Description
Technical Field
The invention relates to application of weaving waste edges, in particular to a connecting method of weaving waste edges.
Background
The continuous progress of high speed, high efficiency and automation technology of the shuttleless loom replaces the traditional shuttle loom, but except a few wool fabrics and silk fabrics, the cloth edges of most looms are woven by adopting a twisted edge tissue or a tissue consistent with a basic tissue, and then the cloth edge part is removed by adopting a cutting or fusing mode, so that the neatness and the attractiveness of the cloth body part are ensured. Most of the cut cloth edges are loosened again, and relatively coarse regenerated cotton yarns are produced by an air spinning machine and are used for producing low-grade products such as mop cloth, wrapping cloth and the like, and the utilization mode is not the most efficient and reasonable. The regenerated cotton industry is clustered in the south of Zhejiang, a lot of flying dust is generated in the opening process, and part of rivers and lands are seriously polluted due to serious environmental pollution.
The amount of waste selvage generated in the weaving industry every year is large, the amount of waste selvage in one year is about 650 tons according to the estimation of a medium-sized weaving factory, and the total amount of the waste selvage is very large for a large number of weaving enterprises in the country, so that the utilization value can be greatly improved if the waste selvage can be reasonably utilized, and the pollution to the environment is reduced. For example, the method can be used for yarn reconstruction, fabric reconstruction, weaving of various household and pet cushions, and the like.
Because the structures of weaving waste edges are rich, some weft yarns with a certain length are clamped on the basis of hank yarns, and some weft yarns with a certain length are clamped on the basis of plain weave fabric segments, the whole body is in a hairbrush shape, is somewhat similar to the track yarns in fancy yarns, but has no stable yarn structure. How to fully exert the advantages of the villiform structure is a development direction for weaving waste edges reasonably. In addition, the waste selvage yarns can be innovatively applied to the reconstruction of the fabric, particularly, the novel garment fabric is developed by sewing a certain fabric segment type waste selvage structure between warp yarns and weft yarns in waste selvage and other fabrics in a certain pattern track manner, so that the style of the fabric can be enriched, the heat retention property and the fashionability are increased, and a brand new effect can be achieved.
The efficient and reasonable utilization method of the weaving slitter edge fully exerts the consolidation state between the warp and weft yarns of the weaving slitter edge, does not adopt a method of spinning after opening the selvedge fiber into single fiber again, and directly utilizes the selvedge as a raw material to develop novel yarn or fabric.
The weft yarns of the waste edges are the same as the weft yarns of the main body fabric, products produced by different enterprises are different, raw materials formed by the waste edges are very rich, most of the warp yarns of the waste edges are thicker than the warp yarns of the main body fabric, the number of the warp yarns of the waste edges is about 5, the square meter weight of the fabric of the interweaving part of the waste edges is larger than that of the main body fabric, the width of the waste edges is about 2-5 cm, certain stability exists between the warp yarns and the weft yarns of the interweaving part, but the waste edges are sold as waste products before and are not paid attention, the winding and collecting modes are random, the waste edges are broken sometimes, the situation of breaking and breaking can often occur, the waste edges are stacked in a mess in a collecting barrel, and the situation of breaking and breaking of the waste edges can occur in the collecting and transferring processes. In order to change the situation, the water-soluble vinylon sewing thread is adopted between the waste edges to sew the weaving waste edges of different sections, so that the effect similar to a yarn joint is achieved, the joint is smooth, the conditions such as bulges and the like are avoided, the weaving waste edges can be ensured to have better continuity, and the uniformity and the utilization value of the weaving waste edges are greatly improved.
Accordingly, there is a need for improvements in the art.

Detailed Description
The invention will be further described with reference to specific examples, but the scope of the invention is not limited thereto.
Example 1, joining method of woven slitter edges:
1) the connection mode of the weaving waste edge is as follows: the method is characterized in that the head end of one weaving slitter edge is lapped with the tail end of the other weaving slitter edge in the warp direction (namely, two weaving slitter edges are parallel to each other, and partial warps of the two weaving slitter edges are overlapped in the vertical direction), all the weaving slitter edges are lapped with each other in a straight line, and the length direction of the lapped weaving slitter edges is the weft direction of the weaving slitter edges. Then, the lap joint is sewn and reinforced by using a water-soluble vinylon sewing line, the sewing direction is the direction of weft yarns of the weaving waste edges (the length direction of the weaving waste edges after lap joint), so that the lap joint part of the two weaving waste edges is relatively flat without obvious bulges.
