Description

Technical Field

[0001] The invention relates to the technical field of textile production and processing, and in particular to a quick-acting wet-dry textile production process. Background Art

[0002] Fabrics are the core materials of products such as clothing and home textiles. They come in many types and have different characteristics, which determine the comfort, durability and appearance of the products. Fabrics can be classified according to different dimensions such as material, textile process, and organizational structure. For example, cotton cloth is popular for its breathability and moisture absorption, and is suitable for making casual wear and underwear. Silk is known for its lightness, softness and luster, and is suitable for making high-end women's clothing. Wool is used to make suits and coats for its warmth and formality. Leather is often used to make fashion and winter clothes because of its unique texture and warmth. Chemical fiber fabrics are brightly colored and soft, but their wear resistance, heat resistance and breathability are relatively poor. Blended fabrics combine the advantages of natural fibers and chemical fibers, which are both economical and practical. Each fabric has its specific application scenario and cultural background. Understanding the characteristics of fabrics is crucial for clothing design and production.

[0003] When current textile fabrics encounter moisture, whether it is splashing on the outer layer or absorbing sweat on the inner layer, once the moisture is absorbed, the fabric will stick to the skin due to the surface tension of water molecules, causing damp discomfort and poor breathability. This feeling of sticking to the skin and the lack of breathability will significantly reduce the wearing experience. Even a slight amount of moisture will greatly reduce the comfort and functionality of the clothing, resulting in a sharp decline in the user's overall experience.

[0004] Therefore, a quick-acting wet-dry textile production process is proposed to solve or alleviate the above problems. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] A quick-acting wet-dry textile production process comprises the following steps:

[0048] Step 1, mixing, completing the mixing of the viscose fiber raw material and the hot melt raw material through a mixer, hot melt raw material such as polyethylene, to avoid uneven heating of the two raw materials and the uneven texture of the final output fiber, thereby ensuring product quality.

[0049] Step 2, such as Figure 3-5As shown, the viscose fiber raw material is put into the wet spinning machine 2, and the wet spinning machine 2 includes a condensation tank 21 and a wet spinning plate 214. A partition 211 is fixedly connected in the condensation tank 21, and the partition 211 divides the inside of the condensation tank 21 into a storage chamber 212 and a liquid chamber 213. The wet spinning plate 214 is arranged in the storage chamber 212, and its outlet hole 2142 is arranged toward the liquid chamber 213. A hot spinneret 32 ​​connected to the extruder 3 through a connecting pipe 31 is arranged in the liquid chamber 213, and the hot spinneret 32 ​​is higher than the liquid level in the condensation tank 21. The viscose fiber raw material is processed according to the wet spinning method, which is a conventional technical means, so it is not repeated. The hot melt raw material is put into the extruder 3, and the hot melt raw material moves in the extruder 3 following the guidance of the screw in the extruder 3, and melts during the movement, so as to prepare for the subsequent spinning work.

[0050] Step 3: Before the viscose fiber raw material leaves the wet spinneret 214, it passes through the hole pressing assembly to form concave holes on the surface, and enters the coagulation tank 21 to form primary fibers, wherein Figure 12-15 As shown, the wet spinneret 214 includes a wet spinneret 2141 with an outlet hole 2142 and a pressure hole assembly fixedly connected to the outside thereof, the pressure hole assembly includes a limiting cover 2143 with an annular shape and an open inner peripheral wall, an annular airbag 2148 fixedly connected in the limiting sleeve, a connecting pipe 2144 connected to the annular airbag 2148 and passing through the limiting sleeve to the outside, a main pipe 2145 connecting a plurality of connecting pipes 2144, and an air pump connected to the main pipe 2145 through an air pipe, the air pump controls the increase or decrease of the gas volume in the annular airbag 2148, the limiting cover 2143 is fixedly connected to the outside of the wet spinneret 2141, and a plurality of through holes 2146 connected to the outlet hole 2142 are opened on the outer peripheral wall of the wet spinneret 2141, and a pin 2147 fixedly connected to the annular airbag 2148 is slidably connected in the through hole 2146, and the pressure hole assembly is in the process of entering. During processing, only the air pump is needed to inhale and exhaust air to control the forward and reverse flow of air. The air enters and exits the annular airbag 2148 in the order of the air pipe, the main pipe 2145 and the connecting pipe 2144. When the amount of air in the annular airbag 2148 increases, the annular airbag 2148 expands. Under the limiting effect of the limit cover 2143, the inner diameter of the annular airbag 2148 becomes smaller. The annular airbag 2148 pushes the pin 2147 to slide in the through hole 2146. The pin 2147 is inserted into the outlet hole 2142 of the wet spinneret 2141 and inserted into the unsolidified raw material. After leaving the wet spinneret 2141, the raw material enters the liquid chamber 213. When the raw material encounters the condensing liquid in the liquid chamber 213, it condenses to form primary fibers, thereby forming primary fibers with a plurality of concave holes on the outer peripheral wall.

