Description
Technical Field
The invention relates to a double-layer wrapping structure three-component composite yarn with negative poisson ratio, a three-channel ring spinning device and a control method thereof, and belongs to the technical field of spinning.
Background
The negative poisson ratio yarn is a composite yarn with special mechanical properties, and the apparent diameter of the yarn becomes thicker when the yarn is axially stretched so as to generate radial expansion deformation. The negative poisson ratio yarn is generally composed of two components, wherein the first component is generally made of a high-modulus low-elongation fiber material, such as carbon fiber, glass fiber, kevlar fiber, aramid fiber and the like; the second component is a low-modulus high-elongation fiber material, such as siloxane rubber, natural rubber or spandex filament, and the like. The two materials are used for spinning the double-component composite yarn with the double-spiral structure, under the condition of low tensile tension, the second component is in a straight line shape to form the core yarn of the composite yarn, the first component is spirally wrapped with the second component to form the wrapping yarn 1 of the composite yarn, and at the moment, the first component (with high modulus, small elasticity, low elongation and large occupied ratio) wraps the second component (with low modulus, large elasticity, high elongation and small occupied ratio) to form the wrapping structure composite yarn. Under high tensile conditions, the first component is drawn straight into a core yarn portion of the composite yarn and the second component is wound on the core component in a spiral form into a wrapped yarn 1 of the composite yarn. The yarn undergoes structural inversion under the action of the stretching tension to lead the diameter of the yarn to be changed from (2*d) 0 +D 0 ) Direction (2*D) 0 +d 0 ) And thus a negative poisson's ratio effect. The composite material with the negative poisson ratio effect can be prepared by utilizing the negative poisson ratio yarn, and a new subject is provided for the development of textile materials, so that the method has great theoretical significance.
The composite yarn is especially one formed by twisting drawn staple fiber sliver and filament yarn, and the spun staple fiber sliver and filament yarn may form yarn structure with doubling, covering, wrapping, winding, etc. Based on the mechanical properties of filaments, staple/filament composite yarns can be divided into three categories: (1) a short fiber/elastic filament composite yarn formed by compositing spandex and short fibers; (2) a staple fiber/flexible filament composite yarn formed by compositing polyester filaments and staple fibers; (3) a spun/rigid filament composite yarn formed by combining stainless steel filaments and staple fibers. According to the structure and yarn forming process of the composite yarn, the method can be divided into: (1) staple/filament doubling; (2) staple/filament intertwisted spun yarn 1: plug Luo Feier (silrofil) yarn; (3) filament/staple hybrid twisted yarn; (4) staple/filament core spun yarn; (5) staple/filament wrap yarns.
The negative poisson ratio yarn generates structural phase transformation under the action of tensile force, and the common composite yarn does not have the structural phase transformation capacity, so that the negative poisson ratio mechanical effect is avoided. Therefore, how to configure the modulus, elongation, proportion of the two components of the composite yarn and optimize the structure of the negative poisson's ratio yarn is a key technology for producing the negative poisson's ratio yarn.
The hong Kong university Hu Gong patent, "a negative poisson's ratio yarn structure and method of making same (CN 201210212844.3)" discloses a negative poisson's ratio yarn structure and method of making same, the negative poisson's ratio yarn structure being formed by twisting a first yarn and a second yarn, the first yarn having a tensile modulus greater than that of the second yarn. The patent "a three-axis cone-type composite spinning device and method for negative poisson's ratio yarn (CN 201710539952.4)" of the university of eastern hua Yu Weidong provides a three-axis cone-type composite spinning device and method for poisson's ratio yarn. The Donghua university Yu Weidong patent "a ring spun negative poisson ratio yarn and its composite spinning apparatus, method and use (CN 201710539986.3)" provides a ring spun negative poisson ratio composite structure yarn made up of relatively rigid, overwrapped filament bundles and relatively flexible, staple fiber strands in the yarn core by direct asymmetric two-axis composite spinning on a ring spinning frame.
The size of the negative poisson ratio coefficient has important significance for preparing the material with the negative poisson ratio coefficient, and the preparation of the yarn with high negative poisson ratio needs innovative design in the links of material selection, yarn structural design, composite yarn forming process and the like. The negative poisson ratio yarn prepared by the current production has the defects of small negative poisson ratio coefficient, insensitive response, irreversibility and the like due to the limitations of the negative poisson ratio yarn in the aspects of material selection, composite structure design, spinning process manufacturing and the like. The method comprises the following steps:
1. In material selection of negative poisson's ratio yarns
Currently, mainly from the viewpoint of increasing the modulus difference between the two components, the first component (wrapping component at low tension) is usually selected as a high modulus low elongation material, and the second component (core component at low tension) is usually selected as a low modulus high elongation material. In practice, except controlling the modulus difference of the two components, the fiber material with the characteristics of high shrinkage, self-curling and the like, the temperature-sensitive shape memory fiber material and the like are optimally selected as the second component material, and the deformation coordination of the first component and the second component is better matched within a specific tensile load or rated tensile strain range, so that the smooth transition of the structural phase of the composite yarn and the full expression of the negative poisson ratio performance are ensured.
2. In the structural design of negative poisson ratio yarns
Based on a two-phase structure model of the two-component yarn, under the condition of low tensile tension, the second component linearly forms a core component of the composite yarn, and the first component is spirally wound on the first component to form a wrapping component of the composite yarn; under high tension, the first component is drawn straight to form a core component of the composite yarn, the second component is wound on the core component in a spiral form to form a sheath component of the composite yarn, and the yarn diameter is changed from (2*d) 0 +D 0 ) Direction (2*D) 0 +d 0 ) A negative poisson's ratio effect is produced, but during the structural phase transition phase separation occurs due to lack of restraint between the two components, rendering the phase structural transition irreversible.
3. Technical aspect of spinning yarn with negative poisson ratio coefficient change
In the process of preparing the negative poisson ratio composite material, the negative poisson ratio coefficient is changed along the length direction of the yarn according to different structural and functional requirements, and the yarn with the changed negative poisson ratio coefficient cannot be spun by the prior art.

