth can be squeezed out, thereby facilitating the subsequent cleaning and coloring of the grey cloth.

[0057] Secondly, when the top beam 301 moves downward, it can simultaneously drive the scraper I 304 and the scraper II 305 to move downward. The downward movement of the scraper I 304 and the scraper II 305 can increase the pressure on the grey cloth, making the grey cloth deform to a greater extent, thereby being able to more thoroughly scrape off the impurities on the grey cloth and squeeze out the excess desizing agent on the grey cloth more thoroughly, thereby improving the subsequent cleaning effect on the grey cloth.

[0058] like Fig. 9 As shown:

[0059] The two side frames 105 are both slidably connected to the fixed frame 101, and the fixed frame 101 is fixedly connected to two second electric push rods that can push the side frames 105 to slide respectively;

[0060] When the cloth passes by the lower ends of the two spiral scrapers 202, the two second electric push rods start to drive the two side frames 105 to move downward, and the two side frames 105 drive the core shaft 201 and the two spiral scrapers 202 to move downward, so that the degree of downward deformation of the grey cloth driven by the two spiral scrapers 202 becomes greater, and the grey cloth is fully stretched, thereby increasing the contact force between the grey cloth and the two spiral scrapers 202, further improving the effect of the two spiral scrapers 202 on scraping off the sizing on the grey cloth, and being able to scrape off and desizing the grey cloth with impurities and stubborn sizing.

[0061] like Figure 8 As shown:

[0062] The device further includes a material box 206, both ends of which are slidably connected to the two side frames 105, and a third electric push rod is fixedly connected between the material box 206 and the side frames 105;

[0063] The desizing agent is injected into the material box 206. When the cloth passes through the lower ends of the two spiral scrapers 202, the third electric push rod is controlled to start and drive the material box 206 to move upward, so that the two spiral scrapers 202 enter the material box 206. At the same time, the grey cloth is pressed between the material box 206 and the two spiral scrapers 202, and the grey cloth is immersed in the desizing agent in the material box 206 again. When the two spiral scrapers 202 rotate, they cooperate with the curved bottom surface of the material box 206 to more thoroughly scrape off the impurities, slurry and dirt on the grey cloth, and the desizing effect is more thorough.

[0064] like Fig. 9 As shown:

[0065] The inner ends of the two filter plates 103 are rotatably connected to the fixed frame 101. The two filter plates 103 are provided with a slide groove 107. The two slide grooves 107 are slidably connected with a lever frame 106. The two lever frames 106 are symmetrically fixedly connected to the side frame 105 at the front end.

[0066] When the side frame 105 moves downward, it can drive the two lever frames 106 to move downward. The two lever frames 106 drive the two filter plates 103 to rotate downward by cooperating with the two slide grooves 107, so that both sides of the cloth are in an inclined state, and the inner end surfaces of the two filter plates 103 will contact the grey cloth, so that the grey cloth can be more fully stretched after multiple bendings, and at the same time, the blocky dirt condensed on the grey cloth can be fully cracked and scraped off when bending.

[0067] Further, such as Fig.10 As shown:

[0068] The inner ends of the two filter plates 103 are both bonded with scrapers 108 ; the scrapers 108 can improve the effect of separating hard dirt on the cloth when the cloth contacts the inner ends of the filter plates 103 .
