Description

Technical Field

[0001] The invention relates to the technical field of yarn textile, and more specifically to a surface treatment method for cotton textile yarn. Background Art

[0002] Cotton yarn is yarn spun from pure cotton fiber and is one of the common raw materials in textile manufacturing. The main raw material of cotton yarn is cotton fiber, usually long-staple cotton or short-staple cotton. Cotton fiber has the characteristics of good moisture absorption, good air permeability, comfort and softness, and is suitable for making various clothing and household items.

[0003] There are various surface treatment methods for cotton textile yarn, including physical methods, chemical methods, coating methods, etc., which aim to improve the functionality, durability and aesthetics of the yarn. These treatment methods can be used alone or in combination to meet specific application requirements. Physical methods include heat setting treatment, which improves the dimensional stability and mechanical strength of the yarn through high temperature treatment, and reduces deformation and wrinkles during washing or use; brushing treatment, which treats the surface of the yarn through physical brushing equipment to form a fluff layer on the surface to enhance softness and warmth; calendering treatment, which calenders the surface of the yarn through hot pressing rollers to give it better gloss and smoothness. Chemical methods include softening treatment, which uses softeners (such as silicones and fatty acids) to treat the yarn to increase its softness and comfort; shrink-proof treatment, which uses resins or special chemicals to treat the yarn to reduce its shrinkage rate during washing; waterproof and oil-proof treatment, which applies waterproof and oil-proof agents to make the yarn resistant to water and oil stains; antibacterial and deodorizing treatment, which gives the yarn antibacterial and deodorizing properties by adding antibacterial agents (such as silver ions, zinc ions, etc.). The coating methods include nano-coating, which applies nanotechnology coating to give the yarn additional functions, such as anti-UV, anti-static, enhanced wear resistance, etc.; functional coating, such as coating with conductive materials, makes the yarn conductive and suitable for smart textiles.

[0004] Most of the existing surface treatment methods for cotton textile yarn are carried out in an assembly line, step by step, which prolongs the treatment cycle and reduces the processing efficiency. However, brushing in physical methods and nano-coating in coating methods are time-consuming processes.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0023] Embodiment 1:

[0024] See also Figure 1-3 , a cotton yarn surface treatment method, comprising the following steps: S1. Pre-treating the cotton yarn to remove oil stains and dust and then placing the cotton yarn on an integrated device; S2, setting the brush hardness, speed and pressure parameters of the brushing machine in the integrated device; S3, selecting appropriate nanoparticles according to the required functions and preparing the coating solution, and filling it into the spraying equipment; S4, passing the cotton yarn through a brushing machine, allowing the mechanical brush to lightly touch the surface of the yarn, and repeating the process until a fluffy effect appears; S5, starting the spraying equipment after detecting the presence of fluff using an infrared laser detector; S6. While the brushing machine is reciprocating, spraying is performed in combination with a spraying device; S7. When the fluff effect of the cotton yarn is achieved and the spraying is completed, start the drying equipment to dry it.

[0025] The specific steps of preprocessing in step S1 are as follows: S101. Before cleaning, first visually inspect the cotton yarn to determine the extent and distribution of oil stains and dust; S102. Select the appropriate cleaning agent according to the type of oil stains and use a mild non-ionic surfactant; S103, soaking the cotton yarn in warm water containing a detergent, and washing the soaked cotton yarn using an appropriate washing device; S104. After cleaning, the yarn needs to be rinsed with plenty of clean water to remove all detergents and loose stains; S105, using a dehydrator to gently remove excess water at a low speed, and then laying the washed yarn flat or hanging it in a dryer for drying; S106, after drying, the yarn is checked again and softened to restore the softness and elasticity of the yarn.

[0026] In step S102, the mild nonionic surfactant is a combination of any one or more of alkydphenol polyoxyethylene ether, alcohol polyoxyethylene ether, fatty amide polyoxyethylene ether, polyoxyethylene ether, polysorbate, and sucrose ester; mild nonionic surfactants are used because they usually have low corrosiveness to fibers and can effectively remove oil stains and stains while maintaining the integrity and softness of the fibers.

