[0049] The first and second tracks are elastic connecting yarn 2; the third track is soft inner yarn 3, and the fourth track is thick outer yarn 1.

[0050] The super-soft-touch knitted fabric with a thick needle gauge for woolen sweaters according to the present invention is interrelated and acts together through a special knitting structure and triangular arrangement. First, it gives the thick outer layer a strong fluffiness and a soft and comfortable hand feeling; second, it gives the soft inner layer a skin-friendly and smooth effect; third, it gives the fabric the performance of anti-pilling.

[0051] Specifically, the thickness of the thick outer yarn 1 is 10 - 20 NMT; the thickness of the elastic connecting yarn 2 is 30 - 100 D; the thickness of the soft inner yarn 3 is 15 - 40 S.

[0052] Specifically, the length of the thick surface yarn 1 is 28 - 30 cm / 50 needles; the length of the elastic connecting yarn 2 is 22 - 24 cm / 50 needles; the length of the soft inner yarn 3 is 14 - 16 cm / 50 needles.

[0053] Specifically, the imitation woolen sweater thick needle gauge super soft touch knitted fabric has a knitting structure of two needle beds on the upper needle plate and two needle beds on the lower needle cylinder.

[0054] The inner layer is knitted on the upper needle plate with a fine needle gauge; the surface layer is knitted on the lower needle cylinder with a thick needle gauge.

[0055] Specifically, the upper needle plate and the upper needle plate are knitted in a staggered cycle of high and low needles.

[0056] Specifically, the thick surface yarn 1 is a polyester yarn, the elastic connecting yarn 2 is a spandex yarn and / or a polyester yarn, and the soft inner yarn 3 is a cotton yarn and / or a blended cotton yarn with staple fiber.

[0057] In the second aspect of the present invention, a method for preparing an imitation woolen sweater thick needle gauge super soft touch knitted fabric is proposed, characterized in that the method for preparing the imitation woolen sweater thick needle gauge super soft touch knitted fabric is used to prepare any one of the imitation woolen sweater thick needle gauge super soft touch knitted fabrics described above, and the method for preparing the imitation woolen sweater thick needle gauge super soft touch knitted fabric includes the following steps:

[0058] S1. Yarn preparation;

[0059] S2. Grey fabric weaving;

[0060] S3. Grey fabric dyeing;

[0061] S4. Fabric after-treatment.

[0062] Specifically, in step S3, the grey fabric dyeing includes the following steps: S31. Pretreatment; S32. Dyeing; S33. Discharging from the vat.

[0063] In step S31, the pretreatment is to carry out singeing treatment, scouring and bleaching treatment and ultrasonic treatment on the fabric grey fabric in sequence.

[0064] Specifically, for the singeing treatment: using the principle that the temperature rising rate of the cloth body and the fluff is different, singeing is carried out by a gas singeing machine in a double-sided singeing mode, and the singeing process parameters are a machine speed of 60 - 80 m / min and a firepower of 25 - 28 cubic meters per hour.

[0065] The singeing treatment makes the obtained fabric anti-pilling on the one hand; and makes the fabric not shed fluff on the other hand.

[0066] Specifically, for the scouring and bleaching treatment, the grey fabric is put into the bath solution, and a scouring and bleaching formula is added to the bath solution: 2 g / L of refining enzyme, 0.2 g / L of caustic soda, H2 O 2 8 g / L, activator 2 g / L, anti-wrinkle agent 1 g / L, softener 2 g / L, and then heat the bath solution added with the above scouring and bleaching formula to 90 - 100 °C and keep it warm for 30 min. The pH value of caustic soda ≥ 13, and the scouring enzyme mainly includes scouring agent, H 2 O 2 stabilizer, water softener, degreasing agent, alkali and enzyme agent. The pH value of the scouring enzyme is 11 ± 1, which is milder than that of caustic soda.

[0067] Adopt a reasonable and mild scouring and bleaching formula. While removing impurities, wax, ash and cottonseed hulls in the fabric fibers, minimize the loss of the fabric fibers themselves, maximize the fabric profit, and at the same time avoid affecting the properties such as the fastness of the fabric due to excessive fiber loss.

[0068] After scouring and bleaching treatment, first, the loss of the fabric itself is reduced to the minimum; second, it is beneficial to the efficiency and color fastness of subsequent dyeing of the fabric; third, it is beneficial to improve the softness of the fabric; fourth, the fabric is not easy to wrinkle.

[0069] The ultrasonic treatment is to wash the greige fabric after scouring and bleaching twice. When washing, add a reducing agent treatment solution and carry out ultrasonic treatment for 5 - 10 min at 50 - 60 °C. The bath ratio is 1:15 - 20, the frequency of the ultrasonic wave is 60 - 70 kHz. After the second ultrasonic treatment, add polyvinyl alcohol and keep it at room temperature for 6 - 8 min, and then wash and dry.

[0070] The etching effect of the ultrasonic treatment has a certain destructive effect on the rough surface layer yarn 1. First, the friction effect of the rough surface layer yarn 1 is reduced, and the anti-crochet hair effect is significant; second, the bulkiness of the rough surface layer yarn 1 is significantly improved; third, the fabric is endowed with the property of anti-pilling.

[0071] In step S31, the fabric greige is subjected to singeing treatment, scouring and bleaching treatment and ultrasonic treatment in sequence. The singeing treatment, scouring and bleaching treatment and ultrasonic treatment are interrelated and act together. First, the friction effect of the rough surface layer yarn 1 is reduced, and the anti-crochet hair effect is significant; second, the bulkiness of the rough surface layer yarn 1 is significantly improved; third, the fabric is endowed with the property of anti-pilling; fourth, it is beneficial to improve the softness of the fabric; fifth, the fabric is not easy to wrinkle; sixth, it is beneficial to the efficiency and color fastness of subsequent dyeing of the fabric.

[0072] In step S32, when dyeing, the fabric greige is dyed, and the temperature is set at 60 - 80 °C when dyeing cotton.

[0073] Specifically, in step S4, the fabric post-treatment includes the following steps:

[0074] S41. Softening treatment;

[0075] S42. Drying;

[0076] S43. Setting on a stenter.

[0077] Specifically, in step S41, when performing the softening treatment, the dosage of the softening agent is 10 - 15 g / L.

[0078] Specifically, in step S42, the fabric greige is vibrated and dried, the drying speed is 15 m / min, and the drying temperature is 130 °C.

[0079] Specifically, in step S43, the setting temperature on the stenter is 130 - 170 °C.