[0051] Step 4, a first guide roller 215 and a second guide roller 216 located between the wet spinneret 2141 and the hot spinneret 32 ​​are provided in the liquid chamber 213, the first guide roller 215 and the second guide roller 216 are both rotatably connected in the liquid chamber 213, the first guide roller 215 is located between the second guide roller 216 and the wet spinneret, the horizontal height of the second guide roller 216 is greater than the horizontal height of the first guide roller 215 and it is located between the connecting head 321 and the hot spinneret 323, the first guide roller 215 and the second guide roller 216 are used to guide the spun fibers so that the spun fibers can be fully coagulated in the liquid chamber 213, and finally guided by the second guide roller 216 so that the spun fibers pass through the hot spinneret 32 ​​located in the coagulation tank 21 as the main fibers 11.

[0052] like Figure 6-11 As shown, the hot spinneret 32 ​​includes a connector 321 and a hot spinneret 323 which are connected to the extruder 3 through a connecting tube 31. The end of the connector 321 away from the connecting tube 31 is provided with a plurality of micro-ports connected to the inside thereof. The hot spinneret 323 is provided with an inlet hole 3231 penetrating along the thickness direction thereof, and a branch groove 3233 connected to the inlet hole 3231 is provided on the side facing the connector 321. The branch groove 3233 is connected to the micro-ports through a branch tube 322. The side of the hot spinneret 323 away from the connector 321 is provided with an outlet hole 3232 connected to the inlet hole 3231 and the branch groove 3233. The extruder 3 extrude the hot melt raw material to the hot spinneret 32 Auxiliary fibers 12 are partially embedded in the concave hole, and a plurality of auxiliary fibers 12 are distributed in an annular array on the outside of the main fiber 11 to form a quick-drying fiber 1. The main line first enters the inlet hole 3231 manually and leaves from the outlet hole 3232. Then, the hot-melt raw material is extruded by the extruder 3 and enters the connector 321 through the connecting pipe 31. The micro-opening in the connector 321 allows the hot-melt raw material in a molten state to enter the branch groove 3233 of the hot spinneret 323 through the branch pipe 322, and enter the connection with the inlet hole 3231 under the guidance of the branch groove 3233, and under the shape restriction of the outlet hole 3232, as shown in FIG. Figure 1 and 2 As shown, the formed auxiliary fiber 12 can be partially embedded in the concave hole of the main fiber 11, and a plurality of auxiliary fibers 12 are distributed in a ring array on the outside of the main fiber 11 to form a quick-drying fiber 1, so that the desired fiber can be formed when leaving the exit hole 3232, and the fiber can be cooled in the liquid chamber 213, and a third guide roller 217 is rotatably connected in the liquid chamber 213, and the horizontal height of the third guide roller 217 is lower than the horizontal height of the hot spinneret 323, and under the guiding action of the third guide roller 217, the fiber is fully immersed in the liquid chamber 213 before leaving.

[0053] Step 5, rolling up into a roll, so that people can obtain the quick-drying fiber 1 in a roll shape.

[0054] Step 6, after unwinding and enzymatic hydrolysis, the exposed part of the main fiber 11 is reacted to form a number of pits 13. Since the material of the main fiber 11 is viscose fiber, the exposed part of the main fiber 11 can react to form a number of pits 13 during the enzymatic hydrolysis, and the pits 13 can increase the contact area of ​​the main fiber 11, making it easier to dissipate moisture. The quick-drying fiber 1 finally obtained, since the auxiliary fiber 12 on its outer wall does not have a good water absorption effect, can maintain a dry state to contact the human body surface, and since there is a certain distance between the main fiber 11 and the human body surface, the main fiber 11 will absorb water through the surface adsorption force of water, thereby removing moisture from the human body surface, so that people's body surface remains dry, and the main fiber 11 will not contact the human body, so that people remain dry and comfortable. Secondly, since the surface area of ​​the main fiber 11 is increased, it is easier to dissipate moisture and can dry faster.

[0055] Step 7, washing, drying and rolling the quick-drying fiber 1 after enzymatic hydrolysis. Washing can dissolve the dust and other solidified impurities remaining on the surface of the quick-drying fiber 1, so that the quick-drying fiber 1 can be kept in a relatively clean and tidy state for subsequent production.

[0056] In step 8, the quick-drying fiber 1 is put on a machine for weaving, either by machine or shuttle weaving, to form a textile. When the textile comes into contact with the human body, it mainly comes into contact with the auxiliary fiber 12, and the main fiber 11 has an effective effect of absorbing water and dissipating moisture, so that people can have a better user experience and are less likely to feel uncomfortable due to moisture.

[0057] Through the above steps, people can obtain fast-acting wet-dry textiles, and when the textile comes into contact with the human body, it can come into contact through the auxiliary fibers 12. Since the auxiliary fibers 12 are not hydrophilic and the main fibers 11 are hydrophilic, the surface adsorption force of water can make it be absorbed by the main fibers 11, and the pits 13 are used to increase the contact area of ​​the main fibers 11, so that the water dries quickly. The preparation process is relatively simple and can be produced by the entire machine without people having to do too much labor.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