2) And sewing the overlapped weaving waste edges from one end to the other end in the length direction by using a continuous water-soluble vinylon sewing thread. The width of the weaving waste edge is 2-5 cm, and the weaving waste edge also has a certain thickness. The water-soluble vinylon sewing thread can be dissolved in the aqueous solution, the water-soluble vinylon sewing thread can be selected from various water-soluble water temperatures, such as 20 ℃, 30 ℃, 40 ℃, 60 ℃ and 80 ℃, the thickness of the water-soluble vinylon sewing thread can be selected according to the width and the thickness of weaving waste edges, the specifications of 20S/2, 30S/2 and 40S/2 (generally 30S/2) are provided, and the water-soluble vinylon sewing thread with thicker yarn is selected if the thickness of the weaving waste edges is thicker.
The weaving slitter edge is overlapped and reinforced mutually to form a straight strip shape, so that the continuous winding of the weaving slitter edge can be ensured, the weaving slitter edge is not disorderly processed in a weaving slitter edge collecting box, the weaving slitter edge which is tidy and wound is provided for further reasonable utilization, and the batch production and the subsequent product development are possible. In the situation that weaving waste edges are randomly cut short, the rough processing mode of a weaving workshop is changed, broken ends of the waste edges are reduced as much as possible, even if the broken ends are inevitable, the waste edges are also expected to be lapped flatly, tools similar to a stapler are preferably used for connecting the broken ends of the weaving waste edges, and the needle of the stapler is metal and rigid and is not easy to remove, so that the proposal that water-soluble vinylon sewing threads are adopted to replace the needle of the stapler is a good proposal. In order to ensure the unobtrusiveness of the lap joint between the weaving waste edges and reasonably control the lap joint overlapping length, the design of the vinylon yarn sewing mode and the convenience degree of sewing are also very important. In order to improve the convenience of sewing, the vinylon monofilament can be adopted, the thickness of the monofilament can be between 40D and 80D, and the vinylon monofilament used is also a vinylon monofilament dissolved in water.
The dissolving temperature of the water-soluble vinylon sewing thread is generally designed to be (40 +/-5) DEG C, so that the water-soluble vinylon sewing thread can keep better stability under the normal processing condition. The lapping length of two adjacent weaving slitter edges is 0.5 cm, so that stable sewing fastness can be ensured after sewing, and the adjacent weaving slitter edges are not torn. The optimal sewing track can be in-line 1-time sewing or in-line 2-time reciprocating sewing. All weaving slitter edges can be in a straight line overlap joint back, use continuous water-soluble vinylon sewing thread weaving slitter edges to sew along the ascending one end of length direction from the overlap joint back to the other end, compare like this and only sew the overlap joint part, holistic fastness is more excellent.
The invention uses the water-soluble vinylon sewing thread in sewing, so that the waste selvages of the broken ends are mutually sewn in time in a weaving workshop, and the continuous windability of the waste selvages is improved.
In order to facilitate processing, the portable sewing machine is fixed on a loom frame close to a weaving slitter edge collecting box, a hook of the water-soluble vinylon sewing thread is additionally arranged on the loom frame, the hook is used for placing a bobbin of the water-soluble vinylon sewing thread required for sewing and weaving slitter edges for a long time (such as one month), the size and the angle of the hook of the bobbin are designed to be suitable for the unwinding and tension control of the sewing thread, and the bobbin is suitable for the pineapple type in order to improve the uniformity of the unwinding tension. The sewing thread is not required to be provided in a mode of winding the small sewing thread core every time, and procedures of winding the small sewing thread core, installing the thread core and the like are omitted.
3) The invention can be used as a raw material for developing novel fabrics after the weaving waste edges are connected into continuous waste edges. The method is mainly used for reconstructing the shell fabric or processing the shell fabric into fancy yarns and the like, and the weaving slitter edges are used in a green and innovative way.
