[0002] The technical field involved in the invention is a fiber composite fabric made of natural colored cotton and tussah staple fibers, which combines the unique advantages of the two and shows multifunctional characteristics. The naturally formed color of colored cotton reduces the chemical pollution of dyeing treatment. At the same time, it is rich in ferrous ions and copper ions, has excellent antibacterial and anti-allergic effects, and is very suitable for infants and people with sensitive skin. Tussah staple fibers, with their high strength, air permeability, and rich protein and amino acids, further enhance the nutrition and comfort of the fabric. After the two are combined, the fabric is not only moisture-absorbing, breathable, and nourishing to the skin, but also has natural anti-smoldering properties and excellent ultraviolet resistance, forming a perfect unity of close-fitting comfort and safety of use.

[0017] This embodiment is further configured such that the impurity rate of the Longlvmian No. 6 natural colored cotton and tussah short fibers described in step 1 is less than 2%.

[0018] This embodiment is further configured as follows: in step 2, the colored cotton uses a cotton cleaner to remove impurities and dust, so that the impurity rate is less than 0.5%, and the tussah short fiber uses a separator to immediately remove fiber bundles and particulate impurities.

[0019] This embodiment is further configured as follows: in step three, 70%±0.5% of colored cotton and 30%±0.5% of tussah staple fibers are evenly fed into a mixer, and the temperature in the workshop is maintained at 27-32°C and the humidity at 50%-70%.

[0020] This embodiment is further configured such that in step four, the mixed fiber web is stretched five times to form fiber strips by air-jet spinning.

[0021] This embodiment is further configured to maintain the temperature at 25-30° C. and the humidity at 60%-80% in step five, and perform edge trimming after weaving is completed.

[0022] The invention also provides a smoldering-proof natural fiber composite fabric produced by a manufacturing method of the smoldering-proof natural fiber composite fabric.

[0023] The detailed connection means are well-known in the art; Step 1: Raw material preparation

[0024] We use Longlv Cotton No. 6 natural colored cotton. This colored cotton is grown naturally, the color is naturally formed, it does not require dyeing, and has antibacterial and hypoallergenic properties.

[0025] Impurity rate control standard: less than 2%.

[0026] The color and fiber structure are stable and suitable for spinning.

[0027] We use high-quality tussah staple fibers, which are rich in natural protein and amino acids, have natural smoldering properties, and help enhance the flame retardant effect.

[0028] Impurity rate control standard: less than 2%.

[0029] The length of the short fibers is 20mm to 50mm, and both the strength and flexibility meet the fabric requirements.

[0030] Step 2: Raw material processing

[0031] Colored cotton processing:

[0032] The colored cotton is cleaned by a cotton cleaning machine to remove impurities such as seed husks and dust, thereby further improving the purity of the fiber and reducing the impurity rate to below 0.5%.

[0033] Use a carding machine to break the colored cotton into a loose fiber web to ensure that the fibers are straight and even, providing basic conditions for the subsequent mixing process.

[0034] Tussah short fiber processing:

[0035] The tussah short fibers are cleaned by separators and cleaning equipment to remove fiber bundles and particulate impurities to ensure fiber quality.

[0036] Combing the fibers separates the fiber bundles into individual fibers to form a soft fiber web.

[0037] Step 3: Fiber Blending

[0038] The colored cotton and tussah staple fibers are weighed and mixed in a ratio of 70%±0.5% of the colored cotton and 30%±0.5% of the tussah fibers.

[0039] Feeding accuracy: The proportion is strictly controlled by an electronic batching machine, and the error is kept at ±0.5%.

[0040] The mixed raw materials are further combed evenly by a carding machine to form a preliminary mixed fiber web.

[0041] The temperature is kept between 27℃ and 32℃ to prevent static electricity on the fibers.

[0042] The humidity should be kept between 50% and 70% to prevent the fiber from drying out and causing a decrease in strength.

[0043] Step 4: Spinning

[0044] Fiber braid:

[0045] The mixed fiber web is fed into a drawing machine and stretched five times to make the fiber strips more uniform and form fiber strips with good linearity.

[0046] Spinning Process:

[0047] The air jet spinning process is used to spin the fiber strips into yarn.

[0048] The yarn twist is controlled at 260 turns / m to maintain a balance between yarn softness and strength.

[0049] The average diameter of the prepared yarn is 10 to 15 tex, ensuring that the yarn is suitable for weaving composite fabrics.

[0050] The yarn is tested for twist uniformity and strength, and unqualified yarns are directly rejected.

[0051] Step 5: Fabric weaving

[0052] The yarn is fed into the textile machine for weaving, according to the plain weave process:

[0053] The density of warp and weft yarns is controlled at about 40 yarns / 2.54 cm and 30 yarns / 2.54 cm.

[0054] After weaving, the fabric feels smooth and has high density.

[0055] Process environment control:

[0056] Temperature: 25℃~30℃.

[0057] Humidity: 60% to 80%, to prevent fiber breakage or uneven weaving.

[0058] Fabric Treatment:

[0059] The edges are trimmed immediately after weaving to prevent the fabric fibers from loosening.

[0060] After physical washing and finishing process, the softness and comprehensive performance of the fabric are improved, while maintaining the smoldering characteristics and natural functions of the fabric.

[0061] Finished product performance testing

[0062] Smoldering detection:

[0063] Flame retardant performance tests are carried out according to GB / T standards to ensure that the fabric can pass standard vertical burning or horizontal burning tests, has excellent smoldering properties, and the burning speed is lower than the specified upper limit in multiple tests.

[0064] Antimicrobial Testing:

[0065] Through antibacterial experiments, the ferrous ions in the colored cotton and the protein characteristics of the tussah fiber showed an effective antibacterial rate (more than 99%), and had a significant inhibitory effect on common bacteria (such as Staphylococcus aureus).

[0066] Physical performance testing:

[0067] The strength, elongation, breathability, moisture absorption and other properties of the fabric meet the national standards for daily clothing and home textile products.

[0068] Main finished product features

[0069] Natural and environmentally friendly: no dyes added, no chemical flame retardants, the raw materials and processes fully comply with green environmental standards.

[0070] Smoldering flame retardancy: It does not support combustion or spread flame after the fire source is gone, and is suitable for scenes with high safety requirements.

[0071] Antibacterial and anti-allergic properties: It has excellent antibacterial and anti-allergic properties, suitable for infants and underwear.

[0072] Comfortable and breathable: moisture-absorbent and quick-drying, good breathability, comfortable to wear, especially suitable for summer clothing and home textile bedding.

[0073] Application Scenario

[0074] Underwear: baby clothing, underwear, pajamas, etc., to enhance skin safety and comfort.

[0075] Home textile products: bedding, curtains, etc., with flame retardant and home protection properties.

[0076] Special clothing: work clothes, protective clothing, etc., used for safety needs in special environments.
