Sewing Thread Making Business – How To Start

How to Start Sewing Thread Making Business


Almost 95% of all sewing thread which is produced is used in commercial and industrial sewing. Sewing thread is notable from yarn by the fact that thread is used to sew together garments or other products, but the yarn is the group of fibres used to weave or knit into a textile fabric. The terms are confusing and are often seen interchangeably; thread can be made of yarn, but the yarn is not made of threads.

The three primary types of thread are based on their origin and are an animal, plant, or synthetic. Silk thread is widely popular for wools and silks (fabrics of animal origin). It is strong, very elastic, and fine. Silk is also used for tailoring, to finish the edges of buttonholes, and for sewing on buttons, and for decoration. It is very strong and can be lastingly stretched.

Cotton threads are made of the cellulose obtained from plants and are used in the stitching of fabrics like rayon, linen, and cotton that also have plant origins. Plant-based fabrics may shrink, and the cotton thread has the same shrinkage properties. Also, the cotton thread does not stretch, so it is suitable for woven fabrics but not stretchy knits. Cotton is also used to make basting thread that is needed to hold pieces of a garment together temporarily until the garment is sewn. Cotton basting thread is not costly and is loosely twisted so it can be broken easily and pulled out when permanent stitching is in place. Now, let us get into the detailed information of starting a Sewing Thread Making Business in India.

A step-by-step guide to starting a Sewing Thread Making Business

Nylon and polyester threads are recommended for synthetics and stretch knits. Both types of synthetic threads have the same characteristics including no shrinkage, high strength, and fine abilities to stretch and get well which make them suitable appropriate for knits, preshrunk fabrics, and sheers. Nylon and polyester are the only threads that are produced from a single yarn or single-ply. Nylon’s stretching characteristics and relative brittleness are troublesome, and this thread has been less famous. Synthetic threads are marketed with a variety of names popular as polypropylene, Teflon, Kevlar, and Nomex. 

The market potential of the Sewing Thread Making Business

In the future, the manufacture of the thread must remain to adapt to new categories of fabric and clothing design and production. Futurists may forecast that clothing and its varieties will become outdated; however, the reality is that the consumer desires to express personality through a closet filled with clothing for a variety of tasks. And this clothing is sewn together using specialized threads.

Raw materials required to start Sewing Thread Making Business

Silk thread

Silkworms produce cocoons that are used to manufacture silk. The female silkworms feed on mulberry leaves up to the worms mature and begin to spin cocoons. The worm secretes the silk thread through specialized glands below its mouth. It completes the cocoon around itself; over a two- to three-week duration, it becomes a pupa then a moth. The cocoons can be gathered when the pupas are still inside so that so-called nett silk can be manufactured; cocoons are also harvested after the moths have hatched, and silk from these is known as Schappe silk.

Cotton thread

Cotton is harvested from cotton plants in the field and made into large bales. The bales often comprise dirt, broken pieces of cotton boll, seeds, and other impurities, so cleaning is the first stage at the mill. The bale is broken, the fibers are undone by a comb-like device, mixed, and cleaned. The cleaned cotton fibers are known as laps. The laps are fed into a carding machine that splits the fibers. Further cleaning, combing and sorting ready fibers for processing into thread.

Polyester thread

Polyester is a petroleum product. During the cracking process, crude oil is broken down into several components that will be managed into a range of products from gasoline to plastics including polyester. Xylene, a hydrocarbon compound, is produced during cracking. Nitric acid and glycol are fed to modify the xylene through several chemical reactions. The fluid is heated and condensed using an autoclave, and the molecules align to form long molecules known as polyester. The resulting mass of threads is extracted, cooled with water as the coolant, and cut into small chips. These chips are transported from the refinery to the thread manufacturer for spinning.

Designing of the Sewing Thread

Professionals who design sewing thread are known as seam engineers. They are skilled in the practical aspects of sewing, clothing manufacture, and sewing machine operation. The manufactured thread is tested as per the actual use and conditions as per the needs in the market and hence it is verified carefully. The best thread products are required to meet the demands of new and ever-changing markets.

