Description

Technical Field

[0001] The invention belongs to the technical field of embedded composite spinning, and specifically relates to a method for producing high-count seaweed high-proportion blended yarn. Background Art

[0002] Embedded composite spinning technology, namely double filament double roving structure, is a new type of spinning technology derived from the upgraded and iterative yarn structure based on Siro compact spinning, Sirofil spinning and Siro filament composite spinning. This new spinning technology can embed short fibers into the composite yarn body by filaments, effectively combining the advantages of short fibers and filament fibers to form a stable and firm yarn structure. The short fibers are more spinnable and the yarn surface is smooth, which expands new ideas for the design and development of composite functional yarns.

[0003] Embedded composite spinning is mainly achieved by installing and upgrading the filament feeding device on the traditional ring spinning frame, such as Figure 1 As shown. It includes a filament tensioner 5 and a guide wheel 6, which are respectively installed on the yarn guide rod and the cradle; while the short fiber roving 1 and the short fiber roving 2 are fed into the drafting device 8 from the bell mouth 7, the filaments 3 and 4 are fed into the front roller of the drafting device 8 through the filament tensioner 5 and the guide wheel 6 of the cradle, and after the intersection, they are twisted and wound through the winding device 9 to form a bobbin. The main principle of embedded spinning is: it is realized by using the filament and short fiber roving system positioning technology, and the relative positions of two filaments and two short fiber rovings are reasonably arranged on the front roller jaw line, so that the filaments can capture the short fibers well, and the short fiber weak twist whiskers in the spinning triangle area are stably and effectively enhanced.

[0004] Due to the complexity and diversity of the production environment, for workers in special production environments such as oil processing and metal smelting, single-function textiles cannot provide multiple protections. They need to have high-strength, high-flame-retardant, and anti-cutting composite functions to better achieve safety protection in daily production work. Therefore, as a direct factor affecting the performance of textiles, the high-strength, high-flame-retardant, and anti-cutting composite properties of textiles can be achieved through changes in yarn structure to meet the wearing and protection needs of different parts of the body. This is of great significance for the design and development of protective gloves, protective wrist guards, protective knee pads, and protective socks. Summary of the invention

[0013] Preferably, in the pre-opening process, two or more flame-retardant viscose are processed in sequence by a FA002 automatic cotton plucking machine, a FA022-6 multi-bin cotton mixing machine, and an automatic baling machine to obtain a flame-retardant viscose soft bag.

This technical solution analyzes the principle of embedded composite spinning technology and explores the advantages of its structural variation in yarn preparation.

[0026] The specific embodiments of the present invention will be described in detail below. In order to avoid too much unnecessary details, the well-known structures or functions will not be described in detail in the following examples. The approximate language used in the following examples can be used for quantitative expression, indicating that the quantity can be allowed to have a certain change without changing the basic function. Unless otherwise defined, the technical and scientific terms used in the following examples have the same meaning as those generally understood by those skilled in the art to which the present invention belongs.

[0027] 1. Product development 1.1 Raw material selection The seaweed fiber with the specification of 1.45dtex×38mm is selected, with the fiber breaking strength of 3.6cN / detx, breaking elongation of 14.5%, and regain of 20.7%. As an excellent flame-retardant fiber, the limiting oxygen index of seaweed fiber can reach 47.5%, and it has the advantages of natural flame retardancy, antibacterial, skin-friendly and breathable, but the cost is relatively high.

[0028] Taking into account the wearing and economic aspects, the flame retardant viscose is selected with a length of 38mm, a fineness of 1.7dtex, and a fiber breaking strength of 2.1cN / detx. Flame retardant viscose is made by adding sodium silicate flame retardant to ordinary viscose. The limiting oxygen index can reach 32%, and the strength and elongation at break are also improved. The length of aramid 1313 is 50mm, the fineness is 1.7dtex, and the fiber breaking strength is 3.8cN / detx. The limiting oxygen index of meta-aramid 1313 is greater than 28%, and it has strong heat resistance and stability. The heat shrinkage rate at about 250°C is only 1%. It has excellent electrical insulation, radiation resistance, wear resistance and other characteristics. As a flexible polymer material with low stiffness and high elongation, it can be well blended with other fibers.

[0029] The ultra-high molecular weight polyethylene filament is selected with a specification of 75D, an average fiber breaking strength of ≥38cN / detx, and a breaking elongation of ≤4.0%. Ultra-high molecular weight polyethylene fiber will not melt or deform at 200°C, and its specific strength is more than 10 times that of steel wire with the same cross-section. It has the characteristics of corrosion resistance, wear resistance, light resistance, electrical insulation, and impact resistance.

[0030] 1.2 Spinning scheme The present invention adopts the embedded spinning process, and the yarn structure is as follows Figure 2 As shown in the figure, on the front roller jaw line, two filaments F1 and F2 are symmetrically fed into the large triangle area from the outside, and two rovings S1 and S2 are symmetrically fed into the large triangle area from the inside, respectively intersecting with the filaments at C1 and C2, twisting and twisting at point C to form yarn. It can be seen that the filaments wrap and strengthen the short fibers, and then wrap with another wrapped and strengthened yarn, so the short fibers are effectively embedded in the main body of the yarn during the spinning process.

