1. Structural design: from overall rigidity to independent response Compression spring adopts a manufacturing process of continuous winding of a single steel wire, and all springs are connected in series through spiral iron wire to form a rigid mesh system (such as Bonnier spring). This integrated design makes adjacent springs highly coupled – when one place is under […]
When we sink into a soft mattress for a night’s sleep, few people realize that what really supports this comfort and health are countless precision-designed and high-performance spring steel wires. They are the invisible skeleton of the mattress, and the difference in their parameters is enough to subvert the quality of sleep and the durability of […]
1. Material: Double game between luxury and practicality The core value of leather sofas comes from the leather grade: First-layer cowhide (especially yellow cowhide) retains natural pores and has excellent breathability. The surface temperature in summer is 2-3℃ lower than that of fabric, but the cost accounts for 35%-40% of the total product price; Second-layer leather has […]
1. Cleaning tools: accurate selection, twice the result with half the effort The choice of cleaning tools and dosage forms is directly related to the life and effect of leather. For daily floating dust, dry wiping with a microfiber cloth is the first choice to avoid friction damage with ordinary rags (the International Leather Crafts […]
1. Material grade and comfort science The core of the quality of handmade leather sofas lies in the type of leather：– Full-grain first layer skinRetains natural pores and texture, and has the best breathability. Experiments have proved that its surface temperature is 2-3℃ lower than that of fabric, and it feels more comfortable in summer.-Semi-green […]
1. Fabric: The cornerstone of touch and life, not just “leather” and “cloth” The fabric is the outer coat of the sofa, and it is also the first line of defense for comfort and durability. Distinguishing genuine leather: Luxury genuine leather sofas hide the mystery of grade. Beware of the myth of “NAPPA leather” – it […]
1. Ehtne nahk: luksusliku tekstuuri pärija, kahekordne lubadus vastupidavusest ja stiilist Tippklassi ehtsast nahast diivanid on valitud kvaliteetsetest loomanaha embrüotest, nagu lehmanahk, ja need esitavad unikaalseid tekstuure ja loomulikku hingamist läbi mitme range protsessi. Selle suurepärane plastilisus ja hingavus toovad võrratu nahasõbralikkuse kogemuse. Ameerika nahkliidu andmed [...]
2.Nahk: ehtsate materjalide õilsus ja vastupidavus Nahk annab pehmetele vooditele asendamatu tekstuuri ja väärtuse. Tipptasemel pehmed voodid kasutavad sageli Itaalia imporditud kollast lehmanahka, mille loomulikud ebakorrapärased mustrid ja armid on puhta vere märk. Sellisel nahal on tipptasemel hingavus (talvel soe ja suvel jahe), suurepärane kulumiskindlus (ei [...]
1. Nahaklass: "täisnaha" ja "komposiitnaha" vahelise olulise erinevuse paljastamine 1.1 Nahkade liigitusstandardid Täisnahk: säilitab loomuliku poorsuse, tippklassi materjal, mille on sertifitseerinud autoriteetne organisatsioon ILPA ([International Leather Craftsmen Association]) Korrigeeritud tera: pinna poleerimine, vastupidavus on suurenenud 30%, kuid hingavus vähenenud Liimitud nahk: taaskasutatud materjalide ühendamine, ELi määrused näevad ette [...].
Käesolevas artiklis analüüsitakse ELi REACH-määruste ja USA ASTM D3574 katsestandardi alusel süstemaatiliselt 8 peamise materjali, näiteks suure tihedusega käsna ja mäluvahu, molekulaarstruktuuri erinevusi. Võrreldes Saksa LGA labori 20-aastase vastupidavuse katseandmeid Jaapani JIS S 1101 kodustandardiga, on salajane [...]
