Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by those skilled in the art without making any inventive effort based on the embodiments of the present invention are within the scope of protection of the present invention.
The multi-layer hollow fabric is a three-dimensional hollow fabric having two hollow core layers, which includes upper, middle and lower three face layers and upper and lower two hollow core layers, and although the multi-layer hollow fabric is only one more hollow core layer than the a-layer hollow fabric from the structural point of view, the conventional weaving method of the a-layer hollow fabric has not been applied to the weaving of the multi-layer hollow fabric at all, and since the multi-layer hollow fabric involves two hollow core layers and three face layers, the weaving process thereof is more complicated than that of the a-layer hollow fabric, and more factors need to be considered in the weaving process. In the prior art, in order to obtain the hollow fabric with the multi-interlayer structure, two layers of hollow fabrics with the interlayer A are generally formed after being integrally compounded, so that the integral forming of the hollow fabric with the multi-interlayer cannot be realized, and the method can realize the hollow fabric with the multi-interlayer structure, but the hollow fabric is not an integral body, and an interlayer interface exists, so that the integral stability and the expandability are insufficient.
Accordingly, based on the above-mentioned problems, in order to achieve the integral weaving continuous molding of the multi-layer hollow fabric, the present invention provides a weaving method of the multi-layer hollow fabric, which is woven by using a double rapier loom through lifting and beating-up; the weaving comprises the steps of forming an upper layer by upper warp yarns and upper weft yarns, forming a lower layer by lower warp yarns and lower weft yarns, forming an upper middle layer by upper middle layer warp yarns and upper middle layer weft yarns, forming a lower middle layer by lower middle layer ground warp yarns and lower middle layer weft yarns, and connecting and solidifying the upper layer, the upper middle layer, the lower middle layer and the lower layer together by first velvet warp yarns, second velvet warp yarns, third velvet warp yarns and fourth velvet warp yarns respectively to form the multi-interlayer hollow fabric.
In the embodiment of the invention, as shown in fig. 1 and 2, firstly, warp yarns and weft yarns are interwoven to form an upper layer, an upper middle surface layer, a lower middle surface layer and a lower layer respectively, and then the upper layer, the upper middle surface layer, the lower middle surface layer and the lower layer are connected and fixedly connected together through first velvet warp yarns, second velvet warp yarns, third velvet warp yarns and fourth velvet warp yarns, so that continuous integral forming of the multi-interlayer hollow fabric is realized.
According to some preferred embodiments, as shown in fig. 2, the first pile warp yarn, the second pile warp yarn, the third pile warp yarn and the fourth pile warp yarn are respectively connected and consolidated as follows:
after M-type consolidation is carried out on the first velvet warp yarn and the upper layer weft yarn, WN-type consolidation is carried out on the first velvet warp yarn and the upper middle layer weft yarn and the lower middle layer weft yarn, W-type consolidation is carried out on the first velvet warp yarn and the lower layer weft yarn, and MU-type consolidation is carried out on the first velvet warp yarn and the upper middle layer weft yarn and the lower middle layer weft yarn;
after W-shaped consolidation is carried out on the second velvet warp yarn and the lower layer weft yarn, MU-shaped consolidation is carried out on the second velvet warp yarn and the upper middle layer weft yarn and the lower middle layer weft yarn upwards, M-shaped consolidation is carried out on the second velvet warp yarn and the upper layer weft yarn upwards, and WN-shaped consolidation is carried out on the second velvet warp yarn and the upper middle layer weft yarn and the lower middle layer weft yarn downwards;
after M-type consolidation is carried out on the third velvet warp yarn, the upper middle layer weft yarn and the lower middle layer weft yarn, W-type consolidation is carried out on the third velvet warp yarn, the lower middle layer weft yarn and the lower middle layer weft yarn, MU-type consolidation is carried out on the third velvet warp yarn, the upper middle layer weft yarn and the lower middle layer weft yarn, M-type consolidation is carried out on the third velvet warp yarn, the upper middle layer weft yarn and the upper middle layer weft yarn, and U-type consolidation is carried out on the third velvet warp yarn, the upper middle layer weft yarn and the lower middle layer weft yarn;
the fourth pile warp yarn is subjected to W-type consolidation with the upper middle layer weft yarn and the lower middle layer weft yarn, then is subjected to M-type consolidation with the upper layer weft yarn, is subjected to WN-type consolidation with the upper middle layer weft yarn and the lower middle layer weft yarn, is subjected to W-type consolidation with the lower layer weft yarn, and is then subjected to N-type consolidation with the upper middle layer weft yarn and the lower middle layer weft yarn;
And continuously circulating according to the consolidation mode so as to fixedly connect the upper surface layer, the upper middle layer, the lower middle layer and the lower layer together.
