Description

Technical Field

[0001] This application relates to the field of textile technology, and in particular to a pure wool single warp and single weft seroffier fabric and its preparation process. Background Technology

[0002] The worsted fabric industry continues to develop, with pure wool worsted fabrics gaining significant attention for their high-end quality and functionality. Pure wool worsted fabrics, produced through a combing process, excel in warmth, comfort, and durability, and are widely used in various high-end apparel and home textile products, bringing a high-quality experience to people's lives and driving the development of related industries. At the same time, the development of worsted fabrics has also spurred continuous progress in textile technology, playing a positive role in the industrial upgrading and product innovation of the entire textile industry.

[0003] In the past, the industry routinely employed traditional spinning and weaving processes to produce high-quality fabrics. For worsted wool fabrics, wool raw materials were typically used directly, spun into yarn through ordinary spinning processes, and then woven. This method can guarantee the basic properties of the fabric to a certain extent, but it has limitations in improving specific properties. In addition, some improved spinning technologies have been applied, but these technologies often focus on improving one aspect of performance and cannot comprehensively solve the multiple problems existing in the fabric. For example, some technologies may be effective in improving the anti-pilling properties of the fabric, but their effect on reducing fuzz and improving yarn evenness is not significant.

[0004] However, existing technologies have significant drawbacks. Traditionally produced worsted wool fabrics are prone to deformation and pilling, affecting their appearance and lifespan; noticeable fuzz not only reduces the fabric's hand feel and comfort but also its overall aesthetic appeal; and the unevenness of the yarn count results in inconsistent fabric quality, failing to meet the demands of the high-end market for high-quality fabrics, thus requiring improvement. Summary of the Invention

[0005] To improve the performance of all-wool worsted fabrics, this application provides an all-wool single-warp single-weft seroffier fabric and its preparation process.

[0006] This application provides a pure wool single-warp single-weft seroffier fabric and its manufacturing process, using the following technical solution: Firstly, this application provides a pure wool single-warp single-weft seroffier fabric, using the following technical solution: A pure wool single-warp single-weft serofir fabric is woven from serofir yarn, the yarn comprising a core yarn and a cover yarn, the core yarn and cover yarn being made of wool into pure wool single yarn, the pure wool single yarn being treated with a finishing agent comprising the following components in parts by weight: 1-1.5 parts of nanocellulose 5-7 parts of bifunctional polyether silicone oil 0.3-0.5 parts of graphene oxide Crosslinking agent 1.2-1.8 parts 2-3 parts of repair agent 0.5-1 part buffer Add water to make up to 100 servings; The bifunctional polyether silicone oil is prepared using the following steps: Hydrogen-terminated silicone oil and solvent were mixed, and a catalyst was added under a protective atmosphere. Boc-L-allylglycine was added, and the mixture was heated and stirred. Allyl glycidyl ether was added, and the mixture was heated and stirred. After cooling, amino protection was removed, and the mixture was purified to obtain bifunctional polyether silicone oil.

[0007] The yarn produced using the Serofil technology reduces yarn hairiness, resulting in a more even yarn. Nanocellulose forms a dense protective layer on the surface of wool fibers, which, combined with the layered structure of graphene oxide, fills fiber gaps and enhances interfacial bonding, improving the bond between the core yarn and the cover yarn. This helps reduce yarn hairiness and improves abrasion resistance. Bifunctional polyether silicone oil crosslinks with the fibers through its reactive groups. While maintaining the natural fluffiness of wool, its polyether segments enhance hydrophilicity, maintaining the fabric's breathability, while the siloxane skeleton gives the fabric a lasting smooth feel. The crosslinking agent promotes the formation of a stable three-dimensional network among the components, and together with the repairing agent, it fills in micro-damage to the fibers, resulting in more even yarn and improved pilling resistance. The buffer maintains the stability of the treatment environment, ensuring that functional substances act evenly on the fibers. This multi-mechanism synergy allows the fabric to maintain the inherent advantages of wool while achieving performance improvements. The fabric has excellent anti-pilling, abrasion resistance, and breathability, while also having a soft and comfortable feel.

