Description

Technical Field

[0001] The present invention belongs to the field of dishcloths, and specifically relates to a production process and application of a dishcloth that can be torn into pieces. Background Art

[0002] With the increasing attention of people to cleanliness, hygiene and health, the market demand for efficient, convenient and environmentally friendly cleaning fabrics is gradually increasing. Most traditional cleaning fabrics (such as dishcloths, wiping cloths, etc.) need to be washed frequently, and it is difficult to completely disinfect them after use, which is easy to breed bacteria and difficult to meet different cleaning needs. In addition, traditional fabrics often have difficulty in controlling the tearing strength and cleaning effect, making their use process less convenient or efficient.

[0003] Traditional cleaning fabrics usually use cotton cloth or chemical fiber as raw materials and are processed by ordinary weaving or knitting processes. However, these fabrics often cannot achieve efficient antibacterial, anti-fouling and waterproof functions during use, and it is often difficult to thoroughly disinfect them after washing, which is easy to cause cross-contamination. In addition, due to material limitations, traditional fabrics often cannot provide good tearability and controllability during the cleaning process, and users need to rely on washing and drying, which is both time-consuming and increases the use cost.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a production process and application of a dishcloth that can be torn into pieces, and solve the problems raised in the above background art.

[0006] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] A production process of a dishcloth that can be torn into pieces includes the following steps:

[0008] S1: Produce a knitted base fabric, use loop yarn and ground yarn for knitting, and at the same time adjust the height of the knitting sinker to 1.7 - 1.9 mm;

[0009] S2: During the knitting process, set staggered empty stitch traces on the base fabric, and these traces form hairless loop areas, which serve to divide the fabric into several sheet-like units;

[0010] S3: Perform dyeing, dehydration and drying treatments on the knitted fabric, and add additives for shaping;

[0011] S4: Through the raising process, pull out the fibers in the loop yarn from the fabric surface to form fluff particles;

[0012] S5: Use an ultrasonic cutting machine to cut the fabric along the empty stitch traces;

[0013] S6: Perform ultrasonic hot melt treatment on the cut cloth strips in the empty stitch area to form tear lines;

[0014] S7: Cut or roll the cloth strips to finally form a tearable dishcloth with tear lines, and the distance between the tear lines is 5 - 20 cm.

[0015] In this embodiment, in step S3, the composition of the auxiliary agent is: nano-silica: 0.5 - 2%, nano-silver: 0.1 - 0.5%, nano-copper: 0.5 - 1.5%, soft fluffing auxiliary agent (BS-04L): 1 - 3%, water repellent auxiliary agent (AM): 6 - 8%, and the balance is water.

[0016] In this embodiment, the steps for preparing the auxiliary agent are:

[0017] Mix the nano-silica solution, nano-silver solution, nano-copper solution, soft fluffing auxiliary agent solution and water repellent auxiliary agent solution in proportion;

[0018] Stir the mixed solution evenly, and use an ultrasonic treatment device for oscillation to ensure that the nano-particles are evenly dispersed. The ultrasonic frequency is 20 - 40 kHz, and the treatment time is 10 - 15 minutes;

[0019] Apply the obtained solution to the fabric surface, and use heat setting treatment to firmly fix the coating. The setting temperature is 140 - 160 °C, and the fabric speed is 16 - 20 YPM;

[0020] Wash and dry the set fabric to remove the residual auxiliary agent.

[0021] In this embodiment, in step S1, the terry yarn is 100D / 144F DTY, and the ground yarn is 100D / 96F DTY.

[0022] In this embodiment, in step S2, the width of the empty stitch is controlled between 1 - 2 mm.

[0023] In this embodiment, in step S4, two raising machines are used to process the front and back sides of the fabric respectively.

[0024] In this embodiment, in step S6, the width of the tear line is 0.5 - 1 mm.

[0025] In this embodiment, in step S7, the hot melt temperature is controlled at 100 - 150 °C.

[0026] Application of a tearable dishcloth prepared by the described preparation method in cleaning and disinfection.

