Description

Technical Field

[0001] This invention relates to a processing method for an eco-functional microfiber napped fabric, belonging to the field of fabric processing and preparation technology. Background Technology

[0002] Consumers are increasingly demanding personalized, multifunctional, and eco-friendly processing options for home textiles. Pile fabrics, widely used in kitchen cloths and automotive interiors, are now subject to higher requirements in terms of material selection and eco-friendly processing to meet consumer needs for comfort and functionality, as well as aesthetic appeal through patterns and designs. Conventional pile products primarily use polyester and nylon as raw materials, which have few polar groups in their structure, low moisture absorption, and are prone to static electricity during use. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides a processing method for eco-functional microfiber napped fabric, thereby solving the aforementioned technical problems.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a processing method for an eco-functional microfiber napped fabric, comprising the following steps:

[0005] Step 1: Material preparation: The raw materials are polyester yarn and nylon yarn;

[0006] Step 2: Polyester / Nylon Fabric Weaving: Polyester / Nylon Blended Fabric: Weaving is done by interlacing ultra-fine polyester yarn as warp yarn and ultra-fine nylon yarn as weft yarn;

[0007] Step 3: Use polyester / nylon blended fabric for one-bath dyeing with disperse dyes / acid dyes, and add anti-precipitation dispersant, carrier and acid release agent to achieve one-bath dyeing of polyester / nylon blended fabric;

[0008] Step 4: Plasma treatment of polyester / nylon blended fabric. Using polydimethylsiloxane (PDMS) as a low surface energy monomer, PDMS is hydrophilically modified by plasma and dispersed in an aqueous system to prepare PDMS emulsion. Then, waterborne polyurethane (WPU) is mixed to obtain PDMS-PU composite emulsion. The polyester / nylon blended matrix is ​​first etched by plasma, impregnated with PDMS emulsion and dried. The polyester / nylon blended fabric is treated with plasma again to induce PDMS-PU crosslinking on its surface to form a film. Finally, high-temperature baking is performed to induce wrinkling of the PDMS-PU film to form a micro-nano wrinkled structure.

[0009] Step 5: Use a loop-cutting machine for weaving, with a weaving density of 32-35 mesh and a total pile length of 30-40 mm. During weaving, the pile loops are directly cut to form pile, with a pile height of 8-10 mm. The greige fabric is cut into a cylindrical shape and is not split.

[0010] Furthermore, the dyeing process in step three is as follows: liquor ratio 1:10, add polyester-nylon blended fabric, dye at room temperature -30℃, heating rate is 2-4℃ / min, dye at 98-130℃ for 30-60 minutes, cool to 80℃ and remove from the vat, then wash with cold water and dry.

[0011] Furthermore, in step one, the material can be a combination of polyester and nylon fibers.

[0012] Furthermore, in step three, the disperse dye / acid dye accounts for 1%, 2%, 3%, or 4% of the fabric weight.

[0013] The beneficial effects of this invention are as follows: By selecting polyester and nylon as fiber materials and weaving them with different component ratios, and then dyeing them in the same bath using disperse dyes and acid dyes, the dyed fabric is subjected to plasma treatment to improve its hydrophobic properties, thereby obtaining a plush fabric with personalized, comfortable, safe, and functional properties. It can be widely used in kitchen cloths and automotive interiors, meeting consumers' needs in terms of ecological safety, comfort, and functionality. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the scope of the invention.

[0017] Step 1, Material preparation: Weave polyester microfiber and nylon microfiber into fabric in a 2:1 ratio.

[0018] Step 2: The dye concentration is 3%, the carrier DM-2308, the anti-precipitation dispersant DM-2480, and the acid release agent 2721 are used at a dosage of 0.5g / L. The liquor ratio is 1:10. Add the polyester-nylon blended fabric, put it into the dyeing vat at 30℃, the heating rate is 2℃ / min, raise it to 98℃ and dye for 45min, lower it to 80℃ and take it out of the vat, then wash it with cold water and dry it.

[0019] Step 3: Plasma treatment of polyester / nylon blended fabric

[0020] 5 g of PDMS was weighed and added to 500 ml of deionized water. The mixture was ultrasonically dispersed at 600 W and 40 kHz for 3 h to prepare a 10 g / L PDMS emulsion. WPU was added to the PDMS emulsion, controlling the PDMS:PU mass ratio to be 50:1. Ultrasonic dispersion was continued for 30 min to obtain PDMS-PU composite emulsions with different ratios. Polyester / nylon dyed fabrics were immersed in the PDMS-PU composite emulsions and ultrasonicated at 40 kHz for 10 min to ensure uniform adhesion of PDMS-PU to the polyester fabric. After removing the samples, they were dried at 60 °C for 30 min. The polyester / nylon dyed fabrics were then treated with plasma again to induce PDMS-PU crosslinking and film formation on their surface. Finally, they were baked at 130 °C for 10 min to prepare a superhydrophobic polyester / nylon blended microfiber fabric.