[0008] Preferably, the mass ratio of the end-hydrogenated silicone oil, Boc-L-allylglycine, and allyl glycidyl ether is 1:0.04:(0.02-0.03).

[0009] The hydrogen-containing silicone oil reacts with Boc-L-allylglycine in the above ratio to form an intermediate with both amino and carboxyl groups. Then, epoxy groups are introduced through quantitative allyl glycidyl ether, so that the amino and epoxy groups on the final polymer molecular chain achieve balanced coordination. This structure allows the silicone oil to form a flexible cross-linked network on the fiber surface. The amino groups enhance the binding force with the wool fibers, thereby reducing hairiness. The epoxy groups and other components in the finishing agent produce moderate cross-linking to enhance abrasion resistance. At the same time, the retained polyether long chains maintain the mobility of molecular chain segments, which not only avoids the fabric hardening caused by excessive cross-linking, but also reduces the shear damage to the fibers by external forces through elastic buffering, and synergistically improves anti-pilling and evenness. The spatial arrangement characteristics of the siloxane skeleton and polyether chains keep the breathable channels open in the fabric with a fluffy and soft feel.

[0010] Preferably, the nanocellulose is prepared by modification using the following steps: Nanocellulose was added to water, sonicated, and then a quaternary ammonium salt modifier was added. The mixture was heated and stirred to react, sonicated again, centrifuged, precipitated, and dried to obtain modified nanocellulose.

[0011] By grafting quaternary ammonium salt molecules onto the surface of nanocellulose, stronger affinity and dispersion stability are achieved at the fiber interface. The cationic groups on the modified nanocellulose surface form electrostatic attraction with the negatively charged regions on the wool fiber surface, promoting its directional adsorption and uniform spreading on the yarn surface. This dense and orderly coating layer effectively fills the micro-cracks on the fiber surface, reducing the tendency for fuzz to detach during processing. At the same time, the modified nanocellulose is more easily and uniformly dispersed in the aqueous treatment system, avoiding the aggregation of unmodified particles, allowing it to penetrate more completely into the interlacing points inside the yarn. Through physical reinforcement, it enhances the cohesion between fibers, thereby improving yarn evenness and inhibiting fiber slippage during friction, synergistically improving anti-pilling and abrasion resistance. The surface modification does not change the porous structure of the nanocellulose itself. The micro-channels formed by its directional arrangement, together with the natural scale layer of wool, maintain the moisture permeability and breathability of the fabric. The uniformly distributed nanoparticle layer reduces fiber friction resistance while synergistically maintaining the inherent elastic space of wool, giving the fabric a soft and fluffy feel.

[0012] Preferably, the mass ratio of the nanocellulose to the quaternary ammonium salt modifier is 1:(0.25-0.35).

[0013] The nanocellulose modified according to the above mass ratio can effectively improve the evenness of yarn, reduce hairiness, and thus improve the anti-pilling and abrasion resistance of the fabric, maintain good breathability, and give the fabric a soft and fluffy feel.

[0014] Preferably, the graphene oxide is prepared by modification using the following steps: Graphene oxide was added to water, sonicated, and then ferric chloride and zinc chloride were added. Ammonia was added under heating and stirring conditions to adjust the pH to neutral. After the reaction, the mixture was centrifuged, washed, and dried to obtain dual-ion modified graphene.

