Abstract
Description
Technical Field
[0001] The utility model relates to the field of textiles, in particular to a printed knitted fabric with a degradable coating. Background Art
[0002] Although the current pollution of the ecological environment by the printing and dyeing industry is not as serious as that by the chemical industry, it cannot be ignored either. Especially in the context of advocating ecological protection and pursuing sustainable development, printing companies in the printing and dyeing industry have gradually become one of the key pollution rectification targets.
[0003] The pigment part of traditional printing paint is mainly composed of heavy metal substances. Therefore, during the printing and dyeing process, heavy metal substances will inevitably diffuse into the external environment. Heavy metal substances are difficult to decompose under natural conditions, which leads to serious pollution of the ecological environment by traditional printing and dyeing processes and traditional fabrics. Utility Model Content
[0004] The utility model aims to overcome the above-mentioned deficiencies of the prior art and provide a printed knitted fabric with a degradable coating.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A printed knitted fabric with a degradable coating. The knitted fabric is made of 30S combed compact-spun cotton yarn, 30S carded ring-spun cotton yarn and 30D spandex filament as raw materials and is combined with a padding tissue as a basic structural unit. The 30S combed compact-spun cotton yarn and the 30D spandex filament are knitted in the second and fourth routes and are knitted into loops on each knitting needle; the 30S carded ring-spun cotton yarn is knitted in the first and third routes, and is knitted into loops on the second and fourth knitting needles of the first route, and is not knitted on the first and third knitting needles; and is knitted into loops on the first and third knitting needles of the third route, and is not knitted on the second and fourth knitting needles. Nanocellulose printing coating is provided on the knitted fabric.
[0007] Preferably, the 30S combed compact-spun cotton yarn is 16CM / 50N long.
[0008] Preferably, the 30S carded ring-spun cotton yarn is 6.2CM / 50N long.
[0009] Preferably, the 30D spandex filament yarn is 5.4CM / 50N long.
[0010] Preferably, the knitted fabric has a gram weight of 240 g / m2.
[0011] Preferably, the effective width of the knitted fabric is 178CM.
[0012] Preferably, the knitted fabric is woven by a 34-inch 24-needle double-sided machine.
[0013] The beneficial effects of the utility model are:
[0014] 1. Loops are knitted on each of the knitting needles of the second and fourth routes of the knitted fabric to improve the dimensional stability of the knitted fabric and prevent the knitted fabric from being easily deformed. The first and third knitting needles of the first route of the knitted fabric do not participate in the knitting, and the second and fourth knitting needles of the third route do not participate in the knitting, that is, air holes are formed at the places not involved in the knitting to improve the overall air permeability of the knitted fabric. At the same time, the knitted fabric uses spun cotton yarn as the main raw material, and thus has good skin affinity and degradability, and is not easy to pollute the environment. The printing pigment with good degradability is developed using nanocellulose, which further improves the degradability of the knitted fabric and is more in line with the market demand for green environmental protection.
[0015] 2. Nanocellulose has the characteristics of being renewable and biodegradable, and is relatively friendly to the skin. It can not only reduce the irritation of paint to the human body, but also reduce the toxicity of paint wastewater to reduce pollution to the environment. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 This is a weaving process diagram of the utility model. DETAILED DESCRIPTION
[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:
[0018] In the description of this specification, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.
[0019] like Figure 1 As shown, a printed knitted fabric with a degradable coating is used. The knitted fabric is made of 30S combed compact spun cotton yarn, 30S carded ring spun cotton yarn and 30D spandex filament as raw materials, and is combined with a padding tissue as a basic structural unit (woven into a terry cloth). The 30S combed compact spun cotton yarn is 16CM / 50N long, the 30S carded ring spun cotton yarn is 6.2CM / 50N long, and the 30D spandex filament yarn is 5.4CM / 50N long. The usage ratio of the 30S combed compact spun cotton yarn, the 30S carded ring spun cotton yarn and the 30D spandex filament is 69:27:4. The effective width of the knitted fabric is 178CM, and the gram weight of the knitted fabric is 240 grams per square meter.
[0020] The knitted fabric is woven by a 34-inch 24-needle double-sided machine. The 30S combed compact-spun cotton yarn and 30D spandex filament are woven in the second and fourth routes and are woven into loops on each knitting needle to improve the dimensional stability of the knitted fabric, making the knitted fabric less likely to deform and increasing the service life of the knitted fabric.
[0021] The 30S carded ring-spun cotton yarn participates in weaving on the 1st and 3rd routes, and tucks are weaved on the second and fourth knitting needles of the 1st route, and does not participate in weaving on the first and third knitting needles, and tucks are weaved on the first and third knitting needles of the 3rd route, and does not participate in weaving on the second and fourth knitting needles, that is, the first and third knitting needles of the 1st route of the knitted fabric do not participate in weaving, and the second and fourth knitting needles of the 3rd route do not participate in weaving, so as to form air holes in the knitted fabric at the non-weaving locations, so as to improve the overall air permeability of the knitted fabric.
[0022] The knitted fabric uses spun cotton yarn (30S combed compact-spun cotton yarn and 30S combed ring-spun cotton yarn) as the main raw material, which makes the knitted fabric itself have good skin-friendliness and biodegradability, which not only improves the comfort when in contact with the body, but also can be degraded and is not easy to pollute the environment.
[0023] By knitting tucks on the second and fourth needles of the first route of the knitted fabric and knitting tucks on the first and third needles of the third route, an outwardly convex feel is generated at the tucks of the knitted fabric, thereby increasing the tactile feel of the knitted fabric.
[0024] The knitted fabric is provided with a nanocellulose printing paint, and the nanocellulose is sourced from natural plants that are easy to dye, such as madder, gardenia, indigo, comfrey, frost green and various teas. Therefore, the printing paint developed with nanocellulose has the characteristics of being renewable and biodegradable. It is used to replace the existing difficult-to-degrade paint, further improving the degradability of the knitted fabric and better meeting the market demand for green and environmental protection.
[0025] Nanocellulose has good skin-affinity effects. Using nanocellulose printing paint can not only reduce the irritation and harm of the paint to the human body, but also reduce the toxicity of paint wastewater, reduce the burden of paint wastewater treatment, and reduce pollution to the environment.
[0026] Nanocellulose itself also has good uniformity, weather resistance, and biocompatibility. The knitted fabrics produced using nanocellulose printing coatings have brighter and softer colors.
[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
