SPH fabric
Many people have misunderstandings or understanding of “SPH fabric“. Let me take you with me to share with your friends and explore more about “SPH fabric” “Knowledge…
Sph is a new type of elastic fiber filament. SPH fiber is a new type of elastic fiber that has appeared on the market in recent years. It is made by side-by-side composite spinning of two polyester compounds with different thermodynamic properties, PTT and PET, and then undergoes relaxation heat treatment to form a thin and dense fiber similar to wool. The three-dimensional structure of the crimped fiber [1~2] has a tensile resilience close to that of spandex, while its elastic durability is better than that of spandex. It is easy to dye and has good color fastness.
Compared with ordinary polyester fabrics, SPH fabrics are soft, fluffy and elastic, easy to deform when stretched, and have good tensile recovery properties after stretching and deformation. Shear deformation is easy to occur, but the shear recovery is almost the same as that of ordinary polyester fabrics. Similarly, the surface of SPH fabric is as smooth and flat as ordinary polyester fabric.
1. Polyester staple fiber
1. Distinguished by physical properties: high strength and low elongation type, medium strength and medium elongation type, low strength and medium elongation type, high modulus type, high strength and high modulus type
2. Distinguish according to post-processing requirements: cotton type, wool type, linen type, silk type
3. Distinguished by use: clothing, wadding, decoration, industrial use
4. Classified by function: cationic dyeable, hygroscopic, flame retardant, colored, anti-pilling, antistatic
5. Distinguish according to fiber cross section: special-shaped yarn, hollow yarn.
2. Polyester filament
1. Spun yarn: undrawn yarn (conventional spinning) (UDY), semi-preoriented yarn (medium-speed spinning) (MOY), pre-oriented yarn (high-speed spinning) (POY), highly oriented yarn (Ultra-high speed spinning) (HOY)
2. Drawn yarn: drawn yarn (low-speed drawn yarn) (DY), fully drawn yarn (one-step spinning and drawing method) (FDY), fully drawn yarn (one-step spinning method) (FOY)
3. Textured yarn: conventional textured yarn (TY), drawn textured yarn (DTY), air textured yarn (ATY).
Composite down silk is a new down thermal insulation product at home and abroad. The TPU film with moisture permeability function is used as the anti-down material, which is organically combined with composite shaping and down silk. It is currently a new technology product for down at home and abroad.
It uses pure natural elements. Feathers are carefully cleaned and disinfected. Complying with the national environmental protection product requirements, it uses a unique production method to spin a material like bulky cotton, and is treated with a TPU film and anti-velvet composite to become a cutable thermal insulation material.