[0015] Iron and zinc ions form a co-precipitation network under the control of ammonia water, which coordinates and bonds with oxygen-containing groups on the surface of graphene oxide sheets, causing the sheets to curl moderately and load metal oxide particles. This structure enables the modified graphene oxide to form a three-dimensional adhesion layer with a micro-arching effect on the fiber surface. The curled sheets penetrate deep into the root of the fiber hairs through physical anchoring, which enhances the bonding force and helps the hairs lie flat and the yarn evenness. The metal oxide particles act as hard support points to improve local anti-friction performance, while the staggered stacking between the curled sheets forms breathable microchannels. This structure forms a rigid-flexible interfacial protective layer with the flexible segments of polyether silicone oil in the finishing agent, which improves anti-pilling properties while avoiding excessive fiber adhesion and maintaining the fluffy and soft touch characteristics of the fabric.

[0016] Preferably, the dual-ion modified graphene is prepared by the following steps after modification treatment: The dual-ion modified graphene was added to a solvent, sonicated, and then aminosilane was added. The pH was adjusted to acidic, and the mixture was heated under reflux. After centrifugation, washing, and drying, the modified graphene was obtained.

[0017] Aminosilanes form covalent bonds with the surface of dual-ion modified graphene. While maintaining the three-dimensional arch bridge effect formed by metal ion modification, the steric hindrance of long-chain alkyl groups reduces the stacking density of the sheets, making the graphene more uniformly dispersed in the fiber gaps. The grafted amino groups also enhance the reactivity with polyether silicone oil in the finishing agent, forming a sheet composite encapsulated by a continuous organosilicon phase. This composite reduces fiber friction damage by buffering external force impacts through flexible chain segments, while the dispersed sheet network forms multi-level anchoring points at the root of the fibers to enhance the adhesion effect, synergistically improving anti-pilling and evenness. At the same time, the micro-cell structure formed by the grafted chains maintains the fabric's breathability channels, and the elastic matching between the organosilicon phase and the wool scales maintains the fabric's fluffy feel.

[0018] Preferably, the mass ratio of the dual-ion modified graphene to aminosilane is 1:(0.2-0.3).

[0019] Modification treatment according to the above mass ratio can effectively further improve abrasion resistance and anti-pilling properties, while maintaining the fabric's fluffy and soft feel and good breathability.

[0020] Preferably, the crosslinking agent includes aziridine crosslinking agent.

[0021] Preferably, the repair agent comprises sericin and keratin.

[0022] Secondly, this application provides a manufacturing process for a pure wool single-warp single-weft seroffier fabric, employing the following technical solution: A manufacturing process for a pure wool single-warp single-weft seroffier fabric includes the following steps: S1. The wool tops are treated with a finishing agent to make (78-82) / 1 pure wool single yarn; the wool tops are directly made into (58-62) / 1 pure wool single yarn, and the (58-62) / 1 pure wool single yarn is treated with a finishing agent after winding. S2. Using (78-82) / 1 pure wool single yarn as the core yarn and (58-62) / 1 pure wool single yarn as the outer covering yarn, the yarn is spun by Selofir with a draft ratio of 0.9-1.1, a speed of 8000-9000 rpm, and a twist of 750-850 TPM to obtain a (32-36) / 1 yarn. S3, woven with a 4-end twill weave, yielding 200-210 g / m². 2 raw fabric; S4. Finish the finished fabric by boiling (83-87℃)*(18-22m / min) → washing and shrinking (38-42℃)*(airflow 60-80%) → boiling (78-82℃)*(18-22m / min) → drying machine width (150-154cm)*(overfeed 10-20%) → brushing the finished fabric → special finishing: machine width (148-152cm)*(overfeed 10-20%)*(23-27m / min)*add anti-pilling agent (1.8-2.2%) → shearing the front side twice*the reverse side once*(18-22m / min)*steaming process No. 5*reverse side onto the machine*(18-22)m / min) → steaming TMT*tension (4-6) to obtain the all-wool single warp and single weft Serofield fabric.

