Problems solved by technology

Jute products are mostly used in food, coffee beans, tobacco leaf packaging, etc. The mineral oil or inorganic salts left in the jute products will cause different degrees of pollution and damage to humans, animals and the environment; some decorative hemp products have to go through Bleaching and dyeing processing requires deoiling chemical treatment before bleaching and dyeing, which not only increases costs and reduces efficiency, but also causes further pollution to the environment

Embodiment 1

[0018] Jute textile process fiber pretreatment method of the present invention comprises the following step conditions:

[0019] a. Water spraying for initial combing: the fiber of the hemp sliver passes through the stretching equipment, and sprays water on the running hemp sliver from the top between the hemp roller and the coiler. The weight ratio of the water spray to the hemp is 3%;

[0020] b. First combing and then water spraying: comb the hemp sliver fibers treated by the above steps, and spray water on the running hemp sliver from the top between the hemp roller of the first carding machine and the coiler. The weight ratio of water spray amount and hemp is 8%;

[0021] c. Stacking: Stack the flax fiber processed through the above steps, and arrange the rolls closely, and cover it with linen to prevent water loss. The stacking density is 300 kg / m3, and the stacking is 4 days in summer;

[0022] d. Re-carding at low speed: re-carding the hemp sliver fibers processed thr...

[0024] Jute textile process fiber pretreatment method comprises the following step conditions:

[0025] a. Water spraying for initial combing: the fiber of the hemp sliver passes through the stretching equipment, and sprays water on the running hemp sliver from the top between the hemp roller and the coiler. The weight ratio of the water spray to the hemp is 5%;

[0026] b. First combing and then water spraying: comb the hemp sliver fibers treated by the above steps, and spray water on the running hemp sliver from the top between the hemp roller of the first carding machine and the coiler. The weight ratio of water spray amount and hemp is 10%;

[0027] c. Stacking bins: Stack the flax fibers processed through the above steps, and arrange the flax rolls closely, and cover them with linen cloth to prevent water loss. The stacking density is 350 kg / m3, and the stacking time is 9 days in winter;

[0028] d. Re-carding at low speed: re-carding the hemp sliver fibers processed thr...

Abstract

The invention discloses a fiber pretreating method of a jute spinning process. The method includes the steps: passing jute strip fibers through a spreading device, and spraying water right above to jute strips in operation between a jute outlet roller and a coiling device by a ratio of water spraying quantity to jute weight of 3-5%; spraying water right above to jute strips in operation between a jute outlet roller and a coiling device of a first carding machine by a ratio of water spraying quantity to jute weight of 8-10%; stowing the jute strip fibers treated by the steps with the stowing density of 300-350 kilograms / cubic meters for 4-6 days in summer and 6-9 days in winter, closely arranging jute rolls, and covering jute cloth on the jute rolls to prevent water desorption; carding by a carding machine at a cylinder speed of 156.1-165.2 revolutions per minute, by a ratio of working roller speed to cylinder speed of 42, in the gauge length between a working roller and a cylinder of 3.6-4.2 millimeters, in the draft multiple of 10-11, and in the feeding gram weight of 1200-1400 grams / meters.

Description

technical field [0001] The invention relates to a jute fiber processing method, in particular to a jute textile fiber pretreatment method. Background technique [0002] Jute textile process fiber pretreatment is an important process of jute textile. The existing jute textile fiber pretreatment method is to add 4-7% mineral oil and 0.2-0.5% emulsifier for oil treatment and then carding to meet the needs of spinning and weaving technology. A small number of enterprises switch to vegetable oil agents according to user needs, and a small amount of preservatives such as zinc chloride must be added to the vegetable oil pretreatment process. Jute products are mostly used in food, coffee beans, tobacco leaf packaging, etc. The mineral oil or inorganic salts left in the jute products will cause different degrees of pollution and damage to humans, animals and the environment; some decorative hemp products have to go through Bleaching and dyeing processing requires deoiling c...
