Description

A kapok textile with natural anti-mite function and its processing technology

technical field

The invention belongs to the technical field of textile processing, and in particular relates to a processing technology of textiles with natural mite repelling function, in particular to a processing technology of kapok textiles with natural mite repelling function.

Background technique

Mites are arthropods with tiny body size, generally around 0.1-0.5 mm, invisible to the naked eye, and live off the dead skin, sweat, and oil that the human body sheds. Mites often live in pillows, mattresses, sheets, quilt covers, quilts, sofas, Simmons, carpets, blankets, long-haired toys, fur clothes, mats, etc. Relevant data show that there are 6 million mites on the quilt that has not been dried for three months. The secretions and metabolites of mites are strong allergens, which can cause diseases such as allergic asthma, allergic rhinitis, and allergic dermatitis, and are extremely harmful to children and allergic people. With the improvement of people's living standards, anti-mite functional textiles are more and more favored by consumers. Since the anti-mite effect is usually characterized by the repellent rate, it is also called a mite-repellent functional textile.

At present, there are three main types of anti-mite or mite-repelling textiles on the market: one is the anti-mite fabric obtained by post-finishing the fabric with an anti-mite finishing agent; the other is adding anti-mite drugs to the fiber-forming polymer, Products made of anti-mite fibers by spinning; the third is physical anti-mite fabrics made of ultra-fine fibers and high-density weaving. This method cannot repel or kill mites, and only relies on weaving tightness to prevent the invasion or Through, play the effect of isolating mites. The above methods all have certain limitations. The anti-mite substances used in the first and second methods are all chemical products, not only their manufacture is harmful to the environment, but also if the residual anti-mite chemicals on the textiles exceed the standard during use, they will also bring safety hazards to the human body, and the second This method is only applicable to chemical fibers. In the third method, the holes in the textiles are increased due to the fact that the textiles need to be worn and washed during use, and the yarn becomes thinner, thereby gradually losing the anti-mite effect.

Kapok fiber is the fruit fiber of several plants in the Malvaceae Kapok family. It has outstanding characteristics such as hollow, light, thin, and soft. It is a new type of natural fiber to be developed and utilized. At the same time, kapok fiber has very good special functions such as natural repellent mites. According to the test of GB/T24253-2009 "Textile Anti-mite Performance Evaluation", the mite repellent rate of natural kapok fiber is generally above 95%, and the mite repellent rate is greater than 60%. %, it is determined that the sample has anti-mite effect. Kapok textiles, because the fiber production process can absorb carbon dioxide and prevent soil erosion, are beneficial to the environment and have no negative impact on the human body during use. They are truly green and low-carbon textiles.

However, our research found that the current textile processing technology has greatly damaged the mite repelling function of kapok fiber. The dyeing and finishing process is like boiling Chinese medicine. , so that the mite repelling rate of existing kapok blended fabrics is generally less than 50%; while the mite repelling rate of natural yarn or gray cloth containing 20% kapok is above 80%, indicating that spinning and weaving processing does not affect the mite repelling of kapok Effect: After the kapok fiber is baked in a gaseous medium at 140°C for 40 minutes, there is almost no loss in the repellent rate, indicating that the common dry finishing process of textiles has little effect on the mite repellent function of the kapok fiber. Therefore, we have researched and developed the following new processing technology, which should not damage the natural function of kapok fiber, and can satisfy contemporary consumers' pursuit of healthy, green and harmonious textiles with nature.

Contents of the invention

The technical problem to be solved by the present invention is to provide a kapok natural mite repelling functional textile and its processing technology.

The present invention also provides the processing technology of the above-mentioned kapok textiles with natural anti-mite function, which is characterized in that, comprising the steps of:

Step 1): After opening and mixing natural kapok fibers and other fibers in proportion, kapok blended yarns are produced by ring spinning or rotor spinning equipment;

Step 2): kapok blended yarn obtained in step 1) is purely woven or interwoven with other yarns to make knitted fabric or woven fabric;

Step 3): The knitted fabric or woven fabric obtained in step 2) is sequentially processed through kapok gray cloth, scouring or soaping, softener finishing, dehydration, drying, and tentering to make a product.

Preferably, when the kapok blended yarn in the step 1) is a non-white colored yarn, other fibers are colored fibers.

Preferably, the technical parameters of the scouring in the step 3) are: the concentration of lye is 0.1-30g/L, the temperature is 10-100°C, and the duration is 10-250min.

Preferably, the process parameters of the soaping in the step 3) are: the soaping temperature is 10-60° C., and the soaping time is 10-100 min.

The mite repelling rate of the natural kapok fiber provided by the invention is above 95%; the mite repelling rate of the yarn or gray cloth containing 20% of kapok is above 80%, and the spinning and weaving process does not affect the mite repelling effect of kapok; There is almost no loss in the mite repelling rate after baking in a gaseous medium at 140°C for 40 minutes, and the common dry finishing process of textiles has little effect on the mite repelling function of kapok fiber.

The beneficial effects of the present invention are: (1) the anti-mite function of textiles can be realized without adding chemical anti-mite reagents, the product is green and environmentally friendly, and has no side effects of chemicals; Containing a lot of still air, kapok products feel smooth, soft, fluffy, and have a good thermal insulation effect; (3) The finishing process adopts low temperature, low acid and alkali concentration, and short process processing, which can greatly reduce the consumption of resources such as water, electricity, and chemicals.
