Anti-mite Spunlace Nonwoven Fabric Product

I. Product Foundation: Diverse High-Quality Base Materials, Suitable for Different Anti-mite Scenarios

The protective effect and adaptability of anti-mite spunlace nonwoven fabric start with the precise selection and scientific proportioning of raw materials for spunlace base materials. Our company carefully selects various high-quality fibers such as polyester, viscose, pure cotton, and bamboo fiber, and combines the usage requirements and characteristics of different scenarios to create spunlace base materials that are both basic in performance and suitable for anti-mite applications, providing a stable carrier for subsequent anti-mite post-treatment processes:

Polyester Fiber: Endows the base material with excellent tensile strength and tear resistance, ensuring that the base material does not deform or break during anti-mite processing, cutting and shaping (such as mattress covers, curtains), and long-term use. At the same time, it has good chemical resistance and aging resistance, which can resist the erosion of anti-mite agents and environmental factors, ensuring the long-term stability of the anti-mite effect, suitable for long-lasting durable home scenarios; 

Viscose Fiber: Has excellent moisture absorption and breathability, which can quickly absorb moisture in the environment and reduce the humid environment suitable for mites. At the same time, its soft and skin-friendly touch makes the product more comfortable when in contact with the human body (such as bedding, baby clothes), suitable for scenarios with high requirements for skin feel;

Pure Cotton Fiber: Natural, environmentally friendly, and biocompatible, non-irritating, odorless, and with excellent moisture absorption and breathability, it can keep the usage environment dry. After anti-mite post-treatment, it becomes the preferred base material for home products for infants and sensitive skin people, suitable for scenarios with strict requirements for safety and comfort;

Bamboo Fiber: Has natural antibacterial factors (bamboo quinone), which can help inhibit the breeding environment of mites. At the same time, it has good breathability and environmental degradability, in line with the trend of green and healthy consumption. After anti-mite treatment, it forms a "double protection", suitable for high-end home, personal care and other scenarios that pursue both naturalness and functionality.

We flexibly adjust the raw material ratio according to customer needs - for durable scenarios such as mattresses and curtains, the proportion of polyester can be increased (such as 60% polyester + 40% viscose), while for scenarios such as baby bedding and close-fitting clothing, pure cotton / bamboo fiber is mainly used. Each batch of base materials undergoes multi-dimensional testing such as weight (adjustable from 30-180g/㎡), thickness, strength, and breathability, with errors controlled within a very small range to ensure the stability of base material performance and lay a solid foundation for the precise implementation of anti-mite post-treatment processes.

II. Core Process: "Spunlace Base Material + Anti-mite Post-treatment", Achieving Long-lasting Anti-mite Effect

Our anti-mite spunlace nonwoven fabric strictly follows the step-by-step process of "first making spunlace base material, then doing anti-mite post-treatment". According to the characteristics of different base materials and anti-mite requirements, we customize and optimize the post-treatment plan, and through refined control, achieve the three guarantees of "stable base material + uniform anti-mite + long-lasting effect", effectively inhibiting the breeding of mites from the root: 

(1) Pre-treatment of Spunlace Base Material: Enhancing the Adhesion of Anti-mite Agents

Before anti-mite post-treatment, we conduct targeted pre-treatment on the spunlace base material to create conditions for the uniform adhesion and long-term retention of anti-mite agents: For substrates with strong hygroscopicity such as viscose, pure cotton, and bamboo fiber, low-temperature drying (at 60-70℃) is adopted to remove the excess surface moisture, avoiding the impact of moisture on the uniformity of mite repellent penetration and preventing mold growth due to dampness, ensuring a stable processing environment for mite-proofing.

For synthetic fiber substrates like polyester, plasma surface treatment technology is used to slightly activate the surface active groups of the fibers, enhancing the binding force between the mite repellent and the fibers, reducing the shedding of the mite repellent during subsequent use, and extending the mite-proofing duration.

