Objects of Project


Fabric Faults/Defects:

Common Defects of Fabrics during manufacturing process includes back fabric seam impression, birds eye, bowing, broken colour pattern, colour out, colour seamrs, crease mark, drop stitching, dye streak in printing, hole, jerk in, knots, mixed yarn, mottled, needle line, open reed, pin holes, press off etc.

Fabric Faults are two types

1. Knitting Faults.2. Weaving Faults.



Introduction


Knitting Faults:

A defect in the knitted fabric is an abnormality, which spoils the aesthetics i.e. the clean & uniform appearance of the fabric & effects the performance parameters, like; dimensional stability etc.There are various types of defects, which occur in the Knitted fabrics of all types, caused by a variety of reasons. The same type of defects may occur in the fabric, due to a variety of different causes e.g. Drop Stitches, Spirality.




Garments Faults/Defects:Garments Defects are classified within the following categories: Critical Defect: A serious defect that can cause harm or injury to the user and/or result in a hazardous condition. Major defects: A defect that falls to meet the mandatory regulations directly affecting the usability, stability, safety and value of the merchandise or as specified by customer buyer are considered as major defects and are generally non repairable for example fabric hole, shading among panel, wrong measurement, foreign yarn, dye patches etc.

Minor Defects: A defect that does not adversely affect the usability of the product but does consists of a deviation from the original sample, and may affect the sale of the product. Some of these defects are due to workmanship




Faults name Causes Remedy 1. Barre Caused by mixing yarn on feed

into machine. Proper yearn selection and proper roller adjustment.

2. Broken Colour Pattern Usually caused by color yarn out of place on frame.

Proper adjustment of color and yarn.

Knitting Faults Causes & its Remedies




Faults name Causes Remedy 3. Crease mark Its create when fabric passing

through squeeze rollers in the dyeing process. Its mainly Occurs in tubular knits fabric.

Proper adjustment of squeeze rollers.

4. Hole caused by broken needle Change the needle.

5. Needle Line Caused by broken needle forming distorted stitches

Replace the needle




Faults name Causes Remedy

6. Runner Usually caused by broken needle.

Change the needle.

7. Slub (Knit fabric) Usually caused by a thick or heavy place in yarn

Replace the yarn cone to a more uniform yarn cone.




Dyeing, printing and finishing faults Causes and Its remedy

Classification of Defects Major Defect• A defect that, if conspicuous on the finished product, would cause the

item to be a second. (A "second" is a garment with a conspicuous defect that affects the salability or serviceability of the item.

Minor Defect• A defect is defined as minor Defect that is not likely to reduce the Usability

of the product, but nevertheless may negatively influence the sales.• The minor defects can be untrimmed thread-ends, slight dirt in a non-

noticeable zone which can be removed, etc




Faults name Causes Remedy 1. Barre Its horizontal shaded band

across the width of the fabric. It causes by the yarn mixing

proper yarn selection.

2. Bleeding improper dye selection or poor dye fastness.

proper dye selection.

3. Crocking It is the rubbing off of the color.It may rub onto another fabric.

proper dye selection.

barre Bleeding Crocking




Faults name Causes Remedy 4. Shading It is generally due to uneven

tension on the fabric.To maintain the proper tension

5. Color variation in yarn Caused due to lack of agitation in the dye bath

proper agitation in the dye bath.

6. Crack or miss alignment in transfer printed fabric.

Incomplete transfer of design from paper to fabric

Proper transfer of design.



Shading Color variation yarnCrack


Faults name Causes Remedy 7. Creasing Causes unleveled penetration of

dyes To use proper dyes and chemical or leveling agent.

8. Flushing/Wicking Caused due to Low viscosity of print paste

To use high viscosity of printing past

9. Decolorized patch on fabric Caused due to chemical spillage on fabric. Localized excess bleaching. Localized excess enzyme wash.

To using spot cleaner.



Creasing Flushing Decolorized patch on fabric

Faults Name Causes Remedy 1. Misprints or off registration. not properly cleaning of Printing

screens .Properly Cleaning of printing screen.

2. Grease/ Oil / dirty stains. Oil stains generally come from sewing machines; machines such as over lock and flat lock machines are more prone to have oil stains.

To use spot cleaner chemical

3. Needle damage. using the wrong needle. Repairing or alter the garments

4. Open or broken seams improper handling of the cut piece or machine

Repairing or alter the garments.

Open or broken seamMisprint Grease/ oil/ dirty stain. Needle damage




Faults name Causes Remedy 5. Broken stitch improper handling of cut pieces

or improper machine usage.Repairing or alter the garments

6. Skipped or dropped stitches improper handling of cut pieces or improper machine usage.

Repairing or alter the garments

7. Neck shape. caused by defective cut pieces. Repairing or alter the garments or use proper cut piece of garments.

8. Sewing thread not matching. To use improper sewing thread. To use proper sewing thread.

Broken stitch Skipped stitch Neck shape Sewing thread not matching




Faults name Causes Remedy 9. Seams not aligned at crossing of seams.

improper handling of the cut piece.


10.Stripes not matching. from improper handling of cut pieces.


11.Misplaced label improper placement of labels when sewing

Repairing or alter the garments or proper placement of the label.

Seam not aligned at crossing of seams Stripes not matching Misplaced label




Metal Detection Machine:

Metal Detection machine is a machine which is detected the metal in the Garments. When the Garments were full completed, then it is passes throw the finishing section. Then the Garments were packaging and it is send the final inspection. The final inspection process is Metal Detection. The packed Garments were passes throw the Metal Detection machine. When the machine was found the metals, then the red button is on. Many metals such as, Pin, Needle, or any other metals.




Conclusion

In Bangladesh the maximum dyeing industry are knit dyeing

Industry. So these kinds of industries are often suffering by these

Faults which tend to not fulfill the target of production. As a

result the production capacity of these industries falls significantly.

These are the common faults which I have tried to find out the

causes & their Remedies against them.