The manufacturing process of Sewing Thread

Nett silk

  • Cocoons comprising the pupas are heated with air to maintain the pupas inside.
  • The cocoons are placed in water and a brushing motion unwraps the silk thread; a single thread can be up to 1,000 yds (3,000 m) in length.
  • We can produce two types of silk here. Both use the cocoon of the silkworm to manufacture silk thread, however, one processes the cocoons that have the pupa, producing soft silk known as nett silk. The other utilizes cocoons that have already hatched to give rise to schappe silk. Hot air is required to make the nett silk which inhibits the growth of the pupa inside the cocoon and many yarns are wound together to give a thread. Since it is obtained using an older, hatched cocoon, schappe silk production begins with the soaking, then washing, next softening, and drying the cocoons. Next, the cocoons are sent through steel rollers with combs to give bundles of long, straight fibers of silk, which are combed, twisted, and spun into thread.
  • Several threads from the same cocoon are wound together in long loops or hanks to give a single yarn. Three of these single yarns are twisted to manufacture nett silk thread. More than three single yarns are used based on the planned use of the thread.

Schappe silk

  • Schappe silk is prepared from cocoons from which the silk moths have hatched. This matured thing is harder than nett silk cocoons and must be softened, washed, and later dried.
  • Bundles of long fibers of silk are made by passing the cocoons through steel rollers. These fibers are called combed top or peigne.  
  • To produce a brand many bundles are grouped which are then combed into a narrower band and fed through rotating rollers. The emerging yarn is gently twisted and is called the roving.
  • The roving is spun to produce a single thread, and several single threads are wound together, twisted, and fed onto a bobbin or cone.

Cotton thread

  • The fiber is carefully twisted to form roving, and the roving is pulled and twisted again.
  • It is spun to form a single thread that is wound and twisted with others to produce the thread.
  • Cotton thread is singed using an open flame and mercerized after immersing it in caustic soda. This step strengthens the thread and gives it a lustrous texture. The treated cotton thread is then wound on bobbins or cones.

Spun polyester thread

  • The chips of polyester obtained from the refinery are spun into long filaments which are bonded together to produce polyester tow. Tow contains about 170,000 continuous, fine, parallel filaments in a long band.
  • The filaments will be tested for weakness by stretching the tow is stretched to the breaking point. The weak points are removed, and fibers that are 2.5-4.75 in (60-120 mm) are obtained.
  • These resulting strong fibers are banded together again in parallel, and many bands are combined until a narrow, even, the high-quality band of parallel fibers results.
  • These bands are further stretched and slightly twisted into roving, and the roving is spun and twisted into a single thread. The drawing and twisting process will aid fibers in stretching up to 10-20 times their length in the tow stage and the spindles that are on the spinning machines which are involved will be rotating at 12,000 revolutions per minute.

Dyeing and packaging finished thread

  • All types of the thread may be finished in the same way.
  • After manufacture, the thread is dyed. The dye is mixed in large vats; Many colors can be given, and dye mixing is monitored by computer. Large cones or bobbins of manufactured thread are lowered into pressurized vessels, and the dye (and other additives) are released into the vessels using the system. After it is taking out from the dyeing vessel, the thread is dried for about 24 hours. About 6.6 tons (6 metric tons) of thread can be dyed in a single day; this equals 66 million yds (200 million m) of sewing thread or enough to circle the equator five times.
  • The dyed thread is wound on smaller spools for home or factories, and the spools are packed into boxes for transportation. Optical devices monitor the spool winding and packing steps.

Byproducts / Waste

Cotton thread production produces more waste than the manufacture of other types of thread because of the parts of the cotton that cannot be used. The volume is still comparatively minor but must be disposed of. Imperfect fibers and fiber dust are produced in the initial stages of production and, again, must be disposed of.