[0023] Differential pretreatment of the core yarn and the covered yarn during the spinning stage enables the high-count core yarn to form a dense functional base, while the outer covered yarn retains more active groups of finishing agents. The low draw ratio of the serofel spinning process, combined with specific twist control, allows the dual-ion modified graphene to be oriented and distributed in the yarn interface layer. This, along with the flexible chains of polyether silicone oil, forms a flexible yet rigid covering network, reducing hair loss while maintaining the internal fluffiness of the yarn. In the finishing process, the combination of gradient temperature and mechanical action promotes deep cross-linking between the finishing agent components and the fibers. Moderate sizing allows the nanocellulose and modified graphene to anchor in the fiber gaps, improving abrasion resistance. Alternating overfeeding and tension control maintain the three-dimensional breathable structure of the fabric by adjusting the fiber rebound amplitude. The directional brushing and shearing processes in the special finishing process further optimize the surface hair adhesion. Ultimately, the anti-pilling properties, evenness, and fluffy soft touch are balanced through the synergy of multiple processes.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Yarn spun using the Selofir technology reduces yarn hairiness, resulting in more even yarn. Nanocellulose forms a dense protective layer on the surface of wool fibers, which, combined with the layered structure of graphene oxide, fills fiber gaps and enhances interfacial bonding, improving the bonding strength between the core yarn and the cover yarn. This helps reduce yarn hairiness and improves abrasion resistance. Bifunctional polyether silicone oil crosslinks with the fibers through its reactive groups. While maintaining the natural fluffiness of wool, its polyether segments enhance hydrophilicity, maintaining the fabric's breathability, while the siloxane skeleton gives the fabric a lasting smooth feel. Crosslinking agents promote the formation of a stable three-dimensional network among the components, and together with repair agents, they fill micro-damage to the fibers, resulting in more even yarn and improved pilling resistance. Buffers maintain a stable treatment environment, ensuring that functional substances act evenly on the fibers. This multi-mechanism synergy allows the fabric to maintain the inherent advantages of wool while achieving performance improvements. The fabric has excellent anti-pilling, abrasion resistance, and breathability, while also having a soft and comfortable feel.

[0025] 2. By grafting quaternary ammonium salt molecules onto the surface of nanocellulose, stronger affinity and dispersion stability are achieved at the fiber interface. The cationic groups on the modified nanocellulose surface form electrostatic attraction with the negatively charged regions on the wool fiber surface, promoting its directional adsorption and uniform spreading on the yarn surface. This dense and orderly coating layer effectively fills the micro-cracks on the fiber surface, reducing the tendency of fuzz to detach during processing. At the same time, the modified nanocellulose is more easily and uniformly dispersed in the aqueous treatment system, avoiding the aggregation of unmodified particles, allowing it to penetrate more completely into the interlacing points inside the yarn. Through physical reinforcement, it enhances the cohesion between fibers, thereby improving yarn evenness and inhibiting fiber slippage during friction, synergistically improving anti-pilling and abrasion resistance. The surface modification does not change the porous structure of the nanocellulose itself. The micro-channels formed by its directional arrangement, together with the natural scale layer of wool, maintain the moisture permeability and breathability of the fabric. The uniformly distributed nanoparticle layer reduces fiber friction resistance while synergistically maintaining the inherent elastic space of wool, giving the fabric a soft and fluffy feel.

[0026] 3. Aminosilanes form covalent bonds with the surface of dual-ion modified graphene. While maintaining the three-dimensional arch bridge effect formed by metal ion modification, the steric hindrance of long-chain alkyl groups reduces the stacking density of the sheets, making the graphene more uniformly dispersed in the fiber gaps. The grafted amino groups also enhance the reactivity with the polyether silicone oil in the finishing agent, forming a sheet composite encapsulated by a continuous organosilicon phase. This composite reduces fiber friction damage by buffering external force impacts through flexible chain segments, while the dispersed sheet network forms multi-level anchoring points at the root of the fibers to enhance the adhesion effect, synergistically improving anti-pilling and evenness. At the same time, the micro-cell structure formed by the grafted chains maintains the fabric's air permeability channels, and the elastic matching between the organosilicon phase and the wool scales maintains the fabric's fluffy feel.

