Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to cellulose protectants and the use of such preservatives in the simultaneous bleaching of fabrics.

Blancii of cloth (Jinge) at the laundry factory
ssage) is carried out on a machine that washes Daiyuzumi's cloth.

A certain kind of irrigation system that performs discontinuous watering is 6K, electric power 4I! A similar type of machine is the so-called anti-layer dewatering machine, which processes 50 to 20.0 fabrics per operation.

Another cleaning system that performs continuous erosion is 600 to 100 Hz per hour.
It is a “tunnel” type device that processes oo kg of cloth.
These devices are being replaced by older, less reproductive "carousel" equipment.

``Carousel type equipment'' refers to a device for continuously spinning cloth. This device consists of a washing machine with a horizontal cylinder similar to a domestic washing machine.
They have the name "carousel" because they advance gradually on a circular surface. Continuous spraying is carried out sequentially as the five sections progress by a oscillating cam that controls these operations. Addition of water, heating of the bath, and circulation of detergent are performed automatically, but at the same time as loading the cloth. Drying is done later.

Washing machine is a basic device for continuous washing of cloth. There are two types of nine-level tunnels. The seventh type is about 270'9 axis with 1!21 left and right sides.
Consisting of 100 pieces made of rotating stainless steel.

Anti-monme is performed by hitting. The charging amount is 7 compartments.
c 30~! The survival time in the O-en and Ashi Valley section is to!
The duration is between 3 minutes and 3 minutes. Advance r with regular spacing of holes
c.) Performed by rotating the shaft completely.

These tunnels have 10 to 6 compartments, and various operations are carried out as the laundry (cloth) moves through the tunnel. The addition of detergent is done automatically. The λ-th form is called a module tunnel.
This is because it has been directly replaced with a laundry module that enables detailed work to be carried out.

In laundry factories, detergents are used which are gender VC formulated compositions to meet the special requirements of laundry in this industry. Unlike garden washing, soft water is very often used. The cycle duration is relatively short for productivity purposes. For this reason, the detergents used are extremely alkaline and Cf14 cough melons are rare. Both eyes are carried out using ``Jiahani Shienai Natrikumuna'', that is, ``Javuel Water''.

Toto 1 of the hospital-use laundry! In order to facilitate the removal of blood spots, a thorough pre-cleaning with a detergent containing the enzyme protease is recommended for the use of T-based disinfectants in hospitals. I started to get annoyed. The disinfectant contaminates most cloths, sheets, staff's white coats, towels, etc.

Products based on gluco/chlorhexidine acid are extremely difficult to remove from hospital washes and have a major drawback in that they form chlorine compounds and yellow-brown, hard-to-remove compounds during section 1 cleaning. has. These spots accumulate depending on the number of times the laundry is used, and the laundry becomes unusable before it is worn out.

In order to avoid the formation of these spots, it is recommended to abolish festivals where sodium hypochlorite is used. Using may prevent the formation of yellow spots. Hydrogen peroxide and its 04 forms.

Similar M rice can also be obtained by using sodium perborate, sodium perborate, sodium perborate, sodium peroxide, peroxygen, etc. In fact, the results of laboratory and industrial tests show that the formation of this spot on such agents containing sigluco/chlorhexidine can be avoided by y14-hydrogen and its derivatives. showed that.

In hospital washing and refurbishment, the washing steps are in the following order: Moistening at knee presentation, Pre-washing at 30~≠OI', Washing at 60)' to 1rzc, Rinse, Salting at cold time. Mengbai - Rinsing, Neutralization, Nana In the original method using hydrogen peroxide and its conductor, the brewing process is carried out at the same time as the cleaning operation; that is, the steps are carried out in the following order: Pre-cleaning at a wet temperature of 830~≠Q°C using hydrogen peroxide, persalt or percarbonate, etc. Simultaneous cleaning and bleaching, soot, neutralization and rinsing at 0°C. However, the use of such substances as 7% peroxide or dα mainly carries the risk of decomposition of cellulose. Therefore, it was difficult to implement.

The inventor added H and hydrogen to the cleaning bath at the same time.
We have researched a cellulose protective agent that can remove hot water that cannot be removed due to the nature of the fabric.

The loading agent of the present invention is composed of a combination of organophosphon sales and four organo rDmu bodies. This protective agent can be used in the form of an aqueous solution of an organophosphonic conductor and an organophosphonic conductor, or a water bath solution of an organophospho/polar conductor and an organo-nts conductor in whole or in part in the form of crystals.

The effectiveness of the preservative is determined by measuring the concentration DP of cellulose in the woven fabric EMPAJ O/M10.

In many laundry plants, which clearly show the advantages of BL-, the addition of chemicals is done automatically, and it is sufficient to prepare a detergent solution. The supply system automatically introduces the required amount of chemicals for each trough cycle, both in the carousel and in the "washing tunnel" type.

In the case of the present invention, the washing liquid 41 is the same as in the conventional method.

This ff! The solution is stable and can be used for several weeks.

A neutralizing solution containing acetic acid and optionally sodium bisulfite to remove residual active hydrogen is vI4i for each installation as required.

Wash #1 - A similar system for washing chemicals can be used in the case of discontinuous washes in a water press.

However, in many laundry plants the machine operator manually introduces the washing agents: powdered or liquid detergent, hydrogen peroxide or perborates or percarbonates, and protectants. When using solid whitening agents in powder form, such as solid salts or percarbonates, it is also possible to introduce protective agents into the detergent solution to facilitate the addition of chemicals. When using a liquid bleach such as hydrogen peroxide, a protectant is added to the eye opener solution.

After this experiment, a cellulose separation test was conducted on a woven fabric that had been washed several times using the method of the present invention and a woven fabric that had been washed in the same manner using a conventional method using hypochlorite.

The results obtained were as follows: These results show a very good effect of the protective agent "OraJsan BL-". The laundry from 30 onwards is processed.The waiting time in the compartment 'a' is 2 minutes.
