A kind of cold yarn and its preparation method and application

Abstract

The invention belongs to the field of textile manufacturing, and particularly relates to a cold yarn thread and a preparation method and use thereof. The raw material components of the cold yarn thread includes ore masterbatches, polyarmide fibers and an anti-ultraviolet agent, wherein the ore masterbatches are prepared by grinding jade ore, rock crystals, silver ore and copper ore; and a cold yarn having an anti-ultraviolet function can be prepared by knitting the cold yarn thread. The prepared cold yarn thread and the prepared cold yarn have excellent moisture-absorbing heat-absorbing, heat-dissipation, cold and breathable characteristic and a lasting anti-ultraviolet performance, and can be prevent more than 96% of ultraviolet light, and the breathable cold feeling degree can reach 0.336; a fabric woven by the cold yarn thread can be especially used in summer; and the cold yarn thread and the cold yarn have an anti-static function, are flexible in fabric performance, are washing-resistant, are durable, can avoid disconnected yarns, can avoid pilling, and are safe and environment-friendly. The preparation method is simple to operate, is low in cost, is available in raw material, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of textile manufacturing, and in particular relates to a cold yarn and a preparation method and application thereof. Background technique [0002] With the continuous progress and development of society, people's cognitive level is also constantly improving, and they pay more and more attention to their own safety. The protection of clothing, which is the first priority in "basic clothing, housing and transportation", is also more and more valued. As we all know, the intensity of ultraviolet radiation is the strongest throughout the year, especially in summer. In the hot summer, if the skin is exposed to strong sunlight for a long time, it will be sunburned by ultraviolet rays. Short-term exposure will promote the increase of melanin synthesis. It can lead to hyperpigmentation, such as dark spots, freckles, chloasma, etc., which will increase, increase, and darken, affecting the appearance of the skin. If it is ex...

Problems solved by technology

[0003] At present, there are two main types of fabrics with anti-ultraviolet function on the market: one is to use the thickness of the fabric to shade the sun to prevent ultraviolet rays, but if this type of fabric is too thin, the anti-ultraviolet effect is poor, and if it is too thick, it is not suitable for summer and is not accepted by the market. Accept; the other is to coat an anti-ultraviolet chemical potion coating on the knitted fabric to produce a certain anti-ultraviolet effect

But at present this fabric also has two major defects: (1) the anti-ultraviolet effect of the anti-ultraviolet fabric produced by this method is also relatively poor, and the UPF value is only 10~20; (2) the anti-ultraviolet effect is not durable, after 2~ After 3 washes, the UPF value will drop below 10, and the fabric basically has no anti-ultraviolet effect

Cooling fabrics currently on the market are commonly made of polyester (PET) which is knitted and colored and then coated with a cooling agent coating to make the skin feel cool after wearing it. This type of fabric will disappear after washing three to five times. loss of effect
