A nanometer self-cleaning cashmere sweater fabric

Abstract

This utility model discloses a nano-self-cleaning cashmere sweater fabric, comprising a cashmere fabric layer, a nano-level antibacterial film layer, and a nano-level protective film layer. The nano-level antibacterial film layer is generated by sputtering on the surface of the cashmere fabric layer using vacuum deposition technology, and silver or zinc oxide is used. The nano-level protective film layer is titanium dioxide. The nano-self-cleaning cashmere sweater fabric of this utility model improves the wearing comfort of the cashmere sweater by using a cashmere fabric layer. Furthermore, the nano-level antibacterial layer formed by vacuum deposition technology is thin and composed of particles with gaps between them, allowing gaseous water molecules to pass through, which improves the waterproof and self-cleaning effects, and also enhances the breathability of the fabric.

Description

Technical Field

[0001] This utility model relates to a nano self-cleaning cashmere sweater fabric, which belongs to the category of wool sweater fabrics. Background Technology

[0002] Self-cleaning surfaces are those where dust and dirt can be removed or degraded by natural forces such as wind, rain, and gravity. As is well known, the surface of a lotus leaf possesses physical self-cleaning properties due to its superhydrophobicity, allowing it to remove dust. This physical self-cleaning characteristic enables materials such as glass, textiles, wood, plastics, and buildings to resist pollution from water, bacteria, and dirt. This not only saves maintenance time and costs but also reduces the use of water and chemicals, thus contributing to the protection of ecosystems.

[0003] Cashmere sweaters are made from cashmere knitted fabric. If the outer surface of the cashmere sweater fabric has a self-cleaning function, it will reduce the number of times the cashmere sweater needs to be washed, thus extending its lifespan. Therefore, how to develop a fabric for producing self-cleaning cashmere sweaters has become a problem to be solved. Utility Model Content

[0004] The purpose of this invention is to provide a nano self-cleaning cashmere sweater fabric that enables the surface of the fabric to have a good self-cleaning effect.

[0007] The nanoscale antibacterial film layer is generated by sputtering on the surface of the cashmere fabric layer using vacuum deposition technology, and silver or zinc oxide is used.

[0008] The nanoscale protective film is titanium dioxide.

[0015] Figure 2 This is a schematic diagram of the structure of the nano self-cleaning cashmere sweater fabric involved in Example 3.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] Combination Figure 1 This embodiment will be described in detail below. The present invention relates to a nano self-cleaning cashmere sweater fabric, comprising a cashmere fabric layer 1, a nano-level antibacterial film layer 2, and a nano-level protective film layer 3.

[0020] The nanoscale antibacterial film layer 2 is generated by sputtering on the surface of the cashmere fabric layer 1 using vacuum deposition technology, employing either silver or zinc oxide. The nanoscale protective film layer 3 is titanium dioxide. The nanoscale protective film layer 3 is also formed using vacuum deposition technology. Both the nanoscale antibacterial film layer 2 and the nanoscale protective film layer 3 are composed of nanoscale particles, possessing a waterproof effect, with a mechanism similar to the structure of a lotus leaf. Furthermore, the gaps between the nanoscale particles allow gaseous water molecules to pass through smoothly, thus enabling the cashmere fabric layer 1 to be both waterproof and breathable. The nanoparticles also give the cashmere fabric a self-cleaning effect. The surface of the cashmere fabric layer 1 itself has a water repellency rating of 0, completely lacking anti-stickiness properties. However, the cashmere fabric with the nanoscale antibacterial film layer 2 and the nanoscale protective film layer 3 achieves a surface waterproof rating of 4-5, exhibiting excellent anti-stickiness properties. Furthermore, the hydrostatic pressure resistance of the cashmere fabric layer 1 increased from 0 kPa to 2.5 kPa, exhibiting improved moisture-wicking properties. Its air permeability decreased by 2.1% in tests.

[0021] In this embodiment, the nanoscale antibacterial film layer 2 is made of zinc oxide, which has excellent antibacterial effects. A nanoscale protective film layer 3, made of titanium dioxide, is then applied to the nanoscale antibacterial film layer 2. Furthermore, the spacing between adjacent nanoscale titanium dioxide particles is greater than the spacing between adjacent nanoscale zinc oxide ions. This not only provides protection and delays the release of nanoscale zinc oxide, extending the antibacterial function of the fabric, but also provides UV protection.

[0022] Furthermore, the yarn used in the cashmere fabric layer 1 includes twisted cashmere yarn and Watos filaments. Watos is a new type of textile material developed by incorporating micro-powders of traditional Chinese medicine with natural antibacterial properties into polyester spinning solution, possessing antibacterial, deodorizing, moisture-absorbing, antistatic, and UV-protective functions. The cashmere yarn has a fineness of 60 count, the Watos filament has a fineness of 50D / 36F, and the prepared cashmere fabric layer has a weight of 150 grams per square meter.

[0023] The antibacterial effect test of the nano self-cleaning cashmere sweater fabric prepared in this embodiment showed that the inhibition rate against Escherichia coli and Staphylococcus aureus was greater than 99%.

[0024] Example 2

[0025] The nano self-cleaning cashmere sweater fabric involved in this embodiment differs from that in Embodiment 1 in that: the cashmere fabric layer 1 is a double-knitted fabric, one side is woven from cashmere yarn and the other side is woven from Hua Tuo silk filaments, and the Hua Tuo silk filament side is close to the nano-level antibacterial film layer 2.

[0026] Example 3

[0027] Combination Figure 2 This embodiment will be described in detail below. The difference between this embodiment and Embodiment 1 is that a moisture-absorbing and heat-generating fabric layer 4 is provided between the cashmere fabric layer 1 and the nano-level antibacterial film layer 2. The moisture-absorbing and heat-generating fabric layer 4 is made of moisture-absorbing and heat-generating acrylic fiber yarn. The moisture-absorbing and heat-generating fabric layer 4 makes this fabric suitable for spring, autumn, or early winter seasons when temperatures are not high.

[0028] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
