Cov khaub ncaws sab nrauv feem ntau yog ua los ntawm cov khoom siv tshuaj fiber ntau. Thaum qhov chaw sab nraum zoov qhuav heev, cov teeb meem hluav taws xob zoo li qub tuaj yeem tshwm sim, pom tau tias cov khaub ncaws ua rau fuzzing thiab pilling, ua rau plua plav thiab av, thiab tsim hluav taws xob zoo li qub adsorption ze ntawm daim tawv nqaij. Yog tias nqa cov cuab yeej siv hluav taws xob zoo xws li cov khoom siv hluav taws xob, lub ntsuas hluav taws xob, GPS navigators, thiab lwm yam, muaj peev xwm ua rau muaj kev cuam tshuam los ntawm electrostatic cuam tshuam los ntawm cov khaub ncaws, ua rau muaj qhov tshwm sim loj.

Antistatic fabrics muab faib ua ob hom: tsis ruaj thiab ruaj. Cov kev sim uas nquag siv nyob rau hauv Suav teb suav nrog static voltage ib nrab-lub neej txoj kev, zoo li qub tus nqi nto ntom ntom, thiab tus nqi them tus nqi. GB/T12703 "Kev ntsuam xyuas ntawm Electrostatic Properties of Textiles" suav nrog 7 ntu, ntawm 3 qhov tau ua tiav, thiab qhov seem tseem nyob hauv txoj kev txhim kho. Lub hauv paus ntsiab lus ntawm GB/T12703.1 "Kev ntsuam xyuas ntawm cov khoom siv hluav taws xob electrostatic ntawm textiles - Ntu 1: Static voltage ib nrab-lub neej" yog ua kom cov qauv them rau lub xeev ruaj khov nyob rau hauv high-voltage electrostatic teb, disconnect qhov siab. -voltage fais fab mov, thiab cia nws voltage ib txwm lwj los ntawm ib tug grounded hlau platform. Lub sij hawm xav tau rau nws qhov hluav taws xob tawg mus rau ib nrab ntawm tus nqi pib yog ntsuas hauv vib nas this, thiab tus nqi me me qhia tau tias kev ua haujlwm zoo li qub. Tus qauv qhia tias qib qis dua lossis sib npaug rau 2.0s, qib b Tsawg dua lossis sib npaug rau 5.0s, thiab qib c Tsawg dua lossis sib npaug rau 15.{{31} }s. Rau cov ntaub ntawv uas tsis muaj kev tiv thaiv zoo li qub, qhov yuav tsum tau ua ua ntej ntxuav; Rau cov khoom siv tiv thaiv zoo li qub, qhov yuav tsum tau ua ua ntej thiab tom qab ntxuav. Lub hauv paus ntsiab lus ntawm GB/T12703.2 "Kev ntsuam xyuas ntawm cov khoom siv hluav taws xob electrostatic ntawm textiles - Ntu 2: Charge deg ntom ntom" yog los ntxig cov qauv uas tau muab rub los ntawm cov khoom sib txhuam rau hauv Faraday lub tog raj kheej los ntsuas cov nqi ntawm qhov ntom ntom ntawm tus qauv. Txoj kev siv hluav taws xob ntawm txoj kev no qhia txog qhov tseeb ntawm kev sib txhuam hluav taws xob ntawm cov ntaub thaum hnav, thiab cov txheej txheem tev tawm zoo ib yam li cov txheej txheem stripping, uas tuaj yeem cuam tshuam qhov muaj peev xwm ntawm corona tawm ntawm cov ntaub thaum hluav taws xob. Nws yog qhov tsim nyog rau kev soj ntsuam cov ntaub ntawv tiv thaiv zoo li qub nrog cov xov hlau txuas ntxiv, tab sis cov txiaj ntsig kev sim yuav raug cuam tshuam los ntawm tib neeg cov yam ntxwv thiab txoj hauj lwm ntawm cov ntaub ntawv kuaj hauv cov txheej txheem electrostatic. Qhov me me ntawm tus nqi ntawm qhov ntom ntom, qhov zoo dua qhov kev ua haujlwm zoo li qub. Cov qauv yuav tsum tsis txhob siv cov ntaub tsis zoo siv nrog tus nqi sib txawv sib txawv tsis dhau 7. 0 ua ntej ntxuav? C / m2; Tus nqi ntawm qhov ntom ntom ntawm cov ntaub ruaj khov ua ntej thiab tom qab ntxuav yuav tsum tsis pub tshaj 7.0? C / m2. GB / T12703.3 "Kev Ntsuas ntawm Electrostatic Properties of Textiles - Ntu 3: Charge Quantity" Lub hauv paus ntsiab lus ntawm kev ntsuas yog simulate qhov kev sib txhuam ntawm cov hluav taws xob ntawm cov qauv siv cov khoom sib txhuam, ntxig cov qauv rau hauv lub tog raj kheej Faraday, thiab ntsuas nws cov nqi taw tes. kom muaj nuj nqis. Qhov me dua tus nqi, qhov zoo dua qhov kev ua haujlwm zoo li qub. Cov txheej txheem yuav tsum tau: Cov ntaub ntawv tsis muaj zog tiv thaiv zoo li qub nrog tus nqi ntxuav ua ntej tsis pub tshaj 0.6? C / daim; Rau cov khoom siv tiv thaiv zoo li qub, tus nqi ua ntej thiab tom qab ntxuav yuav tsum tsis pub tshaj 0.6? C / daim.
Muab piv rau cov qauv hauv tebchaws thiab kev lag luam uas twb muaj lawm, cov kev ntsuas ntsuas ntawm txhua txoj kev sib txawv, thiab cov txiaj ntsig tau los ntawm kev siv cov kev sim sib txawv tsis sib piv. Txoj kev them nqi ntawm qhov ntom ntom tuaj yeem ua tau zoo simulate cov txheej txheem hluav taws xob ntawm cov khaub ncaws sab nraum zoov thaum hnav tiag tiag, thiab yog ib txoj hauv kev tsim nyog rau kev ntsuas qhov ua tau zoo ntawm cov khaub ncaws sab nraum zoov.
UV tsis kam
The evaluation parameter for textile protection against ultraviolet radiation uses the ultraviolet protection coefficient upf value, which represents the ratio of the average effect of ultraviolet radiation calculated when the skin is not protected and the average effect of ultraviolet radiation calculated when the skin is protected by fabric. GB/T18830-2009 "Evaluation of UV Protection Performance of Textiles" specifies the test methods, expression, evaluation, and identification of the UV protection level of textiles against sunlight. The testing principle is to use monochromatic or multi-color UV radiation samples, collect the total spectral transmission rays, and determine the total spectral transmission ratio t( λ), And calculate the UV protection coefficient upf value of the sample. Parallel light beams can be used to illuminate the sample, and an integrating sphere can be used to collect all transmitted light; Alternatively, a hemisphere of light can be used to illuminate the sample and collect parallel transmitted light. In practical operation, the detection instrument can automatically calculate the upf value and t of the sample( λ). When the upf value of the sample is greater than 50, it is represented as "upf>50.
