[0017] The present invention is further described in detail below in conjunction with specific embodiments and drawings.

[0018] The production process of antibacterial, high-elastic, high-density, crisp and soft knitted fabrics is as follows: weaving → pre-treatment → dyeing → dehydration → stretching and drying → modification and finishing → shaping;

[0019] (1) During weaving: The fabric is woven from 50-80S tight spinning, 50D / 36F-75D / 36F polyester low-elastic yarn, and 30D-70D high-elastic spandex yarn on a high-needle and high-density weft knitting double-sided machine. The fabric is a weft-knitted five-layer air layer fabric. The high-needle and high-density weft knitting double-sided machine has a barrel diameter of 34 inches, a machine gauge of 34 needles / 25.4mm, and a total number of 3,400 needles. The mass of the tight spinning in the fabric accounts for 60-72%, and the mass of the polyester low-elastic yarn accounts for 20-

[0020] 25%, high elastic spandex yarn accounts for 8-15%. Figure 1 As shown, weaving process: A, B

[0021] Two types of knitting needles are arranged in a matching way. The models of the two types of knitting needles A and B are as follows: Upper needle plate A: Vota 65.41G004,

[0022] Upper needle plate B: Vo 65.41G007, lower needle cylinder A: Vota 122.41G01, lower needle cylinder B:

[0023] Vo-LS122.41G01; needle arrangement is: the lower needle cylinder has two sections of needles A and B as one cycle, the upper needle disc has two sections of needles B and A as one cycle, each section forms a cycle with 6 routes, of which the 1st, 2nd, 4th and 5th routes are tight spinning, the 3rd and 6th routes are polyester low-elastic yarns, and high-elastic spandex yarns are added to the 1st, 2nd, 4th and 5th routes; the knitting method is: the first route: no knitting is done on the knitting needles at A and B of the lower needle cylinder to form floating threads, and the knitting needles at A and B of the upper needle disc are knitted into threads. Loop knitting; the second route: loop knitting is performed on the knitting needles at A and B of the lower needle cylinder, and no knitting is performed on the knitting needles at A and B of the upper needle disk to form floating threads; the third route: no knitting is performed on the knitting needle at A of the lower needle cylinder to form floating threads, tuck knitting is performed on the knitting needle at B of the lower needle cylinder, tuck knitting is performed on the knitting needle at A of the upper needle disk, and no knitting is performed on the knitting needle at B of the upper needle disk to form floating threads; the fourth route: no knitting is performed on the knitting needles at A and B of the lower needle cylinder to form floating threads, and loop knitting is performed on the knitting needles at A and B of the upper needle disk;

[0024] The fifth route: loop knitting is performed on the knitting needles at A and B of the lower needle cylinder, and no knitting is performed on the knitting needles at A and B of the upper needle disk, resulting in floating threads; the sixth route: tuck knitting is performed on the knitting needle at A of the lower needle cylinder, and no knitting is performed on the knitting needle at B of the lower needle cylinder, and no knitting is performed on the knitting needle at A of the upper needle disk, resulting in floating threads, and tuck knitting is performed on the knitting needle at B of the upper needle disk; in order to ensure that the fabric has the characteristics of high resilience, the traditional way of eating spandex on the upper needle disk has been changed from the traditional use of one upper needle disk Spandex pulley, the spandex yarn passes directly through the spandex pulley of the upper needle disc and can only be added to the back side of the fabric. After many tests, it was adjusted to use a spandex pulley on the upper needle disc and a spandex pulley on the lower needle cylinder. The high-elastic spandex yarn is first wrapped around the spandex pulley on the upper needle disc and then passes through the spandex pulley on the lower needle cylinder, so as to be added to the front and back sides of the fabric. In this way, the traditional fabric adding spandex on one side is improved to adding spandex on both sides of the fabric, which improves the resilience of the fabric. According to the national standard FZ / T 70006-2022 "Test method for stretch elastic recovery rate of needle fabrics", the specific values ​​are shown in Table 2 and Table 3. By comparing the average values ​​of Table 2 and Table 3, the average values ​​of the vertical stretch, horizontal stretch, vertical recovery and horizontal recovery of the double-sided spandex fabric are 30% higher than the average values ​​of the four indicators of the single-sided spandex fabric.

[0025] Almost, it proves that the double-sided spandex fabric has higher elasticity than the traditional single-sided spandex fabric;

[0045] Warmth test

[0046] Referring to GB / T11048-2008 "Determination of thermal resistance and moisture resistance of textiles under steady-state conditions of physiological comfort", the YG60 6 flat-plate fabric insulation instrument was used to test the thermal insulation performance of fabrics. Three 300mm×300mm specimens were cut from different parts of the fabric and completely covered on the test plate, protection plate and bottom plate at a temperature of 33℃. The thermal insulation rate and cro value of the test specimens were tested.

[0047] Anti-pilling test

[0048] The pilling resistance refers to the standard GB / T4802-2008 "Determination of pilling properties of textile fabrics Part 3: Pilling box method", which simulates the pilling condition of the fabric when it is subjected to self-or external friction, and evaluates the pilling grade.

[0049] Air permeability test

[0050] The air permeability test was carried out according to the standard GB / T5453-1997 "Determination of air permeability of textile fabrics". The pressure difference of the sample was set to 100Pa and the test area was 20cm 2 , repeat the test 10 times on different parts of the same sample. Calculate the air permeability of the fabric.

[0051] Antibacterial performance test

[0052] The antibacterial performance test is based on FZ / T73023-2006 "Antibacterial Knitwear". According to the test requirements of antibacterial level AAA, the fabric is washed 50 times and then tested for its inhibition rate against Escherichia coli, Staphylococcus aureus and Candida albicans using the oscillation method.

[0053] Results and Analysis

[0054] Warmth

[0055] The factors that determine the warmth retention of fabrics are the heat transfer coefficient and the Crowe value. The larger the heat transfer coefficient, the better the thermal conductivity of the fabric, and the worse the thermal insulation, resulting in worse warmth retention of the fabric. The larger the Crowe value, the better the warmth retention. The test results of the warmth retention of fabrics are shown in Table 4:

[0056] Table 4

[0057]

[0058]

[0059] The fabric has a thermal insulation rate of 36.09%, a heat transfer coefficient of 20.36 W / m2.℃, and a clo value of 0.31 clo. Referring to the FZ / T73022-2019 "Knitted Thermal Underwear" standard, the thermal insulation rate requirements for superior, first-class, and qualified products [5], it can be seen that the fabric prepared in the present invention has excellent thermal insulation performance and is suitable for the thermal insulation requirements of autumn and winter clothing.

[0060] Breathability

[0061] The breathability of clothing fabrics affects the comfort of wearing. Therefore, the fabrics need to have a certain degree of breathability to allow the air in the clothing to be replaced in time to maintain comfort and cleanliness. The measured air permeability of the fabric is 192 mm / s, which meets the breathability requirements of knitted thermal underwear[6].

[0062] Antimicrobial properties

[0063] The antibacterial property of the fabric prepared in the present invention after washing 50 times is compared with that of FZ / T73023-2006 as shown in Table 5. It can be seen that the antibacterial rate of the fabric exceeds the AAA antibacterial effect standard value in the standard and has excellent antibacterial property.
