Background technique

With the increasing awareness of health care, the requirements for textiles have gradually expanded from soft and comfortable, moisture absorbing, wind and rain to anti-UV, far infrared, antibacterial deodorization, mildew proof, antistatic and other functional aspects. The development and application of various new fabrics and the development of new technologies and new technologies have made these requirements gradually realized. In recent years, functional and health-care fabric apparel has become the darling of fashion, and has repeatedly become the protagonist of the fabric clothing exhibition. The research and development of functional knitted fabrics in foreign countries is concentrated in the research of fibers and yarns, that is, the development of fibers and yarns with antibacterial, antistatic and far infrared functions. Mainly using physical or chemical methods, the functional substance map antibacterial agent, ceramic powder, etc. are introduced into the fiber surface or inside the fiber to make it have antibacterial, far infrared, anti-ultraviolet and other functionalities. For example, by adding a special ceramic powder containing chromium oxide, magnesium oxide, zirconium oxide or the like, particularly a nano-sized fine ceramic powder, to a synthetic fiber spinning solution such as polyester, the fiber has a far-infrared function. In recent years, with the transformation and upgrading of China's textile industry, domestically, we have been studying functional knitted fabrics. Textile companies continue to adopt new technologies, new raw materials and new processes, keep pace with the times, cross-disciplinary and develop high value-added Technology fabrics to meet people's needs, while guiding and promoting the development trend of new textile products. However, due to the development of functional fibers, high cost, large investment, and difficulty in achieving large-scale industrialization, and the functional fabrics realized by the finishing method, along with the continuous improvement of living standards, people’s requirements for clothing are more Heavy functionality, environmental protection and health care. The production and sales of functional textiles have also expanded. At present, global functional textiles have annual market sales of about $80 billion, while domestic functionality is relatively low in cost, short-lived, and relatively affordable. At present, most of the functional fabrics on the domestic market are realized through post-finishing.

Its functionality is produced by a quantum energy powder, which is a submicron ultrafine powder with a particle size of about 500 nm. The ingredients are silica and aluminosilicate. The powder has far infrared, anti-ultraviolet and antibacterial effects, so the quantum energy polyester fiber is a functional fiber having far infrared, ultraviolet and antibacterial properties. However, the quantum energy polyester fiber has a low moisture regaining rate and poor cohesion, and the obtained fabric has poor moisture absorption and permeability, is easy to pilling, and has a serious electrostatic phenomenon. Elastomeric fiber ZENTRA is a new type of polyester material independently developed by Korea Huiweis.

detailed description

The invention will be further described and described in conjunction with the specific embodiments thereof in order to understand the understanding of the invention.

Example 1:

The preparation method of the high elastic soft knitted fabric comprises the following steps: 1) raw material matching; main indexes of the quantum energy polyester fiber: fiber linear density 1.44 dtex, length 38 mm, elongation at break: 21.2%, fracture Strength: 6.17cN/tex, crimp number 12, specific resistance 2.3, oil content 2.4; main indexes of elastic fiber: fineness 1.33dtex, length 40mm, moisture regain ratio 0.49%, specific resistance 2.78; wooddale fiber Main indicators: fineness 1.3dtex, length 39mm, strength: 5.13cN/cm, moisture regain: 11.25%; the blending ratio of the three yarns is: quantum energy polyester 60%, wooddale fiber 20%, elasticity Fibers account for 20% or quantum energy polyesters account for 40% and wooddale fibers account for 60%. This blending ratio can ensure that the quantum energy polyester accounts for 50% of the fabric, maximizes the function of the quantum energy fiber, and improves the functionality of the knitted fabric; 2) the spinning process, in the spinning process, due to the elastic fiber ZENTRA is elastic, fluffy and has poor cohesion. To enhance its spinnability, firstly add a certain amount of antistatic agent, fiber weight and antistatic agent in the pre-spinning process. The ratio of the amount is 1:03%. For the knitting yarn of quantum energy polyester fiber 60/Mudal 20/elastic fiber 20 14.8 tex, the method of mixing quantum energy polyester fiber and elastic fiber cotton bag is adopted, and then with quantum A spinning process in which polyester fibers and modal fibers are each formed into a strip. For the knitting yarn of quantum energy polyester fiber 40/Mudal 60 14.8 tex, a spinning process in which the quantum energy polyester fiber and the modal fiber are each formed into a strip is adopted. For the quantum energy polyester fiber and elastic fiber after the cotton bale is mixed, in the opening process, combined with the characteristics of bulkiness, elasticity and poor saturation of the elastic fiber, it is necessary to appropriately reduce the opening force and reduce the speed of each beater, while avoiding More entanglement, reducing fiber damage and ensuring good roll. In the carding process, the polyester fiber is easy to adhere to the upper and lower rolls, the fiber damage is large, the cotton knot is many, the cotton net is easy to fall and the transfer is difficult and easy to break, and the process principle of low speed, light weight and large gauge should be followed; And the gap between the cotton board, properly reduce the spacing between the cylinder and the cover plate, the use of new metal card clothing, reduce fiber deposition, is conducive to fiber transfer, reducing the incidence of short piles and neps. The Modal fiber has good uniformity and is relatively straightforward, and it is easy to open. Therefore, a short process should be adopted, which is mainly based on opening and loosening, reducing the hitting point, combing and playing, combing and playing less, and controlling the rate of falling cotton. The carding process needs to reduce the speed of the licker and the cylinder and increase the gauge between the cover and the cylinder. In the drawdown process, the quantum energy polyester/elastic fiber pre-strand, the quantum energy polyester pre-strand and the modal pre-adhesive are mixed on the head draw frame, and the four passes are used to ensure uniform mixing. Due to the large elasticity of the PTT fiber and the large drafting force in the rear zone, the drafting ratio of the main drafting zone should be appropriately reduced when the drafting ratio is selected, and the rear zone should be appropriately increased. The drafting ratio of the rear zone of the second and third passes should be appropriately reduced. The pressure of the large cradle and the tension of the front bead increase the level of the strip of the cooked strip. In the roving process, the process principle of slow speed, heavy pressurization, large rear roller spacing and maximizing the total draw ratio is used. Maximize the total draw ratio as much as possible to reduce the total draw ratio of the spinning process, which is beneficial to the fine yarn Control of the fibers during the drawing process. The spinning process adopts the principle of heavy pressurization, large rear zone drafting distance, and small rear zone drafting multiple, reducing the generation of details and strong weak rings.