For the weaving process of the multi-layer hollow fabric, the trend of the pile warps among all the surface layers is the key of successful weaving of the multi-layer hollow fabric, and is limited by only 1 pile warp pan head and 4-page pile warp heald frames, so that the principle that the whole pile warp structure of the fabric is symmetrical is always maintained for ensuring that the whole weaving process is clear and the fabric structure is stable, and the effective control of the pile warps on the middle surface layer is realized. In the embodiment of the invention, the upper layer, the upper middle surface layer, the lower middle surface layer and the lower layer are fixedly connected together by adopting four velvet warps, and the four velvet warps are respectively designed in a fixedly connecting mode with weft yarns in the upper layer, the upper middle surface layer, the lower middle surface layer and the lower layer, so that the symmetrical coordination of two core layer structures is ensured, the cavity structures of the two core layers are continuous and clear, and the good stability of the whole hollow fabric after being formed is ensured. In this embodiment, as shown in fig. 2 or fig. 3, the pile warp space structures of the upper core layer and the lower core layer are in one-to-one correspondence, and are in an 8-shaped and V-shaped alternate structure, so that the overall structure stability is strong, and the cavity structures of the two core layers are continuous and clear. The density of the upper and lower core layers is preferably 20/cm, i.e. 10/cm layers.
According to some preferred embodiments, the multi-layer hollow fabric has an overall weave repeat weft yarn count of 24 picks to 360 picks/repeat; in embodiments of the present invention, the overall weave repeat weft yarn count of the multi-layer hollow fabric is preferably a multiple of 4, and may be, for example, 24 picks/repeat, 28 picks/repeat, 32 picks/repeat, 36 picks/repeat, 40 picks/repeat, 44 picks/repeat, 48 picks/repeat, 80 picks/repeat, 100 picks/repeat, 200 picks/repeat, 300 picks/repeat, or 360 picks/repeat.
In fig. 1 and 2 of the present invention, the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 are numbers of heald frames in the double rapier loom, respectively, and (1) (2) (3) … … are weft insertion sequences of weft yarns, respectively.
In the weaving process of the multi-interlayer hollow fabric, the weft insertion sequence of the two rapiers directly affects the effective forming of the middle surface layer and the effective structure holding of the velvet warps during jumping and inserting among the three surface layers, so that after integral analysis and multiple tests, the upper middle surface layer and the lower middle surface layer are beaten up to form the hollow fabric structure and the stability after forming is optimal, and therefore, the weft insertion sequence of the embodiment is set according to fig. 2.
According to some preferred embodiments, the double rapier loom comprises 12 columns of heald frames; wherein, the 1 st to 4 th columns of heald frames are used for penetrating into the velvet warp yarns, the 5 th to 8 th columns of heald frames are used for penetrating into the upper middle layer ground warp yarns and the lower middle layer ground warp yarns, the 9 th to 10 th columns of heald frames are used for penetrating into the upper layer ground warp yarns, and the 11 th to 12 th columns of heald frames are used for penetrating into the lower layer ground warp yarns.
According to some preferred embodiments, in the double rapier loom, 1, 2, 3 and 4 rows of heald frames are middle heald eyes, the motion ranges of the heald frames are divided into "∈", "-", "}", 5, 6, 9 and 10 rows of heald frames are upper heald eyes, the motion ranges of the heald frames are divided into "∈" and "∈",7, 8, 11 and 12 are lower heald eyes, and the motion ranges of the heald frames are divided into "∈" and "∈".
It should be noted that, "≡", "", and "∈" in the embodiment of the present invention represent upward movement, lateral movement, and downward movement of the heald frame, respectively.
