Production of paper yarn from cellulose-containing plant species
View Patent ↗The method disclosed relates to the production of paper yarn from cellulose-containing plant species, in the textile sector, and particularly relates to obtaining a paper yarn by a wet spinning method using high or low purity cellulose raw material isolated from the wild plant species of Calluna Vulgaris.
1. A method of obtaining yarn from an Ericaceae plant species, the method comprising:
obtaining cord or pulp strips from the Ericaceae plant species;
passing the obtained cord or pulp strips through a caustic bath;
providing saturated steam in a steaming section;
passing the cord or pulp strips through the steaming section;
adjusting a pH value in a neutralization bath;
passing the cord or pulp strips through the neutralization bath; and
spinning the cord or pulp strips after passing through the neutralization bath so as to obtain the yarn.
2. A method of obtaining yarn from an Calluna Vulgaris plant species, the method comprising:
obtaining cord or pulp strips from the Calluna Vulgaris plant species;
passing the obtained cord or pulp strips through a caustic bath;
providing saturated steam in a steaming section;
passing the cord or pulp strips through the steaming section;
adjusting a pH value in a neutralization bath;
passing the cord or pulp strips through the neutralization bath; and
spinning the cord or pulp strips after passing through the neutralization bath so as to obtain the yarn.
3. The method of claim 2 , wherein the step of obtaining cord or pulp strips comprising:
treating fiber bundles obtained from the Calluna Vulgaris under pressure in a solution containing at least one of NaOH, NaBO 3 , H 2 O 2 and MgSO 4 ;
washing the treated fiber bundles with water; and
dividing the washed fiber bundles into the cord or pulp strips.
4. The method of claim 2 , wherein the step of obtaining cord or pump strips comprising:
retting, scutching, hackling, stripping and roving to a stem of the Calluna Vulgaris.
5. The method of claim 2 , wherein the step of passing the cord or pulp strips through the caustic bath comprising:
passing the obtained cord or pulp strips through a sodium hydroxide solution in the caustic bath.
6. The method of claim 2 , wherein the step of passing the cord or pulp strips through the caustic bath comprising:
positioning rollers, feed rollers and spinning rollers successively in the caustic bath;
spinning and orienting the cord or pulp strips with the positioned rollers, feed rollers and spinning rollers in the caustic bath.
7. The method of claim 2 , wherein the step of passing the cord or pulp strips through the steaming section comprises:
treating the cord or pulp strips with the saturated steam for 20 to 60 minutes in the steaming section.
8. A method of obtaining yarn from a cellulose-containing plant, the method comprising:
obtaining cord or pulp strips from the cellulose-containing plant;
passing the obtained cord or pulp strips through a caustic bath;
providing saturated steam in a steaming section, the steaming section having grooved or hexagonal transfer rods;
passing the cord or pulp strips through the steaming section;
adjusting a pH value in a neutralization bath;
passing the cord or pulp strips through the neutralization bath; and
spinning the cord or pulp strips after passing through the neutralization bath so as to obtain the yarn.
9. The method of claim 8 , wherein the grooved or hexagonal transfer rods have independently operable drives.
10. The method of claim 8 , further comprising:
checking the pH value of the cord or pulp strips; and
adjusting the pH value to 5-7 in the neutralization bath.
