Dyeing processes

Textile dyeing process

Original material

Original material

Received original materials are sewn, singed, and desized to the necessary quantity.

Scouring and bleaching

Scouring and bleaching

Removal of grease and various pigments in the natural fibers, as well as grease stains, pigment stains, etc. from the spinning process.

Silkete

Silkete

Improvement of luster by enhancing the cotton’s size stability and dyeing compatibility through alkali treatment of the material.

Dyeing

Dyeing

Adding and drying the mixed dyes to achieve the designated hue, and setting it with heat.

Resin treatment

Resin treatment

Resin treatment is conducted to provide the texture and functionality requested for the finished product.

Finishing

Finishing

Setting (tentering) the designated finished material, and pre-shrinking it (sanforization).

Textile inspection

Textile inspection

Inspection for fabric and processing flaws, and providing a grade (A grade, B grade, C grade).

Shipping

Shipping

The inspected material is wound, packed, and shipped.

Artificial leather dyeing process

Original material

Original material

The received original material is cut to the necessary quantity, and divided and dropped off to a dolly.

Pre-treatment

Pre-treatment

Chemicals are added so that the dye enters the inside of the original material, and thick sections of the material are pre-dyed.

Dyeing

Dyeing

The mixed dyes are added to achieve the designated hue.

Drying

Drying

The water used during dyeing is removed and the material is dried.

Post-treatment

Post-treatment

Chemical treatment is conducted to yield functionality and texture.

Finishing

Finishing

Process to produce the texture, feel, and sheen requested for the final product.

Material inspection

Material inspection

Inspection of the original material flaws and processing flaws, and judgment of whether there was success or failure.

Shipping

Shipping

The inspected material is wound, packed, and shipped.

Seishoku’s original processing

  • It is possible to have mixed weave processing with cotton for the warp and polyester for the weft. This new dyeing technique is performed once and is environmentally-friendly (in terms of energy and water resources).

  • A silky, springy texture. This processing yields material that is gentler on skin through silk’s moisturizing and insulating components.

  • It is available for mixed polyester/cotton items. A tasteful dyed feel with unique uneven dyeing.

  • It achieves over 90% deodorization after the first wash and after 10 washes for ammonia, acetic acid, and isovaleric acid. This is an advanced deodorization process.

  • Peach texture that can only be produced through careful paper nap-raising. The nap-raising produces a texture just like peach fuzz.

  • Supple texture unlike anything before through polyester quantity reduction processing. It is also possible to combine with UBUGE and CLOSPEC.

Other function processes and special processes

  • Anti-bacterial processing and odor-resistant processing

    Suppresses bacteria that feed off of sweat, grease, and waste products. It controls unpleasant odors produced by the bacteria’s secretions.

  • Antibacterial processing

    Suppresses proliferation of bacteria such as staphylococcus aureus, e. coli, Klebsiella pneumoniae, and MRSA bacteria. It is for medical and nursing care.

  • Sweat-absorption, quick-drying processing

    Improves the feel of clothes with high sweat-absorption and quick-drying properties.

  • Easy care

    Effective for shape retention of cotton/polyester textiles. It enhances the ability to simply wash and wear cotton fabrics, and suppresses shrinkage.

  • Thermal storage processing

    Creates pleasant warmth by changing sunlight infrared rays into thermal energy.

  • Springy texture processing

    Produces a firm, resilient, springy texture in fabric.

  • UV reduction processing

    Protects skin by effectively reducing UV rays.

  • Waterproof surface processing

    Applies waterproof processing to only the surface of the fabric without reducing breathability, aiming for comfort through absorption of liquid such as sweat from the inside.

  • Anti-stain processing

    Makes water and oil-based staining difficult to occur and easy to clean off.

  • Deodorization processing

    Reduces unpleasant odors with its effective reduction of odor components.

  • (Ultra) waterproof processing

    Boosts water repellency and even stain resistance without reducing breathability. Ultra-waterproof processing maintains water repellency for a long time, and offers excellent durability for washing.

  • FD processing

    Our signature processing to create a used feeling. Various appearance changes for items are possible through washing.

  • Cooling processing

    Produces a refreshing coolness through cooling effects due to an endothermic reaction.

  • Other

    We also offer various other kinds of special processes.