[0059] Performance testing (1) The standards “FZ / T 01086-2020 Textile Yarn Hairiness Test Method Projection Count Method” and “GB / T 3292-1997 Textile Yarn Evenness Test Method Capacitance Method” were selected to test the hairiness index H value (3mm threshold, roots / 10m) and evenness coefficient of the yarn. The results are recorded in Table 1.

[0060] Table 1. Test results of fabric hairiness index and evenness coefficient. (2) Select GB / T 4802.2-2008 Textiles - Determination of Pilling and Friction Properties - Part 2: Modified Martindale Method as the standard. Cut 5 circular samples with a diameter of 140 mm, with the front side facing out. Use a Martindale abrasion tester with a load of 415 g to test the anti-pilling properties of the samples. Rating them in the rating box and record the results in Table 2.

[0061] (3) Select GB / T 21196.3-2007 Textiles Martindale Method for Determination of Abrasion Resistance of Fabrics as the standard, cut a sample with a diameter of 140 mm, put a standard felt pad on the back, load 9 kPa, use 600-mesh sandpaper as abrasive, rub until the sample is damaged, record the number of abrasion resistances, and record the results in Table 2.

[0062] (4) Select GB / T 5453-1997 Determination of air permeability of textile fabrics as the standard, cut 5 samples of 20cm×20cm without creases, record the air volume (mm / s) passing through a unit area per unit time, test each sample three times, take the average value after measurement, and record the results in Table 2.

[0063] Table 2. Test results of the fabric's anti-pilling, abrasion resistance, and breathability. As shown in Tables 1 and 2, the hairiness index H value of Examples 1-3 is less than 3 hairs / 10m, the coefficient of variation CV is less than 12.4%, the anti-pilling performance is greater than level 4, the abrasion resistance is greater than 21,500 revolutions, and the air permeability is greater than 242mm / s. This shows that the yarn prepared in this application can reduce hairiness, make the yarn more even, and the fabric has good anti-pilling, anti-friction and air permeability.

[0064] As shown in Table 2, the only difference between Examples 4 and 5 and Example 3 is that the synthesis ratio of the bifunctional polyether silicone oil was disrupted in Examples 4 and 5, which affected the balance between anti-pilling performance, abrasion resistance and breathability, resulting in a decrease in the performance of the fabric.

[0065] As shown in Table 2, the only difference between Examples 6-10 and Example 3 is that: in Examples 6-8, the nanocellulose was modified according to the specified ratio, and the quaternization modification treatment in Examples 6-8 enhanced the cohesion between fibers and improved the performance of the fabric; in Examples 9 and 10, the specified ratio was disrupted, and the performance improvement effect was reduced.

[0066] As shown in Table 2, the only difference between Examples 11-16 and Example 3 is that: in Example 11, zinc chloride and ferric chloride were used to modify graphene oxide, and zinc ions and ferric ions worked together to conduct electricity and fight bacteria, thus improving anti-pilling performance; in Examples 12-14, the dual-ion modified graphene was further modified according to the specified ratio, and the binding force of graphene was enhanced by aminosilane, thereby further improving wear resistance; in Examples 15 and 16, the optimal ratio was disrupted, and the performance improvement effect was reduced.

[0067] As shown in Table 2, the only difference between Comparative Example 1 and Example 3 is that the bifunctional polyether silicone oil in Comparative Example 1 was replaced with polyether amino silicone oil. Compared with Example 3, the performance of Comparative Example 1 was significantly reduced. This is because the lack of epoxy groups greatly reduced the crosslinking effect, and the wear resistance and anti-pilling properties were significantly reduced.

Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application. The technical scope of this application is not limited to the contents of the specification but must be determined according to the scope of the claims.
