Description

Technical Field

[0001] The invention belongs to the technical field of textiles, and in particular relates to a multifunctional fabric which is soft, lightweight, and has both warm-keeping and antibacterial effects. Background Art

[0002] As people's living standards continue to improve, their pursuit of quality of life is getting higher and higher. Many comfortable fabrics that can bring new wearing experiences are sought after by people. The most direct and effective way to change the style and performance of fabrics is to introduce new yarns.

[0003] The method of spinning different fibers together to obtain yarns with new properties is a common method for developing new yarns. In recent years, with the continuous emergence of new textile materials and textile technologies, more and more blended yarns have flooded into the market. Polyester is one of the most popular fibers among chemical fibers, but polyester fabrics have the following disadvantages: 1) Polyester fabrics have poor antistatic ability due to their poor hygroscopicity; antistatic finishing of fabrics can be achieved through yarn performance or through fabric finishing, but the latter often has undesirable phenomena such as poor performance and excessive chemicals. Therefore, it is the most reasonable and simplest method to give textiles the above properties by changing yarn properties.

[0004] Nylon fiber generally has the properties of softness and high moisture absorption. Therefore, adding a small amount of nylon fiber to the yarn can also improve the conductivity of the yarn. However, the structure of the polyester-nylon composite yarn commonly used on the market is not stable enough and the performance is single. Therefore, improving the structural stability and functionality of the polyester-nylon composite yarn is the key to increasing the added value of this type of fiber. Grass coral fiber is made of natural plant grass coral as raw material and blended with viscose spinning solution. On the basis of retaining the good spinnability and comfort of cellulose fiber, it reflects the unique efficacy of grass coral plant. It is a new generation of natural, green and healthy fiber. Grass coral fiber has natural plant antibacterial function. The six main chemical components in grass coral are: astilbin, isoflavones, rhamnosyl glucoside, tannin, fraxin, fraxin, fraxinin, they generally have antibacterial and anti-inflammatory effects, and have good antibacterial and antibacterial effects on Staphylococcus aureus, Candida albicans and Escherichia coli.

[0005] In summary, the market is in urgent need of multifunctional fabrics, and there is also an urgent need to upgrade and combine a variety of fibers to form products with a more comfortable experience. Summary of the invention

[0008] The obtained copper ion modified polyester chips and polyamide chips are dried and then melted to obtain polyester spinning melt and nylon spinning melt; the polyester spinning melt and the nylon spinning melt are mixed in a mass ratio of 4: (0.5-1) and spun, cooled, cut and oiled to obtain nylon-polyester composite fibers with copper ion antibacterial properties.

[0009] Furthermore, the Australian wool is selected from 80s Australian wool with uniform length and fineness, good curl and sufficient elasticity, an average length of 5-7CM, and a fineness of 18.5um.

[0010] Furthermore, the coral grass fiber is dyed and dried before spinning, the dyeing temperature is 75°C, and the fiber is dried in a radio frequency dryer at a speed of 35m / h and a drying temperature of 80°C.

[0011] Furthermore, the twist of the core layer is 220T / M, with a twist direction of Z twist, and the twist of the covering layer when it is wrapped around the core layer is 210T / M, with a twist direction of S twist.

[0012] Furthermore, the fabric is processed through the steps of washing, shrinking, washing, steaming, raising, pricking, shearing, steaming and pre-shrinking.

[0013] Furthermore, during the shrinking, 50-60 G / L of diacetone acrylamide-based polymer is added and treated at 60° C. for 10-20 minutes, so as to keep the core-filled yarn structure more fluffy.

[0014] Furthermore, the needle density during pile raising is 26 / cm, the needle diameter is 50um, and a fine needle light pulling process is adopted to achieve a fine surface, dense pile, sufficient elasticity, good fluffiness, rich hand feel, and good warmth retention.

[0015] Furthermore, the pre-shrinking process is performed by air flow pre-shrinking, the pre-shrinking temperature is 120° C., and the vehicle speed is 10 m / min.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] The multifunctional fabric of the present invention has the following advantages:

[0018] (1) The multifunctional fabric of the present application has the advantages of being soft, lightweight, warm and antibacterial. Nylon-polyester composite fiber has good antibacterial properties, fluffiness and softness and comfort, which increases the functionality of the core-filled weft; coral grass fiber can not only improve the antibacterial property, but also has the property of self-heating, which can effectively ensure the functionality of the core-filled weft; Australian wool has good elasticity, high fluffiness and strong softness, which ensures the comfort of the core-filled weft; the core-filled weft formed by the three fibers in proportion effectively ensures the functionality of the fabric.

[0019] (2) Blending nylon chips and modified polyester chips into yarn can effectively improve the static electricity problem of polyester fibers. Spinning nylon chips and modified polyester chips in two steps according to this ratio can ensure the antibacterial properties of the fibers on the one hand, and effectively utilize the different shrinkage properties of the two components on the other hand, making the fibers softer and fluffier.

[0020] (3) The double weft-core filling structure is adopted, so that the yarn with fluffy performance is sandwiched in the middle of the fabric as the core filling weft, and the yarn with skin-friendly performance is presented on the outside of the fabric as the surface and inner layer yarn, thereby ensuring the comfort, fluffiness and functionality of the fabric.

[0021] (4) Specific shrinking and needle punching processes are used during post-processing to ensure the fluffiness and velvet feel of the fabric, making the fabric more comfortable. BRIEF DESCRIPTION OF THE DRAWINGS
