The warp and weft yarns of the fabric located at the temples were cut off one by one. The yarns became fluffy and could easily be pulled off.
There are many factors that cause sideburns. There are mainly the following aspects:
(1) The position of the edge box is too high or too low. The full-width weave of the fabric is not on the same horizontal line, and the two sides of the fabric are formed to protrude outward and the cloth body is concave inward. During the beat-up, the cloth body is affected by the beating force, and the production cow beats, and the cloth inside the edge baffle box cannot move due to the extension of the licker-in roll, thus resulting in relative torsion, and easily causing a large amount of edge brace.
(2) The fabric tension is too large, and the warp yarn is tightly attached to the edge-stitching roller, resulting in the edge-pulling caused by cutting the warp and weft yarns.
(3) Fabrics with wider widths or larger weft rates are more prone to buckling. When the cloth on both sides of the fabric leaves the gusset roll, it loses the support of the gusset roll, which is shrinking toward the center of the cloth body, and the spur roll puncture tip has a transverse tension against the cloth structure, resulting in cutting. Warp opportunities.
(4) Improper use of the edge-spreading roller, or the newly-purchased edge-bearing licker-in roller is not processed in time, and the blunt-tipped portion is dull, or the sharp-pointed but curved-fishing shape is formed, and the special warp yarn or weft yarn is pulled off.
(5) The inside of the edge-spreading basin is characterized by short loops, falling pulp, falling objects and other obstructions, which affect the flexibility of the rotation of the licker-in and cause the inconsistency between the speed of the licker-in and the surface of the cloth, which causes the piercing point to cut off the weft yarn and produce the side brace.
(6) The size of the joints of the side gussets, the gusset lid (L47, L50), and the gusset box seats (L46, L49) are misaligned or skewed.
The joint is too small (less than the specified (0.8mm), the angle of the fabric surrounding the licker-in increases, the position of the dip of the licker-in roll is also increased, so that the depth of penetration increases, the difficulty of depilation, and the proneness of the edge prosthesis; If the seam is too large (greater than the specified 0.8mm), the warp and weft yarns are also likely to be cut to form a side brace or camouflage.The seams are not flush, the gaps are of a size, the large end of the seams is thorns, and the small end After stabbing, the speed difference of fabric forming in the stabbing is different, and the cutting phenomenon occurs.
The internal assembly of the edge box is not up to specification. The middle ribs of the edge box cover (L47, L50) are not parallel to the front and rear rows of licker-in rollers, affecting the size of the corners of the two rows of the licker-in rollers in the lash box and the width of the envelops, resulting in two rows. Difference between speeds of thorns. It is easy to hang out or cheat.
(7) Rolling licker-in (L00-1) The bristles are too sharp on the iron sheet, and the mouth or the piercing hole are dull and dull.
(8) Weak adjustment of the temperature and humidity in the weaving workshop makes it easier to produce large-area temples, especially when weaving viscose fabrics. More sensitive and more influential.
(9) The let-off device is poor, the tension fan-shaped rod (C3) moves up and down too much, the saw-tooth gear support head (B23, B24, B25) wears off, the tension of the warp yarns is suddenly loose and loose, easy to produce regular side ç–µ.
(10) If the fabric tension is too tight, it will get a little bite when it comes to the licker-in (L55-L58).
(11) In the falling cloth operation, due to the large diameter of the wooden roller, it is easy to rub against the bristles on the roll of the cloth to produce a similar brace.
(12) On the side of the box cover, the screw head hits the front of the box cap (Q11) or crashes the anti-shuttle iron.
(13) After the flat car or dismantling the bad cloth, pull the cloth into the temple box by hand.

Women's dress style is fit for the spring and summer, so almost basic style use bright-coloured print and dye for fabric, usually fashion style needs embroidery, special print and paillette in the main parts of clothes or fabric, and some dazzling styles are even sewing diamond on neck and chest by handmade. Nomally spring and summer style in thin and breathable material which like cotton, polyester, T/C, linen etc, and autumn and winter style in thick and warn material which like cotton, polyester etc, but fabirc needs thick.
