Embodiment 1
[0046] Disclosed in this example figure 1 In the shown composite structure core-spun yarn, a ring-spun composite core-spun yarn spinning device is adopted; the ring-spun composite core-spun yarn spinning device includes a ring spinning machine platform and a spandex core-spun yarn spinning device;
[0047] Along the processing direction of the yarn, the ring spinning machine table sequentially includes a feeding part, a drafting part and a twisting and forming mechanism; the drafting part includes a rear roller and a rear top roller 4 matched with the rear roller, and Roller and the upper and lower pins 5 matched with the middle roller and the front roller and the front top roller 6 matched with the front roller; along the processing direction of the yarn, the spandex core-spun yarn spinning device successively includes a core yarn tension roller 10 and a guide roller Wire Part 9.
[0048] Such as figure 1 As shown, according to the above technical solution, the spandex core...
Embodiment 2
[0073] The blue cotton is made into blue pure cotton roving sliver A through blending, cleaning, carding, doubling, sliver coiling, combing, drawing and roving. The roving weight is 8.0g / 10m. The factor is 110.
[0074] The white elastic polyester fiber is processed into cotton blending, cleaning, carding, drawing, and roving to make elastic polyester roving sliver B, the weight of the roving is 3.0g / 10m, and the twist coefficient is 60; the elastic polyester fiber The fiber length was 38 mm, and the fiber elongation at break was 25%.
[0075] The core silk is made of 70D spandex.
[0076] On the modified ring spinning frame, the blue cotton roving sliver A is fed from the double-hole bell-mouth wide channel a, and the white elastic polyester roving sliver B is fed from the double-hole bell-mouth wide channel b; the spandex silk cake Place it on two core wire tension godet rollers, set the draft at 3.5 times, the spandex core wire C meets the drafted A and B whiskers at the ...
Embodiment 3
[0079] The proportion of 60wt% cotton 40wt% tencel white staple fiber is respectively processed through the processes of blending, cleaning, carding, doubling, sliver rolling, combing, drawing, and roving to produce white tencel cotton roving strand A. The basis weight of the roving is 7.0g / 10m, and the twist coefficient is 85.
[0080] The white nylon fiber is processed into cotton blending, cleaning, carding, drawing, and roving to produce white nylon roving sliver B. The weight of the roving is 3.5g / 10m, and the twist coefficient is 60; the length of the nylon fiber is 38mm, The fiber elongation at break was 30%.
[0081] The core silk is made of 40D spandex.
[0082] On the modified ring spinning frame, the white Tencel cotton roving sliver A is fed from the double-hole bell-mouth wide channel a, and the white nylon roving sliver B is fed from the double-hole bell-mouth wide channel b; the sliver B is placed in In the middle of A; the spandex yarn cake is placed on the t...