[0027] In step S103, the warm water temperature is 30℃-40℃, and the soaking time is 0.5h-3h. In step S105, the drying temperature is 50℃-60℃, and the drying time is 0.5h-1h. Too long soaking time and too high water temperature, too high drying temperature and too long drying time may cause fiber damage.

[0028] The specific steps of the softening process in step S106 are as follows: S1061. Select appropriate softener according to the material and requirements of the yarn; S1062, heating the mixed softener solution to 30°C-40°C, and completely immersing the yarn in the softener solution for 30min-60min; S1063, gently stir during the soaking process, take out, rinse and finally dry, which is similar to step S105 in the pretreatment.

[0029] See also Figure 4-7 In step S1, the integrated device includes an integrated warehouse 1, a control groove 2 is opened on the upper inner wall of the integrated warehouse 1, an electric slide rail is installed in the control groove 2, a control slider 3 is slidably connected in the control groove 2, an electric telescopic rod 4 is fixedly connected at the lower end of the control slider 3, an integrated component 5 is fixedly connected at the lower end of the electric telescopic rod 4, a conveying component 7 is arranged on the lower inner wall of the integrated warehouse 1, a pair of infrared laser detectors 6 are fixedly connected at the inner end of the integrated warehouse 1, and the infrared laser detector 6 is located above the conveying component 7. The yarn is conveyed into the integrated warehouse 1 through the conveying component 7, and the electric telescopic rod 4 is controlled to lower the integrated component 5 to the surface of the yarn. Then, the control slider 3 is controlled by the electric slide rail to reciprocate in the control groove 2, so that the integrated component 5 repeatedly moves on the surface of the yarn until the infrared laser detector 6 detects that the fluff is standing up.

[0030] The integrated component 5 includes a brush plate 51, a soft brush 52 is fixedly connected to the lower end of the brush plate 51, a feed bin 53 is opened in the brush plate 51, and a plurality of spray ports 54 are arranged on the lower inner wall of the feed bin 53. A pair of storage boxes 8 are inlaid on the upper end of the integrated bin 1, and the storage box 8 is connected to the feed bin 53 through a long hose. The surface of the yarn is repeatedly rubbed and brushed by the soft brush 52. When the infrared laser detector 6 detects the erected fluff, the feed bin 53 is started to allow the soft brush 52 to coat the nanomaterial on the fluff and the yarn surface. At the same time, with the cooperation of the soft brush 52, the nanomaterial can be fully coated on the fluff and the outer surface of the yarn. Subsequently, the storage box 8 supplies material to the feed bin 53. Two storage boxes 8 are provided because the demand for nanomaterial coating is large, so as to meet the material supply.

[0031] The conveying assembly 7 includes a conveyor belt 71, which is arranged in the integrated warehouse 1. A pair of rollers 72 are provided in the middle of the conveyor belt 71, and the rollers 72 are rotatably connected to the inner end of the integrated warehouse 1. An exhaust fan 73 is provided in the middle of the pair of rollers 72, and the exhaust fan 73 is fixedly connected to the inner end of the integrated warehouse 1. A plurality of evenly distributed air holes 74 are opened at the upper end of the conveyor belt 71. The exhaust fan 73 is used for exhaust, so that the gas overflows from the air holes 74 to blow on the yarn, so that the fluff can stand up better, and the coated yarn and fluff can be air-dried at the same time.

[0032] It can be seen from the above technical solutions that the present invention has the following beneficial effects: The processing flow in this scheme significantly improves the efficiency and quality of cotton yarn processing. The initial pretreatment stage effectively removes oil stains and dust on the cotton yarn by using specific non-ionic surfactants and controlled washing conditions, while protecting the integrity and softness of the fiber; by setting appropriate brush hardness, speed and pressure, as well as synchronous spraying treatment, not only the uniformity of the fluff effect is guaranteed, but also the consistency of the treatment effect is ensured by real-time monitoring through infrared laser detectors. This integrated brushing and spraying treatment greatly shortens the processing time and simplifies the production process through integrated operation; the optimized drying and softening steps ensure the rapid drying of the yarn and good softness recovery. The efficiency of the entire process is not only reflected in the reduction of operating steps, but also in the energy and time savings, which greatly improves the overall production efficiency and can achieve higher production efficiency and lower costs while ensuring product quality.
