Description

Technical Field

[0001] The utility model relates to the technical field of knitted fabrics, and particularly relates to a double-sided fabric with a super-soft and warm vertical-strip needle-dropping structure. Background Art

[0002] With the improvement of people's living quality, the quality requirements for clothing are also getting higher and higher, especially for the requirements of close-fitting fabrics, and people pursue more softness and comfort. There are various traditional fabrics on the market, but they cannot meet all people's needs. Some have a soft touch but poor warmth retention; some have strong warmth retention but lack in terms of touch. Therefore, it is very important to research a close-fitting fabric that has both softness and warmth retention. Content of the Utility Model

[0003] To achieve the above object, the technical solution of the utility model is a double-sided fabric with a super-soft and warm vertical-strip needle-dropping structure, which combines a fully-cotton super-soft low-twist yarn and Lycra spandex for the organizational structure design. The vertical-strip needle-dropping double-sided fabric is formed by the knitting needles of the upper needle cylinder and the lower needle cylinder. The knitting needles of the upper needle cylinder and the lower needle cylinder both take two sections as a cycle and two tracks as a complete organization, and the arrangement order of the two tracks is composed of two weaving structures, namely the float stitch and the loop stitch.

[0004] As a further description of the utility model, the arrangement order of the first track successively includes a loop stitch, a float stitch, a float stitch, and a loop stitch; the arrangement order of the second track successively includes a float stitch, a loop stitch, a loop stitch, and a float stitch; the lower needle cylinder drops needles in the 13th, 14th, 17th, and 18th tracks, and 18 tracks form a cycle.

[0005] As a further description of the utility model, the yarn specification of the fully-cotton super-soft low-twist yarn is 14.76 tex (40S), and the yarn specification of the Lycra spandex is 3.33 tex (30D).

[0006] Its beneficial effects are as follows:

[0007] 1. By combining a fully-cotton super-soft low-twist yarn and Lycra spandex for the organizational structure design, the vertical-strip needle-dropping double-sided fabric is designed into a double-sided organizational structure with needle-dropping on the front side and normal on the back side, with a unique structure and novel design. A super-soft low-torque yarn with lower twist, fewer feathers, and higher strength is used, and Lycra spandex is added, making the fabric more elastic; a double-sided raising treatment is performed in the dyeing and finishing process, making the fabric skin-friendly, breathable, soft, comfortable, and warm, and still maintaining good performance after multiple washes.

[0008] 2. The organizational structure is double-sided fabric. The cams on the upper dial are arranged in the order of B and A, with two segments forming a cycle. The cams on the lower cylinder are arranged in the order of A and B, with two segments forming a cycle. The weaving process uses all-cotton super-soft low-torque yarn, with a coil length of 3.1 mm, that is, the yarn length is 310 mm for 100 needles; the spandex is fully loaded on a single layer, with a coil length of 0.8 mm, that is, the yarn length is 80 mm for 100 needles. In the knitting process, the number of oil needles should be reduced and the tension of each fed yarn should be adjusted to make the tension uniform.

[0009] 3. The vertical-strip needle-dropping double-sided fabric obtained by the present utility model is soft and comfortable, has a rich texture, and strong warmth retention. During the post-treatment process, double-sided raising treatment is carried out to form a short fluff layer on its surface, which has good softness and warmth retention. Therefore, this knitted fabric is a double-sided fabric with a super-soft warmth-retention vertical-strip needle-dropping structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] With the improvement of people's living quality, the quality requirements for clothing are also getting higher and higher, especially for the requirements of next-to-skin fabrics, and people pursue more softness and comfort. There are a variety of traditional fabrics on the market, but they cannot meet all people's needs. Some have a soft handfeel but poor warmth retention; some have strong warmth retention but lack in terms of handfeel. Therefore, the present utility model provides a double-sided fabric with a super-soft warmth-retention vertical-strip needle-dropping structure by using knitting process and dyeing and finishing process.

[0015] The all-cotton super-soft low-twist yarn used for the underwear fabric has a yarn specification of 14.76 tex (40S), with super-soft characteristics, lower twist, fewer feathers, and higher strength; the yarn specification of Lycra spandex is 3.33 tex (30D), and the spandex proportion reaches 6%, with greater elasticity. The dyeing and finishing process performs double-sided raising treatment, making the fabric skin-friendly, breathable, soft, comfortable, and warm, and still maintaining good performance after multiple washes.

[0016] I. Knitting Process

[0017] 1. The knitting equipment model is Baiyuan BYJM20 double-sided circular weft knitting machine, with a gauge of 28 needles / 25.4 mm, a cylinder diameter of 864 mm (34″), 30 needle cylinders, 72F courses, a total of 2,976 needles. During the weaving process, better knitting needles are selected to avoid defects such as horizontal stripes and needle marks. At the same time, the machine is kept clean, the number of oiled needles is reduced, and the tension of each fed yarn is adjusted to make the tension uniform.

[0018] 2. In the knitting needle arrangement, the needle plate and the needle cylinder adopt a double-sided needle matching method. There are two tracks on the upper needle plate, that is, two sections. The knitting needles are arranged in the order of A and B, and two sections form a cycle; there are two tracks on the lower needle cylinder, that is, two sections. The knitting needles are arranged in the order of A and B, and two sections form a cycle; each section forms a cycle with eighteen courses to complete the knitting of the smallest pattern.

[0019] 3. The cam arrangement is as shown in Table 1 below:

[0020] Table 1 Cam Arrangement Table

[0021]

[0022] Note: ∧. Knitting cam; -. Float cam

[0023] It can be seen from Table 1 that the knitting needles on the upper needle plate and the lower needle cylinder both take two sections as a cycle, and eighteen courses form a complete weave. The arrangement order of the eighteen courses is composed of two weaving structures: float weave and knitting weave. The arrangement order of the first course includes knitting weave, float weave, float weave, and knitting weave in sequence; the arrangement order of the second course includes float weave, knitting weave, knitting weave, and float weave in sequence; on the 13th, 14th, 17th, and 18th courses, the needles on the lower needle cylinder are withdrawn.

[0024] 4. The knitting pattern is as shown in the appendix Figure 1 as follows.

[0025] 5. Warp threading method: For 1F, both a 14.76 tex (40S) all-cotton super soft low-twist yarn and a 3.33 tex (30D) Lycra spandex are threaded simultaneously; for 2F, only the 14.76 tex (40S) all-cotton super soft low-twist yarn is threaded alone.
