Jacquard tau txhim kho li cas

Jacquard tau txhim kho li cas?

Kev lig kev cai, graphic designs tau ua rau ntawm lub tub rau khoom. Cov heals uas yuav tsum tau rub tawm thaum kawg ntawm warp yog manually xaiv los ntawm tus neeg teb xov tooj thib ob, tus tub rau khoom, tsis yog tus weaver. Kev ua haujlwm qeeb thiab siv zog- hnyav, thiab qhov nyuaj ntawm cov qauv tsuas yog txwv los ntawm qhov ua tau zoo.

Nyob rau hauv lub thib ob ib nrab ntawm lub xyoo pua 15th, Jean le Calabrais tau tsim thawj tus qauv ntawm jacquard loom. Nws tau qhia ib hom tshiab ntawm lub tshuab muaj peev xwm ua cov xov paj sai dua thiab meej dua. Kev txhim kho rau lub loom tau mus rau ntau xyoo.

Lub tshuab kos duab tau txhim kho hauv xyoo 1725, thaum Basile Bouchon tau qhia txog lub hauv paus ntsiab lus ntawm kev siv daim kab xev perforated. Daim ntawv yob sib law liag yog xuas tes ua, segmented, txhua tus sawv cev rau ib lub lash lossis tread, thiab qhov ntev ntawm yob yog txiav txim los ntawm tus naj npawb ntawm txhaj tshuaj ib zaug ntawm tus qauv. Tom qab ntawd lub tshuab jacquard hloov zuj zus los ntawm txoj kev no.

Joseph Marie Jacquard saw that a mechanism could be developed to produce complex patterns. He may have combined mechanical elements from other inventors, but it was certainly innovative. His machine was credited for being fully perforated in each of its four sides - a modification that allowed him to increase the machine's computing power. In his first machine, he supported the harness with knotted rope and lifted it with a separate trap board.

The term "jacquard loom" is somewhat inaccurate. It is the "Jacquard head" that adapts to many dobby looms that allows the looms to create the complex patterns commonly found in jacquard weaving.

Jacquard-tsav looms, txawm tias muaj ntau dua hauv kev lag luam textile, tsis zoo li dobby looms, uas feem ntau sai dua thiab pheej yig dua rau kev khiav lag luam. Txawm li cas los xij, dobby looms tsis tuaj yeem tsim ntau cov ntaub sib txawv ntawm ib lub xov paj warp.

Niaj hnub nimno Jacquard machines yog lub computer tswj thiab muaj peev xwm muaj ntau txhiab tus hooks es tsis txhob ntawm cov thawj punch phaib.

Threading lub tshuab jacquard yog qhov nyuaj heev uas ntau lub looms tsuas yog xov nws ib zaug. Tom ntej no warp threads yog muab khi rau hauv cov uas twb muaj lawm nrog kev pab los ntawm ib tug knotting neeg hlau, uas ties txhua tshiab xov ua ke ntawm tus kheej. Txawm tias me me looms nrog tsuas yog ob peb txhiab warp threads, cov txheej txheem rethreading tuaj yeem siv sijhawm ntev.

Keeb kwm jacquard cov cav tov yog cov neeg kho tshuab, nrog cov ntaub tsim khoom khaws cia hauv cov ntawv xuas nrig ntaus ntawv uas tau txuas los ua cov saw txuas txuas ntxiv. Jacquard tshuab feem ntau yog me me thiab tsuas tuaj yeem tswj tus kheej ntawm tus lej tsawg ntawm warp xaus. Qhov no yuav tsum tau ntau repetitions nyob rau hauv tag nrho cov dav ntawm lub loom. Lub tshuab muaj peev xwm loj dua, lossis siv ntau lub tshuab, tso cai rau kev tswj kom zoo dua thiab rov ua dua tsawg dua, yog li cov qauv tsim loj tuaj yeem woven hla tag nrho cov loom dav.
