Description

Technical Field

[0001] This utility model relates to a burnout knitted fabric and a knitted sweater, belonging to the technical field of burnout knitted fabrics. Background Technology

[0002] With continuous economic development and the gradual improvement of living standards, consumers' consumption concepts regarding knitwear have undergone significant changes. Beyond basic functionalities such as warmth and comfort, they also seek aesthetically pleasing fabrics. Jacquard or embroidered fabrics are favored by consumers due to their exquisite appearance. However, the production speed of jacquard and embroidered fabrics is low, and embroidery can affect the breathability of knitwear, especially for summer sweaters. These sweaters require both coverage and good breathability to enhance comfort during summer wear. Therefore, developing a breathable knitted fabric for summer sweaters has become a key problem to be solved. Utility Model Content

[0003] The purpose of this utility model is to provide a burnished knitted fabric and a knitted sweater, which has a ground part exposed after burnishing, which not only forms a set floral pattern, but also improves breathability.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0005] The present invention relates to a burnout knitted fabric, comprising a fabric greige woven from knitting yarn, wherein the fabric greige woven from yarn has a ground portion and a pattern portion formed after burnout.

[0006] The braided yarn is a parallel arrangement of alkali-resistant yarn and animal protein fiber yarn, or a twisted combination of alkali-resistant yarn and animal protein fiber yarn, or a core-spun yarn of alkali-resistant yarn and animal protein fiber.

[0007] The alkali-resistant yarn / animal protein fiber core-spun yarn includes a core yarn and a covering fiber layer, wherein the core yarn is an alkali-resistant fiber and the covering fiber layer is an animal protein fiber.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the alkali-resistant yarn is nylon filament, nylon staple yarn or nylon-viscose blended yarn; the fineness of the animal protein fiber yarn is 20-30 count.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the fabric greige is woven from knitting yarn using a 12-needle computer flat knitting machine.

[0010] Based on the above scheme and as a preferred option, the animal protein fiber yarn used is made of wool fiber, cashmere fiber, rabbit hair fiber, yak hair fiber, yak cashmere fiber or camel hair fiber.

[0011] This utility model also relates to a knitted sweater, including the above-mentioned burnout knitted fabric.

[0012] The beneficial effects of this utility model are as follows: The burnout knitted fabric and knitwear involved in this utility model use alkali-resistant yarns. When burnout is performed using caustic soda, the alkali-resistant yarns are unaffected, ensuring the strength of the knitted fabric. The exposed ground area after burnout provides good breathability. The retained portion forms a floral pattern, which serves both aesthetic and concealing purposes. Attached Figure Description

[0013] Figure 1 This is a structural schematic diagram of the burnout knitted fabric involved in Example 1.

[0014] The markings in the diagram are explained as follows: 1 - Ground; 2 - Pattern. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Example 1

[0017] Combination Figure 1 This embodiment will be described in detail below. The burnout knitted fabric involved in this embodiment includes a fabric lining woven from knitting yarns. The fabric lining has a ground portion 1 and a pattern portion 2 formed after burnout. In this embodiment, the fabric lining is selected as a knitted garment piece knitted on a 12-gauge computerized flat knitting machine. Of course, the fabric lining can also be knitted on a computerized flat knitting machine with other gauges, depending on actual needs. Furthermore, in this embodiment, the fabric lining uses a warp-knitted plain knit structure, but other warp-knitted structures can also be selected for knitting as needed.

[0018] The knitting yarn can be a parallel alkali-resistant yarn and an animal protein fiber yarn, or a twisted alkali-resistant yarn and an animal protein fiber yarn, or an alkali-resistant yarn / animal protein fiber core-spun yarn. That is, there are three options for the knitting yarn: First, a parallel alkali-resistant yarn and an animal protein fiber yarn, specifically, during knitting, the alkali-resistant yarn and the animal protein fiber yarn are fed parallel into the computerized flat knitting machine, and both yarns are knitted simultaneously. Second, a twisted alkali-resistant yarn and an animal protein fiber yarn, that is, the alkali-resistant yarn and the animal protein fiber yarn are first twisted together, which can be done using Sirofil yarn, to form a twisted yarn. During knitting, a single twisted yarn is fed into the computerized flat knitting machine for knitting. Third, an alkali-resistant yarn / animal protein fiber core-spun yarn. The alkali-resistant yarn / animal protein fiber core-spun yarn includes a core yarn and a covering fiber layer, wherein the core yarn is alkali-resistant fiber, and the covering fiber layer is animal protein fiber. During weaving, alkali-resistant yarn / animal protein fiber core-spun yarn is fed individually into a computerized flat knitting machine for weaving. In this embodiment, the first method is selected, that is, the alkali-resistant yarn and the animal protein fiber yarn are parallel.

[0019] Furthermore, the alkali-resistant yarn is nylon filament, nylon staple yarn, or nylon-viscose blended yarn; the fineness of the animal protein fiber yarn is 20-30 count. In this embodiment, nylon-viscose blended yarn is selected, specifically 40% nylon 6 fiber and 60% viscose fiber. The fineness of the animal protein fiber yarn is 25 count.

[0020] Furthermore, the animal protein fiber yarn used is made of wool, cashmere, rabbit hair, yak hair, or camel hair. In this embodiment, semi-worsted wool yarn is selected.

[0021] The woven fabric is coated with a burning paste containing caustic soda using a flatbed printing method according to the designed pattern. It is then baked at 80-100℃ for 15-20 minutes, which destroys the animal protein fibers in the coated area. The fabric is then washed in a washing machine to remove the caustic soda paste and the coated animal protein fibers, forming the ground area 1, while the remaining area is the pattern area 2. In the ground area 1, the animal protein fibers are burned away, leaving only the alkali-resistant yarn, which greatly increases the breathability of the ground area, thus improving comfort during summer wear.

[0022] This embodiment also relates to a knitted sweater, including the burnished knitted fabric. The sweater is formed by sewing together the individual burnished knitted pieces.

[0023] Example 2

[0024] The burnout knitted fabric involved in this embodiment differs from that in Embodiment 1 in that the knitting yarn also includes low-melting-point nylon filaments twisted together with alkali-resistant yarns. The melting point of these nylon filaments is 80-110℃, and in this embodiment, 110℃ is selected. Heating the patterned portion until the low-melting-point nylon filaments melt and adhere to the animal protein fibers reduces yarn shedding from the patterned portion 2.

[0025] The specific low-melting-point nylon filament consists of a sheath and a core. The sheath is low-melting-point nylon 6 with a melting point of 110℃. The core is conventional nylon 6 with a melting point of 263℃.

[0026] 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.