In the embodiment of the invention, a Van der Waals VTR42 type double rapier loom is adopted for weaving, the effective width of the loom is 1270mm, the loom is provided with 12 rows of heald frames, wherein, heald holes corresponding to 1-4 rows of heald frames are arranged at the whole central position, the number of heald wires of each row of heald frames is more than or equal to 635, 5, 6, 9 and 10 rows of heald frames are upper-layer heald frames, corresponding heald holes are arranged at the whole upper-layer position, 7, 8, 11 and 12 rows of heald frames are lower-layer heald frames, corresponding heald holes are arranged at the whole lower-layer position, the number of heald wires of each row of heald frames is more than or equal to 645, and the heald hole eyes in the embodiment of the invention are preferably ceramic holes so as to reduce the abrasion of yarns, thereby ensuring the reduction of yarn hairiness in the whole weaving process. In the embodiment of the invention, 1 st to 4 th columns of heald frames in the loom are used for penetrating into the pile warp yarns, 5 th to 8 th columns of heald frames are used for penetrating into the upper middle layer ground warp yarns and the lower middle layer ground warp yarns, 9 th to 10 th columns of heald frames are used for penetrating into the upper layer ground warp yarns, and 11 th to 12 th columns of heald frames are used for penetrating into the lower layer ground warp yarns.
Before weaving the hollow fabric, the structures of the surface layer, the core layer and the whole fabric of the fabric are designed respectively, so that the continuity and stability of the later weaving are ensured.
Design of a hollow fabric surface layer structure: as shown in fig. 1, the multi-interlayer hollow fabric is integrally provided with 3 surface layers, namely an upper surface layer, a middle surface layer (comprising an upper middle surface layer and a lower middle surface layer) and a lower surface layer, and the heald frames for weaving the three surface layers are 8 rows, so that the effective forming of the fabric in the weaving process is ensured, the stability of the integral hollow fabric structure is prevented from being adversely affected by the surface layers, and the principle of structural symmetry of heald frame movement is required to be adhered to in structural design of the surface layers; as shown in fig. 1, for example, the 9 th and 10 th heald frames are used for weaving the upper layer, and it is necessary to ensure that the movement directions of the 9 th and 10 th heald frames are symmetrical during the weaving of the upper layer; for example, during the weaving of the lower layer, it is necessary to ensure that the directions of movement of the 11 th and 12 th columns of heald frames are symmetrical.
Design of a hollow fabric core layer structure: as shown in fig. 2, the multi-interlayer hollow fabric has 2 core layers, namely an upper core layer and a lower core layer, and the total number of heald frames for weaving the two core layers is 4, so as to ensure the effective forming of the fabric in the weaving process and avoid the adverse effect of the two core layers on the stability of the whole hollow fabric structure, the 4-column heald frames for weaving the pile warp yarns need to be considered in addition to following the 'structural symmetry' of the heald frame movement, and the trend of each column heald frame in three surface layers and the position corresponding relation of the corresponding heald frames during reed wearing, namely, the two-column heald frame yarns with asymmetric structures cannot be worn in one reed tooth, otherwise, the weaving is not clear. As can be seen from fig. 2, in the embodiment of the present invention, the movement directions of the 1 st row heald frame and the 2 nd row heald frame are symmetrical, the movement directions of the 3 rd row heald frame and the 4 th row heald frame are symmetrical, and the pile warp yarns in the four row heald frames all participate in the weaving of the three surface layers, so that the overall structure is symmetrical and coordinated, which is favorable for the structural stability after the multi-layer hollow fabric is formed, and further the subsequent composite forming process is easy to realize.
When the design of the surface layer structure and the core layer structure is completed, two parts are integrated into a whole, and at the moment, the circulation numbers of the tissue yarns of the three surface layer structures and the two core layer structures are matched, in the embodiment of the invention, the circulation number of the surface layer structure is preferably 4 wefts/circulation, the circulation number of the core layer structure is preferably 36 wefts/circulation, and the tissue circulation number of the whole hollow fabric structure is determined to be 36 wefts/circulation after the least common multiple of the surface layer structure and the core layer structure is taken; secondly, the weft insertion sequence of the weft yarns during weaving needs to be considered, so that the weft insertion sequence of the two rapiers directly influences the final effective forming of the middle surface layer and the effective structural holding of the velvet warp yarns during jumping and inserting among the three surface layers, and therefore, through overall analysis, the weft insertion sequence of the embodiment is set as shown in table 1; thus, the fabric structure design is completed.
