Technical Field

The invention relates to the technical field of functional textile fabric production, in particular to a production process of a filament rayon slub fabric.

Background

Due to the enhancement of the consciousness of returning to nature and health protection, functional finishing mainly based on comfort, cleanness, health care and sanitation becomes the subject of the development of textile dyeing and finishing in the century. Meanwhile, with the development of industry, the environmental pollution is increasingly serious, carbon dioxide, nitric oxide and sulfur oxide in the atmosphere are increased, the influence on human bodies is large, and the number of people with allergic constitution is increased, so that the skin care function arrangement attracts attention of people, and more garment fabrics contacting with the skin tend to meet the consciousness of nature and environmental protection. The development of the textile with skin care and health care functions by utilizing natural substances is in line with the development trend, and the product is very popular with consumers.

Under the strong development of science and technology and economy, textiles are no longer textiles in the traditional sense, and they are endowed with a completely new sense. In the past, clothes mainly used for keeping warm are not only provided with simple functions but also provided with simple functions. Besides pursuing beauty, fitness and comfort, the clothes are also expected to be beneficial to skin health, and even have the functions of preventing and treating diseases, so that the skin-care and health-care functional finishing of the textile is more and more valued by people. With the change of social environment, the improvement of living standard of consumers and the diversification of requirements, a plurality of functions are provided for textile materials and clothes to meet the new requirements of environment and physiological requirements. Therefore, multifunctional finishing of textile materials and garments has been rapidly developed. Just as the international well-known clothing trend analysis, aldrich, says: at present, a new trend appears in textiles, namely, the effect of preventing and treating diseases is achieved by utilizing clothes worn by people, so that the life of people is greatly changed, and people are entering a new era of endowing the fabrics with real skin care and health care functions.

The skin care health care fabric extends the original concept, extends from facial skin care to whole body skin care, and extends from general nutrient skin to the level of cleanness, sanitation and comfortable health care. The skin care agent which is very similar to cosmetics is processed and finished on the fabric, and the comprehensive care of the skin of a human body can be realized by wearing the clothes.

Capsicum is of Capsicum of Solanaceae, also called Capsicum annuum, Capsicum frutescens, and Solanum muricatum. The tropical region of the original south-central America is introduced into Europe at the end of 15 th century, is introduced into Japan at the end of 16 th century, is introduced into China in the end of Ming dynasty, and has more than 300 years of cultivation history in China. The method is mainly used for cultivating sweet peppers in cold countries, and mainly used for cultivating peppers in tropical and subtropical countries. The hot pepper with strong spicy taste is cultivated from north Africa to Arabic, China and south-east Asia and provinces of the northwest, the southwest and the south China, and forms a famous hot belt in the world. The edible part of the pepper is a fruit and is a common vegetable. The ripe berries are red or orange yellow, spicy and hot, and are an important good seasoning product with high nutritional value and health care function, and the fruits, roots and stems of the berries can be used as medicines, so that the effects of invigorating stomach, promoting digestion, promoting blood circulation and reducing swelling are achieved.

The capsaicin has antibacterial, antitumor, analgesic and anti-inflammatory effects on digestive system, cardiovascular system, respiratory system and nervous system, and can be used as stomach invigorating agent for stimulating appetite and improving digestion. It has effects in promoting gastric secretion, stimulating appetite, promoting blood circulation, improving disease resistance, relieving flatulence, stomach cold, diarrhea, dyspepsia, expelling intestinal parasites, and inducing perspiration. Therefore, the capsaicin has higher application value in the aspects of food, catering, livestock and poultry feed, medical drugs and the like. The diseases for which capsaicin is successfully used for clinical treatment are: diabetic neuralgia, postherpetic neuralgia, rheumatoid arthritis and osteoarthritis, psoriasis, and the like.

The main function of the capsanthin is shown in that the capsanthin has vitamin A activity and has the functions of nutrition, health care and cancer resistance. The capsaicin finishing is applied to the fabric, belongs to thermal sense finishing, and can promote blood circulation, regulate metabolism and produce heat storage and warm keeping effects.

The fabric prepared by the fancy yarn has no report on skin care and health care, so that the fabric prepared by the fancy yarn with skin care and health care is required to be produced. And the conventional rayon fabric is dyed on the full-compact equipment, so that two problems exist: firstly, the strength is low, the tension of the equipment on the fabric is too large, the fabric is easy to break, and secondly, the fabric is easy to wrinkle during dyeing; if the dyeing is carried out on loose or intermittent tight equipment, the head-tail color difference and the cylinder difference are serious. This is because the wet strength of ordinary viscose fibres is about 50% lower than the dry strength.
