Backpack khoom siv technology
Vim tias cov hnab ev ntawv yog siv rau hauv ib puag ncig tshwj xeeb, muaj cov kev xav tau siab rau cov ntaub ntawv thiab cov txheej txheem. Tag nrho cov hnab ev ntawv uas muaj kev ntxhov siab yog sewn peb zaug siv lub tshuab xaws nrog rab koob rov qab stitch, ua rau txoj haujlwm nyuaj siab thiab ruaj khov. Lub buckle thiab lwm yam khoom ntawm lub hnab ev ntawv tuaj yeem tiv thaiv kom khov, tawg, thiab deformation ntawm 120 degrees Celsius yam tsis muaj kev puas tsuaj. Cov ntaub ntawv sab nrauv ntawm lub hnab ev ntawv feem ntau suav nrog 420D Oxford nylon, 1000D nylon, 600D lossis 1000D polyester, lossis 1000D CORDURA cov ntaub ntawv. Cov khoom siv 1000D muaj qhov ntom ntom ntom thiab yog cov kev tiv thaiv heev-tiv taus, ua rau nws haum rau kev siv sab nraum zoov. CORDURA yog ib lub npe nrov qib siab hnav-tiv taus nylon roving ntaub tsim los ntawm DuPont Tuam Txhab hauv Tebchaws Meskas. Kev puas tsuaj ntawm cov khoom no yog ntau dua li cov nylon zoo tib yam lossis polyester, thiab nws yog qhov hnyav. Ntau tshaj 90 feem pua ntawm cov hnab ev khoom ntawm cov npe nrov hauv ntiaj teb siv cov khoom nylon nto moo no. Cov ntaub ntawv no tuaj yeem tiv taus dej siab ntawm 0.5 m txog 2 m kom cov ntsiab lus ntawm lub hnab kom qhuav. Qee cov ntaub ntawv kuj muaj cov kua muag resistant, yog li ib zaug punctured, lub kua muag yuav tsis tsim kua muag thiab nthuav.