regulating and controlling the linear density rho of the three-component composite yarn according to actual needs hy (t) the short fiber component mixing ratio K y (t) the mixing ratio of the rigid filaments to the elastic filaments is K x1 (t)、K x2 And (t) realizing the controllable change of the negative poisson ratio coefficient of the composite yarn, and achieving the purpose of designing the negative poisson ratio coefficient of the composite yarn according to actual needs or regulating and controlling the negative poisson ratio coefficient of the composite yarn to change according to a specified rule.
The three-channel ring spinning device and the control method designed as described above are applied to practical applications, such as the following first and second embodiments.
Example one, as shown in table 1 below, uses high-modulus low-elongation rigid filaments such as metal filaments, glass filaments, carbon fiber filaments, etc. as the wrapping yarn 1 (first component of the negative poisson ratio composite yarn) of the double-wrapped composite yarn, and the ratio is less than 15%; the core yarn (the second component of the negative poisson ratio composite yarn) of the double-package intertwining composite yarn is selected from the group consisting of the crimped staple fiber, the high-yield staple fiber, the high-fluffing staple fiber, the cotton, the wool and the mixed fiber thereof, and the ratio of the core yarn is more than 70 percent.

Let the diameter of the first component (wrap yarn 1) be d 1 The diameter of the second component (core yarn) is D, and the diameter of the third component (wrapping yarn 2) is D 2 Take d= (d 1 +d 2 )/2.

The negative poisson's ratio coefficient of a typical yarn is positively correlated with the rate of change epsilon of diameter. If it isThe negative poisson's ratio coefficient is large if the difference value (D-D) between the diameters of the first component yarn and the second component yarn is increased, and is small if the difference value (D-D) between the diameters of the first component yarn and the second component yarn is decreased.

The method comprises the following specific steps:
speed V of rear roller is regulated and controlled through asynchronous drafting mechanism h1 (t)、V h2 And (t) controlling the linear density and diameter variation of the second component yarn (core yarn).
If the raw material of the core yarn (the second component) is selected from the crimped fiber to produce the roving with the fixed weight of 4.6 g/10 m, the wrapping yarn 1 (the first component) is selected from the stainless steel filaments with the diameter of 33 mu/1 f, the wrapping yarn 2 (the second component) is selected from the spandex filaments with the diameter of spandex of 55dex/1f, and the twisting coefficient of the composite yarn is 320, and the spinning machine provided by the patent is used for spinning.