[0027] After adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all the advantages described below:

[0028] By adding nano-silica and water-repellent aids (such as AM) during the preparation process, the dishcloth of the present invention has excellent waterproof and stain-resistant properties. Water droplets are not easily attached to the fabric surface, and stains are also difficult to penetrate, enabling the fabric to maintain a clean state for a longer time, greatly improving the service life and cleaning efficiency of the fabric. During the fabric preparation process, antibacterial components such as nano-silver and nano-copper are used, and these components can effectively inhibit the growth of bacteria and fungi on the fabric surface, reducing the risk of bacterial cross-contamination. The dishcloth treated with antibacterial treatment can effectively prevent the reproduction of bacteria on the fabric, ensuring the high efficiency of cleaning, and is especially suitable for occasions with high hygiene requirements such as medical treatment and food processing.

[0052] In step S2 of this embodiment, the width of the empty stitch line is controlled between 1 - 2 mm.

[0053] In step S4 of this embodiment, use two raising machines to process the front and back sides of the fabric respectively.

[0054] In step S6 of this embodiment, the width of the tear line is 0.5 - 1 mm.

[0055] In step S7 of this embodiment, the hot melt temperature is controlled at 100 - 150 °C.

[0056] Example 1: A production process of a tearable rag, comprising the following steps:

[0057] Step S1: In this embodiment, 100D / 144FDTY terry yarn and 100D / 96FDTY ground yarn are selected for knitting. By adjusting the height of the knitting sinker to 1.7 mm, the fabric has a moderate thickness and good looseness.

[0058] Step S2: During the knitting process, criss-crossed empty stitch lines are set on the fabric. These stitch lines form a terry-free area and divide the fabric into several sheet-like units. The width of the empty stitch lines is controlled at 1 mm.

[0059] Step S3: The knitted fabric is dyed, dewatered and dried, and then the following auxiliaries are added for setting: nano-silica: 0.5%, nano-silver: 0.1%, nano-copper: 0.5%, soft raising auxiliary (BS-04L): 1%, water-repellent auxiliary (AM): 6%, and the balance is water.

[0060] Step S4: Two raising machines are used to raise the front and back sides of the fabric respectively, pulling out the fibers in the terry yarn to form fluff particles.

[0062] Step S6: The cut fabric strips are ultrasonically hot melted in the area of the empty stitch lines to form a tear line, and the width of the tear line is 0.5 mm.

[0063] Step S7: The fabric strips are cut or wound, and finally a tearable rag with a tear line is formed. The spacing of the tear lines is 10 cm.

[0064] Example 2: A production process of a tearable rag, comprising the following steps:

[0065] Step S1: In this embodiment, 100D / 144FDTY terry yarn and 100D / 96FDTY ground yarn are used. By adjusting the height of the knitting sinker to 1.9 mm, an ideal fabric thickness and moderate hair density are obtained.

[0066] Step S2: During the knitting process, criss-crossed empty stitch lines with a width of 1.5 mm are set to divide the fabric into several sheet-like units.

[0067] Step S3: Dye, dehydrate, and dry the fabric, and then add the following auxiliaries for setting: nano-silica: 2%, nano-silver: 0.3%, nano-copper: 1%, soft fluffing auxiliary (BS-04L): 2%, water-repellent auxiliary (AM): 7%, and the balance is water.

[0068] Step S4: Use two raising machines to process the front and back sides of the fabric respectively to ensure sufficient pulling out of the fibers and form ideal fluff particles.

[0069] Step S5: Use an ultrasonic cutting machine to cut the fabric along the empty stitch line to ensure that the cutting edge is neat and the loops are not loose.

[0070] Step S6: Conduct ultrasonic hot-melt treatment on the cut fabric strips, and the width of the tear line is 1 mm.

[0071] Step S7: Cut the fabric strips into the required sizes or wind them into rolls, and finally form a tearable dishcloth with tear lines. The spacing of the tear lines is 15 cm.

[0072] Example 3: A production process for a tearable dishcloth in sheets, comprising the following steps:

[0073] Step S1: In this example, 100D / 144F DTY loop yarn and 100D / 96F DTY ground yarn are selected, and the height of the knitting sinker is adjusted to 1.8 mm to ensure that the fabric reaches the ideal thickness and hair density.

[0074] Step S2: During the knitting process, set staggered empty stitch lines with a width controlled at 1.2 mm to ensure that the fabric is divided into several sheet-like units.

[0075] Step S3: Dye, dehydrate, and dry the fabric, and then use the following auxiliaries for setting: nano-silica: 1%, nano-silver: 0.2%, nano-copper: 0.8%, soft fluffing auxiliary (BS-04L): 1.5%, water-repellent auxiliary (AM): 6.5%, and the balance is water.

