Description
Technical Field
The invention relates to a production process of hollow fabrics, in particular to a one-step production process of hollow fabrics.
Background
The hollow fabric is a flower-type fabric, and partial warp yarns and weft yarns are periodically lost in the fabric forming process to cause hollowing of the fabric surface, so that a flower-type structure is formed. The hollow fabric is different from the existing common fabric in unique appearance and unique air permeability. At present, the parts needing to be lost in the production process of the hollow fabric are woven by yarns composed of water-soluble fibers such as vinylon and the like, and the hollow fabric is formed after the finished product is washed by hot water and the yarns are dissolved. The method has the biggest problems of high production cost, need of producing two kinds of yarns, difficulty in natural degradation of vinylon after the vinylon is dissolved in water, and belongs to a product with limited use in the field of textiles.

Hot water is not used, energy consumption in the production process can be reduced, and the purpose of energy conservation is achieved.
Detailed Description
The present invention is further illustrated by the following specific examples.
Example one
The one-step production process of the hollow fabric comprises an empty reed process, an empty weft insertion process, a weft density variation process and a let-off compensation process. The average warp density of the openwork fabric produced in this example was 74 threads per inch and the average weft density was 52 threads per inch.
Drafting and reeding are carried out in a warp preparation process before weaving of the conventional fabric, so that the warp threads are threaded into heddles and reeds according to the requirements of the process design. The reeding, i.e. the drawing-in process, is the last process in the warp preparation project. The warp threading task is to make the warp on the beam pass through the drop wire, harness wire and reed according to the requirement of the fabric, so as to form shed when weaving, and introduce the weft to weave the required fabric, thus the warp can be stopped in time when broken end, and the weaving defect can not be caused.
After the preparation before weaving is finished, the machine can be operated. The whole weaving process after the weaving machine is arranged comprises opening motion, weft insertion motion, beating-up motion, reeling motion and warp let-off motion. The shedding motion is the motion of a shed through which weft yarns can pass by dividing warp yarns into an upper piece and a lower piece according to the law of interweaving the warp yarns and the weft yarns. The weft insertion movement is a movement for introducing a weft thread into the shed. The beating-up motion is a motion of pushing a weft yarn introduced into the shed toward the fell. The winding motion is to draw the fabric away from the fabric forming area and wind it onto a cloth roller. The let-off motion is a motion in which warp threads are let off from a beam. The empty weft insertion referred to in this embodiment is to complete the entire weaving process without introducing weft yarns during the steps of the weft insertion movement, while the other movements are performed as usual. The let-off compensation amount is a difference between the let-off amount of the warp yarn released from the beam at each time and the let-off amount according to the normal process, and the let-off amount is decreased if the difference is a negative value, and the let-off amount is increased if the difference is a positive value.
The empty reed process is that a periodic empty reed mode is adopted when the warp yarns are reeded; an empty reed means that no warp yarn penetrates between two dents. The mode of penetrating 5 reeds and 3 reeds adopted in this embodiment. The weave used for the fabric according to the present example was a plain weave. The number of reeds per reed was 2, and the english reed number used was No. 68. The fineness of the warp and weft used was 19tex cotton yarn.
The weft insertion and miss-weaving process means that the shuttle loom does not introduce weft yarns when performing weft insertion. In the embodiment, the weft insertion process means that after 8 times of weft insertion, the weft insertion is performed, and then the weft insertion is performed for 2 to 4 times, and the process is circulated in sequence.
The weft density variation process refers to a process in which the density of weft yarns is varied according to the needs of the process during the weaving of the woven fabric. The weft density variation process means that the weft density is 300 pieces/inch during normal weft insertion, and the weft density is kept unchanged during normal weft insertion; the weft density at the time of weft insertion and weft insertion was 26 pieces/inch, and the weft density at the time of weft insertion and weft insertion was kept constant. In the embodiment, the first weft to the eighth weft are normal weft insertion in each cycle, weaving is carried out according to the weft density of 300 pieces/inch, the ninth weft and the tenth weft are empty wefts, and the weft density is adjusted to 26 pieces/inch.
The let-off compensation process refers to that the shuttle loom carries out normal let-off according to the process setting after each beating-up or increases or decreases a compensation let-off quantity on the basis of the normal let-off quantity; the compensation let-off is set by the tatting process. The let-off compensation is used for adjusting weft yarn slippage caused by weft density change, so that the fabric is smooth, and the hollow part is clearer. The problem of because the reed department elasticity that the reed brought is difficult to control, cause the fretwork size not different with the design to cause cloth cover quality is not high is overcome.
After the first weft insertion in this embodiment, the let-off compensation amount of the let-off mechanism is 1.99mm, i.e., the let-off is 1.99mm more than the normal let-off amount. After the second weft insertion, the let-off compensation amount of the let-off mechanism is 1.99mm, namely, the let-off is increased by 1.99mm on the basis of the normal let-off amount. And (4) carrying out normal let-off after the third weft is inserted, namely, adopting the set let-off quantity of the process. The let-off compensation amount after the fourth weft insertion is-1 mm, namely the let-off amount of the let-off mechanism is less than 1mm on the basis of normal let-off. After the fifth weft insertion, the let-off compensation amount is-0.5 mm. And after the sixth weft and the eighth weft are inserted, normal warp let-off is adopted. And the ninth weft and the tenth weft are empty wefts, and normal let-off amount is adopted after the ninth weft, so that let-off compensation is not performed. The let-off compensation amount after the tenth weft insertion is-1 mm.
According to the process, after the weft yarns are woven in a sliding mode, the formed fabric style meets the requirements, and the hollowing is clear.
