example 1

[0017] Use 60Nm wet-spun hemp yarns as warp and weft yarns to produce 60Nm×60Nm×68×68×63″ wet-spun hemp flat cloth. The manufacturing method: 60Nm warp and weft yarns are all passed through automatic winding machines. The process is: short thick knots: 220% 3.0 cm; long slub: 90% 40cm; detail: -70% 59cm, relative humidity: 75%, temperature: 25℃.

[0018] The steam heat and humidity twist setting method is adopted, and the process requires a steam pressure of 8 MPa and a time of 28 minutes.

[0019] Batch warping machine is used for warping, pneumatic pressure is applied, and the warping tension is divided into four zones and three layers. Single warp yarn tension is 75cN, side warp yarn tension increases 20%, speed: 200 m / min.

[0020] The sizing is carried out on a Ben-procome sizing machine, using wet split stranding. Sizing formula: modified starch: 60%, polymethyl acrylate: 30%, polyvinyl alcohol: 10%, high sizing rate, count yarn: 10-12%, moisture regain: 7.5%, elongati...

example 2

[0024] Use 24Nm wet-spun hemp yarns as warp and weft yarns to produce 24Nm×24Nm×54×54×63″ wet-spun hemp plain cloth: the 24Nm warp and weft yarns are all passed through the automatic winder. The process is: short thick knots: 220% 3.0 cm; long thick quarter: 90% 40cm; detail: -70% 59cm, relative humidity: 70%, temperature: 22℃.

[0025] Adopt steam heat wet twist fixing method, process requires steam pressure 16MPa, time 15 minutes (or steam pressure 0.12MPa, time 30 minutes).

[0026] Batch warping machine is used for warping, pneumatic pressure is applied, and the warping tension is divided into three zones and three layers. Single warp yarn tension is 65cN, side warp yarn tension increases by 25%, speed: 300 m / min.

[0027] The sizing is carried out on a Ben-procome sizing machine, using wet split stranding. Sizing formula: modified starch: 80%, polymethyl acrylate: 20%, polyvinyl alcohol: 0%, sizing rate medium-count yarn is 7.1-9.9%, moisture regain: 6%, elongation: 0.5...

example 3

[0031] Use 7Nm wet-spun hemp yarn as warp and weft yarn to produce 7Nm×7Nm×41×30×63″ wet-spun hemp flat cloth. The manufacturing method: 7Nm yarns are all passed through ordinary winding machines, equipped with water mist air twister and electronic yarn clearing device, metal groove tube, and length fixer. The process is: short thick place: 220% 3.0cm; long thick place: 90% 40cm; detail: -70% 59cm, made into non-joint yarn, strand twist: 10 twists / inches, relative humidity: 73%, temperature: 26°C.

[0032] The yarn is placed in a humidification chamber with a temperature of 36° C. and a relative humidity of 78% (or a temperature of 32° C. and a relative humidity of 75%) for 24 hours for yarn setting.

[0033] Batch warping machine is used for warping, pneumatic pressure is applied, and the warping tension is divided into three zones and three layers. Single warp yarn tension is 95cN, side warp yarn tension increases by 22%, warping speed: 180 m / min. Inverting axis speed: 10...

Abstract

The invention belongs to the technical field of bast fibre manufacturing, more particularly relates to wet-spinning cordettes and a preparation method thereof, solving the problems of poorer fabric handfeel, more hairiness, itchy feeling to skins, and the like of dry-spinning cordettes. The preparation method of the wet-spinning cordettes comprises the following steps: spooling, twist-setting, beam-warping, slashing and weaving wet-spinning hemp yarns; a fully-automatic spooling machine or a general spooling machine is adopted in the spooling process; a steaming hot-wetting twist-setting method or a natural storage twist-setting method is adopted in the twist-setting process; batch beam-warping or sectional beam-warping is adopted in the beam-warping process, wherein the slashing process is carried out after batch beam-warping, and the yarns are directly weaved after sectional band-warping; and the slashing process adopts covering as a main step and soakage as an auxiliary step. The wet-spinning cordettes prepared by the method has excellent performances of air permeability and coolness, fast moisture absorption and release, soft and elegant handfeel, excellent fabric drapability, and the like, also has the health care functions of corrosion prevention and bacteriostasis, static resistance, radiation resistance, ultraviolet prevention, and the like, and can be widely suitable for clothes and household textile products.

Description

technical field [0001] The invention belongs to the technical field of hemp spinning, and in particular relates to a wet-spun hemp cloth and a manufacturing method thereof. technical background [0002] At present, the hemp cloth produced in our country is made of dry spinning and weaving. The cloth has more hairiness, poor hand feeling, and heavy cloth body. When people wear it, the hemp cloth woven by dry spinning will tingle the skin. . Contents of the invention [0003] The invention aims to solve the problems of poor hand feeling, more hairiness and itching on the skin of the current dry-spun hemp cloth, and provides a high-grade wet-spun hemp cloth made by using wet-spun yarn and a manufacturing method thereof. [0004] Because the wet-spun hemp yarn adopts the roving degumming process and wet spinning, the yarn is strong, but the elasticity is poor, the elongation is small, and the rigidity is high. Therefore, it is difficult to weave according to the ordinary proc...
