Description

Technical Field

[0001] This utility model relates to a fleece fabric, specifically an antibacterial fleece fabric. Background Technology

[0002] Fleece fabric is woven on a circular knitting machine. After weaving, the greige fabric undergoes a series of complex processing steps, including dyeing, napping, combing, shearing, and fleece re-tightening. The front side has a dense, fluffy nap that is resistant to shedding and pilling, while the reverse side has a sparse, even nap, resulting in excellent fluffiness, elasticity, and a soft feel. It traps a large amount of air, slowing down convection with the outside air, and possesses excellent warmth retention properties. It is a popular fleece product in the outdoor market and is commonly used in the production of winter clothing and home textiles.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] Combination Figure 1This embodiment provides a detailed description of an antibacterial fleece fabric, comprising: a fabric body, the fabric body including a fleece surface and a thermal surface; the fleece surface is woven from yarns of the 1st, 2nd, 4th, and 5th layers, and the thermal surface is woven from yarns of the 3rd and 6th layers; antibacterial yarns are inserted into the 1st, 2nd, 4th, and 5th layers, and thermal yarns are inserted into the 3rd and 6th layers; the fabric body is woven from upper rotary knitting needles, lower cylinder knitting needles, and a triangular arrangement.

[0026] In the 3F, the upper needle plate B floats the thread, the upper needle plate A floats the thread, the lower syringe A forms a loop, and the lower syringe B forms a loop;

[0027] In the 4F section, the upper needle plate B is tucked in, the upper needle plate A is looped, the lower needle cylinder A is looped, and the lower needle cylinder B is tucked in.

[0028] In 5F, the upper needle plate B forms a circle, the upper needle plate A has a floating thread, the lower syringe A has a floating thread, and the lower syringe B has a floating thread.

[0029] In step 6F, the upper needle plate B and the upper needle plate A are threaded together, while the lower needle cylinder A and the lower needle cylinder B form loops.

[0030] Furthermore, the coil length of the 1st and 4th coils is 28.5cm / 100 coils, the coil length of the 2nd and 5th coils is 20.5cm / 100 coils, and the coil length of the 3rd and 6th coils is 31.0cm / 100 coils.

[0031] Furthermore, the antibacterial yarn is a chitosan-based silver-loaded antibacterial polyester yarn. Chitosan-based silver-loaded antibacterial polyester yarn is a polyester yarn with a chitosan-based silver-loaded antibacterial coating on its surface.

[0032] The chitosan-based silver-loaded antibacterial coating solution consists of nano-silver particles (antibacterial agent), chitosan (drug-release carrier), and acetic acid solvent. The preparation process is as follows: a certain mass of chitosan is weighed and added to a 2% acetic acid solution, and magnetically stirred for approximately 24 hours. After the chitosan is completely dissolved, a certain amount of silver nitrate is added, and the mixture is magnetically stirred for approximately 30 minutes under light-protected conditions until the drug is completely dissolved and uniformly dispersed. Then, a certain amount of the above solution is irradiated with ultraviolet light for a certain period to obtain the chitosan-based silver-loaded antibacterial coating solution. When the chitosan content is 2%, the coating consists of two layers, and the silver nitrate content is 0.8%, the diameter of the inhibition zone against Staphylococcus aureus and Escherichia coli is significantly increased, exhibiting a good antibacterial effect and significantly improving the antibacterial performance of polyester yarn.

[0033] Furthermore, the insulating yarn is an antibacterial and insulating core-spun and wrapped composite yarn. This antibacterial and insulating core-spun and wrapped composite yarn consists of a yarn core, outer short fibers, and outer filaments. The yarn surface is covered with regularly spaced filaments, making the yarn less prone to disintegration and slippage, thus improving abrasion resistance. The yarn core is a 44.4 dtex / 24F antibacterial polyester filament, the outer short fibers are Anteibe / Warm Fleece (blended in a 50 / 50 ratio), and the wrapping yarn is a 77.8 dtex / 36F graphene filament. Anteibe is a modified viscose fiber with antibacterial properties; Warm Fleece is a modified polyester with moisture-wicking, heat-retaining, and microcirculation-improving characteristics, offering good antibacterial and skin-protecting effects; and the graphene filament is an antibacterial, far-infrared, and UV-protective composite filament, using graphene modification technology to reduce far-infrared loss and maximize temperature rise, providing heat retention and warmth.

[0034] Example 2

[0035] The difference from Example 1 is that the antibacterial yarn is a colored, low-melting-point, core-sheath type antibacterial polyester fiber filament. The preparation process of the colored, low-melting-point, core-sheath type antibacterial polyester fiber includes: antibacterial agent preparation: 3 kg KGM, 0.25 kg nano-silver wire, 15 kg bamboo charcoal powder, and 90 kg water are mixed and vigorously stirred for 20 minutes at a stirring speed of 11000 r / min, allowed to stand for 30 hours, filtered, and dried at 90°C to constant weight to obtain the antibacterial agent; sheath material preparation: 100 kg of low-melting-point polyester chips are vacuum dried for 4 hours at a drying temperature of 60°C and a vacuum degree of -0.16 MPa, then 2.5 kg of color masterbatch and 2.5 kg of antibacterial agent are added and high-pressure ground for 16 minutes at a grinding pressure of 0.3 MPa and a grinding speed of 3000 r / min to obtain the sheath material; core material preparation: 100 kg of ordinary polyester, 2 kg HPMA, and 1.5 kg of antioxidant TNP are mixed evenly to obtain the core material. Two kg of sheath material and 10 kg of core material were fed into a composite spinning assembly for spinning at 180℃. After cooling and solidification, nascent filament fibers were obtained. These fibers were then oiled and wound using a winding machine, followed by secondary heating and stretching at 145℃ and a stretch ratio of 5.4 to produce colored, low-melting-point sheath-core type antibacterial polyester fiber. This colored, low-melting-point sheath-core type antibacterial polyester fiber exhibited an antibacterial rate of 99.8% against Staphylococcus aureus and 97.9% against Streptococcus albus. After 20 washes at 40℃, the antibacterial performance retention rate was 95%, demonstrating excellent antibacterial effect.

[0036] Example 3

[0037] Based on the above embodiments, a ceramic silver film is attached to the surface of the granular surface. Specifically, ceramic powder and silver powder are first added to PU resin in a certain proportion. The PU resin containing ceramic silver powder forms a ceramic silver film on the surface of the OPP film. Then, it is imprinted onto the base fabric using an OPP transfer mold, and the ceramic silver film is transferred to the surface of the granular surface using a hot stamping process. Adding ceramic powder to the PU resin allows the far-infrared rays emitted by the ceramic powder to be absorbed by the human body, accelerating blood circulation and giving the fabric multiple functions such as electromagnetic radiation protection, UV protection, and antibacterial properties. A small amount of silver powder is also added when adding the ceramic powder; silver powder has excellent reflective properties, giving the fabric a good warmth retention effect.
