Description
Technical Field
The invention relates to the technical field of Tibetan carpet manufacturing, in particular to a production process of a high-gram-weight non-woven Tibetan carpet.
Background
The Tibetan carpet is a treasure of Chinese national process and is also a living article loved by the world people, the Tibetan carpet is a wonderful flower of the international carpet industry, is a recognized carrier of economic and cultural communications of many countries in the world, successfully holds a Tibetan carpet exhibition for many years, the Qinghai becomes a Tibetan carpet product, technology and capital transaction integrated, an important platform for promoting the rapid development of the Tibetan carpet industry is promoted, the scale of the Tibetan carpet is enlarged year by year, the professional characteristics are increasingly remarkable, the technical level is higher and higher, the Tibetan carpet is developed into the most professional in China and has higher popularity in the world, and the Tibetan carpet becomes one of important windows for expanding the open world, promoting international communications and cooperation and publicizing the blue and green sea.
Traditional tibetan blankets are divided into three categories: firstly, the fabric is formed by weaving yak wool and wool together, the pattern is bright and complex, and the texture is soft; secondly, the fabric is woven by sheep fine wool, the style is simple and light, but the fabric is also woven by colorful yarns to form a thin blanket with more patterns; thirdly, a clamping cushion, namely a cushion, is provided with the false Chinese swertia herb, the highland barley straw or the hay and the like by canvas or cowhide, has firm texture, unique Tibetan carpet weaving method, bright color, simple and lucky composition and rich national style; the carpet surface is fine and soft, the process is exquisite, the appearance is attractive and elegant, and the appreciation value is high; the hair is not lost and faded after washing, and the washing brush is durable.
The raw materials used for carpet production abroad comprise synthetic fiber, wool, viscose fiber and the like, wherein the synthetic fiber accounts for 98.85 percent, while the carpet synthetic fiber mainly comprises nylon, polypropylene and terylene, the occupation rate of the carpet synthetic fiber in the world market is respectively 65 percent, 25 percent and 10 percent, because the nylon has good wear resistance and rebound resilience, the nylon carpet is superior to other chemical fiber carpets and occupies the dominant position of foreign carpet varieties, the production capacity is mainly concentrated in European and American areas at present and accounts for about 79 percent of the total world production capacity, the nylon carpets in the United states and Canada account for about 73 percent of the total carpet amount, and the occupation amount also has the trend of further increasing, the early nylon carpet is made of short fiber, continuous production processes and equipment are developed in succession in the United states, Germany, Japan and the like since 80 years, the growth rate of the nylon is slow, many traditional markets are lost, and at present, the growth rate is kept high only in China and southeast Asia, and the main factor promoting the growth of the nylon dosage still comes from carpet manufacturing industry.
In view of the rapid growth of carpet industry, the non-woven fabric carpet is researched and developed domestically, and has the characteristics of moisture resistance, insect prevention and skid resistance, and the characteristics of larger elasticity, higher hardness and the like than the common carpet, so the Chinese non-woven fabric needle-punched carpet is developed rapidly, particularly, since 2000, the annual increase of the internal and external markets is kept about 20 percent, while meeting the market demand, various production enterprises continuously strive in the aspects of raw material use, product research and development, process innovation and the like, the difficult problem of carpet cleaning is well solved, however, the yield of Chinese carpet is a certain difference from the main foreign carpet producing countries, and at the same time, the color and the pattern are slightly deficient, actually, technical management talents are lacked, the process is not flexible enough, the consciousness of product development and innovation is lacked, low-grade products compete at low price, and the short-term behaviors of enterprises are serious.
For example, chinese patent CN 1729899 a discloses a woven back carpet and a method for making the same, wherein the arrangement of natural latex, synthetic latex, cotton cloth, spot plastic cloth and rubber is used to make the carpet surface level, fine and smooth, vivid pattern, no fading, firm carpet surface, stable fluff, clean carpet edge, anti-skid carpet bottom, and uneasy separation and ventilation, but the traditional carpet using glue process adopted by the carpet is threatened by harmful gas when people use the carpet, causing damage to human body, and having great threat to life safety of human body, and most of the existing hidden carpets are composed of carpet surface and bottom lining, the traditional carpet back glue process is made by manually mixing butadiene styrene rubber with other auxiliary materials such as stone powder, etc., the mixing ratio of glue is not accurate enough, and uneven softness and uneven gluing easily occur during mass production, thereby causing quality problems, further, the world popularization process of the Tibetan carpet is greatly influenced.
