(1) covering yarns: wrapping and winding spandex serving as an inner wrapping yarn and nylon serving as an outer wrapping yarn to obtain wrapped yarns;

(2) weaving: adopting a cylindrical weaving machine with a circular machine to perform exchange weaving on the fasciated yarn and the chinlon to obtain grey cloth;

(3) sewing: cutting and sewing the grey cloth to obtain clothes tubular cloth for facilitating subsequent dyeing and shaping;

(4) dyeing: dyeing the clothes tubular cloth to obtain colored tubular cloth with cutting lines;

(5) shaping: the colored clothes tube is shaped by an underwear shaping plate, and the anti-loosening and anti-snagging ultrathin function is given to the colored clothes tube;

(6) cutting: cutting the shaped tubular cloth according to a sample plate line, and cutting the tubular cloth into two sleeves and an underwear body;

(7) and (3) sewing: and after the sewing line is cut off from the underwear body with each sleeve, sewing the underwear bodies with the two sleeves, embedding a neckline and armholes, and tying and reinforcing the joints to obtain the ultrathin anti-loosening underwear.

Preferably, the type of the spandex is 15D-60D; the nylon is FDY/DTY 8D-70D.

Preferably, in the step (1), the twist of the wrapping is 1500-.

Preferably, in the step (2), the cylinder weaving machine with the circular knitting machine adopts a weaving machine with a 12-19-inch needle cylinder and 7-10mm latch 1056-1728 needles for weaving.

Preferably, the grey cloth is preshrunk treated before sewing in the step (3), the steaming temperature is 75-85 ℃, and the treatment time is 20-30 s.

Preferably, in the step (4), a weakly acidic dye is selected for dyeing, the pH value of the dyeing is adjusted to 6-7, and the dyeing temperature is 70-90 ℃.

Preferably, in the step (5), the colored sock leg obtained after dyeing is sequentially heated, dried and finished on the inner garment shaping plate; wherein the heating adopts the steaming temperature of 125-135 ℃, and the treatment time is 25-35 s.

Preferably, the set tubular fabric is cut by a cutter, and the sewing thread of each sleeveless underwear is cut by an overlock machine.

The invention also provides the anti-crocheting underwear which is manufactured according to the production process of the anti-loosening anti-crocheting underwear.

Preferably, the anti-dropping underwear comprises one-piece underwear, sleeveless underwear, seven-part sleeve underwear and long-sleeve underwear.

Preferably, the sleeves of the seven-quarter-sleeve underwear and the long-sleeve underwear are knitted by a 7-10mm stitch tongue and a 1056-1728 needle stocking machine.

Compared with the prior art, the invention has the advantages that:

1. firstly, the invention directly adopts a common cylinder loom (the cylinder loom comprises a hosiery machine) to produce the underwear on the premise of not increasing the investment of novel equipment, and manufactures the underwear which can cover wrinkles and spots of the body, compact the skin, ventilate and preserve the heat and can be worn all the year round according to the principle of high quality and low price. Secondly, endow the body with light shaping, and balance the body's curve. Thirdly, endowing the underwear with the functions of preventing snagging and preventing raveling, prolonging the service life of the underwear and further improving the cost performance of the underwear.

2. The textile material prepared by taking 15D-60D anti-raveling spandex as an inner wrapping yarn and FDY/DTY8D-70D chinlon as an outer wrapping yarn has good anti-raveling effect. Wrapping yarns by adopting a high-speed wrapping machine, and preferably selecting the wrapping twist as 1500-1900T/M so as to consider both the melting of spandex in the shaping process and the production stability in the weaving process; the draft ratio is 2.7-3.0, so as to give consideration to good texture and excellent anti-falling performance of weaving; the overfeed rate is adjusted to 93-95% to solve the problem of broken ends in the yarn covering process and the problems of yarn stacking and yarn breaking in the weaving process.

3. The invention preferably carries out balance treatment on the fasciated yarn after the preparation of the fasciated yarn is finished (balance treatment: standing for 24 hours or more according to the process requirement under the condition of balanced temperature and humidity in a balance room, the general temperature is 20-25 ℃, and the relative humidity is 50-60%), the fasciated yarn is balanced, the physical structure of the yarn is more stable, the yarn breakage problem caused in the unwinding process can be effectively reduced, and the weaving is more facilitated.

4. Because the fasciated yarn is sensitive to the environment, the invention preferably weaves under the conditions of 20-25 ℃ and 60-65% of relative humidity, the environmental conditions can ensure the stability of the performance of each part of the fasciated yarn to the maximum extent and reduce the occurrence of filament drawing caused by special setting of twist. The invention further preferably arranges a tension controller in the knitting process, the tension controller is connected with the automatic yarn feeder, and the tension controller is set by a program of the tension controller to act on the automatic yarn feeder so that the rotating speed of the automatic yarn feeder is stabilized at 400-500rpm, thereby controlling the yarn feeding speed and ensuring the grain balance in the knitting process.

5. In addition, the elastic band is sewed at the neckline, the armhole, the waist opening or the thigh opening, and the hitching and fixing sewing lines are tied at the sewing line joints of the elastic band, so as to ensure the firmness of the sewing lines and prolong the service life of the underwear.

6. The textile finished products produced by the hosiery machine comprise various underwear styles such as sleeveless underwear, sleeved underwear, conjoined underwear and the like.
