Problems solved by technology

Even so, the ratio of fiber sticking and silk to account for the total amount of mulberry fibers is still 32%, which not only affects the fiber yield after opening and carding, so that it can only obtain 25% to 30% of the mulberry content, but also Due to loosening and incomplete carding, it will cause defects in textiles and affect the pass rate
In addition, there are many stiff and parallel threads. After opening and carding, the spinnability of the fibers is poor, and the obtained yarn count is low, so it is impossible to develop textiles with high-grade yarn counts.

Embodiment 1

[0025] First, 30 parts of amino silicone oil and 42.6 parts of octylphenol polyoxyethylene ether (n=10) are added to a mixing kettle equipped with a stirrer and a thermometer. At a temperature of 30°C, stir and mix for 60 minutes to make it a transparent liquid; Then continue to add 45 parts of water at the same temperature under stirring; continue to keep stirring for 50 minutes after adding; finally, the temperature is lowered to room temperature under stirring, and then formic acid is added to adjust the pH to 6.5, and the material is discharged.

Embodiment 2

[0027] First change C 18 29.8 parts of alkyl tertiary amine, C 18 16.7 parts of alkyl fatty acid, 34.7 parts of solid paraffin with melting point of 58℃, C 12 Alkyl fatty alcohol polyoxyethylene ether (n=20, the same in the following examples) 1.5 parts was added to a mixing kettle equipped with a stirrer and a thermometer, and stirred and mixed for 45 minutes at a temperature of 85°C to make it a transparent liquid; Continue to keep the temperature under stirring for 60 minutes; finally, after stirring, the temperature is lowered to 80°C, glacial acetic acid is added dropwise to adjust the pH to 5, and the material is discharged.

Embodiment 3

[0029] First, 35 parts of amino silicone oil, 28.3 parts of nonylphenol-based polyoxyethylene ether (n=10), C 13 Isomerized fatty alcohol polyoxyethylene ether sulfate (n=3~5) 4 parts, C 13 Add 3 parts of isomeric fatty alcohol polyoxyethylene ether phosphate (n=3~5) into a mixing kettle equipped with a stirrer and a thermometer. Stir and mix for 55 minutes at a temperature of 20°C to make it a transparent liquid; 26 parts of water at the same temperature were added dropwise under stirring; after the addition, the temperature was kept and stirred for 50 minutes, and finally the temperature was lowered to room temperature while stirring, and glacial acetic acid was added to adjust the pH value to 4.5, and the material was discharged.

Abstract

The invention discloses a kind of deglued producing method for mulberry fibers. The character lies in: the method includes immersing and expansivity, acid boiling and shelling, cleaning, alkali boiling and hammer washing, desiccation, softening, desiccation and drying, loosing, combing, packaging. The softening agent contains soft smoothing agent and surface activating agent which can form a layer of soft smooth film on the mulberry surface, the alkali boiling may be repeated for 2-4 times. The silk combination rate is decreased from 32% to 5%, the glue residual rate is little than 2-5%, the fiber length reaches 15-40mm. the producing period is shortened for 12-16 days, the condition is convenient.

Description

1. Technical Field [0001] The invention belongs to the technical field of preparing mulberry fiber, and specifically relates to a method for degumming mulberry fiber. 2. Background technology [0002] The main composition of natural bast plant fiber is cellulose, which also contains pectin, hemicellulose, lignin, tallow and water-soluble substances. Mulberry fiber is a kind of bast plant fiber. Its fiber content accounts for about 40-60% of the entire mulberry bark. It is a glue composed of pectin, hemicellulose and lignin other than the epidermis. The quality is covered. The gum content in mulberry is higher than that of other bast fibers such as hemp and ramie. The higher the gum content, the greater the difficulty of degumming. Therefore, to prepare mulberry fiber raw materials for textile use, degumming is the basis and key. [0003] At present, the preparation methods of mulberry fiber degumming that have been reported in the art, such as CN1137071 adopts preparation includi...