According to some preferred embodiments, in the weaving process, the reed adopts 60# to 150# and the weft density is 32-60 roots/cm; the drafting sequence is 1.5.6.2.9.10.3.7.8.4.11.12 for one cycle, and the reed-passing sequence is 1.5.6.2.9.10/3.7.8.4.11.12 for one cycle.
In the weaving process of the hollow fabric, the relative positions of the pile warp yarns and the ground warp yarns are determined by the drafting sequence and the reed-passing sequence, so that the yarns in the same reed dent are sticky in the motion process to cause unclear openings, and when serious, part of the pile warp or ground warp cannot be fused into the whole fabric in the weaving process to generate floating yarns to form cloth defects, so that the drafting sequence and the reed-passing sequence are very important. In the embodiment of the invention, in order to ensure the smooth proceeding of the weaving process of the hollow fabric and the better organization effect of the hollow fabric, the embodiment of the invention adopts a No. 60-150 reed, each reed of the reed penetrates into 2 wool warps and 4 ground warps, according to the fabric design structure, the drafting sequence is designed as 1.5.6.2.9.10.3.7.8.4.11.12 one cycle, and the penetrating sequence is designed as 1.5.6.2.9.10/3.7.8.4.11.12 one cycle, thus, the wool warps can separate the ground warps in the arrangement sequence, and the ground warps of two adjacent heald frames are ensured to weave the same surface layer, thus, in the movement process of the heald frames, the two adjacent heald frames only involve the weaving of one surface layer, thereby avoiding the conditions of adhesion and tearing and unclear opening caused by the movement of yarns and heald frames in other surface layers in certain positions.
Meanwhile, in order to ensure that the whole forming of the hollow fabric is symmetrical and the stress is uniform in the weaving process, and realize the good forming stability of the hollow fabric, the reed adopted in the embodiment of the invention is a special-shaped section reed, for example, a 1-23-78270 type special-shaped section reed of BURCKLE in France, and the reed can ensure that the positions of weaving openings where two weft yarns which are simultaneously input in beating up are consistent with the beating-up position of the reed, so that the good forming stability of the hollow fabric is realized.
According to the design structure of the hollow fabric, the higher weft density is beneficial to the formation of the fabric, but is not beneficial to the continuous weaving of the fabric, and the problems of fabric front-end and fabric finishing distortion and the like are easily caused, so that in order to further ensure the smooth weaving process of the hollow fabric and further ensure the good structural stability of the hollow fabric, the weft density is preferably set to be 40 yarns/cm after multiple experiments.
According to some preferred embodiments, the number of overall weave repeat weft yarns of the multi-layer hollow fabric is preferably 36 picks/repeat, and the lift beat-up weaving process is specifically as follows, taking as an example the number of overall weave repeat weft yarns is 36 picks/repeat:

to this end, the lifting and beating-up are carried out by taking thirty-six wefts as one cycle, and the next cycle is entered for weaving in turn.
It should be noted that, when the number of the overall weave circulation weft yarns of the multi-layer hollow fabric in the embodiment of the present invention is other circulation, the sequence of the lifting and beating-up needs to be adaptively adjusted.
According to some preferred embodiments, the yarn types of the pile warp, warp and weft are at least one of alkali-free glass fiber yarns, quartz fiber yarns, carbon fiber yarns, metal wires, ceramic-based fiber yarns or polyimide yarns.
It should be noted that, in the embodiment of the present invention, the yarn types of the pile warp yarn, the warp yarn and the weft yarn are mainly selected according to the use and performance requirements of the final hollow fabric, including but not limited to the above types of yarns, for example, ultra-high molecular weight polyethylene yarns and chemical fiber yarns (such as terylene, aramid, etc.).
