Preventive measures for quality problems of ribbon

Editor's Note: In the process of producing ribbon, there are some problems in the ribbon manufacturer, which lead to the deviation of product quality. If there are problems in the production of ribbon, the product will be scrapped. Then, the following small knitting details how to avoid some problems in the production process, so as to improve the productivity of the ribbon.

In the process of producing ribbon, some factories will have some problems, which will lead to the insufficient quality of products. The ribbon is widely used in clothing, industry, agriculture, military supplies, transportation and other industries. So the quality of the ribbon is related to the visual effect of the product, if the production of which ring in the ribbon. If there are problems in the production process, it will lead to the scrap of products. Then how can we avoid these problems in the production process, improve the qualified rate of ribbon production and eliminate the troubles of some manufacturers? Next, we introduce some problems often encountered in the production process of ribbon, and the corresponding solutions and preventive measures:

I. Bend Belt

Causes of formation:

1. The unevenness of steel buckle 2. The unevenness of winding head 3. The misplacement of steel buckle 4. The mistake of yarn joining method

Preventive measures:

1. The steel piercing method must be in accordance with the normal piercing method, one or two groups of piercing method. 2. Pull off the larger and looser side until it is as flat as the other side or less than 1-5 laps. 3. The distance between the steel buckle and the knitting needle is generally the distance between the steel buckle and the knitting needle. 4. According to the needs of the ribbon, it should be divided into upper and lower layers, or between upper and lower layers, or between left and right layers. If there are more than two ways or lines in a ribbon, it should be connected separately.

2. Rising Waves

Causes of formation:

1. The steel yarn is not uniform. There are too many yarns on both sides and too few yarns in the middle. 2. Too large steel buckle and too tight weft tension. 3. The winding is uneven, the tension on both sides is tight, and the tension in the middle is too loose. 4. The yarn connection method is not right and the balance pressure is not good.

Preventive measures:

1. Choose standard steel buckles and wear them in groups 1 or 2. 2. Select steel buckles to wear according to the width of the ribbon. 3. Change the yarns in the middle and on both sides, or pull down the looser yarns in the middle. 4. According to the method of ribbon weaving, it needs to be connected. The balance drop is averaged according to the number of bars.

3. Poor needle edge

Causes of formation:

1. The uneven weft fineness: 2. The knitting needle is wrong, too long or too short. 3. The tray head is abnormal, sometimes tight and sometimes loose. 4. The weft wheel is not round enough and has been deformed. 5. Wear of knitting needle.

Preventive measures:

1. Change another weft. 2. Knitting needle is based on the length of the ribbon. Generally speaking, the length of the knitting needle is just enough to return the weft. 3. Fix the two sides of the plate head firmly. Do not let the plate head rest on the two sides of the iron frame. 4. Replace the new weft wheel 5, change the fixing rod, or go to the processing.

IV. Hairing

Causes of formation:

1. Needle bristling. 2. Edge fuzzing 3. Ribbon surface fuzzing

Preventive measures:

1. The needle plate has been damaged for a long time. Change the new needle board; the knitting needle has been damaged and the new knitting needle has been changed; the pressing plate is too tight to relax the pressing plate; the weft yarn is not finished, the distance between the weft knitting and the knitting needle is adjusted so that the weft yarn can be hung up.

2. Hang the steel buckle of the weft yarn and put the weft yarn into the weft-passing rod; the steel buckle is damaged and another steel buckle is replaced; if the raw material itself is hairy, replace the hairing, if too much hairing, and make a full inspection belt after finishing the goods.

3. The weft needle is damaged by changing one piece or punching with gauze; the steel buckle is damaged by punching with gauze or changing another steel buckle; the brown filament is damaged or the stop piece is damaged and replaced.

V. Size

Causes of formation:

1. The uneven thickness of raw materials makes the ribbon big or small. 2. The steel buckle is too big or too little to make the ribbon size.

3. Loosening of weft wheel during operation. 4. Weft rod spring with yarn wool in it.

Preventive measures:

1. The width of the ribbon should be regularly measured. When it is found that it is not up to standard, it should be adjusted immediately. 2. The steel threading should not be too big or too small. If it is not up to standard, it should be re-worn. 3. The fixed weft wheel should not be forced to be tightened. 4. The spring outside should be loosened frequently so that the yarn wool inside can come out.

6. Yin and Yang

Causes of formation:

1. Material colour difference. 2. Uneven Pressure of Plate Head 3. Uneven Puncture of Steel

Preventive measures:

1. Change the hair or the head of the plate. Do not use 2. Press the head of the plate heavily. 3. Set the weft needle position in the middle of the opening.

Seventh, jumping needle

Causes of formation:

1. The needle bar is not well blocked. 2. The position of weft and knitting needles is not right.

Preventive measures:

1. Relying on the position of the stop needle rod to carry the knitting needle 2. Aiming at the weft knitting and knitting in good position, the weft yarn can be hung up completely.

VIII. Treatment of Easy Dirty Belt

Causes of formation:

1. Brown filaments are too dirty 2. All shafts are too dirty 3. All places where yarns pass are not clean enough.

Preventive measures:

1. Accessory room collar, tissue paper and chalk, wipe off the brown silk. 2. Clean all the shafts. 3. Clean all the places where the yarn passes and where it can be touched.

9. Waves on both sides

Reasons for formation: 1. Uneven steel threading, small yarns on both sides, more yarns in the middle, too small steel threading

Preventive measures:

1. Choose the right steel buckle and wear it according to the normal wearing method. 2. Suitable for steel buckle. Don't wear it too big or too little.

X. Lines

Causes of formation:

1.
