H.T.Polyester filament sewing thread

　　High performance and high strength polyester filament yarn is made of high strength continuous filament polyester yarn before stabilization.

　　High performance high strength polyester long thread provides good wear resistance for all types of leather. Soft surface with excellent low friction lubrication, reduce needle heat and wear effects.

　　High performance high strength polyester filament with high breaking strength and optimum tensile properties can be used in leather shoes and leather products with high requirements.

The main purpose

　　● decorative glove sports equipment

　　● upholstered mattress and bedding

　　● zipper outdoor goods leather accessories shoes

Characteristic and advantages

　　1, high strength polyester long thread is a kind of high tenacity polyester sewing thread, better than nylon or polyamide sewing thread on UV resistance

　　2, the high strength of fine yarn ensure the shoes category special fine seam demand can be met

　　3, high strength polyester long thread has a special lubrication formula, can provide excellent friction resistance on high-speed sewing machines

　　4, good extension characteristics to produce excellent sewing effect, and on the surface of multiple leather to create a tight and firm seam

　　5, high strength polyester long silk thread can form a good loop, so that the seam appearance more neat, beautiful

Physical and chemical properties

Thermal properties:

● thermal melting point at 250 to 260 degrees Celsius softening point at 220 to 240 degrees Celsius

● at a temperature of 150 degrees Celsius, the degree of contraction is less than 1%

Thermal properties:

● thermal melting point at 250%C, adhesion at 229C

Chemical properties:

● inorganic acid: weak acid resistance; But it breaks down in strong acids

● alkaline: in the case of weak alkali is not affected, in strong alkali, especially in the case of high temperature will have a greater impact on the durability

● organic solvents: generally unaffected, but soluble in compounds containing benzene

● rinse: not affected.

● insects/microorganisms: not affected(mold, rot)

● moisture absorption rate: about 4.5%

Color fastness characteristics:

● washing colour fastness to 60 ° C. (ISO 105 c10:2006 C(3)) grade 4

● Color fastness to water pressure. (ISO 105 e01:2010) grade 4

● colour fastness to abrasion (ISO 105 X12:2001) grade 4

● colour fastness to bleaching. (ISO 105 n01:1993) grade 4

● color fastness to dry cleaning. (ISO 105 e01:2010) grade 4

● colour fastness to perspiration. (ISO 105 e04:2009) grade 4

● colour fastness to light. (ISO 105 b02:1994) grade 4

The color fastness grade depends on the most basic expression, in fact, most colors are beyond this range.
