Description

Down-proof fabric and production method thereof

Technical Field

The invention relates to the technical field of spinning, in particular to a down penetration preventing fabric and a production method thereof.

Background

The specifications of the down penetration preventing products sold in the market mainly comprise the following specifications: 1.40S 40S 133X 100, 2.60S 60S 140X 140, 3.80S 80S 173X 156, 4.100S 100S 200X 170, the characteristics are that the higher the count of yarn, the better the effect of preventing the penetration and the velvet and the larger the weaving difficulty. The down penetration resistance is the performance of the fabric for preventing down or feather from penetrating and leaking from gaps among yarns, and the size of the gaps among the yarns in the fabric is expressed by a coverage coefficient. According to the introduction of the third edition of cotton weaving handbook of Chinese textile Press, the maximum coverage coefficient of the warp and weft theories of the balanced weave plain weave fabric is 16.1, and theoretically, no anti-drilling down fabric with the coverage coefficient exceeding 16.1 exists.

The weaving density of the fabric is mainly influenced by two factors of yarn diameter and fabric texture. The thicker the yarn diameter, the lower the buckling behavior of the fibers during beating up, and the larger the yarn gap in the fabric. The plain weave fabric has compact structure and small migration gaps among yarns, and is taken as the first choice for weaving the penetration-resistant pile fabric.

The difficulty in developing the extra-high count high density fabric lies in the broken ends of warp yarns, the extra-high count high density fabric is made into the feather-proof fabric, the difficulty is increased in that the cloth cover is vibrated and then the cloth fell tension returns, and normal weaving is difficult to complete.

The yarn channel, the yarn guide hole, the yarn guide ceramic nozzle and each roller of the head are required to have no damage and burr so as to prevent the yarn from generating regenerated hairiness and hanging up in the warping passage.

The upper and lower positions of the bobbin support are required to be aligned straightly; the beam disk is polished by sand paper to ensure no burr.

All channels and machine heads of the yarns are required to be thoroughly cleaned before driving, and cleaning is timely carried out in the driving process to ensure that no accumulated flowers exist at each part and prevent flying flowers from attaching; accumulated patterns of the expansion reed are cleaned at any time, and accumulated patterns are below the yarn surface in the expansion reed.

And the automobile is made to go round in time during the driving process, and whether the rotation of each tension disc is flexible or not and whether the tension disc falls off or not is observed.

The two sides of the car are aligned strictly at 5 meters before starting, and no dilute or folding condition appears, so that tension arrangement, winding and uniformity are achieved, and the generation of flying and regenerated hairiness is reduced.

In operation, the yarn ends are required to be evenly gathered, accurately found, smoothly arranged and firmly connected so as to eliminate twisted yarn ends and broken yarn ends and improve the quality of warp beams.
