Summary
This summary is machine-generated.This study explores polyethylene terephthalate (PET)/copolymer-PET (Co-PET) hollow yarns with inorganic particles. The KFD PET/Co-PET fabric offers excellent moisture management and heat retention for winter clothing.
Area Of Science
- Textile Science and Engineering
- Materials Science
- Polymer Science
Background
- Developing advanced textile materials with enhanced properties is crucial for performance apparel.
- Polyethylene terephthalate (PET) and its copolymers (Co-PET) are widely used in textiles, but their comfort properties can be improved.
- Incorporating inorganic particles into bicomponent yarns offers a route to modify yarn and fabric characteristics.
Purpose Of The Study
- To investigate the spinning and wear comfort properties of PET/Co-PET hollow yarns.
- To evaluate the effect of inorganic particle type and concentration on yarn and fabric performance.
- To identify optimal yarn compositions and processing conditions for specific applications.
Main Methods
- Fabrication of three sheath/3-core bicomponent yarns using PET/Co-PET with embedded inorganic particles (TiO2 and CaCO3).
- Assessment of spinnability, tenacity, and breaking strain under determined optimal spinning conditions.
- Evaluation of fabric hollowness ratio, moisture management system (MMT) properties, heat retention, and tactile hand feel.
Main Results
- All developed bicomponent yarns demonstrated good spinnability and weavability with satisfactory mechanical properties.
- The Kolon calcium carbonate (KCC) PET/Co-PET fabric exhibited the highest hollowness ratio, attributed to higher CaCO3 content and larger particle size.
- The Kolon full-dull (KFD) PET/Co-PET fabric showed superior moisture management (absorption and drying) and heat retention, suitable for winter wear.
- KFD and KCC/Co-PET fabrics offered a softer tactile feel compared to Kolon semi-dull (KSD) PET/Co-PET fabric, though KCC showed potential durability concerns.
Conclusions
- PET/Co-PET bicomponent hollow yarns with embedded inorganic particles can be successfully produced with good spinnability and mechanical strength.
- The type and amount of inorganic particles significantly influence the hollowness ratio and comfort properties of the resulting fabrics.
- The KFD PET/Co-PET fabric is particularly promising for winter clothing due to its excellent moisture management, heat retention, and soft feel, while KCC PET/Co-PET fabric requires further investigation regarding durability.

The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...
In bromoethane, the three methyl protons are coupled to the two methylene protons that are three bonds away. In accordance with the n+1 rule, the signal from the methyl protons is split into three peaks with 1:2:1 relative intensities. The methylene protons appear as a quartet, with the relative intensities of 1:3:3:1.
Qualitatively, any spin plus-half nucleus polarizes the spins of its electrons to the minus-half state. Consequently, the paired electron in the hydrogen–carbon bond must...
Copolymers are the products obtained from the polymerization of multiple monomer species. So, in a polymer chain itself, there can be multiple repeating units that come from different monomers. The process of synthesizing a polymer from different monomer species is called copolymerization. When two monomers are involved, the polymer is known as a bipolymer. Polymers with three and four monomers are termed terpolymers and quaterpolymers, respectively. Figure 1 depicts the copolymerization of...
Polymers that are made up of identical monomer units are called homopolymers. Only one repeating unit is involved in the construction of the homopolymer structure. For example, as depicted in Figure 1, polypropylene is a homopolymer constituted of propylene monomers. Here, the only repeating unit in the polymer chain is propylene.

The chemical name of a homopolymer is generated by using the name of its monomer with a prefix ‘poly’....
Coupling interactions are strongest between NMR-active nuclei bonded to each other, where spin information can be transmitted directly through the pair of bonding electrons. While nuclei polarize their electrons to the opposite spins, the bonding electron pair has opposite spins. Configurations with antiparallel nuclear spins are expected to be lower in energy. When coupling makes antiparallel states more favorable, J is considered to have a positive value. The one-bond coupling constant, 1J,...
Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others.
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
