Embodiment 1

[0012] Cotton roving and nylon filament yarn are selected as spinning raw materials, raw materials A and D are nylon filament yarn, B and C are cotton roving, and the air negative pressure applied is 0.15Mpa. The test results of the yarn obtained after spinning on the spinning frame are shown in Table 1.

Embodiment 2

[0014] Cotton roving and nylon filament yarn are selected as spinning raw materials, raw materials A and D are nylon filament yarn, B and C are cotton roving, and the air negative pressure applied is 0.20Mpa. The test results of the yarn obtained after spinning on the spinning frame are shown in Table 1.

Embodiment 3

[0016] Cotton roving and nylon filament yarn are selected as spinning raw materials, raw materials A and D are nylon filament yarn, B and C are cotton roving, and the air negative pressure applied is 0.25Mpa. The test results of the yarn obtained after spinning on the spinning frame are shown in Table 1.

[0017]

[0018] Through the statistical comparison of the three implementations, it is found that under the condition of negative air pressure of 0.20Mpa, the standard deviation of evenness (CV%), hairiness index (H) and strength index of the obtained product reach relatively ideal indexes.

[0019] Different from conventional methods, the invention has obvious effects on fibers with small initial modulus and fibers with large initial modulus.

Abstract

The invention provides a spinning method for high-count high-quality embedded compact spun yarn. Filament yarn and short fiber rough yarn can be spun, the quantity of harmful hairiness can be effectively reduced, and the resultant yarn quality can be improved. The spinning method includes the following steps that two pieces of short fiber rough yarn are placed in the middle, two pieces of filament yarn are distributed at the two sides of the short fiber rough yarn respectively, the four pieces of yarn are divided into two groups, and each group comprises one piece of short fiber rough yarn and one piece of filament yarn; when the four pieces of yarn pass through a horizontal line of a front jaw of a drawing roller, downward air negative pressure is added below a twisting trigonum plane in the opposite direction; one pair of filament yarn and short fiber rough yarn are twisted in a first twisting trigonum, and the other pair of short fiber rough yarn and filament yarn are twisted in a second twisting trigonum; the semi-finished product yarn after being twisted in the first twisting trigonum and the second twisting trigonum enters a third twisting trigonum and is twisted through a steel collar bead ring. The air negative pressure ranges from 0.15 Mpa to 0.3 Mpa.

Description

technical field [0001] The invention relates to a spinning method of high-count and high-quality embedded compact spinning yarn, which belongs to the field of textile processing. Background technique [0002] The embedded spinning method is a technological innovation based on the traditional ring spinning method. This innovation makes the short fibers constrained by the filaments during the spinning process, and there are fewer floating unconstrained fibers, so that from the source The formation of yarn hairiness is reduced. However, there will still be some harmful hairiness greater than 3mm formed by fibers that are not well restrained, especially when the length of the fiber is longer or the initial modulus of the fiber is higher, the number of unconstrained fibers will increase, 3mm The number of harmful hairiness will increase significantly, which will have a certain adverse effect on the physical indicators such as yarn evenness and strength.