(2) Fine mite-proofing finishing: Customized long-lasting mite-proofing solutions

Relying on a customized mite-proofing finishing production line, based on the customer's requirements for mite-proofing level, duration, and usage scenarios, mite repellents that meet national environmental protection standards (such as pyrethroids and natural plant extracts) are selected, and differentiated processing techniques are implemented to ensure safe and efficient mite-proofing effects:

Selection of mite repellents: Strictly select mite repellents that comply with the GB/T 24253-2020 "Evaluation of Mite-Proofing Performance of Textiles" standard - for home and baby care scenarios, use mild and non-irritating natural plant extract mite repellents (such as eucalyptus oil and menthol oil derivatives) to avoid irritation to the human body; for medical and long-term use scenarios, use long-lasting and stable low-toxic pyrethroids (such as permethrin and cypermethrin) to ensure long-lasting mite-proofing effects and compliance with safety standards. All mite repellents have passed third-party testing and have no harmful residues.

Application process of mite repellents: Select the appropriate application method based on the characteristics of the substrate fibers to ensure uniform coverage of the mite repellent on the surface and inside of the substrate:

For hygroscopic substrates such as viscose, pure cotton, and bamboo fiber, the "immersion - squeeze" process is used, completely immersing the substrate in the mite repellent solution (the concentration of the mite repellent is adjusted to 0.5%-2% as needed), and controlling the liquid content (60%-80%) through a squeezing machine to ensure that the mite repellent fully penetrates the fibers and avoids insufficient mite repellent in certain areas.

For substrates with poor hygroscopicity such as polyester, the "spraying - drying" process is used, evenly spraying the mite repellent on the substrate surface through high-precision nozzles (atomization particle size 5-10μm), with real-time monitoring of the spraying amount (adjustable from 3-8g/㎡), and combined with the uniform movement of the conveyor belt to ensure no missed or excessive spraying, achieving uniform distribution of the mite repellent.

Curing and shaping process: After the application of the mite repellent, a customized curing plan is developed based on the type of mite repellent:

Natural plant extract mite repellents are cured at low temperatures (70-80℃) to avoid high temperatures destroying their active components while ensuring the initial binding of the mite repellent to the fibers.

Pyrethroid mite repellents are cured at medium temperatures (100-120℃), with precise temperature control to enhance the chemical bond between the mite repellent and the fibers, ensuring that the product maintains excellent performance after multiple washes (for washable models, the mite-proofing rate remains ≥85% after 20 washes) and friction, and the mite repellent does not easily fall off, providing long-lasting mite-proofing effects (the mite-proofing duration can reach 2-3 years under normal indoor usage scenarios).

Three. Product advantages: Multiple characteristics combined, building a strong mite-proof barrier

With diverse high-quality substrates and fine mite-proofing finishing processes, our mite-proof spunlace non-woven fabric has multiple core advantages, which can flexibly meet the mite-proofing needs of different fields and create a safe and healthy mite-free environment for users:

Highly effective and long-lasting mite-proofing: The repellency rate for mites (such as house dust mites and dust mites) is ≥90%, and the inhibition rate is ≥85%, effectively reducing mite breeding and mite excrement (the main allergen) from the source. The mite-proofing effect is long-lasting - for household products, the mite-proofing effect can be maintained for 2-3 years under normal use, and excellent performance can still be maintained after multiple washes, eliminating the need for frequent replacement. Strong material compatibility: It covers various base materials such as polyester, viscose, pure cotton, and bamboo fiber, allowing flexible selection based on scene requirements - polyester for durable scenes, pure cotton / bamboo fiber for skin-friendly scenes, viscose for moisture-absorbing scenes, achieving "one material for one scene, one solution for one demand", meeting different product positioning of customers;

Safe and non-irritating: The selected mite repellents and raw materials all comply with national environmental protection and safety standards (such as OEKO-TEX® Standard 100), without the release of harmful heavy metals or volatile organic compounds. They have passed skin irritation tests (no redness, itching, or allergic reactions), and can be safely used in scenarios involving infants and young children, sensitive skin individuals, and medical settings, providing greater peace of mind during use;

Balanced basic experience: Beyond the mite repellent function, the basic properties of the base materials such as breathability, skin-friendliness, and strength remain unaffected - pure cotton and bamboo fiber base materials are soft and skin-friendly, viscose base materials are moisture-absorbing and breathable, and polyester base materials are strong and durable, ensuring that the product can perform its mite repellent function without sacrificing comfort and service life during use.
