Ho fokotsa kapa ho thibela ho ata ha fiber, mehato e latelang e ka nkuoa:

1. Fokotsa tekanyo ea dae e ntšo ea sebabole: tekanyo ea dae e khethehileng ea mercerizing e khethehileng e ke ke ea feta 700 G / package.

2. Ka mor'a ho daea, hlatsoa ka ho feletseng ka metsi ho thibela 'mala o phaphametseng hore o se ke oa bola ho ba asiti ea sebabole nakong ea polokelo.

3. Sebelisa li-anti-tender treatment agents, tse kang urea, soda ash, sodium acetate, joalo-joalo.

4. Tekanyo ea khoele e betliloeng ka metsi e tlase ho feta ea khoele e betliloeng ka alkaline.

5. Omisa khoele e dailoeng ka nako ho qoba ho futhumala ha khoele e metsi ha u ntse u bokellana, e leng se bakang phokotso ea li-anti-brittleness agent le boleng ba pH.