[0076] Step S4: Use two raising machines to process the front and back sides of the fabric respectively to pull out the fibers and form fluff particles.

[0077] Step S5: Use an ultrasonic cutting machine to cut the fabric along the empty stitch line to ensure that the cut fabric has a neat edge and firm loops.

[0078] Step S6: Conduct ultrasonic hot-melt treatment in the area of the empty stitch line, and the width of the tear line is 0.8 mm.

[0079] Step S7: Cut or wind the fabric strips to finally form a tearable dishcloth with tear lines. The spacing of the tear lines is 12 cm.

[0080] Hair density: Hair density refers to the number of loops per unit area. Use a standard loop density meter or observe the fabric surface through a microscope to calculate the number of loops per square meter. This data represents the density of loops on the fabric surface:

[0081] Water contact angle: Use a water droplet contact angle tester to drop water droplets on the fabric surface and measure the contact angle between the water droplets and the fabric surface. The larger the contact angle, the stronger the hydrophobicity of the fabric. The standard superhydrophobic water contact angle should be greater than 90°, and its expression is: θ = water contact angle, γ SV = solid-vapor interfacial tension, γ SL = solid-liquid interfacial tension, γ LV = liquid-vapor interfacial tension.

[0082] Tear strength: Use a standard tear strength testing machine to measure the maximum tensile force when the fabric is stressed along the tear line. This test ensures that the fabric is not easily torn during use: where F = maximum tensile force (Newton), A = width of the tear line (square meter).

[0083] Antibacterial property (bacteriostatic rate): Adopt a standard antibacterial test method (such as ISO 20645), contact the fabric with Escherichia coli and Staphylococcus aureus, and after a certain period of time, calculate the bacteriostatic rate by culturing and observing the bacteriostatic effect

[0084]

[0085]

[0086] In the experiment, silver nanoparticles and copper nanoparticles are the main antibacterial components, and the difference in their concentrations directly affects the antibacterial performance of the fabric. The higher the concentrations of silver nanoparticles and copper nanoparticles, the stronger the antibacterial effect usually is. In Example 2, the concentration of silver nanoparticles is 0.3% and the concentration of copper nanoparticles is 1%, which makes the bacteriostatic rate of the fabric the highest. High concentrations of silver nanoparticles and copper nanoparticles not only improve their respective antibacterial abilities but also can produce a synergistic effect, that is, the two act together to produce a stronger antibacterial barrier, significantly enhancing the bacteriostatic ability of the fabric.

[0087] As a self-cleaning coating, nano-silica mainly serves to improve the superhydrophobicity and stain resistance of fabrics, preventing water and stains from penetrating or adhering. Although nano-silica itself has no antibacterial property, its presence can enhance the antibacterial protective layer of the fabric, indirectly improving the antibacterial property of the fabric. In Example 2, the concentration of nano-silica is relatively high (2%), and its surface protective layer is stronger, making it more difficult for bacteria to adhere, thus contributing to the improvement of antibacterial performance. The higher concentration of nano-silica improves the surface state of the fabric, reduces the adhesion of stains, and helps to enhance the antibacterial effect of the fabric.

[0088] The function of the softening and raising agent is to improve the softness of the fabric and enhance the formation of plush particles. A higher concentration of the softening and raising agent not only improves the hand feeling of the fabric but also increases the contact area between the fabric surface and the antibacterial agent, helping to enhance the effect of the antibacterial component. The 2% concentration in Example 2 may improve the distribution of the antibacterial agent in the fabric, further enhancing the antibacterial effect of the fabric.

[0089] The water repellent agent can provide good hydrophobicity for the fabric, preventing moisture and bacteria from penetrating into the interior of the fabric. Moisture is an important factor for bacterial growth, and higher hydrophobicity helps to prevent the contact between moisture and bacteria, thus improving antibacterial performance. The 7% in Example 2 reflects a relatively high water repellency, enhancing the waterproof effect of the fabric and also indirectly helping to improve antibacterial performance by preventing bacteria from multiplying due to moisture penetration.

[0090] The present invention is not limited to the above embodiments. Anyone should know that structural changes made under the inspiration of the present invention, as long as they have the same or similar technical solutions as the present invention, fall within the protection scope of the present invention. The technologies, shapes, and structures not described in detail in the present invention are all well-known technologies.
