Problems solved by technology

[0005] Textiles dyed with vegetable dyes, especially flax, hemp, and jute blended products dyed with vegetable dyes, have excellent antibacterial and antibacterial properties, but the traditional processing methods of sizing, weaving, and desizing will greatly reduce their antibacterial properties. Therefore, the dyed yarn dyed with vegetable dyes adopts the processing method of free sizing and desizing, and the knitted fabric is free of oil and wax.

Embodiment 1

[0024] Weaving and ecological finishing of blended yarn of hemp fiber dyed with vegetable dyes, tencel and cotton.

[0025] The three-way blending ratio of hemp fiber dyed with vegetable dyes, tencel and cotton is: 10% of hemp fibers dyed with vegetable dyes, 65% of tencel, and 25% of cotton. Carded siro compact spinning 35S is used.

[0026] The blended color spun yarn is directly woven into gray fabric without oil or wax on the knitting equipment, and then washed with water, dried at a low temperature below 140 degrees to set the shape, and then pre-shrunk to become a finished fabric.

[0027] The hemp fiber blended color spun yarn dyed with vegetable dyes is plied and then made into warp yarn, which is woven without sizing on the weaving equipment. The fabric woven without size is calendered at room temperature by a calender or processed by a shrinking machine to become a finished fabric.

[0028] The size-free weaving fabric can avoid the subsequent desizing process, whi...

Embodiment 2

[0030] Weaving and ecological finishing of jute, modal and cotton blended yarn dyed with vegetable dyes.

[0031] The ternary blending ratio of jute, modal and cotton dyed with vegetable dyes is: 15% of jute fibers dyed with vegetable dyes; 55% of modal dyed with vegetable dyes; 30% of cotton fibers. Suction type rotor spinning 16S is adopted.

[0032] The hemp fiber blended color spun yarn dyed with vegetable dyes is plied and then made into warp yarn, which is woven without sizing on the weaving equipment. The fabric woven without size is calendered at room temperature by a calender or processed by a shrinking machine to become a finished fabric.

[0033] The size-free weaving fabric can avoid the subsequent desizing process, which is ecological and environmentally friendly. At the same time, it can retain the antibacterial, anti-inflammatory, and anti-allergic functions of Chinese herbal plant dyes to the greatest extent.

Embodiment 3

[0035] Weaving and ecological finishing of flax and tencel blended yarn dyed with vegetable dyes.

[0036] The binary blending ratio of flax fiber dyed with vegetable dyes and tencel is: 15% of flax fibers dyed with vegetable dyes; 85% of tencel, and vortex spinning 30S is used.

[0037] The blended color spun yarn is directly woven into gray fabric without oil or wax on the knitting equipment, and then washed with water, dried at a low temperature below 140 degrees to set the shape, and then pre-shrunk to become a finished fabric.

[0038] The hemp fiber blended color spun yarn dyed with vegetable dyes is used as the warp yarn and sizing-free weaving on the weaving equipment. The fabric woven without size is calendered at room temperature by a calender or processed by a shrinking machine to become a finished fabric.

[0039] The size-free weaving fabric can avoid the subsequent desizing process, which is ecological and environmentally friendly. At the same time, it can retai...

Abstract

The invention relates to a blended yarn weaving and ecological finishing method for silk-ramie fibers colored by vegetable dyes. One or two kinds of ramie fibers colored by vegetable dyes and silk colored by vegetable dyes and one or more kinds of cotton fibers, Tencel fibers and modal fibers are made into blended colored spun yarns by adopting the spinning modes of compact spinning, Siro compact spinning, spinning conducted through air exhaust type revolving cups and air-jet vortex spinning. The yarns are directly woven into gray fabric through knitting equipment without oil and wax application, and the gray fabric is subjected to water scrubbing and low temperature drying shaping at the temperature lower than 140 DEG C and then is subjected to preshrinking processing to become finished product fabric. The blended colored spun yarns are plied to be used as warp yarns, sizing-free weaving is conduced through tatting equipment, and fabric obtained after sizing-free weaving is calendared by a calender under normal temperature or processed by a preshrinking machine to become finished product fabric. High temperature processing is not needed in aftertreatment of the fabric, finished products have soft hand feel and are smooth, softening agents are omitted, and safety and environment friendliness are facilitated. Besides, the bacterium resistance and inhibition performance of the fabric colored by the vegetable dyes is guaranteed effectively.

Description

technical field [0001] The invention belongs to the textile field. In particular, it relates to a blended spinning weaving and ecological finishing method for silk and hemp fibers dyed with vegetable dyes. Background technique [0002] Flax, hemp, and jute fibers have excellent low-carbon and environmental protection properties. They can be dyed with vegetable dyes and then blended with other fibers to further reflect their properties. [0003] In order to reflect the naturalness, high safety, low carbon, and environmental protection of plant dyes, especially the superior low carbon, antibacterial, and antibacterial functions of flax, hemp, and jute fibers, flax and hemp dyed with natural plant dyes are required , jute, silk, cotton, tencel, and modal fibers cannot be directly blended with colored fibers, which are commonly used in cotton fiber color spinning (raw cotton is carded and then spun after award-winning raw cotton). Because the current white cotton (except organ...
