Description

Double needle bed tubular split webbing

Technical field

The invention relates to the technical field of webbing, in particular to a double needle bed tubular split webbing and high-grade underwear made of the fabric and others.

Background technique

At present, webbing is widely used in the textile industry and other daily life. The apparel industry is widely used. The webbing has become an indispensable part of underwear production. With the development of technology, people's living standards have improved significantly. The requirements for production are also getting higher and higher, and the styles and types of underwear on the market are also increasingly numerous, such as casual underwear, sports underwear, functional underwear, adjustable underwear, etc.; in order to make the appearance of the underwear and achieve specific functionality, The split webbing begins to be used in the underwear. Regarding the split-fork webbing, the traditional method is to take the corresponding number of webbings and sew them together according to the required forks, and the outer bread cloth is processed. This method not only affects the seam position, but also affects the elastic use of the webbing, and has many processes. Complex, low production efficiency, not conducive to production, and the production of underwear due to the belt is not smooth, poor comfort, can not meet the increasingly relevant requirements in the field of underwear production. With the development trend of the market, the current knitting belt machine and the woven belt machine can integrally weave a variety of forked split webbings according to the requirements, such as the patents disclosed by Mingxin Company: a kind of patent that can change the length of the fork at will. Trigeminal webbing. However, the integrated woven cross-cut webbing is only subject to the raw materials used, the structure of the process (both solid webbing) and the like, and only achieves the seamless connection of the webbing, simplifies the production process and enhances the aesthetics of the underwear, but the webbing is The "I-shaped" part is easy to wrinkle, and the elastic recovery, strength, skin, feel, moisture absorption, and breathability are not good enough to meet the high demands of people for underwear production. A novel functional webbing is disclosed: a double needle bed tubular split webbing, the fabric of the invention has soft hand feeling, moisture absorption, sweat absorption and fabric elasticity. Good resilience, memory function, 360 degree free telescopic recovery, no tension or tightness after wearing, and the split section and the solid section are not wrinkled, not scratched, smooth, smooth; The fabric realizes the concept of integrated weaving, which saves the sewing time and reduces the production cost. The beautiful, comfortable and seamless products are more beautiful and skin-friendly.

Summary of the invention

The purpose of the fabric of the present invention is to provide a double needle bed tubular split webbing, which is woven by a double needle bed Raschel warp knitting machine, and sequentially weaves a single-sided structure in the front needle bed F and the rear needle bed B, and Two layers of single-sided fabric are connected up and down on two sides to form two parallel tubular structure fabrics, and then two warp-knitted fabrics are knitted into a continuous structural surface after a certain process cycle by using a warp knitting process. Finally, a tubular fabric having a certain closed and split cycle is formed.

The solution for the I-shaped part of the back of the traditional underwear is to wrap the elastic sheet material through cloth or cloth and then to realize the sewing. The defects are as follows: 1. Due to the elastic property of the cloth itself and the manner of wrapping, the elastic performance of the underwear is not good; The sewing seam makes the connection position of the underwear unattractive, uneven, smooth and affects the softness and comfort of the underwear. 3. The sewing process is complicated, complicated, low in production efficiency and high in production cost.

A kind of split webbing that appears on the market, although the seamless connection of the webbing is realized, the production process is simplified, and the aesthetics of the underwear is enhanced. However, due to factors such as raw materials and process structures (both solid webbing), the type of the word is easy. Wrinkles are uneven, easy to deform, and elastic recovery, strength, skin-feeling, hand-feeling, moisture absorption and ventilation are not good.

The fabric of the present invention solves the above problems well:

1. The structure of the fabric of the present invention is consistent with the structure of the underwear fabric, and the appearance of the webbing can be achieved with the underwear. Perfect combination; 2, the fabric of the invention is hollow, relatively solid webbing, the hollow structure design can make the hand feel softer and the breathability is better; 3. The fabric material of the invention adopts 100% finer yarn and uses spandex or spandex package at the same time. The core yarn makes the fabric have a memory function, and can be retracted and retracted 360 degrees freely. After the force of the split section, the two sides of the I-shaped part will not wrinkle, so the present invention is better in conformity with human physics, and does not wear after the body. There will be a sense of tension and tension, especially during exercise, the webbing can freely retract and retract with the movement of the human body, reducing the binding force of the human body, making it more skin-friendly and comfortable;

The fabric of the invention has soft hand feeling, moisture absorption, sweat absorption, good elastic recovery property of the fabric, memory function, 360 degree free telescopic recovery, no feeling of feeling or tightness after wearing, and the split section and the solid section are not wrinkled or The new fabric realizes the concept of integrated weaving, which saves the sewing time and reduces the production cost. The beautiful, comfortable and seamless products are more beautiful and skin-friendly.

In order to achieve the above effects, the technical solution adopted by the present invention is:

The double needle bed tubular split webbing of the invention is woven by the E24 double needle bed computer warp knitting machine (Raschel, which is a raschel warp knitting machine), and the machine is generally used for braiding rope, color strip, double ribbing. Warp-knitted fabrics with a non-elastic structure such as fabric and a rough appearance, and a rough handle, are now developed from the aspects of machine equipment, product process design, and raw material use specifications, so that they can produce a delicate appearance, soft hand and superiority. The flexible double needle bed tubular split fabric makes it suitable for use in the field of underwear products.

The utility model is characterized in that a single-layer fabric is woven in the front needle bed F and the rear needle bed B of the Raschel double needle bed warp knitting machine, and two sides of the single-sided fabric are connected up and down to form two parallel tubular structures. The fabric is further knitted into a piece of connected structural surface after a certain process cycle by using a warp knitting process by using a warp knitting process before and after the double needle bed, thereby finally forming a tubular fabric having a certain closed and split cycle;

The single-sided structure of the above-mentioned one-side structure is positively conveyed to the handpiece by a certain amount of yarn through the pan head ring, and is woven according to the requirements of the fabric structure, and the weaving structure principle can be: flat structure, warp satin Organized, reorganized organizations and other warp organizations;

The double-layer fabric is woven at the same time according to the double needle bed double-sided tissue process, and the two sides of the double-layer fabric are connected one on top of the other, and the process of connecting the two sides of the front and back sheets is a change of the chain structure, that is, the yarn according to a certain process rule. Weaving on the same needle of the front and rear needle beds to join the two sides together; the process of connecting the closing and splitting portions in the middle of the front and back sheets is a combination of a double-sided flattening process and a change of braiding, that is, in the closed section The double-sided flattening process is adopted, and the splitting section adopts a change chaining process.

In the above tubular split fabric, the closed section is controlled by machine equipment after being woven into two parallel tubular structures through the front and rear needle beds, and according to the actual needs of the process, the double needle bed is used at the same time as the double needle bed. The yarns on the adjacent sides of the two parallel tubular fabrics are alternately woven into a closed section.