According to some preferred embodiments, the upper layer and the lower layer are each at least one of plain, twill, or satin; wherein the density of warp and weft yarns is 8-15 (e.g., 8, 10, 12 or 15);
The upper middle layer and the lower middle layer are at least one of plain weave, twill weave or satin weave; wherein the density of warp and weft yarns is 8-15 (e.g., 8, 10, 12 or 15) yarns/cm.
In the embodiment of the invention, the upper layer, the upper middle surface layer, the lower middle surface layer and the lower surface layer can also be of other combined plane weave structures, such as a heavy plain weave, a square plain weave, a reinforced twill, a mountain-shaped twill, a reinforced satin, a modified satin and the like, but when the upper layer, the upper middle surface layer, the lower middle surface layer and the lower surface layer are all preferably of plain weave structures, compared with other structures such as twill, the plain weave structures are beneficial to ensuring the consolidation of yarns in the structures of the surface layers, and further beneficial to ensuring the stability of the whole structure of the finally formed multi-interlayer hollow fabric.
According to some preferred embodiments, the thickness of both the upper and lower layers is 0.2-2.0 mm (e.g., may be 0.3mm, 0.4mm, 0.8mm, 1.2mm, 1.8 or 2.0 mm), the height between the upper and upper intermediate layers and between the lower and lower intermediate layers is 3.0-20.0 mm (e.g., may be 3mm, 5mm, 7mm, 10mm, 15mm or 20mm, etc.), and the total multi-layer hollow fabric molding height is 4-48 mm (e.g., may be 4mm, 8mm, 10mm, 20mm, 30mm, 40mm or 48 mm).
In the embodiment of the invention, in the weaving process of an upper loom, the ground warp beam adopts an active servo driving tension control system in combination with the design structure of the double rapier equipment and the fabric and the warp and weft density requirements, the ground warp beam is dynamically balanced within the range of 4.0-4.5, the pile warp beam is the key of whether the hollow fabric can be raised, the pile warp tension control adopts a swinging rod type passive tension control system so as to ensure that the pile warp beam can still be effectively formed under the condition that the tension states of the pile warp beam are greatly different from those of interweaving, meanwhile, in order to ensure the continuous stability of the forming height of the multi-interlayer hollow fabric, the servo driving warp feeding system is adopted to accurately feed the pile warp, the warp feeding quantity is controlled to be between 1.0 and 3.0, and the winding tension is mainly formed by the difference between the rotating speed of a roller of a winding mechanism and the forming speed of the fabric weaving, so that the structure of the multi-interlayer hollow fabric in the embodiment presents a three-dimensional form, the winding tension setting cannot be too large, the fabric structure dislocation damage caused by winding is avoided, and the winding tension is preferably 10% -20% according to the parameter setting of the double rapier equipment.
As shown in fig. 3, the hollow fabric in the embodiment of the present invention is a double-interlayer hollow structure after weaving, at this time, the conventional winding and packaging form of the core barrel is unfavorable for long-term storage and subsequent composite use of the structural fabric, the conventional winding form generally compresses the three-dimensional fabric into a planar fabric for storage, and after a period of storage, the structure is difficult to directly restore to the original three-dimensional state, so that the hollow fabric in the embodiment is wound and stored in a middle transition storage mode, and the fabric is integrally unfolded and laid after being taken off from the machine for subsequent composite use.
In a second aspect, the present invention provides a multi-layer hollow fabric produced by the weaving method of any one of the first aspects.
The invention can realize the integral continuous weaving forming of the multi-interlayer hollow fabric, the whole weaving process is stable and reliable, the multi-interlayer hollow fabric has a stable structure, the heights of two hollow layers and the thicknesses of three surface layers of the fabric can be designed, and the embodiment of the invention can realize the regulation and control of the integral thickness of the multi-interlayer hollow fabric. The multi-interlayer hollow fabric prepared by the embodiment of the invention has better overall consistency, expandability and structural stability in practical application, solves the problem of continuous forming of the overall weaving of the multi-interlayer hollow fabric, and lays a foundation for future industrialized mass production.
In order to more clearly illustrate the technical scheme and advantages of the present invention, a multi-layered hollow fabric and a weaving method thereof will be described in detail by way of one embodiment.