[0031] Compared with Siro compact spinning, Sirofil spinning, and Siro filament composite spinning (such as Figure 3~Figure 5 As shown in the figure, the advantage of the embedded composite spinning technology of the present invention is that two symmetrical reinforcement protection zones are added to the yarn structure, which not only enhances the twisted whiskers in the yarn zone, but also reduces the breakage of the spinning and improves the yarn quality. The spinning method of the present invention can be used to improve the yarn quality and fiber utilization rate, realize the spinning of difficult-to-spin fibers, realize the development of carrier-spun ultra-high count yarns, realize the spinning of high count yarns with low-grade spinning raw materials, and realize the spinning of yarns with multiple colors on ring spinning frames.

[0032] Taking into account the functionality, wearability, spinnability and appearance of the yarn, the yarn blending ratio of seaweed fiber / flame-retardant viscose fiber / aramid fiber 40 / 20 / 40 + ultra-high molecular weight polyethylene filament 75D / 2 was selected, and the yarn count was 30 English.

[0033] Combined with previous spinning production experience, the yarn development strategy is as follows: the pre-opening and pre-mixing process is adopted to achieve the uniform mixing of flame-retardant viscose and seaweed fiber raw materials, and then aramid fiber is incorporated in the drawing process, and polyethylene filament is wrapped in the spinning process; the temperature and humidity of the workshop are fully controlled from the cleaning process to the winding process, and the temperature and humidity differences between different processes are adjusted to maintain the stability of the fiber; in the key processes of yarn formation, high-quality equipment accessories are selected, such as cleaning, carding, spinning and other processes, and related equipment such as carding machines, spinning machines, etc. are transformed to expand the scope of application of the equipment, improve production efficiency, and optimize the yarn quality.

[0034] 1.3 Process flow Pre-opening: two or more flame-retardant viscose → FA002 automatic cotton plucking machine → FA022-6 multi-bin cotton mixing machine → automatic baling machine for baling (flame-retardant viscose soft bag).

[0035] Premixing: flame retardant viscose soft bag + seaweed fiber → FA002 automatic cotton plucking machine → FA022-6 multi-bin cotton mixing machine → automatic baling machine for baling (flame retardant viscose + seaweed fiber soft bag).

[0036] Production: (flame retardant viscose + seaweed fiber soft bag) + (flame retardant viscose soft bag) → FA002 automatic cotton plucking machine → FA036 mixed cotton opening machine → FA201B carding machine → JWF1310 series drawing frame (one-time aramid addition, two-time drawing frame) → Rieter RSBD22C drawing frame (final drawing frame) → FA497 roving frame → JWF1510 spinning frame (wrapped with polyethylene filament) → Savio PolarL automatic winding machine.

[0037] 2. Production points and technical measures 2.1 Pre-spinning process and technical measures Since seaweed fiber is relatively solid, has high moisture regain, high rigidity and low wet strength, it is easy to cause uneven fiber mixing, a large number of cotton knots and short lint, and sticking to rollers and rubber rollers. Therefore, the following technical measures need to be adopted to improve the quality of the yarn: Blowing: A flexible blowing and combing method with short process and light blow is adopted to achieve uniform opening and fine mixing to the maximum extent, reduce mechanical damage to the fiber and reduce the generation of cotton neps.

[0038] Combing: Adopting the concept of flexible combing, with a small combing force, to achieve good combing effect and reduce fiber damage caused by holding and combing. By enlarging the distance from the cylinder to the cover plate, appropriately increasing the cylinder speed and the distance between the licker-in roller and the pre-combing plate, the effect of weakening the combing, fast transfer and reducing the generation of short-staple cotton neps can be achieved.

[0039] Coarse and fine: Adopt the drafting process principle of "large gauge and post-drafting" to reduce the mechanical impact of the fiber. A reasonably proportioned coating is applied on the surface of the roller and rubber roller to reduce the friction between the fiber and the roller and rubber roller, and avoid the occurrence of entanglement and adhesion problems.

[0040] 2.2 Spinning process optimization 2.2.1 Orthogonal experimental design In order to study the influence of the morphological parameters of the twist triangle area of ​​embedded spinning on the yarn properties, three key process parameters that determine the morphology of the twist triangle area were analyzed, including Figure 6 As shown, the length of EF or GH is the distance between the filament and the roving, the length of EH is the distance between the filaments, and the angle α is the angle between the filament and the front roller.

[0041] Then, an orthogonal experiment was designed, as shown in Table 1. The distance between the filament and the roving, the distance between the filaments, and the angle α between the filament and the front roller were set as factors A, B, and C, respectively. The yarn neps (+200) and breaking strength were used as evaluation indicators to optimize the process parameters of the yarn twisting triangle area and find the optimal process configuration.

