Ribbon is a widely used textile products, shoes, clothing, industry, agriculture, military supplies and many other industries are in great demand for ribbon. The quality of ribbon production has a direct impact on the use of the ribbon. However, due to the multiple production steps of the ribbon, it is inevitable that some ribbon manufacturers will have some small problems in the production process, which will directly affect the quality of the final ribbon produced. Timely finding the causes of these problems can help enterprises avoid more losses. Below, follow hebei guanglian to have a look at some common problems in ribbon production, and understand the causes and preventive measures.
One,
Causes: 1. Uneven penetration of steel buckle. 2. Uneven yarn pulling at the end of the pan. 3. Wrong position of steel buckle. 4. Wrong connection method.
Preventive measures: 1, the steel buckle puncture method must follow the normal puncture method, 1 or 2 groups of puncture method. 2, the larger side of the loose, pull some, until the other side as flat or less than 1-5 turns. 3, steel buckle and generally knitting needle distance, there is a steel buckle empty distance. 4, according to the need of shoe material ribbon, cent goes up lower layer is received, or it is cent, left and right sides is received, want to divide commonly fluctuation, if have two kinds of above methods or grain on a belt, be about to separate receive.
Two, wave
Causes: 1. Uneven yarn wearing of steel buckle, too much yarn on both sides and too little in the middle. 2. The steel buckle is too large and the weft yarn is too tight. 3, the end of the drawstring uneven, both sides of the tension, the middle pull too loose. 4, the wrong way to connect the yarn, balance pressure is not good.
Preventive measures: 1. Standard steel buckles shall be selected and punctured in one or two groups. 2, according to the width of the ribbon, and then choose the steel buckle to wear. 3, the middle and both sides of the yarn for a few, or the middle of the relatively loose pull down some. 4, according to the webbing method needs to be connected, the balance of the number of pendant press the average.
Three, needle edge bad
Causes: 1. Uneven weft thickness. 2, knitting needle on the wrong way, too long or too short. 3, pan head walk is not normal, sometimes tight, sometimes loose. 4. The weft wheel is not round enough and deformed. 5, the needle fixed porch wear.
Preventive measures: 1. Change another filling. Generally speaking, the length of the knitting needle is just enough to return the weft yarn. 3. Fix both sides of the pan head firmly, do not let the pan head rest on the iron frames on both sides. 4. New weft wheel has been replaced. 5. Replace the fixed rod or machining.
Four, fuzz
Cause of formation: 1, needle edge fluff. 2, cloth edge fuzz. 3, the surface of the ribbon.
Preventive measures: 1. The needle plate of some garment knitting factories has been damaged due to long time use. New needle plate; The knitting needle has been damaged and replaced with a new one; Pressure belt plate is too tight, relax pressure belt plate; If the filling is not finished, adjust the distance between the weft needle and the knitting needle so that the filling can be finished. 2, the weft hook steel buckle, the weft into the weft pole; If the steel buckle is damaged, replace it with another one; The raw material itself has hair, if it is partially fluffed, replace the fluffed material, if it is too much fluffed, do the whole inspection belt after finishing the goods. 3, weft needle damage, change a, or with gauze dozen; Steel buckle damage, with gauze dozen, or another steel buckle; The palm piece is damaged or the stop piece is damaged and replaced with a new one.
Five, the size
Reasons for the formation: 1, the raw material thickness is uneven, so that the ribbon has a small. 2, steel buckle wear too big or too little, so that the ribbon size. 3. The weft wheel becomes loose during operation. 4, the weft through the rod spring, which go yarn wool.
Preventive measures: 1, to often measure the width of the shoe material cloth ribbon, immediately transferred when found unqualified. 2, wear steel buckle wear not too big or too small, wear unqualified re-wear, not forced production. 3. Tighten and fix the filling wheel. 4, often loosen the outside of the spring, so that there is yarn inside the wool can come out.
