Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fabrics, in particular to a warm knitted fabric. Background Art
[0002] At present, many people do physical fitness in the autumn and winter seasons. In order to ensure that the clothes can still be worn comfortably after exercise, manufacturers will use moisture-absorbing and quick-drying fabrics to make sportswear. However, these sportswear have a single function and can only absorb sweat quickly, but the warmth retention effect is poor. They are not suitable for wearing in autumn and winter, especially when outdoors. It is easy to catch a cold after exercise, which affects your health. Summary of the Invention
[0003] In order to solve the above technical problems, the utility model provides a warm knitted fabric that can adapt to sports needs and has a good warming effect.
[0004] The technical solution is as follows: A warm knitted fabric, characterized in that it includes an outer layer, a middle layer and an inner layer, the outer layer and the middle layer are composed of a knitted double-sided fabric structure, the outer layer is a flat surface and the middle layer is an inwardly convex surface, the weaving structure has four routes as a complete weaving cycle, wherein the first and third routes are respectively an upper dial needle looping structure and a lower cylinder needle floating thread structure, the second route is an upper dial needle floating thread structure and a lower cylinder needle looping structure, and the fourth route is an upper dial needle tucking structure and a lower cylinder needle tucking structure, and the lower cylinder needles pull out needles every other one or every other two to form a micro-channel structure in the structure of the middle layer;
[0005] The inner layer is a single-sided pile fabric, and the weaving structure has nine routes as a complete organizational cycle and there are three types of needles: a, b, and c. The first route is the a needle tuck structure, b needle float thread, and c needle float thread, respectively; the second, third, fifth, sixth, eighth, and ninth routes are the a needle loop structure, b needle loop structure, and c needle loop structure, respectively; the fourth route is the a needle float thread, b needle tuck structure, and c needle float thread, respectively; the seventh route is the a needle float thread, b needle float thread, and c needle tuck structure, respectively.
[0006] Its further feature is that the outer layer is a PTT layer, the middle layer is a polyester low-elastic yarn layer, and the inner layer is a polypropylene layer.
[0007] After adopting the utility model, the fine channels formed in the middle layer can allow the water in the inner layer to be quickly transferred to the outer layer, that is, the sweat retained in the fiber is absorbed and discharged from the fabric, so that the inner layer close to the body is always kept dry. At the same time, due to the existence of the middle layer, a large amount of static air is retained between the inner and outer fabrics, achieving a high warmth-keeping effect. The inner layer of fleece fabric also has good warmth-keeping properties. The entire fabric is suitable for making autumn and winter clothing. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 This is a schematic diagram of the fabric of the utility model;
[0009] Figure 2 This is a schematic diagram of the weaving triangle of the inner layer of the utility model;
[0010] Figure 3 This is a schematic diagram of the weaving triangles of the outer layer and the middle layer of the utility model. DETAILED DESCRIPTION
[0011] See Figure 1 , Figure 2 , Figure 3 The figure shows a warm knitted fabric comprising an outer layer 1, a middle layer 2, and an inner layer 3. The outer layer 1 and middle layer 2 are constructed from a double-face knit fabric structure. The outer layer 1 is flat, and the middle layer 2 has an inwardly convex surface. The weaving structure consists of four loops, each consisting of a complete weave cycle. The first and third loops, respectively, consist of a dial-stitch looping structure followed by a cylinder-stitch float. The second loop consists of a dial-stitch float and a cylinder-stitch looping structure. The fourth loop consists of a dial-stitch tuck and a cylinder-stitch tuck. The cylinder-stitch needles are spun every other needle or every other needle, creating "channels" in the middle layer 2, forming microchannels that rapidly transfer moisture from the inner layer to the outer layer. The outer layer 1 is made of PTT yarn, which has strong moisture absorption and dissipation capabilities, while the middle layer 2 is made of polyester low-stretch yarn with a special-shaped cross-section.
[0012] The inner layer 3 is a single-faced fleece fabric, which enhances its close-fitting warmth. The weave consists of nine loops, each with three stitch patterns: a, b, and c. The first loop consists of a tuck stitch, b float stitch, and c float stitch. The second, third, fifth, sixth, eighth, and ninth loops follow a loop stitch, b loop stitch, and c loop stitch, respectively. The fourth loop follows a float stitch, b tuck stitch, and c float stitch. The seventh loop follows a float stitch, b float stitch, and c tuck stitch. The inner layer is constructed of water-resistant and lightweight polypropylene.
[0013] Because both the inner and middle layers are composed of water-repellent fibers, the outer layer not only absorbs moisture from the surfaces of the two layers, but also forms microchannels in the middle layer that draw sweat trapped within the fibers away from the fabric, keeping the next-to-skin inner layer dry. Furthermore, the middle layer traps a large amount of stagnant air between the front and back fabrics, achieving a high degree of warmth retention. Furthermore, the inner layer's brushed fabric imparts exceptional softness, abrasion resistance, stretchability, and elasticity, making it comfortable and durable, making it ideal for autumn and winter apparel.