If the common single jersey fabric is used as the base fabric to compound the weaving slitter edges, the weaving slitter edges and the base fabric can be compounded in a sewing mode of a quilting machine or a laser compound machine, and the like, and novel fabrics can be innovatively developed. Because the water-soluble vinylon sewing thread is adopted, the rigidity of the water-soluble vinylon sewing thread is higher, and the method for removing the water-soluble vinylon sewing thread in subsequent processing is to dissolve the water-soluble vinylon sewing thread in an aqueous solution. Once the waste edge is fixed on the base cloth as the yarn or the decorative material, the base cloth with the waste edge is put into water, and the water-soluble vinylon sewing thread is dissolved in the water, thereby being beneficial to the utilization of weaving the waste edge. The removal method is also very simple, and the water-soluble vinylon is dissolved into the aqueous solution only by putting the polyvinyl alcohol into water at the corresponding temperature. This ensures that the smoothness of the joint in waste edge applications is maintained, even if the presence of the joint is not visible. The removal process can be completed in combination with the after-finishing of the fabric or garment, and a separate process is not required.
The weaving slitter edge can be processed into a form similar to fancy yarn in a mode of uniformly cutting in the longitudinal direction (warp direction), the fancy yarn can be directly used as fancy yarn, the fancy yarn can be processed on a flat knitting machine sweater at intervals, and can also be used as weft yarn to be processed into fancy fabrics, and unexpected effects can be obtained.
The overlapping sewing requirement between the weaving waste edges is not high, the overlapping sewing requirement is only needed as long as the separation in the length direction is not generated, the strict sewing requirement like common sewing is not needed, the overlapping sewing between the weaving waste edges is only temporary connection between the weaving waste edges, and once the weaving waste edges are processed into corresponding finished products, the water-soluble vinylon sewing thread is expected to be simply separated. In order to prevent the water-soluble vinylon sewing thread from being separated, the water-soluble vinylon sewing thread with the length of 1-2 cm reserved at the sewing head is reasonable.
Experiment 1:
the width of the waste edge of the artifacts is 3 cm, the thickness is 0.8 cm, the water-soluble temperature of the water-soluble vinylon sewing thread is 40 ℃, and the fineness specification of the water-soluble vinylon sewing thread is 20S/2. The lapping length between the weaving slitter edges is selected to be 0.5 cm, and the weaving slitter edges are reinforced by adopting a straight one-way sewing mode.
Experiment 2:
the width of the weaving waste edge is 2 cm, the thickness is 0.5 cm, the water-soluble temperature of the water-soluble vinylon sewing thread is selected to be 40 ℃, and the fineness specification of the water-soluble vinylon sewing thread is selected to be 30S/2. The lapping length between the weaving slitter edges is selected to be 0.5 cm, and the weaving slitter edges are reinforced by adopting a sewing mode of reciprocating for 2 times.
Experiment 3
The width of the waste selvage of the weaving waste selvage is 1 cm, the thickness is 0.4 cm, the water-soluble temperature of the water-soluble vinylon sewing thread is selected to be 40 ℃, and the fineness specification of the water-soluble vinylon sewing thread is selected to be 40S/2. The lapping length between the weaving slitter edges is selected to be 0.5 cm, and the weaving slitter edges are reinforced by a sewing mode of reciprocating for 2 times.
Compared with the prior art, the invention has the technical advantages of convenience and environmental protection, the weaving slitter edge use value can be realized only by properly modifying the existing equipment and raw materials, the portable sewing machine is skillfully combined with the weaving slitter edge collecting barrel of the weaving machine, the water-soluble vinylon is used for connecting the sewing threads of the weaving slitter edges, and the vinylon threads are dissolved and removed after the weaving slitter edges are processed into final finished products, so that the investment is not increased too much, but the use value of the weaving slitter edges and the possibility of redevelopment can be greatly improved.
Finally, it is also noted that the above-mentioned lists merely illustrate a few specific embodiments of the invention. It is obvious that the invention is not limited to the above embodiments, but that many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the invention.