This is because the angle is a direct factor affecting the overall shape of the twisting triangle. Only a suitable angle can achieve better wrapping of the filament on the staple fiber and reduce the shedding and breakage of the staple fiber. Among them, from the perspective of the optimal process parameter selection, the optimal level combination of +200% cotton knot value is A2B2C3, and the optimal level combination of breaking strength is A1B3C3. After comprehensive comparison and consideration, the optimal factor level combination is A2B3C3, that is, the distance between the filament and the roving is 2mm, the distance between the filament and the filament is 12mm, and the angle between the filament and the front roller is 65°.

In particular, the waxing treatment of the winding can reduce the friction coefficient between the yarn and the mechanical parts, prevent the yarn from being subjected to large mechanical wear during the scraping process, and produce a large number of cotton knots and short lint, which to a certain extent achieves the effect of reducing winding yarn defects and improving yarn strength.

[0044] 3. Product functional testing By adopting embedded composite spinning technology and optimizing yarn process parameters, 30-count yarn of seaweed fiber / flame-retardant viscose fiber / aramid fiber 40 / 20 / 40+ultra-high molecular weight polyethylene filament 75D / 2 was prepared. According to experimental tests, the yarn linear density deviation rate was +0.7%, the linear density variation coefficient was 0.8%, the single yarn breaking strength was 42.2cN / tex, the single yarn breaking strength variation coefficient was 7.4%, the breaking elongation was 3.8%, the twist was 74.3 twists / 10 cm, the uniformity variation number was 10.16%, the fine section (-50%) was 0.5 / km, the thick section (+50%) was 1.5 / km, the cotton knot (+200%) was 12 / km, and the hairiness H value was 2.31. Therefore, the prepared yarn strength was high and the cotton knot per kilometer was small, which laid a good foundation for the subsequent fabric weaving.

[0045] 3.1 Functional Testing (1) Flame retardancy. According to GB / T 8965.1-2020 Flame-retardant Protective Clothing, the flame retardant effect of fabrics made of yarn is tested by Shandong Provincial Textile Product Quality Supervision, Inspection and Testing Center.

[0046] (2) Cutting resistance: According to the EU EN-388 standard for protective gloves against mechanical hazards, the TMD100 cut resistance tester (Nantong Hongda Experimental Instrument Co., Ltd.) was used to test the cut resistance of the fabric.

[0047] (3) Tear resistance: Use the YG028 electronic fabric strength tester, set the test parameters of the strength tester, the clamp distance is 20 cm, the stretching speed is 10 cm per minute, and test the tear strength of the fabric.

[0048] (4) Puncture resistance: Use the YG028 electronic fabric strength tester, set the test parameters of the strength tester, the range is 500N, the steel needle speed is 10cm per minute, and test the puncture resistance of the fabric.

[0049] 3.2 Test Results Comparison Embedded spinning and sirofilament composite spinning were used to prepare 30-ne yarns of seaweed fiber / flame-retardant viscose fiber / aramid fiber 40 / 20 / 40+ultra-high molecular weight polyethylene filament 75D / 2, and sirofil spinning was used to prepare 30-ne yarns of seaweed fiber / flame-retardant viscose fiber / aramid fiber 40 / 20 / 40+ultra-high molecular weight polyethylene filament 150D. Functional tests such as yarn flame retardancy, cut resistance, tear resistance, and puncture resistance were carried out, and the average test results are shown in Table 5. The experimental results show that embedded spinning after optimization of yarn structure process parameters has great advantages in yarn flame retardancy, cut resistance, tear resistance, and puncture resistance compared with sirofilament composite spinning and sirofil spinning, and is suitable for the preparation of high-end functional composite yarns.

The yarn category is seaweed fiber / flame retardant viscose fiber / aramid fiber 40 / 20 / 40+ultra-high molecular weight polyethylene filament 75D / 2, and the yarn count is 30 British count. The research innovations are as follows: (1) Appropriate technical measures were adopted to improve the production process and optimize the spinning process, thus solving the spinning difficulties encountered during the preparation of the yarn. In particular, due to the characteristics of seaweed fiber such as large moisture regain, high rigidity, weak wet strength, and poor cohesion, the fiber mixing was uneven, a large number of short-staple cotton knots were generated, the rollers were entangled, the spun yarn was broken, and the winding yarn defects were caused.

[0051] (2) The optimal yarn structure was found through orthogonal experimental analysis of yarn structure parameters in the spinning process. Functional test experiments were conducted on sirofilament composite spinning and sirofil spinning, further verifying that embedded spinning has great advantages in the preparation of functional composite yarns.

[0052] (3) The structurally variable high-strength, highly flame-retardant and anti-cutting yarn developed by the company has expanded the application field of embedded spinning technology. The unique enhanced functional area of ​​embedded spinning can achieve tight coverage of short fibers by filaments, providing technical support for the preparation of a series of multifunctional differentiated yarns and fabrics. It is also of great significance for the research on structurally variable yarns with composite properties, and can be widely used in fire fighting, industrial protection, aerospace and other fields.
